[0008] A plurality of modular cleaning units, the modular cleaning units are detachably arranged on the fixed support, and a water flow path is formed inside the modular cleaning unit, and the inlet of the water flow path is formed on the first side surface of the modular cleaning unit;

[0009] A water outlet joint, the water outlet joint is arranged at the water outlet of the water pipe path, and the water outlet joint includes a connecting pipe, an elastic member and a fixing plate. The fixing plate is fixed on the fixed support. One end of the elastic member abuts against the fixing plate and the other end abuts against the connecting pipe. The connecting pipe can move between a first position and a second position, and an opening is formed on the outer peripheral wall of the connecting pipe;

[0010] When installing the module cleaning unit, the second side of the module cleaning unit facing away from the first side abuts against the fixed support, the inlet of the water supply pipeline is communicated with the connecting pipe, and the first side of the module cleaning unit abuts against the connecting pipe and pushes the connecting pipe to the first position against the elastic force of the elastic member. At this time, the connecting pipe is communicated with the water passing pipeline through the opening;

[0011] When removing the module cleaning unit, the connecting pipe moves to the second position under the elastic force of the elastic member. At this time, the connecting pipe is in a blocked state with the water passing pipeline.

[0012] Furthermore, a first limiting plate is convexly provided on the outer peripheral wall of the connecting pipe. When installing the module cleaning unit, the first side of the module cleaning unit abuts against one side of the first limiting plate, and the other end of the elastic member abuts against the other side of the first limiting plate.

[0013] Furthermore, the connecting pipe passes through the outer peripheral walls of the fixing plate and the water passing pipeline at the same time, and a second limiting plate is fixed at the end of the connecting pipe close to the opening. When removing the module cleaning unit, the connecting pipe moves to the second position under the elastic force of the elastic member. At this time, the second limiting plate abuts against the inner wall forming the water passing pipeline.

[0014] Furthermore, the plurality of module cleaning units include a short instrument cleaning unit and a long instrument cleaning unit.

[0035] The technical solution of the invention will be further described in detail below in conjunction with the preferred embodiments and their accompanying drawings in a non-limiting manner. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically defined. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation of the present invention.

[0036] As Figures 1 - 7 shown, a cleaning rack for minimally invasive surgical instruments according to an embodiment of the present invention includes a fixed support 1 and a plurality of modular cleaning units 2. The modular cleaning units 2 are used for loading minimally invasive surgical instruments, and the modular cleaning units 2 are detachably arranged on the fixed support 1. A water pipe passage 30 is formed in the fixed support 1, and an inlet 7 of the water pipe passage 30 is used to connect to the water supply interface of a cleaning machine; a water pipe passage 31 is formed in the modular cleaning unit 2, and an inlet 32 of the water pipe passage 31 is formed on a first side surface 33 of the modular cleaning unit 2; when the modular cleaning unit 2 is installed on the fixed support 1, the inlet 32 of the water pipe passage 31 communicates with the outlet of the water pipe passage 30. During cleaning, the cleaning liquid in the cleaning machine flows from the water supply interface of the cleaning machine into the water pipe passage 30, flows out from the outlet of the water pipe passage 30 and enters the water pipe passage 31, and finally sprays out from the spray opening of the water pipe passage 31 to clean the minimally invasive surgical instruments. In this embodiment, by modularizing the modular cleaning unit 2 and the modular cleaning unit 2 can be detached from the fixed support 1, it is convenient to place or install the minimally invasive surgical instruments to be cleaned into the modular cleaning unit 2. After the minimally invasive surgical instruments are placed or installed, the entire modular cleaning unit 2 is assembled onto the fixed support 1. This design is convenient for placing the minimally invasive surgical instruments to be cleaned, with simple and fast operation. In addition, a plurality of modular cleaning units 2 with modular design can be arranged in sequence on the fixed support 1, and the whole structure is compact, improving the loading capacity of the fixed support 1 for the minimally invasive surgical instruments to be cleaned.

