Problems solved by technology

[0002] At present, most of the ankle tibial trays are revision tibial trays. The amount of osteotomy in the revised tibial tray is large, and the operation is more complicated. At the same time, the fixation method of the tibial end of the revised tibial tray is easy to fall off and cannot integrates well with the tibia
The above shortcomings directly affect the effect of ankle joint replacement surgery in ankle joint replacement surgery. At the same time, the implantation on the tibial side cannot be performed stably, which greatly affects the stability of ankle joint replacement surgery.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] In order to shorten the operation time, improve the intraoperative experience of the operator and the effect of bare joint replacement, the present invention provides an integrated primary ankle tibial plateau prosthesis, according to Figure 1-Figure 4 shown, including:

[0027] The tibial tray body 1 is provided with a snap-in groove 11 for fitting with the tibial pad;

[0028] The hollow cylinder 2 is used to implant and fix the tibial osteotomy, so that the hollow design effectively reduces the amount of osteotomy and preserves the tibia to the greatest extent;

[0029] Connector 3, the two ends of which are respectively connected to the tibial tray body ...

Abstract

The invention provides an integrated primary ankle joint tibial plateau prosthesis, which comprises a tibia support body, wherein a clamping groove matched with a tibia liner is formed in the tibia support body; a hollow cylinder used for being implanted into a tibia osteotomy position and fixing the tibia osteotomy position; a connecting piece the two ends of which are connected with the tibia support body and the hollow cylinder respectively, so that the connecting piece and the hollow cylinder are implanted into the tibia osteotomy; wherein the hollow cylinder is arranged along the length direction of the tibia support body; the tibia support body, the connecting piece and the hollow cylinder are integrally formed. The prosthesis has the advantages that the operation of mounting the tibia handle in an operation is reduced, the operation steps are simplified, the operation time is shortened, and the operation experience is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an integrated primary ankle tibial plateau prosthesis. Background technique [0002] At present, most of the ankle tibial trays are revision tibial trays. The amount of osteotomy in the revised tibial tray is large, and the operation is more complicated. At the same time, the fixation method of the tibial end of the revised tibial tray is easy to fall off and cannot be used. Combines well with the shin. The above-mentioned shortcomings directly affect the effect of ankle joint replacement surgery in ankle joint replacement surgery. At the same time, the implantation on the tibial side cannot be performed stably, which greatly affects the stability of ankle joint replacement surgery. Contents of the invention [0003] The present invention provides a one-piece primary ankle tibial plateau prosthesis, with the purpose of overcoming at least one of the above-mentioned technical ...
