Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical guiding apparatuses face instability and inaccuracy due to the inability to accurately represent anatomical surfaces, especially with soft tissues not visible in medical images, leading to poor fit and stability during surgical procedures.
Innovation Solution
The development of adaptive surface surgical guiding apparatuses with a combination of rigid and variable deformable portions, where the deformable portions conform to the shape of anatomical surfaces, providing a secure and stable attachment despite inaccuracies in anatomical modeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a rigid surgical guiding apparatus is designed based on pre-operative medical imaging data, then the apparatus can provide precise surgical instrument guiding positions, but the apparatus becomes unstable when anatomical surfaces vary from the imaged shape
Solution Approach 1:
The surgical guiding apparatus transitions from a completely rigid structure to a dynamic structure incorporating deformable portions that can adapt to anatomical variations. The deformable portion allows the apparatus to dynamically adjust its shape to match the actual anatomical surface, maintaining both precision and stability.
Solution Approach 2:
The apparatus utilizes changes in physical parameters of the deformable portion (flexibility, deformability) to accommodate variations in anatomical surface geometry. By changing the physical state from rigid to deformable in specific regions, the apparatus can adapt to different anatomical configurations while maintaining guiding precision.
2Strength
If the surgical guiding apparatus is made completely rigid to maintain structural integrity, then the apparatus provides stable support, but the apparatus cannot accommodate anatomical surface variations leading to poor fit
Solution Approach 1:
The apparatus applies different structural qualities to different regions: rigid portions in areas requiring structural integrity and support, and deformable portions in areas requiring adaptability to anatomical variations. This local differentiation allows the apparatus to simultaneously achieve both strength and adaptability.
Solution Approach 2:
The surgical guiding apparatus combines rigid and deformable materials or structural configurations within a single device. This composite approach allows different portions of the apparatus to exhibit different mechanical properties, achieving both structural integrity and anatomical adaptability.
3Adaptability or versatility
If adjustable components are added to improve fit on variable anatomy, then the apparatus can adapt to different shapes, but the apparatus complexity increases leading to imprecise guiding positions
Solution Approach 1:
The apparatus incorporates a deformable portion that functions as a flexible element capable of conforming to anatomical surfaces without requiring complex adjustable mechanisms. This flexible shell approach provides adaptability while maintaining relative simplicity in the overall device structure.
