Polypus excising device

Abstract

The invention discloses a polypus excising device. The polypus excising device comprises a connecting rod body, one or more flexible electric conduction pieces movably penetrating through the connecting rod body, one or more electricity supplying devices, annulus parts delimited on the flexible electric conduction pieces, a plurality of hot excision pieces, one or more combined fixing pieces fixedto one ends departing from the connecting rod body, of the annulus parts, one or more receiving assemblies, one or more isolation assemblies arranged on the annulus parts in a coating manner, and a collecting device. Through the adoption of the structure, the collecting device is interlocked with the flexible electric conduction pieces, due to the effects of the combined fixing pieces, during collection, only the hot excision pieces on the annulus parts are mutually close, and excessive deformation of the receiving assemblies (such as bag nets) can be avoided, so that under the action of theelectricity supplying devices, the hot excision pieces are used for excising the polypus, and the stability of the receiving assemblies for receiving the polypus can be promoted.

Description

technical field [0001] The invention provides a polypectomy device, especially a polypectomy device that can easily remove polyps, stably accept polyps, and prolong the service life. Background technique [0002] For the treatment of benign or malignant tumors such as polyps growing on the esophagus, stomach, large intestine and other body cavities, with the development of endoscopic examination and the increase of early detection cases in recent years, endoscopic The cases of excision and sectioning of polyps and tumors also increased rapidly. In particular, endoscopic polypectomy is a low-infection treatment, so its application cases have expanded. With the increasing number of polyps and cancer cases in an aging society, this type of surgery and its related tools are also rapidly popularized. [0003] As far as polypectomy is concerned, in addition to endoscope and electric cautery, the commonly used tools are also used to increase the frequency of use of polyp removal t...

AI Technical Summary

Problems solved by technology

[0005]First, the electric knife and the extraction tool are set on a ring together. When the electric knife is energized and heated, the extraction tool often touches the electric knife and is heated damaged

[0006]Secondly, the cutting action of the electrosurgical knife is retracted inward to the handle through the traction of the rear-end copper wire or network cable, but it will also be taken out when retracting. tools together, resulting in deformation of the removal tool and increasing the probability of damage due to contact with the electric knife
