[0003] [Patent Document 1] Patent No. 5328253 Summary of the Invention [Problem to be solved by the invention]

[0004] It is desirable to more securely hold a medical device on a mount in a medical device holding structure.

[0005] The present disclosure aims to solve the above-mentioned problems. [Means for solving the problem]

[0006] (1) A first aspect of the present disclosure is a medical device holding structure comprising a medical device and a backing that holds the medical device, wherein the medical device comprises an outer tube, a first shaft that extends in the axial direction of the outer tube and is arranged inside the outer tube so as to be movable along the axial direction, a second shaft that extends along the first shaft and is arranged so as to be movable along the first shaft, a first gripping portion that is arranged at the base end of the outer tube, and a second gripping portion that is arranged at the base end of the first shaft and is arranged closer to the base end than the first gripping portion, and the backing comprises a backing body having a holding surface that holds the medical device, and a plurality of device holding portions that hold the medical device, and the plurality of device holding portions comprise a first intermediate holding portion that is arranged between the first gripping portion and the second gripping portion.

[0007] According to this medical device holding structure, the first intermediate holding portion of the device holding portion holds the area between the first holding portion and the second holding portion, thereby effectively preventing the medical device from detaching from the backing board during transport or when dropped.

[0008] (2) In the medical device holding structure described in (1) above, the multiple device holding portions may include a second intermediate holding portion that is arranged closer to the base end than the first intermediate holding portion, and the second gripping portion may be arranged between the first intermediate holding portion and the second intermediate holding portion.

[0009] With this configuration, the second gripping portion can be effectively positioned and held relative to the first gripping portion by the first intermediate holding portion and the second intermediate holding portion, which are respectively arranged on the distal end side and the proximal end side of the second gripping portion.

[0010] (3) In the medical device holding structure described in (2) above, when the medical device is held on the backing, the distance between the first gripping portion and the second gripping portion may be greater than or equal to the thickness of the backing.

[0011] With this configuration, the first gripping portion and the second gripping portion can be disposed close to each other by the first intermediate holding portion and the second intermediate holding portion, thereby making it possible to suppress bending of the second shaft.

[0012] (4) In the medical device holding structure described in (2) or (3) above, the first intermediate holding portion may include a first intermediate support piece erected on the holding surface of the base body, the first intermediate support piece having a first intermediate support hole that supports the first shaft, and the second intermediate holding portion may include a second intermediate support piece erected on the holding surface of the base body, the second intermediate support piece having a second intermediate support hole that supports the second shaft.

[0013] With this configuration, the first shaft can be effectively supported by the first intermediate support hole of the first intermediate support piece, and the second shaft can be effectively supported by the second intermediate support hole of the second intermediate support piece.

[0014] (5) In the medical device holding structure described in (4) above, the first gripping portion may have an outer diameter larger than an outer diameter of the second gripping portion.

[0015] This configuration allows the user to easily grip the first grip portion, and the user to easily operate the first shaft with the second grip portion.

[0016] (6) In the medical device holding structure described in (4) above, the diameter of the first intermediate support hole may be larger than the diameter of the second intermediate support hole, and the distance from the holding surface to the bottom of the second intermediate support hole may be larger than the distance from the holding surface to the bottom of the first intermediate support hole.

[0017] With this configuration, the outer cylinder and the first shaft can be held substantially parallel to the holding surface.

[0018] (7) In the medical device holding structure described in (4) above, the device holding portion has a plurality of hooks that protrude from the base body and hold the outer tube, and the hooks have a fixed end supported by the base body and a free end provided opposite the fixed end, and cover the outer tube between the fixed end and the free end, and when viewed from a direction perpendicular to the holding surface, the outer tube may be positioned between the fixed end and the free end.

[0019] With this configuration, the outer cylinder is held by the multiple hooks, and the medical device can be held effectively by cooperation between the multiple device holding portions and the multiple hooks.

[0020] (8) In the medical device holding structure described in (1) above, the medical device may have an expandable and contractible expansion body arranged at the tip of the first shaft, and the backing may have a cover portion connected to the backing body and covering the expansion body of the medical device.

[0021] With this configuration, the expansion body can be covered and protected by the cover portion, so that the expansion body can be held in a state where it is exposed to the outside of the outer tube.

[0022] (9) A second aspect of the present disclosure is a backing for holding a medical device having an outer tube, a first shaft extending in the axial direction of the outer tube and arranged inside the outer tube so as to be movable along the axial direction, a second shaft extending along the first shaft and arranged so as to be movable along the first shaft, a first holding portion arranged at the base end of the outer tube, and a second holding portion arranged at the base end of the first shaft, wherein the backing has a backing body having a holding surface for holding the medical device, and a plurality of device holding portions for holding the medical device, wherein the plurality of device holding portions include a first intermediate holding portion arranged between the first holding portion and the second holding portion.

[0023] According to this mount, the first intermediate holding portion of the equipment holding portion holds the medical equipment between the first gripping portion and the second gripping portion, thereby effectively preventing the medical equipment from coming off the mount during transport or when dropped.

[0024] (10) In the mount described in (9) above, the plurality of device-holding portions may include a second intermediate holding portion disposed closer to the base end than the first intermediate holding portion.

[0025] With this configuration, the second gripping portion can be effectively positioned and held relative to the first gripping portion by the first intermediate holding portion and the second intermediate holding portion arranged on the distal end side and proximal end side of the second gripping portion.

[0026] (11) In the mount described in (10) above, the first intermediate holding portion includes a first intermediate support piece that stands on the holding surface of the mount body and holds the medical device, and the second intermediate holding portion includes a second intermediate support piece that stands on the holding surface of the mount body and holds the medical device, the first intermediate support piece being cut and raised from the mount body toward the base end and protruding from the holding surface, and the second intermediate support piece being cut and raised from the mount body toward the tip end so as to approach the first intermediate support piece and protruding from the holding surface.

[0027] With this configuration, the distal end and proximal end of the second gripping portion can be effectively held by the first and second intermediate support pieces that protrude upright from the holding surface. Compared to a configuration in which the first and second intermediate support pieces are cut and raised in the same direction, a force acts on the first and second intermediate support pieces to return them to the holding surface of the backing, so that the first intermediate support piece applies a pressing force to the first gripping portion, and the second shaft inserted into the first gripping portion can be held as if it is being pulled in the distal direction.

[0028] (12) A third aspect of the present disclosure is a medical device package comprising a medical device holding structure including a medical device and a mount that holds the medical device, a packaging bag that houses the medical device holding structure, and a packaging box that houses the packaging bag, wherein the medical device has an outer tube, a first shaft that extends in the axial direction of the outer tube and is arranged inside the outer tube so as to be movable along the axial direction, a second shaft that extends along the first shaft and is arranged so as to be movable along the first shaft, a first gripping portion that is arranged at the base end of the outer tube, a second gripping portion that is arranged at the base end of the first shaft, and an expandable and contractible expansion body that is arranged at the tip end of the first shaft, and the mount comprises a mount main body having a holding surface that holds the medical device, a plurality of device holding portions that hold the medical device, and a cover portion that is connected to the mount main body and covers the expansion body of the medical device, the plurality of device holding portions include an intermediate holding portion disposed between the first gripping portion and the second gripping portion; the packaging bag includes a storage portion in which the medical device holding structure is stored, a first bag end provided on one end side of the storage portion and opened when the medical device holding structure is removed from the storage portion, and a second bag end having a pair of corners and being a closed end provided on the other end side of the storage portion; when the medical device holding structure is stored in the packaging bag, the cover portion covering the expandable body is stored inside the second bag end, and in the thickness direction of the packaging bag perpendicular to the extension direction of the packaging bag, the thickness of the second bag end is greater than the thickness of the first bag end; the packaging bag is stored in the packaging box with the pair of corners folded in directions approaching each other, and the pair of folded corners contact the longitudinal ends of the packaging box.

[0029] According to this medical device package, a pair of corners of the packaging bag function as cushioning material inside the packaging box, thereby effectively reducing the impact on the medical device holding structure when the medical device is transported or dropped. [Effects of the Invention]

[0030] According to the present disclosure, a medical device holding structure includes a mount that holds a medical device, and the multiple device holders provided on the mount include a first intermediate holder disposed between a first gripping portion and a second gripping portion of the medical device. As a result, by holding the space between the first gripping portion and the second gripping portion with the first intermediate holder of the device holder, it is possible to effectively prevent the medical device from coming off the mount during transportation or when dropped.

[0032] As shown in FIG. 1, a medical device package 10P according to this embodiment includes a medical device holding structure 10c, a packaging bag 10d that houses the medical device holding structure 10c, and a packaging box 10e that houses the packaging bag 10d.

[0033] The medical instrument holding structure 10c has a medical instrument 10a and a mount 10b that holds the medical instrument 10a.

[0034] As shown in FIG. 2, in this embodiment, the medical device 10a is a transfer device 11 for transferring a medical sheet 300 to a treatment target part of a living body. However, the medical device 10a is not limited to the transfer device 11. For example, the medical device 10a may be a treatment device for treating a treatment site of a living body. The transfer device 11 is used, for example, to treat severe heart failure caused by ischemic heart disease. In this case, the medical sheet 300 is transplanted into a heart transplant target part (a treatment target part of a living body) (see FIGS. 22 to 25). The transfer device 11 can attach multiple medical sheets 300 to the transplant target part.

