Suture Guide and Anchor Driver for One-Handed Tissue Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical techniques for reattaching detached ligament and tendon to bone lack precision in positional and tension control, requiring multiple hands and prolonging surgical procedures.
Innovation Solution
A surgical tool with an integrated anchor driver and guide portion allows single-handed deployment of a suture guide and anchor, enabling precise positioning and fixation of soft tissue to bone using a cannular handle and detent mechanism, facilitating one-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional multi-handed surgical techniques are used for tissue fixation, then positional and tension control can be achieved, but procedure time increases and personnel requirements increase
Solution Approach 1:
The patent combines multiple functions (suture guide deployment, anchor deployment, tissue tensioning, and fixation) into a single integrated surgical tool that can be operated with one hand. The guide portion and anchor driver are integrated such that the guide portion can be deployed and then the anchor driver can be activated without requiring multiple separate instruments or multiple hands, thereby reducing procedure time while maintaining precision through the integrated mechanical design
Solution Approach 2:
The surgical tool is designed as a multi-functional device that performs suture guide placement, anchor deployment, and tissue fixation within a single instrument. The handle portion serves multiple purposes including guiding the suture, deploying the anchor, and maintaining tension control, eliminating the need for multiple specialized instruments and reducing the number of personnel required
2Reliability
If traditional surgical tools are used for tissue fixation, then fixation can be achieved, but the complexity of operation increases requiring multiple hands
Solution Approach 1:
The surgical tool is divided into distinct functional segments: a handle portion for operation, a guide portion for suture positioning, and an anchor driver for fixation. Each segment performs a specific function and can be independently optimized. The guide portion can be deployed and then retracted or discarded, allowing the anchor driver to be activated separately for fixation, simplifying the operational sequence while maintaining reliability
Solution Approach 2:
The integrated tool is designed to be self-sufficient, with all necessary components (suture guide, anchor, tensioning mechanism) included in a single device that can be operated autonomously with one hand. The tool includes built-in mechanisms for guiding the suture through tissue, deploying the anchor, and maintaining tension without requiring assistance from multiple surgeons or additional instruments
3Manufacturing precision
If multiple hands are required for tissue fixation, then precision control is improved, but device complexity and personnel requirements increase
Solution Approach 1:
The patent merges the functions of multiple hands into a single integrated tool by combining the guide portion and anchor driver in one device. The guide portion is designed to be deployable and then retractable or disposable, allowing the anchor driver to be activated without requiring a second hand, thereby reducing system complexity while maintaining positioning precision through the integrated mechanical design

AI summary
A surgical tool incorporates a suture guide with an anchor driver supporting an anchor where the anchor is maintained at a distance from the suture guide until release of a detent mechanism. Thereafter, the anchor is allowed to move into proximity to the suture guide, fixing a suture supported by the suture guide to a substrate, the entire procedure being achievable with a single hand.
