Adaptive Blood Vessel Coagulation via Pressure Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy treatment systems face challenges in effectively managing blood vessel coagulation, particularly in varying blood pressure conditions, as they lack adaptive control mechanisms to adjust energy output and grasping force in response to blood pressure thresholds.
Innovation Solution
The system incorporates a processor-controlled energy treatment instrument with adjustable energy output modes and grasping force, using a measurement section to assess blood pressure and switch between coagulation modes and adjust grasping force based on threshold values, ensuring optimal coagulation performance regardless of blood pressure levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed energy output mode is used for blood vessel coagulation, then the device structure is simple, but the coagulation effectiveness varies under different blood pressure conditions
Solution Approach 1:
The energy treatment instrument provides multiple energy output modes (first mode and second mode) that can be dynamically switched based on blood pressure measurements. The processor selects the appropriate mode according to whether blood pressure is above or below a threshold value, making the system adaptive rather than fixed.
Solution Approach 2:
The system incorporates a measurement section that measures blood pressure and feeds this information back to the processor. The processor then adjusts the energy output mode based on the measured blood pressure, creating a closed-loop feedback control system that optimizes coagulation effectiveness.
2Reliability
If the grasping force is increased to maintain sealing at high blood pressure, then sealing performance is maintained, but the risk of tissue damage increases
Solution Approach 1:
The system changes the energy output parameters (switching between first and second modes) based on blood pressure measurements. At high blood pressure, the system switches to the second mode with different energy parameters that are optimized for high-pressure conditions, rather than simply increasing grasping force.
3Adaptability or versatility
If multiple energy output modes are implemented to adapt to different blood pressure conditions, then coagulation effectiveness is improved, but the device complexity increases
Solution Approach 1:
The measurement section continuously monitors blood pressure and provides feedback to the processor, which automatically selects the appropriate energy output mode. This feedback mechanism enables the system to adapt to different blood pressure conditions without requiring manual intervention or complex programming.
Solution Approach 2:
The system performs self-adjustment by automatically switching between energy modes based on real-time blood pressure measurements. The processor autonomously determines the appropriate mode without external control, making the system self-regulating and reducing the need for complex external control mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enhances the system's ability to consistently achieve effective blood vessel coagulation by adapting energy output and grasping force in response to blood pressure, maintaining sealing performance even at higher pressures.
Implementation Method 1
When electric energy is supplied to both electrodes, a high-frequency current flows between the electrodes through the grasped treatment target. The high-frequency current is thereby applied as treatment energy to the treatment target.
Data Source
AI summary
In a treatment system, an energy treatment instrument includes a pair of grasping pieces. An energy output source outputs electric energy to the energy treatment instrument, thereby applying treatment energy to a blood vessel grasped between the grasping pieces. A measurement section measures a blood pressure at a site related to the grasped blood vessel. A processor controls output of the electric energy from the energy output source based on a measurement result obtained by the measurement section, and thereby switches an actuation state of the energy treatment instrument between a first mode for coagulating the blood vessel and a second mode for coagulating the blood vessel target that is different from the first mode.
