Multifunctional traction device for minimally invasive treatment on gastrointestinal tumors

Abstract

The invention relates to a multifunctional traction device for minimally invasive treatment on gastrointestinal tumors. The multifunctional traction device comprises a fixed base, a first supporting plate, a second supporting plate, a handle and a roller; the first supporting plate and the second supporting plate are fixed on the fixed base and are provided with mounting holes; a section of rolling shaft is arranged at the central axis of each of the two ends of the roller, and the rolling shafts penetrate through the mounting holes and enable the roller to have the degree of freedom of rotating around the axis under the support of the mounting holes; and the rolling shaft at one end of the roller is connected with the handle, and the handle drives the rolling shaft to rotate, so that the roller rotates accordingly. The multifunctional traction device can replace manpower to pull a pull wire, the pull wire is wound on the roller, when oblique teeth on two discs are meshed with corresponding clamping teeth, the two discs can only rotate in one direction, and when a focus needs to be pulled up, the clamping teeth can limit wheel discs to rotate in the other direction after the pull wire is adjusted to a proper length, so that the length of the nylon wire is fixed, and tension is generated to continuously pull the focus.

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
