Multifunctional snare for endoscopic surgery

Abstract

The multifunctional snare comprises a handle, an outer sheathing canal, an inner sheathing canal, an electric burning ferrule and a clamp, the handle is provided with a first sliding block and a second sliding block which can slide, the inner sheathing canal is inserted into the outer sheathing canal, the outer sheathing canal and the inner sheathing canal are both arranged on the handle, and the electric burning ferrule is inserted into the second sliding block. The clamp is arranged at the free end of the inner sheath tube, the electric burning ferrule is arranged outside the inner sheath tube in a sleeving mode, the first sliding block is connected with the clamp through a first control piece, the second sliding block is connected with the clamp through a second control piece, the first control piece is located in the inner sheath tube, and the second control piece is located in the second sheath tube. The second control piece is located between the outer sheath tube and the inner sheath tube. Medical staff can conveniently clamp a polyp to accurately place the electrocautery ferrule, so that the operation difficulty is reduced, and the treatment effect is effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional snare for endoscopic surgery. Background technique [0002] Gastroscopy is a routine medical examination method. It is inserted into the stomach with a thin, flexible tube. Doctors can directly observe the lesions of the esophagus, stomach and duodenum, and can also perform pathological biopsy and cell biopsy of suspicious lesions. To further confirm the diagnosis, it is the preferred method of examination for upper gastrointestinal lesions. At the same time, when doing gastroscopy, combined with other equipment, it can also be directly treated, for example: under the direct vision of gastroscope, high-frequency electric knife is used to remove polyps. During the actual operation, since the surface of the stomach is covered with folds, some polyps are easily blocked by the folds. In this case, the injection needle needs to be inserted into the folds...
