Universal Osteotomy Device Saw Blade Guide and Barrier Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current osteotomy devices lack the ability to accurately and rapidly determine the cutting position, direction, and depth during high tibial osteotomy, often requiring preoperative evaluation and being unsuitable for urgent surgeries due to complex manufacturing processes and inability to non-invasively assess correction angles, leading to potential over-cutting and inefficiencies.
Innovation Solution
A universal osteotomy device with a first and second body component guiding a saw blade, featuring an in-vitro alignment component with engaging members and aiming holes for precise angle assessment and fixation, and an extended barrier plate to prevent over-cutting, allowing for immediate use in emergency situations with simplified manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a customized osteotomy device is designed according to patient needs, then measurement precision and adaptability are improved, but device complexity and manufacturing time increase
Solution Approach 1:
The patent applies universality by designing a standardized osteotomy device with fixed geometric parameters that can be used across multiple patients without customization. The device incorporates multiple guide edges and slots that can accommodate various cutting configurations, making it a multi-functional tool that maintains precision while eliminating custom manufacturing delays
Solution Approach 2:
The device embodies preliminary action through its pre-designed guide edges, slots, and barrier plates that are manufactured in advance with optimal geometric parameters. These pre-configured features allow surgeons to perform accurate osteotomies immediately without requiring preoperative customization or complex setup procedures
2Manufacturing precision
If preoperative evaluation and complex devices are used, then cutting precision is improved, but ease of operation and surgical efficiency deteriorate
Solution Approach 1:
The device is segmented into distinct functional components: guide edges for positioning, guide slots for saw blade alignment, barrier plates for depth control, and engagement features for fixation. This segmentation allows each component to perform its specific function independently, simplifying the overall operation while maintaining high cutting precision through the coordinated action of these specialized elements
Solution Approach 2:
The device implements self-service through its self-aligning guide slots and self-limiting barrier plates that automatically control cutting depth and direction without requiring complex preoperative planning or continuous surgeon adjustment. The geometric features guide the saw blade and prevent over-cutting autonomously, reducing surgical complexity while ensuring manufacturing precision
3Ease of manufacture
If a rigid fixed-geometry device is used, then manufacturing simplicity is improved, but adaptability to different patient needs deteriorates
Solution Approach 1:
The device addresses adaptability through dimensional design rather than geometric customization. By incorporating multiple guide edges at different orientations and multiple guide slots at various positions, the standardized device can accommodate different osteotomy requirements across patients. The barrier plates provide depth control in the vertical dimension while guide edges control horizontal positioning, achieving versatility through spatial arrangement rather than custom geometry

AI summary
The present invention provides a universal osteotomy device comprising a first body component and a second body component. The first body component has an upper guide edge for forming a cutting track. The second body component has a lower guide edge disposed below the upper guide edge. A guide slot is formed between the upper guide edge and the lower guide edge for guiding the saw blade to cut. The guide slot has a connecting member for connecting the upper guide edge and the lower guide edge. The surface of the first body component and the surface of the second body component have an average curvature of the bone surface.
