JP6942328B2 - Examination table for self-propelled capsule endoscope - Google Patents

Description

The present invention relates to an examination table for a self-propelled capsule endoscope provided with a magnetic field generating unit for controlling the self-propelled capsule endoscope from outside the body.

Capsule endoscopy is being studied as a method for examining the inside of digestive organs such as the esophagus and gastrointestinal tract. Unlike conventional endoscopes, capsule endoscopes do not require a tube for operating the camera to be passed through the subject's throat, so that the burden on the subject can be significantly reduced. In the capsule endoscopy that has been studied so far, a subject swallows a capsule with a built-in camera, and the capsule moves in the body by the movement of the digestive organ itself such as peristalsis to photograph the inside of the digestive organ.
However, in the movement by peristalsis, it takes a long time to move the capsule endoscope. In addition, since the capsule endoscope cannot be stopped at an arbitrary point by moving by peristalsis, it is not possible to cope with the case where it is desired to observe a specific place in detail. Furthermore, in a digestive organ having a relatively large space such as the stomach, the capsule endoscope moves due to peristalsis, and it is difficult to observe the entire inside in detail. Therefore, when performing a gastric examination and an examination of other digestive organs, there is no choice but to use a capsule endoscopy examination and another examination method in combination, which causes a problem that the labor of the examination increases.

Therefore, in recent years, self-propelled capsule endoscopes have been attracting attention. The self-propelled capsule endoscope is a capsule endoscope provided with a means of transportation such as fins. After the subject swallows the self-propelled capsule endoscope or inserts it through the anus, the capsule endoscope can be freely moved by controlling the moving means from outside the body. Patent Document 1 relates to the invention of a self-propelled capsule endoscope newly disclosed by the present inventor. In Patent Document 1, a fin equipped with a magnet is attached to a capsule endoscope, and after the subject swallows the self-propelled capsule endoscope or inserts it through the anus, a magnetic field is radiated to the subject lying on the examination table. Discloses a technology that can control a self-propelled capsule endoscope inside a subject from outside the body.

WO2015 / 181993

Since the self-propelled capsule endoscope can examine a plurality of organs by a single examination method, the patient's restraint time is relatively long as compared with the case where only one organ is examined. Subjects undergoing examination with a self-propelled capsule endoscope must maintain the same posture for a long time on the examination table, and often feel a physical burden.
Therefore, there has been a demand for an examination table for a self-propelled capsule endoscope that can reduce the burden on the subject by maintaining the same posture for a long time.

1. 1. Base 2
The base portion 2 is a portion that supports the gantry portion 3, the coil portion 4, and the like. As shown in FIGS. 2A and 2B, the base portion 2 is formed from a base main body 2a for fixing the gantry 3 and rotatably connecting the coil portion 4 and a base main body 2a. The base auxiliary portion 2b, which has a low height and a small area, is connected in series. The base auxiliary portion 2b has a height such that the lower portion of the coil portion 4 can be accommodated when the coil portion 4 and the backrest portion 5 described later are in a horizontal state. The base auxiliary portion 2b is not always necessary, but when it is connected to the base main body 2a, the following effects can be obtained. As will be described later, the weight of the very heavy coil portion 4 and the weight applied to the backrest portion 5 when the subject lies down are applied to the base main body portion 2a. In such a case, the presence of the base auxiliary portion 2b can prevent the examination table 1 from tipping over and enhance the stability of the examination table 1. The sizes of the base main body 2a and the base auxiliary 2b can be appropriately changed depending on various conditions such as the installation location of the examination table 1, the size of the coil 4, and whether or not the footrest 7 described later is provided. be.

The base portion 2 is assembled using many frames 21 as shown in FIGS. 2 (a) and 2 (b). The frame 21 can be manufactured from a non-magnetic metal material such as aluminum and stainless steel or a non-metal material such as Grice fiber. It is more preferable to select aluminum in order to reduce the weight of the examination table 1 as much as possible. Each frame 21 is connected and assembled by a conventional general fixing means such as a screw.

