Adjustable hook type operation expansion device

Abstract

The invention discloses an adjustable hook type operation expansion device which comprises a fixing device and metal hooks, wherein the fixing device comprises two fixing plates; end parts of the twofixing plates are rotationally connected through hinges; and the metal hooks comprise hook fixing parts at rear ends and hook head mounting parts at front ends. The adjustable hook type operation expansion device is simple in structure, smart in design, simple and convenient in adjusting angle positions and hook lengths, convenient for an operation doctor to adjust the angles of different components of the operation hooks according to surgery field requirements of operation, capable of effectively relieving physical consumption caused by the situation that an assistant needs to keep special position hooking for a long time, and beneficial to smooth operation, in addition, the device can be adjusted according to demands, and the phenomenon that operation of doctors is obstructed by hooks iseffectively prevented.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an adjustable hook-type surgical expansion device. Background technique [0002] Objective: During surgery, a good exposure of the surgical field is a prerequisite for successfully completing various operations. In various surgical operations, surgical retractors are widely used, which fully exposes the surgical field, facilitates surgical operations, speeds up the progress of the operation, and completes the operation smoothly. At present, the exposure of most open operations is done with the help of surgical retractors. The following types of surgical retractors are commonly used clinically: Ordinary "L"-shaped or "S"-shaped retractors: can be adjusted according to the actual situation of various operations The pulling force and the direction of the hook are easy to operate and flexible. However, this type of retractor must be continuously pulled by manpower to expose the su...

AI Technical Summary

Problems solved by technology

However, this kind of retractor must be continuously pulled by manpower to reveal the surgical field, which makes the retractor easy to fatigue; at the same time, because the retractor often has poor standing and limited vision, it is very easy to have unstable pulling and angle deviation. Problems are more likely to occur in deep surgery or obese patients, which affects exposure and makes surgery difficult

Two-wing or three-leaf automatic retractor in the abdominal cavity: its application range is limited, and the exposure of the deep surgical field is not good

Ring-shaped automatic retractor: four fixed points are used as the force point to pull, and the pull force point cannot be adjusted at any angle. It still cannot achieve a good exposure of the surgical field, and it is time-consuming to install, and it is inconvenient to adjust during the operation.
