Description

  The present invention is aimed at pain relief and protection of interphalangeal joints to treat pain and swelling of interphalangeal joints due to osteoarthritis of the fingers such as Heberden's nodules or rheumatism The present invention relates to finger protection equipment.

  Osteoarthritis of the fingers, such as Heberden's nodule, begins with the occurrence of cartilage damage at the interphalangeal joints of the fingers due to human aging, and the osteophyte formation associated with the degenerative change of the articular cartilage changes proliferatively Disease.

  The Heberden nodule usually progresses slowly from about 40 years old and tends to increase with aging, and the cause is unknown at this stage. Swollen and pain / redness on the back side of the part (first joint (distal interphalangeal joint) or second joint (proximal interphalangeal joint)), and then progresses to the interphalangeal A bone-like protuberance due to osteophytes is revealed on the back side of the joint, and a hard nodule is formed. If the joint progresses further, bending deformation occurs in the interphalangeal joint, and if the joint cartilage destruction progresses and the joint becomes unstable, lateral displacement of the fingers and subluxation may occur, and the interphalangeal joint The skin on the dorsal side of the head may become thin and blisters called mucinous cysts may form, and during such periods, movement pain may occur during use of the fingers, and even a little on the back side of the interphalangeal joint If you touch something, your fingers will run severe pain.

  When the Heberden node enters the remission phase, the progress of flexion and deformation of the interphalangeal joints subsides, and the inflammatory symptoms in the acute phase disappear and the pain is relieved.

  Therefore, the Heberden nodule disease is understood as a spontaneous remission disease, and there is a tendency that treatment is not actively given.

  However, since Heberden's nodule disease is attacked by severe pain in the acute phase, patients with Heberden's nodule cannot tolerate such severe pain and will receive medical examinations for pain complaints. Become.

  As a current treatment method for the Heberden nodule disease in such a medical institution, symptomatic treatment is mainly used for pain, and an internal medicine or an external medicine (an application medicine or a paste) is used as an anti-inflammatory analgesic treatment. Yes. However, such treatment seems to have little effect on local pain, movement pain when using fingers, and things touching or hitting the back side of interphalangeal joints It can be said that it is not very effective for measures against pain at times.

  Therefore, as a countermeasure against such pain, at the present stage, it is said that it is effective to perform rest fixation of the interphalangeal joint part of the fingers. Surgical treatment of interphalangeal joints and external fixation of fingers were used.

Special table 2008-545490

  Among them, surgical treatment for interphalangeal joints is based on a tolerable purpose or forced deformation and pain relief when strong pain remains due to deformation of interphalangeal joints or when the fingers are damaged. This is a therapy to fix the interphalangeal joint for the purpose of restoring the finger function, and it is effective when the deformation of the interphalangeal joint, such as subluxation and lateral displacement, is advanced It can be said that it is an effective treatment method.

  However, in such surgical treatment, the purpose of pain relief is achieved by performing an operation to fix the interphalangeal joint, but the interphalangeal joint becomes permanent after healing of the Heberden nodular disease over time. There are many cases of crawling that it does not move, and if the Heberden nodule disease recurs after surgery and a mucinous cyst develops, or the mucinous cyst causes thinning of the skin on the back side of the interphalangeal joint In such a case, it is necessary to perform a new operation for the purpose of excision of mucinous cysts and regeneration of the skin.

  Therefore, a so-called finger external fixation method is attracting attention as a treatment method for pain countermeasures in place of surgical therapy.

  The external fixing method is a method of performing rest fixing by surrounding the interphalangeal joint from the outside, and as the external fixing method, a method of fixing the interphalangeal joint by winding taping around the fingers. A reactive resin material is coated on a flexible medical material made of woven or non-woven fiber, and the reactive resin material is immersed in water to be active-cured to produce a non-woven splint (see Patent Document 1) or other cine The method of winding is adopted.

  However, this external fixation method is not an effective means for reducing the burden when using fingers with subdislocation or subluxation of the interphalangeal joint during progression of Heberden's nodule disease, In the period when the symptoms of pain are strong, there is a possibility that it may not be a particularly effective means when the progress of the deformation and destruction of the interphalangeal joint is large.

