Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current orthopedic surgery planning systems lack stereoscopic vision, are limited to 2D models, and fail to effectively integrate CT and MRI data, leading to inadequate preoperative planning and increased surgical risks due to inappropriate prosthetic material selection.
Innovation Solution
A 3D orthopedic surgery planning system that imports medical images from various sources, generates 3D anatomical models, allows real-time interaction and manipulation of both 2D and 3D models, and integrates prosthetic material databases for precise planning and selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 2D models are used for surgery planning, then the system is simple and easy to operate, but stereoscopic vision is lost and understanding of different steering axes becomes difficult
Solution Approach 1:
The patent transitions from 2D planar representations to 3D volumetric models, enabling surgeons to visualize anatomical structures and prosthetic implants in three dimensions. This dimensional enhancement restores stereoscopic vision and allows intuitive understanding of spatial relationships and different steering axes while maintaining ease of operation through interactive software control.
Solution Approach 2:
The system creates digital 3D copies of anatomical structures from medical images and virtual copies of prosthetic implants. These digital replicas can be manipulated, positioned, and evaluated in a virtual environment before actual surgery, providing complete spatial information without requiring physical models.
2Productivity
If automatic positioning of prosthesis is implemented, then planning efficiency is improved, but problems with patient positioning during imaging cannot be corrected
Solution Approach 1:
The system provides dynamic, interactive positioning capabilities where surgeons can manually adjust prosthesis location and orientation after automatic positioning is performed. This combination allows efficient automatic initial placement while enabling corrective manual adjustments if patient positioning issues are detected during review of the 3D models.
Solution Approach 2:
The 3D visualization system provides feedback on prosthesis positioning relative to anatomical landmarks and steering axes. Surgeons can review the automatic positioning results, detect any errors related to patient positioning during imaging, and make corrective adjustments with immediate visual feedback on the impact of changes.
3Adaptability or versatility
If CT scan with specific coordinate system is required, then robotic system integration is achieved, but system complexity and patient requirements increase
Solution Approach 1:
The system is designed to import and process standard medical images from multiple modalities (CT, MRI, X-ray) using conventional coordinate systems. The software performs coordinate transformation and registration internally, enabling robotic system integration and surgical guidance without requiring specialized CT scans with custom coordinate systems, thereby reducing patient requirements and overall system complexity.

AI summary
The present application presents a solution that intends to solve the problem of providing an orthopedic surgery planning system with a stereoscopic vision of the patient's lesion. Disclosed is an orthopedic surgery planning system, where a conjunction window of a 2D and 3D environments, comprises an image's axial plan (301), an image's coronal plan (302), an image' sagittal plan (303), a 3D model of an anatomical structure (304), a library templates (305), isosurfaces (306), measurements of distances and angles (307), orientation cube (308), and multi plans 2D in the 3D environments (309). The applicability of this technology expands to the various areas such as orthopedics, orthodontics, implantology and veterinary. In the referred areas exists a surgery planning involving the reconstruction of bone structures, which is accompanied by the preparation of the material to implant in the patient.