[0035] Such medical sheets 300 include pharmaceuticals for medical use, regenerative medicine products, medical devices 10a, etc. The medical sheets 300 are formed in the form of a sheet, such as a film or membrane (gel-like substance). The medical sheets 300 may be reinforced by applying fibrin or the like. Regenerative medicine products containing cells include, for example, cell sheets (sheet-shaped cell cultures) and spheroids. Cell sheets can be formed by culturing autologous or allogeneic cells. Cells constituting the cell sheets include, for example, somatic stem cells (adult stem cells), mesenchymal stem cells, or cardiomyocytes derived from iPS cells (induced pluripotent stem cells). Somatic stem cells preferably include skeletal myoblasts (myoblast cells).

[0036] The medical sheet 300 may contain a tissue adhesive, a local anesthetic, etc. The thickness of the medical sheet 300 is, for example, about 100 μm, and the diameter of the medical sheet 300 is, for example, about 40 mm. However, the thickness and diameter (size) of the medical sheet 300 can be set as appropriate.

[0037] The medical sheet 300 may be a sheet to be transplanted into an organ other than the heart (for example, the lung, liver, pancreas, kidney, small intestine, esophagus, etc.) Furthermore, the medical sheet 300 may be a sheet for preventing adhesions, for example, if it is for medical use.

[0038] The transport instrument 11 includes an instrument body 12, an endoscope 14, and a fixing member 16. The instrument body 12 has an outer tube 17, a first carrier member 18, and a second carrier member 22. Note that the transport instrument 11 is not limited to being equipped with the endoscope 14.

[0039] The outer cylinder 17 is a cylindrical member having a lumen 171. The lumen 171 has a distal end opening 80 that opens at the distal end (end in the direction of arrow X1) of the outer cylinder 17. The lumen 171 opens at the proximal end (end in the direction of arrow X2) of the outer cylinder 17. A first shaft 181 of the first carrier member 18 is inserted into the lumen 171 of the outer cylinder 17. The outer cylinder 17 is flexible. The outer cylinder 17 is made of, for example, a resin material. Examples of materials that can be used for the outer cylinder 17 include, but are not limited to, polyethylene, polypropylene, fluororesin, polyethylene terephthalate, polymethyl methacrylate, polyamide resin, polystyrene, polycarbonate, polyimide, polyetherimide, polyether ether ketone, polyvinyl chloride, ABS resin, polyamide elastomer, and polyester elastomer. The outer cylinder 17 may also be made of a metal material.

[0040] As shown in FIG. 2, the proximal end of the outer tube 17 is provided with a first gripping portion 172. The first gripping portion 172 is formed in a cylindrical shape and is connected to the proximal end of the outer tube 17. The first shaft 181 and the second shaft 221 are inserted into the first gripping portion 172. The outer shape of the first gripping portion 172 is a cone shape that expands in diameter toward the proximal end. Note that the outer shape of the first gripping portion 172 is not limited to a cone shape. The proximal end of the first gripping portion 172 intersects with the axial direction of the outer tube 17. The first gripping portion 172 can be grasped by a user. The proximal end of the outer tube 17 is further provided with a first valve body (not shown). The first valve body maintains airtightness by being in close contact with the outer peripheral surface of the first shaft 181. As shown in FIG. 5, the distal end surface of the outer tube 17 extends in a direction perpendicular to the axial direction of the outer tube 17.

[0041] 3, the first carrier member 18 has a first shaft 181 and a first support portion 182. The first carrier member 18 is disposed inside the outer cylinder 17 so as to be movable along the axial direction of the outer cylinder 17. The first carrier member 18 has a first shaft 181 and a first expansion body 26.

[0042] The first shaft 181 is a tubular body (in this embodiment, a circular tubular member) having a first lumen 28. The first lumen 28 opens at the tip (end in the direction of arrow X1) of the first shaft 181 and at the base end (end in the direction of arrow X2) of the first shaft 181. The first shaft 181 extends in the axial direction of the outer tube 17 and is disposed inside the outer tube 17 so as to be movable along the axial direction. The tip of the first shaft 181 is provided with a notch 19. The notch 19 is cut out from the tip of the first shaft 181 toward the base end (direction of arrow X2). The notch 19 gradually tapers toward the base end. For example, the base end of the notch 19 is arc-shaped. The notch 19 is provided in the upper part of the first shaft 181.

[0043] The base end of the first shaft 181 is provided with a second grip portion 29. The second grip portion 29 is cylindrical and connected to the base end of the first shaft 181. The second grip portion 29 is disposed closer to the base end than the first grip portion 172 (see FIG. 2). The second shaft 221 is inserted through the second grip portion 29. The outer shape of the second grip portion 29 is a cone shape that widens in diameter toward the base end. Note that the outer shape of the second grip portion 29 is not limited to a cone shape. The base end of the second grip portion 29 intersects with the axial direction of the first shaft 181. The second grip portion 29 can be held by a user. As shown in FIG. 1, the outer diameter of the second grip portion 29 is smaller than the outer diameter of the first grip portion 172. That is, the outer diameter of the first grip portion 172 is larger than the outer diameter of the second grip portion 29. The outer diameter of first gripping portion 172 and the outer diameter of second gripping portion 29 may be the same. The outer diameter of first gripping portion 172 may be smaller than the outer diameter of second gripping portion 29. The base end of first shaft 181 is further provided with a second valve body (not shown). The second valve body maintains airtightness by coming into close contact with the outer circumferential surface of second shaft 221. The first shaft 181 is not limited to being a tubular body, and does not have to be a tubular body.

[0044] As shown in FIG. 2, the first shaft 181 extends in the axial direction of the outer tube 17 and is disposed inside the outer tube 17 so as to be movable along the axial direction. The first shaft 181 may be made of the same material as the aforementioned constituent material of the outer tube 17. The first shaft 181 may be flexible. The first shaft 181 may have a flexible tube portion that can maintain a bent shape. In this case, the first shaft 181 can be bent into an appropriate shape within a body cavity of a living organism and can maintain the bent shape.

[0045] As shown in FIG. 5, the first expansion body 26 is attached to the distal end of the first shaft 181. The first expansion body 26 is made of, for example, a resin material. In this embodiment, the first expansion body 26 is a sheet-like first support member 182 capable of holding a medical sheet 300. As shown in FIG. 4, the first expansion body 26 is formed by folding a flexible resin sheet material (film material) into a predetermined shape. The first expansion body 26 is formed, for example, by molding the sheet material into a predetermined shape using a sheet molding die. The thickness of the sheet material is not particularly limited, but is preferably set to, for example, 100 μm or more and 200 μm or less. The first expansion body 26 has a first joining portion 30 and a first support main body 32.

[0046] The constituent material of the first extension body 26 is not particularly limited, but is preferably transparent, and examples thereof include polyethylene, polycarbonate, polyamide, polystyrene, polypropylene, polyacetal resin, polyimide, polyetherimide, polyether ether ketone, polyethylene terephthalate, fluororesin, etc. The first extension body 26 may also be mesh-shaped.

[0047] 5, the first bonding portion 30 is bonded to the inner circumferential surface of the tip end of the first shaft 181 with an adhesive. The adhesive is not particularly limited, but examples thereof include UV adhesive, hot melt adhesive, and instant adhesive (e.g., cyanoacrylate instant adhesive). The first bonding portion 30 may be heat-sealed to the inner circumferential surface of the first shaft 181.

[0048] 4, the first support body 32 extends distally from the first joint portion 30. The first support body 32 has a base end support portion 34, an intermediate support portion 36, a pair of first protrusions 38, a pair of second protrusions 40, and a distal end support portion 42.

[0049] The base end support part 34 extends from the tip of the first joint part 30 toward the tip direction (the direction of arrow X1) so as to generally follow the axis Ax of the first shaft 181 (see FIG. 5). The base end support part 34 is formed to increase in width in the direction of extension. In other words, both side portions in the width direction of the base end support part 34 are tapered toward the first joint part 30.

[0050] The intermediate support part 36 extends from the distal end of the proximal support part 34 in the distal direction (arrow X1 direction) intersecting the axis Ax of the first shaft 181 and in the distal direction (arrow X1 direction) of the first expandable body 26 (see FIG. 5). The intermediate support part 36 is formed in a tapered shape whose width gradually decreases from the distal end toward the proximal end (arrow X2 direction).

[0051] 3 and 4, the pair of first protrusions 38 protrude upward (in the direction of arrow Y) and inward in the width direction of the intermediate support part 36 from both sides of the intermediate support part 36 in the width direction perpendicular to the movement direction of the first shaft 181. The first protrusions 38 are arc-shaped and bulge outward in a convex manner in a direction away from the first support surface 261.

[0052] 4, the pair of second protrusions 40 are respectively connected to the tips of the pair of first protrusions 38. The pair of second protrusions 40 protrude upward and outward in the width direction from both sides of the intermediate support part 36. The second protrusions 40 are formed with a smaller curvature than the first protrusions 38. The second protrusions 40 protrude lower from the first support surface 261 than the first protrusions 38.

[0053] The tip support portion 42 is connected to the tip of the intermediate support portion 36 and the tips of the pair of second protrusions 40. The tip support portion 42 protrudes in an arc shape toward the tip (direction of arrow X1). That is, when viewed from a direction perpendicular to the first support surface 261 shown in FIG. 6, the tip support portion 42 of the first extension body 26 has an arc shape connecting the pair of second protrusions 40.

[0054] Each of the pair of first protrusions 38 has a pair of bent portions 444. Each of the pair of bent portions 444 bends the pair of first protrusions 38 toward the first support surface 261 of the first support portion 182 (the intermediate support portion 36).

[0055] The first support body 32 has a front surface 461 that faces upward (in the direction of arrow Y) and includes the first support surface 261, and a back surface 462 that is the surface opposite the front surface 461. The first support surface 261 is a flat surface that is continuous with the upper surfaces of the base end support portion 34, the intermediate support portion 36, and the tip support portion 42. A lubricant may be applied to the first support surface 261 so that a second extension body 50 (described later) of the second carrier member 22 can slide smoothly on the first support surface 261.

