Endoscopic Hernia Closure System with Integrated Fastener Pocket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current minimally invasive surgical techniques for hernia repair, such as laparoscopic and endoscopic procedures, face challenges in efficiently and effectively securing surgical meshes to tissue using fasteners like staples and tacks, which can be cumbersome and time-consuming.
Innovation Solution
A tissue defect closure system comprising an endoscopic surgical fixation device and an implant with a collapsible mesh fabric, where the implant has an elongated pocket to engage the device's outer tube, allowing for slidable contact and adjustable dimensions to accommodate different instruments, and a leash for tensioning, facilitating faster and more precise fastener placement across tissue defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical fasteners (staples, tacks, clips) are used to secure mesh to tissue in minimally invasive procedures, then tissue reinforcement is achieved, but the procedure becomes time-consuming and cumbersome
Solution Approach 1:
The patent combines the mesh implant and fastening mechanism into a single integrated system. The mesh includes integrated fasteners that are pre-attached to the mesh structure, allowing simultaneous deployment of both reinforcement and fixation in a single procedure step, eliminating the need for separate fastening operations
Solution Approach 2:
The fasteners are pre-attached to the mesh implant during manufacturing before the surgical procedure. This preliminary preparation allows the fasteners to be immediately ready for deployment without requiring additional assembly steps during the operation, thereby reducing procedural time
2Reliability
If multiple separate fasteners are applied manually through an instrument, then secure tissue attachment is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
Multiple fastening functions are merged into a single integrated fastener structure that is attached to the mesh as one unit. This eliminates the need to manually apply and position multiple separate fasteners, simplifying the surgical process while maintaining secure attachment
Solution Approach 2:
The mesh implant is designed with discrete, modular fastener units that can be independently positioned and deployed. This segmentation allows for simplified manual application while maintaining the integrity of the overall fastening system

AI summary
A tissue defect closure system includes an endoscopic surgical fixation device and an implant. The endoscopic surgical fixation device includes a handle assembly and an elongated outer tube having a distal end and including a plurality of fasteners disposed therein. The implant includes an elongated hollow body having a proximal end and a distal end, and defines an elongated pocket therein. The elongated pocket is dimensioned to engage the elongated outer tube of the endoscopic surgical fixation device.
