Adjustable Jaw Orthognathic Bending Pliers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in craniofacial surgery is the difficulty in manufacturing orthopedic implants, such as bone plates, that can conform to varying anatomical shapes and sizes, necessitating tools and methods to bend these implants on a case-by-case basis to fit specific patient anatomy effectively.
Innovation Solution
A bending tool with a first and second jaw assembly, where the second jaw assembly is movably coupled to the first, allowing for a variable adjustment distance to bend the orthopedic implant by applying force to offset the implant portions, enabling precise shaping to fit individual anatomical needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If orthopedic implants are manufactured with fixed standard shapes, then manufacturing cost and time are reduced, but the implants cannot conform to varying patient anatomical shapes and sizes
Solution Approach 1:
The patent applies preliminary action by pre-configuring the bending tool with adjustable jaw assemblies that can be set to specific offset distances before use. The adjustment members are pre-positioned relative to the bases to define predetermined offset distances, allowing the implant to be bent to the exact required shape during surgery without complex real-time calculations or adjustments.
Solution Approach 2:
The patent implements parameter changes by providing multiple predetermined offset distances through the adjustable jaw assemblies. Different offset distances can be selected based on the specific patient anatomy and surgical requirements, allowing the same tool to accommodate various anatomical variations by simply changing the adjustment member position rather than manufacturing different tools.
2Manufacturing precision
If custom bending tools are designed for each specific bending requirement, then bending precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by designing a single bending tool that can perform multiple bending operations with different offset distances. The jaw assemblies with adjustable adjustment members allow the same tool to accommodate various bending requirements, eliminating the need for multiple specialized tools while maintaining precision for each specific application.
Solution Approach 2:
The patent implements dynamics by making the jaw assemblies movable and adjustable relative to each other. The adjustment members can be repositioned along the bases to change the offset distance, transforming a static tool into a dynamic one that adapts to different surgical needs while maintaining structural integrity and bending precision.
3Adaptability or versatility
If the adjustment member is made movable relative to the base, then the tool can accommodate varying anatomical needs, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the jaw assembly into separate movable components: the adjustment member and the base. This segmentation allows independent adjustment of the offset distance while maintaining the overall structural integrity of the tool. The segmented design enables flexibility without requiring complete redesign of the entire jaw assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool effectively bends orthopedic implants to achieve a predetermined offset, allowing for precise fitting and alignment during craniofacial surgery, addressing the variability in patient anatomy and enhancing surgical outcomes.
Implementation Method 1
moving the first and second jaw assemblies relative to each other causes at least one of the first and second jaws to move in at least a first lateral direction that decreases the adjustment distance and causes the first and second jaws to apply a force to a portion of the orthopedic implant that is disposed in the gap, thereby bending the orthopedic implant

AI summary
A bending tool can be configured to bend an orthopedic implant and includes a first jaw assembly and a second jaw assembly. The first jaw assembly includes a first base and a first adjustment member that is movably coupled to the first base. The second jaw assembly is movably coupled to the second jaw assembly. The second jaw assembly includes a second base and a second adjustment member that is movably coupled to the second base.
