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/cm.sup.2 to about 2 kg/cm.sup.2. The lever further movable to a seal position correlating to the jaw members closing about tissue with a pressure between about 3 kg/cm.sup.2 to about 16 kg/cm.sup.2 for sealing.

The procedure instrument includes an end effector for treating biological tissue by grasping biological tissue by opening and closing and imparting treatment energy to biological tissue, a fixed handle grasped by an operator, a movable handle for opening and closing the end effector by moving in a direction close to and away from the fixed handle, respectively, and a first switch provided inside the fixed handle and receiving a user operation for imparting treatment energy to the biological tissue from the end effector in response to the movement of the movable handle, and a second switch provided in a state of being exposed outside the fixed handle and receiving a user operation in response to the movement of the movable handle.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

A surgical instrument includes a shaft defining an axis, an end effector coupled to a distal portion thereof, a fixed handle coupled to a proximal portion thereof, a drive bar, a movable handle, and a linkage. The drive bar is disposed within the shaft and operably coupled to the end effector. The movable handle is movable relative to the fixed handle between open and closed positions and is coupled to the drive bar via a first pin on the axis. The linkage includes a first end portion coupled to the movable handle via a second pin and a second end portion coupled to the shaft via a third pin on the axis. In the closed position of the movable handle, the second pin is disposed in a near-over-center position relative to the axis to reduce a force necessary to maintain the movable handle in the closed position.

An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion, and a coring electrode positioned at the distal portion of the elongated body, where the coring electrode is at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway.

The invention generally relates to systems and methods for therapeutically modulating nerves in or associated with a nasal region of a patient for the treatment of a rhinosinusitis condition.

An electrosurgical device having an electrode with a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. An elongated hollow body has an internal cavity, a front end, a rear end, an external surface. An electrical circuit is arranged within the body. The second portion of the electrode is not surrounded by the hollow body. A first button is arranged on the external surface of the body for controlling a current flow at a first level. A vacuum tube is slidably engaged by the body. A vacuum outlet port is arranged near the rear end, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

A surgical instrument end effector assembly includes a first jaw member defining an insulative tissue-contacting surface and first and second electrically-conductive tissue-contacting surfaces disposed on either side of the insulative tissue-contacting surface. A second jaw member includes an ultrasonic blade body positioned to oppose the insulative tissue-contacting surface of the first jaw member. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position to apply a first grasping force to tissue disposed therebetween. A slider is movable, independent of the first jaw member, between a retracted position, wherein the slider is disposed proximally of the first and second jaw members, and an extended position, wherein the slider extends about the first jaw member and urges the first jaw member from the approximated position further towards the second jaw member to apply a second, greater grasping force to tissue.
