Patient-Specific Bone Buttress Fitting for Fracture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic technologies face challenges in accurately reconstructing and customizing implants for patients with fractured or deformed bones, particularly in achieving a precise fit and alignment.
Innovation Solution
The method involves creating a patient-specific 3D model of the fractured bone, applying a buttress to the model to verify fit, and using computer-aided design instructions to generate a tangible model for surgical guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If patient-specific 3D modeling and customization processes are used to achieve precise fit and alignment of bone implants, then manufacturing precision and surgical accuracy are improved, but device complexity and manufacturing time are increased
Solution Approach 1:
The patent applies preliminary action by creating patient-specific 3D models and virtual trial assemblies before actual surgery. The system performs pre-operative planning, generates customized implant designs, and creates patient-specific cutting guides in advance, allowing surgeons to verify fit and alignment virtually before the surgical procedure, thereby achieving precise fit without increasing operational complexity during surgery
Solution Approach 2:
The patent uses copying by creating accurate virtual 3D replicas of the patient's actual bone anatomy from CT scan data. These virtual models serve as digital copies that can be manipulated, measured, and used for implant design without requiring physical models, reducing manufacturing complexity while maintaining high precision
2Measurement precision
If virtual 3D modeling and computer-aided design are used to plan bone surgery, then surgical accuracy and alignment precision are improved, but measurement and detection difficulty are increased
Solution Approach 1:
The patent replaces mechanical measurement systems with computer-aided imaging and virtual modeling. Instead of relying on physical measurement tools and manual anatomical detection during surgery, the system uses CT scan data processing, 3D reconstruction algorithms, and virtual trial assembly software to achieve precise measurements and alignment planning pre-operatively
Solution Approach 2:
The patent introduces an intermediary computational layer between raw imaging data and surgical decision-making. The system processes CT scans into 3D models, performs virtual implant trials, and generates surgical guides as intermediary steps that translate complex anatomical data into actionable surgical plans, simplifying the detection and measurement process
