Robotic Surgical Data Playback for Real-Time Deviation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical planning systems for arthroplasty procedures, such as PKA, TKA, and THA, often require modifications during surgery based on intraoperative patient information, lacking effective tools for real-time guidance and deviation feedback.
Innovation Solution
A computer-assisted surgical system that collects robotic surgical data to generate a graphical depiction of the procedure, providing real-time graphical user interfaces with deviation feedback, allowing selective viewing and playback of surgical data, including three-dimensional models and augmented reality overlays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If surgical plans are developed before surgery based on preoperative information, then surgical planning can be completed in advance, but the system lacks real-time guidance and cannot adapt to intraoperative findings
Solution Approach 1:
The system performs preliminary surgical planning before surgery based on preoperative imaging and patient-specific anatomy. The surgical plan including cutting planes, drill hole locations, and implant positioning is prepared in advance, allowing the surgical team to be fully informed before entering the operating room while still enabling real-time modifications during the procedure
Solution Approach 2:
The system provides real-time visual feedback during surgery by overlaying the preoperative surgical plan onto live intraoperative images. This allows surgeons to see deviations from the planned procedure immediately and make adjustments based on actual intraoperative findings, bridging the gap between preoperative planning and intraoperative adaptability
2Adaptability or versatility
If surgeons modify the surgical plan during surgery based on intraoperative information, then adaptability to patient-specific conditions is improved, but real-time guidance and deviation feedback are lacking
Solution Approach 1:
The system automatically compares the modified surgical plan against the original preoperative plan and provides real-time visual feedback showing the deviations. This allows surgeons to understand the implications of their modifications immediately and make informed decisions about further plan changes based on actual intraoperative conditions
Solution Approach 2:
The system acts as an intermediary between the surgeon's manual plan modifications and the surgical execution. It processes the modified plan, generates updated visual guidance, and presents it to the surgeon in real-time, ensuring that all team members are aware of the current surgical plan and any deviations from the original plan
3Reliability
If comprehensive surgical data is collected from robotic components, then surgical training and analysis can be enhanced, but data management and processing complexity increases
Solution Approach 1:
The system uses a single integrated robotic surgical system that performs multiple functions: it executes the surgical procedure, collects comprehensive surgical data, provides real-time visual guidance, and enables surgical training. This multi-functional approach reduces the need for separate data collection devices and simplifies the overall system architecture while maintaining comprehensive data capture capabilities
Data Source
AI summary
A method for utilizing robotic surgical data for providing surgical training is disclosed. The method includes collecting, by a computing device, data related to a surgical procedure from one or more components of a computer-assisted surgical system. At least one of the one or more components is a robotically controlled surgical device. A graphical depiction representative of the surgical procedure is generated based on the collected data from the one or more components of the computer-assisted surgical system and one or more images providing a visual depiction of a patient's anatomy. A graphical user interface is output to a display device. The graphical user interface includes the graphical depiction of the surgical procedure and the collected data from the one or more components of the computer-assisted surgical system, to provide surgical training.
