  • Patent number: 10849698
    Abstract: Various surgical tools with bailout mechanisms are provided that allow direct engagement with one or more actuators to provide rapid and effective bailout (such as release, reversal, and/or retraction) of surgical tools while minimizing the amount of force and/or time to complete the bailout. Robotic surgical tools generally have a housing and an elongate tool shaft extending from the housing and having an end effector on a distal end thereof. The housing has a plurality of actuators for causing various functions of the end effector, such as rotation, articulation, clamping, firing, stapling, etc. The housing attaches to a tool driver on a robotic arm that electromechanically drives the actuators to control the end effector. A bailout mechanism can extend from the housing into the elongate shaft and directly engage the actuators to apply a force thereto to retract an actuator.

  • Patent number: 10743872
    Abstract: Various systems and methods of controlling a surgical instrument are disclosed. The surgical instrument can include one or more sensors that are configured to detect or measure parameters associated with the use of the instrument and a display. A control circuit can be configured to detect whether the instrument is articulating, firing, clamping, and so on according to relationships between the detected parameters. The control circuit can further cause the display to display an image or sequences of images according to the particular operational state of the instrument. The images can provide alerts, instructions on how to use the instrument, or information detected by the one or more sensors, such as the position of the knife during transection.
