External Suture Anchor Assembly for Less Invasive Tissue Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical treatments for urinary incontinence, such as mesh or sling implants, are associated with complications like injury, bleeding, urinary tract infections, and chronic pain, necessitating the development of improved surgical methods for tissue repair.
Innovation Solution
A suture-based tissue-support system with an applicator device that deploys and anchors a suture device externally to target tissue, reducing invasiveness and increasing stability by positioning the anchor outside the tissue, using a needle to pass through the tissue and deploy the anchor externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh or sling implants are used for surgical repair, then tissue support is provided, but complications such as injury, bleeding, urinary tract infections, and chronic pain occur
Solution Approach 1:
The patent extracts the anchor from the tissue interior and positions it externally on the tissue surface. This eliminates the need for deep tissue penetration and internal anchoring, thereby reducing surgical complications such as injury, bleeding, and infections while maintaining effective tissue support through external anchoring and suture tension.
Solution Approach 2:
The surgical system is divided into separate functional components: an applicator device for deployment, a needle for tissue penetration, and an anchor for external fixation. This segmentation allows each component to perform its specific function efficiently, reducing overall surgical trauma and complication risks.
2Reliability
If conventional surgical approaches are used, then tissue repair is achieved, but invasiveness and discomfort increase
Solution Approach 1:
The anchor is extracted from the tissue interior and repositioned externally. This reduces the invasiveness of the procedure by minimizing the depth and extent of tissue penetration required, while still achieving effective tissue repair through external anchoring and suture tension.
3Stability of the object's composition
If anchors are positioned within tissue, then secure fixation is achieved, but tissue damage and recovery time increase
Solution Approach 1:
The anchor is extracted from the tissue interior and positioned externally on the tissue surface. This eliminates the need for deep tissue penetration and internal anchoring, thereby reducing tissue damage and associated complications while maintaining secure fixation through external anchoring and suture tension.
Solution Approach 2:
The needle creates a pilot channel through the tissue before the anchor is deployed. This preliminary action facilitates easier anchor insertion and reduces tissue resistance, minimizing tissue damage while ensuring proper anchor placement for stable fixation.
