摘要： A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a longitudinally-extending blade channel defined therein. An electrical cutting insert is releasably engageable within the blade channel of the jaw member such that the jaw member is transitionable between a mechanical cutting mode, wherein the electrical cutting insert is disengaged from the jaw member to permit reciprocation of a knife blade through the blade channel for mechanically cutting tissue grasped between the jaw members, and an electrical cutting mode, wherein the electrical cutting insert is engaged within the blade channel of the jaw member for electrically cutting tissue grasped between the jaw members.

摘要： Disclosed is an electrode (10, 60) for placement upon the skin of a patient (12) to deliver electrical pulses from medical electronic equipment (16) to the patient. The electrode includes (10, 60) an electrically conductive layer (24, 74) having a skin-facing side and an upper side. An impedance-decreasing layer (32, 82) is adjacent a substantial portion of the skin-facing side of the conductive layer (24, 74). A substantially electrically nonconductive backing layer (18, 68) is adjacent the upper surface of the conductive layer (24, 74), the backing layer (18, 68) being substantially impermeable to the impedance-decreasing layer (32, 82). A gas-permeable layer (20, 70) is between the backing layer (18, 68) and the conductive layer (24, 74). Finally, a vent (22, 72) is provided for venting gas formed between the impedance-decreasing layer (32, 82) and the conductive layer (24, 74) to the environment.

摘要： The present disclosure provides a bipolar forceps. The bipolar forceps includes a housing having a handle assembly including a movable handle and one or more shafts. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. A solenoid is in operative communication with the movable handle and operatively couples to a drive rod operatively coupled to at least one of the first and second jaw members for causing movement thereof. One or both of the first and second jaw members includes one or more teeth configured to engage one or more teeth located on the drive rod such that rotation of the solenoid imparts one of longitudinal and rotational movement of the drive rod such that at least one of the first and second jaw members moves between the open and closed positions.

摘要： Heating pattern uniformity is provided in a coaxial microwave hyperthermia probe by varying the open area in the outer conductor in an axial direction such that there is a maximum open area in the axial center portion. The variations may be provided by winding an outer conductor in a helical pattern with a variable pitch or by cutting openings of axially varying size in a solid outer conductor. The invention is applicable to both flexible and rigid probes.
