Abstract
A robotic surgical instrument includes a housing having a shaft extending therefrom. A spring compression assembly is supported within the housing and includes: a proximal hub configured to secure a drive rod disposed therethrough, the proximal hub including teeth; a distal hub spaced from the proximal hub and including teeth; and a compression spring mounted between the proximal and distal hubs. A drive gear includes a proximal portion extending therefrom having threads disposed thereabout configured to engage the teeth of the proximal and distal hubs such that rotation thereof translates the hubs relative to one another and actuates the end effector assembly. A thumb wheel is included that has a portion exposed outside the housing for external manipulation thereof. The thumb wheel is selectively positionable between a disengaged position spaced relative to the drive gear and an engaged position to matingly engage the drive gear.
