Hip joint dislocation reset traction device

Abstract

The invention relates to a hip joint dislocation reset traction device, which consists of an ilium bone needle, an ilium bone needle clamp, a connecting plate, a triangular force application frame, regulating and fixing screw nuts, an auxiliary guide rail, a near end thigh bone needle clamp, a main guide rail, a thigh bone needle, a far end thigh bone needle clamp and a guide sleeve, wherein the ilium bone needle clamp is a plate element with the curvature similar to the curvature of the human body ilium bone and is combined with the ilium bone needle, the lower part of the ilium bone needle clamp is connected with the connecting plate, the connecting plate is screwed with the main guide rail, the triangular force application frame is fixedly clamped on the main guide rail, the auxiliary guide rail is arranged on the triangular force application frame in a penetrating way, and the regulating and fixing screw nuts and screws are respectively used for combination. The far end thigh bone needle clamp and the near end thigh bone needle clamp are respectively arranged at the far end of the main guide rail in a penetrating way, the regulating and fixing screw nuts are respectively screwed on the main guide rail arranged at the two sides, and the thigh bone needle is penetrated and clamped on the near end thigh bone needle clamp and the far end thigh bone needle clamp. The hip joint dislocation reset traction device is applicable to hip joint dislocation reset, is also applicable to hip joint dislocation reset and patients with short sick legs requiring the thigh bone lengthening, is also applicable to hip joint dislocation reset and patients with sick legs requiring thigh bone shortening, and can also be used for femoral head slipped epiphysis correction on juveniles.

Description

technical field [0001] The invention relates to the field of orthopedics. In particular, the invention relates to a hip joint dislocation reset traction device which needs to be reset due to hip joint dislocation and femoral epiphyseal slippage. Background technique [0002] The hip joint is a movable joint composed of the femoral head and the acetabulum on the ilium. When the femoral head is separated from the socket, it will cause hip dislocation. It often becomes old hip dislocation due to untimely reset. The dislocation distance Sometimes it reaches a few centimeters, and often a new socket is formed at the dislocated position for several years, which affects people's movement. Because the new acetabulum is too small, not only the support is unstable, but at a certain age, it will cause pain and difficulty in moving, and it is easy to cause Deformation or necrosis of the femoral head. To fix this problem it should be reset. For mild dislocations or fresh hip dislocati...

AI Technical Summary

Problems solved by technology

However, for old hip dislocations, especially those with large dislocation distances, it is very difficult or even impossible to complete the reduction task with the above-mentioned methods.

The side effects of surgery are too large, and the effect is not ideal. If it is a child, it will affect its development and future life. For adults, it will affect its work and sports, and seriously affect his quality of life.

In some juvenile patients, the epiphysis of the femoral head is also prone to slippage due to external force or other reasons, and it cannot be reset by skin traction or ordinary force.
