A multifunctional pulling device for minimally invasive treatment of gastrointestinal tumors

Abstract

The present invention claims a multifunctional stretching device for minimally invasive treatment of gastrointestinal tumors, which includes a fixed base, a first support plate, a second support plate, a handle and a roller; the first support plate and the second support plate are fixed on On the fixed base, the first support plate and the second support plate have installation holes; a section of roller shafts are respectively arranged at the central shafts at both ends of the roller, and the roller shafts pass through the installation holes, and the roller can have a winding shaft under the support of the installation holes. The degree of freedom of center rotation; the roller shaft at one end of the drum is connected to the handle, and the handle drives the roller shaft to rotate, thereby realizing the rotation of the drum. This device can replace manpower to pull the traction wire. The traction wire is wound on the drum. When the helical teeth on the two discs mesh with the corresponding latch teeth, they can only rotate in one direction. When the lesion is to be pulled up, After adjusting the traction wire to an appropriate length, the locking teeth will restrict the rotation of the wheel in the other direction, thereby fixing the length of the nylon wire and generating tension to continuously pull the lesion.

Description

technical field [0001] The invention relates to the field of stretching devices, in particular to a multifunctional stretching device for minimally invasive treatment of gastrointestinal tumors. Background technique [0002] Endoscopic mucosal resection refers to the operation of complete resection of the diseased mucosa under the endoscope. It is a treatment method developed by combining endoscopic polypectomy and endoscopic submucosal injection. It belongs to elective diagnosis or radical treatment. Operation. Surgery aims to diagnose and treat mucosal lesions by en bloc resection of part of the mucosa. During the operation, the lesion is resected with an electric knife. During the resection, it is difficult to apply the electric knife due to problems such as poor lifting of the lesion and small submucosa space. It is necessary to keep pulling the lesion by manually pulling the traction wire to drive the peeling clip. It is necessary to increase the allocation of medical...

Problems solved by technology

During the operation, the lesion is resected with an electric knife. During the resection, it is difficult to apply the electric knife due to problems such as poor lifting of the lesion and small submucosa space. It is necessary to keep pulling the lesion by manually pulling the traction wire to drive the peeling clip. It is necessary to increase the allocation of medical staff, and the operation often takes a long time, and the medical staff will be too tired to keep pulling for a long time, and there are problems such as difficulty in controlling the force
