[Abstract] the utility model discloses a acetabulum file, which comprises a skeleton made of medical stainless steel material and a blade made of medical stainless steel material arranged on the skeleton. The skeleton comprises at least two supporting rods distributed on the same cone surface, each supporting rod is respectively provided with a blade, the blade is arc-shaped, and the blades of each blade are arranged on the same On the spherical surface, the blade is fixedly connected with the support rod. The acetabulum file has simple structure, large Kwai master cost, convenient operation, high cutting surface smoothness, and can accelerate the operation process, improve the operation efficiency and the accuracy of the operation.

[Patent Description] acetabulum file

[technical field]

[0001] the utility model relates to the field of medical devices, in particular to a acetabulum setback used in hip joint surgery.

[background technology]

[0002] acetabulum file is a necessary medical device for hip surgery. The existing acetabulum file is usually spherical in structure. There are many round holes on the spherical surface, and cutting teeth are set at the round holes. During the operation, the necrotic tissue is cut off at the hip joint of the patient through the cutting teeth. Because the cutting teeth are distributed discretely, the cutting surface is not continuous and the flatness is poor. Another kind of acetabulum file is in the shape of A S-shaped or cross shaped blade is arranged on the spherical support body. The blade of this hip white file is connected with the support body through a connection ring at the end of the blade. This connection mode leads to unstable connection between the middle part of the blade and the support body. When the acetabulum file is used, the blade is easy to shift, resulting in deformation of the cutting surface and affecting the accuracy of the operation. Therefore, the existing acetabulum file needs to be improved.
