<First embodiment>
FIG. 1 is a diagram showing an example of a surgical instrument according to the first embodiment, and is (a) a front view and (b) a cross-sectional view. FIG. 2 is a diagram showing another example. In FIG. 1, X indicates the width direction (horizontal direction, left-right direction), Y indicates the longitudinal direction (longitudinal direction, front-back direction), Z indicates the thickness direction (depth direction, up-down direction) (each figure below) same in). The treatment instrument 1 is a treatment instrument for performing treatment such as stroking, shaking, and hitting a target site on a living body.

The treatment instrument 1 has a treatment section 10 for performing treatment by contacting a target site, and a handle section 40 for operating the treatment section 10 . The treatment unit 10 has one or more finger parts 20 that perform treatment in contact with the target site. As an example, an example having one finger portion 20 will be described here.

The finger portion 20 is formed in a bar shape and includes a core portion 22 and an action portion 21 having flexibility and covering at least a portion of the outer periphery of the core portion 22 . The acting portion 21 is fixed to the core portion 22 by the fixing portion 23 . The fixed portion 23 may be formed by thermal welding, or may be formed by using an adhesive or a pressure-sensitive adhesive. For example, the core portion 22 may be molded from a plastic resin, and an elastomer resin or rubber material may be double-molded and fixed as the action portion 21 around the core portion 22 .

As an example, the acting portion 21 is formed so as to cover a portion of the core portion 22 (for example, 1/2 to 2/3 of the outer circumference). As shown in FIG. 1(b), the action part 21 is formed in, for example, a substantially U-shaped cross section, and the contact surface that contacts the target site is a convex curved surface.

As an example, the acting portion 21 is formed so as to cover the entire outer periphery of the core portion 22 as shown in FIG. For example, as shown in FIG. 2(a), the acting portion 21 has four surfaces, and the contact surfaces are convex curved surfaces. For example, as shown in FIG. 2B, the acting portion 21 is formed in a circular cross-sectional shape, has a uniform thickness, and is concentric with the core portion 22 . For example, as shown in FIG. 2C, the acting portion 21 is formed in a circular cross-sectional shape, has a varying thickness, and is displaced from the center of the core portion 22 .

The acting portion 21 is made of a flexible material, such as so-called silicone, urethane, elastomer, or rubber. A foam material, a gel-like material, artificial leather, or the like may be used. In the case of silicone, the hardness of the material used for the action portion 21 is, for example, 5° to 35°, preferably 8° to 30°, more preferably 10° to 26°. In other words, the action portion 21 is preferably formed with a low hardness of 30° or less. Other materials may be formed to have similar hardness. Note that the hardness range may be appropriately changed according to the material.

Here, the hardness refers to "durometer hardness" which is widely used because the measuring instrument is simple and easy to use. "Durometer hardness" is a method in which a non-sharp needle (push needle, indenter) is pushed into the surface of the object to be measured, and the amount of deformation is measured and quantified, and a spring is used as the force to push the needle. . Standardized in JIS K 6253-3, durometers include type A, type D, type E and type AM, and the selection is as follows.
- If the type D durometer gives a hardness value of less than 20, use type A.
- if the type A durometer gives a hardness value less than 20, use type E;
- If the type A durometer shows a hardness value greater than 90, use type D.
Hardness in the specification and claims herein is a value measured in durometers of the type selected above.

The core part 22 has hardness, and as an example, is formed in a bar shape with a circular cross section as shown in the drawing. The core portion 22 extends in the longitudinal direction of the surgical instrument 1 and connects with the handle portion 40 . The core 22 is made of metal (for example, iron, copper, gold, silver, aluminum, stainless steel, titanium, magnesium, tungsten, or alloys thereof), ore, or resin such as polypropylene, nylon, ABS, or the like.

The treatment section 10 is configured to have a weight of, for example, 10 g to 600 g, preferably 20 g to 500 g, more preferably 30 g to 400 g, so that an appropriate load is applied to the target site. As will be described later, when having a plurality of fingers 20, one finger 20 is, for example, 10g to 300g, preferably 10g to 250g, more preferably 10g to 200g.

