    Abstract: A vessel sealing instrument includes a housing having a shaft extending from a distal end thereof including an end effector assembly having opposing first and second jaw members operably coupled thereto. One of the jaw members moveable between open and closed positions for clamping tissue with a closure pressure within the range of about 3 kg/cm2 to about 16 kg/cm2. The jaw members are adapted to connect to a generator for providing energy thereto in accordance with a sealing algorithm. An anti-backdrive mechanism is associated with the end effector assembly and includes: a drive shaft coupled to a controller and a screw on opposite ends, the screw configured to engage one of the jaw members upon extension thereof to provide additional closure pressure therebetween. The drive shaft is rotatable by the controller to extend the screw in response to tissue expansion during sealing based on the sealing algorithm.

    Abstract: An electrosurgical system includes an electrosurgical instrument having an electrode with a polymeric dielectric coating; and an electrosurgical generator, which includes a power converter configured to generate RF energy; a sensor coupled to the power converter and configured to sense a parameter of the RF energy; and a controller coupled to the sensor and the power converter. The controller is configured to control the power converter to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating. The controller is further configured to determine whether the conductor breakthrough occurred based on the parameter; and execute a treatment algorithm based on a determination of the conductor breakthrough.

    Abstract: An enhanced haptic feedback system for medical diagnostics includes a laparoscope configured to be inserted into a body cavity to view tissue and obtain an image of the viewed tissue. An imaging device is configured to acquire physiological data about tissue, process the acquired physiological data, and output the processed data to a graphical user haptic interface (GUHI) capable of generating tangible sensations utilizing one or more haptic interfaces. The GUHI is configured to combine the image received from the laparoscope and the processed physiological data received from the imaging device to provide tangible sensations on both a front screen of the GUHI and a rear screen of the GUHI allowing a surgeon the sensation of feeling for abnormal tissue conditions between the surgeon's hands.

    Abstract: A cleaning fixture for a surgical instrument includes a handle receiving portion configured to receive a housing of a surgical instrument, a shaft receiving portion configured to receive a shaft and an end effector assembly of the surgical instrument, and a knife actuation assembly movably coupled to the handle receiving portion or the shaft receiving portion. The shaft receiving portion extends distally of the handle receiving portion. The knife actuation assembly is configured to selectively actuate a knife trigger assembly of the surgical instrument to advance a knife of the surgical instrument between jaw members of the end effector assembly thereof.

    Abstract: A clip applier includes a handle, an elongated shaft, an end effector, at least one surgical clip, a trigger, and an actuation mechanism. The trigger is configured to selectively translate at least a portion of the first jaw member relative to the second jaw member upon actuation thereof in a direction parallel to the longitudinal axis. The actuation mechanism is adapted to connect to a source of electrosurgical energy and is configured to selectively transmit energy to at least one of the at least one surgical clip.

    Abstract: A surgical energy system includes a first and second surgical instruments and a generator including a universal interface. The first surgical instrument includes a first instrument connector having one or more instrument couplers disposed in a first instrument coupler configuration. The second surgical instrument includes a second instrument connector having one or more instrument couplers disposed in a second instrument coupler configuration. The first and second instrument coupler configurations are different. The generator includes a universal interface including generator couplers arranged to provide generator coupler configurations at the universal interface. Each generator coupler configuration accommodates one of the first and second instrument coupler configurations in order to electronically couple the generator to a respective one of the first and second surgical instruments.

    Abstract: A surgical instrument includes a housing, a shaft extending distally from the housing, an end effector disposed at a distal end of the shaft, an actuator operably coupled to the housing, an actuation assembly, and a sensor module. The actuation assembly extends through the housing and the shaft and includes a distal end operably coupled to the end effector or a component associated therewith, a proximal end operably coupled to the actuator, and a spring. Actuation of the actuator manipulates the end effector or deploys the component relative thereto. The sensor module is disposed within the housing and configured to sense a property of the spring indicative of an amount the spring has been compressed. The sensor module is further configured, based upon the sensed property, to determine a condition of the end effector or the relative position of the component.
