[0021] The base 11 has a rectangular frame shape. The base 11 faces the floor surface. Casters 19 are provided on the base 11. The casters 19 enable the rack 10 to move on the floor surface.

[0022] The support pillar 12 is provided so as to extend upward from the rear end portion of the base 11. The support pillar 12 supports a base member 13.

[0023] The base member 13 is fixed to the upper part of the support 12. The base member 13 is long in the left-right direction. The base member 13 supports each of the multiple housings 2 arranged in the left-right direction. The base member 13 supports the multiple housings 2 of different sizes along the left-right direction. In this embodiment, the base member 13 supports two first housings 2A and ten second housings 2B. In the base member 13, the two first housings 2A are arranged adjacent to each other in the left-right direction. In the base member 13, the ten second housings 2B are arranged adjacent to each other in the left-right direction. The ten second housings 2B are arranged to the left of the two first housings 2A.

[0024] The base member 13 has an opposing surface 130 that faces the second surface 202 of the housing 2. In this embodiment, the opposing surface 130 is a substantially flat surface. The opposing surface 130 is inclined downward toward the front. In this embodiment, a first support member 131 and a second support member 132 are provided on the opposing surface 130 of the base member 13. The first support member 131 supports a portion of the housing 2 from the lower side. The second support member 132 supports a portion of the housing 2 from the upper side.

[0025] Fig. 4 is a perspective view showing the first support member 131 and the second support member 132 according to this embodiment.

[0026] The base member 13 has an injection port 6 facing the receiving port 5 of the housing 2. The injection port 6 is provided on the facing surface 130. The injection port 6 has a protruding member 6A protruding from the facing surface 130 and two injection ports 6B provided on the protruding member 6A. A plurality of injection ports 6 are provided on the facing surface 130 at intervals in the left-right direction. The number of injection ports 6 provided is the same as the number of housings 2 that the base member 13 can support. The injection port 6 faces the receiving port 5 of each of the housings 2. In this embodiment, twelve injection ports 6 are provided at intervals in the left-right direction. One injection port 6 faces the receiving port 5 of one housing 2.

[0027] The jet port 6 jets the cleaning liquid while facing the receiving port 5. The cleaning liquid jetted from the jet opening 6B of the jet port 6 is poured into the receiving port 5.

[0028] In cleaning the inside of the surgical instrument 1, cleaning liquid is supplied from the injection port 6 of the rack 10 to the receiving port 5. The cleaning liquid supplied to the receiving port 5 flows inside the housing 2 and then flows into a tube arranged inside the hollow shaft 3. The cleaning liquid that flows into the tube flows toward the tip of the hollow shaft 3. The cleaning liquid supplied to the tip of the hollow shaft 3 flows toward the housing 2 through a flow path between the outer circumferential surface of the tube and the inner circumferential surface of the hollow shaft 3. The cleaning liquid that flows through the flow path between the outer circumferential surface of the tube and the inner circumferential surface of the hollow shaft 3 flows out from a gap provided in the housing 2. Note that a part of the cleaning liquid injected from the receiving port 5 and supplied to the tip of the hollow shaft 3 may flow out from the tip of the hollow shaft 3.

[0029] The tubular member 14 is disposed forward of the base member 13. The treatment tool 4 is inserted into the tubular member 14. A plurality of tubular members 14 are provided at intervals in the left-right direction. The number of tubular members 14 provided is the same as the number of injection ports 6. In this embodiment, twelve tubular members 14 are provided at intervals in the left-right direction. One treatment tool 4 is connected to one tubular member 14.

[0030] The arm member 15 is rotatably supported by the base member 13. In this embodiment, the arm member 15 includes a first arm member 15A and a second arm member 15B. The first arm member 15A is rotatably supported by the left end portion of the base member 13. The second arm member 15B is rotatably supported by the right end portion of the base member 13.