[0056] As shown in Fig. 2, the second carrier member 22 is disposed inside the first shaft 181 so as to be movable along the axial direction of the first shaft 181. As shown in Fig. 3, the second carrier member 22 has a second shaft 221 and a second expansion body 50. The second expansion body 50 is a sheet-like second support part 222 capable of holding a medical sheet 300. The second carrier member 22 has a hub 52.

[0057] The second shaft 221 is a tubular body (a circular tubular member in this embodiment) having a second lumen 57. The length of the second shaft 221 along the axial direction is longer than the length of the first shaft 181 along the axial direction. The second shaft 221 extends along the first shaft 181 and is provided movably along the first shaft 181. The second shaft 221 is inserted through the first lumen 28 of the first shaft 181 (see FIG. 5). In other words, the distal end of the second shaft 221 protrudes in the distal direction (the direction of arrow X1) from the distal opening of the first shaft 181. The proximal end of the second shaft 221 protrudes in the proximal direction (the direction of arrow X2) from the proximal opening of the first shaft 181 (see FIG. 2). The second shaft 221 extends along the first shaft 181 and is provided movably along the first shaft 181. Note that the second shaft 221 is not limited to being a tubular body and may not be a tubular body.

[0058] The second shaft 221 is configured to be able to follow the shape of the first expansion body 26. As a constituent material of the second shaft 221, for example, a material that is more flexible than the constituent material of the first shaft 181 is selected. Specifically, examples of the constituent material of the second shaft 221 include polyamide elastomer, polyester elastomer, polyurethane elastomer, polyvinyl chloride, polybutadiene, silicone rubber, and metal coil (including composites with resin). The second shaft 221 is flexible.

[0059] 5, the second shaft 221 has a carrier holding portion 54 and a pressing portion 56 formed by the tip of the second shaft 221. The pressing portion 56 is formed from an elastic body such as an elastomer material. The pressing portion 56 presses the first expandable body 26 against the inner surface of the outer tube 17 when the first expandable body 26 is housed in the outer tube 17.

[0060] The tip of the carrier holding part 54 has a pressing surface 58. The carrier holding part 54 can press the outer peripheral edge surface of the medical sheet 300 supported by the first expandable body 26 in the tip direction (arrow X1 direction) using the pressing surface 58. In this embodiment, the pressing part 56 is provided with a carrier holding part 54 that supports the second expandable body 50. The carrier holding part 54 has a pressing surface 58 and an attachment hole 60.

[0061] As shown in FIG. 5, the pressing surface 58 is provided on the tip surface of the carrier holding part 54. An attachment hole 60 opens in the pressing surface 58. The second expandable body 50 is attached to the pressing surface 58. The pressing surface 58 presses the outer peripheral end surface of the medical sheet 300 in the tip direction (the direction of arrow X1) (see FIG. 24). The pressing surface 58 is a flat surface perpendicular to the axis of the carrier holding part 54.

[0062] The mounting hole 60 opens to the pressing surface 58 of the carrier holding portion 54. The mounting hole 60 is positioned on the center line of the carrier holding portion 54 on the pressing surface 58. The mounting hole 60 is slit-shaped and extends from the center line parallel to the width direction of the carrier holding portion 54. The mounting hole 60 is symmetrical in the width direction around the center line. The mounting hole 60 extends in the axial direction from the pressing surface 58. A portion of the second expansion body 50 is inserted into and connected to the mounting hole 60.

[0063] As shown in FIG. 4, the second extension body 50 is a flexible, sheet-like second support portion 222. The second extension body 50 has a second joint portion 70 and a second support main body 72. The second joint portion 70 is provided at the base end of the second extension body 50. The second joint portion 70 is provided at the base end of the second support main body 72. The second joint portion 70 is inserted into and adhered to the mounting hole 60 of the carrier holding portion 54. The second joint portion 70 may be adhered to the mounting hole 60 of the carrier holding portion 54 by an appropriate joining method other than adhesion. The second extension body 50 may also be molded integrally with the carrier holding portion 54.

[0064] The second support body 72 extends from the second joint 70 in the distal direction (the direction of arrow X1). The length of the second support body 72 in the direction extending from the second joint 70 is shorter than the length of the first support body 32 in the direction extending from the first joint 30. A second support surface 74 is provided on the upper surface of the second support body 72 for placing the medical sheet 300 thereon. The second support surface 74 is a flat surface. The second support body 72 is smaller than the first support body 32. In other words, the area of ​​the second support surface 74 is smaller than the area of ​​the first support surface 261.

[0065] The base end of the second support body 72 is formed to narrow in width toward the base end (arrow X2 direction). The intermediate portion between the tip and base end of the second support body 72 extends with a substantially constant width. The tip end of the second expandable body 50 protrudes in an arc shape toward the tip end (arrow X1 direction). A lubricant may be applied to both surfaces (lower and upper surfaces) of the second support body 72.

[0066] As shown in FIG. 3, the hub 52 is attached to the base end of the second shaft 221.

[0067] As shown in Fig. 3, the endoscope 14 has a long endoscope main body 86. The tip of the endoscope main body 86 is fixed to the outer peripheral surface of the outer tube 17 by a fixing member 16 (see Fig. 2). An objective lens 88 provided on the tip surface of the endoscope main body 86 faces the tip direction of the outer tube 17 (the direction of arrow X1). The tip of the endoscope main body 86 is fixed to a middle part of the outer tube 17 in the axial direction. However, the tip of the endoscope main body 86 may also be fixed to the tip of the outer tube 17.

[0068] The fixing member 16 includes, for example, a fixing barrel 90 and a fixing tube 92. The fixing barrel 90 is made of, for example, a hard resin material. The endoscope main body 86 can be inserted into the inner cavity of the fixing barrel 90. The fixing barrel 90 is arranged along the longitudinal direction of the outer barrel 17. The fixing tube 92 is a tube for fixing the fixing barrel 90 to a predetermined position on the outer barrel 17. The fixing tube 92 is, for example, a heat-shrinkable tube. Note that the outer barrel 17 and the fixing barrel 90 may be integrally molded. However, the method for fixing the tip end of the endoscope main body 86 to the outer barrel 17 can be set as appropriate.

[0069] The movement restricting unit 24 can restrict relative movement in the axial direction between the first shaft 181 and the second shaft 221. The movement restricting unit 24 is made up of a carrier holding unit 54 (pressing unit 56) formed by the tip end of the second shaft 221. With the first expandable body 26 housed in the outer tube 17, the carrier holding unit 54 presses the first expandable body 26 against the inner surface (lumen 171) of the outer tube 17, thereby restricting relative displacement between the first expandable body 26 and the second shaft 221. As the relative movement between the first expandable body 26 and the second shaft 221 is restricted, the relative movement between the first shaft 181 and the second shaft 221 in the axial direction is restricted.

[0070] The first expandable body 26 and the second expandable body 50 are not limited to being in the form of a flexible sheet capable of holding the medical sheet 300. The first expandable body 26 and the second expandable body 50 may be configured to be deployable (expandable) by protruding (exposed) in the distal direction from the distal opening 80 of the outer tube 17. When the medical device 10a is not the delivery instrument 11, other embodiments of the first expandable body 26 and the second expandable body 50 include, for example, a stent, a mesh structure made of a metal material or a resin material, and the like.

[0071] As shown in Fig. 7, mount 10b of medical device holding structure 10c is formed, for example, from thick paper having a thickness T (Fig. 10A) and is formed into a rectangular shape in a plan view. Hereinafter, the long side direction of mount 10b will be referred to as the longitudinal direction (direction of arrow A). The short side direction of mount 10b, which is perpendicular to the longitudinal direction, will be referred to as the width direction (direction of arrow B).

[0072] 1, the mount 10b includes a mount body 100 and a cover portion 102 provided at the leading end of the mount body 100 and continuing to the mount body 100. The mount 10b has a plurality of device holding portions 104. The plurality of device holding portions 104 can hold medical devices 10a.

[0073] The mount body 100 extends in the longitudinal direction of the mount 10b (the direction of arrow A). The top surface of the mount body 100 has a holding surface 100a capable of holding the medical device 10a.

[0074] The multiple device holding sections 104 include a base end holding section 106 , a tip end holding section 108 , a first intermediate holding section 1101 , a second intermediate holding section 1102 , and multiple hooks 112 .

[0075] The proximal end holding portion 106 is capable of holding the hub 52 of the medical device 10a. The proximal end holding portion 106 is provided at the proximal end in the longitudinal direction of the mount body 100. The proximal end holding portion 106 includes a proximal end support piece 114. The proximal end support piece 114 is formed in a substantially rectangular shape and is formed by cutting out a portion of the mount body 100. With respect to the flat mount body 100 shown in FIG. 7, the proximal end support piece 114 is cut out and raised from the mount body 100 so as to be substantially perpendicular to the holding surface 100a of the mount body 100 (see FIG. 8). In this case, the lower end of the proximal end support piece 114 is a fixed end fixed to the mount body 100, and the upper end of the proximal end support piece 114 is a free end separated from the mount body 100. As shown in FIG. 8, the proximal end support piece 114 protrudes upward from the holding surface 100a of the mount body 100. In other words, the base end support piece 114 stands upright by being bent relative to the mount body 100 .

