AI Technical Summary
During digestive endoscopy, the need to frequently change different instruments leads to cumbersome procedures, long operating times, high physical exertion for medical staff, and a heavy burden on patients.
Design a multifunctional snare device that integrates a snare assembly, a cutting knife assembly, a sheath tube, an operating tube, and a handle. Combined with a flexible conductive wire and a conductive tube, it integrates multiple treatment functions, including snare, cutting, water injection, and ventilation/watering functions. Flexible switching of the device is achieved through sliding clasps and limiting buckles.
This allows for the elimination of frequent instrument changes during digestive endoscopy, simplifying procedures, reducing treatment time, lowering the workload of medical staff, and alleviating the burden on patients.

Abstract
Claims
1. A multi-functional snare, characterized by, It includes a snare assembly, a cutting knife assembly, a sheath tube, an operating tube, and a handle. The operating tube contains a hollow connecting rod. One end of the sheath tube is equipped with the snare assembly and the cutting knife assembly, and the other end is connected to the operating tube. The operating tube is equipped with a handle. The handle includes a sliding retaining ring, a fixed retaining ring, and a tail connecting tube. The sliding retaining ring is slidably fitted onto the operating tube and has a conductive connector. One end of the loop assembly passes through the sheath tube and is connected to a connecting rod. A metal block is provided in the middle of the connecting rod, and a sealing gasket is provided at the other end of the connecting rod. An opening is provided in the middle of the sealing gasket. A metal block is threaded to the bottom of the conductive connector. A fixed retaining ring is fixedly provided on the side wall of one end of the operating tube, and the tail connecting tube is connected through one end of the operating tube.
2. The multi-functional snare according to claim 1, wherein, The snare assembly includes a ceramic head, a flexible conductive wire, and a flexible conductive tube. One end of the flexible conductive wire and the flexible conductive tube is fixedly connected to the ceramic head, and the other end of the flexible conductive wire is fixed to the flexible conductive tube by a snap-fit method. The flexible conductive tube passes through the sheath tube and is connected to the inner cavity of the connecting rod.
3. The multi-functional snare according to claim 2, wherein, The cross-sectional diameter of the ceramic head and tail is smaller than the inner diameter of the sheath tube, while the cross-sectional diameter of the ceramic head at the front is larger than the inner diameter of the sheath tube.
