Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue dissecting and modifying devices face challenges in accurately tracking movement within the body and delivering energy to tissues with varying sensitivity, especially when used in minimally invasive surgeries, due to limitations in detecting tissue patterns and movement accuracy, particularly on fatty undersurfaces.
Innovation Solution
The development of a modular tissue dissector and modifier with non-axial protrusions and lysing elements, integrated with energy windows and sensors, such as temperature and motion sensors, allows for precise tissue separation and modification, including spot coagulation, while a feedback loop adjusts energy delivery based on real-time tissue conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional tissue dissecting devices are used, then tissue separation can be achieved, but movement tracking accuracy is insufficient and energy delivery precision is compromised
Solution Approach 1:
The device tip is segmented into multiple protrusions (at least three) arranged in a circular pattern, with lysing elements positioned between adjacent protrusions. This segmentation allows the device to interact with tissue at multiple discrete points simultaneously, improving movement tracking accuracy and energy delivery precision while maintaining manageable structural complexity through modular design
Solution Approach 2:
The lysing elements are nested within recesses in the tip structure, positioned between the protrusions. This nesting arrangement allows the lysing elements to be integrated into the tip without increasing overall device complexity, while enabling precise energy delivery to specific tissue locations through the coordinated action of the protrusions and lysing elements
2Reliability
If energy is delivered to tissues with varying sensitivity, then treatment effectiveness is improved, but risk of excess energy delivery increases
Solution Approach 1:
Sensors are integrated into the device to detect tissue conditions in real-time and provide feedback to a control system. This feedback mechanism enables the control system to adjust energy delivery dynamically based on tissue sensitivity, improving both safety by preventing excess energy delivery and adaptability by allowing tailored treatment to different tissue types
Solution Approach 2:
The device incorporates dynamic control of energy delivery through real-time sensor feedback, allowing the energy parameters to be adjusted during the procedure based on actual tissue response. This dynamic adaptation enables safe and effective treatment of tissues with varying sensitivity without requiring manual intervention or pre-programming for different tissue types
3Manufacturing precision
If sensors and feedback loops are integrated, then energy delivery precision is improved, but device complexity increases
Solution Approach 1:
The sensors, lysing elements, and control circuitry are merged into an integrated assembly that functions as a unified system. This merging approach improves energy delivery precision through coordinated operation of all components while managing device complexity by treating the sensor-feedback-loop as an integrated subsystem rather than separate elements
