Problems solved by technology

[0002] At present, patients with femoral neck fractures are subjected to the method of subjectively driving screws on the eye side under fluoroscopy. The needle distance is often variable and easy to repeat, which may cause potential damage to the sciatic nerve. The artificial leg alignment requires two assistants to maintain the operation. There are technical deficiencies, the drilling tool should be improved, and the surgical position fixation jig and internal fixation device should be installed. It is urgent to develop a disposable surgical reduction device for femoral neck fractures for clinical application.

Abstract

The invention discloses a disposable femoral neck fracture operation repositor which comprises a lower limb frame, a drill jig, a transverse position adjusting clamp, a lower thigh fixing clamp and an inner fixing device. At present, patients with femoral neck fractures are treated by objectively and visually inserting screws under fluoroscopic control, the problems of inaccurate positioning, unequal needle pitch and not straight screw holes frequently occur, the potential harm of causing sciatic nerve lesions is possible to occur repeatedly, and the effect of operation is affected. Aiming at the defects of the prior art, the transverse position adjusting clamp and the lower thigh fixing clamp are used for fixing operation positions of patients and improving the drill jig. By adopting the drill jig method, arranging a special gang drill to insert screw and arranging the inner fixing device, the operating angle and accurate positioning required in clinic are satisfied, inner fixing is implemented, and the defects of the traditional uncontrolled operating method for holding the thigh to position by hand and inserting screws in single drill holes are overcome. The disposable femoral neck fracture operation repositor has the characteristics of operation convenience and safety and accurate repositioning, and the strength quality of inner fixing and the operation effect are improved. The disposable femoral neck fracture operation repositor is applicable to the clinic application to disposable repositioning of patients with femoral neck fractures.

Description

technical field [0001] The invention relates to a disposable surgical reduction device for femoral neck fracture. Background technique [0002] At present, patients with femoral neck fractures are subjected to the method of subjectively driving screws on the eye side under fluoroscopy. There are often potential hazards that may cause sciatic nerve damage due to different needle distances, and artificial leg alignment requires two assistants to maintain the operation. There are technical deficiencies, the drilling tool should be improved, and the surgical position fixation jig and internal fixation device should be installed. It is urgent to develop a disposable surgical reduction device for femoral neck fractures for clinical application. Contents of the invention [0003] Disposable surgical reduction device for femoral neck fracture, comprising a lower limb body frame 1, a drilling template 2, a lateral position adjustment jig 3, a lower femur fixation jig 4, and an inte...