[0031] The rod member 16 is connected to the arm member 15. The rod member 16 rotates together with the arm member 15. The rod member 16 is disposed above each of the housings 2 by the rotation of the arm member 15. The arm member 15 rotates between a first position where the rod member 16 is disposed above the housing 2 and a second position where the rod member 16 is disposed rearward of the base member 13. FIG. 2 shows a state where the arm member 15 is rotated to the second position and the rod member 16 is disposed rearward of the base member 13. FIG. 3 shows a state where the arm member 15 is rotated to the first position and the rod member 16 is disposed above each of the twelve housings 2.

[0032] In this embodiment, the state in which the rod member 16 is disposed above each of the multiple housings 2 includes a state in which the rod member 16 faces the third surface 203 of the housing 2. The state in which the rod member 16 is disposed above each of the multiple housings 2 includes a state in which the rod member 16 faces the opposing surface 130 when the housings 2 are not supported by the base member 13.

[0033] In this embodiment, when the rod members 16 are disposed above the respective housings 2 by the rotation of the arm members 15, the distances between the rod members 16 and the base member 13 are different.

[0034] In this embodiment, the rod member 16 includes a first rod member 16A and a second rod member 16B. The first rod member 16A and the second rod member 16B are disposed at different positions in the left-right direction. In this embodiment, the first rod member 16A is disposed to the right of the second rod member 16B. In a state in which the rod member 16 is disposed above each of the housings 2, the first rod member 16A faces the first region 130A of the opposing surface 130, and the second rod member 16B faces the second region 130B of the opposing surface 130. The first region 130A is defined to the right of the second region 130B.

[0035] In this embodiment, the distance between the first rod member 16A and the first region 130A of the opposing surface 130 is different from the distance between the second rod member 16B and the second region 130B of the opposing surface 130. In this embodiment, the distance between the first rod member 16A and the first region 130A of the opposing surface 130 is longer than the distance between the second rod member 16B and the second region 130B of the opposing surface 130.

[0036] The distance between the rod member 16 and the opposing surface 130 of the base member 13 includes the distance between the rod member 16 and the opposing surface 130 of the base member 13 in the normal direction of the opposing surface 130. In this embodiment, the opposing surface 130 is a substantially flat surface. When the rod member 16 is disposed above each of the multiple housings 2, the first rod member 16A is farther from the opposing surface 130 than the second rod member 16B.

[0037] The first rod member 16A and the second rod member 16B are disposed so as to extend in the left-right direction. The right end of the first rod member 16A is connected to the first arm member 15A. The left end of the second rod member 16B is connected to the second arm member 15B. In this embodiment, the rod member 16 includes a bent rod member 16C that connects the left end of the first rod member 16A and the right end of the second rod member 16B. The first rod member 16A, the second rod member 16B, and the bent rod member 16C are integral with each other.

[0038] When the rod member 16 is disposed above each of the housings 2, the first rod member 16A is disposed above two first housings 2A, the second rod member 16B is disposed above ten second housings 2B, and the bent rod member 16C is disposed so as to extend in the normal direction of the opposing surface 130. When the rod member 16 is disposed above each of the housings 2, the first rod member 16A faces the third surface 203 of the first housing 2A, and the second rod member 16B faces the third surface 203 of the second housing 2B.

[0039] The first liquid supply pipe 17 is connected to the base member 13. The cleaning liquid is supplied to the injection port 6 via the first liquid supply pipe 17.

[0040] The second liquid supply pipe 18 is connected to the tubular member 14. The cleaning liquid is supplied to the tubular member 14 via the second liquid supply pipe 18. An injection nozzle is provided inside the tubular member 14. The injection nozzle injects the cleaning liquid supplied from the second liquid supply pipe 18 into the inside of the tubular member 14.

