Description

[Technical field]

[0001] The present disclosure relates to a front drape that covers a front portion of an arm unit included in a medical device, and also to a drape set including the front drape. [Background technology]

[0002] Surgical operations using surgical robots are becoming more widespread. In surgical operations using surgical robots, surgical instruments are connected to the tip of an arm unit provided on the surgical robot to perform a desired procedure. Examples of the surgical instruments that can be connected include forceps and an electric scalpel. In addition, an endoscope holding device equipped with an arm unit is also used during laparoscopic surgery. The endoscope holding device is used with an endoscope connected to the tip of the arm unit.

[0003] An arm unit provided in a medical device such as an endoscope holding device includes multiple arm parts and multiple joints. The arm unit operates according to a user's operation to move a connected medical device such as an endoscope to a desired position and hold the medical device in a desired posture.

[0004] Medical devices such as endoscope holding devices are difficult to sterilize because they contain electrical components, etc. For this reason, parts that may come into contact with patients or medical staff, such as the arm unit, are covered with clean drapes.

[0005] Covering a specific portion of a medical device with a clean drape in this manner is generally called draping. Hereinafter, an area in an operating room where a specific level of cleanliness is ensured will also be referred to as a clean field. An area where a specific level of cleanliness is not ensured and which is less clean than the clean field will also be referred to as an unclean field.

[0006] By covering the arm unit with a drape, the arm unit, which is an unclean field, can be separated from the clean field. That is, medical personnel working in the operating room are prevented from directly touching the arm unit, which is an unclean field. Alternatively, instruments that have been sterilized or otherwise made clean are prevented from directly touching the arm unit, which is an unclean field.

[0007] Patent Document 1 discloses a drape unit that covers a surgical robot. In this drape unit, a bearing structure is provided between a drape that covers the tip end of the arm of the surgical robot and a drape that covers the base end of the arm. The drape unit prevents the drape from being twisted and damaged when, for example, the tip end of the arm of the surgical robot rotates relative to the base end of the arm.

[0008] Patent Document 2 discloses a surgical drape for a robotic device. The surgical drape includes a first drape portion having an opening of a predetermined size and a predetermined shape, and a second drape portion overlapping the opening and covering at least a part of the opening. The first drape portion includes a fixing element for maintaining the position of the opening aligned with the position of a predetermined part of the robotic device to be draped. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] Patent No. 6806407 [Patent Document 2] Special Publication No. 2022-515864 Summary of the Invention [Problem to be solved by the invention]

[0010] The technology disclosed in Patent Document 1 has a problem in that when the bearing structure rotates, friction generated inside the bearing structure becomes resistance to the rotation of the arm of the surgical robot. Also, the technology disclosed in Patent Document 2 has a problem in that when the drape is fixed by a fixing element, the fixed drape may interfere with the rotation of the arm.

[0011] The present disclosure relates to a front drape that covers a front side of an arm unit and that can be arranged in an appropriate position without interfering with the operation of the arm unit. The present disclosure also relates to a drape set including the front drape. [Means for solving the problem]

[0012] A front drape which is one aspect of the present disclosure is a front drape which covers at least a portion of a front portion of a medical device having an arm unit including an arm portion and a front portion to which a medical device is connected and which is rotatably connected to the front side of the arm portion, the front drape including a bag portion formed of a sheet material having an opening, a bag opening which is the opening of the bag shape, a front fixing portion which is detachably attached to a front detachable portion provided on the front portion at a first end of a bottom portion of the bag portion opposite the bag opening, and a mark portion which is positioned a predetermined distance away from the front fixing portion in a direction toward a second end of the bottom portion opposite the first end, the mark portion being identifiable from the surrounding portions of the bag portion, and which is positioned at a predetermined location on the front portion, and which is sandwiched between the medical device and the front portion when the medical device is connected.

[0013] With the leading drape configured in this manner, the operator can place the leading drape in an appropriate position by attaching the leading fixed part to the leading detachable part and placing the mark part at a predetermined location on the leading part. In addition, since the mark part is sandwiched between the medical instrument and the leading part and fixed to the leading part, the leading drape can be maintained in an appropriate position. In other words, the leading drape can be placed in an appropriate position that does not interfere with the operation of the leading part, and the leading drape can be maintained in an appropriate position.

[0014] In one aspect of the present disclosure, the front drape preferably includes a contraction portion near the bag-shaped opening that contracts the surrounding portion in a direction along the edge of the bag-shaped opening.

[0015] According to the front drape configured in this manner, the bag-shaped opening is contracted in a direction along its edge by the contraction portion. When the front side portion is inserted through the bag-shaped opening and disposed inside the bag-shaped portion, the bag-shaped opening is in contact with the corresponding portion of the front side portion. At this time, the bag-shaped opening comes into contact with the corresponding portion in a state in which it has been contracted by the contraction portion to a size corresponding to the corresponding portion of the front side portion. The state in which the bag-shaped opening has been contracted to a size corresponding to the corresponding portion of the front side portion is maintained by the contraction portion. Therefore, the front drape can appropriately separate the portion of the front side portion disposed inside it from the outer area of ​​the outer drape.

[0016] In one aspect of the present disclosure, the tip fixing part preferably has a rod shape extending in a direction from the first end toward the second end.

[0017] With the front drape configured in this manner, when the front fixed part is attached to the front detachable part, the surrounding part of the front drape is fixed linearly to a predetermined location on the front part along the extension direction of the rod-shaped front fixed part. Also, since it is arranged in a direction from the first end to the second end of the bottom part, it is unlikely to get in the way when wrapping or folding the front drape.

[0018] A drape set according to one aspect of the present disclosure includes any of the above-described front drapes and an arm drape that covers at least a portion of the arm portion.

[0019] With the drape set configured in this manner, the arm drape, which is a drape material covering the arm portion, and the front drape, which is a drape material covering the front portion, are configured as separate bodies, so that the generation of unnecessary friction when the front portion rotates is suppressed. In other words, because no configuration such as a bearing structure is provided between the arm drape and the front drape, the generation of unnecessary friction between the arm drape and the front drape is suppressed, and the hindrance of the rotational movement of the front portion is suppressed. Effect of the Invention

[0020] According to the front drape of the present disclosure, it is possible to place the front drape at an appropriate position and to maintain the state in which the front drape is placed at the appropriate position. [Brief description of the drawings]

[0035] As shown in Figs. 2 to 5 etc., the tip portion 21 is provided with an arm attachment / detachment portion 23 into which an arm fixing portion 230, the details of which will be described later, is detachably fitted. As shown in Figs. 2 to 5 etc., the arm attachment / detachment portion 23 is a groove extending in the up-down direction (Y1Y2 direction in Figs. 3 to 5) having a shape corresponding to the cylindrical arm fixing portion 230. The arm attachment / detachment portion 23 is a groove having a shape to which the cylindrical arm fixing portion 230 can be detachably attached. The arm attachment / detachment portion 23 may have a shape different from that shown in Figs. 2 to 5 etc., as long as the arm fixing portion 230 can be detachably attached.