[0076] As shown in FIG. 9A , the base-end support piece 114 has a base-end support hole 116 into which the hub 52 of the medical device 10a is inserted and held. The base-end support hole 116 penetrates the base-end support piece 114 in the thickness direction (the longitudinal direction of the mount body 100). As shown in FIG. 10A , the base-end support hole 116 has a generally circular cross section into which the hub 52 can be inserted. The diameter of the base-end support hole 116 corresponds to the diameter of the hub 52. The base-end support hole 116 opens at the top of the base-end support piece 114 via a base-end insertion port 186. By inserting the hub 52 of the medical device 10a into the base-end support hole 116 via the base-end insertion port 186, the outer peripheral surface of the hub 52 is held by the base-end support piece 114. At this time, the holding surface 100a of the mount body 100 and the hub 52 are spaced apart.

[0077] As shown in FIG. 1, the tip holding portion 108 is capable of holding the tip portion of the first shaft 181 of the medical device 10a. The tip holding portion 108 is provided at the tip portion in the longitudinal direction of the mount body 100. The tip holding portion 108 includes a tip support piece 120. The tip support piece 120 is formed in a substantially rectangular shape and is formed by cutting out a portion of the mount body 100. With respect to the flat mount body 100 shown in FIG. 7, the tip support piece 120 is cut and raised so as to be substantially perpendicular to the holding surface 100a of the mount body 100 (see FIG. 8). In this case, the lower end of the tip support piece 120 is a fixed end fixed to the mount body 100, and the upper end of the tip support piece 120 is a free end separated from the mount body 100. As shown in FIG. 8, the tip support piece 120 protrudes upward from the holding surface 100a of the mount body 100. In other words, the tip support piece 120 stands upright by being bent relative to the mount body 100. In the mount body 100, the base end support piece 114 and the tip support piece 120 face each other in the longitudinal direction (see FIG. 1). The base end support piece 114 and the tip support piece 120 are spaced apart in the longitudinal direction of the mount body 100 and are parallel to each other.

[0078] As shown in FIG. 9B, the tip support piece 120 has a tip side support hole 122 into which the first shaft 181 is inserted and held. The tip side support hole 122 penetrates the tip support piece 120 in the thickness direction (the longitudinal direction of the mount main body 100). As shown in FIG. 10B, the tip side support hole 122 has a substantially circular cross section into which the first shaft 181 can be inserted. The diameter of the tip side support hole 122 corresponds to the diameter of the first shaft 181. The tip side support hole 122 opens at the top of the tip support piece 120 through a tip insertion opening 190. By inserting the first shaft 181 of the medical device 10a into the tip side support hole 122 through the tip insertion opening 190, the outer circumferential surface of the first shaft 181 is held by the tip support piece 120. At this time, the holding surface 100a of the mount main body 100 and the first shaft 181 are spaced apart.

[0079] 9B, the tip support piece 120 has a pair of engagement ends 1281, 1282 arranged on both sides of the tip insertion opening 190 and the tip side support hole 122. The engagement ends 1281, 1282 face each other with the tip insertion opening 190 and the tip side support hole 122 between them.

[0080] As shown in Figures 9A and 9B, when the medical device 10a is held in the base end support hole 116 of the base end support piece 114 and the tip end support hole 122 of the tip end support piece 120, the medical device 10a and the backing board main body 100 are approximately parallel (see Figure 8).

[0081] 1, the first intermediate holding portion 1101 and the second intermediate holding portion 1102 can hold an intermediate portion of the medical device 10a in the axial direction. The first intermediate holding portion 1101 and the second intermediate holding portion 1102 are provided on the mount body 100 between the base end holding portion 106 and the tip end holding portion 108. The first intermediate holding portion 1101 is disposed between the first gripping portion 172 of the outer tube 17 and the second gripping portion 29 of the first shaft 181. Note that the configuration is not limited to including the first intermediate holding portion 1101 and the second intermediate holding portion 1102. For example, a configuration including only the first intermediate holding portion 1101 may be used.

[0082] As shown in FIG. 8, the first intermediate holding portion 1101 includes a first intermediate support piece 1301 erected on the holding surface 100a of the mount main body 100. The first intermediate support piece 1301 is formed in a substantially rectangular shape by cutting out a portion of the mount main body 100. Compared to the flat mount main body 100 shown in FIG. 7, the first intermediate support piece 1301 is cut and raised so as to protrude from the holding surface 100a of the mount main body 100. As shown in FIG. 11, the first intermediate support piece 1301 is cut and raised from the mount main body 100 toward the base end. As shown in FIG. 12A, the lower end of the first intermediate support piece 1301 is a fixed end fixed to the mount main body 100, and the upper end of the first intermediate support piece 1301 is a free end spaced apart from the mount main body 100. The first intermediate support piece 1301 protrudes upward from the holding surface 100a of the mount main body 100. That is, the first intermediate support piece 1301 stands upright by being bent relative to the mount body 100. Note that the first intermediate support piece 1301 is not limited to a configuration formed by cutting and raising it from the mount body 100. For example, the first intermediate support piece 1301 may be a protrusion that protrudes from the holding surface 100a of the mount body 100.

[0083] The first intermediate support piece 1301 is capable of contacting the base end of the first gripping portion 172 and the tip end of the second gripping portion 29. FIG. 11 shows a state in which the base end of the first gripping portion 172 is spaced away from the first intermediate support piece 1301 in the tip direction. The tip end of the second gripping portion 29 is also shown spaced away from the first intermediate support piece 1301 in the base direction. For example, the base end of the first gripping portion 172 may be held in contact with the first intermediate support piece 1301. The tip end of the second gripping portion 29 may be held in contact with the first intermediate support piece 1301. The first intermediate support piece 1301 has a first intermediate support hole 1321 that supports the first shaft 181. The first shaft 181 is inserted into the first intermediate support hole 1321. The first intermediate support hole 1321 penetrates the first intermediate support piece 1301 in the thickness direction (longitudinal direction of the mount main body 100). The first intermediate support hole 1321 has a substantially circular cross section into which the first shaft 181 can be inserted. The diameter of the first intermediate support hole 1321 is substantially the same as the diameter of the first shaft 181. The diameter of the first intermediate support hole 1321 is smaller than the outer diameter of the base end of the first gripping portion 172. Therefore, the base end of the first gripping portion 172 can be locked by the first intermediate support piece 1301. The diameter of the first intermediate support hole 1321 is smaller than the outer diameter of the tip end of the second gripping portion 29. Therefore, the tip end of the second gripping portion 29 can be locked by the first intermediate support piece 1301. The first intermediate support hole 1321 opens to the top of the first intermediate support piece 1301 via a first insertion opening 1921. The opening width of the first insertion opening 1921 is smaller than the diameter of the first intermediate support hole 1321. The opening width of the first insertion opening 1921 is a dimension along the width direction (direction of arrow B) of the mount 10b. By inserting the first shaft 181 of the medical device 10a into the first intermediate support hole 1321 through the first insertion opening 1921, the outer peripheral surface of the first shaft 181 is held by the first intermediate support piece 1301. Because the opening width of the first insertion opening 1921 is smaller than the diameter of the first shaft 181, removal of the first shaft 181 from the first intermediate support hole 1321 through the first insertion opening 1921 is suppressed. The holding surface 100a of the mount main body 100 and the first shaft 181 are separated. The first gripping portion 172 and the holding surface 100a of the mount main body 100 are separated.

[0084] As shown in FIG. 1, the second intermediate holding portion 1102 is disposed closer to the base end of the mount body 100 than the first intermediate holding portion 1101. The second intermediate holding portion 1102 is disposed closer to the base end of the second gripping portion 29. The second intermediate holding portion 1102 includes a second intermediate support piece 1302 erected on the holding surface 100a of the mount body 100. The second intermediate support piece 1302 is formed in a substantially rectangular shape by cutting out a portion of the mount body 100. Compared to the flat mount body 100 shown in FIG. 7, the second intermediate support piece 1302 is cut and raised so as to protrude from the holding surface 100a of the mount body 100. As shown in FIG. 11, the second intermediate support piece 1302 is cut and raised from the mount body 100 toward the tip. As shown in FIG. 12B, the second intermediate support piece 1302 is cut and raised from the mount body 100 in a direction approaching the first intermediate support piece 1301. That is, the first intermediate support piece 1301 and the second intermediate support piece 1302 are cut and raised from different directions. The first intermediate support piece 1301 and the second intermediate support piece 1302 may be cut and raised from the same direction. When the first intermediate support piece 1301 and the second intermediate support piece 1302 are cut and raised from the same direction, it is preferable to cut and raise the first intermediate support piece 1301 and the second intermediate support piece 1302 toward the tip end. The second intermediate support piece 1302 is not limited to a configuration formed by cutting and raising it from the mount body 100. For example, the second intermediate support piece 1302 may be a protrusion that protrudes from the holding surface 100a of the mount body 100.

[0085] The lower end of the second intermediate support piece 1302 is a fixed end fixed to the mount body 100, and the upper end of the second intermediate support piece 1302 is a free end separated from the mount body 100. The second intermediate support piece 1302 protrudes upward from the holding surface 100a of the mount body 100. In other words, the second intermediate support piece 1302 stands upright by being bent relative to the mount body 100.

[0086] The second intermediate support piece 1302 can come into contact with the base end of the second gripping portion 29. FIG. 11 shows a state in which the base end of the second gripping portion 29 is separated from the second intermediate support piece 1302 in the base end direction. For example, the base end of the second gripping portion 29 may be held in contact with the second intermediate support piece 1302. The second intermediate support piece 1302 has a second intermediate support hole 1322 that supports the second shaft 221. The second shaft 221 is inserted into the second intermediate support hole 1322. The second intermediate support hole 1322 penetrates the second intermediate support piece 1302 in the thickness direction (the longitudinal direction of the mount main body 100). The second intermediate support hole 1322 has a substantially circular cross section into which the second shaft 221 can be inserted. The diameter of the second intermediate support hole 1322 is substantially the same as the diameter of the second shaft 221. The diameter of the second intermediate support hole 1322 is smaller than the outer diameter of the base end of the second gripping portion 29. Therefore, the base end of the second gripping portion 29 is held in the base end direction by the second intermediate support piece 1302. The diameter of the second intermediate support hole 1322 is smaller than the diameter of the first intermediate support hole 1321 (see FIG. 12A). In other words, the diameter of the first intermediate support hole 1321 is larger than the diameter of the second intermediate support hole 1322.