A coil connecting portion 22 for rotatably connecting the coil portion 4 is provided on the upper surface of the base main body portion 2a. Two coil connecting portions 22 are provided on the upper surface of the base main body portion 2a, preferably facing each other. As shown in FIGS. 2C to 2E, the coil connecting portion 22 includes a connecting main body portion 22a of the coil connecting portion 22 and an L-shaped pedestal portion 22c attached to the connecting main body portion 22a. The connecting main body 22a is provided with a screw through hole 22b, and the pedestal 22c is provided with a screw hole 22d. The coil connecting portion 22 is fixed to the frame 21 by a fixing means such as a screw via a screw hole 22d at an arbitrary position on the upper surface of the base main body portion 2a, preferably a position as close to the base auxiliary portion 2b as possible. The screw through hole 22b provided in the connecting main body portion 22a of the coil connecting portion 22 is a fixing means used when connecting to the screw through hole 44 of the coil portion 4, which will be described later, for example, a hole for passing a bolt.

The base portion 2 may have a support leg portion 23 on the lower surface thereof, if necessary. Further, the periphery of the base portion 2 can be covered with a panel or the like (not shown).

The gantry portion 3 is a pedestal for supporting the lower body of the subject. The gantry portion 3 is, for example, flat and is provided on the upper surface of the base portion 2 at a substantially horizontal position. The gantry portion 3 is, for example, a plate having a rectangular shape having a longitudinal direction of about 100 cm and having screw through holes. The gantry portion 3 is screwed to the upper surface of the base base main body portion 2a of the base portion 2 through the screw through holes.

3. 3. Coil part 4
The coil unit 4 is a magnetic field generating unit that radiates a magnetic field for controlling the self-propelled capsule endoscope taken into the body of the subject from outside the body to the subject. The coil portion 4 has a hollow portion. The hollow portion is a space in which the upper body of the subject is housed, as will be described later. The coil portion 4 is rotatably connected to the base portion 2 so that the inclination angle can be changed. The shape of the coil portion 4 is not particularly limited as long as it has a hollow portion. The shape of the coil portion 4 may be, for example, a polygonal cylinder such as a triangle, a quadrangle (see, for example, FIG. 3A), a pentagon or a hexagon, or a cylindrical or elliptical cylinder. good. Further, the shape is not limited to the cylindrical shape, and the coil and the coil may be connected by a rod-shaped support member. Hereinafter, the coil portion 4 will be described in detail by taking the square cylindrical coil portion 4 as an example (see FIG. 3A).
The coil portion 4 can include a coil for generating a magnetic field of 1 to 3 axes. Hereinafter, the structure and assembly method of the coil portion 4 will be described by taking a coil portion 4 having a coil for generating a three-axis magnetic field as an example.

As shown in FIG. 3B, the coil portion 4 includes a coil that surrounds the inside of the coil from three directions orthogonal to each other, that is, an x-axis coil 4x and 4x'that generate magnetism in the x-axis direction, and a y-axis. It includes y-axis coils 4y and 4y'that generate directional magnetism and z-axis coils 4z and 4z' that generate z-axis direction magnetism. The coil portion 4 is such that these coils can surround the subject, and the subject swallows a self-propelled capsule endoscope through the mouth or inserts it through the anus, and is located in three directions orthogonal to each other, that is, on six surfaces. The inside of the body is inspected by controlling the progress of the self-propelled capsule endoscope inside the body by the magnetic field from the coil.

Since each coil is a coil for generating a magnetic field, an iron core as used in an electromagnet is not used. Each coil is manufactured by winding a plurality of conductors in a circumferential shape and hardening them with tape, resin, or the like.
In each coil, a circumferential coil with multiple conductors wound is installed coaxially and in parallel with a distance R'same as the radius R so as to generate a uniform magnetic field on the central axis. preferable. However, as described above, since each coil is manufactured by winding metal conductors in multiple directions, each coil is very heavy. Therefore, if each coil is made as small as possible, the weight of the coil portion 4 can be made lighter, and therefore the size of the examination table 1 can be made smaller. On the other hand, as will be described later, the subject is passed through the hollow portion of the coil portion 4, and the self-propelled capsule endoscope is controlled by the magnetic field generated by the coil portion 4. The size of the hollow portion of the coil portion 4 is preferably a size that allows the human body to pass through. Therefore, for example, the x-axis coils 4x and 4x'are set to a size that allows the human body to pass through, and the y-axis coils 4y and 4y'and the z-axis coils 4z and 4z' are set to the sizes of the x-axis coils 4x and 4x'. , It is preferable that the size is set so as to be separated by a distance of half (1 / 2R) of the radius R of the x-axis coil.

