Fixing device for femoral greater trochanter fracture

Abstract

The invention relates to the technical field of medical auxiliary equipment, and discloses a fixing device for greater trochanter fracture of femur, the fixing device comprises a longitudinal rod I and a longitudinal rod II, the longitudinal rod I is located in front of the longitudinal rod II, the longitudinal rod I and the longitudinal rod II are both internally provided with a plurality of through holes I, binding wires penetrate through the through holes I, and the binding wires penetrate through the longitudinal rod II. First inner grooves are formed in the upper portions of the interiors of the first longitudinal rod and the second longitudinal rod correspondingly, the upper surfaces of the interiors of the first inner grooves communicate with the exterior, and first springs are fixedly connected to the lower surfaces of the interiors of the first inner grooves. The lower end of the first longitudinal rod and the lower end of the second longitudinal rod both straddle the front edge and the rear edge of the lateral femoris muscle so that the device can be pre-fixed and then fixed through the binding wire, and therefore the device is simple in overall operation, meanwhile, the distance between the first longitudinal rod and the second longitudinal rod can be adjusted according to different people when the device is used, and the device is convenient to use. And therefore, the overall practicability of the device is relatively high.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a fixation device for fractures of the greater trochanter of the femur. Background technique [0002] Intertrochanteric fracture of the femur is a common clinical fracture, accounting for about 3.9% of the whole body fractures, especially most patients with intertrochanteric fractures are elderly patients with osteoporosis, often accompanied by serious complications of the cardio-cerebral system, and if Fractures cannot be treated in time, and the patient's systemic condition often deteriorates rapidly, followed by fatal complications such as hypostatic pneumonia and deep vein thrombosis. Therefore, it is one of the most difficult types of fractures in clinical practice. In some patients with intertrochanteric fractures combined with displacement of large and small trochanteric fractures, in order to obtain early functional exercise, the fractures of the great...

Problems solved by technology

At present, the commonly used fixation methods in clinical practice are: 1. Simple cerclage: steel wire or titanium cable is used to bind the intertrochanteric space in a circular manner, which can provide good lateral fixation for large bone blocks with good bone quality, but the intertrochanteric space of the elderly Fractures are often accompanied by varying degrees of osteoporosis, and the greater trochanter is mostly a comminuted fracture. Simple cerclage is easy to slide, and small bone fragments cannot be fixed, and cut the loose bone, res
