骨填充假体Bone filling prosthesis

技术领域technical field

本发明涉及医疗领域，具体而言，涉及一种骨填充假体。The present invention relates to the medical field, in particular, to a bone filling prosthesis.

背景技术Background technique

骨缺损是骨科医师经常遇见的问题，目前，关于骨缺损使用的填充假体分为一体式和组配式。一体式填充假体只是对缺损位置进行物理填充，并不存在调节功能；而组配式假体是两个或多个组件配合使用，目的是获得良好的初始稳定性。Bone defect is a common problem encountered by orthopedic surgeons. At present, the filling prostheses used for bone defects are divided into one-piece and modular. The one-piece filling prosthesis only physically fills the defect position and has no adjustment function; while the modular prosthesis is the use of two or more components in order to obtain good initial stability.

但是，在临床使用时，骨缺损的腔隙的长度不一，填充假体的长度需要与骨缺损的腔隙的长度相匹配，即需要调节填充假体的长度，以使其长度与骨缺损的腔隙的长度相匹配。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 to make its length match the length of the bone defect. match the length of the cavity.

可见，现有的组配式填充假体并不能根据骨缺损的腔隙的长度来调节自身长度，这对组配式填充假体在临床应用中造成了极大的不便。It can be seen that the existing modular filling prosthesis cannot adjust its length according to the length of the cavity of the bone defect, which causes great inconvenience to the clinical application of the modular filling prosthesis.
