Gastrointestinal endoscopy minimal invasive scalpel device

Abstract

The invention discloses a gastrointestinal endoscopy minimal invasive scalpel device. The gastrointestinal endoscopy minimal invasive scalpel device comprises a first scissor type handle and a secondscissor type handle which is connected in a crossed and rotary mode with the first scissor type handle, wherein the second scissor type handle is fixedly connected with an insertion catheter, and oneend of the insertion catheter is provided with a scalpel module. According to the gastrointestinal endoscopy minimal invasive scalpel device, a second scalpel body rotates close to a first scalpel body to excise lesions, and meanwhile, the gastrointestinal endoscopy minimal invasive scalpel device is relatively simple in surgical operation and can conveniently and rapidly excise the lesions and improve the surgical operation efficiency; during the process that the scalpel module at the end of the insertion catheter, an operator can control to close the first scalpel body and the second scalpelbody to prevent the first scalpel body and the second scalpel body from scratching other normal tissues in vivo of a patient, so that surgical safety can be improved, and further in vivo injury to the patient can be reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a digestive endoscope minimally invasive scalpel device. Background technique [0002] With the development of digestive endoscopic technology, the indications for minimally invasive treatment under endoscopy continue to expand, and related minimally invasive techniques such as EMR, ESD, POEM, etc. continue to emerge and develop. ESD surgery is currently an important method for the treatment of early gastrointestinal tumors and precancerous lesions. It shows great advantages due to its small trauma, maintaining organ function, and quick postoperative recovery. However, its technical requirements are high, and complications such as perforation are prone to occur, which greatly limits its wide application. The existing HOOK knife and IT knife are important tools to promote the development of this technology, but there are still some deficiencies in actual work, such as the knife...

Problems solved by technology

However, its technical requirements are high, and it is prone to complications such as perforation, which greatly limits its wide application.

The existing HOOK knife and IT knife are important tools to promote the development of this technology, but there are still some deficiencies in actual work, such as the knife body and the plane of the surgical field are at a relatively large (approximately vertical) angle, and the electric cutting action is easy Deep cutting or even perforation makes the operation very difficult and the work efficiency of the operation is very low; and in the prior art, when the knife body is inserted into the lesion under the endoscope, it is easy to scratch other normal tissues in the patient's body, which is safe. lower, for this reason, the present invention proposes a minimally invasive scalpel device for digestive endoscopy
