Electrotome, high-frequency electrotome and connecting process of electrotome in high-frequency electrotome

Abstract

The invention provides an electrotome, a high-frequency electrotome and a connecting process of the electrotome in the high-frequency electrotome, the high-frequency electrotome comprises a handle assembly, an outer sheath pipe assembly, a traction assembly and the electrotome, the electrotome contains a tungsten material, and a knife body of the electrotome is arranged at one end of the outer sheath pipe assembly in a penetrating mode; the other end of the outer sheath pipe assembly is connected with the handle assembly; the traction assembly is arranged in the outer sheath pipe assembly in apenetrating mode and comprises a first connecting pipe, a soft wire, a second connecting pipe, a rotating shaft and a catheter which are connected in sequence, the soft wire is made of stainless steel materials or nickel-titanium wire materials, and the end of the soft wire and the knife body of the electrotome are both fixed in the first connecting pipe; and the catheter is connected with an electrode arranged in the handle assembly. According to the invention, the phenomena of smoke generation and mucous film tissue knife sticking during cutting are reduced.

Description

technical field [0001] The invention relates to the technical field of high-frequency electric knife, in particular to an electric knife, a high-frequency electric knife and a connection process of the electric knife in the high-frequency electric knife. Background technique [0002] Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is a new treatment method that has emerged in recent years, and it is also a technology with promising clinical application prospects. Resection, eliminating the pain of open surgery and the removal of organs. Compared with laparotomy and previous endoscopic treatment methods such as EMR (Endoscopic Mucosal Resec-tion, endoscopic mucosal resection), ESD has less trauma, and patients can receive multiple treatments for multiple parts, allowing doctors to obtain complete histopathological specimens For analysis, the resection rate is over 96% for tumors with large area and irregular shape or with ulcers and scars, so as to r...
