Description

[Technical field]

[0001] The present invention relates to an apparatus for training the operation of medical equipment such as an endoscopic surgery apparatus. [Background technology]

[0002] Conventionally, when performing endoscopic examinations and endoscopic surgery, doctors need to become proficient in operating various medical devices, including the operation of the endoscope. In recent years, surgical support robots that use robotic arms (robotic forceps) to perform laparoscopic surgery have become widespread, and doctors must be fully trained in the operation techniques of these surgical support robots.

[0003] For example, a training device for practicing the operation of an endoscope has been proposed, in which a simulated torso is fixed to a fixed base so as to be freely rotatable about a horizontal axis (see Patent Document 1). Simulated organs are also placed inside the simulated torso. By changing the fixed angle of the simulated torso, lateral and supine positions can be reproduced while an endoscope is inserted into the simulated organs inside the simulated torso, allowing the user to practice the operation of the endoscope.

[0004] Also, for example, a device has been proposed that holds both ends of a tubular organ excised from a living animal other than a human in a sealed state on a fixed table (see Patent Document 2). With this training device, air is introduced into the tubular organ to inflate it, and an endoscope is inserted into the organ to practice manipulating it, allowing a feeling close to the actual clinical condition to be obtained.

[0005] [Patent Document 1] JP2004-49479A [Patent Document 2] JP2006-81568A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the training device in Patent Document 1 has the problem that a large space must be prepared for training because the device is large overall. In addition, because the torso itself is modeled using resin or the like, it is difficult to practice endoscopic surgery such as tumor resection.

[0007] Furthermore, the training device of Patent Document 2 requires the preparation of a clean tubular organ without holes, which makes it difficult to practice.

[0008] Furthermore, these conventional training devices have the problem that it is difficult for a third party other than the person undergoing the training to recognize the operating state of the endoscope from the outside.

[0009] In view of the above circumstances, the present invention provides a medical device operation training device which requires only simple preparation work and enables the training of various procedures. [Means for solving the problem]

[0010] The present invention, which achieves the above-mentioned object, is a medical equipment operation training device used when practicing the operation of medical equipment, characterized in that it comprises a simulated organ holding section for diseased area that holds a sheet-shaped simulated organ for diseased area, at least a portion of which can be incised or excised, and a simulated organ for path holding section for path holding the simulated organ for path guiding the medical equipment to the simulated organ for diseased area.

[0020] In relation to the medical equipment operation training device, the pathway simulated organ may be characterized in that it has a cylindrical pathway member on the upstream side of the pathway member.

[0021] The medical equipment training device may be characterized in that a maximum width of the cylindrical pathway member is larger than a width of an inner wall of the pathway member.

[0022] The medical equipment operation training device may further include a mechanism for relative movement around a horizontal axis for changing the relative angle around a horizontal axis extending horizontally between the pathway simulated organ and the diseased part simulated organ.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0028] <Overall composition>

[0029] 1 to 3 show the overall configuration of a medical equipment operation training device (hereinafter referred to as training device) 1. Note that this training device 1 is intended for training in the operation of an endoscope during an endoscopic examination or endoscopic surgery, but the present invention is not limited to this.

[0030] The training device 1 has a base 10, a simulated organ holding section 20 for the first pathway, a simulated organ holding section 25 for the second pathway, a simulated organ holding section 40 for the diseased area, a base planar relative movement mechanism 60, a base vertical relative movement mechanism 70, a base vertical axis relative movement mechanism 80, and a horizontal axis relative movement mechanism 90.

[0031] The base 10 has a plate structure having legs 12 at the four corners. In this embodiment, the surface (upper surface) of the base 10 is a horizontal plane, but the surface may be inclined relative to the horizontal.

[0032] For ease of explanation, the desired direction parallel to the surface of the base 10 is defined as the X-axis, the direction parallel to the surface of the base 10 and perpendicular to the X-axis is defined as the Y-axis, and the direction perpendicular to the surface of the base 10 (XY plane) is defined as the Z-axis. The X-axis may be referred to as the front-rear axis, the Y-axis as the horizontal axis, and the Z-axis as the base vertical axis. In the Y-axis (horizontal axis), the side of the first path simulated organ holding unit 20 may be referred to as the Y-axis surgeon side, and the side of the diseased part simulated organ holding unit 40 may be referred to as the Y-axis diseased part side. In the X-axis (front-rear axis), the side approaching the surgeon may be referred to as the X-axis front side, and the direction away from the surgeon may be referred to as the X-axis rear side.

[0033] <Mock organ holder for the first pathway>

[0034] The first pathway simulated organ holding section 20 is placed on the base 10 and holds the first pathway simulated organ 100. The first pathway simulated organ 100 is composed of a cylindrical member (cylindrical pathway member) made of a bendable resin, and in this embodiment, functions as a simulated organ simulating an oral cavity and an esophagus. Here, a cylindrical member with a circular cross section is illustrated, but the present invention is not limited to this, and any structure capable of guiding a medical instrument along a desired pathway, such as a cylindrical shape with a polygonal cross section, a half cylinder (partial cylinder) shape, or a groove shape, may be used. The width of the first pathway simulated organ holding section 20 is preferably less than 40 mm, and more preferably 30 mm or less. In comparison with the maximum width of the second pathway simulated organ holding section 25 described later, which is 40 mm or more, the first pathway simulated organ holding section 20 can be defined as a narrow-width pathway member.

