Multi-Guide Osteotomy Block for Faster Bunion Bone Realignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical procedures for correcting bunions require multiple cuts to the bone, necessitating frequent repositioning or switching of surgical cutting blocks, which is time-consuming and inefficient.
Innovation Solution
The development of osteotomy cutting systems and surgical techniques that allow for a surgical apparatus to be coupled to both the cuneiform and metatarsal bones, utilizing cutting blocks with multiple cut guides to facilitate efficient and precise bone realignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple surgical cutting blocks with single cutting guides are used for each cut, then cutting precision is maintained, but surgical procedure time increases and instrumentation efficiency decreases
Solution Approach 1:
The patent combines multiple single cutting guides into a single surgical cutting block that features multiple cutting guides simultaneously. This allows the surgeon to perform multiple cuts without changing blocks, directly resolving the contradiction by maintaining cutting precision through multiple guides while eliminating the time loss from repeated block repositioning or switching
Solution Approach 2:
The surgical cutting block is designed to perform multiple functions by incorporating multiple cutting guides that can accommodate different cut requirements. This multi-functional block serves as a universal tool for various osteotomy cuts during bunion correction, eliminating the need for multiple specialized blocks and improving both precision and efficiency
2Manufacturing precision
If multiple surgical cutting blocks are used for different cuts, then appropriate cutting guidance is achieved for each specific cut, but surgical instrumentation efficiency decreases
Solution Approach 1:
The patent merges multiple cutting guides into a single surgical cutting block, allowing the instrument to provide appropriate cutting guidance for multiple different cuts without requiring multiple separate blocks. This maintains the accuracy needed for each specific cut type while dramatically improving instrumentation efficiency by reducing the number of block changes required
Solution Approach 2:
The surgical cutting block is designed as a universal instrument that can accommodate multiple cutting guide configurations, enabling it to provide appropriate guidance for various osteotomy cuts. This multi-functionality allows a single block to replace multiple specialized blocks, improving productivity without sacrificing cutting guidance accuracy

AI summary
Osteotomy cutting systems and surgical methods are provided herein. One surgical method includes coupling, to a cuneiform of a subject, a surgical apparatus for use in facilitating correction of a bunion and coupling the surgical apparatus to another bone of the subject. Another surgical method includes coupling a surgical apparatus to a cuneiform and metatarsal of a subject, coupling a cutting block for alignment at a joint between the cuneiform and the metatarsal, and performing a surgical procedure utilizing the surgical apparatus and the cutting block to correct a bunion. A further surgical method includes providing a surgical apparatus for use in facilitating correction of a bunion in a subject in which the surgical apparatus is configured to couple to a cuneiform and a metatarsal of the subject and performing a surgical procedure utilizing the surgical apparatus while the surgical apparatus is coupled to the cuneiform and the metatarsal.