[0041] FIG. 5 is a schematic diagram showing the surgical instrument 1 and the rack 10 in a state in which the ejection port 6 and the receiving port 5 according to this embodiment face each other. The housing 2 is supported by the first support member 131 and the second support member 132, so that the receiving port 5 and the ejection port 6 are positioned. The arm member 15 is supported by the base member 13 so as to be rotatable about the rotation axis 7. As described above, the arm member 15 rotates between a first position in which the rod member 16 is disposed on the upper side of the housing 2 and a second position in which the rod member 16 is disposed on the rear side of the base member 13. The rod member 16 is disposed on the upper side of the housing 2 by rotating the arm member 15 to the first position. The rod member 16 is retracted from the upper side of the housing 2 by rotating the arm member 15 to the second position.

[0042] As shown in Fig. 5, when the cleaning liquid is injected from the injection port 6 into the receiving port 5, the receiving port 5 and the injection port 6 face each other, and the rod member 16 is disposed on the upper side of the housing 2, and the cleaning liquid is injected from the injection port 6. When the cleaning liquid is injected from the injection port 6 into the receiving port 5, at least a part of the protruding member 6A of the injection port 6 may be disposed inside the receiving port 5, or the protruding member 6A may be disposed outside the receiving port 5. The protruding member 6A of the injection port 6 and the housing 2 may be in contact with each other or may be separated from each other. When the cleaning liquid is injected from the injection port 6 into the receiving port 5, the second surface 202 of the housing 2 faces the opposing surface 130 of the base member 13, and the rod member 16 faces the third surface 203.

[0043] When cleaning liquid is sprayed from the spray port 6, in a predetermined direction perpendicular to both the spray direction of the cleaning liquid and the left-right direction, the rod member 16 is positioned closer to the hollow shaft 3 than the rotation axis 7 of the arm member 15 and at a position overlapping with the housing 2. In this embodiment, the spray direction of the cleaning liquid from the spray port 6 is substantially parallel to the normal direction of the opposing surface 130. The predetermined direction is substantially parallel to the extension direction of the hollow shaft 3. The predetermined direction is substantially parallel to the opposing surface 130 in a cross section perpendicular to the left-right axis parallel to the left-right direction.

[0044] According to this embodiment, the rack 10 prevents the housing 2 from moving away from the ejection port 6 by the rod member 16 when the surgical instrument 1 is washed. Preventing the housing 2 from moving away from the ejection port 6 includes restricting the movement of the housing 2 upward. The rack 10 restricts the movement of the housing 2 upward by the rod member 16 when the surgical instrument 1 is washed. That is, even if the pressure of the cleaning liquid sprayed from the ejection port 6 to the receiving port 5 is high when the surgical instrument 1 is washed, the rod member 16 is disposed on the upper side of the housing 2, so that the surgical instrument 1 is prevented from coming off the rack 10. When the cleaning liquid is sprayed from the ejection port 6, the rod member 16 is disposed in a position forward of the rotation axis 7 of the arm member 15 and facing the third surface 203 of the housing 2, so that even if the pressure of the cleaning liquid sprayed from the ejection port 6 to the receiving port 5 is high, the rod member 16 holds the housing 2, so that the surgical instrument 1 is prevented from coming off the rack 10. That is, the rod member 16 prevents the housing 2 from rising up from the base member 13. When the rod member 16 is disposed above the housing 2, the rod member 16 may be in contact with the housing 2 or may be separated from the housing 2.

[0045] <Cleaning equipment> 6 is a schematic diagram showing the relationship between the rack 10 and the cleaning device 50 according to this embodiment. The rack 10 is housed in a cleaning tank 51 of the cleaning device 50 with a surgical instrument 1 supported thereon. An entrance 52 is provided on the left side of the cleaning tank 51. A shower spray 53 is provided on the ceiling of the cleaning tank 51. The rack 10 is carried from the outside to the inside of the cleaning tank 51 through the entrance 52.

[0046] 6, the rack 10 can pass through the entrance 52 of the cleaning tank 51 when the arm member 15 is located at the first position. The rack 10 cannot pass through the entrance 52 of the cleaning tank 51 when the arm member 15 is located at the second position. In other words, when the arm member 15 is located at the second position, even if an attempt is made to carry the rack 10 into the cleaning tank 51 through the entrance 52, the arm member 15 located at the second position gets caught on the left wall surface of the cleaning tank 51 around the entrance 52, and therefore the user of the cleaning apparatus 50 cannot carry the rack 10 into the cleaning tank 51 through the entrance 52.

