Femoral lesser trochanter fixing device for clinical orthopedic surgery

Abstract

The invention discloses a femoral lesser trochanter fixing device for the clinical orthopedic surgery. The fixing device comprises a lower curved plate, wherein the front end of the upper end surfaceof the lower curved plate is provided with two first elastic bands opposite to each other in the left-right direction, and the rear end of the upper end surface of the lower curved plate is provided with two second elastic bands opposite to each other in the left-right direction, and hooks and loops are arranged on the upper end surfaces of the first elastic bands and the lower sides of the secondelastic bands. The side of the lower curved plate is provided with a ventilation groove, and two fixed rods opposite to each other in the front-back direction are arranged in the middle of the upperend surface of an upper curved plate. The fixing device is simple in structure and convenient to use and capable of avoiding the use of a handle to control the tightness, thereby avoiding adverse effects on drilling caused by the handle and ensuring normal operation of the drilling. A corresponding ventilation device is provided to avoid displacement of the fixing device caused by a large amount of sweat accumulation on the skin surface of a patient and ensure accuracy of the drilling position, so that injury that may be caused to the patient during the lesser trochanter fixing process is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lesser trochanter fixation device for clinical orthopedic surgery. Background technique [0002] Intertrochanteric fractures, also known as intertrochanteric fractures, refer to fractures between the greater and lesser trochanters of the femur, often combined with fractures or extensive fractures of the lesser trochanter. Fractures of the lesser trochanter or extensive fractures cause the femur to resist external loads and torsional forces The mechanical performance of the femoral intertrochanteric fracture decreased significantly, and the proximal part of the fracture was stretched by the iliopsoas, gluteus medius and other external rotator muscles, so that the limbs were flexed, abducted, and externally rotated. Therefore, in the treatment of intertrochanteric fractures, the lesser trochanter Fixation is a factor that cannot be ignored; in the prior art, electric dril...

[0002] Intertrochanteric fractures, also known as intertrochanteric fractures, refer to fractures between the greater and lesser trochanters of the femur, often combined with fractures or extensive fractures of the lesser trochanter. Fractures of the lesser trochanter or extensive fractures cause the femur to resist external loads and torsional forces The mechanical performance of the femoral intertrochanteric fracture decreased significantly, and the proximal part of the fracture was stretched by the iliopsoas, gluteus medius and other external rotator muscles, so that the limbs were flexed, abducted, and externally rotated. Therefore, in the treatment of intertrochanteric fractures, the lesser trochanter Fixation is a factor that cannot be ignored; in the prior art, electric drills are used to drill holes, and steel nails are used to fix the lesser trochanter. However, before using steel nails to fix the lesser trochanter, the position of the lesser trochanter needs to be fixed. Most doctors use their hands to fix the position of the lesser trochanter based on experience. The disadvantages of this method are that the maintenance of the reduction is not firm, the drilling direction is not accurate, and it is easy to hurt the doctor's hand. For example, the patent application publication number 201320041408.4 A femoral lesser trochanter fixation device for clinical orthopedic surgery is disclosed, but the above patents have certain defects in the use process. In this patent, the distance between the arc covers is adjusted by the handle on the handle to fix the lesser trochanter On the one hand, although the angle of the handle can be adjusted during the operation, if the angle of the handle is adjusted, the distance between the arc covers cannot be adjusted. The process is hindered and the structural design is unreasonable. On the other hand, the fixation device lacks a corresponding ventilating structure. During the fixation of the patient's lesser trochanter, the fixation device may be displaced due to sweat accumulation at the fixation part of the patient, affecting the accuracy of the drilling position. precision
