Abstract

The invention discloses a multifunctional incision knife. The incision knife comprises an O-shaped knife body and an I-shaped knife body, the rear end of the tubular O-shaped knife body is fixedly connected with the far end of a liquid injection pipe through a liquid injection connecting pipe, the rod-shaped I-shaped knife body is arranged in the O-shaped knife body in a penetrating mode, a gap is reserved between the I-shaped knife body and the inner pipe wall of the O-shaped knife body, and the rear end of the I-shaped knife body is fixedly connected with the far end of the conductive wire through a conductive connecting pipe; and the conductive connecting tube is provided with a first channel through which liquid can flow into a tube hole of the O-shaped knife body, the conductive ring is provided with a second channel through which the liquid can flow out of the tube hole of the O-shaped knife body, and the liquid injection connecting tube is arranged in a far-end tube opening of an outer sheath tube and is provided with a through hole which is communicated with the outside of the far-end tube opening of the outer sheath tube from the interior of a tube hole of the liquid injection connecting tube. According to the scheme, the functions of I-knife stripping, O-knife electrocoagulation, intraoperative liquid supplementing and injection, knife head and bleeding point flushing and the like are integrated, and the electric resection and electrocoagulation performance is optimized.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a multifunctional incision knife. Background technique [0002] Endoscopic submucosal dissection (Endoscopic submucosal dissection, ESD) is a new treatment method that has emerged in recent years. Complete resection avoids the pain of open surgery and the removal of organs. Endoscopic mucosal dissection is a new treatment method that has emerged in recent years, and it is also a technology with good clinical application prospects. It allows more early-stage gastrointestinal cancers to be completely resected under endoscopy at one time, eliminating the need for laparotomy. For the pain and removal of organs, the important surgical tool for endoscopic mucosal dissection is the mucosal incision knife. [0003] Common incision knives for early cancer peeling on the market include needle knife, IT knife (with ceramic head), hook knife, triangular knife, Flush knife (with...