[0036] As shown in Figures 3 to 5, the tip portion 15 includes a holder portion 16 and a rotating portion 17. As shown in Figures 2 to 4 and 16, the holder portion 16 is a portion to which an endoscope 70 is connected. As shown in Figures 3 and 4, the holder portion 16 includes a holder main body 16A, a holder detachable portion 16B, and a holder base portion 16C.

[0037] As shown in FIG. 5, the holder body 16A is connected to the rotating part 17 so as to be rotatable about the axis HA. The rotatable direction of the holder body 16A is indicated by an arrow in FIG. 5. The axis HA is an axis that passes through a predetermined position of the rotating part 17 and extends in a direction intersecting with the axis VA2. As shown in FIG. 3 to FIG. 5 and the like, the front side of the holder body 16A (the side of X1 in FIG. 3 to FIG. 5) is provided with the front side detachable part 25. The front side detachable part 25 is a part to which the front side fixed part 330, the details of which will be described later, is detachably connected. The front side detachable part 25 is a groove that extends in the same direction as the axis HA. The front side detachable part 25 is a groove that has a shape that allows the front side fixed part 330 to be detachably attached. The front side detachable part 25 may have a shape different from the shape shown in FIG. 3 to FIG. 5 and the like as long as the front side fixed part 330 can be detachably attached.

[0038] As shown in Figures 3-4 and 16, the holder detachable part 16B and the holder base part 16C are parts for fixing the endoscope 70 to the holder main body 16A. The holder detachable part 16B and the holder base part 16C sandwich and fix the main body 71 of the endoscope 70 between them. The holder detachable part 16B is detachably fixed to the holder base part 16C with the main body 71 sandwiched between the holder detachable part 16B and the holder base part 16C.

[0039] As shown in Figs. 3 to 5, the holder base 16C is connected to the lower side 16E of the holder main body 16A so as to be slidable. The holder base 16C is connected to the lower side 16E so as to be slidable in the direction indicated by the arrow S in Figs. 3 to 4 (X1-X2 directions in Figs. 3 to 4). The holder base 16C is connected to the lower side 16E so as to be slidable from the use position P1 toward the retracted position P2. The holder base 16C is also connected to the lower side 16E so as to be slidable from the retracted position P2 toward the use position P1. The use position P1 is a position where the holder base 16C is disposed when the endoscope 70 is used. The retracted position P2 is a position where the holder base 16C is disposed when the endoscope 70 is retracted to the proximal side by a retraction function, the details of which will be described later.

[0040] The holder section 16 has a retraction function of retracting the connected endoscope 70 to the proximal side (the base side) in accordance with the operation of the user. More specifically, the holder section 16 has a function of quickly moving the arrangement position of the holder base section 16C from a use position P1 to a retracted position P2 in accordance with the operation of the user.

[0041] The retraction function is a function for quickly moving the arrangement position of the holder base 16C from the use position P1 to the retracted position P2, thereby withdrawing the insertion section 72 at the tip side of the endoscope 70 to the outside of the patient. This retraction function is activated by the user's operation, for example, when the patient moves while the insertion section 72 is inserted into the patient.

[0042] When the retraction function is activated, the holder base 16C is rapidly moved from the use position P1 to the retracted position P2 by tension of a spring or the like. The holder base 16C may be configured to rapidly move from the use position P1 to the retracted position P2 by other means. Figures 3, 5, 14, and 16 show the holder base 16C in the retracted position P2. Figure 4 shows the endoscope 70 in the use position P1.

The axis line VA2 is an axis line that passes through a predetermined part of the tip part 21 and extends in the vertical direction (Y1Y2 direction in Figs. 3 and 4). The rotating part 17 is provided with a cylindrical rotating base 17A on the tip part 21 side. The rotating base 17A is connected to the tip part 21 via the joint part 19. The rotating base 17A is provided with a groove 17B along its side surface as shown in Figs. 3 to 5 and the like. The groove 17B is a portion into which a contracting part 325 of the front drape 300, the details of which will be described later, is fitted and attached.

[0044] As shown in Figs. 3, 4, 5, 15, etc., there is a gap between the tip side portion 15 and the arm portion 10. Specifically, as shown in Figs. 3, 4, etc., there is a gap between an upper side surface 17C, which is a surface facing the tip portion 21 of the rotating base portion 17A, and a lower side surface 21C, which is a surface facing the rotating portion 17 of the tip portion 21. A part of the joint portion 19 is exposed from the gap between the upper side surface 17C and the lower side surface 21C. Hereinafter, the part of the joint portion 19 exposed between the upper side surface 17C and the lower side surface 21C is also referred to as a connection portion 19A.

[0045] 2.Drape set description Next, the drape set 100 according to the present disclosure will be described.

[0046] The drape set 100 of the present disclosure includes an arm drape 200, a front drape 300, and an auxiliary drape 400 (see Figs. 2, 12, 13, etc.). The arm drape 200, the front drape 300, and the auxiliary drape 400 are each made of a flexible sheet material formed into a predetermined shape.

[0047] 2-1. Arm drapes As shown in Fig. 2, 13 to 16, etc., the arm drape 200 is a drape material that covers a part of the tip side of the arm section 10. The arm drape 200 is a drape material that covers the area from the tip section 21 of the arm section 10 to a part between the joints 13A and 13B in the arm part 11B. The arm drape 200 has a size that can cover the arm part 11A, the joint 13A, and at least a part of the tip side of the arm part 11B. In other words, the arm drape 200 has a size that can cover a part of the tip side (distal side) of the arm section 10 that may come into contact with an operator or a user of the endoscope holding device 1.

[0048] Hereinafter, the area on the tip side of the arm section 10 covered by the arm drape 200 will also be referred to as the tip side area 10A. That is, the area from the tip end 21 to a predetermined position between the joint 13A and the joint 13B of the arm part 11B will also be referred to as the tip side area 10A (see FIG. 2). The range of the tip side area 10A is not limited to the above range, so long as it is a range on the tip side (distal side) of the arm section 10 that may be touched by an operator or a user of the endoscope holding device 1.

[0049] The arm drape 200 is a colorless, transparent, and flexible sheet material 201 formed into a tubular shape. The tip portion of the arm drape 200 is formed into an L-shape as shown in Fig. 6. The arm drape 200 includes a main body portion 210, a proximal opening 270, and a distal opening 260.

