Embodiment Construction

[0042] The following is a further non-limiting detailed description of the technical solution of a bone-extending bracket involved in the present invention in combination with preferred embodiments and accompanying drawings.

[0043] see figure 1 As shown, one embodiment of the present invention provides a bone extension bracket, which includes a first link assembly 1, a front-end transfer slider assembly 2, a middle-end transfer slider assembly 3, a second link assembly 4, The tail end rotates the slider assembly 5 and the guide rail 6 .

[0044] The guide rail 6 is the main support, and the front transfer slider assembly 2 , the middle transfer slider assembly 3 and the tail rotation slider assembly 5 are connected together by screws 7 . Through the trapezoidal groove 6-1 on the guide rail 6 (as Image 6 shown) with the protruding trapezoidal features 2-4, 3-4 on each of the slider assemblies (such as figure 2 shown) cooperate to realize the limit in the direction of rot...

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 gradually increasing, which makes the medical conditions continue to improve and promotes the development of medical devices. [0003] For example, taking bone lengthening surgery as an example, bone lengthening brackets are usually used in order to fix broken bones. [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 joint activity is small or the rotation angle is small, the adjustment is not accurate, the overall weight is large, and the use is difficult. [0005] Therefore, it...