[0087] The second intermediate support hole 1322 opens to the top of the second intermediate support piece 1302 via the second insertion opening 1922. The opening width of the second insertion opening 1922 is smaller than the diameter of the second intermediate support hole 1322. The opening width of the second insertion opening 1922 is a dimension along the width direction of the mount 10b (the direction of arrow B). By inserting the second shaft 221 of the medical device 10a into the second intermediate support hole 1322 via the second insertion opening 1922, the outer circumferential surface of the second shaft 221 is held by the second intermediate support piece 1302. Because the opening width of the second insertion opening 1922 is smaller than the diameter of the second shaft 221, removal of the second shaft 221 from the second intermediate support hole 1322 via the second insertion opening 1922 is suppressed. At this time, the holding surface 100a of the mount main body 100 and the second shaft 221 are separated from each other. The second gripping portion 29 and the holding surface 100a of the mount body 100 are separated from each other.

[0088] A second distance H2 from the holding surface 100a of the mount body 100 to the bottom of the second intermediate support hole 1322 is greater than a first distance H1 from the holding surface 100a to the bottom of the first intermediate support hole 1321 shown in Fig. 12A (H2>H1). Note that the second distance H2 and the first distance H1 may be the same.

[0089] The first intermediate support piece 1301 and the second intermediate support piece 1302 face each other in the longitudinal direction of the mount 10b (see FIG. 1). The first intermediate support piece 1301 and the second intermediate support piece 1302 are spaced apart in the longitudinal direction of the mount body 100 and are parallel to each other (see FIG. 8).

[0090] 1 is held by the device holding portion 104 of the mount 10b, the first gripping portion 172 and the second gripping portion 29 are disposed close to each other in the longitudinal direction of the mount 10b (the direction of arrow A) as shown in FIG. 11. When the distance between the end face of the base end of the first gripping portion 172 and the end face of the tip end of the second gripping portion 29 in the axial direction of the medical device 10a is defined as a separation distance K, the separation distance K between the first gripping portion 172 and the second gripping portion 29 is equal to or greater than the thickness T (see FIG. 10A ) of the mount 10b (first intermediate support piece 1301, second intermediate support piece 1302). For example, the separation distance K is preferably equal to or greater than 1 mm. The second gripping portion 29 is disposed between the first intermediate holding portion 1101 and the second intermediate holding portion 1102. Note that the separation distance K is not limited to being equal to or greater than the thickness T of the mount 10b. For example, the separation distance K may be approximately the same as the thickness T of the mount 10b. That is, the base end surface of the first gripping portion 172 may be in contact with one surface of the first intermediate support piece 1301, and the tip surface of the second gripping portion 29 may be in contact with the other surface of the first intermediate support piece 1301. In the longitudinal direction of the mount 10b, the separation distance K1 between the first intermediate support piece 1301 and the second intermediate support piece 1302 is preferably equal to or greater than the length K2 of the second gripping portion 29 in the axial direction of the first shaft 181 (K1≧K2).

[0091] As shown in FIG. 1 , the plurality of hooks 112 are disposed on the mount body 100 between the tip holding portion 108 and the first intermediate holding portion 1101. The plurality of hooks 112 protrude from the mount body 100 to hold the outer tube 17. The plurality of hooks 112 are formed by cutting and raising them from the flat mount body 100 shown in FIG. 7 . The plurality of hooks 112 are disposed so as to be staggered in the width direction with respect to the center line E of the device holding portion 104, which connects the center of the first support hole 184 of the base end support piece 114 and the center of the tip side support hole 122 of the tip support piece 120. Below, a case where the device holding portion 104 includes three hooks 112 will be described. Note that the number of hooks 112 is not limited to three. For example, the number of hooks 112 may be two or less, or four or more.

[0092] Each of the multiple hooks 112 has a fixed end 1341 supported by the mount body 100 and a free end 1342 provided on the opposite side to the fixed end 1341. The fixed ends 1341 and free ends 1342 of each hook 112 are arranged alternately in the longitudinal direction of the mount body 100. The multiple hooks 112 are arranged spaced apart from one another in the longitudinal direction of the mount body 100. The fixed end 1341 of each hook 112 has a perforation, and the hook 112 is fixed to the mount body 100 via the perforation. The perforation makes it easy to cut and raise the hook 112 from the mount body 100.

[0093] As shown in Fig. 8, when the medical device 10a is held on the mount body 100, each hook 112 is positioned upward from the mount body 100 and covers the outer tube 17 of the medical device 10a between the fixed end 1341 and the free end 1342. Each hook 112 contacts the outer peripheral surface of the outer tube 17. As shown in Fig. 1, when viewed from a direction perpendicular to the holding surface 100a of the mount 10b, the outer tube 17 is located between the fixed end 1341 and the free end 1342 of the hook 112. The medical device 10a including the outer tube 17 is held between the multiple hooks 112 and the holding surface 100a of the mount body 100.

[0094] The mount body 100 further includes a stepped portion 136 .

[0095] The stepped portion 136 is arranged on the tip side of the mount main body 100. The stepped portion 136 is arranged at the boundary between the mount main body 100 and the cover portion 102. The stepped portion 136 is bent downward relative to the tip of the mount main body 100. The stepped portion 136 extends downward from the tip of the mount main body 100. The upper end of the stepped portion 136 is connected to the tip of the mount main body 100. The tip support piece 120 is arranged at the upper end of the stepped portion 136. In other words, the stepped portion 136 and the tip support piece 120 are arranged at the same position in the longitudinal direction of the mount 10b.

[0096] When the medical device package 10P is placed on a flat surface, the lower end of the stepped portion 136 becomes the base portion 194 against the surface. The medical device package 10P is placed stably when the base portion 194, which is the lower end of the stepped portion 136, and the base end of the mount body 100 come into contact with the flat surface. At this time, the medical device package 10P is slightly inclined upward from the base end to the tip. Note that this is not limited to providing the stepped portion 136. The mount body 100 and the cover portion 102 may be formed on the same plane along the longitudinal direction.

[0097] The cover portion 102 is disposed toward the tip of the mount body 100. The cover portion 102 is connected to the lower end (base portion 194) of the stepped portion 136. When the medical device 10a is held on the mount 10b, the cover portion 102 has a bent shape that is folded back so as to cover the first expansion body 26 and the second expansion body 50 of the medical device 10a.

[0098] The cover portion 102 has a cover main body 196 and an engaging portion 198 that engages with the medical device 10a. The cover main body 196 is connected to the lower end of the stepped portion 136. The cover main body 196 extends in a direction away from the mount main body 100 (to the right in FIG. 8 ) and then bends upward and is folded back toward the base end side of the mount main body 100 (to the left in FIG. 8 ). The cover main body 196 has a bottom portion 1961 that extends flat from the stepped portion 136, a curved portion 1962 that has an arc-shaped cross section and is curved upward and folded back from the end of the bottom portion 1961 opposite the stepped portion 136, and a ceiling portion 1963 that extends from the upper end of the curved portion 1962 toward the tip support piece 120. The bottom portion 1961 and the ceiling portion 1963 are spaced apart in the vertical direction and are generally parallel to each other. 8, cover main body 196 has a generally U-shape folded back at curved portion 1962. Ceiling portion 1963 may have a viewing opening. In this case, the user can view the inside of cover portion 102 from outside ceiling portion 1963 through the opening.

[0099] As shown in FIG. 8, the engagement portion 198 is bent downward relative to the ceiling portion 1963 and extends downward.

[0100] As shown in FIG. 10B , the lower end of the engaging portion 198 has an engaging hole 1981 that can engage with the first shaft 181 of the medical device 10a. The engaging hole 1981 penetrates the engaging portion 198 in the thickness direction (the longitudinal direction of the mount body 100). The engaging hole 1981 has a substantially circular cross section into which the first shaft 181 can be inserted. The diameter of the engaging hole 1981 corresponds to the diameter of the first shaft 181. The engaging hole 1981 has substantially the same shape as the tip side support hole 122 of the tip support piece 120. The engaging hole 1981 opens at the bottom of the engaging portion 198 via an engaging opening 1982 (see FIG. 7 ). By inserting the first shaft 181 of the medical device 10a into the engaging hole 1981 via the engaging opening 1982, the outer circumferential surface of the first shaft 181 and the engaging portion 198 are engaged.

[0101] 9B, the tip support piece 120 and the engaging portion 198 are engaged so as to intersect with each other via the engaging hole 1981 and the tip side support hole 122. In detail, the engaging end 1281 of the tip support piece 120 is arranged on the accommodation portion 204 side with respect to the engaging portion 198, and the engaging end 1282 is arranged on the base end side with respect to the engaging portion 198. In other words, the tip support piece 120 is slightly inclined with respect to the engaging portion 198 extending in the width direction.

