[0017] The lavage device for laparoscopic surgery provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides an irrigation device for laparoscopic surgery, comprising two piston cylinders, two first pipes, two second pipes, two tee connectors, two third pipes, two container tanks, an irrigation tube, a suction tube, a two-position three-way solenoid valve, and a piston. One end of each of the two first pipes is connected to one of the two piston cylinders, and both first pipes are used to transport a medium. One end of each of the two second pipes is also connected to one of the two piston cylinders, and both second pipes are also used to transport a medium. One port of each of the two tee connectors is connected to the other end of each of the two first pipes, and the other ports of each of the two tee connectors are connected to the other ends of each of the two second pipes. Both third connectors are used for merging or splitting flow. One end of each of the two third pipes is connected to another port of each of the two tee connectors, and both third pipes are also used to transport a medium. The two container tanks are connected to the other ends of each of the two third pipes, and each container tank is used to hold a solution. One end of the irrigation tube is inserted into one of the two container tanks, and the container connected to the irrigation tube contains irrigation water, with the end of the irrigation tube inserted into the container immersed in the irrigation water. One end of a suction tube is inserted into the other of two containers. The container connected to the suction tube contains a disinfectant solution, and the end of the suction tube inserted into the container is positioned above the disinfectant solution. Two-position three-way solenoid valves are installed on two third pipes, allowing the two third pipes to connect to the two containers or to the outside environment. Four one-way valves are installed on two first pipes and two second pipes, controlling the flow direction of the medium within the pipes; the flow directions in the two first pipes and two second pipes are opposite. Pistons are installed inside two piston cylinders to generate gas pressure. Under external force, the two pistons slide alternately back and forth relative to the two piston cylinders.

[0019] In operation, controlling the two 2-position 3-way solenoid valves connects the two third pipes to the two containers. Driven by external force, the two pistons alternately move downwards, reducing the pressure inside the piston cylinder. The two first pipes and their corresponding third pipes then draw in the gas inside the container holding the disinfectant solution, creating a negative pressure at the suction pipe port, drawing the solution into the container. Simultaneously, the two pistons alternately move upwards, expelling the gas inside the piston cylinder. This expelled gas then exits through the two second pipes and their corresponding third pipes into the container holding the cleaning solution. Under pressure, the cleaning solution is discharged through the rinsing pipe for rinsing. Therefore, suction and rinsing can be performed simultaneously. Furthermore, controlling the two 2-position 3-way solenoid valves connects one of the two third pipes to the container and the other to the outside, allowing the two third pipes to draw in the gas inside the container holding the disinfectant solution and discharge the expelled gas to the outside, thus enabling individual suction. Alternatively, two third pipes can be used to deliver the extruded gas into a container holding the cleaning solution and to draw in gas from the outside, thus performing a separate flush.

[0036] Combination Figures 1 to 4 As shown, this disclosure provides an irrigation device for laparoscopic surgery, including two piston cylinders 1, two first pipes 2, two second pipes 3, two tee connectors 4, two third pipes 5, two container tanks 6, an irrigation tube 7, a suction tube 8, a two-position three-way solenoid valve 9, four one-way valves, and a piston 10. One end of each of the two first pipes 2 is connected to one of the two piston cylinders 1, and both first pipes 2 are used to transport media. One end of each of the two second pipes 3 is also connected to one of the two piston cylinders 1, and both second pipes 3 are also used to transport media. One port of each of the two tee connectors 4 is connected to the other end of each of the two first pipes 2, and the other ports of each of the two tee connectors 4 are connected to the other ends of each of the two second pipes 3. Both third connectors are used for merging or splitting flow. One end of each of the two third pipes 5 is connected to the other port of each of the two tee connectors 4, and both third pipes 5 are also used to transport media. The two container tanks 6 are connected to the other ends of each of the two third pipes 5, and both container tanks 6 are used to hold solutions. One end of the flushing pipe 7 is inserted into one of the two container tanks 6. The container tank 6 connected to the flushing pipe 7 contains flushing water, and the end of the flushing pipe 7 inserted into the container tank 6 is immersed in the flushing water. One end of the suction pipe 8 is inserted into the other of the two container tanks 6. The container tank 6 connected to the suction pipe 8 contains disinfectant solution, and the end of the suction pipe 8 inserted into the container tank 6 is above the disinfectant solution. Two-position three-way solenoid valves 9 are respectively installed on two third pipes 5, used to connect the two third pipes 5 to the two container tanks 6 or to the outside. Four one-way valves are respectively installed on two first pipes 2 and two second pipes 3, used to control the flow direction of the medium in the pipes. The flow direction of the medium in the two first pipes 2 and the two second pipes 3 is opposite. Pistons 10 are respectively installed inside two piston cylinders 1, used to generate gas pressure. Under the drive of external force, the two pistons 10 slide alternately back and forth relative to the two piston cylinders 1.

[0037] This embodiment of the laparoscopic surgical irrigation device controls two two-position three-way solenoid valves 9 to connect two third pipes 5 to two receiving containers 6. Driven by external force, when the two pistons 10 alternately move downwards, the pressure inside the piston cylinder 1 decreases. Then, the two first pipes 2 and the corresponding third pipes 5 draw in the gas inside the receiving container 6 containing disinfectant solution, creating a negative pressure at the port of the suction pipe 8, which draws the solution into the receiving container 6. Simultaneously, the two pistons 10 alternately move upwards, expelling the gas inside the piston cylinder 1. The expelled gas is then discharged through the two second pipes 3 and the corresponding third pipes 5 into the receiving container 6 containing cleaning solution. Under pressure, the cleaning solution is discharged through the irrigation pipe 7 for rinsing. Therefore, suction and rinsing can be completed simultaneously. Furthermore, by controlling the operation of two two-position three-way solenoid valves 9, one of the two third pipes 5 is connected to the container 6, and the other is connected to the outside. The two third pipes 5 can then draw in the gas inside the container 6 containing the disinfectant solution and discharge the squeezed-out gas to the outside, thus performing liquid suction independently. Alternatively, the two third pipes 5 can transport the squeezed-out gas into the container 6 containing the cleaning solution and draw in gas from the outside, thus performing rinsing independently.

