Surgical suite for sternal closure fixation

Abstract

The invention discloses a surgical suite for sternal closure fixation. The surgical suite comprises a sternal closure fixator, an installation tool used for installing the sternal closure fixator and a removal tool used for removing the sternal closure fixator; the sternal closure fixator comprises a locking wheel, a male fixed part and a female fixed part. The male fixed part and the female fixed part of the sternal closure fixator are fixed through meshing of first oblique teeth and second oblique teeth, and when installation is conducted, meshing of the oblique teeth is stable and reliable; when removal is conducted, the distance between the male fixed part and the female fixed part is reduced through the removal tool, at the moment, the first oblique teeth can be extruded by the second oblique teeth, the meshing state between the first oblique teeth and the second oblique teeth is released, therefore, the sternal closure fixator can be effectively removed, and the problem that the sternal closure fixator is difficult to remove due to the fact that the male fixed part is subjected to plastic deformation is avoided.

Description

technical field [0001] The invention relates to a surgical kit for sternal closure and fixation. 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
