Abstract

The invention discloses a bone lengthening scaffold. The bone lengthening scaffold comprises a first connecting rod assembly, a front end transfer sliding block assembly, a tail end rotating sliding block assembly and sliding rails, wherein the guide rails serve as a main scaffold; the front end transfer sliding block assembly and the tail end rotating sliding block assembly are connected onto the guide rails in a sliding fit manner; the first connecting rod assembly is connected with the front end transfer sliding block assembly and the tail end rotating sliding block assembly. The positions of the front end transfer sliding block assembly and the tail end rotating sliding block assembly on the sliding rails can be adjusted by adjusting the first connecting rod assembly.

Description

technical field [0001] The invention relates to a medical bone extension bracket. Background technique [0002] With the development of society and the advancement of science and technology, people's living standards have been continuously improved. With the improvement of people's living standards, people's attention to health is also gradually increasing, which also leads to the continuous improvement of medical conditions and promotes the development of medical devices. [0003] For example, taking bone lengthening surgery as an example, a bone lengthening bracket is usually used to fix the broken bone. [0004] However, the existing medical bone extension brackets have a fixed length and size, and cannot be reasonably adjusted according to different situations. The adjustment is inconvenient, the distance is short, the amount of joint movement or the rotation angle is small, the adjustment is imprecise, the overall weight is large, and the use is difficult. [0005] Th...
