Description
Technical Field
The utility model relates to the field of medical instruments, in particular to a fixing plate for reconstruction after thoracotomy.
Background
The conventional method for closing the sternum is to use the steel wire to tie and fix the whole sternum up and down, and the steel wire is used by the surgeon to tighten the sternum cut left and right with a suture needle connected with the steel wire, so that the cut sternum is closed and fixed. The traditional steel wire sternum fixation method has the following defects: 1. the fixing tightness is difficult to grasp and unify. 2. The steel wire is easy to cut the sternum, so that the sternum is cracked, and adverse effects are brought. 3. The steel wire threading has certain difficulty.
However, with the continuous improvement of the sternum internal fixation system, the conventional stainless steel wire binding and kirschner wire internal fixation not only takes a long time for the operation, but also has relatively complicated operation, much bleeding during the operation, poor tissue compatibility, unstable fixation, and easy defects of loosening, shifting, breaking and the like at the fracture end, and is gradually replaced by the sternum fixator.
The common sternum fixator is locked by expanding the sternum fixator through a long shaft of the cam, and the position of the sternum can be fixed only after the cam is rotated, but under the action of external disturbance, the cam can directly cause the sternum fixator to be loosened in case of loosening or locking.
The utility model is provided for overcoming the defects of the prior art.
