Description

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

As a method for examining the inside of digestive organs such as the esophagus and the gastrointestinal tract, a capsule endoscope has been studied. Since the capsule endoscope does not need to pass a tube for operating the camera through the throat of the subject unlike the conventional endoscope, the burden on the subject can be greatly reduced. In a capsule endoscope that has been studied so far, a subject swallows a capsule with a built-in camera, and the capsule moves inside the body by movement of the digestive organ itself such as peristalsis, and images 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 position in the movement by peristalsis, it cannot cope with a case where detailed observation of a specific position is desired. Furthermore, in a digestive organ having a relatively large space such as the stomach, the capsule endoscope moves by peristalsis, and it is difficult to observe the entire interior in detail. Therefore, when examining the stomach and other digestive organs, there is a problem that the examination by the capsule endoscope and other examination methods must be used in combination, and the labor of the examination increases.

  In recent years, therefore, self-propelled capsule endoscopes have attracted attention. The self-propelled capsule endoscope is a capsule endoscope provided with moving means such as a fin. After the subject swallows the self-propelled capsule endoscope or inserts it from the anus, the capsule endoscope can be freely moved by controlling the moving means from outside the body. Patent Document 1 relates to an invention of a self-propelled capsule endoscope newly disclosed by the present inventor. Patent document 1 attaches a fin with a magnet to a capsule endoscope, and after the subject swallows or inserts the self-propelled capsule endoscope from the anus, radiates a magnetic field to the subject lying on the examination table. The technique which can control the self-propelled capsule endoscope in a test subject's body from the outside of the body is disclosed.

WO2015 / 181993

Since the self-propelled capsule endoscope can inspect a plurality of organs by a single inspection method, the patient's restraint time is relatively long compared to the case of inspecting only one organ. A subject who undergoes an examination using a self-propelled capsule endoscope must maintain the same posture on the examination table for a long time, and often feels 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 as much as possible by maintaining the same posture for a long time.

  In order to achieve the above object, the examination table according to claim 1 is rotatable to the base part so that the base part, the gantry part provided on the base part, and the inclination angle can be changed. A coil part having a hollow part connected to the coil part, a backrest part fixed to an edge part forming the hollow part of the coil part, and the coil part and the backrest part by rotating the coil part according to expansion and contraction And an angle adjustment mechanism provided on the base portion for adjusting the inclination angle of the base plate.

  The examination table according to claim 2 is characterized in that, in the examination table according to claim 1, the angle adjusting mechanism is connected to a coil portion.

  The examination table according to claim 3 is the examination table according to claim 1 or 2, wherein the angle adjusting mechanism is a gas spring.

  The examination table according to claim 4 is the examination table according to any one of claims 1 to 3, wherein a footrest part capable of adjusting an inclination angle is rotatably connected to a base part or a gantry part. It is characterized by that.

  According to the examination table according to the present invention, the physical burden on the subject in the examination using the self-propelled capsule endoscope can be reduced. Further, by changing the posture of the subject, for example, watching TV or reading can be easily performed, so that the mental burden on the subject can be reduced. Furthermore, according to the examination table according to the present invention, it is possible to perform not only other examinations performed while lying down on the body while performing examinations using a self-propelled capsule endoscope, but also other examinations performed by raising the body at the same time. it can. Therefore, when it is necessary to perform a plurality of inspections including an inspection using a self-propelled capsule endoscope, these inspections can be performed simultaneously, so that the inspection time can be greatly shortened.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  Fig.1 (a)-(c) is the whole medical examination table 1 concerning this embodiment. This examination table 1 has a base part 2, a base part 3 provided on the base part 2, and a coil part having a hollow part rotatably connected to the base part 2 so that the inclination angle can be changed. 4, a backrest portion 5 fixed to an edge portion forming a hollow portion of the coil portion, and a base portion that rotates the coil portion 4 according to expansion and contraction to adjust the inclination angle of the coil portion 4 and the backrest portion 5 2 and an angle adjusting mechanism 6 provided in the position 2. In addition, the examination table 1 can be provided with a footrest portion 7 that is rotatably connected to the base portion 2 or the gantry portion 3 so that the inclination angle can be adjusted as necessary. Hereinafter, each component will be described in detail.