In addition, it is also possible to set the amount of the entire load applied during the treatment depending on the target part of the treatment. For example, 10g to 400g for fascia care on the skin surface, 50g to 1kg for muscles and tendons, 200g to 1.5kg for skeletal (ribs, fingers, toes, etc.), skeletal (backbone, limbs, etc.) ) from 400 g to 3 kg for system approaches.

In the treatment instrument 1, the action part 21 has high adhesion to the target site, and it is easy to perform treatment by shaking the target site. During treatment, the handle part 40 is lightly shaken left and right or back and forth with the finger part 20 placed on the target part so as to shake the target part by hand. Then, the target portion in close contact with the action portion 21 is moved and shaken together with the action portion 21 . At this time, an appropriate pressure is applied to the target part by the weight of the finger part 20, and it becomes easy to rock.

In addition, in the surgical instrument 1, the fingers 20 are lifted slightly so that the weight of the fingers 20 is not entirely applied to the target site, and the handle 40 is moved left and right or back and forth to move the fingers 20 left and right on the target site. Alternatively, it is possible to perform a treatment by stroking the target site by sliding it back and forth.

Moreover, the surgical instrument 1 can perform a surgical operation by tapping the target site with the fingers 20 . Since the action part 21 has flexibility, it is possible to transmit the vibration to the deep part while reducing the impact.

In this manner, the treatment instrument 1 has the treatment section 10 configured to be flexible, mimics a human hand or fingers, and can perform treatment efficiently. In addition, the treatment instrument 1 is easy to perform even when the operator is of the opposite sex, and self-care is also easy to perform.

The treatment instrument 1 may be provided with an uneven pattern on the surface of the action portion 21 . More specifically, all or part of the surface of the action portion 21 may be provided with a fine uneven pattern, such as a circular, semicircular, or spiral pattern, or a combination of these patterns. The depth of the unevenness is, for example, 0.1 mm to 1 mm, preferably 0.2 mm to 1 mm. By providing the pattern, it is possible to enhance the adhesion (adsorption) to the target site.

The treatment instrument 1 may have a surface layer or epidermis that covers and protects the action portion 21 . Such a surface layer or epidermis may be made of the same material as the action portion 21, or may be made of a different material. Materials that differ only in hardness may be used. Techniques such as overmolding, coating, and winding may be used to form the surface layer or skin portion. Further, the surface layer or skin portion may be provided with the uneven pattern as described above.

As for the surgical instrument 1, the whole action part 21 may adhere to the core part 22, and only one part may adhere. For example, only the vicinity of both sides of the core part 22 may be fixed, so that the slack in the vicinity of the middle may enhance the adhesion to the skin during treatment.

<Second embodiment>
FIG. 3 is a view showing an example of the surgical instrument according to the second embodiment, (a) a front view and (b) a side view. FIG. 4 is a diagram for explaining how it is used. Differences from the above embodiment will be mainly described below. The treatment section 10 of this embodiment has a plurality of finger sections and is connected to the handle section 40 via the connection section 30 . An example of five fingers will be described below, but the number of fingers may be 22 to 4, or may be 6 or more.

As an example, the treatment section 10 has five fingers, finger 20a, finger 20b, finger 20c, finger 20d, and finger 20e, as shown. These fingers extend longitudinally with a predetermined gap between them. The five finger parts are connected in parallel by the finger connecting part and are integrated. Here, two connecting portions, the first finger connecting portion 13 and the second finger connecting portion 14, are connected by inserting five finger portions in a skewed manner. More specifically, the second finger connecting portion 14 is inserted through the rear portion of each finger, and the first finger connecting portion 13 is inserted through each finger slightly forward of the second finger connecting portion 14. , connecting five fingers.

