Abstract

The invention discloses an auxiliary positioning and screw placement device for a proximal femur intramedullary nail, which comprises an arc-shaped positioning through cylinder, a femur trochanter positioning needle, a first screw, a second screw and a working channel assembly, wherein the arc-shaped positioning through cylinder is of a quarter arc structure; a positioning needle channel is transversely formed in one end of the arc-shaped positioning through cylinder, the femoral trochanter positioning needle is movably inserted into the positioning needle channel through a first screw, and the needle point of the femoral trochanter positioning needle faces the circle center of the arc-shaped positioning through cylinder; the other end of the arc-shaped positioning through cylinder is provided with a threaded hole, the second screw is movably inserted into the threaded hole in the other end of the arc-shaped positioning through cylinder, and the working channel assembly is movably arranged at the other end of the arc-shaped positioning through cylinder through the second screw. The auxiliary positioning and nail placing device for the proximal femoral nail is simple in structure, accurate positioning can be achieved, and the perspective frequency is reduced.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to an auxiliary positioning and nailing device for intramedullary nails at the proximal end of the femur. Background technique

[0002] Hip fracture is a common low-energy injury in the elderly, 90% of which occur in people over 65 years old, and the incidence rate increases sharply in people over 70 years old. Within 1 year after the fracture, 20% of patients will die from various complications, about 50% of patients will be disabled, and the quality of life will be significantly reduced. The intertrochanteric fracture is the most common clinical one, accounting for about 50% of hip fractures.

[0003] At present, most scholars believe that early surgical treatment is the first choice for intertrochanteric fractures. The principle of surgical treatment is to accurately reduce the fracture, firmly fix it, and get off the ground as soon as possible, so as to ultimately improve the ...