1. Base 2
The base part 2 is a part that supports the gantry part 3, the coil part 4, and the like. As shown in FIGS. 2A and 2B, the base unit 2 includes a base body 2a that fixes the base 3 and rotatably connects the coil 4 and a base body 2a. Further, a base auxiliary part 2b having a small height and a small area is continuously provided. The base auxiliary part 2b has such a height that a lower part of the coil part 4 can be accommodated when a coil part 4 and a backrest part 5 described later are in a horizontal state. Although this base auxiliary | assistant part 2b is not necessarily required, there exist the following effects by connecting with the base main-body part 2a. As will be described later, the weight of the very heavy coil part 4 and the weight applied to the backrest part 5 when the subject lies down are applied to the base body 2a. In such a case, the presence of the base auxiliary portion 2b can prevent the examination table 1 from falling and improve the stability of the examination table 1. The size of the base main body 2a and the base auxiliary portion 2b can be appropriately changed depending on various conditions such as the location of the examination table 1, the size of the coil portion 4, and whether or not a footrest 7 described later is provided. is there.

  As shown in FIGS. 2A and 2B, the base unit 2 is assembled using many frames 21. 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 Glyce fiber. In order to reduce the weight of the examination table 1 as much as possible, it is more preferable to select aluminum. Each frame 21 is assembled by being connected by a conventional fixing means such as screws.

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

  The base part 2 may have support leg parts 23 on the lower surface thereof as necessary. Moreover, the circumference | surroundings of the base part 2 can be covered with a panel etc. (not shown).

2. Mounting unit 3
The gantry 3 is a pedestal for supporting the lower body of the subject. The gantry 3 is, for example, a flat plate and is provided on the upper surface of the pedestal 2 so as to be substantially horizontal. The gantry 3 is, for example, a plate that has a rectangular shape with a longitudinal direction of about 100 cm and is provided with screw holes. The gantry 3 is screwed to the upper surface of the base body 2a of the base 2 through the screw hole.

3. Coil part 4
The coil unit 4 is a magnetic field generation unit that radiates to the subject a magnetic field for controlling the self-propelled capsule endoscope taken into the subject's body from outside the body. The coil part 4 has a hollow part. As will be described later, the hollow portion is a space in which the upper body of the subject is stored. The coil part 4 is rotatably connected to the base part 2 so that the inclination angle can be changed. The shape of the coil part 4 is not particularly limited as long as it has a hollow part. The shape of the coil portion 4 may be, for example, a triangle, a quadrangle (for example, see FIG. 3A), a polygonal cylinder such as a pentagon and a hexagon, or a cylinder or an elliptical cylinder. Good. Moreover, it is not restricted to a cylindrical shape, The shape which connected the coil and the coil with the rod-shaped support member may be sufficient. Hereinafter, the coil part 4 will be described in detail by taking the rectangular cylindrical coil part 4 as an example (see FIG. 3A).
The coil unit 4 can include a coil for generating a 1-3 axis magnetic field. Below, the structure and assembly method of the coil part 4 are demonstrated by making into an example the coil part 4 which has a coil which generates a triaxial magnetic field.

  As shown in FIG. 3B, the coil unit 4 includes coils that surround the inside from three directions orthogonal to each other, that is, x-axis coils 4x, 4x ′ that generate magnetism in the x-axis direction, and the y-axis. Y-axis coils 4y and 4y ′ that generate magnetism in the direction, and z-axis coils 4z and 4z ′ that generate magnetism in the z-axis direction. The coil unit 4 is configured such that these coils can surround the subject, and the subject swallows the self-propelled capsule endoscope from the mouth or inserts from the anus, and is positioned in three directions orthogonal to each other, that is, on the six surfaces. The inside of the body is inspected by controlling the progress of the self-propelled capsule endoscope in the body by the magnetic field from the coil.

