Solution Overview
Problem
Existing treatment tools for biological tissues face challenges in managing the thickness of tissues during energy application, leading to potential tissue damage due to explosive steam generation when the thickness changes, which is not effectively monitored or controlled.
Innovation Solution
A treatment tool generator system that calculates a thickness index value of the biological tissue and adjusts the power supply and grasping force accordingly, using a processor to determine change timings and perform controls such as reducing or increasing power and grasping force to prevent tissue damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If treatment energy is continuously applied to biological tissue, then treatment effectiveness is improved, but tissue damage occurs due to explosive steam generation when thickness changes
Solution Approach 1:
The system continuously monitors tissue thickness during treatment and uses this feedback to dynamically adjust power supply. When thickness changes are detected, the system automatically reduces or suspends power to prevent explosive steam generation, while maintaining treatment effectiveness when thickness is stable.
Solution Approach 2:
The power supply is transformed from a static constant state to a dynamic adjustable state. The system continuously adapts power levels based on real-time tissue thickness conditions, switching between different power states (reducing, suspending, or maintaining) to match the changing tissue conditions during treatment.
2Reliability
If power is reduced or suspended to prevent steam explosion, then tissue safety is improved, but treatment efficiency decreases
Solution Approach 1:
The system applies treatment energy in controlled periodic cycles rather than continuously. When thickness changes indicate risk of steam explosion, power is temporarily suspended for a predetermined time period, then resumed when safe. This periodic on-off pattern prevents damage while maintaining overall treatment progress.
Solution Approach 2:
When tissue thickness changes are detected, the system quickly skips through the dangerous phase by suspending power for a predetermined time period, then rapidly resumes treatment. This allows the system to rush through the unsafe condition minimally and get back to effective treatment as quickly as possible.
3Manufacturing precision
If grasping force is increased to hold tissue during treatment, then treatment precision is improved, but tissue damage risk increases due to excessive force
Solution Approach 1:
The grasping force is transformed from a static constant state to a dynamic adjustable state. The system continuously adapts grasping force levels based on real-time tissue thickness conditions, increasing force when thickness is stable for precision, and reducing force when thickness changes to prevent damage.
Solution Approach 2:
The system changes the physical parameter of grasping force based on tissue conditions. When tissue thickness changes are detected, the system adjusts the grasping force parameter to appropriate levels, balancing the need for precision with the need to prevent force-induced damage.
4Reliability
If tissue thickness is monitored in real-time to prevent steam explosion, then treatment safety is improved, but system complexity increases
Solution Approach 1:
The system replaces complex mechanical thickness measurement devices with electrical impedance-based detection. By measuring changes in electrical properties of the tissue during treatment, the system infers thickness changes without requiring separate mechanical measurement systems, thus reducing overall system complexity.