[0102] 8, the medical device 10a is held by the base end support piece 114 and the distal end support piece 120, and the engaging hole 1981 of the engaging portion 198 is engaged with the first shaft 181, thereby holding the engaging portion 198 by the first shaft 181. With the engaging portion 198 held by the first shaft 181, the distal end (first expansion body 26 and second expansion body 50) of the medical device 10a is covered by the cover part 102. That is, the first shaft 181 of the medical device 10a is supported by the distal end support piece 120, and the engaging portion 198 of the cover part 102 is held by the first shaft 181. As a result, a storage section 204 surrounded by the cover body 196 and the engaging portion 198 is formed inside the cover part 102. The distal end of the medical device 10a can be housed in the storage section 204. The storage section 204 is open on both widthwise sides of the cover part 102. It should be noted that the mount 10b is not limited to a configuration including the cover portion 102. For example, the mount 10b does not have to include the cover portion 102.

[0103] As shown in FIG. 9B , the bottom 1961 of the cover main body 196 includes a cover separation portion 202. The cover separation portion 202 can separate the cover portion 102 from the mount main body 100 and is disposed, for example, spaced apart from the stepped portion 136. The cover separation portion 202 extends linearly along the width direction (direction of arrow B) of the mount 10b. The cover separation portion 202 is a break line 2021 that can separate the bottom 1961 of the cover portion 102 in the longitudinal direction of the mount 10b. The break line 2021 is a perforation with multiple notches cut in the thickness direction of the mount main body 100. When removing the medical device 10a from the mount 10b, the break line 2021 can be broken with the engaging portion 198 disengaged from the first shaft 181 and the cover portion 102 unfolded.

[0104] Next, a case where the medical device 10a is held on the mount 10b to form the medical device holding structure 10c will be described.

[0105] 7 is prepared, and the base end support piece 114, the tip end support piece 120, the first intermediate support piece 1301, and the second intermediate support piece 1302 are raised upright from the base body 100, and the stepped portion 136 is bent relative to the base body 100. As a result, the base end support piece 114, the tip end support piece 120, the first intermediate support piece 1301, and the second intermediate support piece 1302 are formed relative to the holding surface 100a of the base body 100, and the stepped portion 136 is formed between the base body 100 and the cover portion 102.

[0106] The base end support piece 114, the tip end support piece 120, the first intermediate support piece 1301, and the second intermediate support piece 1302 are each perpendicular to the holding surface 100a of the mount 10b.

[0107] As shown in FIG. 1, the medical device 10a is in an expanded state in which the first expandable body 26 and the second expandable body 50 protrude outward from the distal opening 80 of the outer tube 17, and the outer tube 17 and the first shaft 181 are moved relative to each other to bring the first gripping portion 172 and the second gripping portion 29 into a position close to each other. The hub 52 of the medical device 10a is inserted into the proximal support hole 116 of the proximal support piece 114 through the proximal insertion opening 186 (see FIG. 10A). The distal end of the first shaft 181 is inserted into the distal support hole 122 of the distal support piece 120 through the distal insertion opening 190 (see FIG. 10B). As a result, the proximal end and distal end of the medical device 10a are held by the proximal holding portion 106 and the distal holding portion 108, respectively.

[0108] Furthermore, in the medical device 10a, the first shaft 181 is inserted into the first intermediate support hole 1321 of the first intermediate support piece 1301 at the base end side of the first gripping portion 172. The second shaft 221 is inserted into the second intermediate support hole 1322 of the second intermediate support piece 1302 at the base end side of the second gripping portion 29. As shown in FIG. 11 , the second gripping portion 29 is disposed between the first intermediate holding portion 1101 and the second intermediate holding portion 1102. The first intermediate support piece 1301 and the second intermediate support piece 1302 are spaced apart from the second gripping portion 29 in the axial direction of the outer tube 17. Note that the second gripping portion 29 is not limited to being spaced apart from the first intermediate support piece 1301 and the second intermediate support piece 1302. For example, the second gripping portion 29 may be in contact with the first intermediate support piece 1301 and the second intermediate support piece 1302, or the second gripping portion 29 may be in contact with either the first intermediate support piece 1301 or the second intermediate support piece 1302. The second gripping portion 29 in the medical device 10a is positioned by the first intermediate support piece 1301 and the second intermediate support piece 1302. The relative positions of the outer tube 17 having the first gripping portion 172 and the first shaft 181 having the second gripping portion 29 are determined. At this time, the first intermediate holding portion 1101 is disposed between the first gripping portion 172 and the second gripping portion 29.

[0109] 13, the outer tube 17, the first shaft 181, and the second shaft 221 face the holding surface 100a of the mount body 100 and are held substantially parallel to and spaced apart from the holding surface 100a. At this time, the first intermediate holding portion 1101 and the second intermediate holding portion 1102 maintain the central axes of the first shaft 181 and the second shaft 221 substantially horizontally. The medical device 10a is held substantially parallel to the holding surface 100a of the mount 10b. The first gripping portion 172 and the second gripping portion 29 are held apart from the holding surface 100a of the mount 10b and are not in contact with each other. The first gripping portion 172 may be in contact with the holding surface 100a of the mount 10b.

[0110] By raising the multiple hooks 112 upward from the mount body 100 and inserting the outer tube 17 between the free end 1342 and the fixed end 1341 of each hook 112, the outer circumferential surface of the outer tube 17 is pressed toward the mount body 100 by each hook 112. The outer tube 17 is held between the multiple hooks 112 and the holding surface 100a of the mount 10b. The first expansion body 26 and the second expansion body 50 face the bottom 1961 of the cover part 102 and are disposed above the bottom 1961.

[0111] In the cover unit 102, the engaging portion 198 is bent at a predetermined position relative to the cover body 196, and then the cover body 196 is bent so as to fold back toward the outer tube 17. As a result, as shown in FIG. 8, the cover body 196 of the cover unit 102 is curved into a substantially U-shape that opens toward the outer tube 17. The engaging hole 1981 of the engaging portion 198 is moved from above the tip support piece 120 toward the first shaft 181. The engaging hole 1981 is inserted into the first shaft 181 from above the first shaft 181 through the engaging opening 1982. The engaging portion 198 is held by the first shaft 181. The engaging portion 198 is arranged along a vertical direction perpendicular to the axis of the first shaft 181. As a result, as shown in FIG. 14, the first expansion body 26 and the second expansion body 50 are covered by the bottom portion 1961, the curved portion 1962, and the ceiling portion 1963 of the cover body 196 and the engaging portion 198.

[0112] In detail, the first expansion body 26 and the second expansion body 50 are covered in the longitudinal direction and the vertical direction of the base 10b by the cover part 102 and are accommodated in the accommodation part 204. At this time, since the accommodation part 204 has a predetermined volume in the longitudinal direction and the vertical direction of the base 10b, the first expansion body 26 and the second expansion body 50 are arranged apart from the cover part 102 and do not come into contact with each other.

[0113] As shown in FIG. 1, a medical device holding structure 10c, in which a medical device 10a is held on a mount 10b, is contained in a packaging bag 10d and a packaging box 10e. As shown in FIG. 8, the packaging bag 10d is, for example, a transparent, sealable bag. The medical device holding structure 10c is sealed inside the packaging bag 10d. The packaging bag 10d includes a storage section 250 in which the medical device holding structure 10c is stored, a first bag end 252 provided at one end of the storage section 250, a second bag end 254 which is a closed end provided at the other end of the storage section 250, and a pair of side edges 255 connecting the first bag end 252 and the second bag end 254. The side edges 255 extend along the longitudinal direction of the packaging bag 10d. When the medical device 10a is not stored inside the packaging bag 10d, the thickness of the first bag end 252 and the second bag end 254 are approximately the same. The first bag end 252 is an end that is opened before the medical device holding structure 10c is accommodated in the accommodating portion 250. The first bag end 252 is sealed when the medical device holding structure 10c is accommodated in the accommodating portion 250. By sealing the first bag end 252, the accommodating portion 250 containing the medical device 10a is hermetically sealed. When the medical device 10a is removed from the accommodating portion 250, the first bag end 252 is opened. The second bag end 254 has a pair of corners 2561, 2562 formed at the intersections with the pair of side edges 255. The pair of corners 2561, 2562 are provided at both ends in the width direction perpendicular to the longitudinal direction of the packaging bag 10d.

[0114] When the medical device holding structure 10c is accommodated in the accommodation portion 250 of the packaging bag 10d, the cover portion 102 covering the first expandable body 26 and the second expandable body 50 is accommodated in the second bag end 254. The base end of the medical device 10a is accommodated in the first bag end 252. As the cover portion 102 is accommodated in the second bag end 254, the cover portion 102 expands the second bag end 254 in the thickness direction, starting from a pair of side edges 255. As the second bag end 254 expands in the thickness direction, the second bag end 254 becomes thicker than the first bag end 252. In other words, with the medical device holding structure 10c accommodated in the accommodation portion 250, the thickness t2 of the second bag end 254 that accommodates the cover portion 102 is greater than the thickness t1 of the first bag end 252 (t2>t1) in the thickness direction of the packaging bag 10d, which is perpendicular to the extension direction of the packaging bag 10d. When the medical device holding structure 10c is contained in the packaging bag 10d, the second bag end 254 becomes larger in the thickness direction, causing the pair of corners 2561, 2562 to expand in the thickness direction of the packaging bag 10d and form a triangular shape tapering toward the tip of the packaging bag 10d.

[0115] The packaging bag 10d containing the medical device holding structure 10c is contained in a packaging box 10e. The packaging bag 10d is contained from the second bag end 254 toward the packaging box 10e. At this time, as shown in FIG. 15, the packaging bag 10d is contained in the packaging box 10e in a state in which a pair of corners 2561, 2562 of the packaging bag 10d are folded in directions that bring them closer to each other. With the packaging bag 10d contained in the packaging box 10e, the folded pair of corners 2561, 2562 come into contact with the longitudinal end 260 of the packaging box 10e (see FIG. 1). When the pair of corners 2561, 2562 are folded, the corners 2561, 2562 are contained so that they taper in directions that bring them closer to each other (see FIG. 15).