[0037] The cleaning rack further includes a water outlet joint 8. The water outlet joint 8 is arranged at the water outlet of the water pipe 30, and the water outlet joint 8 includes a connecting pipe 17, an elastic member 18 and a fixing plate 19. The fixing plate 19 is fixed on the fixed support 1. One end of the elastic member 18 abuts against the fixing plate 19 and the other end abuts against the connecting pipe 17. The connecting pipe 17 can move between a first position and a second position, and an opening 21 is formed on the outer peripheral wall of the connecting pipe 17. When installing the module cleaning unit 2, the second side 34 of the module cleaning unit 2 facing away from the first side 33 abuts against the fixed support 1. The inlet 32 of the water pipe 31 is communicated with the connecting pipe 17, and the first side 33 of the module cleaning unit 2 abuts against the connecting pipe 17 and pushes the connecting pipe 17 to the first position against the elastic force of the elastic member 18. At this time, the connecting pipe 17 is communicated with the water pipe 30 through the opening 21. When removing the module cleaning unit 2, the connecting pipe 17 moves to the second position under the elastic force of the elastic member 18. At this time, the connecting pipe 17 is in a blocked state with the water pipe 30. By arranging the water outlet joint 8 between the water pipe 30 of the fixed support 1 and the water pipe 31 of the module cleaning unit 2, it is ensured that only when the module cleaning unit 2 is installed, the cleaning liquid in the water pipe 30 can flow out from the water outlet joint 8 and enter the water pipe 31 to clean the minimally invasive surgical instruments on the module cleaning unit 2. When the module cleaning unit 2 is not installed, the corresponding water outlet joint 8 is in a blocked state, greatly saving water resources.

[0038] A first limiting plate 170 protrudes from the outer peripheral wall of the connecting pipe 17. When installing the module cleaning unit 2, the first side 33 of the module cleaning unit 2 abuts against one side of the first limiting plate 170, and the elastic member 18 is sleeved on the connecting pipe 17 and the other end of the elastic member 18 abuts against the other side of the first limiting plate 170. Additionally, setting the first limiting plate 170 increases the contact surface between the first side 33 of the module cleaning unit 2 and the connecting pipe 17, making it more stable when the module cleaning unit 2 pushes the connecting pipe 17.

[0039] The connecting pipe 17 passes through the fixing plate 19 and the outer peripheral wall of the water pipe 30 at the same time, and a second limiting plate 171 is fixed at the end of the connecting pipe 17 close to the opening 21. When removing the module cleaning unit 2, the connecting pipe 17 moves to the second position under the elastic force of the elastic member 18. At this time, the second limiting plate 171 abuts against the inner wall 310 forming the water pipe 30 to prevent the connecting pipe 17 from detaching from the water pipe 30.

[0040] A plurality of sequentially arranged instrument support frames 6 are further provided on the fixed support 1. The instrument support frames 6 are inclined relative to the vertical plane and are used to support the module cleaning unit 2. In addition, a retaining edge 60 is formed at the outer bottom of the instrument support frame 6, and the retaining edge 60 abuts against the second side surface 34 of the module cleaning unit 2. When the module cleaning unit 2 is installed in place, the first side surface 33 of the module cleaning unit 2 abuts against the first limiting plate 170 on the connecting pipe 17, and the second side surface 34 of the module cleaning unit 2 abuts against the retaining edge 60, preventing the module cleaning unit 2 from shaking or shifting left and right during the cleaning process.

[0041] In this embodiment, two module cleaning units 2 can be placed on the same instrument support frame 6, and the instrument support frame 6 has a pipeline communicated with the water supply pipeline 30, and a plurality of spray nozzles are provided on the instrument support frame 6.

