    Abstract: Provided in accordance with the present disclosure are systems for identifying a position of target tissue relative to surgical tools using a structured light detector. An exemplary system includes antennas configured to interact with a marker placed proximate target tissue inside a patient's body, a structured light pattern source, a structured light detector, a display device, and a computing device configured to receive data from the antennas indicating interacting with the marker, determine a distance between the antennas and the marker, cause the structured light pattern source to project and detect a pattern onto the antennas. The instructions may further cause the computing device to determine, a pose of the antennas, determine, based on the determined distance between the antennas and the marker, and the determined pose of the antennas, a position of the marker relative to the antennas, and display the position of the marker relative to the antennas.

    Abstract: A surgical instrument includes a housing, an elongated shaft extending distally from the housing, an end effector assembly, and a trigger assembly. The trigger assembly is disposed in mechanical cooperation with the housing and is configured to longitudinally translate a drive member. The trigger assembly includes a trigger, a gear assembly, a spool, a slider, and a flexible drive member. The trigger is disposed in mechanical cooperation with the gear assembly. The flexible drive member is configured to engage the gear assembly, the spool, and the slider. Movement of the trigger with respect to the housing results in movement of the flexible drive member with respect to the housing and longitudinal movement of the slider with respect to the housing.

    Abstract: An electrosurgical instrument includes a housing, an elongated shaft, and an end-effector assembly. The proximal end of the shaft is operably associated with the housing. The end-effector assembly is operably coupled to the distal end of the shaft and includes first and second jaw members. Each of the first and second jaw members includes a sealing plate and a bipolar electrode. Either one or both of the first and second jaw members is movable from a position in spaced relation relative to the other jaw member to at least one subsequent position wherein the sealing plates cooperate to grasp tissue therebetween. The electrosurgical instrument includes a semiconductor switch operably coupled to at least one of the sealing plates and at least one of the bipolar electrodes. The semiconductor switch is configured to enable user selection between energizing the at least one sealing plate or the at least one bipolar electrode.

    Abstract: An endoscopic forceps is disclosed including an end effector assembly having two jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween. Each of the jaw members is connectable to an electrosurgical energy source for conducting energy through tissue held therebetween. The jaw members are biased to the first position. The end effector assembly of the endoscopic forceps further includes a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the jaw members and operatively associated with the other of the jaw members. In use, withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to a second position and clamping of the tissue between the jaws.

    Abstract: An electrosurgical suction coagulator is disclosed having improved thermal insulation between the active electrode and adjacent tissue. In embodiments, passive insulation is used to control the transfer of thermal energy from an electrosurgical electrode into surrounding tissue. Braided, closed-sell foam material, and open cell foam materials may be used to thermally insulate the outer surface of a suction coagulator shaft from an inner electrode. In embodiments, a suction coagulator shaft includes an external covering formed from open-cell foam material, which may be saturated with a coolant, such as water or saline, to increase the thermal mass of the shaft. In other embodiments, active cooling delivers coolant to the operative site. In yet other embodiments, a suction coagulator shaft includes a cooling jacket through which coolant is passed to actively cool the instrument. The improved electrosurgical suction coagulator disclosed herein may have a reduced operating surface temperatures which may result in reduced risk of undesirable effects to adjacent tissue, and may result in reduced operative times and improved patient outcomes.

    Abstract: A method of performing a surgical procedure includes storing a software application on a memory associated with a computer, which when executed by a processor causes the software application to develop a model of a patient's anatomical structure, process images of the patient's anatomy, display the images of the patient's anatomy on a user interface associated with the computer, superimpose critical structures within the patient over the displayed images of the patient's anatomy, determine a location within the patient's body cavity where the images of the patient's anatomy were taken, and display the model of the patient's anatomical structure on the user interface, the displayed model indicating the determined location where the images of the patient's anatomy were taken.

    Abstract: An end effector assembly of a surgical device for shallow depth ablation includes first and second jaw members movable between open and closed positions and including hemicylindrical surfaces that cooperate to define a cylindrical cavity in the closed position for capturing tissue therebetween. At least one electrode array includes a plurality of first and second electrode portions disposed on or within at least one of the hemicylindrical surfaces and extending annularly at least partially thereabout. The plurality of first and second electrode portions are configured to be energized with electrosurgical energy at different potentials to thereby conduct electrosurgical energy between adjacent first and second electrode portions and through captured tissue to affect shallow depth ablation of captured tissue in the closed position of the first and second jaw members.
