Multi-Blade Surgical Instrument for Single-Pass Osteotomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical cutting instruments require multiple cuts and passes to achieve a desired osteotomy shape, leading to inconsistencies and inefficiencies in osteotomy procedures.
Innovation Solution
Surgical instruments with multiple columns and/or rows of cutting blades on a single surface, designed to perform a wedge-shaped osteotomy in a single cut, utilizing materials like stainless steel and featuring varying blade shapes and configurations for precise bone cutting.
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 cuts and passes required
Solution Approach 1:
The surgical instrument divides the cutting function into multiple independent cutting blades arranged in rows and columns on a single surface. Each blade can be independently positioned and configured to perform specific cutting tasks, allowing complex osteotomy shapes to be achieved in a single pass without requiring multiple instrument changes or passes.
Solution Approach 2:
The invention transitions from traditional single-line cutting to a two-dimensional array of cutting blades arranged in rows and columns. This dimensional expansion allows simultaneous multi-point cutting across the bone surface, transforming a sequential single-pass process into a parallel multi-point operation that achieves complex shapes in one pass.
2Manufacturing precision
If multiple cuts and passes are performed with traditional instruments, then the device complexity remains simple, but the manufacturing precision of osteotomy shape and size is reduced due to inconsistencies
Solution Approach 1:
By segmenting the cutting function across multiple blades in rows and columns, each blade contributes to a specific portion of the final osteotomy shape. This segmentation allows precise control over the overall shape and size, ensuring consistency and accuracy that cannot be achieved with sequential single-line cutting.
Solution Approach 2:
The invention merges multiple cutting actions into a single coordinated pass by positioning multiple cutting blades simultaneously on the instrument surface. All blades operate together in one pass to create the complete osteotomy shape, eliminating the cumulative errors and inconsistencies that arise from multiple separate cuts and passes.
3Loss of time
If traditional surgical instruments perform multiple cuts, then the device structure is simple, but the loss of time increases due to repeated passes
Solution Approach 1:
The transition to a two-dimensional array of cutting blades enables parallel processing of the cutting task. Multiple blades operating simultaneously across the bone surface in rows and columns accomplish in one pass what would traditionally require multiple sequential passes, dramatically reducing procedural time.
Solution Approach 2:
The instrument maintains continuous cutting action across the entire osteotomy site by positioning multiple blades that operate simultaneously throughout the single pass. This eliminates the interruptions and repositioning required in traditional multi-pass methods, ensuring uninterrupted cutting that reduces overall procedural time.
