Embodiment Construction

[0032] 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.

[0033] The present invention provides a tibial prosthesis, including a tibial platform 10 and an extension stem 20, please refer to Figure 1 to Figure 6 , the tibial prosthesis also includes: a transition part 30, the transition part 30 is arranged between the tibial platform 10 and the extension handle 20; wherein, the position of the transition part 30 is adjustable on the tibial platform 10, so that the extension handle 20 passes through the transition part 30 is adjustably mounted on the tibial plateau 10 along the position of the end face of the tibial plateau 10 .

[0034] The tibial prosthesis of the present invention is provided with a position-adjustable transition part 30 between th...

Abstract

The invention provides a tibial prosthesis. The tibial prosthesis comprises a tibial platform, an extension shank and a transition part. The transition part is arranged between the tibial platform and the extension shank and arranged on the tibial platform in a positional adjustable manner to enable position-adjustable mounting of the extension shank on the tibial platform along the end face of the tibial platform through the transition part. The tibial prosthesis has the advantage that the problem of eccentricity non-adjustability of a tibial prosthesis in the prior art is solved.

Description

technical field [0001] The invention relates to the field of artificial prosthesis, in particular to a tibial prosthesis. Background technique [0002] Today, total knee replacement surgery has become an important means of relieving patients' pain and correcting deformity and other diseases. Total knee joint revision surgery has also become the most fulfilling operation for joint surgeons. In revision surgery, the revision prosthesis generally uses a modular prosthesis to achieve good fixation. [0003] At present, the design of the revision tibial prosthesis is that the tibial plateau is connected with an extended stem, and a filler block can be used when the bone defect is serious. In common tibial prosthesis assembly, there are two types of extension stems: straight stem and eccentric stem, which can solve the partial eccentricity needs, but the eccentricity cannot be adjusted. [0004] For patients with severe bone defects and severe anatomical deformities, modular rev...
