Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hysteroscopic surgery equipment lacks coordinated interaction between distension, shaving, and suction functions, requiring manual control by the surgeon, which is inefficient and cumbersome.
Innovation Solution
A surgical system integrating a controller to coordinate a distension device, shaving device with a suction channel, and collection device, including a distension fluid collection system, negative pressure supply, and storage container, allowing automated control of fluid delivery, shaving, and waste removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate distension device and suction device are used, then each device can be optimized independently, but the system complexity increases and manual coordination is required
Solution Approach 1:
The patent combines the distension device and suction device into an integrated surgical system with a single controller that coordinates both functions. The controller manages the distension pump, suction pump, and various sensors as unified components, eliminating the need for separate device operation while maintaining individual device optimization through modular design.
Solution Approach 2:
The integrated surgical system performs multiple functions including distension, suction, pressure monitoring, and fluid level monitoring through a single multi-functional platform. The system can adapt between different surgical modes by coordinating the same hardware components for different purposes.
2Reliability
If separate distension device and suction device are used, then each device can be optimized independently, but manual control effort increases
Solution Approach 1:
The system incorporates pressure sensors that continuously monitor intrauterine pressure and provide feedback to the controller. The controller automatically adjusts the distension and suction operations based on this feedback, eliminating the need for manual coordination and reducing surgeon workload while maintaining safe operating parameters.
Solution Approach 2:
The controller automatically manages the coordination between distension and suction functions without requiring manual intervention. The system self-regulates by monitoring pressure levels and fluid dynamics, automatically adjusting pump operations to maintain optimal conditions throughout the surgical procedure.
3Ease of operation
If automated coordination is implemented, then manual control effort is reduced, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical coordination with an electronic control system that uses sensors, microprocessors, and automated algorithms to manage device operations. The controller electronically coordinates the distension pump, suction pump, and monitoring systems, substituting complex manual mechanical adjustments with automated electronic control.
4Productivity
If integrated system is used, then procedural efficiency is improved, but initial setup complexity increases
Solution Approach 1:
The system performs preliminary setup and calibration automatically during initialization. The controller pre-configures the coordination between distension and suction systems, and automatically calibrates sensors before the surgical procedure begins, reducing the complexity of manual setup while ensuring optimal performance.
