Abstract

The invention discloses a polyp resection apparatus. The polyp resection apparatus is additionally provided with an injection function component on the basis of an incision function component, the process of injecting and raising the polyp is realized before a tissue is sheathed with a loop of the incision function component, the tissue is rapidly and accurately sheathed, so that the operation reliability of the polyp resection apparatus is effectively improved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and relates to a polypectomy instrument, which is used in non-vascular cavities such as digestive tracts. Background technique [0002] The polypectomy instrument is mainly used for excision of various polyps and redundant tissues under the endoscope with high-frequency electricity. [0003] Among them, the common polypectomy device is a snare, specifically a device that uses a nylon rod to tighten a slippery knot that has been previously tied with an absorbable thread or a synthetic thread to ligate blood vessels, polyps, or other pipeline structures. It is easy to operate. Has been used in a variety of laparoscopic abdominal surgery. [0004] However, during the operation of conventional resection instruments, tissue slippage will occur during the process of enclosing the diseased tissue with the ferrule, which requires multiple ferrules, and the operation time is long, which affec...
