Multi-Blade Osteotomy Instrument for Single-Pass Bone Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional single-sided surgical cutting instruments require multiple cuts and passes to achieve a desired osteotomy shape, leading to inconsistencies and inefficiencies in surgical procedures.
Innovation Solution
A surgical system with a body featuring multiple cutting blades on parallel surfaces, allowing for a single pass to perform osteotomies such as wedge-shaped, straight-cut, or parallel-cut osteotomies, and includes an attachment mechanism for coupling with a reciprocating saw.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional single-sided cutting device is used, then the device structure is simple, but multiple cuts and passes are required leading to increased surgical time and inconsistency
Solution Approach 1:
The patent combines multiple cutting blades on both sides of a single instrument body, allowing simultaneous cutting actions that were previously performed sequentially with separate tools. This merging of multiple cutting functions into one device enables completion of osteotomy in a single pass, directly improving surgical efficiency without requiring multiple separate instruments
Solution Approach 2:
The cutting device is segmented into multiple independent cutting blades arranged in columns on opposite surfaces of the instrument body. Each blade can be positioned at different heights and angles, allowing precise control over the cutting pattern while maintaining a unified instrument structure that performs multiple cutting functions simultaneously
2Manufacturing precision
If multiple cuts and passes are performed with traditional instruments, then the cutting process is thorough, but inconsistencies in shape and size occur across different patients
Solution Approach 1:
The cutting blades are pre-positioned at specific heights and angles relative to each other before the surgical procedure begins. This preliminary configuration ensures that when the instrument is applied, all cuts are made simultaneously with predetermined geometric relationships, eliminating the variability introduced by manual repositioning between multiple passes and ensuring consistent osteotomy shape across different patients
Solution Approach 2:
By combining multiple cutting blades into a single instrument that performs all necessary cuts in one pass, the patent eliminates the cumulative errors and variability that occur when multiple separate cutting actions are performed sequentially. The simultaneous cutting action ensures that the relative positions and angles of all cuts are maintained precisely, improving shape consistency
3Loss of time
If traditional single-sided cutting instruments are used, then the instrument design is straightforward, but more time is required to complete the osteotomy
Solution Approach 1:
The patent transitions from a single-sided cutting surface to a multi-surface configuration with blades on opposite sides of the instrument body. This dimensional expansion allows the instrument to perform cutting actions on both sides of the bone simultaneously, effectively doubling the productive output of the instrument and reducing the time required to complete the osteotomy despite the increased structural complexity