[0116] Next, when removing the medical device 10a from the mount 10b, the first bag end 252 of the packaging bag 10d is opened and the medical device holding structure 10c is removed from the packaging bag 10d, and then, as shown in Fig. 16, the engaging portion 198 of the cover part 102 is moved upward so as to move away from the medical device 10a. The engagement of the engaging hole 1981 with the first shaft 181 is released. By further opening the cover part 102, the proximal end and upper parts of the storage part 204 are opened, and the cover part 102 is placed in an unfolded state (see Fig. 16).

[0117] When the cover part 102 is deployed in a direction away from the first expansion body 26 and the second expansion body 50, the tip support piece 120 tilts toward the holding surface 100a of the mount main body 100, with the fixed end of the tip support piece 120 as a fulcrum (see the two-dot chain line in FIG. 16). The user grasps the medical device 10a and moves it upward relative to the mount 10b so as to move it away from the mount 10b. The mount 10b releases the hold of the medical device 10a, and the medical device 10a is removed from the mount 10b.

[0118] At this time, the user can remove the unfolded cover part 102 from the mount 10b by separating the cover part 102 in the distal direction using the cover separating part 202. This prevents the unfolded cover part 102 from interfering with the removal of the medical device 10a.

[0119] Next, a test conducted to confirm detachment of the medical device 10a from the mount 10b when the medical device holding structure 10c is transported and dropped will be described. The test was conducted using a comparative example and examples A to C. Example C corresponds to the medical device package 10P according to the present embodiment described above. Below, for the comparative example and examples A to C, the test was conducted by dropping a rectangular parallelepiped packaging box containing the medical device holding structure, with the medical device holding structure housed in the packaging bag. The test method was the same for the comparative example and examples A and B, in which the packaging box containing the medical device holding structure was allowed to freely drop from a height of 800 mm on each of the six sides of the packaging box. That is, the drop test was conducted by free-falling the packaging box containing the medical device holding structure six times from a height of 800 mm.

[0120] [Comparative Example] (Test specimen) A mount that does not have a first intermediate support piece and a second intermediate support piece is used, and a medical device holding structure is used in which the medical device is held by the base end holding portion, the tip end holding portion, and the hook on the mount.

[0121] [result] No damage to the medical device or mount, but the medical device came off the mount (N number: 1 time).

[0122] [Example A] (Test specimen) The base has the first intermediate support piece, but does not have the second intermediate support piece (cutting direction: toward the tip).

[0123] [result] (A1) When the distance between the first gripping portion and the second gripping portion across the first intermediate support piece is large, the medical device detaches from the mount (N number: 1 time). (A2) When the distance between the first gripping portion and the second gripping portion with the first intermediate support piece therebetween is small, the medical device does not come off the mount (N number: 1 time).

[0124] [Example B] (Test specimen) The base has a first intermediate support piece and a second intermediate support piece (cutting direction: both the first intermediate support piece and the second intermediate support piece are toward the tip).

[0125] [result] No medical devices came off the mount (N number: 1 time).

[0126] [Example C] (present embodiment) (Test specimen) The base has a first intermediate support piece and a second intermediate support piece (cutting direction: the first intermediate support piece is toward the base end, and the second intermediate support piece is toward the tip end). (Test Method) (C1) A drop test was conducted in which the medical device holding structure was allowed to freely drop six times from a height of 800 mm (similar to the comparative example, Examples A and B). (C2) A drop test and vibration test (random vibration test) were conducted in accordance with JIS Z0200:2023. The test conditions for the drop test and vibration test were set to level 3. For the drop test, a rectangular parallelepiped packaging box containing a medical device holding structure was allowed to fall freely from a height of 600 mm, in the order of one corner, three sides, and six faces.

[0127] [result] (C1) The medical device 10a did not come off the backing 10b, the backing 10b was not damaged, the medical device 10a was not damaged, and the packaging bag 10d was not damaged (N number: 1 time). (C2) The medical device 10a did not come off the backing 10b, the backing 10b was not damaged, the medical device 10a was not damaged, and the packaging bag 10d was not damaged (N number: 3 times).

[0128] As a result of the above test, it was found that in the medical device package 10P of this embodiment (Example C), no detachment of the medical device 10a from the backing sheet 10b, damage to the backing sheet 10b, damage to the medical device 10a, or damage to the packaging bag 10d occurred.

[0129] Next, a transfer method for transferring the medical sheet 300 to a treatment target part of a living body will be described. Specifically, as shown in Figures 22 to 25, a transfer method for transferring the medical sheet 300 to a transplant target part 402 of a heart 400 (treatment target part of a living body) by thoracoscopic surgery will be described. As shown in Figure 17, the transfer method according to this embodiment includes a preparation step, a sheet placement step, a storage step, a positioning step, a deployment step, a movement step, and a removal step.

[0130] First, in a preparation step (step S1), the transfer device 11 according to the present embodiment is prepared. Hereinafter, the state shown in FIG. 2 will be described as the initial state of the transfer device 11. In the initial state, the first shaft 181 and the second shaft 221 are moved distally (in the direction of arrow X1) relative to the outer tube 17, and the first expandable body 26 and the second expandable body 50 are in a protruding position (second position) protruding distally from the distal opening 80 of the outer tube 17. The first expandable body 26 and the second expandable body 50 are exposed distally from the outer tube 17 and deployed, with the second expandable body 50 positioned on the first support surface 261 of the first expandable body 26. That is, the second expandable body 50 is positioned in a retracted position overlapping the first support surface 261 of the first expandable body 26. At this time, the base end of the carrier holding portion 54 is inserted into the first lumen 28 of the first shaft 181.

[0131] Next, in the sheet placement process (step S2), as shown in FIG. 18, the medical sheet 300 placed in the petri dish 401 is placed on the second support surface 74. As shown in FIG. 19, the medical sheet 300 protrudes outward from the second expandable body 50 when placed on the second support surface 74. The first support surface 261 supports the protruding portion 302 of the medical sheet 300 that protrudes outward from the second expandable body 50. The pair of second protrusions 40 suppress movement (misalignment) of the medical sheet 300 in the width direction of the intermediate support member 36 when the medical sheet 300 is placed on the second support surface 74.

[0132] Thereafter, in the accommodation step (step S3 in FIG. 17), the medical sheet 300 is accommodated in the outer tube 17 together with the first expandable body 26 and the second expandable body 50 to an accommodation position (first position) as shown in FIG. 20. Specifically, the first shaft 181 of the first carrier member 18 and the second shaft 221 of the second carrier member 22 are moved together in the proximal direction (direction of arrow X2) relative to the outer tube 17.

[0133] As a result, the base end support portion 34 is retracted in the base end direction from the distal end opening 80 of the outer tube 17. At this time, both tapered sides of the base end support portion 34 come into contact with the distal end opening 80 of the outer tube 17, and a force acts on the base end support portion 34 to curl the base end support portion 34 in the circumferential direction of the outer tube 17. As a result, the base end support portion 34 is smoothly retracted into the outer tube 17 while curling. At this time, the first expandable body 26 is accommodated in the outer tube 17 while curling into a conical shape so that the distal end side has a larger diameter and the base end support portion 34 has a smaller diameter.

[0134] When the base-end support portion 34 deforms, a force acts on the intermediate support portion 36, causing it to curl circumferentially around the outer tube 17, and the intermediate support portion 36 is pulled into the outer tube 17 while curling. At this time, the intermediate support portion 36 deforms into a cylindrical shape along the inner surface of the outer tube 17. Each of the pair of first protrusions 38 curves so that the surface 461 of the first expansion body 26 faces inward and the back surface 462 of the first expansion body 26 faces outward. As shown in FIG. 21 , the back surfaces 462 of the intermediate portions 443, which bulge outward in a convex shape in the radial direction, come into contact with each other on an imaginary line L extending perpendicular to the central axis of the outer tube 17. One first protrusion 38 and the other first protrusion 38 come into contact and are accommodated downward (first support surface 261, front surface 461).

[0135] As a result, the back surface 462 of the first expansion body 26 assumes a curved shape that adheres closely to the inner surface of the outer tube 17, and the tips of each first protrusion 38 further curve back toward the center of the outer tube 17, with the pair of tips positioned below the central axis of the outer tube 17. In other words, the first expansion body 26 curves into a heart shape that follows the inner surface of the outer tube 17.

[0136] The heart shape refers to a generally circular shape consisting of a convexly curved shape on one side and two convexly curved shapes on the opposite side. When a heart shape is formed in the lumen 171 of the tubular body (outer cylinder 17), the two convexly curved shapes that protrude toward each other along the inner surface of the tubular body approach each other and part of their circumferential surfaces come into contact with each other, resulting in an overall outline that is generally circular along the inner surface of the tubular body (see the shape of the first expansion body 26 in Figure 21).

[0137] As the first expandable body 26 bends and deforms, the second expandable body 50 also bends and deforms along the inside (surface 461 side) of the first expandable body 26. As the first expandable body 26 and the second expandable body 50 bend and deform, the medical sheet 300 deforms into a shape corresponding to the shapes of the first support body 32 and the second support body 72, and the medical sheet 300 is housed in the outer tube 17. The housing process is completed when the entire first expandable body 26 is completely inserted into the outer tube 17, as shown in FIG. 20 .

[0138] Thereafter, in the placement step (step S4 in FIG. 17), as shown in FIG. 22, the transport instrument 11 is inserted into the thoracic cavity 410 through the incision 409 in the chest 408. At this time, the tip of the transport instrument 11 is positioned near the transplant target site 402 in the heart 400, and the tip of the endoscope 14 is positioned inside the thoracic cavity 410.

