Multi-Actuating Trigger Anchor Delivery System for Minimally Invasive Tissue Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for Benign Prostatic Hyperplasia (BPH) and urinary incontinence often require invasive procedures, leading to significant discomfort, prolonged recovery times, and adverse effects, while minimally invasive methods provide limited relief and are associated with post-operative complications.
Innovation Solution
A multi-actuating trigger anchor delivery system that deploys anchor assemblies within the body to retract, lift, or reposition tissues, allowing for minimally invasive procedures with reduced trauma and discomfort, featuring a handle assembly with a rocker arm and spool mechanism for precise deployment and tensioning of anchor components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive surgical procedures are used to treat BPH and urinary incontinence, then effective tissue manipulation and repositioning can be achieved, but patient discomfort and recovery time increase significantly
Solution Approach 1:
The surgical procedure is divided into multiple discrete steps controlled by separate triggers: (1) deploying the needle assembly to the target site, (2) deploying the anchor assembly to engage tissue, and (3) retracting the needle assembly. This segmentation allows each step to be performed minimally invasively while maintaining overall procedural effectiveness for tissue manipulation.
2Reliability
If multiple anchor assemblies are deployed through separate incisions, then comprehensive tissue support can be achieved, but surgical complexity and recovery time increase
Solution Approach 1:
Multiple anchor assemblies are combined into a single integrated delivery system that can be inserted through one incision. The handle assembly contains multiple needle assemblies and anchor assemblies that are delivered sequentially through the same access point, reducing the number of incisions required while maintaining comprehensive tissue support coverage.
Solution Approach 2:
The delivery system is designed as a multi-functional device that can deploy multiple different anchor assemblies through a single handle assembly. The system universality allows one device to perform multiple functions (deploying various anchor types for different tissue support needs) through a single access point, simplifying the surgical procedure.
3Ease of operation
If traditional single-trigger mechanisms are used, then device operation is simple, but precise coordination of multiple deployment steps is difficult to achieve
Solution Approach 1:
The trigger mechanism is designed with dynamic, position-dependent functionality rather than a single static action. Each trigger pull advances the procedure to the next specific step (needle deployment, anchor deployment, needle retraction) based on the current state of the system. This dynamic approach maintains operational simplicity for the surgeon while achieving precise coordination of multiple deployment steps through state-based control.
