Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically relates to a calculus irrigation device. Background Art

[0002] Kidney stones are a common problem in the urinary system. In some clinical situations, the stones can be very large, especially the cast stones located in the renal pelvis. Removing such large stones takes a long time. Usually, forceps are used to remove larger broken stones, while smaller broken stones are washed. Existing washing devices generally consist of a water pump, a catheter, and a washing nozzle. However, traditional washing devices need to adjust the water pressure by adjusting the output power of the water pump. Since the distance from the water pump to the spray holes of the washing nozzle is relatively far, after adjustment, the change is not timely, which affects the effect of the washing operation. Therefore, we propose a calculus irrigation device. Content of the Utility Model

[0003] One technical problem to be solved by this application is: how to design a calculus irrigation device that can adjust the irrigation pressure in a timely and efficient manner.

[0004] To solve the above technical problem, the embodiment of this application provides a calculus irrigation device, which includes a nozzle and a catheter conductively connected to the nozzle. The catheter is connected to a water pump, and further includes:

[0005] A return pipe, which is arranged on the nozzle and conductively connected to it, and one end of the return pipe is conductively connected to the water storage device of the water pump for returning the irrigation liquid;

[0006] A valve assembly, which is arranged on the nozzle to gradually close the return pipe;

[0007] A touch switch, which is arranged on the nozzle to control the valve assembly, and a plurality of spray holes are evenly arranged at equal distances at one end of the catheter;

[0008] A plugging assembly, which is arranged in the nozzle. When the touch switch is triggered, the return pipe is completely opened by using the valve assembly, and at the same time, the spray holes are plugged by using the plugging assembly.

[0009] In some embodiments, the valve assembly includes a hollow tube arranged in the nozzle. One end of the return pipe is located in the hollow tube and fixed to it. A sliding cylinder is slidably connected in the hollow tube. A through hole communicating with the hollow tube is opened at one end of the sliding cylinder, and a water leakage hole communicating with the through hole is opened on one side of the sliding cylinder. The sliding cylinder is slid to gradually block the water leakage hole by the hollow tube.

[0010] In some embodiments, the touch switch includes a slider fixedly connected to the sliding cylinder. A guiding groove is opened on the nozzle. One end of the slider passes through the guiding groove to push the slider to drive the sliding cylinder to move.

[0011] In some embodiments, the plugging assembly includes an arc-shaped plate 1 disposed in the nozzle, and a plurality of water outlet grooves aligned with the plurality of spray holes are evenly and equidistantly formed on the arc-shaped plate 1, and the arc-shaped plate 1 is rotated so that the water outlet grooves are staggered with the spray holes;

[0012] An arc plate 2 is slidably connected inside the nozzle, and the arc plate 2 is connected to the arc plate 1, and a guide rail is provided on the arc plate 2. A push plate is fixedly connected to one end of the sliding cylinder, and a convex is provided at one end of the push plate, and the convex is connected to the guide rail to push the sliding cylinder, thereby driving the convex to push the guide rail to drive the arc plate 1 to rotate.

[0013] In some embodiments, the guide rail member includes a straight sliding groove opened on the arc plate one, one end of the round protrusion is located in the straight sliding groove, and the arc plate one is provided with a spiral groove connected to the straight sliding groove. The round protrusion is pushed to push the spiral groove to rotate the arc plate one.

[0014] In some embodiments, a return spring is disposed in the hollow tube, and both ends of the return spring are respectively fixed to the hollow tube and the sliding cylinder to push the sliding cylinder. At the same time, the return spring is compressed and contracted to provide it with self-restoring ability.

[0015] The utility model has at least the following beneficial effects:

[0016] Medical staff hold the nozzle and use their thumb to move the slider, so as to gradually close the return pipe with the valve assembly. During this process, the water flow through the nozzle hole gradually increases, thereby achieving the effect of gradually increasing the nozzle pressure. It is relatively simple and convenient, and the adjustment is more timely and flexible.

[0017] At the same time, when the medical staff fully opens the reflux pipe, the nozzle hole is blocked by the blocking component, so that the flushing operation can be stopped without turning off the water pump. This is relatively simple and convenient, more suitable for medical conditions that require frequent closing and opening of the nozzle, and more flexible. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating circular plate is slidably connected to the inner wall of the nozzle 1. A guide rail member 41 is arranged on the second arc-shaped plate 39. One end of the sliding cylinder 32 is fixedly connected with a push plate 42. One end of the push plate 42 is fixedly connected with a circular convex 43. The circular convex 43 is connected with the guide rail member 41.
