Rotating Cannula Implant Placement Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implant placement tools often result in harm and bruising due to restricted motion and excessive force required for inserting implants into tissue, particularly when dealing with different types of tissue, and lack precise control over implant depth.
Innovation Solution
A system comprising a placement guide with a pilot-tube and a cannula that allows free rotation within the guide, enabling controlled and precise placement of implants at determined depths beneath the skin surface, using a handle portion and placement cannula to govern the implant's depth and orientation, with features like a visualization window for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing implant placement tools are used, then implant insertion can be performed, but restricted motion and excessive force are required causing harm and bruising to tissue
Solution Approach 1:
The cannula is designed to rotate freely within the placement guide rather than being fixed, allowing dynamic adjustment of insertion angle and direction. This rotational freedom enables the practitioner to navigate through different tissue types more easily without applying excessive force, thereby reducing tissue damage and bruising while maintaining ease of operation
Solution Approach 2:
The placement guide includes adjustable parameters such as the angle of the pilot tube and the depth of cannula insertion. By optimizing these parameters, the system allows for controlled insertion that adapts to different tissue characteristics, reducing the force required and minimizing tissue trauma while maintaining operational ease
2Manufacturing precision
If existing implant placement tools are used, then implant insertion can be performed, but precise control over implant depth is lacking
Solution Approach 1:
The placement guide acts as an intermediary device between the practitioner and the tissue, providing a structured pathway through the pilot tube. This intermediary component ensures that the cannula follows a predetermined trajectory and reaches the exact desired depth, achieving precise depth control without requiring complex adjustment mechanisms or multiple components
Solution Approach 2:
The placement guide is prepared in advance with a pre-determined pilot tube angle and depth markings. This preliminary configuration ensures that when the cannula is inserted, it automatically follows the correct path to the target depth, achieving precision without requiring complex real-time adjustments or sophisticated control systems