[0035] The first pathway simulated organ holding section 20 has holders 22A-22E that hold the first pathway simulated organ 100 at multiple points in the longitudinal direction, and a base 23 on which the holders 22A-22E are placed. The path direction of the pathway simulated organ 100 can be freely changed by arranging the holders 22A-22E. In this embodiment, the upstream region of the pathway simulated organ 100 is held by the holder 22A to imitate the oral cavity of a living organism extending in the X-axis direction. The downstream side of the upstream region is a curved path that is curved in the Y-axis direction by the holder 22B, and the midstream region located downstream of this curved path is held by the holders 22C and 22D to extend in the Y-axis direction, imitating the so-called esophagus. Furthermore, the downstream region of the midstream region is held by the holder 22E to be inclined downward in the Z-axis toward the Y-axis affected area, imitating the inclined exit from the esophagus to the stomach.

[0036] (Angle adjustment mechanism)

[0037] The base 23 of the simulated organ holder 20 for the first pathway is provided with an angle adjustment mechanism 24 having a hinge structure capable of adjusting the inclination angle of the holder 22E, specifically the inclination angle m that displaces downward along the Z axis as it advances toward the diseased part along the Y axis. Since there are individual differences in this inclination angle depending on the lateral position of the living body, practice is possible at various inclination angles. As shown in the setting sheet of Fig. 8, when the horizontal state is 0 degrees, the angle adjustment mechanism 24 can be set to 10 degrees, 20 degrees, 30 degrees, and 40 degrees in the Z axis downward direction (positive angle direction) and to -10 degrees and -20 degrees in the Z axis upward direction (negative angle direction).

[0038] <Mock organ holder for the second pathway>

[0039] The second pathway simulated organ holding section 25 is a member fixed to the lower end of the first pathway simulated organ 100 and holds the second pathway simulated organ 120. The second pathway simulated organ 120 is a plate-shaped or tubular pathway member made of resin, metal, or the like and having a desired rigidity, simulating a part of the stomach wall. The second pathway simulated organ 120 of this embodiment is a pathway member including a strip-shaped region 121 (see FIG. 2) in which both side edges in the strip width direction are raised in a strip shape extending in the pathway direction. Furthermore, the strip-shaped region 121 is a region in which the strip width gradually or stepwise increases from the upstream to the downstream, and therefore can be defined as a widening type pathway member. In this embodiment, the upper part of the strip-shaped region 121 of the second pathway simulated organ 120 is open, so that it can be defined as a so-called partially cylindrical or curved spatula-shaped open type pathway member, improving visibility from the outside. On the other hand, the second pathway simulated organ 120 is not limited to an open type, and may be a (wide-diameter type) cylindrical structure having a strip-shaped region 121 in a part thereof, such as a cylindrical shape, a trumpet shape, or a (circular) truncated cone shape, as shown in Fig. 18. Furthermore, the maximum width of the strip-shaped region 121 in the second pathway simulated organ holding section 25 is preferably, for example, 40 mm or more, more preferably 60 mm or more. This is because the second pathway simulated organ holding section 25 requires a suitable width to simulate the inner wall near the entrance of the stomach. As a result, the maximum width of the second pathway simulated organ holding section 25 is wider than that of the first pathway simulated organ 100 which simulates the esophagus, and therefore it can also be defined as a wide-width pathway member.

[0040] The second pathway simulated organ 120 is arranged so as to be continuous with the downstream side of the lower end (esophageal outlet) of the first pathway simulated organ 100 by the second pathway simulated organ holding section 25. The pathway direction (extension direction) of the lower end of the first pathway simulated organ 100 and the pathway direction (extension direction) of the second pathway simulated organ 120 form an angle n. Although not shown here, the second pathway simulated organ holding section 25 may be provided with an angle adjustment mechanism capable of adjusting this angle m. As shown in the setting sheet of FIG. 8, the second pathway simulated organ holding section and the second pathway simulated organ 120 can be selected to be used or not used.

[0041] <Mock organ holder for affected area>

[0042] The simulated organ holder 40 for diseased area holds a simulated organ 140 for diseased area, at least a part of which can be incised or excised. In this embodiment, the simulated organ 140 for diseased area is made of a flexible and / or stretchable sheet material. For example, the simulated organ 140 for diseased area can be a sheet of a simulated animal organ described in Japanese Patent Application No. 2016-538138. That is, the present specification incorporates all of the descriptions in Japanese Patent Application No. 2016-538138 (WO2017 / 010190). For example, the simulated animal organ can be manufactured by a molding process in which raw materials mainly composed of mannan are mixed with water, gelatinized, and molded to obtain a molded body, and a low-temperature process in which the molded body is maintained in a low-temperature environment lower than room temperature.

[0043] The diseased area simulated organ holding section 40 has a first holding section 42, a second holding section 44, a third holding section 46, and a fourth holding section 48. The first holding section 42, the second holding section 44, the third holding section 46, and the fourth holding section 48 hold the sheet-shaped diseased area simulated organ 140 in the circumferential direction (the peripheral direction of the sheet) in this order. The first holding section 42, the second holding section 44, the third holding section 46, and the fourth holding section 48 are clamping members having an elastic clip structure, and hold the diseased area simulated organ 140 by clamping the peripheral edge of the organ.

