Problem
Conventional implant extracting devices face challenges in easy removal and replacement of worn components, maintaining a movable implant engaging jaw in a commanded position without external forces, and achieving a compact design without compromising functionality.
Innovation Solution
An implant extracting tool with an elongate housing, a movable jaw, and a linkage assembly that includes a telescopic rod assembly and a cam lock mechanism, allowing for detachable inserts and a locking mechanism to secure the jaw in position, facilitating easy replacement and maintaining grip on the implant.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If conventional implant extracting devices are used, then the device structure is simple, but the components cannot be easily removed and replaced when worn
Solution Approach 1:
The extracting device is divided into modular components including a handle, jaw, and interchangeable inserts that can be independently removed and replaced. The jaw is separable from the handle, and inserts can be exchanged without replacing the entire device, enabling easy maintenance while keeping the overall structure manageable.
Solution Approach 2:
The device incorporates a movable jaw that can transition between open and closed positions through a linkage mechanism. This dynamic capability allows the jaw to engage and disengage from the implant, facilitating easy replacement of worn components while maintaining functional complexity only when needed.
2Reliability
If a movable jaw is provided for engaging the implant, then the device can maintain grip on the implant, but the jaw cannot remain in a commanded position without external forces
Solution Approach 1:
A spring mechanism is incorporated to provide preliminary counteracting force that biases the jaw toward a commanded position. This spring-loaded system automatically counteracts gravitational forces and other external influences, maintaining jaw position stability without requiring continuous external force or complex active control systems.
Solution Approach 2:
The spring mechanism enables the jaw to self-correct and maintain its commanded position automatically. The system serves itself by using the spring's stored energy to counteract disturbances, eliminating the need for external intervention or complex control mechanisms to maintain jaw positioning.
3Length of moving object
If the device is made shorter for compactness, then the device size is reduced, but the functionality of the tool is compromised
Solution Approach 1:
The device employs a telescopic rod assembly where segments can extend and retract. The rod contains nested sections that can be extended when additional length is needed for functionality, and retracted when compact size is required, allowing the device to adapt its length based on operational requirements without permanently compromising either compactness or functionality.
Solution Approach 2:
The telescopic rod assembly provides dynamic length adjustment capability. The rod can transition between extended and retracted states, enabling the device to optimize its length for specific tasks while maintaining a compact form factor for storage and handling, thus preserving functionality without sacrificing compactness.

Function Achieved in This Case
The device enables easy replacement of worn parts, maintains the jaw in a commanded position without external forces, and achieves a compact design while ensuring effective implant extraction.
Implementation Method 1
A linkage is secured and received within the elongate recess of the housing. The linkage is pivotally secured to the jaw such that operation of the linkage slides the jaw within the slot towards and away from the opening.
Implementation Method 2
An implant extractor comprising: an elongate housing having: a proximal end configured for connection to an extraction tool, a distal end for operably engaging an implant, and an elongate recess extending therein; a jaw slidably received within the elongate recess and extending to the distal end of the elongate housing
