The top outer wall of the funnel 31 is in annular contact and fixed with the inner wall of the container 3 to prevent water leakage between the outer periphery of the funnel 31 and the inner wall of the container 3. The bottom water outlet of the funnel 31 is located on the central axis of the container 3. The equipment body 1 is slidably connected with a pull-out member 4. The pull-out member 4 includes a fixedly connected connecting rod 40, a wall plate 1 41, a wall plate 2 42, and a filter cartridge 43. The side wall of the equipment body 1 is provided with a wall hole 11 corresponding to the wall plate 1 41. The wall hole 11 is a countersunk hole, which can position the wall plate 1 41 to prevent the wall plate 1 41 from entering the interior of the equipment body 1. A handle is provided on the outer surface of the wall plate 1 41. The side wall of the container 3 is provided with a second wall hole 32 corresponding to the second wall plate 42. A sealing ring 44 is fixed around the outer wall of the second wall plate 42. The sealing ring 44 prevents water leakage between the second wall plate 42 and the inner wall of the second wall hole 32, and the sealing ring 44 increases the friction force to prevent the pull-out member 4 from moving spontaneously. The filter cartridge 43 is located in the container 3 and connected to the lower end of the funnel 31. The filter cartridge 43 is made of a filter screen. The top end of the filter cartridge 43 is open. A filter membrane can be placed in the filter cartridge 43. Placing the filter membrane can improve the filtering effect, and not placing the filter membrane can improve the filtering speed.

[0036] Reference Figure 4 It should be noted that the container 3 is made of transparent material, and a transparent plate 12 is provided on one side wall of the equipment body 1. The transparent plate 12 and the wall plate 41 are located on two adjacent side walls of the equipment body 1. The transparent plate 12 corresponds to the position of the container 3, so the personnel can observe the gravel on the funnel 31 through the transparent plate 12 and the container 3, which is convenient for observing the number and size of gravel extracted each time. The angle between the top surface of the funnel 31 and the horizontal plane is not greater than 30 degrees. After the liquid flows away, the gravel can remain on the funnel 31, which is convenient for the staff to observe immediately.

[0037] Reference Figure 2 A water pump 23 is provided on the water outlet pipe 22. The end of the water outlet pipe 22 away from the handheld device 2 is connected to the inner top of the container 3 and is located above the funnel 31. The suction force of the water pump 23 acts on the surgical site through the handheld device 2. The water pump 23 is used to extract the liquid in the surgical site and transport the liquid and the gravel to the funnel 31 together.

[0038] The end of the water inlet pipe 21 away from the handheld device 2 is connected to the bottom of the side wall of the container 3. The water inlet pipe 21 is provided with a water pump 24 and a filter element 25. Clean liquid is input into the handheld device 2 through the water pump 24, and the liquid is transported to the surgical site through the handheld device 2 to replenish the extracted liquid space.

After the water pump 3 52 is started, the water pump 3 52 replenishes clean liquid into the container 3 to make up for the consumption of the liquid in the container 3. At the same time, the gravel and dirt on the top surface of the funnel 31 are washed through the shower nozzle 53 to clean the top surface of the funnel 31.

[0040] A ventilation tube 33 is provided on the top of the container 3, and the air pressure inside and outside the container 3 is balanced through the ventilation tube 33, so that the air pressure in the container 3 is maintained at a normal pressure state.

[0041] A sewage tank 6 is also provided in the equipment body 1, and an overflow pipe 61 is connected to the container 3. The height of the overflow pipe 61 is lower than the filter cartridge 43, and the sewage tank 6 is connected to the outer end of the overflow pipe 61. A sleeve 34 is fixed to the inner bottom wall of the container 3. The sleeve 34 is located directly below the filter cartridge 43. The inner diameter of the sleeve 34 is larger than the filter cartridge 43, ensuring that the sewage dripping from the filter cartridge 43 enters the sleeve 34. The end of the overflow pipe 61 located in the container 3 is located in the sleeve 34, and the top of the sleeve 34 is higher than the overflow pipe 61.

[0042] The overflow pipe 61 is used to ensure that the highest water level in the container 3 is not higher than the overflow pipe 61. The water dripping from the filter cartridge 43 is relatively turbid and may also be mixed with colloids. The turbid water can enter the sewage tank 6 through the overflow pipe 61, thereby improving the water quality in the container 3. It should be noted that the liquid input into the container 3 must be greater than the liquid output, so that the overflow pipe 61 will overflow spontaneously. The additional liquid input into the circulation system is input through the water supply pipe 51.

[0043] The side wall of the sleeve 1 34 is provided with a plurality of water holes 35, and the inner bottom wall of the container 3 is fixed with a sleeve 2 36, which is located outside the sleeve 1 34, and an annular passage is formed between the sleeve 2 36 and the sleeve 1 34, and the upper end of the sleeve 2 36 is higher than the water holes 35. Through the cooperation of the sleeve 1 34 and the sleeve 2 36, the distance for the liquid to enter the water inlet pipe 21 is extended, the disturbance of the liquid near the inner wall of the container 3 by the water splash is reduced, and the air bubbles are prevented from entering the water inlet pipe 21.

[0044] The implementation principle of a laser lithotripsy therapeutic device in an embodiment of the present application is: laser lithotripsy is performed on the surgical site through a handheld device 2, the liquid and lithotripsy at the surgical site are transported to a container 3 through a water pump 1 23, clean liquid is added to the surgical site through a water pump 24, and new liquid is input into the container 3 through a water pump 3 52. The start and stop of the three water pumps are controlled by switches respectively.

[0045] After the liquid on the funnel 31 flows away, the gravel can remain on the funnel 31, which is convenient for the staff to immediately observe the number and size of the gravel extracted each time. When cleaning is needed, the water pump 3 52 is started to spray liquid on the funnel 31 for washing. The gravel is filtered in the filter cartridge 43, and the liquid dripping from the bottom of the filter cartridge 43 is relatively turbid. Most of the turbid liquid can be discharged through the overflow pipe 61, thereby improving the liquid cleanliness of the circulation system, and the filter element 25 can be used for a long time, reducing the frequency of replacement.

[0046] When the filter cartridge 43 needs to be taken out, the entire pull-out member 4 can be pulled out through the wall plate 41, and then the filter cartridge 43 can be turned over and tipped, which is also convenient for replacing the filter membrane.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