[0044] For ease of explanation, the straight line connecting the first retaining part 42 and the third retaining part 46 is defined as the first diagonal line T1, the straight line connecting the second retaining part 44 and the fourth retaining part 48 is defined as the second diagonal line T2, and the straight line that intersects with the midpoint M of the first diagonal line T1 and is parallel to the Y-axis is defined as the reference axis line C.

[0045] The diseased area simulated organ holding part 40 further has a first base 41 that supports the first holding part 42 and the third holding part 46, and a second base 43 that supports the second holding part 44 and the fourth holding part 48. A tension adjustment mechanism 56 is provided between the second base 43 and the fourth holding part 48.

[0046] The first base 41 is a U-shaped or C-shaped member extending parallel to the first diagonal line T1 while avoiding an area including the first diagonal line T1 connecting the first holding part 42 and the third holding part 46. In other words, the first base 41 supports the first holding part 42 and the third holding part 46 at both ends thereof while ensuring a simulated organ holding space between the first holding part 42 and the third holding part 46. The first base 41 is rotatable around the Y axis by a horizontal axis relative movement mechanism 90 described later.

[0047] The second base 43 is held by the first base 41. The second base 43 is a U-shaped or C-shaped member that avoids interference with a region including a second diagonal line T2 connecting the second holding portion 44 and the fourth holding portion 48. More specifically, the second base 43 has a seat portion 43A fixed to the first base 41 and extending in the Y-axis direction, a first arm 43B rotatably arranged on the Y-axis surgeon side of the seat portion 43A, and a second arm 43C rotatably arranged on the Y-axis affected part side of the seat portion 43A.

[0048] (Holding part displacement mechanism)

[0049] The first arm 43B is an L-shaped member, one end of which is held to be swingable relative to the first pivot shaft 51B of the seat 43A. The second holding part 44 is provided at the other end of the first arm 43B. The first pivot shaft 51B is parallel to the first diagonal line T1. As shown in FIG. 2, when viewed from the first diagonal line T1, the first pivot shaft 51B is offset to one side (upper side in FIG. 2) with the reference axis C as a boundary. Returning to FIG. 1, one side 43B1 of the L-shape of the first arm 43B has an angle with respect to the first diagonal line T1, and here extends in a direction that is approximately perpendicular to the first diagonal line T1. The other side 43B2 of the L-shape of the first arm 43B extends in a direction parallel to the first diagonal line T1, and the second holding part 44 is fixed to the distal end approaching the midpoint M of the first diagonal line T1. 6, when the first arm 43B is swung, the second holding part 44 located on the Y-axis surgeon side of the first diagonal line T1 can freely move back and forth in a direction including at least a circumferential component U of the first diagonal line T1 (i.e., a state in which the movement is not limited to the radial component of the first diagonal line T1). In other words, the seat part 43A, the first rotating shaft 51B and the first arm 43B constitute a second holding part displacement mechanism 50B that displaces the second holding part 44 in a direction including at least a circumferential component U of the first diagonal line T1.

[0050] The second arm 43C is an L-shaped member, one end of which is held to be swingable relative to the second pivot shaft 51C of the seat 43A. The other end of the second arm 43C is provided with a fourth holding part 48. The second pivot shaft 51C is parallel to the first diagonal line T1. As shown in an enlarged view in FIG. 5, the second pivot shaft 51C is offset to one side (the same side as the first pivot shaft 51B) with the reference axis C as a boundary when the first diagonal line T1 is viewed axially. One side 43C1 of the L-shape of the second arm 43C is angled with respect to the first diagonal line T1, and here extends in a direction that is approximately perpendicular to the first diagonal line T1. The other side 43C2 of the L-shape of the second arm 43C extends in a direction parallel to the first diagonal line T1, and the fourth holding part 48 is fixed to a distal end on the side of the midpoint M of the first diagonal line T1 via a tension adjustment mechanism 56. Therefore, as shown in Fig. 6, when the second arm 43C is swung, the fourth holding part 48 located on the Y-axis affected part side of the first diagonal line T1 can freely move back and forth in a direction including at least the circumferential component U of the first diagonal line T1. In other words, the seat part 43A, the second pivot shaft 51C, and the second arm 43C constitute a fourth holding part displacement mechanism 50C that displaces the fourth holding part 48 in a direction including the circumferential component U of the first diagonal line T1.

[0051] (Tension adjustment mechanism)

[0052] As shown in FIG. 5, the tension adjustment mechanism 56 is a linear mechanism that moves the fourth holding part 48 back and forth in a straight line along a direction parallel to one side 43C1 of the second arm 43C. As a result, the tension adjustment mechanism 56 plays a role in moving the fourth holding part 48 back and forth in a direction including a radial component R of the first diagonal line T1. A position approaching the first diagonal line T1 is defined as "proximal", and a position away from the first diagonal line T1 is defined as "distal". Here, the tension adjustment mechanism 56 is provided on the fourth holding part 48 side, but it may be provided on the second holding part 44 side, or it may be provided on both the second holding part 44 and the fourth holding part 48. The tension adjustment mechanism may be provided on the first holding part 42 and / or the third holding part 46 side, and in that case, it is sufficient to move the fourth holding part 48 back and forth in a direction including at least a radial component with respect to the second diagonal line T2 connecting the second holding part 44 and the fourth holding part 48.