[0047] When a user of the cleaning device 50 carries the rack 10 into the cleaning tank 51 through the entrance 52, the user rotates the arm member 15 to the first position. By rotating the arm member 15 to the first position, when the rack 10 is carried into the cleaning tank 51 through the entrance 52, the rack 10 does not get caught on the left wall of the cleaning tank 51 around the entrance 52. The user can carry the rack 10 into the cleaning tank 51. Furthermore, by rotating the arm member 15 to the first position, the rack 10 supporting the surgical instrument 1 is carried into the cleaning tank 51 with the rod member 16 disposed on the upper side of the housing 2.

[0048] After the rack 10 is carried into the inside of the washing tank 51, a washing liquid supply port (not shown) provided inside the washing tank 51 is connected to the first liquid supply pipe 17 and the second liquid supply pipe 18, respectively.

[0049] The cleaning liquid supplied from the cleaning liquid supply port to the first supply pipe 17 is sprayed from the spray port 6. The cleaning liquid sprayed from the spray port 6 is supplied to the receiving port 5. By supplying the cleaning liquid to the receiving port 5, the inside of the surgical instrument 1 is cleaned with the cleaning liquid. Since the rod member 16 is disposed on the upper side of the housing 2, the surgical instrument 1 is prevented from coming off the rack 10 inside the cleaning tank 51.

[0050] The cleaning liquid supplied from the cleaning liquid supply port to the second liquid supply pipe 18 is sprayed from the spray nozzle provided inside the tubular member 14. By spraying the cleaning liquid from the spray nozzle, the treatment tool 4 inserted in the tubular member 14 is washed with the cleaning liquid.

[0051] Furthermore, the cleaning liquid is sprayed from the shower spray 53, so that the outer surfaces of the surgical instruments 1 supported on the rack 10 are cleaned with the cleaning liquid.

[0052] <Effects> As described above, the rack 10 supports the surgical instrument 1 to be cleaned, which includes the housing 2 having the receiving port 5, the hollow shaft 3 extending from the housing 2, and the treatment tool 4 provided at the tip of the hollow shaft 3. The rack 10 supports a plurality of housings 2 (2A, 2B) of different sizes along the left-right direction (first direction), and includes a base member 13 having a plurality of ejection ports 6 facing each of the receiving ports 5, a tubular member 14 disposed forward (on one side) of the base member 13 in the front-rear direction (second direction) perpendicular to the left-right direction and into which the treatment tool 4 is inserted, an arm member 15 rotatably supported by the base member 13, and a rod member 16 connected to the arm member 15. When the rod member 16 is disposed above each housing 2 by rotating the arm member 15, the distance between the rod member 16 and the base member 13 is different. The rack 10 prevents the housing 2 from moving away from the ejection port 6 by the rod member 16 when the object to be cleaned is cleaned. Preventing the housing 2 from moving away from the injection port 6 includes restricting movement of the housing 2 in the left-right direction and the up-down direction (third direction) perpendicular to the front-rear direction.

[0053] According to this embodiment, even if the pressure of the cleaning liquid injected from the injection port 6 to the receiving port 5 is high, the rod member 16 is disposed on the upper side of the housing 2, so that the surgical instrument 1 is prevented from coming off the rack 10 during cleaning of the surgical instrument 1. That is, the rod member 16 prevents the housing 2 from floating up from the base member 13. Since the surgical instrument 1 is prevented from coming off from the rack 10, the occurrence of poor cleaning of the surgical instrument 1 is prevented. Also, according to this embodiment, when the rod member 16 is disposed on the upper side of each of the multiple housings 2 by the rotation of the arm member 15, the distance between the rod member 16 and the base member 13 is different. This allows multiple types of surgical instruments 1 to be washed simultaneously. During cleaning of the surgical instrument 1, multiple housings 2 of different sizes are prevented from floating up from the base member 13.

