<P>PROBLEM TO BE SOLVED: To provide a surgical instrument configured to concurrently dissect and coagulate tissue. <P>SOLUTION: The surgical instrument 12 comprises a handle 30 and a shaft 40 extending distally from the handle. The shaft includes an outer hypotube, a lumen coaxially disposed within the hypotube and extending beyond a distal end thereof, a coaxial feed line coaxially disposed within the lumen and having an inner conductor and an outer conductor disposed coaxially about the inner conductor, and a coolant tube coaxially disposed between the lumen and the coaxial feed line to form an inflow conduit and an outflow conduit. The instrument further includes a dissecting head assembly body 50 coupled to a distal end of the shaft. The dissecting head assembly body includes a dielectric core having a substantially planar radiating surface and at least one non-radiating surface, a reflective coating disposed on the at least one non-radiating surface of the dielectric core, and a blade extending from the radiating surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
