Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] The invention provides an osteotomy plate, such as figure 1 and 2 As shown, the osteotomy plate includes: a fixed plate 1; a guide plate 3, which is connected to the fixed plate 1 and protrudes from the fixed plate 1 in a direction perpendicular to the plate surface of the fixed plate 1, and the guide plate 3 is along the plate of the fixed plate 1. An osteotomy groove 2 is opened in the face direction.

[0022] During use of the osteotomy plate of the present invention, the fixation plate 1 is inserted into the gap between the tibia and the femur to position the osteotomy plate, and then the osteotomy groove 2 on the guide plate 3 is used to guide the osteotomy saw blade, Perform ost...

Abstract

The invention provides an osteotomy plate and a tibial osteotomy method. The osteotomy plate comprises a fixing plate and a guide plate. The guide plate is connected with the fixing plate and is protruded out of the fixing plate along the direction which is perpendicular to plate surfaces of the fixing plate, and an osteotomy groove is formed in the guide plate along the directions of the plate surfaces of the fixing plate. According to the technical scheme, the osteotomy plate and the tibial osteotomy method have the advantages that the osteotomy plate is simple in structure and is light, the single tool can have functions of four or five tools in the prior art, and accordingly osteotomy operation can be simplified; the osteotomy plate is in an integral design, accordingly, cracking risks in osteotomy procedures due to diversified welding tools can be prevented, and the problem of osteotomy termination due to breakage of osteotomy tools can be solved; knee joints required to be subjected to osteotomy are subjected to osteotomy at 90-degree flexed positions in osteotomy procedures by the aid of the traditional osteotomy tools, but can be subjected to osteotomy at the 90-degree flexed positions by the osteotomy plate and also can be subjected to osteotomy at extension positions by the osteotomy plate, accordingly, lower extremity force lines can be measured while the knee joints are subjected to osteotomy, and the osteotomy accuracy can be improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an osteotomy plate and a tibial osteotomy method. Background technique [0002] Total knee replacement has been around for a long time. It mainly uses surgical tools to remove the position of the joint and then implants an artificial knee prosthesis to improve the quality of life of the user and eliminate pain. Among them, the elimination of tibial side lesions is mainly achieved through tibial osteotomy during the operation. During the tibial osteotomy process, some auxiliary tools are needed for positioning and determining the osteotomy position. After the saw blade is connected to the power, the desired effect can be achieved through the osteotomy groove on the auxiliary tool. [0003] Common tibial osteotomy tools are usually composed of a tibial extramedullary positioning system and a tibial osteotomy module. The tibial osteotomy module is installed after the positioning ...
