    摘要： A surgical system having a surgical instrument having a connection portion including a connector connectable to a robot arm for mounting of the surgical instrument to the robot arm so that the instrument can be robotically manipulated by the robot arm to adjust a position of the instrument via a first communication from a remote central processing unit to the robot arm. A remotely actuated power pack is loadable into a compartment of the instrument for powering the instrument. The power pack has a first motor and a first engagement member operatively connected to the first motor and removably engageable with a first movable member of the instrument when the power pack is loaded into the instrument, the power pack effecting movement of the first movable member from a first position to a second position to effect a first function of the instrument.

    摘要： A surgical instrument includes a decoupling mechanism and a loading unit. The decoupling mechanism includes a driver coupling, an overstroke sled, a proximal driver, and a distal driver. The overstroke sled includes bosses configured to slidably engage slots of the driver coupling. The distal driver is coupled to a housing of the driver coupling for concomitant rotation therewith. A drive assembly of the loading unit is coupled to the distal driver such that rotation of the distal driver causes axial displacement of the drive assembly. The decoupling mechanism is transitionable between a first state, in which, rotation of the proximal driver of the decoupling mechanism rotates the driver coupling and the distal driver, thereby advancing the drive assembly, and a second state, in which, rotation of the proximal driver disengages the overstroke sled from the driver coupling to enable rotation of the overstroke sled relative to the driver coupling.

    摘要： A surgical robotic instrument comprising: a shaft; an end effector element; an articulation connecting the end effector element to the shaft, the articulation comprising: a first joint driveable by a first pair of driving elements, the first joint permitting the end effector element to rotate about a first axis transverse to a longitudinal axis of the shaft; a second joint driveable by a second pair of driving elements; a pulley arrangement around which the second pair of driving elements is constrained to move, the pulley arrangement comprising: a first set of pulleys rotatable about the first axis; and a second set of pulleys proximal to the first set of pulleys and comprising a first pulley rotatable about a second axis, and a second pulley rotatable about a third axis parallel to and offset from the second axis; and a clevis unit comprising two arms supporting the pulleys of the pulley arrangement, and a pulley guard extending from one of the arms for guarding one of the first and second pulleys.

    摘要： A needle driver can include a first jaw hosting a first shaft and a second jaw hosting a second shaft. The first shaft hosts a first roller and a first set of teeth. The second shaft hosts a second roller and a second set of teeth. The second jaw moves relative to the first jaw between an open position and a closed position. The first set of teeth meshes with the second set of teeth when the second jaw is in the closed position such that (a) the first set of teeth can drive the second set of teeth and (b) the first roller and the second roller can drive a needle therebetween when the first set of teeth drives the second set of teeth.
