Description

Tibiofibular syndesmosis fixing device that resets down

Technical Field

The utility model relates to a clinical treatment auxiliary assembly technical field especially relates to a tibiofibula combined reduction fixing device down.

Background

Currently, clinical reduction means aiming at the combined separation of the lower tibiofibula include the combined incision of the lower tibiofibula for direct vision reduction and the reduction of the forceps jaws of reduction forceps. The fixing means comprises a loop steel plate fixing method, a lag screw fixing method, an anchor fixing method, a tibiofibular anterior ligament repairing or reconstructing method and the like. Reduction under direct incision is rarely used by clinicians due to the existence of larger trauma, the reduction forceps jaw reduction technology is difficult to achieve ideal anatomical reduction due to the characteristic of point-to-point reduction, once fixation is carried out on the premise of poor reduction, complications such as internal fixture fracture, unstable ankle joint and the like occur, so that satisfactory treatment effect cannot be achieved no matter what fixing mode is selected in the case of poor reduction, and finally immeasurable economic loss and dysfunction are brought to patients. In the prior art, a pulling force technology is also adopted for reduction, and the method is that holes are directly drilled in the lateral cortex of a fibula, penetrate through the medial cortex of the fibula, penetrate through the lateral cortex of a tibia, the hole channels are positioned on a straight line, a pulling screw is screwed in or a loop steel plate is led in, and the fibula is extruded to the tibia by the pressing of the screwed screw or the knot of the loop steel plate. There is a serious problem in this procedure, that is, whether the lag screw or the steel plate is pressed, the fibula moves along a straight line, that is, the final position of the fibula is the position of the tibial lateral cortical opening, and the fibula cannot be anatomically reset unless this point is just hit at the innermost point of the tibial lateral groove. Simultaneously the fibula can appear outward turning when shin fibula is united to separate down, and current point-to-point reset technique can only crowd the fibula to the shin bone, and can't correct the problem that the fibula is outward turned, simultaneously, because lag screw is harder and the fixed strength of tong "pan" steel sheet is relatively weak, so can't resume bearing a burden in early stage at postoperative patient, this again serious reduction patient's quality of life.