The connection part 30 has a front stage part 31 connected to the treatment part 10 , a middle stage part 32 thicker than the front stage part 31 , and a rear stage part 33 thicker than the middle stage part 32 . These may be made of the same material or may be made of different materials. Preferably, the front section 31 is flexible and bends. The middle section 32 may also be configured to have flexibility and bend.

The illustrated surgical instrument 1 is configured in a rod shape continuously from the front stage portion 31 to the rear stage portion 33 and further to the handle portion 40. However, it may be configured in parallel two or more rod shapes. , may be configured in a flat plate shape. In addition, although it extends linearly in the drawing, it bends into a curved shape, a U-shape, or the like, and a step is formed between the treatment section 10 and the treatment section 10 so that it is positioned above the treatment section 10 during treatment. may be Also, the linear state may be changed to another shape.

FIG. 4 shows an example of mainly shaking the skin surface, for example, fascia care for promoting the flow of blood and lymph around the skin and fascia. As shown in (1) of FIG. 4, when the treatment section 10 is placed on the target site O (specifically, the skin), the target site O is depressed due to its weight. More specifically, the target portion O is recessed at the lower portion of the finger portion and protrudes on both sides thereof. For convenience, only the finger portions 20b, 20c, and 20d are shown here, and other portions are omitted.

As shown in (2) of FIG. 4, when the treatment section 10 moves in the direction of the arrow, the target site O in close contact with each finger is gradually pulled in the direction of the arrow (leftward) in the figure. Also, since the acting portion of each finger has flexibility, it is deformed so that the forward portion in the moving direction is recessed (thinner) and the rearward portion is protruded (thickened). In addition, the stress of the acting portion (the arrow in the drawing) attempts to restore the target portion O to its original state. This force increases the leftward pulling force with respect to the target site O, but a gentle (gentle) pulling force (horizontal direction pressure) is applied (occurred) due to the flexibility of the action portion. When the treatment unit 10 moves rightward in the figure from this position, the leftward pulling force is gradually weakened, and the pulling force returns to the state shown in FIG. 4(1). Also in this process, a gentle, pulling force cancellation occurs due to the flexibility of the working part. Next, the treatment section moves to the right in the drawing, thereby shifting to the state shown in FIG. 4(3). As shown in (3) of FIG. 4, even when moving in the opposite direction, a gentle force change occurs due to the flexibility of the acting portion. In this manner, a gentle force is applied to the target site without being greatly affected by the movement of the person who operates the handle, so that the treatment can be performed without giving tension to the body.

Further, at this time, the treatment effect is enhanced by holding the swing width of the treatment section 10 within a range in which the treatment section 10 does not slip on the target site. Therefore, a mechanism for limiting or adjusting the amplitude of the treatment section 10 may be provided. The amplitude is 5 mm to 60 mm, preferably 5 mm to 50 mm, more preferably 5 mm to 40 mm.

It is said that the human body has a mechanism in which the skin and muscles detect danger and contract when strong force or sudden pressure is applied. An extreme example is whiplash. It is said that the sarcoplasmic reticulum is damaged when an excessive load is applied to the muscle fibers, and calcium ions are released from the sarcoplasmic reticulum to the sarcoplasm even if no action potential is generated. As a result, the thin filaments slip between the thick filaments, shortening the muscle fibers, and at this time action potentials do not occur, so they are called contractures, not contractions. It is said that when contracture occurs, blood flow is disturbed, and in addition to this, energy consumption increases due to contracture, metabolites accumulate, and bradykinin is produced, causing pain. At this time, prostaglandins are also produced, and the pain-producing action of bradykinin increases. When muscles become the source of pain, reflex muscle contraction and vasoconstriction are added to intensify pain, and it is said that a vicious circle of pain is created. there is

As described above, the treatment instrument 1 moves (swings) in a direction orthogonal to the extending direction of the plurality of fingers by swinging the handle portion left and right by a predetermined width. A treatment can be performed by gently pressing and shaking the target site O with the fingers.

