Articulating Implant Holder Profile Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical procedures for implant insertion often require significant tissue dissection and retraction, leading to trauma and potential scarring, and there is a need for methods and instruments that minimize these effects while facilitating implant placement, especially in minimally invasive procedures.
Innovation Solution
The development of an articulating implant holder system integrated with an insertion instrument that allows the implant to transition from a reduced profile for minimally invasive insertion to an increased profile for secure positioning within the surgical site, enabling minimization of tissue disruption and facilitating precise orientation and engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional surgical instruments with fixed profile are used for implant insertion, then the implant can be securely held, but significant tissue dissection and retraction are required causing trauma and scarring
Solution Approach 1:
The implant holder is designed with dynamic profile transformation capability, allowing it to change from a reduced profile configuration during insertion to an increased profile configuration after insertion. This dynamic adaptation enables the holder to pass through narrow surgical pathways with minimal tissue disruption, then expand to securely engage the implant at the surgical site, thereby reducing tissue trauma while maintaining ease of operation
Solution Approach 2:
The system utilizes parameter changes in the physical dimensions of the implant holder, specifically transforming the profile size from reduced to increased. This parameter transformation allows the holder to navigate through constrained surgical access points with minimal tissue dissection, then transition to a larger profile that provides adequate engagement surface area for secure implant placement, resolving the contradiction between minimizing tissue trauma and ensuring proper implant insertion
2Object-affected harmful factors
If minimally invasive access is used to reduce tissue dissection, then tissue trauma is minimized, but the implant cannot be properly positioned or engaged at the surgical site
Solution Approach 1:
The dynamic profile transformation of the implant holder enables precise implant positioning through minimally invasive access. The holder maintains a reduced profile during insertion to minimize tissue trauma, then transforms to an increased profile at the surgical site that provides the necessary structural capability for precise engagement and positioning of the implant, thereby achieving both minimal tissue trauma and precise implant placement
Solution Approach 2:
The implant holder utilizes dimensional transformation by changing its profile orientation from reduced to increased after insertion. This dimensional change allows the system to pass through narrow minimally invasive access pathways, then expand in the surgical space to provide adequate surface area and geometric configuration for precise implant engagement and positioning, resolving the contradiction between minimal access and positioning precision
3Object-affected harmful factors
If the implant holder maintains a reduced profile throughout insertion and positioning, then tissue trauma is minimized, but the implant cannot be securely engaged at the surgical site
Solution Approach 1:
The implant holder dynamically transforms its profile from reduced to increased after insertion, enabling it to minimize tissue trauma during passage through surgical pathways, then provide sufficient engagement strength at the surgical site. This dynamic adaptation ensures that the holder has adequate surface area and structural configuration to securely engage the implant only when needed, after minimizing tissue disruption during insertion
Solution Approach 2:
The implant holder's profile transformation can be segmented into distinct phases: insertion phase with reduced profile to minimize tissue trauma, and engagement phase with increased profile to provide secure implant fixation. This segmentation allows the system to optimize for different functional requirements at different stages of the surgical procedure, achieving both minimal tissue trauma and strong implant engagement
