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
Therefore, a sternal closure fixer has been designed, which has a male fixer and a female fixer. Both the male fixer and the female fixer have a set of positioning holes and screw holes. The operation of the fixator will inevitably cause errors and uneven force, which will affect the success rate of the operation

The invention discloses an installation tool for a sternum closing fixator. The installation tool comprises a rack and two retractor arms. The retractor arms are sleeved on the rack, each retractor arm is provided with a non-return mechanism capable of limiting the retractor arm to move correspondingly to the rack, one of the retractor arms is provided with a driving mechanism capable of driving the same to move correspondingly to the rack, and the bottom of each retractor arm is provided with a positioning boss and a fixing screw which are capable of mutually matching with the sternum closing fixator. The installation tool can be used for positioning and fixing the sternum closing fixator so as to have sternum evenly fixed, degree of tightness is controllable, operation is facilitated and fixation is stable.
Description
technical field [0001] The invention relates to a sternal closure fixer installation tool, which belongs to the field of medical instruments. Background technique [0002] At present, in the treatment requiring thoracotomy, the entire sternum is cut open. At the end of the treatment, the entire sternum is bound up and down with steel wires, and the left and right sides are cut by the surgeon with a needle connected to the steel wire. The opened sternum was tightened with a steel wire, so that the incised sternum was closed and then 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. Therefore, a sternal closure fixer has been designed, which has a male fixer and a female fixer. Both the male fixer a...
