Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tendon suture methods lack standardization and flexibility, leading to variable results based on operator experience and are not suitable for small-space tendon repairs, with existing instruments being bulky and limiting in suture method selection.
Innovation Solution
A tendon suture instrument with a chamber and gripping element that includes wiring channels and needle guide holes, allowing for standardized operation and flexible suture methods, suitable for various tendon scenarios, including small-space repairs, by guiding suture wires through the tendon tissue using multiple needle guide holes and wiring channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tendon suture methods are used, then operator flexibility is maintained, but suture consistency and reliability deteriorate due to dependence on operator experience
Solution Approach 1:
The patent introduces a tendon clamp as an intermediary device that standardizes the suture process. The clamp includes pre-designed needle guide holes and wiring channels that guide the suture needle and wire through predetermined paths, eliminating variability caused by different operator techniques while maintaining ease of use through simple clamping and suturing operations
Solution Approach 2:
The patent changes the operational parameters by fixing the needle insertion angles, depths, and paths through the structured design of needle guide holes and wiring channels. This standardization transforms the variable operator-dependent process into a consistent procedure where parameters are determined by the device geometry rather than operator skill
2Reliability
If bulky tendon clamps are used, then suture stability is improved, but adaptability to small-space tendon repairs deteriorates
Solution Approach 1:
The tendon clamp is segmented into upper and lower clamping pieces that can be brought together to secure the tendon. This segmentation allows the clamp to be compact when closed, making it suitable for small surgical spaces, while still providing stable fixation during the suture procedure
Solution Approach 2:
The clamp design utilizes the vertical dimension by having clamping pieces that approach each other from opposite directions, allowing the tendon to be secured in a compact configuration that fits within limited surgical spaces while maintaining adequate clamping force for stability
3Manufacturing precision
If fixed needle guide hole designs are used, then suture method standardization is achieved, but versatility for different suture methods deteriorates
Solution Approach 1:
The tendon clamp is designed with multiple needle guide holes and various wiring channels (first, second, third, and fourth wiring channels) that can accommodate different suture techniques. This multi-functional design allows the same device to support standardized execution of multiple suture methods including cross-suture, figure-of-eight suture, and other variations

AI summary
Disclosed is a tendon suture instrument, including a chamber. One end of the chamber is provided with an opening, and the chamber is used for accommodating a sutured tendon tissue. The tendon tissue can enter the chamber through the opening of the chamber when needing to be sutured. The chamber is defined by a wall, and a first wiring channel and a first needle guide hole are arranged on the wall.