  Therefore, as a kind of external fixing method, there is known a method of inserting a finger protection device, which should be called a medical cast or a plastic cast, made of a resin molded body (see Non-Patent Document 1).

  Such finger protection devices have been attracting attention because they can fix and treat the interphalangeal joints simply by inserting them into the fingers. A belt-shaped winding portion configured to wind the wire, and a curved stopper portion that is connected to the belt-shaped winding portion and abuts against the finger tip portion. The belt-shaped winding portion is wound around the interphalangeal joint portion in a state of being in contact with the distal end portion, and then the winding shape of the belt-shaped winding portion is held by an adhesive tape.

  Therefore, such a finger protection device winds the adhesive tape in a state in which both ends of the belt-like winding part are overlapped with each other, so that it becomes very thick when worn on the finger, and the Heberden nodule disease Therefore, it is difficult to sufficiently adapt to the shape of the periphery of the interphalangeal joint, which causes wrinkles, and the fixing function of the interphalangeal joint may not be sufficiently exhibited.

  In this case, the finger with Heberden's nodular disease has a strong tendency for the interphalangeal joint to protrude to the back side, and the phalanx is simply in contact with the tip of the finger. Even if the belt-like winding part wound around the interarticular part is fixed with an adhesive tape, the phalanx part (the terminal part, the middle part or the base part) existing on both sides of the interphalangeal joint part is a phalanx. Since it is thinner than the inter-articular part, the band-shaped winding part of such a finger protection device does not fit the shape of the finger exactly, and a large gap is inevitably created between the fingers and the interphalangeal joint There is a possibility that the fixing of the part becomes insufficient.

  In addition, the hand protection device is very easy to move in the longitudinal direction of the finger during use and is easy to drop off.In addition, there is a sense of discomfort and it can never be said that it is comfortable when used for a long time. It can be said that it is difficult for individual users to freely attach and detach.

  In addition, such a finger protection device is wound around a finger in a state where both ends of the belt-shaped winding part are overlapped with each other, so that it is very thick and other fingers adjacent to the attached finger Fingers interfere with each other, the gap between adjacent fingers becomes large, the insertion feeling is bad, and the tip of the finger is covered with the stopper part, so the finger is covered with something It becomes difficult to grasp the feeling when touched.

  Therefore, the present invention provides an external fixation method that can be easily inserted into a patient's finger against osteoarthritis of the finger such as Heberden's nodule disease or rheumatism, and can fix the interphalangeal joint from the outside. Improve the adaptability to the shape of the fingers, and ensure that the interphalangeal joint is fixed so that it does not move excessively when the fingers are used after being inserted once Another object of the present invention is to provide a finger protection device that can be easily removed from a finger during use and has an improved feeling of insertion.

  The finger protection device according to the present invention comprises a cylindrical insert from a resin molded body whose basic shape is substantially circular in cross section and both ends are mutually open ends in order to enable insertion into fingers. The cylindrical insertion body is a phalanx having one interphalangeal joint portion of the finger at the center and an end surface of one open end of the both end open ends on the distal end side of the interphalangeal joint. The first finger of the tubular insert has a length dimension until the end surface of the other end side opening end portion faces the finger segment located on the proximal phalanx side. A concave enveloping portion is formed on at least an inner wall of a portion facing the osteophyte protuberance on the back side of the internode joint, and the osteophyte protuberance is encased in a state where the osteophyte protuberance is close to or abutting, and further, the cylindrical insertion An inner wall of at least one of the one end side opening end and the other end side opening end of the body has a finger Forming a constriction holding portion elastically contacting the part, it is characterized in that the tubular insertion member is configured to be retained the state of being inserted into the finger.

