Tendon Fixation Plate Wobble Joint Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for fixing tissue to bone in surgical procedures are time-consuming, costly, and prone to instability, requiring precise placement and often necessitating repeat interventions due to the size and complexity of existing implants, which can lead to necrotic processes and increased patient strain.
Innovation Solution
A novel implant design featuring a clamping surface with a large contact area, adjustable fastening means, and a wobble joint mechanism that allows for flexible orientation and minimally invasive insertion, along with barbs and conical fixing means to ensure secure attachment and promote blood flow, reducing the need for precise placement and minimizing necrotic risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implant is designed with a large contact surface and symmetric shape, then the stability and healing effectiveness are improved, but the implant size increases making minimally invasive surgery difficult
Solution Approach 1:
The implant is divided into two functional parts: a larger clamping surface component for stable tissue fixation and a separate smaller fastener for bone anchoring. This segmentation allows the clamping surface to be optimized for stability while the fastener minimizes insertion trauma, resolving the contradiction between fixation reliability and implant size for minimally invasive surgery.
2Reliability
If the implant requires precise placement with specific position, angle and orientation, then secure fixation is achieved, but the surgical time and costs increase
Solution Approach 1:
The fastener incorporates a wobble joint mechanism that transforms the rigid placement requirement into a dynamic adaptation process. During insertion, the wobble joint allows the fastener to self-align and adapt to varying bone surfaces and angles, eliminating the need for precise pre-planning of position and orientation while maintaining secure fixation.
Solution Approach 2:
The wobble joint enables the implant to self-align during insertion without requiring precise external positioning. The mechanism automatically adjusts the fastener's orientation to match the bone surface, allowing the implant to find its optimal position independently, thereby reducing surgical time and complexity.
3Reliability
If the implant is designed for secure fixation, then tissue stability is improved, but incorrect insertion can cause detachment requiring additional procedures
Solution Approach 1:
The wobble joint mechanism replaces the need for precise manual positioning with a mechanical self-alignment system. This substitution ensures that even if insertion角度 or position varies, the implant automatically adjusts to achieve proper alignment, preventing detachment and eliminating the need for corrective procedures.
4Stress or pressure
If the clamping surface has large contact area, then even contact pressure is achieved, but the implant complexity and handling difficulty increase
Solution Approach 1:
By separating the clamping surface from the fastening mechanism, the design allows the clamping surface to be simple and symmetric for easy handling, while the fastener contains the complex wobble joint mechanism. This segmentation maintains even contact pressure through the large clamping surface area without increasing overall device complexity or handling difficulty.
