Abstract
Official abstract text for this publication.
A surgical instrument includes a drive member movable by a drive motor between a home position and an end of stroke. A mechanical stop is disposed at or near the end of stroke and is structured to increase resistance to movement of the drive member from a first position to a second position. A control system detects a current spike associated with the increased resistance and interrupts power to the drive motor.
First claim
Opening claim text (preview).
What is claimed is: 1. A surgical instrument comprising an electromechanical stop, where the surgical instrument comprises: a drive motor; a drive member movable by the drive motor through a drive stroke between a home position and an end of stroke, the end of stroke extending between a first position and a second position; a mechanical stop disposed at or near the end of stroke and structured to increase resistance to movement of the drive member through the end of stroke fro…
