Embodiment Construction

[0009] In the drawings, the holder (1) is made of memory alloy sheet material. During the operation, the affected bone (2) is exposed according to the conventional method, and after reduction treatment, a fixator that is about 10% smaller than the affected bone (2) is selected, and after disinfection, it is soaked in cold saline at 0-5°C for 3- After 5 minutes, take it out, quickly clamp it on the affected bone that has been reset, and then apply the fixator (1) with sterile saline gauze at 45°C to take advantage of the characteristics of the memory alloy material to quickly restore it to its original state and hold the affected bone tightly ( 2).

Abstract

An intertrochanteric fracture fixing apparatus, belongs to the medical appliance field. At present the sheet type external fixator of the intertrochanteric fracture is difficult to enclasp the bones of the patients because of the self elasticity, which is a puzzle in the surgery and made of the innocuous memory alloy sheet material. The bone of the patients is exposed according to the general method in the surgery, after the reset process, the fixing apparatus is selected having the outline size smaller than the bone of the patients about 10%, then dips in the cool brine of 0-5 DEG for 3-5 minutes after antisepsis and is extracted, which is fast blocked on the diaplastic bone of the patients, then foments the fixing apparatus using the disinfectant brine gauze of 45 DEG, and makes a quick recovery to enclasp the bone of the patient. The operation is convenient, and the fixing apparatus is used to enclasp the bone of the patient, which is beneficial to the healing.

Description

Technical field [0001] The invention belongs to the field of medical devices. Background technique [0002] At present, the thin-plate external fixator for intertrochanteric fractures is difficult to hold the affected bone because of its own elasticity, which is a difficult problem for surgery. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problem of treating the intertrochanteric fracture of the femur, so that the thin-plate external fixator can be operated conveniently and embrace the affected bone. [0004] The technical scheme of the present invention is: an intertrochanteric fracture fixator, which is characterized in that it is made of memory alloy thin plate material. [0005] During the operation, the affected bone is exposed according to the conventional method, and after reduction treatment, choose a fixator that is about 10% smaller than the external size of the affected bone. It is stuck on the affected bone that has b...
