Surgical Instruments With Row-and-Column Blades for Wedge Osteotomy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical cutting instruments require multiple cuts and passes to achieve a desired osteotomy shape and size, leading to inconsistencies and inefficiencies in surgical procedures.
Innovation Solution
Surgical instruments with multiple columns and/or rows of cutting blades on a single surface, allowing for a wedge-shaped osteotomy to be performed in a single cut or pass, utilizing materials like stainless steel and designed with specific dimensions and angles to facilitate precise bone cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional surgical cutting instruments are used, then the surgical procedure can be performed, but multiple cuts and passes are required leading to increased time and inconsistency in osteotomy shape and size
Solution Approach 1:
The surgical instrument divides the cutting function into multiple independent cutting blades arranged in columns and rows. Each blade can make a separate cut, allowing the instrument to perform multiple cuts in a single pass through the bone, thereby eliminating the need for repeated passes and reducing surgical time while maintaining consistent osteotomy geometry.
Solution Approach 2:
The invention transitions from a single-cutting-edge instrument to a multi-blade configuration with blades arranged in multiple columns and rows across the instrument face. This dimensional expansion allows simultaneous engagement of multiple bone surfaces, enabling complex osteotomy shapes to be created in a single pass rather than requiring multiple sequential cuts.
2Reliability
If multiple cuts and passes are performed with traditional instruments, then the desired osteotomy can be approached, but inconsistencies in shape and size occur across different patients
Solution Approach 1:
The cutting function is segmented into multiple independent blades, each responsible for creating a specific portion of the osteotomy. This segmentation allows precise control over the final osteotomy geometry, ensuring consistent shape and size across different patients while distributing the cutting task across multiple specialized cutting elements.
Solution Approach 2:
The surgical instrument is designed with a universal multi-blade configuration that can create various osteotomy shapes and sizes by selectively engaging different combinations of blades. This multi-functional design allows a single instrument to reliably produce consistent results across different surgical scenarios and patient anatomies without requiring multiple specialized tools.
3Productivity
If traditional single-sided cutting instruments are used, then the instrument structure remains simple, but multiple passes are required reducing surgical efficiency
Solution Approach 1:
The cutting function is divided into multiple independent blades arranged in columns and rows, allowing the instrument to perform multiple cutting operations simultaneously in a single pass. This segmentation dramatically increases productivity by eliminating the need for repeated passes, though it does increase the structural complexity of the instrument.
Solution Approach 2:
Multiple cutting blades that would traditionally require separate instruments or multiple passes are merged into a single integrated surgical instrument. This combining of multiple cutting functions into one tool allows all necessary cuts to be made in a single pass through the bone, significantly improving surgical efficiency and productivity.
