Soft Tissue Anchor Delivery Device for Pelvic Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sutures are challenging to use in constrained or hard-to-reach surgical sites, such as those encountered in pelvic procedures, where manual placement and tying are difficult, leading to suboptimal tissue-to-tissue or tissue-to-implant connections.
Innovation Solution
A soft tissue anchor delivery device with a proximal handle and elongate shaft, featuring a magazine and ejector mechanism to deploy soft tissue anchors with elongate legs and a tie, allowing secure attachment of implants to pelvic tissue through minimally invasive procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional sutures are used for tissue connection, then the surgeon has manual control over placement and tying, but the procedure becomes time-consuming and difficult in constrained or hard-to-reach surgical sites
Solution Approach 1:
The patent replaces the manual mechanical suture tying system with an automated delivery device that uses mechanical mechanisms (ejector, magazine, shaft) to automatically place tissue anchors and secure tissue connections, eliminating the need for manual knot tying while maintaining surgical control
Solution Approach 2:
The patent introduces a delivery device as an intermediary between the surgeon and the tissue connection process. This device includes a shaft, magazine, and ejector mechanism that mediate the placement of tissue anchors, making the procedure easier and faster particularly in constrained surgical sites
2Manufacturing precision
If manual suture tying is performed by the surgeon, then precise control over knot placement is achieved, but the procedure becomes complex and difficult in tight or deep surgical access paths
Solution Approach 1:
The patent replaces the complex manual suture tying mechanism with a simplified automated delivery system that uses a shaft, magazine, and ejector to precisely place tissue anchors without requiring manual knot manipulation, reducing procedural complexity while maintaining placement precision
Solution Approach 2:
The patent extracts the complex knot-tying function from the surgical procedure by using a pre-formed tissue anchor with integrated securing features. The anchor is designed to be inserted and secured without manual knot manipulation, removing the complex tying step from the surgical workflow
3Reliability
If soft tissue anchors with elongate legs and tie are used, then secure attachment of implants to tissue is achieved, but the device structure becomes more complex compared to conventional sutures
Solution Approach 1:
The patent merges multiple functions into a single tissue anchor component: the elongate legs provide insertion and anchoring capability while the integrated tie provides secure attachment. This consolidation eliminates the need for separate sutures and knots, improving reliability while the overall system complexity is managed through the automated delivery device
