Insert Holding Device for Suture Attachment in Bone Implants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Attaching sutures to an insert for bone insertion is challenging, particularly in ligament repair procedures like ACL reconstruction, due to the small size of components involved and the importance of precise positioning for biological performance.
Innovation Solution
An insert holding device with recesses configured to hold and connect sutures around an insert, facilitating easy attachment by allowing a first suture to be laid around a second suture and the insert, enhancing the surgeon's ability to secure the suture to the insert with a knot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sutures are attached to an insert for bone insertion using conventional methods, then the surgical procedure can be completed, but the attachment process is challenging and time-consuming due to the small size of components
Solution Approach 1:
A holding device is introduced as an intermediary tool that temporarily holds the insert and facilitates suture attachment. The device includes a holding structure with recesses that receive the insert and guide sutures, making the attachment process easier and faster without directly modifying the insert or sutures themselves.
Solution Approach 2:
The holding device pre-positions the insert in a specific orientation within its holding structure, with recesses that guide the sutures into place before the actual knotting occurs. This preliminary arrangement of components simplifies the subsequent suture attachment steps.
2Manufacturing precision
If conventional suture attachment methods are used, then the procedure can be completed, but precise positioning of the insert is difficult to achieve
Solution Approach 1:
The holding device serves as a mediator that ensures precise positioning of the insert through its structured recesses and holding features, while simultaneously providing guidance for suture attachment. This intermediary tool resolves the conflict between precision and ease of operation.
Solution Approach 2:
The holding device has different regions with specific functions: a holding structure for secure insert positioning, recesses for suture guidance, and an open structure for knot formation. Each region is optimized for its specific function, enabling both precise positioning and easy attachment.
3Ease of operation
If a holding device with multiple recesses is used, then suture attachment is simplified, but the device complexity increases
Solution Approach 1:
The holding device is segmented into distinct functional regions: a holding structure for the insert, multiple recesses for different suture configurations, and an open area for knot formation. This segmentation allows each part to perform its specific function efficiently while keeping the overall design manageable.
Solution Approach 2:
The holding device is designed with multiple recesses that can accommodate different suture configurations and insert types, making it a universal tool that can handle various surgical scenarios without requiring multiple specialized devices, thus balancing complexity with versatility.
