Abstract
Official abstract text for this publication.
A surgical spatula ( 10, 34 ) has a flat paddle ( 38, 62 ) and a handle extending away from a first end of the flat paddle ( 38, 62 ). The handle has a coaxial power feed ( 64, 130 ) which is connectable to receive energy from a microwave power source. The paddle ( 38, 62 ) contains a microwave conveying structure connected to the coaxial power feed ( 64, 130 ). The microwave conveying structure is enclosed at a front end of the paddle ( 38, 62 ) opposite to the first end so that microwave radiation is blocked from being emitted from the front end. The microwave conveying structure is open along a side of the paddle ( 38, 62 ) which extends away from the first end to permit a microwave radiation field to be emitted from that side.