[0139] Next, in the unfolding step (step S5 in FIG. 17), the first expandable body 26, the second expandable body 50, and the medical sheet 300 are unfolded as shown in FIG. 23. Specifically, in the unfolding step, the first shaft 181 is grasped and moved toward the distal end (in the direction of arrow X1) relative to the outer tube 17. As a result, the first valve body (not shown) causes the second shaft 221 to move integrally with the first shaft 181 toward the distal end (in the direction of arrow X1). At this time, the first shaft 181 and the second shaft 221 move integrally toward the distal end via the movement restricting member 24. Then, the first expandable body 26 exposed from the distal end opening 80 of the outer tube 17 returns to its original shape due to a restoring force. When the first expandable body 26 is unfolded in the second position, the second expandable body 50 and the medical sheet 300 spread out into a planar shape.

[0140] In the unfolding process, the second carrier member 22 has the second support surface 74, on which the medical sheet 300 is placed, positioned entirely above the first support surface 261. At this time, the medical sheet 300 is supported by the first support surface 261 and the second support surface 74. This prevents wrinkles from forming in the protruding portion 302 of the medical sheet 300 before the medical sheet 300 is transferred to the transplant recipient portion 402 of the heart 400.

[0141] Next, in the moving step (step S6 in FIG. 17), as shown in FIG. 24, the second carrier member 22 is moved in the distal direction (arrow X1 direction) relative to the first carrier member 18, so that the second expansion body 50 carrying the medical sheet 300 moves from the retracted position to the advanced position, and the second expansion body 50 protrudes in the distal direction (arrow X1 direction) beyond the distal end of the first expansion body 26. Specifically, in the moving step, the second shaft 221 is moved in the distal direction relative to the first shaft 181.

[0142] As a result, the second expansion body 50 moves distally (in the direction of arrow X1) relative to the first expansion body 26. At this time, when the pressing surface 58 of the carrier holding part 54 (pressing part 56) presses the outer peripheral end face of the medical sheet 300 distally, the entire medical sheet 300 is positioned distally of the first expansion body 26. In this movement process, the medical sheet 300 is moved above the transplantation target part 402 of the heart 400, and the protruding part 302 of the medical sheet 300 is brought into contact with the transplantation target part 402.

[0143] Then, in the removal step (step S7 in FIG. 17 ), as shown in FIG. 25 , the second carrier member 22 is moved from the second position to the first position to remove the second expansion body 50 from between the transplantation target area 402 and the medical sheet 300. This brings the entire medical sheet 300 into contact with the surface of the transplantation target area 402. This completes the transfer of the medical sheet 300 to the transplantation target area 402. The transfer device 11 is then removed from the chest 408 with the first expansion body 26 and the second expansion body 50 housed within the outer tube 17. As the second expansion body 50 moves proximally toward the tip of the first shaft 181, the proximal end of the second expansion body 50 fits into the notch 19. The notch 19 holds the second expansion body 50 at the tip of the first shaft 181. The notch 19 prevents the second expansion body 50 from peeling off.

[0144] This embodiment has the following advantages.

[0145] 1, the medical device holding structure 10c includes a mount 10b that holds the medical device 10a, and the multiple device holders 104 provided on the mount 10b include a first intermediate holder 1101 that is disposed between the first gripping portion 172 and the second gripping portion 29 of the medical device 10a. As a result, the first intermediate holder 1101 of the device holder 104 holds the medical device 10a between the first gripping portion 172 and the second gripping portion 29, thereby effectively preventing the medical device 10a from coming off the mount 10b during transportation or when the medical device 10a is dropped.

[0146] The multiple device holding sections 104 include a second intermediate holding section 1102 that is arranged closer to the base end than the first intermediate holding section 1101, and the second gripping section 29 is arranged between the first intermediate holding section 1101 and the second intermediate holding section 1102. With this configuration, the second gripping section 29 can be effectively positioned and held relative to the first gripping section 172 by the first intermediate holding section 1101 and the second intermediate holding section 1102 that are arranged on the tip end side and base end side of the second gripping section 29, respectively.

[0147] 11, when the medical device 10a is held by the mount 10b, the separation distance K between the first gripping portion 172 and the second gripping portion 29 is approximately equal to or greater than the thickness T (see FIG. 10A) of the mount 10b. This allows the first gripping portion 172 and the second gripping portion 29 to be disposed close to each other by the first intermediate holding portion 1101 and the second intermediate holding portion 1102. This allows the second intermediate holding portion 1102 to restrict movement of the first shaft 181, thereby preventing the second shaft 221 from moving in the proximal direction together with the first shaft 181, and therefore preventing bending of the second shaft 221 supported by the proximal end support portion 34.

[0148] As shown in FIG. 8, the first intermediate holding portion 1101 includes a first intermediate support piece 1301 standing on the holding surface 100a of the mount body 100, and as shown in FIG. 12A, the first intermediate support piece 1301 has a first intermediate support hole 1321 that supports the first shaft 181. As shown in FIG. 12B, the second intermediate holding portion 1102 includes a second intermediate support piece 1302 standing on the holding surface 100a of the mount body 100, and the second intermediate support piece 1302 has a second intermediate support hole 1322 that supports the second shaft 221. With this configuration, the first shaft 181 can be effectively held by the first intermediate support hole 1321 of the first intermediate support piece 1301. The second shaft 221 can be effectively held by the second intermediate support hole 1322 of the second intermediate support piece 1302.

[0149] 11, the outer diameter of first grip portion 172 is larger than the outer diameter of second grip portion 29. With this configuration, the user can easily grip first grip portion 172. The user can easily operate first shaft 181 using second grip portion 29.

[0150] 12A and 12B, the diameter of the first intermediate support hole 1321 is larger than the diameter of the second intermediate support hole 1322, and the second distance H2 from the holding surface 100a to the bottom of the second intermediate support hole 1322 is larger than the first distance H1 from the holding surface 100a to the bottom of the first intermediate support hole 1321. With this configuration, the outer tube 17 and the first shaft 181 can be held substantially parallel to the holding surface 100a. That is, the first gripping portion 172 contacts the holding surface 100a, but the second gripping portion 29 is spaced from the holding surface 100a, and the first gripping portion 172 and the second gripping portion 29 can be arranged on the same axis.

[0151] As shown in FIG. 8, the device holder 104 includes a plurality of hooks 112 that protrude from the mount body 100 and hold the outer tube 17. The hooks 112 have a fixed end 1341 that is supported by the mount body 100 and a free end 1342 that is provided on the opposite side of the fixed end 1341, and cover the outer tube 17 between the fixed end 1341 and the free end 1342. As shown in FIG. 1, when viewed from a direction perpendicular to the holding surface 100a, the outer tube 17 is located between the fixed end 1341 and the free end 1342. With this configuration, the outer tube 17 is held by the plurality of hooks 112, and therefore the medical device 10a can be effectively held by cooperation between the plurality of device holders 104 and the plurality of hooks 112.

[0152] The medical device 10a has a first expansion body 26 that can expand and contract and is located at the tip of the first shaft 181, and the mount 10b has a cover part 102 that is connected to the mount main body 100 and covers the first expansion body 26 of the medical device 10a. With this configuration, the cover part 102 can cover and protect the first expansion body 26, so that the first expansion body 26 can be held in a state where it is exposed to the outside of the outer tube 17.

[0153] The mount 10b has a mount body 100 having a holding surface 100a and a plurality of device holding portions 104 that hold the medical device 10a, and the plurality of device holding portions 104 are provided with a first intermediate holding portion 1101 that is disposed between the first gripping portion 172 and the second gripping portion 29 of the medical device 10a. With this configuration, the first intermediate holding portion 1101 of the device holding portion 104 holds the medical device 10a between the first gripping portion 172 and the second gripping portion 29, thereby effectively preventing the medical device 10a from coming off the mount 10b during transportation or when dropped.

[0154] The multiple device holding parts 104 include a second intermediate holding part 1102 that is arranged closer to the base end than the first intermediate holding part 1101. With this configuration, the first intermediate holding part 1101 and the second intermediate holding part 1102 that are arranged on the tip end side and base end side of the second gripping part 29 can effectively position and hold the second gripping part 29 relative to the first gripping part 172.

[0155] As shown in Fig. 8, the first intermediate holding portion 1101 includes a first intermediate support piece 1301 that stands on the holding surface 100a of the mount body 100 and holds the medical device 10a, and the second intermediate holding portion 1102 includes a second intermediate support piece 1302 that stands on the holding surface 100a of the mount body 100 and holds the medical device 10a. As shown in Fig. 11, the second intermediate support piece 1302 is cut out and raised from the mount body 100 toward the distal end so as to approach the first intermediate support piece 1301 and protrude from the holding surface 100a. With this configuration, the distal and proximal ends of the second gripping portion 29 can be effectively held by the first intermediate support piece 1301 and the second intermediate support piece 1302 that stand and protrude from the holding surface 100a. Compared to a configuration in which the first intermediate support piece 1301 and the second intermediate support piece 1302 are cut and raised in the same direction, a force acts on the first intermediate support piece 1301 and the second intermediate support piece 1302 to return them toward the holding surface 100a of the backing paper 10b, so that the first intermediate support piece 1301 applies a pressing force to the first gripping portion 172, and the second shaft 221 inserted into the first gripping portion 172 can be held in a manner that pulls it toward the tip.

[0156] 1, medical device package 10P includes medical device holding structure 10c including backing 10b that holds medical device 10a, packaging bag 10d that houses medical device holding structure 10c, and packaging box 10e that houses packaging bag 10d.