Since each coil is a coil for generating a magnetic field, an iron core used in an electromagnet is not used. Each coil is manufactured by winding a plurality of conductive wires in a circumferential shape and solidifying them with tape or resin.
More preferably, each coil is installed in a coaxial and parallel manner so that a circumferential coil having a plurality of conductive wires wound is separated by the same distance R ′ as the radius R so as to generate a uniform magnetic field in the central axis. preferable. However, as described above, each coil is manufactured by wrapping multiple metal conductors, so each coil is very heavy. Therefore, if each coil is made as small as possible, the weight of the coil portion 4 can be reduced, and the size of the examination table 1 can be further reduced. On the other hand, as will be described later, the subject is passed through the hollow part of the coil part 4, and the self-propelled capsule endoscope is controlled by the magnetic field generated by the coil part 4. It is preferable that the size of the hollow portion of the coil portion 4 is a size that allows a human body to pass through. Therefore, for example, the x-axis coils 4x and 4x ′ are sized to pass the human body, and the sizes of the y-axis coils 4y and 4y ′ and the z-axis coils 4z and 4z ′ are determined by the x-axis coils 4x and 4x ′. It is preferable that the size be separated by a distance half the radius R of the x-axis coil (1 / 2R).

The coil unit 4 is manufactured by combining the x-axis coils 4x and 4x ′, the y-axis coils 4y and 4y ′, and the z-axis coils 4z and 4z ′. Each coil is combined as follows, for example.
First, as shown in FIG. 4A, the base beam member 41x and the connection beam member 42x are combined and fixed with screws or the like to form a base for placing the x-axis coil 4x. Next, the frame members 43za and 43zb are fixed to the base beam member 41x, and the frame member 43ya is fixed to the connection beam member 42x with screws or the like. The frame member 43ya has a screw through hole 44 connected to the coil connecting portion 22 of the base portion 2 using a bolt or the like. Next, as shown in FIG. 4B, the x-axis coil 4x is placed on the base that has been 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 connection beam member 42x with screws or the like. The frame member 43y′a has a screw through hole 44 connected to the coil connecting portion 22 of the base portion 2 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 coils 4y, 4y' and the z-axis coils 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 connection beam member 42x' using screws or the like, respectively. 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' 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 holding blocks 45y, 45y ′, 45z and 45z ′ are fixed to the inside of each frame member 43, and the y-axis coils 4y and 4y ′ and the z-axis coils 4z and 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 the pressing blocks 45 using screws or the like. As will be described later, the backrest portion 5 is fixed to an edge portion forming a hollow portion of the coil portion 4. For example, a screw hole for fixing the backrest 5 to the inner plate 46z can be provided.

  The assembled coil part 4 is screwed and connected to the screw through hole 44 and the screw through hole 22b of the coil connecting part 22 provided in the base part 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 connection member 47 for connecting to one end of the angle adjusting mechanism 6 is attached to the frame member 43y'a. (See FIG. 7A). Moreover, you may cover the circumference | surroundings of the coil part 4 with the cover 48 (refer FIG.7 (b)).

4). Backrest part 5
The backrest 5 has a frame 51 as shown in FIG. 8 (a) whose frame is assembled into a rectangular shape, and a plate 52 as shown in FIG. It is assembled by fixing with the fixing means. In this case, it is in a horizontal state located in substantially the same plane as the gantry 3 described above, and in this state, the upper surfaces of both are substantially flush. Moreover, since the backrest part 5 changes the inclination angle together with the coil part 4, an appropriate gap is provided between the backrest part 5 and the gantry part 3. The backrest portion 5 can have a longitudinal direction of about 100 cm, for example. The backrest part 5 is fixed to an edge part forming a hollow part of the coil part 4, specifically, to an inner plate 46 z of the coil part 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 by using a fixing means such as a screw (see FIG. 9A), and then the plate 52 is attached to the frame portion 51. You may affix (refer FIG.9 (b)).

