Summary:A surgical tool includes a drive housing, a shaft extending from the drive housing and including an inner grounding shaft, an end effector coupled to the shaft and having opposing jaws, a firing rod extending within the inner grounding shaft and terminating at a cutting element, and an unclamp lockout mechanism provided within the drive housing and including a pawl rotatably mounted to the inner grounding shaft and pivotable between a stowed position, where the pawl is received within an aperture defined in the inner grounding 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 pawl is received within a cutout defined by the firing rod, and moving the firing rod distally overcomes the biasing device and urges the pawl to the deployed position.
