  • Publication number: 20240180609
    Abstract: An electrosurgical pencil includes a handle housing defining a fluid lumen and a central longitudinal axis. A nozzle defines a fluid lumen in fluid communication with the fluid lumen defined by the handle housing for evacuating fluid from a surgical site. The nozzle includes a slot configured to receive a nub protruding from the distal end portion of the handle housing to releasably couple the nozzle to the handle housing. An electrode configured to deliver electrosurgical energy to tissue has a proximal portion coupled to the handle housing and a distal portion extending through the fluid lumen defined by the nozzle. At least a portion of the electrode extends distally from a distal end of the nozzle. The electrode defines a central longitudinal axis offset from the central longitudinal axis defined by the handle housing.

  • Publication number: 20230046473
    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.

  • Publication number: 20230047599
    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.

  • Publication number: 20230047289
    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.

  • Publication number: 20220395315
    Abstract: A surgical instrument includes a handle assembly and a shaft portion extending distally from the handle assembly and configured to rotate relative to the handle assembly. The handle assembly includes an actuator and a gear that operably couples the actuator to the shaft portion. The gear is configured to transform a rotational motion of the actuator into a rotation of the shaft portion at a greater angular velocity than an angular velocity of the actuator.
