Solution Overview
Problem
Existing navigation systems in surgical procedures face errors due to obstructed line-of-sight between tracking devices and sensing devices, leading to delays and inaccuracies, particularly in surgeries using navigation equipment like tracking cameras and magnetic field sensors.
Innovation Solution
A system comprising a guidance station with a localizer, controllers, and a display that evaluates surgical procedure information to determine desired placements of robotic systems and objects in the operating room, providing visual representations to guide manual placement and reduce obstructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If navigation systems rely on unobstructed line-of-sight between tracking devices and sensing devices, then positioning accuracy is improved, but setup complexity and time increase due to the need for careful device arrangement
Solution Approach 1:
The system provides real-time feedback through visual displays showing the current placement versus desired placement of robotic systems and tracking devices. The feedback loop allows users to adjust device positions based on displayed guidance information, ensuring unobstructed line-of-sight while simplifying the arrangement process through iterative correction rather than complex pre-planning
Solution Approach 2:
The visual display system acts as an intermediary between the navigation system's requirements and the user's arrangement actions. It translates complex positioning requirements into simple visual guidance, mediating the interaction between tracking devices, sensing devices, and users to achieve accurate positioning without requiring users to directly comprehend complex line-of-sight constraints
2Ease of operation
If traditional written protocols are used to arrange objects in the operating room, then ease of operation is maintained through simple instructions, but productivity decreases due to manual arrangement and lack of real-time guidance
Solution Approach 1:
The system enables self-service arrangement where the operating room environment guides its own setup through automated visual feedback. The display system automatically shows current versus desired placements, allowing users to independently arrange devices correctly without relying on external written protocols or expert intervention, thereby maintaining ease of operation while dramatically improving setup efficiency
Solution Approach 2:
The system performs preliminary computational analysis of the operating room layout and device positions before the user begins arrangement. By pre-calculating optimal placements and providing visual guidance from the start, the system eliminates the need for trial-and-error manual arrangement according to written protocols, improving productivity while keeping the user interface simple
3Measurement precision
If navigation systems discontinue operation when line-of-sight is obstructed, then measurement precision is maintained by avoiding errors, but loss of time occurs due to procedure delays
Solution Approach 1:
The system performs preliminary arrangement guidance to prevent line-of-sight obstructions before they occur during the surgical procedure. By showing the desired placement of tracking devices and robotic systems before the procedure starts, the system ensures optimal positioning that maintains unobstructed line-of-sight throughout surgery, thereby maintaining navigation accuracy without causing procedure delays
Solution Approach 2:
The visual display system serves as an intermediary that prevents the need to discontinue navigation by proactively guiding correct device placement. It mediates between potential line-of-sight obstructions and navigation accuracy by providing real-time visual feedback on device positions, allowing continuous operation while maintaining precision through proper arrangement