  According to the present invention having such a configuration, the concave wrapping portion is wrapped in a state where the concave wrapping portion is close to or in contact with the raised portion of the osteophyte in the back portion of the interphalangeal joint portion of the finger, and the side portion of the finger is held tightly. Since it is elastically held by the part, the interphalangeal joint can be securely inserted and fixed in a state where the finger is positioned at a predetermined position. The bone and spine protuberances are constantly encased in a predetermined position within the concave envelopment part, and the interphalangeal joint can be firmly fixed in a state that conforms to the shape of the fingers without moving to the flood. Moreover, since the side of the finger is elastically held by the stenosis holding part during use, it cannot be easily detached from the finger, and it is extremely free to use the finger in everyday life. And flights It is it is possible to admit. In addition, since it is easy to attach and detach the cylindrical insert to the finger, it is possible for the patient himself to repeat the attachment and detachment of the cylindrical insert many times in daily life, so that the disease treatment can be performed very easily. be able to.

  In addition, the cylindrical insertion body can be manufactured as a resin molded body molded using a gypsum mold made by shaping a finger in the disease. Therefore, the insertion feeling can be remarkably improved because a large gap is not formed between adjacent fingers.

  Further, the cylindrical insertion body has an end surface at one end side opening end portion opposed to a phalanx portion existing at the distal end side of the interphalangeal joint portion and an end surface at the other end side opening end portion existing on the proximal phalanx side. Since it has a length dimension until it is opposed to the phalanx, the tip of the finger is exposed to the outside, and it is easy to grasp the sensation when an object touches and does not cause a disease Other interphalangeal joints can also be exposed without affecting the motor function of the other interphalangeal joints.

  Further, the present invention may be configured by forming a planar portion at a palm side portion of the tubular insert that faces the abdomen side of the finger.

  With this configuration, even if the palm side portion is strongly pressed against an object or the like, a planar portion is formed, so that the pressing force acts as a component force that pushes the concave enveloping portion outward. It is impossible to prevent the concave enveloping part from being greatly separated from the osteophyte bulge during use, and the inner wall of the tubular insert is always close to or in contact with the interphalangeal joint. The fixing function of the joint portion can be further improved.

  Moreover, this invention is the said other end side opening end of the said cylindrical insertion body in the site | part which opposes the said abdominal part side and back part side of the said finger joint in the said one end side opening end part of the said cylindrical insertion body. You may make it comprise and form the 1st concave arch-shaped notch part which became a concave arch shape on the part side, respectively.

  With this configuration, even if the finger is used while the tubular insert is attached to the finger, the palm or back on the fingertip side of the phalanx having the open end on the one end is the first concave arcuate cut. The presence of the notch is surely exposed so that the sense of touching an object can be easily grasped, the insertion sense can be wiped off, and the first concave arc Since the notch has a concave arch shape, it does not affect the elastic contact holding function to the side of the finger by the constriction holding part formed on the opening end side of one end side, and the fixing function of the interphalangeal joint part is deteriorated I will not let you.

  Further, the present invention provides the one end side opening side of the cylindrical insertion body at a portion facing the abdomen side and the back side of the phalanx part at the other end side opening end part of the cylindrical insertion body. A second concave notch portion having a concave arch shape may be formed respectively.

  With such a configuration, even if the finger is used while the tubular insertion body is attached to the finger, the palm part or the back part on the fingertip side of the phalanx part where the opening part on the other end side exists has the second concave arch shape. The presence of the notch is surely exposed so that the sense of touching an object can be easily grasped, the insertion sense can be wiped away, and the second concave arc shape Because the notch has a concave arch shape, it does not affect the elastic contact holding function to the side of the finger by the stenosis holding part formed on the opening end side of the other end, and the interphalangeal joint fixing function Will not deteriorate.

  Further, according to the present invention, an outer end side of the cylindrical insertion body is opened across the second concave arcuate cutout portion existing on the back side of the pair of second concave arc cutout portions. A slit portion may be formed, and an indexing hole communicating with the inner end side of the slit portion to stop the slit portion may be formed.

  With this configuration, when the cylindrical insert is attached to the finger, the slit portion is expanded, and the cylindrical insert can be easily inserted into the finger. Since the opening is formed on the outer end side that intersects the concave arch-shaped notch of the tube, it does not affect the elastic contact function to the side of the finger by the stenosis holding portion, and the phalanx of the cylindrical insertion body It can not work to weaken the fixing force of the joint between the joints, and there is an indexing hole communicating with the inner end side of the slit part, so even if the cylindrical insertion body is repeatedly attached to and detached from the finger Further, the slit portion can be prevented from being further torn.

