The invention discloses an
electrocoagulation surgical instrument. The
electrocoagulation surgical instrument comprises a
handle, an
electrocoagulation head
assembly, and a flushing suction
assembly; a mounting cavity is formed in the
handle; the electrocoagulation head
assembly comprises an electrocoagulation head, a
metal conduit and an electrocoagulation wire, wherein the electrocoagulation head is arranged at one end of the
metal conduit, the other end of the
metal conduit extends into the mounting cavity, and the electrocoagulation wire extends into the mounting cavity and is connected to the metal conduit for transmitting electrical signals to the electrocoagulation head; the flushing suction assembly comprises a flushing
pipe, a suction
pipe, and a pipeline switch, wherein the flushing
pipe and the suction pipe extend into the
handle and are in communication with the metal conduit, and the pipeline switch is used for controlling the conduction and breaking of the flushing pipe and the suction pipe. The electrocoagulation
surgical instrument integrates the functions of electrocoagulation, flushing, and
smoke suction, and does not need frequently protruding into and out of the
abdominal cavity, so that the risk of
surgical infection of patients is reduced; the electrocoagulation surgical instrument can be operated by one hand, achieves rapid conversion of electrocoagulation, flushing, and
smoke suction, greatly reduces the time of instrument replacement, is convenient to operate, greatly improves the efficiency of
surgery, and improves the timeliness of treatment.
