Interphalangeal Implant Retainer for Contact-Free Precise Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interphalangeal implants require complex surgical procedures that involve direct handling and potential contamination of medical personnel, and involve multiple parts, complicating the implantation process and prolonging patient mobilization.
Innovation Solution
An implant retainer and implantation tool with a limb support, driving rod, and actuation mechanism that allows for precise, contact-free handling and insertion of interphalangeal implants, reducing the number of parts and simplifying the implantation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional implantation tool is used for interphalangeal implants, then the tool can be stored in a small space, but the tool cannot accommodate large implants and requires multiple tools for different implant sizes
Solution Approach 1:
The implantation tool is divided into a handle portion and a separate driver portion that can be detached and stored within the handle. This segmentation allows the tool to accommodate different implant sizes by selecting appropriate drivers while maintaining compact storage when drivers are nested in the handle.
Solution Approach 2:
The driver portion is designed to be nestable within the handle portion when not in use. This nesting capability allows the tool to maintain a compact storage profile while being able to accommodate various implant sizes by attaching different drivers as needed.
2Adaptability or versatility
If the implantation tool has a fixed structure, then the tool is simple to manufacture, but the tool cannot be adjusted for different implant positions and orientations
Solution Approach 1:
The driver portion incorporates rotational and articulation capabilities that allow it to be dynamically adjusted to different positions and orientations. This dynamic structure enables precise placement of implants at various angles and locations while maintaining a relatively simple overall tool design through modular components.
3Ease of manufacture
If the driver is directly connected to the handle, then the tool structure is simple, but the driver cannot be easily replaced for different implant sizes
Solution Approach 1:
The tool is segmented into a handle portion and a separate driver portion with distinct functions. The driver portion can be detached from the handle and replaced with different drivers suited for various implant sizes, combining structural simplicity with operational flexibility.
Solution Approach 2:
The driver portion is designed as a replaceable component that can be discarded after use and recovered for storage within the handle or replaced with another driver. This approach simplifies the overall structure while enabling easy replacement for different implant requirements.

AI summary
An interphalangeal implant retainer (20) for retaining an interphalangeal implant (10) is to be used with an implantation tool (30), the implantation tool (30) comprising: a limb support (31) for supporting a phalangeal limb, a driving rod (35), and an actuation mechanism (50) for actuating the driving rod, wherein the driving rod is movable for moving the interphalangeal implant towards the limb support. The implant retainer comprises a jig part (21), which has a plate-shape and includes an implant aperture (22) for retaining an interphalangeal implant.
