Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If therapeutic energy is delivered to tissue without real-time monitoring and dynamic adjustment, then the treatment process is simple and fast, but treatment precision and consistency deteriorate
Solution Approach 1:
The system continuously monitors tissue properties (impedance, temperature, mechanical properties) during treatment and uses this feedback to dynamically adjust treatment parameters. The control system switches between first phase (energy delivery) and second phase (staple deployment) based on real-time tissue property measurements, ensuring precise and consistent treatment outcomes.
Solution Approach 2:
The treatment protocol transitions from static pre-programmed parameters to dynamic real-time adjustment. The system adapts treatment parameters based on measured tissue properties, switching between different treatment phases and adjusting energy delivery parameters dynamically during the procedure to optimize treatment precision.
2Reliability
If treatment parameters are fixed without real-time adjustment, then the device operation is simple, but treatment effectiveness and consistency worsen
Solution Approach 1:
The system performs self-adjustment by automatically monitoring tissue properties and modifying treatment parameters without requiring constant manual intervention. The control system autonomously switches between treatment phases and adjusts parameters based on real-time feedback, improving reliability while maintaining ease of operation through automated decision-making.
Solution Approach 2:
The system dynamically changes treatment parameters (energy level, pulse duration, treatment phase timing) based on measured tissue properties. This adaptive parameter adjustment ensures consistent and effective treatment outcomes by responding to actual tissue conditions rather than relying on fixed pre-set parameters.
3Adaptability or versatility
If phase switching is based solely on predetermined time thresholds, then the control logic is simple, but adaptability to varying tissue properties deteriorates
Solution Approach 1:
Phase switching decisions are based on real-time feedback from tissue property measurements rather than solely on predetermined time thresholds. The control system monitors tissue impedance, temperature, and mechanical properties during treatment and uses this information to determine the optimal timing for switching between first phase (energy delivery) and second phase (staple deployment), enhancing adaptability to varying tissue characteristics.

AI summary
A method for treating tissue using a surgical instrument including at least one electrode and a staple cartridge is disclosed. The method includes causing the at least one electrode to deliver a therapeutic energy to the tissue in a first phase of a surgical treatment by the surgical instrument, deploying staples from the staple cartridge into the tissue in a second phase of the surgical treatment, monitoring a first tissue property in the first phase of the surgical treatment, switching from the first phase to the second phase if at least one of two conditions is met, setting a parameter of the second phase of the surgical treatment based on at least one measurement of the first tissue property determined in the first phase of the surgical treatment, and monitoring a second tissue property, different from the first tissue property, in the second phase of the surgical treatment.
