Finger Bone Implant Design Using 3D Measurement Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for designing finger bone implants struggle to accommodate the varied shapes of individual finger bones, leading to difficulties in achieving a precise fit during surgeries.
Innovation Solution
A method involving 3D image collection, measurement, and derivation of average values for finger bone lengths, cross-sectional widths, and thicknesses to standardize implant shapes, which are then stored in a database for manufacturing patient-specific implants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single standardized implant shape is used for all patients, then the manufacturing process is simple and cost-effective, but the implant cannot accommodate the varied shapes of individual finger bones
Solution Approach 1:
The patent applies parameter changes by systematically varying the geometric parameters (length, width, thickness, curvature) of implant designs based on statistical analysis of patient finger bone measurements. Multiple implant variants are created by adjusting these parameters to match different patient anatomies, resolving the contradiction between standardized manufacturing and individualized fit.
Solution Approach 2:
The patent implements local quality by customizing specific regions of the implant to match corresponding regions of the patient's finger bone. Different sections of the implant can have different geometric characteristics optimized for local anatomical requirements, allowing both standardized manufacturing processes and individualized adaptation.
2Manufacturing precision
If custom implants are designed for each patient based on individual measurements, then the implant fit is optimized, but the design and manufacturing process becomes complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing multiple implant design variants in a database before actual surgery. During surgery, the appropriate pre-designed implant can be quickly selected and manufactured based on the patient's specific measurements, avoiding complex real-time design while maintaining high precision fit.
Solution Approach 2:
The patent implements universality by creating a family of implant designs that can serve multiple patient types. A standardized set of pre-designed implants covers a range of anatomical variations, allowing the system to handle diverse patient needs through a unified design framework rather than completely custom designs for each case.
3Measurement precision
If comprehensive 3D measurements and statistical analysis are performed to derive average values, then the implant design is optimized for patient population, but the data collection and processing time increases
Solution Approach 1:
The patent applies preliminary action by performing comprehensive 3D measurements and statistical analysis during the pre-clinical research phase to establish reference data and average values. This upfront investment in data collection creates a reusable database that can be applied to multiple patients without repeating the time-consuming measurement and analysis process for each individual case.
