Hands-free controller for surgical microscope

Abstract

Systems and methods are disclosed for controlling a surgical visualization system using a hands-free (e.g., mouth, nose, and breath actuated) controller. An example system includes a microscope camera associated with the surgical system; a controller of the microscope camera; a processor; and a memory storing instructions for the processor. The controller may be separate from the microscope camera, and may comprise one or more joysticks. In some aspects, the controller may further include a pressure detector configured to detect pressure within a tube of a joystick. Also or alternatively, the controller may include a keyed proximity sensor to activate the controller when a surgeon is present. The processor may be configured to: receive a movement input based on a movement of the joystick along a Cartesian direction; and cause a corresponding movement of the microscope camera along the Cartesian direction.
