Preoperative Surgical Simulation With Patient-Specific Tool Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons face challenges in performing unfamiliar or infrequently performed surgical procedures due to difficulties in visualizing and executing the procedures accurately, even with the assistance of surgical navigation systems.
Innovation Solution
A surgical system that includes a navigation system and a robotic manipulator, allowing for preoperative simulation of surgical procedures using either physical or virtual tools, which generates planning parameters for intraoperative execution, and can optionally perform the procedure autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surgeons rely on surgical navigation systems for unfamiliar procedures, then surgical guidance is provided, but surgical accuracy and confidence remain insufficient
Solution Approach 1:
The system performs preoperative simulation of surgical procedures before actual surgery. The surgical plan is rehearsed virtually using patient-specific anatomical data, allowing surgeons to practice and refine their approach beforehand. This preliminary action builds surgeon confidence and improves accuracy when performing unfamiliar or complex procedures.
Solution Approach 2:
The system creates a virtual copy of the patient's anatomy using imaging data (CT, MRI) to generate three-dimensional models. These digital twins allow surgeons to practice procedures on accurate replicas without risk to the actual patient, improving both confidence and precision for unfamiliar surgical scenarios.
2Ease of operation
If preoperative simulation is performed using physical models, then surgical procedure visualization is improved, but time and resource consumption increase
Solution Approach 1:
The system replaces physical physical models with virtual three-dimensional models displayed on computer screens. The virtual simulation environment provides the same surgical visualization benefits without the time-consuming processes of creating physical models from casting or molding patient anatomy.
Solution Approach 2:
The virtual simulation system serves multiple functions: it visualizes the surgical procedure, plans the approach, rehearses the workflow, and generates detailed surgical guides. This multi-functionality consolidates what would otherwise require separate physical models and planning sessions into a single integrated digital platform.

AI summary
System and methods for simulating a surgical procedure are provided. The system includes a non-transitory computer-readable medium including instructions, which when executed by one or more processors, are configured to execute a surgical planning program. The surgical planning program is configured to track a tool relative to a model of an anatomy during a preoperative surgical simulation, generate a planning parameter based on the tracking of the tool relative to the model of the anatomy during the preoperative surgical simulation, and store the generated planning parameter. The system may also include a surgical system configured to load the generated planning parameter from the surgical planning program.
