Abstract: A surgical robotic system includes a robotic arm having an instrument drive unit and an access port configured to be secured to the robotic arm. The system also includes an instrument configured to couple to the instrument drive unit, where the instrument drive unit is configured to actuate the instrument. The system also includes a controller configured to: instruct the robotic arm to advance the instrument into the access port; instruct the instrument drive unit to calibrate the instrument inside the access port; determine a type of the access port during calibration of the instrument; and store the type of the access port in a memory.

Abstract: A surgical robotic system includes a robotic arm having a camera that is configured to output a video stream. The system also includes a surgical instrument coupled to the same or another robotic arm and a controller configured to receive the video stream from the camera and to calibrate the surgical instrument based on the video stream.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is operably coupled to the instrument housing and is configured to move the jaw members. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members, the handle having a lever configured to cooperate with the input to control the jaw members relative to movement of the lever. The lever moves between a homing position and a first position correlating to the jaw members closing with a pressure therebetween in the range of about 0.1 kg/cm2 to about 2 kg/cm2. The lever further movable to a seal position correlating to the jaw members closing about tissue with a pressure between about 3 kg/cm2 to about 16 kg/cm2 for sealing.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing with a shaft and first and second jaw members attached thereto movable to grasp tissue. An input is coupled to a jaw drive rod and is configured to move the jaw members. A strain gauge is coupled to the jaw drive rod and is configured to measure an amount of strain thereon and communicate the amount of strain to a robotic controller. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the jaw members. The handle includes a housing having components therein and a lever operably associated therewith such that movement of the lever relative to the housing correlates to movement of the jaw members. The components are configured to operably regulate the resistance of the lever in response to the amount of strain from the strain gauge.

Abstract: A robotic system includes an electrosurgical instrument having an instrument housing having a shaft with an end effector assembly and first and second jaw members attached thereto movable to grasp tissue. An input is configured to move the jaw members and is configured to operably couple to a torque sensor that measures the torque of the input during rotation thereof. A handle is remotely disposed relative to the instrument housing and is configured to communicate with the input for controlling the movement of the jaw members. A housing having a lever operably coupled thereto, houses components therein configured to operably connect to the input such that movement of the lever correlates to movement of the jaw members. The components are configured to regulate the resistance of the lever in response to the feedback from the torque sensor.
