  • Publication number: 20260123983
    Abstract: A surgical instrument includes a shaft including a longitudinally extending slot, a drive element slidably disposed within the shaft, a drive link, and a body. The drive link includes a first portion external of the shaft and a second portion extending through the slot to engage the drive element within the shaft. The drive link defines a depth, a width greater than the depth, and a length. The depth of the drive link is less than the width of the slot to enable the drive link to extend through the slot. The width of the drive link is greater than the width of the slot. The body is disposed about at least a portion of the shaft. The first portion of the drive link is coupled to the body such that translation of the body along the shaft translates the drive element through the shaft.

  • Publication number: 20250143825
    Abstract: An end effector for use with a robotic system includes a proximal hub having a first upright support opposing a second upright support, a distal hub having a first upright support and a second upright support and pivotally coupled to the proximal hub about a first pivot axis, a first jaw member, a second jaw member, a first idler pulley, and a second idler pulley. The first and second jaw members are pivotally coupled to the first and second upright supports of the distal hub about a second pivot axis. First and second cable sets are configured to extend around the first and second idler pulleys and the first and second jaw members to rotate the first and second jaw members. The distal hub, the first idler pulley, and the second idler pulley are angled to produce fleet angles of about zero degrees.

  • Patent number: 11660109
    Abstract: A surgical end effector assembly includes first and second jaw members configured to grasp tissue. At least one of the jaw members defines a channel. A cutting element reciprocates through the channel to cut grasped tissue. The cutting element may include a first bevel defined along a first portion of a distal edge on a first side surface of the cutting element and a second bevel defined along a second portion of the distal edge on a second side surface of the cutting element. The first and second portions of the distal edge are sharpened to facilitate cutting tissue upon distal advancement of the cutting element. Alternatively or additionally, the cutting element may include a proximal body and a distal fin defining a height greater than a height of the proximal body and including a thinned portion defining a depression within a first side surface thereof.
