The invention discloses a pair of radio-frequency ultrasonic forceps. A knife tube sleeves a knife rod; a hole is formed in the knife rod; by virtue of a pin, the knife rod and the knife tube are fixed in a plastic shell; the knife rod and an energy transducer are connected by virtue of a threaded connecting rod; a rotating shaft is arranged on the plastic shell; corresponding holes are formed in a pair of metal forceps; the pair of metal forceps is connected to the plastic shell; a sealing cover sleeves the front end of the plastic shell; a plastic sheet is stuck on the plastic shell; and the pair of metal forceps communicates with a three-pin plug by virtue of a lead wire, and then the pair of metal forceps is connected to a nerve monitoring host machine by virtue of a socket and a host aviation plug. The pair of radio-frequency ultrasonic forceps is simple in structure and convenient to use; the pair of radio-frequency ultrasonic forceps integrates characteristics of a simple ultrasonic scalpel which is free from smoke, free from eschar and little in thermal injury on normal tissues in an operation and is simultaneously capable of promoting coagulation and ligation of small vessels, and meanwhile, the pair of radio-frequency ultrasonic forceps reserves the advantage of radio frequency in coagulating great vessels; and through a host machine, two types of energy, namely ultrasound and radio frequency, can be provided for the energy transducer as energy sources.