[0050] The distal opening 260 is a portion where an opening 260A is formed on the tip side (X1 side in FIG. 6) of the main body portion 210. The distal opening 260 is a region in the vicinity of the edge portion 260C between the end a on the front side (X1 side in FIG. 6) of the linear joint 240L and the end on the lower side (Y2 side in FIG. 6) of the linear joint 280L, and is a portion surrounded by virtual lines K1 and K2. The virtual line K1 is a virtual straight line that passes through the end 230A on the lower side (Y2 side in FIG. 6) of the arm fixing portion 230, the details of which will be described later, and extends parallel to the edge portion 260C. The virtual line K2 is a virtual straight line that passes through the end a and extends in a direction intersecting with the edge portion 260C.

[0051] The proximal opening 270 is a portion where an opening 270A is formed on the base side (the X2 side in FIG. 6) of the main body portion 210. The proximal opening 270 is a portion near the side portion 270B in FIG. 6, and is a portion between the side portion 270B and a line portion 270C extending parallel to the side portion 270.

[0052] 6 shows arm drape 200 folded flat such that the inner surfaces of the cylindrical shapes are in contact with each other. That is, FIG. 6 shows one side of arm drape 200 folded flat. Hereinafter, the portion of sheet material 201 appearing on the front side of the paper in FIG. 6 will also be referred to as sheet material 201A. Also, the portion of sheet material 201 that has the same shape as sheet material 201A and is disposed on the back side of the paper in FIG. 6 will also be referred to as sheet material 201B. That is, FIG. 6 shows a state in which arm drape 200 is folded and sheet material 201A and sheet material 201B are overlapped flat.

[0053] In FIG. 6, the sheet material 201A and the sheet material 201B are connected at least at the side portion 210A and the side portion 210B. The sheet material 201A and the sheet material 201B are connected at a linear joint 220L that extends in the same direction as the side portion 220B near the side portion 220B. The sheet material 201A and the sheet material 201B are connected at a linear joint 240L that extends in the same direction as the side portion 240B near the side portion 240B. The sheet material 201A and the sheet material 201B are connected at a linear joint 245L that extends from an end a of the linear joint 240L toward an end b located above the end a (Y1 side in FIG. 6). The linear joint 220L and the linear joint 240L are connected at the intersection. The sheet material 201A and the sheet material 201B are joined at a linear joint 280L that extends in the same direction as the end side 280, near the end side 280 that extends in a direction intersecting with the edge portion 260C.

[0054] 6, sheet material 201A and sheet material 201B are not joined at proximal opening 270. Moreover, sheet material 201A and sheet material 201B are not joined at distal opening 260. Moreover, sheet material 201A and sheet material 201B are not joined or connected in the area surrounded by sides 210A and 210B, linear joints 280L, 245L, 240L, and 220L, and side 270B.

[0055] In the proximal opening 270, when the sheet material 201A is pulled toward the front side of the paper in FIG. 6 and the sheet material 201B is pulled toward the back side of the paper in FIG. 6 to separate the sheet material 201A and the sheet material 201B, an opening 270A is formed between the sheet material 201A and the sheet material 201B (see FIG. 11, etc.). Hereinafter, separating the overlapped sheet materials to form an opening therebetween is also referred to as opening. Also, a state in which the overlapped sheet materials are separated to form an opening is also referred to as an open state. The opening 270A is a portion into which the front side portion 15 and the front side region 10A are inserted when the arm drape 200 is disposed on the arm portion 10.

[0056] When the sheet materials 201A, 201B are opened at the distal opening 260, an opening 260A is formed as shown in Figures 14 to 16. The distal opening 260 is a portion inside which the connecting portion 19A and at least a part of the rotating base 17A are disposed when the arm drape 200 is disposed in the tip region 10A (see Figures 14 to 16, etc.). The distal opening 260 is provided at a position corresponding to the connecting portion 19A.

[0057] The distal opening 260 is configured to form an opening 260A large enough to allow the tip side portion 15 and the tip side region 10A to pass through. That is, the linear joints 240L and 245L are each provided so as to form an opening 260A large enough to allow the tip side portion 15 and the tip side region 10A to pass through.

[0058] In Fig. 6, the linear joint 245L extends obliquely from the end a of the linear joint 240L toward the upper side (Y1 side in Fig. 6). On the other hand, the linear joint 245L may extend from the end a toward the upper side (Y1 side in Fig. 6) in a direction different from the above, as long as it can form an opening 260A large enough to pass the tip side portion 15 and the tip side region 10A when the distal opening 260 is opened. In other words, the end b of the linear joint 245L may be disposed at a position different from that shown in Fig. 6, as long as it is a position where an opening 260A large enough to pass the tip side portion 15 and the tip side region 10A can be formed when the distal opening 260 is opened, and is a position above the linear joint 240L.

[0059] Hereinafter, the region of arm drape 200 behind linear joint 220L (X2 side in FIG. 6) will be referred to as original side portion 220. In addition, the portion extending from upper region 220A, which is a region where sheet material 201A and sheet material 201B are not joined, on the front side (X1 side in FIG. 6) of original side portion 220 toward the front side (X1 side in FIG. 6) will be referred to as tip side portion 240.

[0060] The tip side portion 240 is a portion that is arranged on the tip side of the tip region 10A when the arm drape 200 is arranged on the arm section 10. Specifically, it is a portion that is arranged so as to cover at least a part of the tip side of the arm part 11A. The base side portion 220 is a portion that is arranged on the base side of the tip region 10A when the arm drape 200 is arranged on the arm section 10. Specifically, it is a portion that is arranged on the base side of the arm part 11A or on the arm part 11B.

[0061] As shown in FIG. 6, the front side of the tip side portion 240 (the X1 side in FIG. 6) is provided with a protruding portion 240A that protrudes forward (the X1 side in FIG. 6) from the end side 280. This protruding portion 240A is provided with an arm fixing portion 230. The arm fixing portion 230 is a cylindrical resin tube having a size that allows it to be detachably attached to the arm detachable portion 23. The arm fixing portion 230 may be formed of another material into a cylindrical shape. The arm fixing portion 230 may have a shape other than a cylindrical shape as long as it has a shape that allows it to be detachably attached to the arm detachable portion 23.

[0062] The arm fixing part 230 is sandwiched between the sheet material 201A and the sheet material 201B, and the peripheral part is linearly attached and fixed to the protruding part 240A. The arm fixing part 230 may be fixed to the protruding part 240A by other methods.