  Further, in the present invention, ventilation pores that communicate the inside and outside of the tubular insert may be formed on the side wall of the tubular insert.

  With such a configuration, the inner wall of the tubular insert and the outer peripheral portion of the finger are constantly breathing between the atmosphere through the ventilation pores, and can be swollen by inserting the tubular insert of the finger. This prevents the rash from going on, so you can safely work with the tubular insert attached, so there is no sense of discomfort even if you keep using it for a long time. The comfort can always be maintained as it is, and since the vent hole has a small hole shape, the fixing force of the interphalangeal joint portion by the concave wrapping portion is not weakened.

  The present invention configured as described above is encased in a state where the concave envelopment portion is in proximity to or in contact with the raised portion of the osteophyte at the back portion of the interphalangeal joint portion of the finger, and the side portion of the finger is held tightly Since it is elastically held by the part, it can be securely inserted and fixed to the interphalangeal joint while being positioned at a predetermined position of the finger, and as a result, use of the finger after insertion into the finger The joints of the interphalangeal joints should be firmly fixed in a state that fits the shape of the fingers so that the bone spine bulges are always stably encased in place in the concave envelopment part Moreover, since the side portion of the finger is elastically held by the stenosis holding portion during use, it cannot be easily removed from the finger during use.

  In addition, since the cylindrical insert is manufactured as a resin molded body molded using a plaster mold that is manufactured by shaping a finger in the disease, it is the minimum that can fulfill the fixing function of the interphalangeal joint. Therefore, the insertion feeling can be remarkably improved since a large gap is not formed between adjacent fingers.

  Further, the cylindrical insertion body has an end surface at one end side opening end portion opposed to a phalanx portion existing at the distal end side of the interphalangeal joint portion and an end surface at the other end side opening end portion existing on the proximal phalanx side. Since it has a length dimension until it is opposed to the phalanx, the tip of the finger is exposed to the outside, and it is easy to grasp the sensation when an object touches, and it does not cause any disease The interphalangeal joint can be exposed, and the motor function of the other interphalangeal joint is not affected.

  As shown in FIG. 1, Heberden's nodule, which is one of the osteoarthritis of the fingers, is a finger in all or part of the thumb 1a, the index finger 1b, the middle finger 1c, the crown finger 1d and the little finger 1e which are the fingers 1. Internode joints (in the case of the index finger 1b, the middle finger 1c, the crown finger 1d, and the little finger 1e, one or both of the first joint part 2a and the second joint part 2b are collectively referred to, and the thumb 1a In this case, only the first joint portion 2a is present). On the back side of 2, swelling, pain and redness occur, and the osteophyte ridge 3 due to osseous ridge develops, a hard nodule is formed, As shown in the figure, the internode joint part 2 is bent and deformed, causing lateral displacement of the finger 1 and subluxation, and the skin on the back side of the interphalangeal joint part 2 is Thinning and mucinous cysts are formed. When things even a little on the back side of the movement pain and interphalangeal joint unit 2 at the time of use is touching, so that the run is severe pain in the finger 1.

  In order to protect the finger 1 from such pain, it is effective to rest and fix the interphalangeal joint part 2 by inserting a removable finger protection device into the finger 1 which is one of the external fixation methods. Has been.

  Therefore, the finger protection device according to the embodiment of the present invention improves the adaptability to the shape of the finger 1 when the interphalangeal joint 2 is fixed from the outside by simply inserting it into the patient's finger 1. In addition, when the finger 1 is used after being inserted, the interphalangeal joint portion 2 can be securely fixed without moving excessively, and the finger 1 can be easily used during use. It is configured so that it cannot fall out more.

  Next, an embodiment according to the present invention will be described with reference to FIGS.

