Osteotomy Cutting Burrs and Blades for Single-Pass Bone Shaping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical cutting instruments require multiple cuts and passes to achieve a desired osteotomy shape and size, leading to inconsistency and inefficiency.
Innovation Solution
Surgical instruments with cutting burrs on one or both surfaces, designed to perform a wedge-shaped osteotomy in a single cut, utilizing a combination of cutting burrs and blades to ensure precision and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional single-sided surgical cutting instruments are used, then the device complexity is low, but the productivity is reduced due to multiple required cuts and passes
Solution Approach 1:
The patent combines multiple cutting functions (cutting burrs and cutting blades) into a single surgical instrument body with multiple surfaces, enabling the instrument to perform multiple cuts simultaneously during a single pass through the bone, thereby eliminating the need for multiple sequential passes required by traditional single-sided instruments
Solution Approach 2:
The instrument body is divided into multiple surfaces (first surface, second surface, third surface) with different cutting elements positioned on each surface, allowing different portions of the bone to be cut by different surfaces simultaneously or in sequence during a single operational pass
2Manufacturing precision
If multiple cuts and passes are performed with traditional instruments, then the device complexity remains simple, but the manufacturing precision deteriorates due to shape and size inconsistencies
Solution Approach 1:
By merging multiple cutting functions into one instrument with multiple surfaces, the patent ensures that all cuts are made in a single controlled pass, eliminating the cumulative errors and inconsistencies that arise from multiple separate cutting operations with traditional instruments
Solution Approach 2:
Different surfaces of the instrument body are equipped with different types of cutting elements (cutting burrs on first surface, cutting blades on second surface, additional cutting burrs on third surface) optimized for specific cutting tasks, ensuring precise and consistent cutting results for different portions of the bone structure
3Loss of time
If multiple cuts are performed to achieve desired osteotomy shape, then the ease of operation is maintained with simple instruments, but the loss of time increases significantly
Solution Approach 1:
The patent merges multiple cutting capabilities into a single operable unit that can be controlled by one surgical motion, reducing the time required for osteotomy while maintaining ease of operation through a unified control mechanism that manages all cutting surfaces simultaneously
