Adjustable Forceps for Stepped Osteosynthesis Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current forceps designs are not adaptable for use with stepped osteosynthesis clips having an offset crown, limiting their application in osteotomy procedures for conditions like heel valgus or varus.
Innovation Solution
A surgical instrument with a jaw assembly and adjustable arms that can accommodate clips with offset crowns, allowing for precise manipulation and insertion of osteosynthesis clips with varying base and flange thicknesses and offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current forceps designs are used, then they are simple and easy to manufacture, but they cannot accommodate clips with offset crowns
Solution Approach 1:
The forceps incorporates an adjustable jaw assembly that can dynamically change its configuration to accommodate different clip types. The jaw assembly includes movable components that allow adjustment of the jaw spacing and orientation, enabling the forceps to adapt to clips with offset crowns while maintaining a relatively simple base structure.
Solution Approach 2:
The forceps design integrates multiple functions into a single device by making the jaw assembly adjustable. This allows the same forceps to handle both standard clips and offset crown clips, eliminating the need for multiple specialized tools and improving versatility without proportionally increasing complexity.
2Adaptability or versatility
If fixed jaw assembly is used, then the forceps structure is simple, but it cannot accommodate varying base and flange thicknesses
Solution Approach 1:
The jaw assembly includes adjustable components that allow dynamic reconfiguration of the jaw spacing and positioning. This enables the forceps to accommodate varying base and flange thicknesses of different clip types while keeping the adjustment mechanism relatively simple through the use of movable jaw elements rather than complex reconfigurable structures.

AI summary
A system and method for the manipulation and insertion of an osteosynthesis clip (100, 200, 300) is provided. The system includes an osteosynthesis clip and an instrument (10). The osteosynthesis clip includes a base (103, 104) having first and second portions, a thickness, and first and second flanges (107, 108) that extend from the base in which the flanges also have a thickness. The instrument of the system includes a distal end (14) and at least a jaw (80), extending from the distal end. The jaw is dimensioned to receive one of the thicknesses of the base and at least one of the flanges. The jaw is movable to a plurality of jaw positions relative to the distal end.
