    摘要： A surgical instrument end effector includes a first jaw member and a second jaw member. The first jaw member has a first tissue contacting surface. The first tissue contacting surface is configured to self-interface and includes a first portion and a second portion. The first portion includes a first plurality of teeth having a first tooth pitch. The second portion includes a second plurality of teeth having the first tooth pitch. The second plurality of teeth is offset from the first plurality of teeth by ½ of the first tooth pitch. The second jaw member includes a second tissue contacting surface. The second tissue contacting surface is positioned to enable the first and second tissue contacting surfaces to interface with one another.

    摘要： A surgical robotic arm includes an instrument having a plurality of cables that are movable longitudinally and an end effector movable by the cables. The surgical robotic arm also includes a drive unit having a plurality of motors each of which is configured to move one of the cables and a plurality of torque sensors, each of which is configured to measure torque output by one of the motors. The surgical robotic arm also includes a controller configured to receive a torque measurement from each of the torque sensors and control each of the motors to apply a minimum torque to maintain a minimum tension on each of the cables based on the torque measurement from each of the torque sensors.

    摘要： A surgical instrument for use with and for selective connection to an instrument drive unit includes an end effector, an instrument drive connector including a plurality of drive assemblies, and a plurality of drive members in mechanical cooperation with the instrument drive connector and the end effector. Each drive assembly of the plurality of drive assemblies includes a drive screw including an elongated threaded body and a drive nut threadedly engaged with the elongated threaded body of the drive screw such that rotation of the drive screw results in longitudinal movement of the drive nut. Each drive member of the plurality of drive members includes a proximal end portion secured to a respective drive nut of one of the plurality of drive assemblies such that longitudinal translation of the respective drive nut causes longitudinal translation of the drive member to drive a function of the end effector.
