Surgical Image Display Control by Instrument and Vertebra Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing preoperative medical images, such as CT scans, are not easily integrated into surgical procedures, requiring manual designation of instruments and vertebrae, leading to errors and disruption of the surgical workflow.
Innovation Solution
A system that dynamically manages and integrates preoperative and intraoperative image data using a camera array and processing device to automatically track surgical instruments and vertebrae, allowing real-time registration and display of relevant images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual designation of instruments and vertebrae is used to view preoperative images, then the surgeon can access relevant image data, but errors in identification occur and surgical workflow is disrupted
Solution Approach 1:
The system automatically tracks surgical instruments and identifies vertebrae using computer vision and image processing, eliminating the need for manual designation. The mediated reality system self-updates to display relevant preoperative images based on detected instrument positions, ensuring both continuous information access and high identification accuracy without surgeon intervention
Solution Approach 2:
The patent replaces manual mechanical designation with automated optical tracking and image processing systems. Cameras capture surgical scene images, and processing devices automatically identify instruments and vertebrae, substituting human manual operations with automated computational systems to improve reliability while maintaining information access
2Ease of operation
If manual adjustments are made continuously to view preoperative images, then the surgeon can maintain focus on the operation, but the procedure time is prolonged
Solution Approach 1:
The system maintains continuous automatic tracking of surgical instruments and continuous display of relevant preoperative images throughout the procedure. This eliminates intermittent manual adjustments, allowing the surgeon to maintain focus without interruption while the system continuously provides necessary visual information, thereby reducing procedure time
Solution Approach 2:
Preoperative images are pre-processed and registered with the surgical scene before the procedure begins. The system pre-establishes the relationship between instruments, vertebrae, and images, so that during surgery, only automatic tracking is needed without real-time manual configuration, enabling continuous operation without time loss

AI summary
Systems, methods, and devices for selecting and managing imaging systems, such as surgical imaging systems, are disclosed herein. A representative method can include detecting the introduction of a first instrument into a bounding region around a vertebra and designating the first instrument as an active instrument. The active instrument can be used to control the display of imaging data on a user interface. The method can further include detecting that the first instrument has left the bounding region while a second instrument has entered the bounding region, and designating the second instrument as the active instrument. Another representative method can include defining multiple bounding regions around corresponding vertebra, detecting the entry of the active instrument into one of the bounding regions, and designating the vertebra associated with the bounding region as an active vertebra for further control of the display of imaging data on the user interface.
