Modular Jaw Dovetail Lock Orthopedic Extraction Tool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Orthopedic implant extraction tools often experience jaw breakage due to improper or unintended use, necessitating a modular jaw design that can withstand clamping and extraction forces without requiring replacement of the entire tool.
Innovation Solution
A modular jaw with an elongated body, a claw for engaging orthopedic implants, and a locking mechanism featuring a dovetail lock and ball detent for secure attachment to the orthopedic implant extraction tool, allowing for easy replacement and enhanced durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-modular jaw design is used, then the tool structure is simpler, but the entire tool must be replaced when the jaw breaks
Solution Approach 1:
The jaw is designed as a separate, detachable module that can be independently replaced from the tool body. The modular jaw assembly includes the jaw itself and an attachment mechanism that interfaces with the tool, allowing the jaw to be segmented from the main tool structure for easy replacement while maintaining overall tool integrity.
Solution Approach 2:
The jaw is nested within a replaceable assembly that interfaces with the tool body. The modular jaw assembly can be inserted into and locked within the tool's receiving structure, allowing the jaw to be contained within the tool system while maintaining independent replaceability.
2Strength
If the entire tool is replaced when the jaw breaks, then jaw durability is less critical, but tool cost and downtime increase
Solution Approach 1:
By segmenting the jaw from the tool body into separate replaceable components, the system allows only the worn or damaged jaw to be replaced rather than the entire tool, significantly reducing replacement time and maintaining high jaw durability requirements.
Solution Approach 2:
The modular jaw design enables the jaw to be discarded when worn and recovered/replaced independently from the expensive tool body, minimizing loss of time and resources by preserving the reusable portions of the tool while replacing only the consumable jaw component.
3Ease of repair
If a modular jaw design is implemented, then jaw replacement is easier, but the locking mechanism complexity increases
Solution Approach 1:
The locking mechanism is segmented into discrete components (locking features on the jaw, corresponding receptacles on the tool body, and retention elements) that work together to provide secure attachment while allowing simple assembly and disassembly procedures.
Solution Approach 2:
The modular jaw assembly is designed as a relatively simple, potentially disposable or frequently replaceable component with a straightforward locking mechanism that prioritizes ease of replacement over complex security features, appropriate for a consumable tool component.

AI summary
A modular jaw for attachment to an orthopedic implant extraction tool that includes an elongated body, a claw about a distal end of the elongated body for engaging an object, and a locking mechanism about a posterior end of the elongated body for engaging the orthopedic implant extraction tool. The locking mechanism includes a dovetail lock, a detent mounted to the dovetail lock, and a distally facing surface about a proximal end of the elongated body.