[0053] Incidentally, the second retaining portion displacement mechanism 50B and the fourth retaining portion displacement mechanism 50C also allow the second retaining portion 44 and the fourth retaining portion 48 to freely move back and forth in a direction including the radial component R of the first diagonal line T1. Therefore, in this embodiment, the second retaining portion displacement mechanism 50B and the fourth retaining portion displacement mechanism 50C also serve as tension adjustment mechanisms.

[0054] (Description of holding part placement)

[0055] Next, the arrangement of the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48 in the diseased area simulated organ holding part 40 will be described. For ease of description, when the first diagonal line T1 connecting the first holding part 42 and the third holding part 46 is viewed axially from a specific direction, one side with the reference axis C as a boundary line may be referred to as "one side of the surgical surface" and the other side with the reference axis C as a boundary line may be referred to as "other side of the surgical surface".

[0056] As shown in FIG. 1, three points selected from the four holding positions of the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48 form the vertices of a triangle, and by using these three points to hold the simulated organ 140 for the diseased area, a surgical surface is formed on the simulated organ 140 for the diseased area.

[0057] The three positions may be selected in various ways. For example, the first surgical surface S1 is formed at the three holding positions of the first holding portion 42, the second holding portion 44, and the third holding portion 46. For example, the second surgical surface S2 is formed at the three holding positions of the second holding portion 44, the third holding portion 46, and the fourth holding portion 48. For example, the third surgical surface S3 is formed at the three holding positions of the first holding portion 42, the third holding portion 46, and the fourth holding portion 48. For example, the fourth surgical surface S4 is formed at the three holding positions of the first holding portion 42, the second holding portion 44, and the fourth holding portion 48.

[0058] That is, in this embodiment, four holding positions are prepared: the first holding portion 42, the second holding portion 44, the third holding portion 46, and the fourth holding portion 48, but the present invention is not limited to this, and a plane for surgery can be provided as long as there are at least three holding portions. Note that these first to fourth surgical surfaces S1 to S4 can also be curved or bent surfaces.

[0059] On the other hand, if the diseased area simulated organ 140 is held at at least four places, the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48, two surgical surfaces are simultaneously formed by the above three holding positions, and the area of ​​the surgical surface becomes wider. Although not shown in particular, if the holding parts are arranged in five or more places, the area of ​​the surgical surface can be further widened.

[0060] A first diagonal line T1 connecting the first holding portion 42 and the third holding portion 46 has an angle with respect to the Y axis, and is a right angle here. A second diagonal line T2 connecting the second holding portion 44 and the fourth holding portion 48 has an angle with respect to the first diagonal line T1, and is a right angle here.

[0061] As shown in an enlarged view in FIG. 6, when the first diagonal line T1 is viewed from a specific direction, the positioning location of the second holding portion 44 is the reference position P SET There are four positions: one-side first displacement position P1, which swings and displaces to one side at a first angle relative to the reference axis C; one-side second displacement position P2, which swings and displaces to one side at a second angle (greater than the first angle) relative to the reference axis C; and one-side third displacement position P3, which swings and displaces to one side at a third angle (greater than the second angle) relative to the reference axis C.

[0062] The positioning location of the fourth holding portion 48 is the reference position Q closest to the reference axis C. SET and one-side second displacement position Q2 that oscillates and displaces to one side at a second angle (greater than the first angle) with respect to the reference axis C. These positions are also reflected in the setting sheet in Figure 8.

[0063] (Explanation of preparation posture)

[0064] For example, when the second holding portion 44 is at the reference position P SET , the fourth holding portion 48 is at the reference position Q SET 10 to 13 show the training device 1 positioned in the above-mentioned state. The second diagonal line T2 is substantially parallel to the reference axis line C and intersects with or is closest to the first diagonal line T1. Since both the first and second rotating shafts 51B and 51C are offset from the first diagonal line T1 toward one side of the surgical surface, the second and fourth holding parts 44 and 48 approach the first diagonal line T1 by the rotation of the first and second arms 43B and 43C. As a result, when the diseased part simulated organ 140 is set, it is not necessary to apply excessive tension in the direction of the second diagonal line T2, and the second and fourth holding parts 44 and 48 are in a position (preparatory position) that makes it easy to clamp the diseased part simulated organ 140. For ease of explanation, the diseased area simulated organ 140 is omitted in FIGS. 12 and 13, and the second pathway simulated organ 120 is omitted in the cross section of FIG.

[0065] In this preparation position, when the diseased area simulated organ 140 is held by the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48, a desired tension is applied in the direction of the first diagonal line T1, and a tension smaller than the tension in the direction of the first diagonal line T1 (including zero tension in some cases) is applied in the direction of the second diagonal line T2. The first and third surgical planes S1 and S3 formed on the diseased area simulated organ 140 are both approximately parallel to the first diagonal line T1, the reference axis line C, and the second diagonal line T2, and together they form a single plane.

