Embodiment 1
[0047] refer to Figure 1 to Figure 5 , the present embodiment provides a curved bone knife, including a handle 101 and a blade body 103, the blade body 103 includes a connecting portion 104, a bending portion 105 and a knife edge 106, the connecting portion 104 is installed on the handle 101, and one end of the bending portion 105 is connected to the The knife edge 106 is connected to the end of the bent portion 105 away from the connecting portion 104 .
[0048] Due to the special material of the knee joint prosthesis, the price is also expensive, but when the knee joint is revised, it is necessary to separate the lateral part of the tibial prosthesis from the lateral tibial plateau, and the lateral part is blocked by the patella and quadriceps femoris. Stable tibial prostheses are difficult to remove.
[0049] This embodiment provides a curved bone knife that can be used for revision of the knee joint prosthesis. The blade 103 is provided with a bending part 105, which can...
Embodiment 2
[0060] This embodiment provides a bone knife for a prosthesis, including the above curved bone knife.
[0061] The bone knife for the prosthesis provided in this embodiment includes the above-mentioned curved bone knife, which can well bypass the patella and quadriceps, thereby separating the lateral part of the tibial prosthesis from the lateral tibial plateau, and then can complete the adjustment of the knee joint. Removal of a stable tibial prosthesis during prosthetic revision.
