Transosseous Guide for Intersecting Bone Tunnel Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for transosseous attachment, such as attaching soft tissues to bones, face challenges in efficiently forming intersecting bone tunnels and passing sutures or other elements through these tunnels, especially in complex anatomical sites like the shoulder joint, requiring improved precision and ease of use.
Innovation Solution
A system comprising a guide body with adjustable guide axes and tunnel members that form intersecting bone tunnels, along with a passer that allows for a continuous path through these tunnels, facilitating the insertion and retrieval of sutures or other elements, enhancing the ease and precision of transosseous attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional surgical methods are used to form intersecting bone tunnels and pass sutures through them, then the surgical procedure can be completed, but the process is complex, time-consuming, and requires multiple separate steps
Solution Approach 1:
The patent combines multiple surgical functions into a single integrated guide body that can simultaneously form intersecting bone tunnels and guide suture passage. The guide body integrates tunnel formation capabilities with suture routing features, allowing surgeons to perform what previously required multiple separate instruments and steps in a single coordinated action, thereby improving surgical efficiency while managing complexity through integration.
Solution Approach 2:
The guide body is designed as a multi-functional instrument that can form bone tunnels, guide suture passage, and accommodate various suture types and configurations. This universal tool replaces multiple specialized instruments, allowing a single device to perform multiple surgical tasks that previously required separate devices, thus improving productivity without proportionally increasing device complexity.
2Loss of time
If traditional methods are used to pass sutures through bone tunnels, then the attachment can be formed, but the process requires multiple separate actions and increases surgical time
Solution Approach 1:
The guide body is pre-configured with specific geometric features, angles, and passage routes that anticipate the required suture trajectory through intersecting bone tunnels. By preparing the guidance structure in advance with built-in routing paths, the system eliminates the need for surgeons to manually navigate and adjust suture routes during the procedure, reducing surgical time while maintaining ease of operation through pre-planned geometric guidance.
3Manufacturing precision
If precise intersecting bone tunnels are formed using traditional methods, then accurate transosseous attachment is achieved, but the procedure becomes more complex and difficult to perform
Solution Approach 1:
The guide body serves as an intermediary instrument between the surgeon and the bone, providing a mechanical interface that translates simple surgeon actions into precise tunnel formation. The guide body's rigid structure and pre-configured geometry act as a mediator that ensures accurate tunnel angles and intersections without requiring the surgeon to manually calculate or measure complex spatial relationships, thereby maintaining precision while improving ease of operation.