[0066] (Explanation of the first bending position)

[0067] When the first arm 43B is swung to position the second holding part 44 at the one-side second displacement position P2 and the second arm 43C is swung to position the fourth holding part 48 at the one-side second displacement position Q2, the first bending posture is shown by the solid lines in Figs. 1 to 9. As shown in Fig. 2, in this second bending posture, the second diagonal line T2 is substantially parallel to the reference axis C and is offset from the first diagonal line T1 by a second distance H2 toward one side of the surgical surface. In addition, compared to the preparation posture, the second holding part 44 and the fourth holding part 48 are moved away from the first diagonal line T1 by the rotation of the first arm 43B and the second arm 43C. As a result, the radial tension acting on the diseased part simulated organ 140 with respect to the first diagonal line T1 increases.

[0068] As shown in Fig. 1 and Fig. 4, the first surgical surface S1 and the third surgical surface S3 formed on the diseased part simulated organ 140 are inclined surfaces in which the amount of displacement from the reference axis C to one side of the surgical surface increases as the distance from the first diagonal line T1 increases in the direction of the reference axis C. That is, when viewed from the first diagonal line T1, the vicinity of the boundary line K1 between the second surgical surface S2 and the fourth surgical surface S4 is a curved surface that is convex toward the other side of the surgical surface. At the same time, as shown in Fig. 4, when viewed from the reference axis C (or Y-axis), the boundary line K2 between the first surgical surface S1 and the third surgical surface S3 is a curved surface that is concavely curved toward one side of the surgical surface. As a result, the center of the plane formed by combining the first surgical surface S1 and the third surgical surface S3 is a curved surface with a (single leaf) hyperboloid shape, a hyperbolic paraboloid shape, or a saddle shape. A desired tension acts on this curved surface in both the axial direction of the first diagonal line T1 and the radial direction of the first diagonal line T1 (from the midpoint M toward the second holding part 44 and the fourth holding part 48). This results in a shape and tension state that is very similar to that of the inner wall of an inflated stomach. For the sake of convenience, the second pathway simulated organ 120 is omitted in FIG. 4.

[0069] (Explanation of the second curved position)

[0070] As shown by the dotted line in FIG. 6, when the first arm 43B is swung to position the second holding part 44 at the first displacement position P1 on one side, and the second arm 43C is swung to position the fourth holding part 48 at the first displacement position Q1 on one side, the second bending posture is established. In this second bending posture, the second diagonal line T2 is in a twisted position that is substantially parallel to the reference axis C and offset from the first diagonal line T1 by a first distance H1 toward one side of the surgical surface. In addition, compared to the preparation posture, the second holding part 44 and the fourth holding part 48 are moved away from the first diagonal line T1 by the rotation of the first arm 43B and the second arm 43C. As a result, the radial tension acting on the diseased part simulated organ 140 with respect to the first diagonal line T1 increases.

[0071] This second bending posture is substantially the same as the first bending posture, but the second diagonal line T2 is offset from the first diagonal line T1 by a first distance H1, which is smaller than the second distance H2, toward one side of the surgical surface. As a result, the degree of opening (radius of curvature) of the (single leaf) hyperboloid, hyperbolic paraboloid, or saddle-shaped curved surface formed in the center of the plane formed by combining the first surgical surface S1 and the third surgical surface S3 becomes larger than that in the second bending posture.

[0072] (Explanation of the third curved position)

[0073] As shown by the dotted lines in Figure 6, when the first arm 43B is swung to position the second retaining portion 44 at the third displacement position P3 on one side, and the second arm 43C is swung to position the fourth retaining portion 48 at the second displacement position Q2 on one side, the third curved posture is achieved.

[0074] This third bending posture is similar to the first bending posture, but the second diagonal line T2 has an angle α with respect to the reference axis line C. Also, the second holding part 44 is closer to the first diagonal line T1 than in the first bending posture. As a result, the radial tension generated by the second holding part 44 is smaller than that in the first bending posture. As a result, the degree of opening (curvature radius) of the (single leaf) hyperboloid shape, hyperbolic paraboloid shape, or saddle shape curved surface formed in the center of the plane combining the first surgical surface S1 and the third surgical surface S3 changes with respect to the first and second bending postures.

[0075] (Explanation of the fourth curved position)

[0076] As shown by the dotted line in Fig. 6, when the first arm 43B is swung to position the second holding part 44 at the one-side second displacement position P2 and the second arm 43C is swung to position the fourth holding part 48 at the one-side first displacement position Q1, the fourth curved posture shown in Fig. 17 is obtained. In this way, the entire first surgical surface S1 and the third surgical surface S3 can be directed toward the surgeon in the Y-axis direction.

[0077] Although some holding positions are exemplified here, the holding position by the diseased area simulated organ holding section 40 can be varied in a variety of ways by combining one arbitrarily selected from the four holding positions in the second holding section 44 and one arbitrarily selected from the three holding positions in the fourth holding section 48.

[0078] For example, the second holding portion 44 is set to the one-side third displacement position P3, and the fourth holding portion 48 is set to the reference position Q SET In this case, the second diagonal line T2 is inclined with respect to the reference axis line C, so that the first surgical surface S1 and the third surgical surface S3 as a whole can be directed toward the surgeon in the Y-axis direction more than in the fourth bending posture. SET When the fourth holding portion 48 is moved to the second displacement position Q2 on one side, the second diagonal line T2 is inclined relative to the reference axis line C, so that the entire first surgical surface S1 and the third surgical surface S3 can be directed toward the patient in the Y-axis direction.

