Rotatable Engagement Member for Implant Insertion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current insertion instruments for correcting bone deformities, such as hammertoes, are difficult to use and lack stability, making it challenging for surgeons to effectively insert implants during surgical procedures.
Innovation Solution
The development of an implant insertion and removal system that includes an insertion instrument with a handle and a coupling member, along with an engagement member, which provides stability and ease of use for inserting and removing implants in bone deformities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current insertion instruments are used for implant insertion, then the surgical procedure can be performed, but the instrument lacks stability and is difficult to use
Solution Approach 1:
The insertion instrument incorporates a rotatable engagement member that can transition between engaged and disengaged states, allowing dynamic adjustment during the surgical procedure. This enables the surgeon to easily insert and remove implants while maintaining stability during the insertion process, directly resolving the contradiction between ease of operation and reliability.
2Ease of operation
If current insertion instruments are used for implant insertion, then the surgical procedure can be performed, but the instrument is difficult to use
Solution Approach 1:
The insertion instrument is divided into distinct functional components: a handle portion for surgeon control, a coupling member for implant engagement, and a rotatable engagement member for securing/releasing the implant. This segmentation allows each component to perform its specific function efficiently, making the overall instrument easier to use despite the added functionality for stability.
3Reliability
If a rotatable engagement member is added to provide stability, then reliability improves, but device complexity increases
Solution Approach 1:
The rotatable engagement member is integrated into the coupling member structure, combining the functions of implant engagement and securement in a single component. This merging approach provides the necessary stability through the rotatable locking mechanism while minimizing the increase in overall device complexity by avoiding separate dedicated components.