  That is, as shown in FIGS. 2 to 4, the finger protection device 10 according to the embodiment of the present invention has a circumference of each of the thumb 1 a, the indicating finger 1 b, the middle finger 1 c, the crown finger 1 d, and the little finger 1 e constituting the finger 1. In order to be able to be mounted in a state of being continuously surrounded over, the basic shape is formed from a resin molded body having a substantially circular cross section, and both ends thereof are respectively one end side opening end portion 11a and the other end side opening end portion 11b. It has the cylindrical insertion body 11 which becomes. The resin molded body constituting the cylindrical insert 11 is, for example, when a soft polypropylene (trade name: Trelac or Elcoflex, etc.) containing silicon in PP or a soft polyester touches or bumps. It has a hardness that is difficult to be deformed with respect to a predetermined force applied to the material, but when a deformation force greater than the predetermined force is applied, it is molded using a material that can be elastically deformed. Then, although the situation of the affected part can be easily grasped in the insertion state, if it is made a translucent color having a color such as skin color, it can be enriched in fashion.

  In the tubular insertion body 11, the osteophyte protuberance 3 is close to the inner wall of the site facing the osteophyte protuberance 3 in the dorsal part 2-1 of the interphalangeal joint 2 in the state of being inserted into the finger 1. A concave enveloping portion 13 is formed that is encased in a contact state, and the outer wall facing the concave enveloping portion 13 is convex due to the formation of the concave enveloping portion 13.

  For example, when a Heberden disease occurs in the first joint portion 2a, the tubular insert 11 is attached to the finger 1 so that the concave enveloping portion 13, that is, the back side of the interphalangeal joint portion 2 is disposed. In the middle, the end surface 11a-1 of the one end opening end 11a of the both opening end portions 11a and 11b is connected to the distal node 2c which is a finger segment existing on the distal end side of the finger 1 in the interphalangeal joint portion 2. It is configured to have a length dimension until the end surface 11b-1 of the opening end portion 11b on the other end side opposes the middle phalange portion 2d which is a phalangeal portion existing on the proximal phalanx 2f side. .

  Further, when the Heberden disease occurs in the second joint portion 2b, for example, although not shown, the end surface 11a-1 of the one-end opening end portion 11a of the cylindrical insertion body 11 is located opposite to the middle node portion 2d. At the same time, the end surface 11b-1 of the other-end-side opening end portion 11b is positioned opposite to the proximal portion 2e.

  On one or both inner walls of one end opening end 11a and the other end opening end 11b of the cylindrical insertion body 11, a narrowing holding portion 14 is formed that elastically contacts both side portions 1-1 of the finger 1. ing.

  In this embodiment, the stenosis holding portions 14 are formed in a pair so as to be elastically in contact with opposite side portions 1-1 of the finger 1 at the one end side opening end portion 11a or the other end side opening end portion 11b. Only one of the parts 1-1 may be elastically contacted with only one, and the holding function of the cylindrical insert 11 to the finger 1 may be achieved by pressing the part 1-1 against the other. .

  In the tubular insert 11, a planar portion 15 is formed in a palm side portion 11 c facing the abdomen side of the finger 1.

  In this embodiment, the planar portion 15 is exposed on the inner and outer walls of the cylindrical insert 11, but is not limited to this, and only the inner wall may be formed to be planar. Good.

  For example, when a Heberden disease occurs in the first joint portion 2a, the cylindrical insert body 11 is opposed to the abdomen side and the back side of the distal node portion 2c existing on the distal end side of the finger 1 at the one end side opening end portion 11a. A first concave arch-like cutout portion 16 having a concave arch shape is formed on the other end side opening end portion 11b side, and similarly, the tip of the finger 1 at the other end side opening end portion 11b. On the side facing the abdomen side and back side of the middle node 2d (if the Heberden disease appears on the thumb 1a, it becomes the proximal node 2e), a concave arch on the one end side open end 11a side A second concave arc-shaped notch 17 is formed.

  Although not shown, for example, when a Heberden disease occurs in the second joint portion 2b, the first concave arcuate notch portion 16 is formed at a portion facing the abdomen side and the back side of the middle node portion 2d. Thus, the second concave arcuate notch portion 17 is formed at a portion facing the abdomen side and the back side of the base node 2e.