If the action portion is hard, it will not fit well with the target site O, causing the target site O to wrinkle, slipping on the target site O, and the like, thereby impairing the effect of the treatment. On the other hand, if it is composed only of a flexible material and does not have a hard core, it is difficult to apply a uniform pressure, making it difficult to move the fingers as desired.

<Third Embodiment>
FIG. 5 is a diagram showing an example of a surgical instrument according to the third embodiment, and is (a) a front view and (b) a side view. FIG. 6 is a diagram for explaining the finger portion. 7A and 7B are diagrams for explaining the treatment part, (a) initial state, (b) plan view of target site and contact state, (c) side view of target site and contact state, (e) target site and It is a bottom view of a contact state. Differences from the above embodiment will be mainly described below. In the surgical instrument 1 of this embodiment, the fingers of the surgical section 10 have joints.

The treatment section 10 has five fingers, each finger has a plurality of core members, and the core members are movably connected to each other by joints. The first finger portion 20a and the fifth finger portion 20e on both sides in the left-right direction are formed substantially line symmetrically, and here, the first finger portion 20a will be described as an example. As an example, in the first finger portion 20a, the core portion 22a has three rod-shaped core members, namely, a first core member 221a, a second core member 222a and a third core member 223a. The core member 222a is movably connected by a first joint, and the second core member 222a and the third core member 223a are movably connected by a second joint. Preferably, the third core member 223a is bent laterally inward (toward the second finger portion 20b) at an obtuse angle in the vicinity of the distal end, and is bent in the longitudinal direction in the vicinity of the proximal end and folded back. The fifth finger portion 20e may be formed slightly longer than the first finger portion 20a.

Preferably, the working portion of each finger is provided with a concave knuckle corresponding to the articulation of the core. Each finger has at least a first articulated portion and a corresponding knuckle portion between the first core member and the second core member. Taking the fifth finger portion 20e as an example, as an example, the fifth finger portion 20e has a concave joint portion 2101e that is concave inward in the radial direction corresponding to the first joint portion. By providing the knuckles on the fingers, the joints can be moved more easily.

The intermediate second finger portion 20b, third finger portion 20c and fourth finger portion 20d are formed in substantially the same shape except for the length. It should be noted that the lengths may be equal, but preferably as shown. The third finger 20c is longer than the others. Taking the third finger portion 20c as an example, as an example, the core portion 22c has four rod-shaped core members, and adjacent core members are movably connected by joint portions.

Here, the core member will be described more specifically. Each core member is formed in a plate-like shape with a reduced width at the base end, and is provided with a hole penetrating through the thickness of the plate. Each of the core members other than the first core member has a rear recessed groove at the center of the distal end portion, and laterally penetrating holes are provided in the walls on both sides of the groove. The proximal end of each core member is inserted into the groove of the distal end of the adjacent core member, and jointly passed through a shaft member described later to be connected.
In the example shown here, adjacent core members are connected by shaft members. However, the present invention is not limited to this, and the tips of the core members may be connected with wires by welding, caulking, adhesion, screwing, or the like so that each finger can be bent at each joint. In addition, by wrapping each core member and between each core member with the action portion 21 instead of connecting the core members directly, each core member is indirectly connected and each finger can be bent at each joint. may

As shown in FIG. 6, in the third finger portion 20c, a first core member 221c and a second core member 222c are rotatably connected by a shaft member 2201c, and a second core member 222c and a third core member 223c are connected as shafts. It is rotatably connected by member 2202c.

In the third finger portion 20c, the third core member 223c and the fourth core member 224c are rotatably connected by the shaft member 1101. As shown in FIG. As shown in FIG. 5(a), the shaft member 1101 is a common pivot shaft for the second finger portion 20b, the third finger portion 20c and the fourth finger portion 20d and integrally connects them. 5A, the shaft member 1102 through which the proximal ends of the rearmost core members of the five fingers including the first finger 20a and the fifth finger 20e are inserted, the common pivot of the parts and connects them together. Preferably, the peripheral working portions of the common shaft member are joined together next to each other to form the palm portion 11 .

