Embodiment Construction

[0018] like figure 1 As shown, the reduction retractor for femoral neck fractures according to the present invention comprises a bracket 1, a longitudinal support rod 2 arranged on the bracket 1 and two transverse support rods arranged on the bracket 1 and located on both sides of the longitudinal support rod 2 3. The upper end of the longitudinal support rod 2 is provided with a bracket 4 for abutting on the perineum, and the two lateral support rods 3 are respectively provided with foot rests 5, which are connected by a universal adjustment mechanism 6. on the lateral support rod 3. The universal adjustment mechanism 6 includes a connecting seat 61 installed on the lateral support rod 3, a universal joint 62 and a locking knob 63 installed on the connecting seat 61. After the universal joint 62 is adjusted to the use position It is fixed on the connection seat 61 by the locking knob 63, and the universal joint 62 is fixedly connected with a hard support plate 65, and the fo...

Abstract

A reduction tractor for a surgery of fracture of the neck of a femur comprises a support, a longitudinal supporting rod and two transverse supporting rods, wherein the longitudinal supporting rod is arranged on the support; the two transverse supporting rods are arranged on the support and are positioned on two sides of the longitudinal supporting rod; a bracket which is abutted to a perineum portion is arranged at the upper end of the longitudinal supporting rod; and foot supports are separately arranged on the two transverse supporting rods, and are connected to the transverse supporting rods through universal adjusting mechanisms. By the universal adjusting mechanism, internal retracting and external stretching of traction of the shaft of the femur of an affected side before the surgeryare implemented, the shaft of the femur of the affected side is adjusted to a shenton's line continuously according to an alignment condition, reduction adjustment is quite convenient, and the usingeffect is good.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a reduction and distractor for femoral neck fracture surgery. Background technique [0002] Femoral fractures, especially femoral neck fractures, are common clinical injuries, which are common in the elderly. Based on physiological and anatomical factors and the contractile force of muscle groups, it is difficult to restore after fracture. In addition, the poor blood supply of the femoral head in the elderly is easy to cause defects. Blood necrosis requires dynamic hip screw fixation (DHS) with tension and static compression. However, the existing reduction and distractor used for femoral neck fracture surgery usually has a fixed foot support, which cannot realize the adjustment of adduction and abduction in space, so the use effect is not ideal. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a reduction and distractor for femoral neck fract...
