Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abdominal wall closure methods face challenges in normalizing retracted hernia edges, preventing fascial dehiscence, and avoiding complications associated with mesh reinforcement, while ensuring safe and effective wound management.
Innovation Solution
A tissue anchoring assembly using bioabsorbable anchors and magnetic distraction to restore near-normal anatomy, avoiding intraperitoneal segments and distributing tension across multiple points, with removable magnetic components and adjustable force control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mesh reinforcement is used to prevent hernia formation, then closure strength is improved, but complications such as visceral injury and long-term issues increase
Solution Approach 1:
The patent removes mesh from the abdominal wall closure system entirely, extracting the harmful element that causes visceral injury and long-term complications while maintaining closure strength through alternative means (tissue anchors and sutures).
Solution Approach 2:
The patent employs bioabsorbable tissue anchors that temporarily provide closure strength and then naturally degrade and absorb, eliminating the need for permanent foreign materials like mesh and avoiding long-term complications associated with implantable components.
2Reliability
If large retention sutures are used to hold abdominal wall in position, then prevention of dehiscence is improved, but tissue cutting and nerve injury increase
Solution Approach 1:
The patent uses small, distributed tissue anchors placed at specific locations rather than large retention sutures, concentrating the anchoring function at discrete points to minimize overall tissue trauma and nerve involvement while maintaining closure reliability.
Solution Approach 2:
The patent divides the closure system into multiple discrete tissue anchors distributed along the incision line, replacing the single continuous suture structure. This segmentation allows each anchor to independently secure tissue without requiring large loops that could cut through tissue or injure nerves.
3Stability of the object's composition
If intraperitoneal segments are used in closure devices, then closure stability is improved, but risk to underlying viscera increases
Solution Approach 1:
The patent removes intraperitoneal segments from the closure device design entirely, extracting the component that provides stability through abdominal wall penetration and replaces it with extraperitoneal tissue anchors that secure fascia and muscle without entering the peritoneal cavity, thereby eliminating direct threat to viscera.
4Manufacturing precision
If magnetic distraction is used to restore abdominal wall anatomy, then tissue approximation is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical distraction mechanisms with a magnetic field-based system. Magnets placed on the abdominal surface provide distributed approximation force without requiring mechanical linkages, actuators, or complex mechanical structures, thereby reducing device complexity while maintaining precision.
