Abstract
A surgical tool includes a drive housing, a shaft extending from the drive housing, an end effector at an end of the shaft and having opposing jaws and a cutting element, and an unclamp lockout mechanism. The unclamp lockout mechanism including a pawl rotatably mounted to the shaft and positioned proximal to a closure yoke operatively coupled to the shaft, the pawl being pivotable between a stowed position, where the pawl is received within an aperture of the shaft, and a deployed position, where the pawl protrudes out of the aperture, and a biasing device that biases the pawl toward the stowed position. When the pawl is in the stowed position, the closure yoke is movable to a proximal position over at least a portion of the pawl to open the opposing jaws. When the pawl is in the deployed position, the closure yoke is prevented from moving to the proximal position.
