An improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector is capable of several different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a trigger mechanism contained within the handle. The end effector includes a pair of curved jaw members and a blade assembly having a cutting blade at its distal end. The trigger mechanism is arranged to drive the blade assembly longitudinally within the elongate shaft such that the cutting blade protrudes between jaw members. In order to help trigger mechanism push the blade assembly around the curved jaws, the distal end of the blade has a graduated flexibility such that it can more easily bend to the shape of the jaw members. The distal end of blade may also be provided with a low friction coating.

A surgical instrument end effector assembly includes a first jaw member and a second jaw member. The second jaw member includes an ultrasonic blade body and first and second electrodes disposed on either side of the ultrasonic blade body and extending longitudinally along a majority of a length of the ultrasonic blade body. The ultrasonic blade body is adapted to receive ultrasonic energy from an ultrasonic waveguide. The first and second electrodes taper in width proximally to distally and are adapted to connect to a source of electrosurgical energy. The first jaw member is movable relative to the second jaw member between a spaced-apart position and an approximated position for grasping tissue therebetween.

An injectate delivery device for expanding tissue is provided. The injectate delivery device comprises: at least one fluid delivery tube comprising a proximal end, a distal end and a lumen therebetween; at least one fluid delivery element in fluid communication with the at least one fluid delivery tube lumen; a radially expanding element comprising the at least one fluid delivery element; a supply of vacuum constructed and arranged to cause tissue to tend toward the at least one fluid delivery element; and at least one control constructed and arranged to perform a function. The at least one control can be constructed and arranged to expand the radially expandable element and activate the supply of vacuum. Systems and method of injectate delivery are also provided.

A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.

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.

The present invention relates to an RF treatment apparatus including micro needles, a method of controlling the same, and a treatment method using the same according to the present invention have effects in that they can prevent damage to a tissue and perform optimized treatment because RF energy can be adjusted and applied based on a current-carrying area that belongs to a portion of the micro needles and that has been inserted into a tissue.

A testing device for an electrosurgical generator, including a first connection port and a second connection port for connecting the testing device to a patient circuit of the electrosurgical generator and including an apparatus for producing a direct voltage between the first connection port and the second connection port. The testing device is characterized in that an HF current path of the patient circuit, running from the first connection port to the second connection port, extends through the testing device and in that the apparatus for producing a direct voltage is fed by an HF current flowing through the HF current path.

A lighting device for attachment to a handheld electrosurgical instrument is disclosed, which includes an elongated housing having opposed proximal and distal end portions and defining an interior chamber containing a battery powered lighting assembly for illuminating a surgical site, the housing having a smoke evacuation tube associated therewith for removing smoke generated at the surgical site, wherein the smoke evacuation tube is adapted and configured to extend and retract relative to the distal end portion of the housing to accommodate different length end effectors associated with the handheld electrosurgical instrument.

A method of controlling a laser source to deliver laser energy through a medical device includes adjusting a laser source parameter including at least one of a laser power, a laser energy, a frequency, and a pulse width of the laser source. The laser source parameters are adjustable through a first action or series of actions on a foot pedal assembly operably coupled to a laser control unit. The method also includes activating the laser source. The activation of the laser source includes a second action or series of actions on the foot pedal assembly, and the second series of actions is different from the first action or actions.