[0063] The arm fixing part 230 is disposed so that the distance between the end 230A on the lower side (Y2 side in FIG. 6) and the edge part 260C in the vertical direction (Y1Y2 direction in FIG. 6) is a predetermined distance G. That is, the arm fixing part 230 is disposed so that the position of the end 230A in the vertical direction (Y1Y2 direction) is a predetermined distance G along the end side 280 from the end of the front side (X1 side in FIG. 6) of the edge part 260C. The distance G is a length at which the edge part 260C is disposed on the front side part 15 side from the connection part 19A when the arm fixing part 230 is attached to the arm detachable part 23 so that the end 230A is at the same position as the end face 23A of the arm detachable part 23 (see FIG. 15). The end face 23A is the end face on the lower side (Y2 side in FIGS. 3 to 5) of the arm detachable part 23.

[0064] Arm fixing portion 230 is disposed on protruding portion 240A so that the height direction of the cylindrical shape is the same as the extending direction of end side 280. In other words, arm fixing portion 230 is disposed on protruding portion 240A so that the extending direction of arm fixing portion 230 is the direction intersecting with edge portion 260C.

[0065] 15 and the like, the distal opening 260 is formed so that when it is disposed on the arm section 10, its inner portion and edge portion 260C do not come into contact with the front drape 300 disposed on the front side section 15. The distal opening 260 has a size that allows the formation of an opening 260A of a size that does not allow its inner portion and edge portion 260C to come into contact with the front drape 300 disposed on the front side section 15 when it is disposed on the arm section 10. In other words, the linear joint 240L and the linear joint 245L are provided so that a distal opening 260 of such a size is formed.

[0066] As shown in Fig. 6, the arm drape 200 is provided with band-shaped fixing tapes 250A, 250B extending in the up-down direction (Y1Y2 direction in Fig. 6). As shown in Fig. 16, the fixing tapes 250A, 250B are used to fix the arm drape 200 by wrapping them around the arm parts 11A, 11B, etc. after the arm drape 200 is placed in the front region 10A.

[0067] The arm drape 200 has a size that allows the tip side part 15 to be inserted from the opening 270A of the proximal opening 270 and the tip side region 10A of the arm unit 5 to be disposed inside the tip side part 220. That is, the base side part 220 has a size that allows the tip side part 15 inserted from the proximal opening 270 and the tip side region 10A of the arm unit 5 to pass toward the tip side part 240 and the base side (proximal side) part of the tip side region 10A to be disposed inside the tip side part 220. The tip side part 240 has a size that allows the tip side part 15 inserted through the base side part 220 to be inserted close to the end side 280 and further passed through the opening 260A of the distal opening 260 to be disposed outside the arm drape 200. The tip side part 240 has a size that allows the tip side part of the tip side region 10A inserted inside the tip side part 220 to be disposed inside the tip side part 220.

[0068] 2-2. About the front drape 2, 11 to 16, etc., the front drape 300 is a drape material that covers the front portion 15. The front drape 300 is a colorless, transparent, and flexible sheet material 301 formed into a bag shape.

[0069] As shown in Fig. 7, the front drape 300 includes a bag-shaped portion 310 and a bag opening 320 which is an opening of the bag-shaped portion. Fig. 7 shows the front drape 300 folded flat with the inner surfaces of the bag-shaped portions in contact with each other. That is, Fig. 7 shows one side of the front drape 300 folded flat. For the sake of explanation, Fig. 7 shows a state in which the contraction portion 325, the details of which will be described later, is not contracted. That is, the bag opening 320 is shown in a state in which it is not contracted by the contraction portion 325.

[0070] Hereinafter, the portion of sheet material 301 appearing on the front side of the paper in Fig. 7 will also be referred to as sheet material 301A. Also, the portion of sheet material 301 that has the same shape as sheet material 301A and is disposed on the back side of the paper in Fig. 7 will also be referred to as sheet material 301B. That is, Fig. 7 shows a state in which front drape 300 having a bag-like shape is folded flat and sheet material 301A and sheet material 301B are overlapped.

[0071] In Fig. 7, sheet material 301A and sheet material 301B are connected at side portion 310A, side portion 310B, and side portion 310C. In Fig. 7, sheet material 301A and sheet material 301B are not connected or joined at any other portions than those mentioned above.

[0072] The bag opening 320 is a portion where the opening 320A is formed. The bag opening 320 has a size that allows the opening 320A to be formed so that the front side part 15 can pass through. The bag-shaped part 310 has a size that allows the front side part 15 to be arranged inside it. Furthermore, the bag-shaped part 310 has a size that does not interfere with the operation of the holder part 16 arranged inside it. For example, the bag-shaped part 310 has a sufficient size so that when the holder main body 16A performs a rotational operation, a part of the holder main body 16A does not get caught on the bag-shaped part 310, and the movement is not hindered. Furthermore, the bag-shaped part 310 has a sufficient size so that it does not interfere with the operation of the holder part 16 arranged inside it by the retraction function, which will be described in detail later.

[0073] Bag opening 320 is a portion formed by folding back sheet material 301 at edge portion 320B toward side portion 310C. Side portion 320C on the end side of this folded back sheet material 301 is joined to the sheet material 301 on the overlapping side.

[0074] Bag opening 320 is provided with linear contraction portion 325 along edge portion 320B near edge portion 320B. Contraction portion 325 is sandwiched and disposed between sheet material 301 constituting bag-shaped portion 310 and sheet material 301 folded back at edge portion 320B. Contraction portion 325 is a linearly formed contractile rubber material, and is a portion that contracts bag opening 320 in the direction along edge portion 320B.

[0075] Contraction portion 325 may be made of a material other than rubber as long as it can shrink bag opening 320 in the direction along edge portion 320B. Alternatively, contraction portion 325 may be made of a material that does not have contraction properties as long as it can shrink bag opening 320 in the direction along edge portion 320B. For example, contraction portion 325 may be made of a string made of a material that does not have contraction properties. Then, both ends of the string may be pulled to contract bag opening 320.

[0076] 7, the front drape 300 is provided with a front fixed part 330 at an end 370B. The end 370B is an end part on the side of the side 310B of the bottom part 370 on the bottom side of the bag-shaped part 310. The bottom part 370 is a region in the vicinity of the side part 310C, and is a part that becomes the bottom side of the bag-shaped part 310. The end 370B is an example of a first end part.

[0077] The front fixed part 330 is a cylindrical resin tube having a size that allows it to be detachably attached to the front detachable part 25. The front fixed part 330 may be made of another material formed into a cylindrical shape. Furthermore, the front fixed part 330 may have another shape as long as it can be detachably attached to the front detachable part 25.

[0078] Front fixing part 330 is sandwiched between sheet material 301A and sheet material 301B and arranged at end 370B, and is fixed by bonding sheet material 301A and sheet material 301B around it. Front fixing part 330 may be fixed to end 370B by other methods.

