Abstract: A surgical device includes an elongated shaft, an end effector, and a wrist assembly. The wrist assembly includes a first outer link, a first inner link, and a second outer link. The first outer link is connected to the shaft and includes first gear teeth. The first inner link is pivotally coupled with the first outer link. The second outer link is pivotally coupled with the first inner link. The second outer link includes second gear teeth that interface with the first gear teeth and control orientation of the first inner link relative to the first outer link and the first outer link throughout a range of orientations of the wrist assembly.

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.
