Solution Overview
Problem
Current hysteroscopic treatment systems face challenges in providing an efficient and reliable method for endoscopic viewing, fluid management, and tissue resection during procedures like uterine polyp removal, particularly in maintaining set pressure and fluid flow during high-speed cutting operations.
Innovation Solution
An integrated hysteroscopic treatment system comprising an endoscopic viewing system with a re-usable handle and disposable endoscope component, a fluid management system with peristaltic pumps and pressure sensing, and a resection device with a motor-driven cutting component, all controlled by a base unit with integrated software algorithms to manage fluid flow and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-speed cutting operations are performed during hysteroscopic procedures, then productivity is improved, but fluid management and pressure control become more difficult
Solution Approach 1:
The patent combines the fluid management system and pressure control system into an integrated system that operates simultaneously with the high-speed cutting device. The base unit coordinates fluid flow through peristaltic pumps while maintaining pressure through sensors and control algorithms, allowing both functions to work together during high-speed resection without interference.
Solution Approach 2:
The system employs pressure sensors that continuously monitor intrauterine pressure and provide feedback to the control system. The control algorithms process this feedback information and automatically adjust fluid flow rates and pump speeds to maintain the set pressure even during high-speed cutting operations, ensuring stable conditions throughout the procedure.
2Reliability
If integrated control systems are implemented, then reliability is improved, but device complexity increases
Solution Approach 1:
The control algorithms for fluid management, pressure control, and cutting operation coordination are merged into a single integrated base unit. This centralization allows the system to manage multiple functions through one coordinated control system rather than separate independent systems, improving reliability while managing complexity through integration.
Solution Approach 2:
The base unit is designed as a multi-functional device that handles fluid delivery, fluid return, pressure monitoring, pressure control, and cutting operation coordination all through one system. This universal design allows a single device to perform multiple functions that would otherwise require separate equipment, improving system coordination while containing complexity within one integrated platform.
