Instrument Navigator Rendering for Surgical Configuration Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teleoperated medical systems provide insufficient information for understanding the configuration of surgical instruments, limiting the surgeon's ability to effectively perform minimally invasive procedures.
Innovation Solution
A system and method that includes a teleoperational assembly with a processing unit configured to display synthetic renderings of surgical instruments, allowing for perspective changes and inversions to provide comprehensive instrument visualization.

1Object-affected harmful factors
If real-time imaging is provided during minimally invasive procedures, then the surgical procedure can be performed with reduced tissue damage, but the surgeon may lack sufficient information to understand instrument configuration
Solution Approach 1:
A synthetic rendering system acts as an intermediary between the physical instruments and the surgeon's visual perception. The system captures instrument position and orientation data, processes it through a rendering engine, and presents a virtual representation that complements the real-time imaging, thereby providing complete instrument configuration information without increasing tissue damage
Solution Approach 2:
The system creates a virtual copy or representation of the physical instruments' configuration. By rendering the instruments' positions, orientations, and relationships in a synthetic visual format, the system provides comprehensive configuration information that mirrors the physical state without requiring additional physical intervention or tissue exposure
2Loss of information
If multiple synthetic renderings with different perspectives are displayed, then the surgeon can comprehensively visualize instrument configurations, but the system complexity increases
Solution Approach 1:
The rendering system dynamically adapts the perspective and view based on the surgical context and instrument configuration. Rather than presenting all possible views simultaneously, the system selectively generates and switches between relevant perspectives (e.g., proximal, distal, lateral views) to provide comprehensive instrument configuration information while managing computational resources and interface complexity
Solution Approach 2:
The synthetic rendering display is segmented into multiple view modes or panels, each presenting instrument configuration from a specific perspective or with specific emphasis. This segmentation allows the surgeon to access different levels of detail and spatial relationships without overwhelming the interface with all information at once, thereby managing system complexity while maintaining information completeness

AI summary
A system comprises a teleoperational assembly including a teleoperational manipulator coupled to a plurality of instruments in a surgical environment. The system also comprises a processing unit including one or more processors. The processing unit is configured to display a first synthetic rendering of the plurality of instruments, recognize a triggering event, and change from displaying the first synthetic rendering to displaying a second synthetic rendering of the plurality of instruments in response to recognition of the triggering event.
