The utility model relates to the technical field of medical devices, in particular to an acetabulum file

Background technology

Acetabulum file is a kind of medical instrument used to remove the cartilage and part of bone tissue of the acetabulum. The existing acetabulum file has been used in the operation for several years. Due to the imperfect design, there will be some unearthing during the grinding process

Wei's bone, the acetabular fossa that can not be created, is not conducive to the implantation of products. The grinding efficiency of acetabulum file is low, the heating speed is too fast, and the effect of cutting is not good. The supporting structure of acetabulum file is welding

As a result, the risk of corrosion is increased at the welding position, the torque strength of the support frame is low, and the concentricity of the file body and the support frame is not high after welding. When the acetabulum file is used in combination with the connector, it will cause the acetabulum file to be operated on

Because of the large midrun, the size of the filed acetabular fossa is not accurate. The doctor can not select the implant model accurately, which delays the operation time.

Content of utility model

In the embodiment of Bian utility model, a acetabulum file is provided, which can effectively avoid the phenomenon that the bone is not ground flat in rabbits, and ensure the cutting effect of acetabulum socket body
