Medical Device With Movable Arms And Needle For Implant Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures for implanting devices in the pelvic region, such as sacrocolpopexy, require significant time and skill due to the need for multiple sutures and knots to secure implants, which can be cumbersome and inefficient.
Innovation Solution
A medical device featuring an elongate member with movable arms and a needle mechanism that allows for the precise placement and anchoring of tissue anchors within the body, facilitating the securement of implants by actuating the arms to grip tissue and the needle to insert anchors, thereby simplifying the attachment process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sutures and knots are used to secure implants, then the implant can be firmly attached to bodily tissue, but the procedural time and skill requirement increase significantly
Solution Approach 1:
The patent extracts the knot-tying function from the traditional suture process by using pre-tied surgical knots with integrated locking mechanisms. These extracted knot components can be independently deployed and secured without requiring the surgeon to perform multiple manual knot-tying operations, thereby reducing procedural time while maintaining secure implant attachment.
Solution Approach 2:
The surgical fixation system is segmented into distinct functional components: sutures, pre-tied knots, and locking mechanisms. This segmentation allows each component to be optimized independently and deployed in a controlled sequence, reducing the complexity and time of the overall attachment process while ensuring reliable fixation.
2Reliability
If multiple sutures and knots are used to secure implants, then the implant can be firmly attached to bodily tissue, but the procedural complexity and skill requirement increase
Solution Approach 1:
The patent merges multiple functions into integrated components: the surgical knot incorporates both the securing function and the locking function in a single device. This merging reduces procedural complexity by eliminating the need for separate knot-tying and locking steps, while maintaining reliable implant attachment through the combined mechanical advantage of both functions.
Solution Approach 2:
The surgical knots are designed with self-locking mechanisms that automatically secure the suture without requiring additional manual intervention. This self-service feature reduces procedural complexity by eliminating the need for surgeons to perform complex manual knot-tying operations, while ensuring reliable attachment through the self-securing mechanism.
3Reliability
If traditional suture methods are used to attach implants, then the implant can be secured to tissue, but the attachment process becomes cumbersome and inefficient
Solution Approach 1:
The surgical knots are pre-tied and pre-configured with locking mechanisms before being introduced to the surgical site. This preliminary preparation eliminates the need for complex intraoperative knot-tying maneuvers, making the attachment process easier to perform while ensuring reliable implant securation through the pre-engineered locking mechanism.