[0054] The rod member 16 includes a first rod member 16A and a second rod member 16B. Since the distance between the first rod member 16A and the first region 130A and the distance between the second rod member 16B and the second region 130B are different, multiple types of surgical instruments 1 can be washed simultaneously. In this embodiment, the distance between the first rod member 16A and the first region 130A is longer than the distance between the second rod member 16B and the second region 130B. The first housing 2A of the first surgical instrument 1A, which has a large outer dimension, is disposed between the first rod member 16A and the first region 130A. The second housing 2B of the second surgical instrument 1B, which has a small outer dimension, is disposed between the first rod member 16A and the first region 130A. The first rod member 16A can suppress the first housing 2A from floating up from the first region 130A. The second rod member 16B can prevent the second housing 2B from rising up from the second region 130B.

[0055] The first rod member 16A and the second rod member 16B are disposed at different positions in the left-right direction. This allows the first surgical instrument 1A and the second surgical instrument 1B to be simultaneously washed while preventing the first housing 2A and the second housing 2B from floating up from the base member 13, with the first surgical instrument 1A and the second surgical instrument 1B aligned in the left-right direction.

[0056] In this embodiment, the opposing surface 130 is a flat surface. The first region 130A and the second region 130B are disposed substantially in the same plane (flush). When the rod member 16 is disposed above each of the housings 2, the first rod member 16A is farther away from the opposing surface 130 than the second rod member 16B. Since the opposing surface 130 is a flat surface, the shape of the base member 13 is prevented from becoming complicated.

[0057] The arm member 15 includes a first arm member 15A to which the right end (one end) of the first rod member 16A is connected, and a second arm member 15B to which the left end (the other end) of the second rod member 16B is connected. The rod member 16 includes a bent rod member 16C that connects the left end (the other end) of the first rod member 16A and the right end (one end) of the second rod member 16B. The first rod member 16A, the second rod member 16B, and the bent rod member 16C are integral with each other. This allows the rod member 16 to be manufactured by simply bending one rod-shaped member.

[0058] With the receiving port 5 and the ejection port 6 facing each other and with the rod member 16 disposed above the housing 2, the cleaning liquid is ejected from the ejection port 6. When the cleaning liquid is ejected from the ejection port 6, in a predetermined direction perpendicular to each of the ejection direction of the cleaning liquid and the left-right direction (first direction), the rod member 16 is disposed at a position closer to the hollow shaft 3 than the rotation axis 7 of the arm member 15 and at a position overlapping with the housing 2. This effectively prevents the housing 2 from floating up from the base member 13.

[0059] The tubular member 14 is disposed forward (on one side) of the base member 13 in a front-rear direction (second direction) perpendicular to the left-right direction (first direction). The arm member 15 rotates between a first position where the rod member 16 is disposed above the housing 2 and a second position where the rod member 16 is disposed rearward (on the other side) of the base member 13 in the front-rear direction (second direction). The rotation of the arm member 15 to the first position prevents the housing 2 from floating up from the base member 13. The rotation of the arm member 15 to the second position allows the user of the rack 10 to smoothly remove the housing 2 from the base member 13.

[0060] The rack 10 can pass through the entrance 52 provided in the cleaning tank 51 of the cleaning device 50 when the arm member 15 is arranged at the first position. The rack 10 cannot pass through the entrance 52 provided in the cleaning tank 51 of the cleaning device 50 when the arm member 15 is arranged at the second position. This prevents the rack 10 from being carried into the cleaning tank 51 when the rod member 16 is not arranged above each of the housings 2. That is, the cleaning liquid is prevented from being sprayed from the spray port 6 to the receiving port 5 inside the cleaning tank 51 when the rod member 16 is not arranged above each of the housings 2. This prevents the rack 10 from being carried into the cleaning tank 51 when the user of the cleaning device 50 forgets to arrange the rod member 16 above the housing 2.
