Abstract
A surgical spatula has a planar transmission line for carrying microwave energy formed from a sheet of a first dielectric material which has first and second conductive layers on opposite sides thereof. The surgical spatula also has a coaxial cable for delivering microwave energy to the planar transmission line. The coaxial cable has an inner conductor, an outer conductor coaxial with the inner conductor and a second dielectric material separating the inner and outer conductors. The inner and outer conductors extend beyond the second dielectric to overlap opposite surfaces of the transmission line and electrically contact the first conductive layer and second conductive layer respectively. The width of the first and second conductive layers is selected to create an impedance match between the transmission line and the coaxial cable.