  Of the pair of second concave arc-shaped notches 17, the outer end side of the cylindrical insert 11 is arranged so as to intersect the second concave arc-shaped notch 17 existing on the back side of the finger 1. An opening slit portion 18 is formed, and an indexing hole 19 that communicates with the inner end side of the slit portion 18 and that indexes the slit portion 18 is formed.

  Further, a plurality of ventilation pores 12 are formed on the side wall of the cylindrical insertion body 11 in a state of being appropriately separated from each other to communicate the inside and the outside.

  Next, the manufacturing method of the cylindrical insertion body 11 comprised as mentioned above is demonstrated.

  First, a cylindrical material for forming the cylindrical insert 11 is preliminarily used by using a resin material such as soft polypropylene (trade name: Trelux or L-flex) containing PP in silicon or soft polyester. , To have a predetermined length.

  At the same time, the diseased finger 1 is coated with a gypsum material and then solidified to produce a female prototype of the finger 1, and then another gypsum material is introduced into the female mold, so that the diseased finger A male mold having the same diameter as 1 is prepared.

  In the male mold after the production, the shape of the molding surface is appropriately corrected in order to make the stenosis holding portion 14 elastically contact the both sides 1-1 of the finger 1.

  Next, while the cylindrical material prepared in advance is heated to a predetermined temperature, it is fitted into the male mold, and the vacuum is used to suck the cylindrical material while maintaining this state. Thus, the cylindrical insert 11 having a shape suitable for the molding surface of the male mold is produced.

  Thus, since the cylindrical insert 11 is composed of a molded body of a resin material, it does not require a shape matching operation to the fingers by cutting out the resin material, and mass-produces products with a constant shape and quality. Will be able to.

  In the embodiment according to the present invention configured as described above, in order to attach the cylindrical insert 11 to the finger 1 having the Heberden disease, the other end side opening end portion 11b, the concave enveloping from the distal end side of the finger 1 is performed. It inserts into the finger | toe 1 in the order of the part 13 and the one end side opening edge part 11a. In such an insertion process, the stenosis holding part 14 is inserted into the finger 1 while being elastically expanded as appropriate in accordance with the shape of the various parts of the finger 1, and is connected to the terminal node 2 c (or the middle node 2 d) of the finger 1. At the stage where the side part of the middle joint part 2d (or the base joint part 2e) has reached a predetermined position, the expansion deformation is released, the side part is elastically contacted, and the concave enveloping part 13 is the first joint part 2a (or The second joint portion 2b) is reached, and the osteophyte bulge portion 3 is wrapped in contact or close to the first joint portion 2a (or the second joint portion 2b) to be fixed.

  Therefore, in the above-described embodiment according to the present invention, the concave enveloping portion 13 is encased in a state where the concave enveloping portion 13 is close to or in contact with the osteophyte bulge portion 3 in the back portion 2-1 of the interphalangeal joint portion 2 in the finger 1. Moreover, since the side portion of the finger 1 is elastically held by the narrowing holding portion 14, the interphalangeal joint portion 2 can be reliably inserted and fixed in a state where the finger 1 is positioned at a predetermined position. As a result, the osteophyte protuberance 3 is always stably encased in a predetermined position in the concave enveloping portion 13 without moving to the flood due to the use of the finger 1 or the like in the inserted state. The interphalangeal joint part 2 can be firmly fixed in a state adapted to the above, and the side part of the finger 1 is elastically held by the stenosis holding part 14 during use. That it cannot fall out of finger 1 Ri, it is possible to acknowledge the very freedom and convenience in the use of the fingers in everyday life. In addition, since the cylindrical insert 11 can be easily attached to and detached from the finger 1, the patient himself / herself can repeat the attachment / detachment of the cylindrical insert 11 many times in daily life, which makes it extremely difficult to treat diseases. It can be performed simply.

  Moreover, since the cylindrical insertion body 11 can be comprised as a resin molded object shape | molded using the gypsum type | mold produced by shaping the finger 1 in the disease, it fulfills the fixing function of the interphalangeal joint part 2. Since it is only necessary to have the minimum wall thickness to be obtained, it can be formed very thin, and a large gap is not formed between adjacent fingers 1, so that the insertion feeling can be significantly improved. .

