Abstract
A deployment and retraction mechanism for deploying and retracting a deployable component of a surgical instrument includes a gear assembly, a slider, and one or more actuators. The slider is translatable between a proximal position, corresponding to a storage condition of the deployable component, and a distal position, corresponding to a use condition of the deployable component. The actuator(s) is coupled to the gear assembly and is movable from an un-actuated position to an actuated position. The gear assembly is configured such that a full actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to the other of the proximal or distal positions while a partial actuation and subsequent release of the actuator(s) translates the slider from one of the proximal or distal positions to an intermediate position and back to the one of the proximal or distal positions.
