Knotless Suture Thread With Support Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suturing methods require time-consuming knotting procedures, especially in limited spaces during surgical operations, which can be challenging with laparoscopic or endoscopic tools, and existing surgical robots are expensive and not widely usable.
Innovation Solution
A suture thread system that includes a support body and/or needle accommodation body, allowing for knotless suturing by using a support body to prevent thread pull-through and a needle accommodation body that secures the thread, eliminating the need for manual knotting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suturing methods are used with manual knotting, then the suture can be securely tied, but the operation time increases significantly
Solution Approach 1:
The suture thread is pre-formed with a loop structure and support body during manufacturing, so that the knotting action is performed in advance rather than during the surgical procedure. This eliminates the time-consuming manual knotting step during surgery while maintaining secure suture fixation.
Solution Approach 2:
The suture thread structure is designed to be self-fixing through its pre-formed loop and support body configuration. The thread automatically maintains its secured state without requiring additional manual knotting operations, allowing the suture to secure itself during insertion.
2Reliability
If two tools are used to tie a knot during suturing, then the suture can be securely fastened, but the device complexity and space requirements increase
Solution Approach 1:
The knot-tying function is extracted from the surgical procedure and integrated into the suture thread structure itself. The pre-formed loop and support body eliminate the need for separate knot-tying tools, reducing device complexity from two tools to a single pre-configured suture thread.
Solution Approach 2:
The suture thread combines multiple functions into a single integrated structure: the thread itself, the loop formation, and the support body work together as one unified component, replacing the need for separate tools for thread manipulation and knot tying.
3Ease of operation
If surgical robots are used to facilitate suturing and knotting, then the ease of operation improves, but the cost and installation space increase significantly
Solution Approach 1:
The invention uses a simple, disposable suture thread with pre-formed loop structure instead of expensive, complex surgical robots. The low-cost suture thread provides the necessary functionality without requiring high-tech robotic systems, making the procedure accessible and cost-effective.
Solution Approach 2:
The complex mechanical robotic system is replaced with a simple pre-configured suture thread structure. The robotic manipulation function is substituted by the inherent structural design of the suture thread that requires minimal manipulation during surgery.

AI summary
A suture thread is used to perform suturing without tying part of or the whole of knots that are supposed to be tied during suturing. A suture thread support body prevents an end of the suture thread from being pulled into a suturing site. A needle accommodation body has a shape of a tube having a through-hole through both ends. The suture thread has the suture thread support body and the needle accommodation body.
