Prosthesis Delivery System With Independent Needle Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue repair methods lack precision and control in delivering and implanting closure prostheses, requiring manual tying or knotting of integrated stitches, which is laborious and inefficient.
Innovation Solution
A prosthesis delivery and implantation system comprising a delivery cannula, first and second delivery needles, and impact members that transfer forces to the prosthesis ends, allowing for precise implantation of the prosthesis into tissue, with the option for simultaneous or independent movement of the impact members to enhance control and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual tying or knotting of integrated stitches is used, then the prosthesis can be implanted into tissue, but the procedure becomes laborious and time-consuming
Solution Approach 1:
The prosthesis is divided into multiple segments including a first end portion, a second end portion, and a central portion. Each end portion can be implanted independently through separate delivery needles, allowing parallel processing and eliminating the need for manual tying or knotting operations.
Solution Approach 2:
The prosthesis ends are pre-loaded into separate delivery needles before the implantation procedure begins. This preliminary preparation allows the surgeon to simply advance the needles to deliver the prosthesis segments in the correct positions without performing complex manual operations during the procedure.
2Measurement precision
If two ends of a closure prosthesis are inserted simultaneously, then the prosthesis is stapled into place, but precision in delivery and control of implantation is reduced
Solution Approach 1:
The prosthesis delivery system is segmented into separate delivery needles for each end portion. This segmentation allows independent control and precise positioning of each prosthesis end, enabling the surgeon to implant the first end portion and second end portion separately with high precision rather than simultaneously with reduced control.
3Reliability
If integrated stitches are used, then the prosthesis can be secured to tissue, but the manual tying or knotting process is laborious
Solution Approach 1:
The complex manual tying or knotting operation is extracted from the implantation process. Instead of requiring the surgeon to manually tie stitches, the system uses separate delivery needles to independently implant prosthesis end portions that achieve secure anchoring through their design and placement, eliminating the laborious manual knotting step while maintaining reliability.