  Furthermore, the cylindrical insertion body 11 is opposed to the end node portion 2c (or the middle node portion 2d), which is a phalangeal portion where the end surface 11a-1 of the opening end portion 11a on the one end side is on the distal end side of the interphalangeal joint portion 2. And has a length dimension until the end surface 11b-1 of the other end opening end 11b is opposed to the middle segment 2d (or proximal segment 2e) which is a finger segment existing on the proximal phalanx 2f side. Therefore, the tip of the finger 1 is exposed to the outside, so that it is easy to grasp the sense of touching an object, and the other interphalangeal joint 2 that is not diseased can be exposed. Thus, the motor function of the other interphalangeal joint 2 is not affected.

  Further, even if the palm portion 2-2 of the finger 1 is strongly pressed against an object or the like, the flat portion 15 is formed, so that the pressing force pushes the concave enveloping portion 13 outward. Therefore, it is possible to prevent the concave wrapping portion 13 from being largely separated from the osteophyte bulge portion 3 during use, and the inner wall of the cylindrical insert 11 is always the interphalangeal joint portion 2. It is possible to further improve the fixing function of the interphalangeal joint 2 by approaching or abutting the joint.

  Further, with this configuration, even if the finger is used while the tubular insert is attached to the finger, the palm or back of the finger joint side of the phalanx having the open end on the one end is the first concave arch. The presence of the notch is surely exposed so that the sense of touching an object can be easily grasped, the insertion sense can be wiped away, and the first concave bow Since the notch is a concave arch, it does not affect the elastic contact holding function to the side of the finger by the stenosis holding part formed on the opening end side of the one end side, and the interphalangeal joint fixing function Will not deteriorate.

  Further, with this configuration, even if the finger is used while the tubular insert is attached to the finger, the palm or back on the fingertip side of the phalanx portion where the other end side opening end portion exists is the second concave portion. The presence of the arcuate notch ensures that the sensation when an object touches the finger is easier to grasp, and the insertion sensation can be wiped away. Since the arcuate notch is a concave arch, it does not affect the elastic contact holding function to the side of the finger by the stenosis holding part formed on the opening end side of the other end side. The fixed function is not deteriorated.

  Also, with this configuration, when the tubular insert 11 is attached to the finger 1, the slit portion 18 is widened so that the tubular insert 11 can be easily inserted into the finger 1. After that, since the slit portion 18 is formed on the outer end side intersecting with the second concave arc-shaped notch portion 17, the elastic contact function of the stenosis holding portion 14 to the side portion of the finger 1 is affected. In addition, it is impossible to work to weaken the fixing force of the interphalangeal joint portion 2 of the cylindrical insertion body 11, and the presence of the blocking hole 19 communicating with the inner end side of the slit portion 18 makes it possible to form a cylindrical shape. Even if the insertion / removal operation of the insertion body 11 on the finger 1 is repeated, it is possible to prevent the slit portion 18 from further separating.

  Further, with this configuration, the inner wall of the cylindrical insert 11 and the outer peripheral portion of the finger 1 are constantly breathing between the atmosphere through the ventilation pores 12, and the cylindrical insert 11 of the finger 1. It is possible to prevent wiping and rashing by inserting, and water work with the tubular insert 11 attached can be performed with peace of mind, and the ventilation pores 12 are thin. Due to the hole shape of the diameter, the fixing force of the interphalangeal joint portion 2 by the concave enveloping portion 13 is not weakened.

  In the above embodiment, the finger protection device according to the present invention has been described as a treatment device for Heberden's nodule, but is not limited to this, for example, for the treatment of rheumatoid or other finger osteoarthritis. It can also be used as a brace.

  As described above, the present invention improves the external fixation method that can be easily inserted into the patient's finger and can fix the interphalangeal joint from the outside, and is compatible with the shape of the finger. In addition to being improved, it is possible to securely fix the interphalangeal joint part so that it can not move excessively when it is used after it is inserted, and it can be easily detached from the finger during use. In order to treat pain and swelling of interphalangeal joints due to osteoarthritis of the fingers such as Heberden's nodule or rheumatism, etc. It is suitable for a finger protection device.
