A kind of femoral trochanter reduction device

Abstract

The invention discloses a femoral trochanter reduction device, which comprises a first forceps body and a second forceps body, a mounting groove is opened in the first forceps body, and the second forceps body passes through the mounting groove, and is connected to the first forceps body through a rotating shaft. The clamp bodies are connected by rotation, and a clamp body adjustment mechanism for the reduction and adjustment of the femoral trochanter is installed on one side of the first clamp body. The present invention realizes the clamping of the patient's femoral fracture through the mutual cooperation of the first clamp body and the second clamp body. At the same time, use the adjustment rod in the clamp body adjustment mechanism to rotate and fine-tune to adjust the angle of the first clamp body and the second clamp body, so as to reset the femoral fracture, and use the adjustment rod to adjust any angle in the installation port , so as to meet the requirement that the adjustment rod is always selected to the state closest to the perpendicular to the bone contact surface, making the abutment more stable and facilitating the operation.

Description

technical field [0001] The invention relates to the technical field of femoral trochanter reduction, in particular to a femoral trochanter reduction device. Background technique [0002] The femoral trochanter, also known as the trochanter, is a palpable bony protrusion located on the outside of the hip joint. At the root of the femoral neck, there is a rough protrusion protruding outward called the greater trochanter, which is the greater trochanter. The bulge that protrudes backward and inward is called the lesser trochanter, also known as the lesser trochanter. There is an intertrochanteric line in front of the trochanter and an intertrochanteric crest behind it. There are many muscles attached to the trochanter and perform various activities of the hip joint. For example, the muscles that insert on the greater trochanter of the femur include the gluteus medius, gluteus minimus, and piriformis, and the iliopsoas muscles that insert on the lesser trochanter of the femur...

AI Technical Summary

Problems solved by technology

[0003] Existing trochanteric fractures are treated according to the degree of fracture. When the patient is younger and the fracture is more serious, surgical treatment is usually used. There is a device similar to a clip to position and reset the patient's femur. Then adjust the distance between the two jaws to achieve corrective reset. However, since the femur is an irregular plane, it is necessary to find the closest vertical plane for contact when pushing, so as to make the positioning more stable. Existing resting devices cannot effectively adjust the reverse angle, which makes the resting unstable and prone to slipping and other phenomena. Therefore, we propose a femoral trochanter reduction device
