Operating Room Instrument Feedback Using Spatial Navigation Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical navigation systems often provide suboptimal feedback for multiple medical instruments, especially when they are far apart or handled by different surgeons, requiring user interaction and limiting simultaneous navigation and visualization.
Innovation Solution
A method and system that utilize spatial regions defined by virtual planes relative to anatomical elements, associating each medical instrument with a specific region, and providing tailored feedback through navigation views, haptic, and auditory cues to support simultaneous navigation of multiple instruments by different surgeons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single navigation view is used to visualize multiple medical instruments, then all instruments can be displayed in one view, but the navigation quality deteriorates when instruments are far apart or handled by different surgeons
Solution Approach 1:
The patent divides the operating room space into multiple spatial zones using virtual planes, with each zone dedicated to a specific medical instrument. This segmentation allows each instrument to have its own optimized navigation view while maintaining overall situational awareness, resolving the contradiction between displaying all instruments and providing quality navigation for each.
2Adaptability or versatility
If user interaction is required to select which instrument to visualize, then navigation feedback can be tailored to the selected instrument, but the system complexity and time required increase
Solution Approach 1:
The system automatically assigns instruments to spatial zones and generates appropriate navigation views without requiring user selection or interaction. The navigation system serves itself by autonomously determining which instrument to visualize based on the spatial zone configuration, eliminating the need for manual instrument selection while maintaining customized feedback for each instrument.
3Loss of information
If a single navigation view displays multiple instruments, then all instrument poses are visible, but the precision and detail for each individual instrument decrease
Solution Approach 1:
By segmenting the operating room into multiple spatial zones, each instrument is assigned to its own dedicated zone with an optimized navigation view. This allows high-precision visualization of each instrument's pose and orientation without the clutter and information loss that would occur in a single shared view, while still maintaining awareness of all instruments through the zone-based organization.

AI summary
A method for supporting users in an operating room is provided. The method is performed by a processing system and comprises obtaining spatial information indicative of a plurality of spatial regions in the operating room, each of the plurality of spatial regions being associated with one or more feedback parameters, and obtaining tracking information indicative of tracked poses of a plurality of medical instruments in the operating room. The method further comprises associating, based on the spatial information and the tracking information, each of the medical instruments to at least one of the spatial regions, and triggering feedback, for each of the medical instruments, according to the one or more feedback parameters of the associated at least one spatial region. A system, a computer program and a carrier are also provided.
