Femoral trochanter reduction device

Abstract

The invention discloses a femoral trochanter reduction device, which comprises a first pincer body and a second pincer body, a mounting groove is formed in the first pincer body, the second pincer body penetrates through the mounting groove and is rotationally connected with the first pincer body through a rotating shaft, and a pincer body adjusting mechanism for femoral trochanter reduction adjustment is mounted on one side of the first pincer body. According to the invention, the femoral fracture of a patient can be clamped through the cooperation of the first pincer body and the second pincer body, and meanwhile, an adjusting rod in the pincer body adjusting mechanism is finely adjusted to adjust the angle of the first pincer body and the angle of the second pincer body, so that the femoral fracture is reduced; the adjusting rod can be adjusted at any angle in the mounting port, so that the adjusting rod is always in a state closest to and perpendicular to the bone contact surface,jacking is more stable, and is convenient for operation.

Description

technical field [0001] The invention relates to the technical field of femoral trochanter reset, in particular to a femoral trochanter reset device. Background technique [0002] The femoral trochanter, also known as the trochanter, is a palpable bony bulge located on the outer surface of the hip joint. At the root of the femoral neck, there is a rough bulge that protrudes outward and is called the greater trochanter, which is the greater trochanter. The bulge that protrudes posteriorly and inwardly is called the lesser trochanter, also known as the lesser trochanter. There is an intertrochanteric line in front of the large and small intertrochanters, and an intertrochanteric crest in the back. There are many muscles attached to the large and small tuberosities to complete various activities of the hip joint. For example, the muscles that attach to the greater trochanter of the femur include the gluteus medius, gluteus minimus, piriformis, etc., and the iliopsoas muscle o...

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