[0079] (Variations / Explanation of loose posture)

[0080] As shown in the modified example of FIG. 7, the second holding portion 44 is displaced to the other side with respect to the reference axis C at a second displacement position P OFF Similarly, the fourth holding portion 48 may be provided with an other-side displacement position Q OFFmay be provided. In this way, the second diagonal line T2 is approximately parallel to the reference axis line C and is in a twisted position offset from the first diagonal line T1 toward the other side of the surgical surface. In addition, the rotation of the first arm 43B and the second arm 43C causes the second holding part 44 and the fourth holding part 48 to approach the first diagonal line T1. In this posture, when the diseased part simulation organ 140 is held by the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48, a desired tension is applied in the direction of the first diagonal line T1, and an extremely small tension is applied in the radial direction of the first diagonal line T1 (including a state of zero tension). When viewed axially from the first diagonal line T1, the first surgical surface S1 and the third surgical surface S3 are concave inclined surfaces in which the amount of displacement from the reference axis line C toward the other side of the surgical surface increases as the distance from the first diagonal line T1 in the direction of the reference axis line C increases. If one wishes to practice operating on a surface with very loose tension, one may set the holding position in this way.

[0081] <Base plane relative movement mechanism>

[0082] As shown in FIG. 1, the base plane direction relative movement mechanism 60 changes the relative positions on the XY plane of the first path simulated organ 100 and the diseased part simulated organ holding part 40. Specifically, the base plane direction relative movement mechanism 60 is an XY displacement table, and has an X-axis linear motion part 62 arranged on the base 10 to realize the relative movement of the first path simulated organ holding part 20 in the X-axis direction, and a Y-axis linear motion part 64 arranged on the X-axis linear motion part 62 to realize the relative movement of the first path simulated organ holding part 20 in the Y-axis direction. As shown in the setting sheet in FIG. 8, the X-axis linear motion part 62 is set at 10 mm and 20 mm on the X-axis back side when the reference point is 0, and is set at -10 mm, -20 mm, -30 mm, -40 mm, and -50 mm on the X-axis front side. The Y-axis linear motion part 64 is set at 10 mm intervals between 10 mm and 200 mm on the Y-axis diseased part side when the reference point is 0.

[0083] <Base vertical relative movement mechanism>

[0084] As shown in Fig. 1, the base vertical relative movement mechanism 70 changes the relative positions in the Z-axis direction between the first path simulated organ 100 and the diseased area simulated organ holder 40. Specifically, the base vertical relative movement mechanism 70 is provided with a Z-axis linear motion part that is disposed on the base planar direction relative movement mechanism 60 and realizes the relative movement in the Z-axis direction of the first path simulated organ holder 20. As shown in the setting sheet in Fig. 8, the base vertical relative movement mechanism 70 is set up to 80 mm above the Z-axis at 10 mm intervals when the reference point is set to 0.

[0085] <Base vertical relative movement mechanism>

[0086] 1, the mechanism 80 for relative movement around the vertical axis of the base changes the relative angle around the Z axis between the simulated organ 100 for the first path and the simulated organ holder for diseased area 40. Specifically, the mechanism 80 for relative movement around the vertical axis of the base has position adjustment pins 82 arranged at equal intervals in the circumferential direction on a circular track centered on a vertical rotation axis E parallel to the Z axis on the base 10, a holding ring 88 arranged rotatably about the vertical rotation axis E on the base 10 and holding the simulated organ holder for diseased area 40, and a pair of position adjustment holes 84A, 84B provided at the lower end of the holding ring 88 and receiving the pair of position adjustment pins 82 located on a specific diameter of the circular track.

[0087] Here, a total of 12 position adjustment pins 82 are arranged at positions V1 to V12 spaced at 30 degree intervals in the circumferential direction around the vertical rotation axis E. As a result, by engaging one position adjustment hole 84A with a specific position adjustment pin 82 (V6 in FIG. 1) selected from V1 to V12 and engaging the other position adjustment hole 84B with the opposite position adjustment pin 82 (V12 in FIG. 1) located on the same diameter as the specific position adjustment pin 82, the fixing angle of the retaining ring 88 around the vertical rotation axis E with respect to the base 10 can be changed in 12 different ways. This is also reflected in the setting sheet shown in FIG. 8.

[0088] <Relative movement mechanism around horizontal axis>

[0089] The mechanism 90 for relative movement around the horizontal axis changes the relative angle between the first path simulated organ 100 and the diseased part simulated organ holder 40 around a rotation axis (horizontal rotation axis / horizontal axis) along the XY plane.

[0090] Specifically, the horizontal axis relative movement mechanism 90 has a holding ring 88 for holding the diseased area simulated organ holding part 40, and a pair of engagement parts 92A, 92B provided on both ends of the first base 41 of the diseased area simulated organ holding part 40 and engaging with the holding ring 88. The holding ring 88 is ring-shaped and is erected on the base 10 so that the central axis (horizontal rotation axis / horizontal axis) O of the ring is parallel to the XY plane. The diseased area simulated organ holding part 40 is disposed inside the holding ring 88. The pair of engagement parts 92A, 92B provided on the first base 41 engage with the holding ring 88 in the axial and radial directions and are slidable in the circumferential direction. When the pair of engagement parts 92A, 92B slide along the holding ring 88, the first base 41 rotates around the central axis O of the holding ring 88. In this embodiment, a first diagonal line T1 connecting the first holding portion 42 and the third holding portion 46 provided on the first base 41 approximately coincides with the diameter of the holding ring 88. In addition, a midpoint M of the first diagonal line T1 intersects with a central axis O of the holding ring 88.

