Oblique Installation Pins for Bone Alignment Guide Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing guide modules for osteotomy procedures often fail to maintain proper alignment of bones due to parallel installation pins, leading to slippage and inadequate gap closure during the healing process.
Innovation Solution
A guide module with oblique installation pins, where the central axes of holes in the reposition guide and compression guide are spaced apart vertically, allowing the pins to penetrate at an angle and increase coupling force, thereby compressing the bone alignment site and enhancing fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parallel installation pins are used in the reposition guide, then the structure is simple and easy to manufacture, but the reposition guide slips off along the parallel pins and cannot properly maintain bone alignment
Solution Approach 1:
The patent applies asymmetry by changing the installation pins from a parallel arrangement to an oblique arrangement where the pins are not parallel to each other. The reposition guide includes multiple installation pins positioned at different angles relative to the bone surface, creating an asymmetric configuration that prevents slippage while maintaining reliable bone alignment during osteotomy procedures.
2Strength
If parallel installation pins are used, then the guide structure is simple, but the coupling force between the reposition guide and pins is insufficient
Solution Approach 1:
The installation pins are configured in an asymmetric oblique pattern rather than a symmetric parallel arrangement. This asymmetric configuration increases the coupling force between the reposition guide and the pins by distributing the load more effectively across different angles, preventing guide displacement while maintaining structural simplicity.
3Manufacturing precision
If parallel installation pins are used, then manufacturing is easy, but the gap between bones is not sufficiently decreased at the osteotomy site
Solution Approach 1:
The oblique asymmetric arrangement of installation pins enables better compression and gap closure at the osteotomy site. The pins are positioned at different angles to converge toward the gap area, applying compressive forces that effectively decrease the gap between bone segments during the healing process, while the manufacturing process remains straightforward.

AI summary
The present invention relates to a guide module having oblique installation pins, the guide module including: a first installation pin unit penetratively inserted into one side of an aligned bone; a second installation pin unit penetratively inserted into the other side of the aligned bone; a reposition guide unit simultaneously penetrated by the first installation pin unit and the second installation pin unit and being simultaneously in contact with one side of the aligned bone and the other side of the aligned bone; and a compression guide unit disposed adjacent to the reposition guide unit and simultaneously penetrated by the first installation pin unit and the second installation pin unit, in which imaginary central axes of holes of the reposition guide unit penetrated by the first installation pin unit and the second installation pin unit are spaced apart, at a predetermined interval in a vertical direction, from imaginary central axes of holes of the compression guide unit. Therefore, the aligned bone may be compressed.
