Problems solved by technology

[0003] When installing the external fixator for Ilizarov hip reconstruction, at least 4 steel needles need to be pierced through the two ends of the proximal osteotomy, and then the 4 steel needles are connected with an arc-shaped connecting rod and a steel needle fixing rod. Completed the installation of Ilizarov's proximal femoral osteotomy external fixator, but the connection method of the arc-shaped connecting rod, steel pin clamp and steel pin fixation rod is very rigid, and the required angle is difficult to adjust in place, so it makes the pro...

Abstract

The invention discloses a universal joint device for an Ilizarov hip proximal femur osteotomy external fixing frame, which belongs to the technical field of medical equipment and comprises a rotating shaft, a connecting rod connected with a steel needle fixing rod, a plurality of adjusting bases arranged on the rotating shaft in a sleeving manner and a locking mechanism capable of locking the adjusting bases on the rotating shaft, the connecting rods are hinged to the two ends of the adjusting base through spherical hinge assemblies, and each spherical hinge assembly comprises a universal ball fixedly connected with the corresponding connecting rod and a spherical hinge locking mechanism capable of locking the universal ball to the adjusting base. The universal joint device can serve as a connecting pivot of a steel needle fixing rod in the Ilizarov hip femoral proximal osteotomy external fixing frame, the angle and the deflection direction of the steel needle fixing rod can be flexibly changed, and therefore the universal joint device can actively adapt to the position of a steel needle, the arrangement requirement for the steel needle is lowered, unstressed installation can be achieved, and the safety of the steel needle is improved. The arrangement difficulty of the Ilizarov hip femoral proximal osteotomy external fixing frame is greatly reduced, and the development of related medical operations is promoted.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a universal joint device for an Ilizarov hip femoral proximal osteotomy external fixator. Background technique [0002] In the Ilizarov hip reconstruction surgery, the amputated part needs to be fixed with the Ilizarov hip reconstruction external fixator to assist subsequent recovery. The Ilizarov hip reconstruction external fixator usually consists of the Ilizarov proximal hip femoral osteotomy external fixator for fixing the Ilizarov hip proximal femoral osteotomy and the distal femoral external fixation for fixing the distal femur, the Ilizarov hip femoral The proximal osteotomy external fixator usually includes several steel needles, steel needle clips, steel needle fixing rods and arc-shaped connecting rods. For example, the invention patent with the patent number "201710295139.7" and the patent title "A Combined Hip Joint External Fixator" discloses a hip joint e...
