Solution Overview

Problem

Existing automated planning systems for orthopedic surgeries lack accuracy and surgeon confidence due to reliance on deterministic rules rather than patient-specific data, leading to potential improper range of motion and increased probability of prosthesis failure.

Innovation Solution

A computing system uses a machine learning model to generate a predicted prosthesis shape based on medical image data, allowing for the identification and recommendation of an appropriate orthopedic prosthesis and its optimal positioning in 3D space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If deterministic rules are used for prosthesis selection, then the planning process is simple and fast, but the accuracy and surgeon confidence are insufficient

Engineering Contradiction:
Improveaccuracy of prosthesis recommendationVSAvoidcomplexity of planning system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces deterministic rule-based mechanical decision-making with a machine learning model that processes medical image data. The ML model analyzes patient-specific anatomical features and predicts optimal prosthesis selections, substituting rigid algorithmic rules with adaptive data-driven predictions that improve accuracy while managing complexity through automated processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system transforms the approach from fixed rule parameters to dynamic parameters derived from medical image data. By extracting anatomical measurements and features from patient scans and feeding them into the ML model, the system adapts its recommendations based on actual patient geometry rather than predetermined rules, improving precision without proportionally increasing complexity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If patient-specific image data is used with machine learning, then the accuracy of recommendations increases, but the computational complexity and processing time increase

Engineering Contradiction:
Improvereliability of prosthesis selectionVSAvoidprocessing time for analysis
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary processing of medical image data to extract relevant anatomical features and parameters before the actual prosthesis selection. By pre-processing and pre-extracting key measurements from patient scans, the ML model receives refined input that reduces computation time during the critical decision-making phase, maintaining high reliability while minimizing time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the essential anatomical features and parameters from comprehensive medical image data that are most relevant to prosthesis selection. Rather than analyzing entire datasets, the system identifies and processes only the critical measurements needed for accurate predictions, reducing computational burden and processing time while maintaining high reliability through targeted feature extraction.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A method for automatically recommending an orthopedic prosthesis for implantation in a patient comprises obtaining, by a computing system, medical image data for the patient; applying, by the computing system, a machine learning model to generate a predicted prosthesis shape for the patient based on the medical image data for the patient; identifying, by the computing system, from a plurality of orthopedic prostheses available for implantation in the patient, an orthopedic prosthesis that corresponds to the predicted prosthesis shape; and recommending, by the computing system, the identified orthopedic prosthesis for implantation in the patient.