[0079] Front fixed part 330 is disposed so that the height direction of its columnar shape is the same as the extending direction of bottom part 370. In other words, front fixed part 330 is disposed so that the extending direction is the same as the direction from end 370B toward end 370A of bottom part 370 on the opposite side to end 370B. End 370A is an example of a second end.

[0080] The bottom 370 is provided with a mark portion 350. As shown in FIG. 7 and the like, the mark portion 350 is disposed at a position spaced apart from the front fixed portion 330 by a predetermined distance L1 along the first bag-shaped portion 310 in the direction of the end portion 370A. Specifically, the mark portion 350 is disposed at a position where the distance between the mark portion 350 and the center of the height direction of the cylindrical shape of the front fixed portion 330 in the direction in which the side portion 310C extends is the distance L1. The distance L1 is equal to or longer than the distance L2 (see FIG. 5) between the front detachable portion 25 and the holder bottom portion 16D when the holder base portion 16C is disposed in the retracted position P2.

[0081] The mark portion 350 is a portion used as a mark for appropriately positioning the front drape 300 with respect to the front portion 15. The mark portion 350 is configured so that a user can visually distinguish the mark portion 350 from the surrounding portion. To be more specific, the mark portion 350 is a portion where a predetermined portion of the bottom portion 370 is coated with a non-translucent paint. The mark portion 350 may be provided at a predetermined portion of the front drape 300 by other methods as long as the mark portion 350 can be visually distinguished from the surrounding portion.

[0082] 2-3. Auxiliary drapes The auxiliary drape 400 is a drape material used when placing the arm drape 200 and the front drape 300 on the arm unit 5, as shown in FIGS.

[0083] As shown in Fig. 8, the auxiliary drape 400 is a flexible sheet material 401 formed into a tubular shape. Fig. 8 shows the auxiliary drape 400 folded flat with the inner surfaces of the tubular shape in contact with each other. That is, Fig. 8 shows one side of the auxiliary drape 400 folded flat.

[0084] Hereinafter, the portion of sheet material 401 appearing on the front side of the paper in Fig. 8 will also be referred to as sheet material 401A. Also, the portion of sheet material 401 that has the same shape as sheet material 401A and is arranged on the back side of the paper in Fig. 8 will also be referred to as sheet material 401B. That is, Fig. 8 shows sheet material 401A and sheet material 401B stacked in a plane.

[0085] In Fig. 8, sheet material 401A and sheet material 401B are connected at side portion 410A and side portion 410B. In Fig. 8, sheet material 401A and sheet material 401B are not connected or joined at any other portions than those mentioned above.

[0086] The auxiliary drape 400 includes a tubular portion 410, a distal opening 460, and a proximal opening 470. The distal opening 460 is a portion where an opening 460A is formed. The proximal opening 470 is a portion where an opening 470A is formed. The tubular portion 410 is a portion that has a tubular shape and has openings 460A and 470A.

[0087] The auxiliary drape 400 has a size that allows the leading side portion 15 and the leading region 10A to be inserted through the proximal opening 470 and the leading region 10A and the leading side portion 15 to be disposed inside and covered. The distal opening 460 has a size that allows the leading side portion 15 and the leading region 10A to pass through the inside of the distal opening 460. That is, the auxiliary drape 400 is configured so that the distal opening 460 can be pulled close to the proximal opening 470 from a state in which the leading region 10A and the leading side portion 15 are disposed inside the auxiliary drape 400.

[0088] Unlike sheet material 201 and sheet material 301, sheet material 401 is made of a colored material. Sheet material 401 has a color that allows auxiliary drape 400 to be identified when auxiliary drape 400 is placed below arm drape 200 and visually confirmed from the arm drape 200 side. Also, sheet material 401 has a color that allows auxiliary drape 400 to be identified when auxiliary drape 400 is placed below front drape 300 and visually confirmed from the arm drape 200 side.

[0089] The auxiliary drape 400 is provided to a user with the side of the distal opening 460 of the auxiliary drape 400 inserted inside the leading drape 300 as shown in Fig. 9. Specifically, the auxiliary drape 400 is packaged together with the leading drape 300 with the side of the distal opening 460 narrowed and the narrowed portion of the distal opening 460 side inserted inside the leading drape 300, and provided to a user. Fig. 9 shows the auxiliary drape 400 with the side of the distal opening 460 narrowed and the leading drape 300 with the bag opening 320 contracted by the contraction portion 325. By providing the auxiliary drape 400 with the side of the distal opening 460 inserted inside the leading drape 300, the worker can perform the draping work appropriately.

[0090] The sheet material 201 and the sheet material 301 are made of a material that has a predetermined flexibility and has a translucency that allows the sheet material 401 arranged below to be identified. The sheet material 201 and the sheet material 301 may be made of a translucent material as long as the sheet material 201 and the sheet material 301 have a predetermined flexibility and have a translucency that allows the sheet material 401 arranged below to be identified.

[0091] Alternatively, the sheet material 201 and the sheet material 301 may be made of a material having a different color as long as the sheet material 401 arranged below can be distinguished from each other. For example, the sheet material 201 and the sheet material 301 may be made of a material having a different color from the sheet material 401, which allows the sheet material 401 arranged below to be distinguished from each other.

[0092] The sheet material 201 may be made of a material different from the sheet material 301, so long as the material has a certain degree of flexibility and is translucent enough to allow the sheet material 401 placed underneath to be identified.

[0093] 3. Draping method explanation Next, a draping method for the endoscope holding device 1 using the drape set 100 of the present disclosure will be described with reference to Figs. 10 to 17. An operator who drapes the endoscope holding device 1 performs the work by cleaning at least his / her own hands and fingers after washing and / or disinfecting them. Alternatively, the operator performs the work while wearing clean gloves. The drape set 100 used for draping is provided to the operator in a clean state after sterilization or the like.

[0094] First, the auxiliary drape 400 is used to cover the front side portion 15 and the front side region 10A of the arm unit 5 (S10: first arrangement step). Specifically, the proximal opening 470 is opened to form an opening 470A. Then, the front side portion 15 is inserted from the opening 470A, so that the front side portion 15 and the front side region 10A are arranged inside the tubular portion 410.

[0095] 9, the auxiliary drape 400 is provided with its distal opening 460 side disposed inside the leading drape 300. The worker performs the above operations while keeping the distal opening 460 side of the auxiliary drape 400 inserted inside the leading drape 300.

[0096] 10, when the front side portion 15 is positioned near the bag opening 320 of the front side drape 300, the portion of the auxiliary drape 400 on the side of the proximal opening 470 is moved to the base side of the front side region 10A. That is, the area from the front side portion 15 to the front side portion of the arm part 11B is covered by the auxiliary drape 400. In other words, the front side portion 15 and at least a part of the front side area of ​​the front side region 10A are covered by the auxiliary drape 400.