[0038] Optionally, combined Figure 1 As shown, the assembly also includes a housing 11, two piston rods 12, two bending plates 13, a dual-axis motor 14, two cams 15, and two connecting rods 16. Both piston cylinders 1 are mounted on the top wall of the housing 11, with their open ends located inside the housing 11 and their closed ends located outside. The two piston rods 12 are respectively mounted on the two pistons 10, both located inside the housing 11, and are used to drive the movement of the two pistons 10. The two bending plates 13 are respectively connected to the two piston rods 12 and are slidably mounted inside the housing 11, allowing them to slide relative to the housing 11 and thus drive the movement of the two piston rods 12. The dual-axis motor 14 is mounted on the bottom wall of the housing 11, located inside the housing 11, and provides driving force to achieve the rotational motion function. The two cams 15 are respectively mounted on the two rotating ends of the dual-axis motor 14, and rotate under the drive of the two rotating ends of the dual-axis motor 14. Two connecting rods 16 are rotatably mounted between two cams 15 and the two rotating ends of the dual-axis motor 14, respectively, and can rotate relative to the two cams 15 and the two rotating ends of the dual-axis motor 14. The sliding direction of the two bent plates 13 relative to the housing 11 is the same as the sliding direction of the two pistons 10 relative to the two piston cylinders 1.

[0039] In this embodiment, controlling the dual-axis motor 14 drives the two cams 15 to rotate. Then, under the pull or push of the two connecting rods 16, the two bending plates 13 slide back and forth relative to the housing 11. This, in turn, drives the two piston rods 12 to move up and down reciprocally, ultimately causing the two pistons 10 to move up and down alternately. That is, while one piston 10 moves upward, the other piston 10 moves downward, and vice versa. This allows for continuous air intake and exhaust, ultimately enabling continuous rinsing and liquid suction.

[0040] Optionally, combined Figure 1 As shown, it also includes two guide rails 17 and two sliders 18. Both guide rails 17 are mounted on the inner wall of the housing 11, and are used to support the sliding sliders 18. The two sliders 18 are respectively mounted on the two guide rails 17 and are respectively connected to two bending plates 13. The two sliders 18 move synchronously with the two bending plates 13.

[0041] In this embodiment, the two guide rails 17 and the two sliders 18 serve as guides and supports, allowing the two bent plates 13 to slide inside the housing 11. During use, controlling the dual-axis motor 14 drives the two cams 15 to rotate. Then, under the pulling or pushing of the two connecting rods 16, and with the guiding and supporting action of the two guide rails 17 and the two blocks, the two bent plates 13 can reciprocate up and down. This, in turn, drives the two piston rods 12 to reciprocate up and down, ultimately driving the two pistons 10 to alternately reciprocate up and down.

[0042] Optionally, combined Figure 1 and Figure 2 As shown, it also includes four limiting pins. The four limiting pins are located at both ends of the two guide rails 17 and are all installed on the inner wall of the housing 11.

[0043] In this embodiment, all four limiting pins are used to limit the movement of the two sliders 18 from the two guide rails 17.

[0044] Optionally, combined Figure 1 As shown, it also includes two first fixing rings 19 and two second fixing rings 20. The two first fixing rings 19 are respectively fitted onto the outer walls of the two piston cylinders 1, both located outside the housing 11, and both abut against the outer wall of the housing 11. The two second fixing rings 20 are respectively fitted onto the outer walls of the two piston cylinders 1, both located inside the housing 11, and both abut against the inner wall of the housing 11.

[0045] In this embodiment of the disclosure, two first fixing rings 19 and two second fixing rings 20 are used to axially fix the two piston cylinders 1 to determine the relative positions of the housing 11 and the two piston cylinders 1.

[0046] Optionally, combined Figure 1 and Figure 3 As shown, it also includes two supports 21. Both supports 21 are installed on the outer wall of the housing 11, and the two containers 6 are placed on the two supports 21 respectively.

[0047] In this embodiment of the disclosure, two supports 21 are used to support the placement of two containers 6 so as to facilitate the transfer of the entire device together.

[0048] Optionally, combined Figure 1 and Figure 3 As shown, it also includes four casters. The four casters are respectively installed at the four corners of the bottom surface of the housing 11, and are used to abut against the ground.

[0049] In this embodiment of the disclosure, all four corner casters are used to abut against the ground to provide a rolling function, thereby facilitating the movement of the entire device.

[0050] Optionally, combined Figure 1 and Figure 3 As shown, it also includes multiple handles. The multiple handles are evenly installed on the outer wall of the housing 11, all for gripping.

[0051] In this embodiment of the disclosure, multiple handles are used for gripping, so as to facilitate manual movement of the entire device.

[0052] Optionally, combined Figure 4 As shown, it also includes a rinsing gun 22. The rinsing gun 22 includes a rinsing channel and a suction channel. The other end of the rinsing tube 7 is connected to the rinsing channel, and the other end of the suction tube 8 is connected to the suction channel.

[0053] In this embodiment, the other end of the flushing tube 7 is connected to the flushing channel to discharge the flushing solution. The other end of the suction tube 8 is connected to the suction channel to draw up the solution. The design of the flushing gun 22 makes it easy to hold and point at the flushing area and the washing solution.