[0091] The retaining ring 88 is provided with position adjustment holes 89 at positions W1 to W12 spaced at 30 degree intervals in the circumferential direction. One of the engagement parts 92A is provided with a position adjustment pin 93 that can engage with the position adjustment hole 89. As a result, by engaging the position adjustment pin 93 with a specific position adjustment hole 89 (W12 in FIG. 1) selected from W1 to W12, the fixing angle of the diseased area simulated organ 140 around the central axis O of the retaining ring 88 can be changed to 12 different angles. This is also reflected in the setting sheet shown in FIG. 8.

[0092] <Explanation of the correlation between training equipment and human organs>

[0093] FIG. 19 shows the correlation between the training device 1 and the organs of the human body. The first pathway simulated organ 100 simulates the oral cavity and esophagus 950 of the human body 900. The second pathway simulated organ 120 and the diseased part simulate part of the inner wall of the stomach 960 of the human body 900. Furthermore, the second pathway simulated organ 120 and the diseased part simulated organ 140 can freely change their relative positions. As a result, the diseased part simulated organ 140 can simulate diseased parts at various locations on the inner wall of the stomach 960.

[0094] <First practice method for medical equipment>

[0095] Fig. 9 shows a state in which the training device 1 is used to practice operating the endoscope 500. The training device 1 in Fig. 9 is set as follows: Y-axis linear motion unit 64: 50 mm, X-axis linear motion unit 62: 0 mm, base vertical relative movement mechanism 70: 30 mm, base vertical axis around relative movement mechanism 80: V6, horizontal axis around relative movement mechanism 90: W12, angle adjustment mechanism 24: 20 degrees, second holding unit 44: P2, fourth holding unit 48: Q2, tension adjustment mechanism 56: distal, second path simulated organ holding unit 25: used. As a result, the surgical surface of the diseased area simulated organ 140 faces the X-axis near side.

[0096] The operator who is practicing inserts the tip of the endoscope 500 from the upstream end of the first pathway simulated organ 100. When the operator pushes the endoscope 500 in, its tip pops out from the downstream end of the first pathway simulated organ 100 and is guided further downstream of the pathway while contacting the second pathway simulated organ 120. In this state, the operator accesses the diseased part simulated organ 140 by bending the tip region of the endoscope 500 toward the Y-axis rear side. At this time, the operator is required to operate the endoscope 500 in such a way that the reaction force that the endoscope 500 receives by contacting the front side wall of the second pathway simulated organ 120 is effectively utilized. After that, various treatment tools such as forceps, injection needles, and electronic scalpels are protruded from the tip of the endoscope 500 through the inside of the endoscope 500 to cut or excise the diseased part simulated organ 140.

[0097] <The second practice method for medical equipment>

[0098] Fig. 10 shows a state in which the training device 1 is used to practice operating an endoscope 500. Here, the work of placing a simulated organ 140 for diseased area in the simulated organ holding portion 40 for diseased area is shown. The training device 1 in Fig. 10 has a Y-axis linear motion portion 64: 50 mm, an X-axis linear motion portion 62: 0 mm, a base vertical relative movement mechanism 70: 30 mm, a base vertical axis around relative movement mechanism 80: V6, a horizontal axis around relative movement mechanism 90: W12, an angle adjustment mechanism 24: 20 degrees, a second holding portion 44: P SET , fourth holding part 48:Q SET , the tension adjustment mechanism 56: proximal, and the second pathway simulated organ holding portion 25: in use. As a result, the second holding portion 44 and the fourth holding portion 48 are closest to the first diagonal line T1.

[0099] The trainee clamps the diseased area simulant organ 140 using the first holding part 42, the second holding part 44, the third holding part 46, and the fourth holding part 48. After that, the trainee can move to the desired posture by rotating the first arm 43B and the second arm 43C to increase the tension.

[0100] <The third practice method for medical equipment>

[0101] 14 and 15 show a state in which the training device 1 is used to practice operating the endoscope 500. The training device 1 in Figs. 14 and 15 is set as follows: Y-axis linear motion unit 64: 50 mm, X-axis linear motion unit 62: 0 mm, base vertical relative movement mechanism 70: 30 mm, base vertical axis relative movement mechanism 80: V6, horizontal axis relative movement mechanism 90: W9, angle adjustment mechanism 24: 20 degrees, second holding unit 44: P2, fourth holding unit 48: Q1, tension adjustment mechanism 56: distal, second path simulated organ holding unit 25: used. As a result, the surgical surface of the diseased area simulated organ 140 faces downward along the Z axis.