[0097] Next, the front drape 300 is placed on the front portion 15 (S20: second placement step). Specifically, the bag opening 320 is widened by pushing and spreading the contracted portion 325 to form an opening 320A. Then, as shown in FIG. 11, the front portion 15 is inserted into the formed opening 320A so that the entire front portion 15 is placed inside the bag-shaped portion 310.

[0098] Once the entire front portion 15 is positioned inside the bag-shaped portion 310, the position of the front drape 300 is adjusted. Specifically, as shown in Fig. 11, the position of the front drape 300 is adjusted so that the portion around the contracted portion 325 of the bag opening 320 is positioned at the rotating base 17A.

[0099] Next, the arm drape 200 is placed (S30: third placement step). That is, the front region 10A is covered using the arm drape 200. Specifically, as shown in FIG. 11, the proximal opening 270 of the arm drape 200 is opened to form an opening 270A. Then, the front side portion 15 covered with the front drape 300 and the auxiliary drape 400 is inserted into the inside of the arm drape 200 through the formed opening 270A. When the front side portion 15 is inserted close to the end side 280 of the tip side portion 240, the front side portion 15 is passed through the opening 260A of the distal opening 260 and placed outside the arm drape 200 as shown in FIG. 12. That is, the front side portion 15 covered with the front drape 300 and the auxiliary drape 400 is placed outside the arm drape 200.

[0100] At this time, the proximal opening 270 of the arm drape 200 is disposed near the joint 13A as shown in Fig. 12. That is, the area from the tip end 21 of the arm part 11A to the base side is covered with the arm drape 200.

[0101] Next, the auxiliary drape 400 is pulled out and moved to the proximal side (S40: pulling step). Specifically, the portion of the tubular portion 410 near the proximal opening 470 is pulled in the proximal direction to move the distal opening 460 to the proximal side.

[0102] When this is done, the leading side (the side of the distal opening 460) of the auxiliary drape 400 that is positioned inside the leading drape 300 slides between the leading drape 300 and the leading portion 15 and is pulled to the outside of the leading drape 300.

[0103] Furthermore, when the portion of tubular portion 410 near proximal opening 470 is pulled toward the base side, the tip portion of auxiliary drape 400 (the side of distal opening 460) is pulled toward the base side, sliding between tip region 10A and arm drape 200. That is, when the tip portion of auxiliary drape 400 is pulled toward the base side as if to pull the tip portion of auxiliary drape 400 toward the base side, the tip portion of auxiliary drape 400 is pulled toward the base side, sliding between tip region 10A and arm drape 200.

[0104] The tip side (the side of the distal opening 460) of the auxiliary drape 400 is pulled toward the base side so that the distal opening 460 is disposed closer to the base side than the tip portion 21. In this way, the part on the side of the distal opening 460 is prevented from coming into contact with the tip drape 300 disposed on the tip portion 15. In other words, the part on the side of the distal opening 460 is prevented from coming into contact with the tip drape 300 and interfering with the rotational movement of the tip portion 15.

[0105] 13, it is preferable that the tip side (the side of the distal opening 460) of the auxiliary drape 400 is disposed closer to the base side than the joint 13A. That is, it is preferable that the auxiliary drape 400 is disposed between the joint 13A and the joint 13B. In this way, the joint 13A is prevented from being doubly covered by the arm drape 200 and the auxiliary drape 400. That is, the auxiliary drape 400 is prevented from interfering with the rotational movement of the arm part 11A. The pulled-out auxiliary drape 400 may be stretched toward the base side and used as a drape material to cover the arm parts 11B and 11C.

[0106] Next, the position of the arm drape 200 is adjusted (S50: adjustment step). Specifically, the proximal opening 270 is moved to the base side so that the entire tip region 10A is covered with the arm drape 200. Furthermore, as shown in Fig. 14, the arm fixing part 230 is fitted into the arm attachment / detachment part 23 so that the tip side of the tip side part 240 is fixed to the tip part 21. When attaching the arm fixing part 230 to the arm attachment / detachment part 23, the end part 230A of the arm fixing part 230 is positioned at the same position as the end face 23A of the arm attachment / detachment part 23.

[0107] When the arm fixing part 230 is attached to the arm attachment / detachment part 23 and the position of the arm drape 200 is adjusted by smoothing out wrinkles, the edge part 260C is disposed on the front side part 15 side by a distance G from the end surface 23A of the arm attachment / detachment part 23. At this time, the edge part 260C is disposed on the front side part 15 side (the rotating base 17A side) of the connection part 19A. When the arm drape 200 is disposed in this manner, the connection part 19A and at least a part of the tip part 21 side of the rotating base 17A are surrounded by the distal opening 260 as shown in FIGS. 14 to 16.

[0108] Next, the position of the front drape 300 is adjusted (S60: front drape adjustment step). Specifically, as shown in Figs. 14 to 16, the position of the front drape 300 is readjusted so that the portion of the bag opening 320 near the contraction portion 325 is placed on the rotating base 17A. The contraction portion 325 is also positioned so as to be fitted into the groove 17B. The portion of the bag opening 320 near the contraction portion 325 is tightened by contraction of the contraction portion 325, so that it is maintained in contact with the surface of the rotating base 17A. Furthermore, the front fixing portion 330 is attached to the front detachable portion 25, so that the portion of the bag-shaped portion 310 around the front fixing portion 330 is fixed to the holder body 16A.

[0109] When adjusting the positions of the arm drape 200 and the front drape 300, the positions of each are adjusted so that the distal opening 260 does not come into contact with the front drape 300.

[0110] 16, the fixing tapes 250A and 250B are wound around the arm parts 11A and 11B to fix the arm drape 200 (S70: arm drape fixing step). That is, the fixing tapes 250A and 250B are wound around the arm parts 11A and 11B to prevent the base side part 220 and the tip side part 240 from getting in the way when the endoscope holding device 1 is used. At this time, the tip side part 240 is lifted in a direction away from the tip side part 15 to fix the arm drape 200. Specifically, the tip side part 240 is lifted so that the position of the proximal side (the side of the arm part 11A) of the edge part 260C in the up-down direction (the Y1Y2 direction in FIGS. 3 to 5) becomes the same as the position of the side of the arm fixing part 230 of the edge part 260C. That is, the proximal side of the edge portion 260C is arranged at a position unnecessarily lowered, and the edge portion 260C and the distal opening 260 are prevented from contacting the front drape 300 arranged on the front side portion 15. When the tip side portion 240 is lifted in a direction away from the front side portion 15, the linear joint portion 245L and its end portion b are prevented from contacting the arm part 11A, and the proximal side of the edge portion 260C (the side of the arm part 11A) is prevented from being arranged higher than necessary. That is, the tip side portion 240 is prevented from being lifted too much more than necessary, and the proximal side of the connection portion 19A is prevented from being exposed.

