At the same time, when the flushing tube 11 is moved, the positioning component 13 is driven to rub against the inner wall of the laparoscope rod to scrub the inner wall of the laparoscope rod, thereby achieving a more effective cleaning effect.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Embodiment 1

[0040] The embodiment of the invention discloses a laparoscopic instrument pretreatment and cleaning device.

[0041] According to the attached Figure 1-9 As shown, including:

[0042] A flushing unit 1, comprising a flushing tube 11, a connecting assembly 12 and a positioning assembly 13, wherein the connecting assembly 12 and the positioning assembly 13 are respectively mounted on the end and the outside of the flushing tube 11, and after the flushing tube 11 is inserted into the laparoscope rod, the inner wall of the laparoscope rod is flushed with external cleaning fluid, and after the flushing tube 11 is inserted into the laparoscope rod, the positioning assembly 13 abuts against the inner wall of the laparoscope rod, and the flushing tube 11 is centrally positioned, so as to facilitate flushing of the inner wall of the laparoscope rod, and when the flushing tube 11 is moved, the positioning assembly 13 is driven to rub against the inner wall of the laparoscope rod to scrub the inner wall of the laparoscope rod;

[0043] The liquid supply unit is connected to the connecting assembly 12 , and the cleaning liquid is injected into the flushing tube 11 after the flushing tube 11 extends into the laparoscope rod.

[0044] During use, the flushing tube 11 is inserted into the laparoscope rod. At this time, the positioning component 13 is against the inner wall of the laparoscope rod, and the flushing tube 11 is centrally positioned in the laparoscope rod. At this time, the external cleaning fluid is injected into the flushing tube 11, and the inner wall of the laparoscope rod can be flushed. At this time, the flushing tube 11 will not fit the inner wall of the laparoscope rod, so as to facilitate the flushing of the inner wall of the laparoscope rod. At the same time, when the flushing tube 11 is moved, the positioning component 13 is driven to rub against the inner wall of the laparoscope rod to scrub the inner wall of the laparoscope rod, thereby achieving a more effective cleaning effect.

[0045] Furthermore, the flushing tube 11 includes a hose body 111 and flushing holes 112 , and a plurality of flushing holes 112 are obliquely and evenly opened on the outer side of the hose body 111 .

[0046] Through the multiple flushing holes 112, after the liquid supply unit injects cleaning liquid into the hose body 111, it can be discharged outward. After entering the flushing hole 112 with a smaller diameter, the flow rate of the water flow will increase, which will cause the water flow to be inclined and ejected outward with a greater intensity. After the inclined water flow contacts the inner wall of the laparoscope rod, a better flushing effect can be achieved.

[0047] Specifically disclosed, the connecting assembly 12 includes a rotating ring 121 and a connecting ring 122. The rotating ring 121 is fixedly sleeved on the end of the hose body 111. One end of the connecting ring 122 is connected to the liquid supply unit, and the other end of the connecting ring 122 is rotatably connected to the rotating ring 121.

[0048] By means of the rotating ring 121 and the connecting ring 122, the connecting ring 122 is connected to the liquid supply unit, and the rotating ring 121 can rotate relative to the connecting ring 122, so that the hose body 111 can be driven to rotate when the rotating ring 121 is rotated, and then after the hose body 111 is inserted into the laparoscope rod, the hose body 111 is rotated so that the multiple positioning components 13 rotate on the inner wall of the laparoscope rod, and when the hose body 111 is pushed to move along the axis, the multiple positioning components 13 can be moved along the axis on the inner wall of the laparoscope rod, so that the inner wall of the laparoscope rod can be fully scrubbed by the moving multiple positioning components 13.

[0049] Furthermore, a limiting groove is provided on the inner wall of the rotating collar 121 , and the end of the connecting collar 122 is fixedly connected to the limiting ring 123 , and the limiting ring 123 is rotatably disposed on the inner wall of the limiting groove.

The connecting section 1322 can be used to enable the arc segment 1321 to be installed between the two mounting rings 131. After the positioning assembly 13 is inserted into the laparoscope rod, the plurality of arc segments 1321 are compressed so that the plurality of arc segments 1321 can realize adaptive deformation according to the inner diameter of the laparoscope rod, and thus can be fitted in laparoscope rods of different sizes. At the same time, the hose body 111 inside the plurality of arc segments 1321 can be centered. At this time, the hose body 111 will not contact the inner wall of the laparoscope rod, and thus an effective cleaning effect can be achieved when the water flows out through the flushing hole 112.

[0053] Furthermore, the outer ring of the arc segment 1321 is fixedly sleeved with a brush sleeve 133. Through the provided brush sleeve 133, after the positioning assembly 13 is inserted into the laparoscope rod, the multiple arc segments 1321 fit with the inner wall of the laparoscope rod through the brush sleeve 133, and then when the hose body 111 is moved, the brush sleeve 133 can brush the inner wall of the laparoscope rod.

At this time, the external cleaning fluid is injected into the flushing tube 11, and the inner wall of the laparoscope rod can be flushed. At this time, the flushing tube 11 will not fit the inner wall of the laparoscope rod, so as to facilitate the flushing of the inner wall of the laparoscope rod. At the same time, when the flushing tube 11 is moved, the positioning component 13 is driven to rub against the inner wall of the laparoscope rod to scrub the inner wall of the laparoscope rod, thereby achieving a more effective cleaning effect.

[0055] Through the multiple flushing holes 112, after the liquid supply unit injects cleaning liquid into the hose body 111, it can be discharged outward. After entering the flushing hole 112 with a smaller diameter, the flow rate of the water flow will increase, which will cause the water flow to be inclined and ejected outward with a greater intensity. After the inclined water flow contacts the inner wall of the laparoscope rod, a better flushing effect can be achieved.

[0056] By means of the rotating ring 121 and the connecting ring 122, the connecting ring 122 is connected to the liquid supply unit, and the rotating ring 121 can rotate relative to the connecting ring 122, so that the hose body 111 can be driven to rotate when the rotating ring 121 is rotated, and then after the hose body 111 is inserted into the laparoscope rod, the hose body 111 is rotated so that the multiple positioning components 13 rotate on the inner wall of the laparoscope rod, and when the hose body 111 is pushed to move along the axis, the multiple positioning components 13 can be moved along the axis on the inner wall of the laparoscope rod, so that the inner wall of the laparoscope rod can be fully scrubbed by the moving multiple positioning components 13.

[0057] By using the provided mounting rings 131, two mounting rings 131 are sleeved on the outside of the hose body 111, and one of the mounting rings 131 is fixedly provided on its outside, while the other mounting ring 131 is movably provided on its outside. The connecting section 1322 can be used to enable the arc segment 1321 to be installed between the two mounting rings 131. After the positioning assembly 13 is inserted into the laparoscope rod, the plurality of arc segments 1321 are compressed so that the plurality of arc segments 1321 can realize adaptive deformation according to the inner diameter of the laparoscope rod, and thus can be fitted in laparoscope rods of different sizes. At the same time, the hose body 111 inside the plurality of arc segments 1321 can be centered. At this time, the hose body 111 will not contact the inner wall of the laparoscope rod, and thus an effective cleaning effect can be achieved when the water flows out through the flushing hole 112.
