    摘要: A robotic surgical tool includes an elongate shaft extendable through a handle that provides a drive input, an actuation system housed within the handle and operatively coupled to the drive input such that actuation of the drive input operates the actuation system, a rocker bar system arranged at a proximal end of the shaft and actuatable to articulate an end effector at a distal end of the shaft, and first and second drive cables extending along a portion of the shaft, each drive cable having a proximal end anchored to the shaft proximal to the handle and a distal end anchored to the shaft distal to the handle, wherein the drive cables are threaded through portions of the actuation and rocker bar systems such that operation of the actuation system acts on the drive cables and thereby actuates the rocker bar system to articulate the end effector.

    摘要: A robotic surgical tool includes a handle providing a first drive input and a second drive input, an elongate shaft extendable through the handle and having an end effector arranged at a distal end thereof, and a rack extending along a portion of the shaft and operatively coupled to a knife located at the end effector. Actuation of the first drive input transitions the rack between a locked configuration, where the rack is locked to the shaft, and a released configuration, where the rack is released from the shaft. Actuation of the second drive input with the rack in the locked configuration drives the rack and causes z-axis translation of the shaft through the handle. Actuation of the second drive input with the rack in the released configuration drives the rack relative to the shaft and thereby advances or retracts the knife at the end effector.

    摘要: A robotic surgical tool includes an elongate shaft extendable through a handle providing a drive input, a drive cable extending along a portion of the shaft and having a proximal end anchored to the shaft proximal to the handle and a distal end anchored to the shaft distal to the handle, an actuation system housed within the handle and operatively coupled to the drive input such that actuation of the drive input operates the actuation system, and a toggle mechanism arranged at a proximal end of the shaft and actuatable to close or open opposing jaws of an end effector arranged at a distal end of the shaft. The drive cable is threaded through portions of the actuation system and the toggle mechanism such that operation of the actuation system acts on the drive cable and thereby actuates the toggle mechanism to close or open the opposing jaws.