[0042] The water supply pipeline 30 includes a main pipeline 300. The axial direction of the main pipeline 300 is consistent with the arrangement direction of the plurality of instrument support frames 6. A plurality of water outlet connectors 8 are provided, and the plurality of water outlet connectors 8 are symmetrically distributed on both sides of the main pipeline 300. Two water outlet connectors 8 located in the same radial direction respectively correspond to the two module cleaning units 2 on the same instrument support frame 6.

[0043] In this embodiment, a basket 3 is further provided on the fixed support 1 below the instrument support frame 6. The basket 3 is used to load small instruments and small parts.

[0044] The instrument support frame 6 includes an extension arm 5 for supporting the bottom of the module cleaning unit 2. Other parts of the instrument support frame 6 except the extension arm 5 are inclined to support the back of the module cleaning unit 2. In addition, in this embodiment, the retaining edge 60 is formed at the end of the extension arm 5, and the extension arm 5 is located above the basket 3. The extension arm 5 has a pipeline communicated with the water supply pipeline 30, and a plurality of spray nozzles are provided on the extension arm 5. The plurality of spray nozzles are respectively oriented towards the module cleaning unit 2 and the basket 3.

[0045] A guardrail assembly 4 is further provided at the outer edge of the instrument support frame 6. The guardrail assembly 4 includes an open state and a closed state. When the guardrail assembly 4 is in the closed state, the guardrail assembly 4 can prevent the module cleaning unit 2 from detaching from the instrument support frame 6.

[0046] Such as Figure 10As shown, the guardrail assembly 4 includes a guardrail 40, a railing hook 41, a spring 42, and a fixing bracket 43. The guardrail 40 is located outside the instrument support frame 6, and one end of the guardrail 40 is hinged to the instrument support frame 6. The fixing bracket 43 is fixed on the fixed support 1 and is located at the other end of the guardrail 40. One end of the spring 42 abuts against the guardrail 40, and the other end abuts against the railing hook 41. The railing hook 41 is arranged at the other end of the guardrail 40 and can move between a first position and a second position. When the user wants to close the guardrail assembly 4, the user pulls the railing hook 41 from the first position to the second position. At this time, the spring 42 is in a compressed state. When the guardrail 40 rotates to the closed position, the user releases the railing hook 41, and the railing hook 41 returns to the first position under the elastic force of the spring 42. At this time, the railing hook 41 is clamped with the fixing bracket 43, and finally the closing of the guardrail assembly 4 is completed.

[0047] Among them, the railing hook 41 is integrally formed and includes a telescopic portion 410 and a bent portion 411 that is mated with the fixing bracket 43. A first limit block 400 and a second limit block 401 are arranged on the guardrail 40. The telescopic portion 410 passes through the first limit block 400 and the second limit block 401 at the same time, and a convex block 412 is convexly provided on the telescopic portion 410. The convex block 412 is located between the first limit block 400 and the second limit block 401. The spring 42 is sleeved on the telescopic portion 410, and one end abuts against the convex block 412 and the other end abuts against the second limit block 401.

[0048] As Figure 8 and Figure 9 As shown, in this embodiment, the multiple module cleaning units 2 include a short instrument cleaning unit 9 and a long instrument cleaning unit 10. A plurality of first micro-invasive connectors 12 that are communicated with the water supply pipeline 31 and are arranged in sequence along the direction of the water supply pipeline 31 are provided on the short instrument cleaning unit 9. A plurality of second micro-invasive connectors 14 that are communicated with the water supply pipeline 31 and are arranged in sequence along the direction of the water supply pipeline 31 are provided on the long instrument cleaning unit 10. A plurality of spray ports are formed on the outer peripheral surfaces of the first micro-invasive connector 12 and the second micro-invasive connector 14. The cleaning liquid will be sprayed out from the spray ports to clean the instruments, especially the lumen-type minimally invasive instruments (the lumen-type instruments need to clean the inner surface and the outer surface).

[0049] In order to facilitate the transportation of the cleaning rack, a plurality of wheels 100 are further provided at the bottom of the fixed support 1.

[0050] The above-described embodiments only represent several implementation manners of the present invention.
