Area of Science:

Medical Robotics
Surgical Navigation
Human-Computer Interaction

Background:

The Leap Motion controller offers a low-cost, optical hand tracking solution.
Previous studies explored its precision for surgical robot interfaces, but general conclusions are difficult due to surgical diversity.
Evaluating novel interfaces in specific surgical contexts is crucial.

Purpose of the Study:

To assess the efficacy of the Leap Motion controller for controlling a continuum robot in endonasal pituitary surgery.
To compare user performance with the Leap Motion controller against established systems like the Phantom Omni.

Main Methods:

A phantom study was conducted using the Leap Motion controller to manipulate a concentric tube continuum robot.
User performance metrics, including average resection percentage and surgical duration, were recorded.
Results were compared to previously published data using the Phantom Omni for a similar surgical task.

Main Results:

Users achieved nearly identical average resection percentages when using the Leap Motion controller compared to the Phantom Omni.
Overall surgical duration was also comparable between the Leap Motion controller and the Phantom Omni.
The Leap Motion controller demonstrated comparable performance to the Phantom Omni in this specific surgical simulation.

Conclusions:

The Leap Motion controller is a viable interface for controlling continuum robots in endonasal pituitary surgery.
Its performance is comparable to existing systems, suggesting potential for broader application in minimally invasive surgery.
Further research should explore its utility in more complex surgical scenarios and with different robotic platforms.
