A microwave coagulating scalpel which simultaneously severs and coagulates highly vascular tissue is disclosed. The scalpel blade forms both a cutting edge and a microwave radiator loop, with the diameter of the loop related to the wave length of the microwave frequency, when the microwave energy is propogated in highly vascular tissue. A range of 100 MHz to 13,000 MHz is disclosed with preferential frequencies at 915 MHz, 2450 MHz and 5800 MHz. A means bolometer and threshold switch to de-energize the microwave source when the blade is removed from the highly vascular tissues also is disclosed.