[0111] Next, the endoscope 70 is connected to the holder section 16 (S80: endoscope connecting step). When connecting the endoscope 70 to the holder section 16, as shown in FIG. 14, the mark section 350 is placed on the holder bottom section 16D. Then, with the mark section 350 placed on the holder bottom section 16D, the main body 71 of the endoscope 70 is placed on the holder bottom section 16D. Next, as shown in FIG. 16, the main body 71 is fixed by sandwiching it between the holder base section 16C and the holder detachable section 16B. The mark section 350 and a portion of the bag section 310 surrounding the mark section 350 are sandwiched between the holder bottom section 16D and the endoscope 70, and fixed to the holder base section 16C.

[0112] The end 370B of the front drape 300 configured as described above is fixed to the holder section 16 by the front fixing section 330. The portion of the end 370A opposite to the end 370B is sandwiched between the holder bottom section 16D and the main body 71 of the endoscope 70 and fixed to the holder section 16. Therefore, even if the holder section 16 performs a predetermined operation, the placed front drape 300 is unlikely to come off or its placement position is unlikely to shift or become displaced. That is, the state in which the front drape 300 is placed on the front section 15 is maintained.

[0113] Moreover, by attaching the front fixing part 330 to the front detachable part 25 and arranging the mark part 350 on the holder bottom part 16D, the front drape 300 can be arranged at an appropriate position. Therefore, when the holder part 16 performs a rotating operation, the front drape 300 can be arranged at an appropriate position where the front drape 300 does not interfere with the operation. In other words, a state in which the holder part 16 cannot perform a predetermined operation because the front drape 300 is not arranged appropriately and the holder part 16 is pulled by the front drape 300 is suppressed.

[0114] Furthermore, by arranging the mark portion 350 on the holder bottom portion 16D, the front drape 300 can be arranged in an appropriate position that does not interfere with the operation of the retraction function of the holder portion 16. In other words, the front drape 300 is prevented from being arranged in an appropriate position and hindering the operation of the retraction function of the holder portion 16. Specifically, the front drape 300 is prevented from being pulled by the fixed front drape 300 while the holder base portion 16C is moving due to the operation of the retraction function, and the movement operation is prevented from being hindered.

[0115] For example, if the front drape 300 is fixed without considering the distance L2 that the holder part 16C moves when the holder base part 16C is disposed at the use position P1, the holder part 16C may be pulled by the fixed front drape 300 while moving to the retracted position P2, and the movement may be hindered. Meanwhile, the mark part 350 of the front drape 300 is provided at a position away from the front fixing part 330 by a distance L1 toward the end part 370A. The distance L1 is equal to or longer than the distance L2 (see FIG. 4). Therefore, even if the holder base part 16C moves from the use position P1 to the retracted position P2, the front drape 300 does not hinder the movement.

[0116] That is, by arranging the mark portion 350 on the holder bottom portion 16D, the front drape 300 can be arranged and fixed at an appropriate position that does not interfere with the operation of the retraction function of the holder portion 16. For example, even when the holder base portion 16C is arranged at the use position P1, the front drape 300 can be arranged and fixed at an appropriate position.

[0117] A contraction portion 325 is provided near the bag opening 320 of the front drape 300. Therefore, the front drape 300 is placed on the front side portion 15 with its bag opening 320 contracted and in close contact with the rotating base 17A. The state in which the bag opening 320 is in close contact with the rotating base 17A of the rotating portion 17 is maintained by the contraction portion 325.

[0118] Therefore, the front drape 300 can separate the front portion 15 arranged inside thereof from the outer area of ​​the front drape 300. That is, the inner area of ​​the bag-shaped portion 310 that houses the front portion 15, which is an unclean area, is prevented from being connected to the outer clean area of ​​the front drape 300.

[0119] Since the front fixing part 330 has a rod-like shape extending in a direction from the end 370B toward the end 370A, the peripheral part of the front fixing part 330 is fixed linearly to the holder body 16A. Therefore, the peripheral part of the bottom part 370 along the front fixing part 330 comes into contact with the holder body 16A and is fixed linearly. That is, the front drape 300 is firmly fixed to the holder body 16A.

[0120] Furthermore, since the front fixing part 330 is disposed in the direction in which the bottom part 370 extends, it is unlikely to get in the way when the front drape 300 is folded or wrapped.

[0121] The arm drape 200 configured as described above is provided with the arm fixing portion 230 in the vicinity of the distal opening 260. This prevents the distal opening 260 from moving after the arm drape 200 is placed. For example, the arm drape 200 is prevented from moving due to the operation of the arm unit 5 or the like, causing the position of the distal opening 260 to change. This prevents the connection portion 19A, the tip portion 21, and the like from being exposed due to the position of the distal opening 260 being changed.

[0122] Moreover, the arm fixing part 230 is arranged so that its end 230A is located at a position that is a predetermined distance away from the edge part 260C along the end side 280. Therefore, when the arm fixing part 230 is attached to the arm attachment part 23, the edge part 260C is located at a predetermined position. More specifically, when the arm fixing part 230 is attached to the arm attachment part 23 so as to align the end part 230A with the position of the end surface 23A, the edge part 260C is located at a predetermined position. That is, when the arm fixing part 230 is attached to the arm attachment part 23, the distal opening 260 can be located at an appropriate position. The arm drape 200 can be maintained in a state of being precisely located with respect to the arm part 10.

[0123] Furthermore, when the arm fixing part 230 is attached to the arm detachable part 23, the edge part 260C is disposed on the side of the tip part 15 relative to the connection part 19A, and the connection part 19A is surrounded by the part of the distal opening 260 near the edge part 260C. This prevents the connection part 19A from being exposed. Furthermore, by simply attaching the arm fixing part 230 to the arm detachable part 23, the edge part 260C can be disposed in an appropriate position.

[0124] Since the arm fixing part 230 has a rod-like shape, the peripheral part of the arm fixing part 230 is linearly fixed to the tip part 21. Therefore, the peripheral part of the arm fixing part 230 of the arm drape 200 comes into contact with and is fixed to a predetermined part of the tip part 21. That is, the tip side part of the arm drape 200 (the tip side of the tip side part 240) is firmly fixed to the tip part 21.

[0125] Furthermore, when attaching the arm fixing part 230 to the arm attachment / detachment part 23, the attachment can be easily performed by attaching the arm fixing part 23 to the arm attachment / detachment part 23 from its end side. Furthermore, when removing the arm fixing part 230 from the arm attachment / detachment part 23, the removal can be easily performed by lifting the end side in a direction away from the tip part 21.

