A surgical system is disclosed including impedance sensors and a control circuit. The impedance sensors are configured to apply a therapeutic level of RF energy to tissue, sense a real time impedance of the tissue, sense a first tissue impedance based on an initial contact with the tissue, sense a second tissue impedance of the tissue without applying a therapeutic amount of RF energy to the tissue. The control circuit is configured to determine a control parameter of a motor based on the first tissue impedance and the second tissue impedance, determine a percentage of use of an end effector, detect a change of the real time impedance of the tissue, adjust the control parameter of the motor based on the change of the real time impedance and the percentage of use of the end effector, and control delivery of a therapeutic energy application to the tissue.

An electrosurgical pencil includes a housing having proximal and distal ends, the proximal end adapted to connect to an energy source and the distal end adapted to receive an end effector assembly therein, the end effector assembly defining a surface area along a length thereof. An activation switch is operably associated with the housing and is configured to deliver electrosurgical energy to the end effector assembly upon actuation thereof. An air control valve is operatively coupled to the activation switch and is configured to simultaneously deliver a gas from a gas source to the surface area around the end effector upon actuation of the activation switch. One or more vents are defined in the distal end of the housing and are configured to direct the gas towards the surface area of the end effector.

An electrosurgical instrument has dual zone smoke evacuation for providing efficient capture and evacuation of smoke generated during an electrosurgical procedure. A hand piece with a proximal and a distal end is coupled to a front piece having a distal opening leading into an interior conduit. An extendable section is at least partially disposed within the interior conduit and extends distally out of the distal opening of the front piece. The extendable section is selectively translatable within the interior conduit. A negative pressure source enables the capture and evacuation of smoke through both the extendable section and the interior conduit.

When surgical devices operate on tissue (e.g. cutting or ablating tissue), tissue and other debris is typically sucked away from the operating site along a suction pathway through the device. In some cases, this debris may accumulate at certain points within the device. This can lead to blockages forming in the suction pathway, which reduces the flow of debris through the device and hinders effective removal of debris from the operating site. The present invention addresses these issues by providing an apparatus which is configured to drive the end effector of a surgical instrument in an operational mode that causes tissue debris to be dislodged from the surgical instrument.

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 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 interactive control unit is disclosed. The interactive control unit includes an interactive touchscreen display, an interface configured to couple the control unit to a surgical hub, a processor, and a memory coupled to the processor. The memory stores instructions executable by the processor to receive input commands from the interactive touchscreen display located inside a sterile field and transmit the input commands to the surgical hub to control devices coupled to the surgical hub located outside the sterile field.

An electrosurgical device is adapted for use through a port and within a body cavity. The device includes a gas supply supplying gas to a distal tip and a valve to regular such supply, and an electric supply for supplying electricity to the distal tip. A pressure relief system is provided to regulate an outflow of gas from within the body cavity to prevent exceeding a predetermined pressure. The inflow of the gas through the valve and outflow of gas through the pressure relief system may occur simultaneously.

A surgical instrument includes a hand piece having a fixed branch and a displaceable branch for actuating a first tool and/or second tool, a guide device in which a force transmission device is arranged to be displaceable longitudinally and/or rotationally, the force transmission device coupled, on the proximal side, to the fixed branch and/or displaceable branch and coupled, on the distal side, to the first tool and/or second tool, and a connection device on which the guide device can be coupled to the hand piece in an insertable and detachable manner by a coupling simultaneously providing a holding force for holding the guide device in the connection device, a bipolar electrical contact on the distal side of the hand piece for parts of the instrument requiring energy, and degrees of freedom for longitudinal and/or rotational movement of the guide device and/or force transmission device.

A surgical instrument includes a housing having an elongated shaft with jaw members at a distal end thereof configured to treat tissue upon electrical activation thereof. A first handle is movable relative to the housing to move the jaw members relative to one another to grasp tissue therebetween. A switch is disposed on the housing and configured for activation by the first handle when fully actuated. A slider is disposed in the first handle and is movable between a first position configured to align a switch activation element on the first handle with the switch to activate the jaw members upon full actuation of the first handle and a second position wherein the switch activation element is misaligned with the switch such that full actuation of the first handle does not activate the jaw members.