The coil portion 4 is manufactured by combining an x-axis coil 4x, 4x', a y-axis coil 4y, 4y', and a z-axis coil 4z, 4z'. Each coil is combined, for example, as follows.

Next, the frame members 43za and 43zb are fixed to the base beam member 41x, and the frame members 43ya are fixed to the connecting beam member 42x with screws or the like. The frame member 43ya has a screw through hole 44 that is connected to the coil connecting portion 22 of the base portion 2 by using a bolt or the like. Next, as shown in FIG. 4B, the x-axis coil 4x is placed on the base made. Subsequently, the y-axis coil 4y and the z-axis coil 4z are placed on the x-axis coil 4x placed on the base. The y-axis coil 4y and the frame member 43ya are fixed with screws or the like. The z-axis coil 4z and the frame members 43za and 43zb are fixed with screws or the like. Next, as shown in FIG. 4C, the frame member 43y'a is fixed to the connecting beam member 42x with screws or the like. The frame member 43y'a has a screw through hole 44 that is connected to the coil connecting portion 22 of the base portion 2 by using a bolt or the like. Then, the y-axis coil 4y'and the z-axis coil 4z' are placed on the x-axis coil 4x. The y-axis coil 4y'and the frame member 43y'a are fixed with screws or the like.

Next, as shown in FIG. 4D, the x-axis coil 4x'is placed on the y-axis coil 4y, 4y'and the z-axis coil 4z, 4z'. On the x-axis coil 4x', the base beam member 41x'and the connecting beam member 42x' are assembled with screws or the like. Next, as shown in FIG. 4E, the frame members 43ya, 43y'a, 43za and 43zb are fixed to the base beam member 41x'and the connecting beam member 42x', respectively, using screws or the like. Next, the frame members 43yb, 43y'b, 43z'a and 43z'b are fixed to the base beam members 41x and 41x'and the connecting beam members 42x and 42x', respectively, using screws or the like. The y-axis coil 4y and the frame member 43yb are fixed with screws or the like. The y-axis coil 4y'and the frame member 43y'b are fixed with screws or the like. The z-axis coil 4z'and the frame members 43z'a and 43z'b are fixed with screws or the like.

Next, as shown in FIG. 5, the pressing blocks 45y, 45y', 45z and 45z' are fixed to the inside of each frame member 43, and the y-axis coils 4y, 4y'and the z-axis coils 4z, 4z' are twisted. It is firmly fixed to each frame member 43. Then, as shown in FIG. 6, the inner plates 46y, 46y', 46z and 46z' are attached to each holding block 45 using screws or the like. As will be described later, the backrest portion 5 is fixed to the edge portion forming the hollow portion of the coil portion 4. For example, a screw hole for fixing the backrest portion 5 can be provided in the inner plate 46z.

After assembling, the coil portion 4 is screwed and connected to the screw through hole 44 and the screw through hole 22b of the coil connecting portion 22 provided in the base portion 2 through a bolt or the like.

As will be described later, when the angle adjusting mechanism 6 is rotatably connected to the coil portion 4, for example, a connecting member 47 for connecting to one end of the angle adjusting mechanism 6 is attached to the frame member 43ya. (See FIG. 7 (a)). Further, the coil portion 4 may be covered with a cover 48 (see FIG. 7B).

4. Backrest 5
The backrest portion 5 has a frame portion 51 whose outer shell is assembled in a rectangular shape by a frame as shown in FIG. 8 (a), and a plate 52 as shown in FIG. 8 (b) having substantially the same shape as the outer shell, which is screwed or the like. It can be assembled by fixing it with the fixing means of. In this case, it is located in substantially the same plane as the above-mentioned gantry portion 3 and is in a horizontal state, and in that state, the upper surfaces of both are substantially flush with each other. Further, since the backrest portion 5 changes the inclination angle together with the coil portion 4, an appropriate gap is provided between the backrest portion 5 and the gantry portion 3. The backrest portion 5 can be, for example, about 100 cm in the longitudinal direction. The backrest portion 5 is fixed to the edge portion forming the hollow portion of the coil portion 4, specifically, the inner plate 46z of the coil portion 4 by using a fixing means such as a screw. The fixing method is not particularly limited. For example, the frame portion 51 is first fixed to the inner plate 46z of the coil portion 4 using a fixing means such as a screw (see FIG. 9A), and then the plate 52 is attached to the frame portion 51. It may be pasted (see FIG. 9B).

