Arthroscopic Labrum Repair Tool Anchor Cassette
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current arthroscopic tools for hip reconstruction, particularly for labrum repair, face challenges in the deep and confined space of the hip joint, where delivering and controlling surgical instruments is difficult due to the joint's anatomy, and existing methods using sutures that encircle the labrum can cause trauma and hinder healing.
Innovation Solution
An arthroscopic tool with a cannulated working channel and an anchor cassette that allows anchors to be inserted through the labrum into the bone, using a suture that passes through the labrum instead of encircling it, facilitating easier healing and secure attachment without the need for frequent repositioning of the tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If sutures encircle the labrum for attachment, then secure fixation is achieved, but trauma to the labrum increases and healing is hindered
Solution Approach 1:
Instead of encircling the labrum with sutures (conventional approach), the patent inverts the approach by inserting anchors through the labrum from the articular surface side. The suture then passes through the anchor and attaches to the acetabular rim, effectively inverting the traditional attachment mechanism to reduce labral trauma while maintaining fixation strength
2Ease of operation
If traditional arthroscopic tools are used in the deep hip joint, then labrum repair can be performed, but control of the surgical instrument becomes difficult
Solution Approach 1:
The arthroscopic tool is segmented into multiple functional components: a shaft for insertion, a holding element with a concave surface for labrum engagement, and an anchor cassette mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall control from the proximal end, addressing the control difficulty in the deep hip joint
3Manufacturing precision
If frequent repositioning of the tool is performed, then accurate anchor placement is achieved, but procedure time increases
Solution Approach 1:
The holding element is designed with a concave surface that preliminarily positions and stabilizes the labrum before anchor insertion. This preliminary action ensures accurate anchor placement without requiring frequent repositioning during the procedure, thereby reducing procedure time while maintaining precision
