Abstract

The invention relates to the technical field of medical instruments, and especially relates to a patellar prosthesis and a total knee prosthesis. The patellar prosthesis comprises a prosthesis main body, a rotator and patella fixing parts; the prosthesis main body has a first surface and a second surface which are opposite to each other; the first surface is provided with a main body groove cooperated and connected with the rotator, and the second surface is connected with the patella fixing parts; the main body groove can prevent the rotator from being separated from the prosthesis main body; and the rotator is protruded from the first surface and can rotate around an axis thereof; The total knee prosthesis comprises the patellar prosthesis. The purpose of the present invention is to provide the patellar prosthesis and the total knee prosthesis so as to solve the technical problem of serious abrasion of a patellar prosthesis in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a patella prosthesis and an artificial knee joint. Background technique [0002] The artificial knee prosthesis is implanted into the human body after knee replacement, and its function is to restore the normal physiological functions of the human body. The replacement of the patella with severe degeneration and wear has been accepted by everyone. The design of the mainstream knee prosthesis in the market has fully considered the matching of the patellofemoral prosthesis, and a long and wide trochlear groove is set in front of the femoral prosthesis. With the extensive application of patella replacement, the design of patella prosthesis has become an important factor affecting the effect of artificial knee replacement. [0003] At present, the design of patella prosthesis is generally in the form of integral fixation or assembly fixation. This type of patella prosthesis ...