5. Angle adjustment mechanism 6
As described above, the angle adjustment mechanism 6 is a mechanism that is provided in the base portion 2 and adjusts the inclination angles 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 a 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, the angle adjusting mechanism 6 can be made as small and light as possible, and the angles of the coil portion 4 and the backrest portion 5 can be changed more freely. Hereinafter, in each drawing, the angle adjustment mechanism 6 is represented by a gas spring. Hereinafter, the angle adjustment 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 parts 61c and 61d provided in the main body tube 61a and the piston rod 61b, respectively. . A push pin 61e is provided on the inner side of the tip 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. The gas spring 61 is shortened by pushing the piston rod 61b into the main body tube 61a.

  The gas spring 61 is fixed to the base part 2 as described above. When the gas spring 61 is fixed to the base portion 2, an attachment fixing portion 62 as shown in FIGS. 10 (b) to 10 (d) is used. The attachment fixing portion 62 includes a substantially trapezoidal attachment main body portion 621 and a pusher 622 that is rotatably attached to the attachment main body portion 621 and can press or release the push pin 61e by rotating. As shown in FIG. 2C, the attachment main body 621 includes two substantially trapezoidal plates 621a and a spacer 621b for providing a gap between the plates 621a. A piston rod side tip 61d of the gas spring is inserted into a gap between the plates 621a provided by the spacer 621b, and is fixed to the plate 621a so as to be rotatable by screw fastening using bolts, nuts, or the like. In addition, a button pressing portion 622a of a pusher 622 is provided in the gap. The button pressing portion 622a is connected to a rotating portion 622b provided outside the plate 621a, and the button pressing portion 622a also rotates when the rotating portion 622b rotates. The form which assembled the gas spring 61 and the attachment fixing | fixed part 62 is shown by FIG.

The distal end 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 attachment fixing portion 62 is fixed to the base portion 2 with screws or the like. As described above, the inclination angle of the coil part 4 and the backrest part 5 is adjusted by extending and contracting the gas spring 61.
In addition, as described above, the coil portion 4 is very heavy because it includes a coil manufactured by winding a conductive wire in multiple layers. By fixing the distal end portion 61c of the gas spring 61 to the connection member 47 of the coil portion 4, the inclination angle of the coil portion 4 and the backrest portion 5 can be further increased while fixing the very heavy coil portion 4 in a more stable state. It can be changed safely and more easily.

  As a method for 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, a case where a physical control method using a lever is employed as shown in FIG. 12 will be described as an example. The lever 63 is fixed to the lower part of the base part 2 so as to be rotatable. A link member 64 connected to the rotating portion 622 b 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. By the back-and-forth movement of the link member 64, the button pressing part 622a is rotated in conjunction with the rotational movement of the rotating part 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, whereby the angles of the coil portion 4 and the backrest portion 5 are increased. For example, it can be adjusted between the horizontal direction (0 °) and the substantially vertical direction (90 °).

6). Footrest 7
The examination table 1 of the present invention can be provided with a footrest portion 7 as necessary. As shown in FIG. 13A, the footrest portion 7 is connected to the base portion 2 or the gantry portion 3 so that the inclination angle can be changed. The footrest 7 includes a footrest main body 71 on which the subject's feet are placed and a mechanism 72 for adjusting the angle of the footrest main body 71. As the mechanism 72, a general mechanism conventionally used in a chair or a 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. In FIG. 13, a gas spring is illustrated as an example of the mechanism 72. The angle of the footrest 7 can be changed by operating using the lever 73 in the same manner as the gas spring as the angle adjusting mechanism 6. Further, by raising the coil part 4 and the backrest part 5 and tilting the footrest part 7, the examination table 1 can be formed into a chair shape as shown in FIG. 13 (b). By setting it as a chair shape, the installation area of the examination table 1 of the present invention can be reduced, and the examination table 1 of the present invention can be installed not only in large hospitals but also in small hospitals.

7). Usage Mode of Examination Table of the Present Invention A subject P who swallows or inserts a self-propelled capsule endoscope from the anus lies on the examination table 1 (see FIG. 14A).