The treatment connection part 311 of the front stage part 31 of the connection part 30 is formed in a substantially U shape, and both ends extending in the front-rear direction are inserted by the shaft members 1101 and 1102 so that the treatment part is rotatable within a predetermined angle. support. Moreover, preferably, the front stage portion 31 has flexibility, and is bent by the weight of the treatment portion 10 itself.

Moreover, although not shown, a spring member (for example, a torsion spring, a leaf spring, or a coil spring) may be provided on the shaft portion of each shaft member to suppress the bending amount. Furthermore, the spring members may be combined so that the contact surface with the target site is a curved surface. Also, a latch may be provided on the shaft member, and combined with the strength of the spring of the latch, a fixed angle may be held and fixed with a predetermined strength, so that the angle of each finger may be changed.

Since the core of the fingers of the treatment section 10 has joints, when the treatment section 10 in the initial state shown in FIG. The shape conforms to the surface shape. For example, when the target site O is a convex curved surface, each finger portion is shaped along the convex curved surface of the target site O as shown in FIGS. 7B, 7C, and 7D. bends and comes into intimate contact with the target site O. In addition, since the operating portion of the finger portion of the treatment portion 10 has a concave knot portion, the joint portion can be more easily moved.
As a result, even if the target site O is a convex curved surface (spherical surface) such as a shoulder, elbow, heel, or head, it is possible to perform a treatment such as shaking or stroking by closely contacting the target site. It can enhance the effect of surgery. In addition, even if the target part O is a cylindrical part such as an arm or a leg, or a semi-cylindrical part such as the side of the abdomen, the treatment is performed along the shape of the part, and a high treatment effect can be obtained. can get.

Preferably, in the treatment section 10, the spacing between adjacent finger sections can be adjusted. As an example, as shown in FIG. 8(a), the first finger portion 20a and the fifth finger portion 20e are moved outward to widen the distance between the adjacent finger portions and widen the width of the treatment portion 10 as a whole. may As a result, a wide range of treatments can be performed efficiently. Further, for example, as shown in FIGS. 8(b) and 8(c), it becomes easier to perform the treatment using the middle three fingers.

The treatment section 10 may have a finger movement mechanism for individually moving the fingers. As an example, the treatment section 10 has a tendon member configured to pull the core member of the finger, and as shown in FIG. By pulling it in a direction and bending it, you may make it operate|move with the remaining finger|toe part. As another example, a tendon member may bend some fingers in the direction of the target site O so as not to contact the target site O. FIG. Further, the finger part that performs the treatment on the target site O may be moved by the tendon member to change the shape or the operation to perform the treatment.

In this manner, the treatment instrument 1 can perform treatment in accordance with the target site to be treated, the purpose of the treatment, etc., by changing the mode of contact and close contact.

18A and 18B are diagrams showing another example of the surgical instrument according to the third embodiment, and are (a) a front view and (b) a side view. The treatment instrument 1 may further include a contact portion 81 , and the treatment may be performed so that the treatment portion 10 swings while being supported by the contact portion 81 .
The contact portion 81 has a side contact portion 811 , a contact arm portion 812 and a position adjusting portion 813 . The side contact part 811 is provided beside the treatment part 10 at a predetermined interval. As an example, the position adjustment part 813 is attached to the rear part 33 of the connection part 30 and fixed to the connection part 30 with a screw 8131 . The contact arm portion 812 is a portion extending between the side contact portion 811 and the position adjustment portion 813 .
The position of the contact portion 81 can be adjusted by loosening the screw 8131 and adjusting the position of the position adjusting portion 813 . The backing arm 812 may be made of a deformable material and relatively adjusted by bending the backing arm 812 into a predetermined shape. A latch mechanism may be provided in the abutting portion 81 , and the position or the distance from the treatment portion 10 may be adjusted by this or in conjunction therewith.
The side contact portion 811 may be in contact with or held by the operator or his/her attachment, may be in contact with or held by the non-operator or his/her attachment, or may be a treatment bed, chair, or It may be one that abuts on or is held by a peripheral member or the like. In addition, such a contact part may be provided in the surgical instrument of another embodiment.

