AI Technical Summary

Technical Problem

Existing traction devices for digestive endoscopy have shortcomings in terms of clamping reliability and traction force control, which can easily lead to mucosal tissue slippage and loss of force control, increasing surgical risks.

Method used

A traction device for digestive endoscopy was designed. The clamping ends of the clamping arms are controlled to move closer and/or further apart via an operating panel. The device utilizes the cooperation of locking clips and linkage components to achieve stable clamping and controllable traction of mucosal tissue. The device includes a clamping cylinder, a wedge-shaped seat, linkage components, and locking clips.

Benefits of technology

It improves the clamping and fixation effect of mucosal tissue and the convenience of traction operation, ensures precise control of traction force and displacement, and reduces the risk of complications during surgery.

Abstract

The application belongs to the technical field of medical apparatus and discloses a traction device based on a digestive endoscope operation, which comprises a fixing seat, the fixing seat is connected with a central shaft and a fixing base, the outer side of the central shaft is sleeved with a clamping cylinder, the clamping cylinder is connected with a first linkage and a wedge-shaped seat, and the first linkage is connected with an operation plate; the outer side of the clamping cylinder is sleeved with a traction cylinder, the traction cylinder is connected with a traction base and a second linkage, the traction base is rotationally connected with a pair of clamping arms, the linkage ends of the pair of clamping arms are slidably abutted against the wedge-shaped inclined surface of the wedge-shaped seat, and the second linkage is connected with a locking clamping piece. The operation plate is used to control the clamping ends of the pair of clamping arms to approach each other and / or move away from each other, so as to realize the clamping and fixing of the mucosa tissue. The clamping force of the clamping arm is controllable, the clamping and fixing of the mucosa tissue is stable and reliable. The locking clamping piece is used to adjust the movement of the traction base through the clamping relationship with the fixing base and / or the first linkage, so as to realize the traction of the mucosa tissue.
