A disposable coagulator for the bipolar coagulation of blood vessels and/or tissue is disclosed. The disposable coagulator comprises a light-weight, electrically insulating housing, a coaxial probe defining an inner and outer electrode and having a beveled end and secured within the housing, and a pair of insulated leads coupling the probe to a source of variable rf power. The surface area of the inner electrode at the beveled end is substantially the same as the surface area of the outer electrode. Preferably, the housing is injection formed of a suitable plastic material in two parts designed to snap-fit to one another so as firmly to hold the probe within the housing, once assembled.
