An easy-to-detachable sternal closure fixer set

Abstract

The invention discloses a sternum closing fixer package easy to disassemble. The sternum closing fixer package comprises a sternum closing fixer and a disassembling tool used for disassembling the sternum closing fixer. The sternum closing fixer comprises a locking wheel, a male fixing piece and a female fixing pipe. The male fixing piece comprises an elastic plug and a first claw-shaped hook plate which is arranged at one end of the elastic plug and extends downwards. First inclined teeth inclined towards one end of the first claw-shaped hook plate are arranged on the two sides of the male fixing piece. The female fixing piece comprises a socket and a second claw-shaped hook plate which is arranged at the bottom of one end of the socket and extends downwards. The socket is provided with a slot matched with the elastic plug, and second inclined teeth inclined towards the second claw-shaped hook plate are arranged on the two sides of the slot. When the sternum closing fixer is disassembled, the distance between the male fixing piece and the female fixing piece is reduced through the disassembling tool, the meshing state of the first inclined teeth and the second inclined teeth is removed, and thus the sternum closing fixer can be effectively, easily, conveniently and quickly disassembled.

Description

technical field [0001] The invention relates to an easy-to-detachable sternum closure fixer set. Background technique [0002] Thoracotomy requires an incision of the entire sternum. At the end of the operation, the traditional method of closing the sternum is to bind the entire sternum up and down with steel wires. Tighten it so that the incised sternum is closed and fixed. There are following deficiencies in the traditional steel wire fixing sternum method: 1, it is difficult to grasp and unify the tightness of fixing. 2. Cutting of the sternum by the steel wire is easy to occur, resulting in splitting of the sternum and bringing adverse consequences. 3. It is difficult to wear steel wire. [0003] Based on this, the sternal closure fixer is gradually favored by more and more doctors. The current sternal closure fixation device has a male fixing part and a female fixing part. A locking groove is arranged on the male fixing part, and a rotatable locking wheel is arrange...

AI Technical Summary

Problems solved by technology

There are following deficiencies in the traditional steel wire fixation method for sternum: 1. It is difficult to grasp the tightness of fixation and unify

2. It is easy to cut the sternum by the steel wire, which will cause the sternum to crack and bring adverse consequences

3. It is difficult to wear steel wire

However, in practical application, it is found that because the sternum heals takes a long time, it may cause plastic deformation of the male fixation piece, and finally lead to the situation that the sternal closure fixation is difficult to remove
