ABSTRACT:
The irrigator aspirator instrument body has finger-operated valves for respective connection to sources of suction and irrigation. The body has connection ports on each end that it is reversible and has a clear polymer cannula attached in one of the ports for endoscopic utilization. The body is also transparent so that, during suction, complete aspiration can be observed. The other port carries a cautery rod which can be extended out of the cannula. The polymer cannula prevents capacitive charge coupling to the cannula.
