Abstract

The invention provides a bone filling prosthesis. The bone filling prosthesis comprises a first prosthetic block, a second prosthetic block, length adjusting components and a first elastic member. Thefirst elastic member is arranged between the first prosthetic block and the second prosthetic blocks, so as to connect the first prosthetic block with the second prosthetic block through the first elastic member. At least part of each length adjusting component is retractably arranged between the first prosthetic block and the second prosthetic block, the length of the bone filling prosthesis isregulated through adjustment of the distance between the first prosthetic block and the second prosthetic block, and accordingly, the bone filling prosthesis can be matched with bone defects with different cavity gap lengths. By the bone filling prosthesis, the problem of incapability of adjusting the length of bone filling prostheses in the prior art is solved.

Description

technical field [0001] The invention relates to the medical field, in particular to a bone filling prosthesis. Background technique [0002] Bone defect is a problem often encountered by orthopedic surgeons. At present, the filling prosthesis used for bone defect is divided into one-piece type and modular type. The one-piece filling prosthesis only physically fills the defect without any adjustment function; while the modular prosthesis uses two or more components together to obtain good initial stability. [0003] However, in clinical use, the length of the cavity of the bone defect is different, and the length of the filling prosthesis needs to match the length of the cavity of the bone defect, that is, the length of the filling prosthesis needs to be adjusted so that its length matches the length of the bone defect. match the length of the cavity. [0004] It can be seen that the existing modular filling prosthesis cannot adjust its length according to the length of the...
