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 involve invasive procedures with high risks of adverse effects, lengthy recovery times, and require hospital stays, while minimally invasive methods provide limited relief and are associated with post-operative discomfort and catheterization.
Innovation Solution
A multi-actuating trigger anchor delivery system that deploys anchor assemblies within the body to retract, lift, or compress 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 traditional invasive surgical procedures are used to treat BPH and urinary incontinence, then effective tissue manipulation and relief of symptoms can be achieved, but the procedures cause extensive trauma, require lengthy recovery times, and necessitate hospital stays
Solution Approach 1:
The patent replaces traditional invasive mechanical surgical instruments with a delivery system that uses a spool mechanism and guide wire to deploy anchors minimally invasively. The spool assembly winds and unwinds to advance the anchor along the guide wire through the body lumen, eliminating the need for extensive surgical incisions and direct mechanical manipulation of tissues.
Solution Approach 2:
The patent introduces a guide wire as an intermediary element that facilitates the delivery of the anchor assembly through the body lumen. The guide wire serves as a pathway that allows the anchor to be positioned and deployed at the target site without requiring direct access through large incisions, thereby reducing surgical trauma.
2Object-affected harmful factors
If minimally invasive methods are used to treat BPH and urinary incontinence, then surgical trauma is reduced, but the relief provided is limited and post-operative discomfort and catheterization are still required
Solution Approach 1:
The patent employs a dynamic deployment mechanism where the anchor assembly is advanced along the guide wire using a spool mechanism that can be controlled to deploy the anchor at the precise target location. The anchor is designed to expand or engage with the tissue dynamically upon deployment, ensuring effective symptom relief while maintaining minimal invasiveness throughout the procedure.
3Reliability
If traditional surgical procedures are performed, then complete treatment of BPH and urinary incontinence can be achieved, but extensive incisions and prolonged hospital stays are required
Solution Approach 1:
The patent segments the treatment procedure into distinct components: a delivery system with spool mechanism, a guide wire, and an anchor assembly. This segmentation allows each component to be optimized for its specific function, enabling the complete treatment to be achieved through a minimally invasive single-procedure approach that eliminates the need for prolonged hospital stays.
4Loss of time
If minimally invasive anchor delivery is used, then recovery time is reduced, but precise deployment and tensioning of anchor components become more challenging
Solution Approach 1:
The patent incorporates a ratchet mechanism that provides mechanical feedback during anchor deployment. The ratchet allows the spool to be advanced in controlled increments and prevents backward movement, ensuring precise positioning of the anchor at the target site. This feedback mechanism enables accurate deployment and tensioning of the anchor components while maintaining the benefits of minimally invasive surgery.