<Fourth Embodiment>
FIG. 9 is a diagram showing an example of a surgical instrument according to the fourth embodiment, (a) showing one example, and (b) showing another example. Differences from the above embodiment will be mainly described below. The treatment instrument 1 of this embodiment has a moving mechanism that moves the treatment section 10 integrally on the target site.

The movement mechanism includes, for example, a pull portion 41 , a front stage portion 31 and a compression coil spring 71 . The pull part 41 is arranged on the handle part 40 so that it can be pulled rearward. Here, the handle portion 40 is formed in a substantially rectangular frame shape, and the pull portion 41 is arranged so as to traverse the handle portion 40 . The pulling part 41 is an elongated member elongated in the lateral direction, and has four recesses corresponding to four fingers so that the front surface of the pulling part 41 can be easily hooked.

The front step portion 31 includes a middle step portion 32 and a rear step portion 33 formed in a cylindrical shape. In other words, the front stage portion 31 extends to the handle portion 40 , is inserted through a through hole provided in the front frame of the handle portion 40 , and is connected to the pull portion 41 .

The compression coil spring 71 is fitted to the exposed portion of the front step portion 31 . More specifically, the front stage portion 31 is provided with an expansion portion 312 that expands in the radial direction near the base end portion of the treatment portion 10 . At least the rear end of the expansion portion 312 is thicker than the other portions of the front step portion 31 . The compression coil spring 71 is fitted between the expanded portion 312 and the intermediate step portion 32 so that the front step portion 31 is inserted through the inner side thereof.

As shown in FIG. 9( a ), when the pulling portion 41 is pulled in the direction of the arrow, the treatment portion 10 retreats in the direction of the arrow. When the pulling portion 41 is loosened, the treatment portion 10 is returned forward by the compression coil spring 71 . In this manner, by providing the movement mechanism, the treatment instrument 1 can perform treatment such as stroking or gently rubbing the target site by moving only the treatment part in the front-rear direction, in addition to the above treatment.

As an example, the treatment section 10 is arranged such that the fingers extend in the front-rear direction as shown in FIG. 9A, as in the second embodiment (FIG. 3). As an example, as shown in FIG. 9B, the treatment section 10 may be arranged such that the fingers extend in the left-right direction (horizontal direction) and intersect the longitudinal direction. A finger connecting portion that connects a plurality of finger portions in a skewed manner may be composed of three finger connecting portions: a first finger connecting portion 13 , a second finger connecting portion 14 and a third finger connecting portion 16 .

A mechanism for rotating the treatment section 10 is not particularly limited, and a conventional technique may be used as appropriate. For example, a structure in which rotation is stopped by a latch may be used.

<Fifth Embodiment>
FIG. 10 is a diagram showing an example of a surgical instrument according to the fifth embodiment. Differences from the above embodiment will be mainly described below. The treatment instrument 1 of this embodiment includes an additional treatment section 50 that performs treatment together with the treatment section 10 . The treatment section 10 is formed in the same manner as the treatment section in any one of the above embodiments, and as an example, is formed in the same manner as in the third embodiment (FIG. 5).

The additional treatment section 50 is formed in the same manner as the treatment section 10, for example. Preferably, the treatment instrument 1 has a movement mechanism for moving the additional treatment section 50 with respect to the treatment section 10 . The movement mechanism includes, for example, the connection shaft 34 , the handle portion 40 , the additional connection portion 60 , the torsion coil spring 72 and the torsion coil spring 73 . This moving mechanism allows the additional treatment section 50 to slide on the treatment section 10 .

At this time, the treatment effect is enhanced when the amplitude of the treatment section 10 is held within a range in which the treatment section 10 does not slip on the target site. Therefore, a mechanism that can limit or adjust the amplitude of the treatment section 10 may be provided. The amplitude is 5 mm to 60 mm, preferably 5 mm to 50 mm, more preferably 5 mm to 40 mm.

