Disposable Surgical Guide for Carpal Tunnel Tissue Expansion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tools for carpal tunnel syndrome treatment are cumbersome, require disinfection and sterilization, and present a learning curve for surgeons, while causing discomfort to patients, due to their non-disposable nature.
Innovation Solution
A disposable surgical guide with a round rod expander, integrated long column body, wing-shaped part, and limiting piece, equipped with a semi-cylinder, thread, elongated slot, and photo-taking element for precise tissue expansion and cutting, facilitating easier and more comfortable surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If commercially available surgical tools are used for carpal tunnel syndrome operation, then the surgeon can monitor the cutting position with light source, camera lens and display, but the devices require disinfection and sterilization before operation and present difficulty and learning curve
Solution Approach 1:
The patent employs a disposable surgical guide instrument that is discarded after a single use, eliminating the need for complex disinfection and sterilization procedures. The guide includes integrated features such as a long column body with elongated slot, wing-shaped part for positioning, and limiting piece to ensure precise cutting while maintaining simplicity and disposability.
2Measurement precision
If commercially available surgical tools are used for carpal tunnel syndrome operation, then the surgeon can see the actual cutting position during operation, but the procedure becomes more difficult and time-consuming due to sterilization requirements
Solution Approach 1:
The disposable nature of the surgical guide eliminates time-consuming sterilization preparation. The guide is pre-packaged and ready for immediate use, reducing preparation time while maintaining cutting precision through its integrated design features including the elongated slot for blade guidance and limiting piece for depth control.
3Measurement precision
If traditional surgical instruments are used for wrist tunnel syndrome, then the procedure can be performed with monitoring devices, but patient discomfort increases due to the complexity and non-disposable nature of the instruments
Solution Approach 1:
The disposable surgical guide reduces patient discomfort by eliminating the need for repeated sterilization processes that can cause delays and increase procedural complexity. The guide's simple design with integrated features (elongated slot, wing-shaped part, limiting piece) allows for precise surgery without the burden of complex monitoring device setup, thereby reducing overall patient discomfort.
4Reliability
If open or endoscopic surgery is performed to release the transverse ligament, then the median nerve pressure is relieved, but the procedure requires complex surgical techniques and monitoring equipment
Solution Approach 1:
The disposable surgical guide simplifies the surgical technique required for effective nerve pressure relief. The guide's integrated design features, including the elongated slot for precise blade positioning and the limiting piece for controlled ligament incision, enable reliable transverse ligament release without requiring complex endoscopic equipment or advanced surgical techniques, thereby maintaining effectiveness while reducing complexity.
