Virtual Guide for Surgical Landmark Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical procedures lack effective guidance for accurately positioning anatomical elements and implants, especially in cases where patient anatomy changes over time due to medical implants or surgical steps.
Innovation Solution
A system utilizing a display to present an augmented image with virtual guides, tracked and generated based on parameters of surgical landmarks, such as angles, positions, and orientations, to assist surgeons in minimizing forces and pressures applied during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional surgical guidance methods are used, then the surgical procedure can be performed, but the accuracy of positioning anatomical elements and implants deteriorates
Solution Approach 1:
The patent creates a virtual copy of the patient's anatomy through 3D modeling from preoperative images. This virtual model serves as a dynamic guide that replicates the patient's unique anatomical structure, allowing precise positioning guidance without physical templates or markers on the actual patient.
Solution Approach 2:
The system transitions from 2D preoperative images to 3D volumetric models, enabling multi-angle viewing and spatial reasoning. The virtual guide system operates in three-dimensional space, allowing the surgeon to perceive anatomical relationships and implant positioning requirements from multiple perspectives simultaneously.
2Productivity
If patient anatomy changes due to implants or surgical steps, then the surgical procedure progresses, but the accuracy of subsequent positioning deteriorates
Solution Approach 1:
The virtual guide system is dynamically updated throughout the surgical procedure. As the surgeon performs each step and anatomy changes, the system detects these changes through tracking markers or sensor feedback and automatically updates the 3D model and virtual guides to reflect the current anatomical state, maintaining positioning accuracy.
Solution Approach 2:
The system incorporates real-time feedback mechanisms where the actual position of anatomical landmarks and implants is continuously monitored and compared against the virtual guide. This feedback loop allows the system to detect deviations and alert the surgeon, enabling corrective actions to maintain precision.
3Force
If virtual guides are generated based on preoperative images, then the surgical guide is available before the procedure, but the guides cannot adapt to real-time anatomical changes
Solution Approach 1:
The system performs preliminary actions by generating the complete virtual guide system from preoperative images before the surgical procedure begins. This includes creating 3D models, planning implant positions, and pre-calculating guidance paths, so that all guidance infrastructure is ready for immediate use during surgery.
Solution Approach 2:
The virtual guide system transitions from a static preoperative plan to a dynamic real-time guidance system. The same 3D model framework used preoperatively is continuously updated during surgery to accommodate anatomical changes, maintaining adaptability throughout the procedure.

AI summary
Systems, methods and devices for performing a surgical procedure using a virtual guide are provided. The system may include a display configured to display an augmented image in an environment. A surgical landmark may be tracked and a parameter of the surgical landmark may be determined. A virtual guide for presentation within the augmented image may be generated and the display may present the virtual guide within the augmented image.