The connecting portion 30 is provided with a connecting shaft 34 for connecting with the additional connecting portion 60 . A coil of a torsion coil spring 73 is fitted to the connection shaft 34 . One arm of the torsion coil spring 73 is arranged on the connection portion 30 so as to extend rearward, and the other arm is arranged on a first additional connection portion 61 which will be described later.

The handle portion 40 is bifurcated into a first handle and a second handle at the rear portion of the tip portion. The coil of the torsion coil spring 72 is arranged at the tip of the handle portion 40, and both arms are arranged on the first handle and the second handle, respectively. Due to the repulsive force of the torsion coil spring 72, the handle portion 40 can be opened and closed by bringing the first handle and the second handle closer together or separating them.

The additional connection section 60 has a first additional connection section 61 that connects the additional treatment section 50 and the connection section 30 , and a second additional connection section 62 that connects the first additional connection section 61 and the handle section 40 .

The first additional connection part 61 is provided with a hole near the base end, and this hole and the connection shaft 34 are fitted to connect the additional treatment part 50 to the connection part 30 so as to be rotatable. . The base end of the first additional connection portion 61 is bifurcated into a first base end and a second base end. One end of 62 is fixed. The second additional connection portion 62 extends to the other handle via one handle of the handle portion 40 and is fixed at the other end.

The treatment instrument 1 preferably has the connecting portion 30 curved or bent outward (in the direction away from the additional treatment portion 50), and the first additional connection portion 61 curved or bent outward (in the direction away from the treatment portion 10). , the distance between the treatment section 10 and the additional treatment section 50 is widened. Moreover, preferably, the additional treatment section 50 is arranged so as to cross the treatment section 10 .

During treatment, first, the treatment instrument 1 is placed on the target site O as shown in (1) in FIG. 10 . As shown in (2), when the handle portion 40 is gripped and closed in the direction of the arrow, the second additional connection portion 62 loosens, the torsion coil spring 73 twists in the direction of the arrow, and the additional treatment portion 50 retreats in the direction of the arrow. It slides and moves. As shown in (3), when the handle portion 40 is loosened, the second additional connection portion 62 returns to its original state, the torsion coil spring 73 opens, and the additional treatment portion 50 slides forward in the direction of the arrow. do.

In this way, the surgical instrument 1 can perform more complicated surgical procedures in addition to the surgical procedures described above by including the additional surgical section. As an example, a movement mechanism for slidingly moving the additional treatment section is provided on the treatment section, so that a treatment can be performed by placing both hands of a person on top of each other.

Note that the treatment section of this embodiment may have a configuration different from that of the above embodiment. As an example, the finger portion of the treatment portion may be composed only of the action portion without the core portion. As an example, the treatment section may be composed of a flexible plate-like member having a wide contact surface (flat surface, curved surface, etc.) instead of the rod-like finger portion. The additional treatment section may be formed in the same manner as the treatment section, or may have a different configuration. Further, the handle portion may operate both the treatment portion and the additional treatment portion as described above, or may operate only one of them. That is, the treatment section and the additional treatment section may be operated by separate handle sections.

As an example of the treatment here, the treatment section 10 is placed on a target site (for example, skin), and the additional treatment section 50 placed thereon is shaken (swayed) so that the additional treatment section 50 is moved to the treatment site. 10 is shaken, and the treatment section 10 shakes the target site. This indirect movement provides a gentler, smoother and gentler movement than the movement of directly shaking the treated area, resulting in a more body-friendly treatment. For example, it is said that the shaking pressure in fascia care for the skin is usually around 20 g. Here, for example, 10 g to 100 g.

Further, at this time, the effect of the treatment is enhanced when the swing width of the additional treatment portion 50 is held within a range in which the treatment portion 10 does not slip on the target site. Therefore, the deflection width is set to 5 mm to 60 mm, preferably 5 mm to 50 mm. Also, the amplitude may be adjusted within this range.
