Abstract: Disclosed are techniques for stapler reload detection and identification. A manipulator is configured to have an instrument mounted thereto. The instrument includes an end effector configured to receive a replaceable stapler cartridge. An actuator is drivingly coupled with the pusher member. A control unit is configured to control operation of the actuator to move the pusher member from a first position toward a second position; determine a distance that the pusher member moves from the first position toward the second position before a force limit for the actuator is exceeded; and determine, based on the distance that the pusher member moves, an operational status of the instrument relating to the replaceable stapler cartridge.

Abstract: Disclosed are techniques for stapler reload detection and identification. A manipulator is configured to have an instrument mounted thereto. The instrument includes an end effector configured for mounting of a replaceable stapler cartridge and a pusher member configured to articulate a staple pushing shuttle of the stapler cartridge to deploy staples from the stapler cartridge. An actuation mechanism is drivingly coupled with the pusher member. A control unit is configured to control operation of the actuation mechanism to move the pusher member from a first position to a second position, wherein at the second position, the pusher member makes contact with a portion of the staple cartridge or a portion of the end effector; determine a distance of movement of the pusher member from the first position to the second position; and determine, based on the distance of movement, an operational status of the instrument relating to the stapler cartridge.