[0126] The arm fixing part 230 is arranged so that the direction in which its rod-like shape extends is the direction intersecting with the edge part 260C. Therefore, for example, compared to a case in which the tip side part 240 is fixed to the tip part 21 in a direction along the edge part 260C, the influence on the distal opening 260 is small when the arm fixing part 230 is attached. For example, the shape of the opening 260A is prevented from being significantly changed by attaching the arm fixing part 230 to the arm detachable part 23. Alternatively, after attaching the arm fixing part 230 to the arm detachable part 23, it is easy to further widen the opening 260A or adjust the position of the edge part 260C.

[0127] Furthermore, since the arm fixing part 230 is disposed to extend in the same direction as the axis line VA1, it is less susceptible to the rotational movement of the arm part 11A. That is, when the arm part 11A performs an operation of rotating about the axis line VA1, the arm fixing part 230 is prevented from coming off the arm attachment / detachment part 23.

[0128] Since the arm fixing part 230 is provided on the protruding part 240A, the work of attaching the arm fixing part 230 to the arm attachment / detachment part 23 can be easily performed. In other words, the tip side part of the tip side part 240 rarely interferes with the attachment of the arm fixing part 230, and the work of attaching the arm fixing part 230 to the arm attachment / detachment part 23 can be easily performed. In addition, when attaching the arm fixing part 230 to the arm attachment / detachment part 23, damage to the part of the tip side part 240 in the vicinity thereof is suppressed.

[0129] The drape set 100 configured as described above includes an arm drape 200 and a front drape 300. The arm drape 200, which is a drape material covering the arm portion 10, and the front drape 300, which is a drape material covering the front portion 15, are configured as separate bodies, and no bearing structure or other configuration is provided between them. For this reason, when the front portion 15 rotates, unnecessary friction between the arm drape 200 and the front drape 300 is suppressed. In particular, when an ophthalmic endoscope is used as the endoscope 70, since the insertion portion 72 is inserted into the patient's eyeball, it is not preferable that unnecessary friction occurs between the arm drape 200 and the front drape 300. If such friction inhibits the rotation of the front portion 15, even if only slightly, an unnecessary load may be applied to the patient. For example, friction may cause the rotational movement of the tip section 15 to be delayed, and the insertion section 72 may not be able to adequately follow the patient's movements, causing unnecessary force to be applied to the patient. On the other hand, the arm drape 200 and tip drape 300 of the present disclosure prevent such unnecessary load from being applied to the patient. Even when an endoscope of a type other than an ophthalmic endoscope is used as the endoscope 70, the insertion section 72 may prevent such unnecessary load from being applied to the patient.

[0130] The drape set 100 includes an auxiliary drape 400. By using the auxiliary drape 400 to cover the front side portion 15 and the front side region 10A, when placing the front side drape 300 on the front side portion 15, the worker is prevented from directly contacting the unclean areas such as the front side portion 15 and the front side region 10A. Also, when placing the arm drape 200 on the front side region 10A, the worker is prevented from directly contacting the unclean areas such as the front side portion 15 and the front side region 10A. That is, when draping the front side portion 15 and the front side region 10A, the worker is prevented from directly contacting the arm unit 5, which is an unclean area.

[0131] The distal opening 460 of the auxiliary drape 400 has a size that allows the formation of an opening 460A through which the front side portion 15 and the front side region 10A can pass. Therefore, with the front side portion 15 and the front side region 10A arranged inside the auxiliary drape 400, by pulling the part of the auxiliary drape 400 on the proximal opening 470 side toward the base side, the front side part (the distal opening 460 side) of the auxiliary drape 400 can be pulled toward the base side. That is, after the arm drape 200 and the front side drape 300 are arranged, the auxiliary drape 400 can be pulled toward the base side.

[0132] This prevents the auxiliary drape 400 from interfering with the operation of the arm unit 5. For example, the connection portion 19A is prevented from being doubly covered by the arm drape 200 and the auxiliary drape 400, which would hinder the rotational operation of the tip portion 15. Furthermore, by moving the distal opening 460 closer to the base side than the joint 13A, the joint 13A is prevented from being doubly covered by the arm drape 200 and the auxiliary drape 400, which would hinder the rotational operation of the arm part 11A.

[0133] Furthermore, the auxiliary drape 400 is formed from a sheet material 401 having a predetermined color, and the arm drape 200 and the front drape 300 are formed from transparent sheet materials 201, 301. In other words, the arm drape 200 and the front drape 300 are made from a material having translucency that allows the sheet material 401 arranged underneath to be identified.

[0134] Therefore, the worker can easily grasp the auxiliary drape 400 disposed between the arm drape 200 and the front region 10A. The worker can also easily grasp the auxiliary drape 400 disposed between the front portion 15 and the front drape 300. That is, the worker can easily pull out the auxiliary drape 400 to the base side. It is possible to provide a drape set 100 that allows the worker to easily perform draping work while preventing direct contact with an unclean area.

[0135] The technical scope of the present disclosure is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present disclosure. For example, the tip portion 21 may be provided with an arm detachable portion 23 that protrudes from the surface of the tip portion 21, and the arm fixing portion 230 may have a structure that allows it to be attached to the protruding arm detachable portion 23.

[0136] For example, the arm detachable part 23 may have a cylindrical shape protruding from the surface of the tip part 21, and the arm fixing part 230 may have a groove shape into which the arm detachable part 23 can be fitted. Alternatively, the arm fixing part 230 may have a structure that is attached to the arm detachable part 23 by sandwiching the protruding arm detachable part 23.

[0137] Alternatively, the holder body 16A may be provided with a leading-side detachable part 25 having a shape protruding from its surface, and the leading-side fixed part 330 may have a structure that allows it to be attached to the leading-side detachable part 25. For example, the leading-side detachable part 25 may have a cylindrical shape protruding from the surface of the holder body 16A, and the leading-side fixed part 330 may have a groove shape into which the leading-side detachable part 25 can be fitted. Alternatively, the leading-side fixed part 330 may have a structure that allows it to be attached to the leading-side detachable part 25 by sandwiching the leading-side detachable part 25.

[0138] In the above embodiment, the drape set 100 is described as being used for draping the endoscope holding device 1, but the drape set 100 may be used, for example, to cover an arm unit of a surgical robot. Alternatively, the drape set 100 may be used, for example, to cover an arm unit included in another medical device.

[0139] The present disclosure is not limited to the above-mentioned embodiments as long as it conforms to the gist of the disclosure described in the above-mentioned embodiments. Therefore, in the above-mentioned embodiments, any of the components illustrated or the components described with reference numerals may be eliminated.
