Methods and apparatus for controlling the aerosol envelope generated by ultrasonic devices

摘要

Disclosed is a suction hood assembly that is attachable to an ultrasonic handpiece, as well as to a source of suction. The suction hood assembly includes a portion thereof that opens in an area adjacent the ultrasonic tip to provide an area of influence of the suction and thereby recover microdroplets of body fluids, matter and water mist. The suction can be used to control the size of the aerosol envelope generated when the water stream from the ultrasonic device is directed toward the ultrasonic-moving tip. The size of the aerosol envelope can be substantially reduced to a small area of operation, thereby minimizing the dispersion of germs, viruses and body fluids from the patient to the surgeon. The suction tube assembly is easily attached or removed from the ultrasonic handpiece, is easily manufactured, cost effective and thus is disposable.
