    Abstract: A medical device includes a shaft, an electrically insulative outer cover, an electrically insulative spacer, and a wrist assembly. The outer cover is positioned over an outer surface of the shaft and a distal end portion of the outer cover extends beyond a distal end surface of the shaft. The spacer comprises a first coupling portion, a second coupling portion, and a circumferential annular protrusion. The first coupling portion of the spacer is coupled to an inner surface of the shaft. The wrist assembly is coupled to the second coupling portion of the spacer. The annular protrusion of the spacer includes a shoulder and a seal surface. The shoulder of the annular protrusion is in contact with the distal end surface of the shaft, and the shaft is electrically isolated by the seal surface of the annular protrusion contacting the inner surface of the outer cover.

    Abstract: A tool member is rotatably coupled to a distal end portion of a shaft and includes a drive pulley and a coupling spool. A mechanical structure is coupled to a proximal end portion of the shaft and includes first and second capstans. The first and second capstans each include a first portion and a second portion. A distal portion of the cable is wrapped at least one revolution about the coupling spool. A first proximal end of the cable is wrapped about the second portion of the first capstan such that a second portion crosses over a first portion of the first proximal end of the cable. The second proximal end of the cable is wrapped about the second portion of the second capstan such that a second portion of the second proximal end of the cable crosses over a first portion of the second proximal end of the cable.

    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: Techniques for grasp adjustment include a computer-assisted device comprising a repositionable structure configured to support an end effector and one or more processors. The one or more processors are configured to receive one or more images of the end effector; determine, based on the one or more images, at least one of a first length between a proximal end of jaws of the end effector and a proximal end of a grasping zone, a second length corresponding to a length of the grasping zone, a third length between a distal end of the grasping zone and the distal end of the at least one jaw; or an angle between the jaws of the end effector; and adjust a force or a torque magnitude limit used to limit actuation of the end effector based on at least one of the first length, the second length, the third length, or the angle.

    Abstract: A medical device includes a chassis component having a bottom and an opening defined in the bottom, and a capstan including an upper portion, a lower portion, and a spool between the upper and lower portions. The upper portion of the capstan is supported within the opening of the chassis component. The spool comprises a cable wrap surface and a side wall opposing the bottom of the upper chassis. The side wall of the spool can optionally slope away from the bottom of the chassis component. The medical device can further include a cable guide and a cable. The cable extends from the cable guide to the cable wrap surface of the spool.

    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.
