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

VSEngineering 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

Engineering Contradiction:
Improvecutting speedVSAvoidpressure control
Core Design Contradiction:
ProductivityVSReliability

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #23Feedback

2Reliability

If integrated control systems are implemented, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesystem coordinationVSAvoidcontrol system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