[0102] The operator who is practicing inserts the tip of the endoscope 500 from the upstream end of the first pathway simulated organ 100. When the operator pushes the endoscope 500 in, its tip pops out from the downstream end of the first pathway simulated organ 100 and is guided further downstream of the pathway while contacting the second pathway simulated organ 120. In this state, the operator accesses the diseased part simulated organ 140 by bending the tip region of the endoscope 500 upward along the Z axis. At this time, the operator is required to operate the endoscope 500 in such a way that the reaction force that the endoscope 500 receives by contacting the bottom surface of the second pathway simulated organ 120 is effectively utilized. After that, various treatment tools such as forceps, injection needles, and electronic scalpels are protruded from the tip of the endoscope 500 through the inside of the endoscope 500 to cut or excise the diseased part simulated organ 140.

[0103] <The fourth practice method for medical equipment>

[0104] Fig. 16 shows a state in which the training device 1 is used to practice operating the endoscope 500. The training device 1 in Fig. 16 is set as follows: Y-axis linear motion unit 64: 50 mm, X-axis linear motion unit 62: 0 mm, base vertical relative movement mechanism 70: 30 mm, base vertical axis around relative movement mechanism 80: V2, horizontal axis around relative movement mechanism 90: W12, angle adjustment mechanism 24: 20 degrees, second holding unit 44: P2, fourth holding unit 48: Q1, tension adjustment mechanism 56: distal, second path simulated organ holding unit 25: used. As a result, the surgical surface of the diseased area simulated organ 140 faces the Y-axis back side.

[0105] The operator who is practicing inserts the tip of the endoscope 500 from the upstream end of the first pathway simulated organ 100. When the operator pushes the endoscope 500 in, its tip pops out from the downstream end of the first pathway simulated organ 100 and is guided further downstream of the pathway while contacting the second pathway simulated organ 120. In this state, the operator accesses the diseased part simulated organ 140 by bending the tip region of the endoscope 500 forward along the Y axis. At this time, the operator is required to operate the endoscope 500 in such a way that the reaction force that the endoscope 500 receives by contacting the inner side wall of the second pathway simulated organ 120 is effectively utilized. After that, various treatment tools such as forceps, injection needles, and electronic scalpels are protruded from the tip of the endoscope 500 through the inside of the endoscope 500 to cut or excise the diseased part simulated organ 140.

[0106] As described above, according to the training device 1 of this embodiment, the simulated organ for diseased area holding section 40 can hold the sheet-like simulated organ for diseased area 140, at least a part of which can be incised or excised. At the same time, the first and second pathway simulated organ holding sections 20 and 25 can hold the first and second pathway simulated organs 100 and 120 that guide the medical device (endoscope 500) to the simulated organ for diseased area 140. By separating the simulated organ for diseased area 140 from the first and second pathway simulated organ holding sections 20 and 25 in this way, it is possible to easily replace only the simulated organ for diseased area 140 after the procedure training.

[0107] Moreover, the simulated organ for the affected area 140 is a component for practicing incision and resection techniques, and is required to resemble an actual living body, so the manufacturing costs tend to be relatively high. As a result, it is required to have a minimum area and volume. On the other hand, the simulated organ holding parts for the first and second pathways 20, 25 do not need to be so similar to an actual living body to allow sufficient operation training. As a result, by manufacturing them from a material different from that of the simulated organ for the affected area 140, repeated use can be realized.

[0108] Furthermore, by forming the diseased area simulated organ 140 in a sheet shape, the operation status of the medical equipment can be visually confirmed from the outside. In other words, an instructor other than the practicing surgeon can visually confirm the operation status of the medical equipment from the outside and provide appropriate advice to the surgeon.

[0109] On the other hand, by forming the first pathway simulated organ 100 in a tubular structure, the procedure of inserting a medical device through a tubular organ such as the esophagus or blood vessels can be made closer to reality.

[0110] Furthermore, in this embodiment, the second pathway simulated organ 100 is independently arranged downstream of the first pathway simulated organ 100, so that the second pathway simulated organ 100 can simulate a part of the same organ as the diseased part simulated organ 140. Incidentally, in this embodiment, the second pathway simulated organ 100 and the diseased part simulated organ 140 each simulate the inner wall of the stomach. By simply changing the relative positions of the two, the diseased part simulated organ 140 can simulate diseased parts in various places in the stomach, which increases the variety of practice. Furthermore, the upper part of the second pathway simulated organ 100 is an open structure, which improves the visibility from the outside regarding the operation status of the medical equipment.

[0111] In this training device 1, the simulated organ holding section 40 for the affected area has a tension adjustment mechanism 56 that changes the tension acting on the simulated organ 140 for the affected area, so that it is possible to simulate a tense state, for example, when the inside of the stomach is inflated with air, while keeping the device in a sheet shape.

[0112] Furthermore, in this training device 1, the simulated organ holder 40 holds the simulated organ 140 so that a curved surface having a hyperboloidal, hyperbolic paraboloidal or saddle shape is formed on the surface of the simulated organ 140. This allows a taut curved surface to be formed while maintaining the sheet shape, so that it is possible to imitate, for example, a taut state caused by inflating the inside of the stomach with air.

[0113] As shown in Fig. 8, the training device 1 is equipped with a setting sheet that shows the settings of various movable parts in a diagram. This makes it possible to define various training postures by the settings on the setting sheet, and to easily reproduce the training postures. As a result, it is also possible to manage the progress of the training of the technique.

[0114] Incidentally, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