5. Angle adjustment mechanism 6
As described above, the angle adjusting mechanism 6 is provided on the base portion 2 and is a mechanism for adjusting the inclination angle of the coil portion 4 and the backrest portion 5 by rotating the coil portion 4 according to expansion and contraction. As the angle adjusting mechanism 6, a general mechanism conventionally used in a chair or bed having a reclining system, for example, a spring, a hydraulic cylinder, a gas spring, or the like can be used. Among these mechanisms, it is preferable to use a gas spring. By using the gas spring, not only the angle adjusting mechanism 6 can be made as small and light as possible, but also the angles of the coil portion 4 and the backrest portion 5 can be changed more freely. Hereinafter, in each drawing, the angle adjusting mechanism 6 is represented by a gas spring. Hereinafter, the angle adjusting mechanism 6 will be described using the gas spring 61 as an example.

As shown in FIG. 10A, the gas spring 61 has a main body tube 61a, a piston rod 61b inserted into the main body tube 61a, and tip portions 61c and 61d provided on the main body tube 61a and the piston rod 61b, respectively. .. A push pin 61e is provided inside the tip portion 61d on the piston rod 61b side. By pushing the push pin 61e, a gas reaction force acts, the piston rod 61b is pushed out from the main body tube 61a, and the gas spring 61 extends. By pushing the piston rod 61b into the main body tube 61a, the gas spring 61 is shortened.

As described above, the gas spring 61 is fixed to the base portion 2. When fixing the gas spring 61 to the base portion 2, the mounting fixing portion 62 as shown in FIGS. 10 (b) to 10 (d) is used. The mounting fixing portion 62 is provided with a substantially trapezoidal mounting main body portion 621 and a pusher 622 that is rotatably attached to the mounting main body portion 621 and can press or release the push pin 61e by rotating the mounting main body portion 62.

Further, a button pressing portion 622a of the pusher 622 is provided in the gap. The button pressing portion 622a is connected to a rotating portion 622b provided on the outside of the plate 621a, and when the rotating portion 622b rotates, the button pressing portion 622a also rotates. FIG. 11 shows a form in which the gas spring 61 and the mounting / fixing portion 62 are assembled.

The tip portion 61c of the gas spring 61 is connected to the coil portion 4 and / or the backrest portion 5 with screws or the like, and the mounting fixing portion 62 is fixed to the base portion 2 with screws or the like. As described above, the inclination angle of the coil portion 4 and the backrest portion 5 is adjusted by expanding and contracting the gas spring 61.
Further, as described above, the coil portion 4 is very heavy because it includes a coil manufactured by winding a plurality of conductors. By fixing the tip portion 61c of the gas spring 61 to the connecting member 47 of the coil portion 4, the extremely heavy coil portion 4 is fixed in a more stable state, and the inclination angle of the coil portion 4 and the backrest portion 5 is increased. It can be changed safely and more easily.

As a method of controlling the gas spring 61, for example, physical control using a lever or electrical control using a motor or the like can be used. Hereinafter, as shown in FIG. 12, a case where a physical control method using a lever is adopted will be described as an example. The lever 63 is rotatably fixed below the base portion 2. A link member 64 connected to the rotating portion 622b of the pusher 622 is connected to the lower portion of the lever 63. By moving the upper end of the lever 63 back and forth, the link member 64 moves back and forth in conjunction with each other. Due to the back-and-forth movement of the link member 64, the button pressing portion 622a rotates in conjunction with the rotational movement of the rotating portion 622b, and the push pin 61e is pressed or released. As a result, the push pin 61e is pressed to extend the piston rod 61b, or the coil portion 4 and the backrest portion 5 are pushed down to push the piston rod 61b into the main body tube 61a, so that the angles of the coil portion 4 and the backrest portion 5 are adjusted. For example, it can be adjusted from the horizontal direction (0 °) to the substantially vertical direction (90 °).
