    Abstract: A medical device drive system can include a rotational input, a coupling member engaged with the rotational input, a first gear having an engagement feature sized and shaped to engage with the coupling member, and a second gear coupled with the first gear, the second gear coupled to a movable element. The system can have a first system state and a second system state. In the first system state the coupling member is not engaged with the engagement feature and the first gear rotates without moving the coupling member. In the second system state the coupling member is engaged with the engagement feature of the first gear and rotation of the rotational input turns the coupling member, the first gear, and the second gear to move the movable element.

    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: Stapler cartridges and surgical apparatus that include a stapler cartridge can include a knife that retracts into the stapler cartridge after cutting stapled tissue to prevent an operator being cut by the knife during replacement of the used stapler cartridge with a new stapler cartridge. A stapler cartridge includes a staple pushing shuttle, a knife member slidably coupled with the staple pushing shuttle, and a cartridge body. The staple pushing shuttle is slidably coupled to the cartridge body. The cartridge body includes a guide track engaged by the knife member and configured so that a cutting blade of the knife member protrudes from the cartridge body during a first portion of a distal movement of the staple pushing shuttle and the cutting blade is retracted into the cartridge body during a second portion of the distal movement of the staple pushing shuttle.

    Abstract: A drive shuttle is provided that includes a leader ramp mount that includes a longitudinal first axis; a first leader ramp that depends from (i.e. that physically couples to) a first side of the leader ramp mount; a pusher protrusion that depends from a second side of the leader ramp mount; a follower ramp mount; a follower protrusion that depends from the follower ramp mount; a first follower ramp that depends from the follower protrusion; wherein the first leader ramp, the pusher protrusion, the first follower ramp and the follower protrusion are disposed in relation to each another such that, in the first configuration, the pusher protrusion is spaced apart longitudinally from the follower protrusion by an offset amount and the first leader ramp is aligned longitudinally with the first follower ramp; and in the second configuration, the pusher protrusion contacts the follower protrusion and the first leader ramp is spaced apart longitudinally from the first follower ramp by the offset amount.

    Abstract: Systems and methods for grasp adjustment based on grasp properties include a computer-assisted device. The device includes a two-jawed end effector located at a distal end of the device, a drive unit for operating the two-jawed end effector, and an image processing unit. The image processing unit is configured to receive imaging data of the end effector and recognize the end effector and a material grasped by the end effector in the received imaging data. The device is configured to adjust a force magnitude limit or a torque magnitude limit of the drive unit based on the received imaging data. In some embodiments, the image processing unit is further configured to determine one or more of a position, an orientation, a size, or a shape of the material based on the received imaging data. In some embodiments, at least one jaw of the end effector includes fiducial indicia.

    Abstract: A knife member that can have a blade portion configured operation within a surgical stapling device. A first frame portion can extend from the blade portion to a first connection portion. A second frame portion can extend from the first frame portion to a second connection portion. At least one of the first and second frame portions can include a fused portion. The fused portion can be configured to fail when a predetermined amount of force is applied to the fused portion.
