Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time monitoring and dynamic parameter adjustment are implemented, then treatment precision is improved, but device complexity increases
Solution Approach 1:
The surgical instrument incorporates tissue property sensors that continuously monitor tissue characteristics during treatment and feed this information back to the control system. The control system then dynamically adjusts treatment parameters (energy delivery, staple deployment timing) based on the real-time tissue property measurements, creating a closed-loop feedback system that improves treatment precision while managing device complexity through automated control
Solution Approach 2:
The system transitions from static, pre-programmed treatment parameters to dynamic parameter adjustment based on real-time tissue property measurements. The control system continuously adapts treatment parameters during the surgical procedure, allowing the instrument to respond to varying tissue conditions and achieve more precise treatment outcomes
2Reliability
If multiple treatment phases with monitoring are implemented, then treatment effectiveness is improved, but treatment time increases
Solution Approach 1:
The system performs preliminary monitoring of tissue properties during the first treatment phase to assess tissue response before proceeding to the second phase. By evaluating tissue properties in advance, the control system can determine whether to continue, modify, or terminate treatment, ensuring effectiveness while avoiding unnecessary treatment time
Solution Approach 2:
The treatment is divided into discrete phases with periodic monitoring of tissue properties. The control system evaluates tissue response at predetermined intervals and transitions between phases based on measured thresholds or time limits, structuring the treatment to balance effectiveness with time efficiency
3Adaptability or versatility
If phase switching based on tissue property thresholds is implemented, then adaptability to tissue conditions is improved, but measurement precision requirements increase
Solution Approach 1:
The control system uses feedback from tissue property measurements to determine when to switch between treatment phases. Predetermined thresholds for tissue properties (such as impedance, temperature, or mechanical properties) trigger automatic phase transitions, enabling the system to adapt to different tissue conditions while relying on automated threshold comparison rather than continuous complex analysis
Solution Approach 2:
The system monitors changes in tissue properties (electrical, thermal, mechanical parameters) and uses these parameter changes to determine phase transitions. By establishing predetermined threshold values for key parameters, the system achieves adaptability to varying tissue conditions while maintaining manageable measurement precision requirements through threshold-based decision-making

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 delivering a therapeutic energy to the tissue in consecutive treatment zones, deploying staples from the staple cartridge into the tissue, detecting a parameter indicative of a progress of the staple deployment from the staple cartridge in the consecutive treatment zones, and sequentially deactivating electrodes to sequentially seize the delivery of the therapeutic energy to the tissue in the consecutive treatment zones based on the progress of staple deployment from the staple cartridge.
