1. A disposable coagulator comprising:
- (a) a housing formed of an insulating material;
(b) a coaxial probe defining an inner electrode and an outer electrode and having a beveled end and secured within said housing, with said beveled end extending therefrom at one end of said housing;
(c) a pair of contact pins also secured within said housing but extending therefrom at its other end;
(d) a pair of wires connecting said inner and outer electrodes of said coaxial probe to said pair of contact pins;
(e) a wrapper containing said housing, said coaxial probe, said pair of contact pins, and said pair of wires in sterilized condition;
(f) said housing being formed, along its axial length, of two parts snap-fit to one another so as firmly to hold said coaxial probe therebetween, said two parts being injection formed of a plastic material and provided with complementary mating members snap-fit to each other so as to secure said two parts of said housing to one another along its said axial length; and
(g) an adhesive layer applied to at least one of said parts in the vicinity surrounding said coaxial probe, said adhesive layer cooperating with said two parts to firmly hold said coaxial probe in place.

Abstract
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.
