Description

Technical Field

[0001] This utility model relates to the field of urinary stone removal technology, and in particular to a urinary stone removal device. Background Technology

[0002] Laparoscopic ureteroscopic lithotripsy involves inserting a laparoscope and ureteroscope (also known as a urethroscope) through a small incision in the abdomen to directly observe and manipulate stones in the ureter or renal pelvis. The doctor then uses forceps or a laser to break down or remove the stones as a whole.

[0003] A urinary stone removal device disclosed in publication number CN219516446U includes a guide section. One end of the guide section has a handle fixedly mounted on it, and the other end has symmetrically movably arranged clamping pieces. Symmetrically arranged wire holes are provided within the guide section, and a steel wire is movably installed within each hole. One end of the steel wire is fixedly connected to the clamping piece, and the other end extends into the handle and connects to sliders slidably disposed on opposite side walls of the handle. This urinary stone removal device allows for manual control of a sliding buckle moving within a sliding groove. The buckle drives the slider, which in turn pulls the steel wire. The steel wire, through a pulley, changes the direction of force, causing the clamping pieces to move to both sides, separating them. A first spring on each clamping piece applies a pushing force, allowing the two clamping pieces to come together, thus providing clamping force. The bidirectional engagement of the two clamping pieces results in a larger clamping radius, making it easier to remove larger stones.

[0004] Although the aforementioned patent achieves a larger clamping radius due to the bidirectional engagement of the two clamping plates, making it easier to remove larger stones, the device still requires removing stones one by one, increasing the burden on medical staff.

[0005] Therefore, it is necessary to invent a urinary stone removal device to solve the above problems. Utility Model Content

[0012] As a further embodiment of this utility model, the spring is located outside the moving rod and the cylinder, and an anti-slip sleeve is fitted onto the outside of the handle, which serves to prevent the handle from slipping.

[0013] As a further embodiment of this utility model, a sliding hole is provided inside the tube body, and the sliding hole is the same size as the connecting column, so as to facilitate the sliding of the connecting column inside the tube body.

[0014] As a further embodiment of this utility model, the upper and lower clamping plates are provided with grooves inside, and the grooves are of the same size to facilitate the placement of the connecting rod.

[0016] (III) Beneficial Effects

[0017] This utility model provides a urinary stone removal device, which has the following beneficial effects:

[0018] 1. This urinary stone removal device, through the adjustment mechanism, upper clamp, lower clamp, and collection chamber, allows for the following operation: pulling the connecting column outward during clamping moves the square block, which in turn rotates the rotating rod. The rotating rod then causes the upper and lower clamps to close and clamp the stone. During removal, smaller stones can be clamped into the collection chamber of the lower clamp first, avoiding the need for doctors to manually remove stones one by one and providing a larger clamping radius for easier stone removal, thus improving the efficiency of stone removal.

[0019] 2. This urinary stone removal device, through the setting of a semi-circular sleeve and a stretching mechanism, allows medical staff to hold the semi-circular sleeve and pull the handle during clamping. The handle moves the connecting column to clamp the stone. During clamping or removal, medical staff only need to hold the semi-circular sleeve and pull the handle left and right to complete the stone removal, which is easy to operate.
