Abstract
A robotic surgical instrument includes a housing having a shaft extending therefrom configured to receive a first end effector including jaw members moveable between a fully open position wherein the jaw members are spaced a maximum distance relative to one another and a closed position wherein a closure pressure between the jaw members is within a predetermined range. A drive rod actuates the first end effector upon translation thereof. The housing includes a spring compression assembly having proximal and distal hubs with the compression spring disposed therebetween. A jaw drive input rotates a drive gear to translate the distal hub relative to the proximal hub to compress the compression spring and actuate the end effector. Once the jaw members are fully open, the jaw drive input rotates a preset number of degrees to compress the compression spring and approximate the jaw members to a closure pressure within the predetermined range.
