Pre-loaded Suture Anchor Piercing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for attaching soft tissue to bone require numerous steps and the use of external instruments to pass sutures through tissue, increasing complexity and risk during fixation procedures.
Innovation Solution
A suture anchor with pre-loaded piercing structures and sutures that can be secured to the anchor body, allowing for direct piercing and securing of soft tissue to bone without the need for additional surgical instruments, reducing the number of steps and simplifying the fixation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional suture attachment methods using external instruments are used, then the suture can be passed through tissue, but the number of steps and operating time increase significantly
Solution Approach 1:
The patent combines the suture anchor, piercing structure, and suture into a single integrated device. The piercing structure is pre-loaded within the anchor body, and the suture is pre-attached to the piercing structure, eliminating the need for separate instruments and multiple sequential steps to pass suture through tissue.
Solution Approach 2:
The piercing structure and suture are prepared and positioned within the anchor body before the fixation procedure. This pre-assembly allows the surgeon to simply insert the anchor and automatically pierce the tissue with the pre-positioned structure, rather than performing multiple manual steps during surgery.
2Reliability
If external instruments such as lasso are used to pass suture through soft tissue, then the suture can be secured, but the device complexity and procedural risk increase
Solution Approach 1:
The patent merges the function of the suture anchor with the piercing structure and suture into one device. Instead of using separate instruments like lasso to pass suture through tissue, the anchor itself contains the piercing structure that directly pierces the tissue and secures the suture in a single integrated action.
3Ease of manufacture
If multiple sequential steps are used to secure suture anchor and pass suture, then the fixation can be achieved, but the procedural complexity increases
Solution Approach 1:
The piercing structure is pre-loaded within the anchor body and the suture is pre-attached to the piercing structure before the surgical procedure. This preliminary preparation eliminates the need for multiple sequential steps during surgery, as the anchor is inserted and the piercing structure automatically pierces the tissue with the suture already in position.

AI summary
A suture anchor is described. The suture anchor includes an elongate anchor body having a proximal end and a distal end, at least one suture secured within the anchor body, and at least one piercing structure secured within the body extending proximally out of the proximal end of the body, wherein the at least one piercing structure is engaged with the at least one suture. A method of attaching soft tissue to bone in a subject is also described. The method includes the steps of securing an anchor device into a bore formed in the bone, the anchor device comprising an anchor body and at least one pre-loaded piercing structure with at least one suture attached to both the anchor body and the piercing structure, piercing a soft tissue by forcing the at least one piercing structure through the soft tissue, such that at least a portion of the at least one suture passes through the soft tissue, and tying the at least one suture against the soft tissue to secure the soft tissue to the bone.
