Teleoperated Surgery Control System with Automatic Anti-Stagnation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Clinicians experience fatigue and discomfort during prolonged teleoperated surgical procedures due to maintaining a constant position, which can be exacerbated by performing multiple procedures in a single day, leading to increased patient anesthesia time and potential health issues.
Innovation Solution
A teleoperated surgery user control system with a controller that automatically articulates user control components, such as seating and arm rests, in micro-increments to alleviate fatigue and discomfort, allowing for periodic or continuous adjustments during surgical procedures without interrupting the surgeon's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the clinician maintains a constant position at the user control system to operate instruments during a surgical procedure, then operational precision and control are maintained, but physical fatigue and discomfort increase
Solution Approach 1:
The system dynamically adjusts the position of user control components (such as seating and arm rests) during the surgical procedure. The controller automatically articulates these components in micro-increments to change the clinician's posture and reduce fatigue while maintaining operational precision through continuous control system engagement.
2Object-affected harmful factors
If the clinician takes rest breaks to alleviate fatigue and move away from the user control system, then physical discomfort is reduced, but the length of the surgical procedure increases
Solution Approach 1:
The system performs preliminary actions by proactively adjusting user control components before the clinician experiences significant fatigue. The controller automatically articulates seating and arm rests in micro-increments during the procedure, preventing fatigue accumulation without requiring rest breaks, thereby maintaining procedure efficiency.
3Device complexity
If the user control components remain stationary throughout the procedure, then system simplicity is maintained, but clinician fatigue and stagnation worsen
Solution Approach 1:
The system transitions from a static configuration to a dynamic one by incorporating actuators and controllers that automatically adjust user control components. The controller executes instructions to articulate seating and arm rests in micro-increments, reducing clinician stagnation while maintaining reasonable system complexity through automated control.
4Object-affected harmful factors
If the controller articulates user control components in large increments, then fatigue relief is more pronounced, but the clinician perceives motion and procedural efficiency decreases
Solution Approach 1:
The system applies partial action by articulating user control components in micro-increments rather than full adjustments. The controller makes small, subtle changes to seating and arm rest positions that accumulate to provide fatigue relief while remaining imperceptible to the clinician, thereby maintaining procedural efficiency.

AI summary
An example teleoperated surgery user control system includes a first user control and a controller. The first user control is configured to be used by a user to teleoperate one or more aspects of a surgical system. The first user control includes one or more portions configured to articulate and to support one or more body portions of a user. The controller is communicatively connected to the first user control. The controller is configured to execute instructions to automatically articulate the one or more portions periodically or continually during a surgical procedure teleoperated by the user with the surgical system.
