The Busse swivel handle comes pre-connected to clear 3/8" or 1/2" ID sterile tubing, and fits all popular styles of curettes, while the tubing fits or adapts to all aspirator pumps on the market. Made of clear, rigid, plastic, the handle rotates a full 360^°  for complete uterine cavity evacuation, with a molded point of reference to indicate the exact position of curette opening. A thumb-indexed ring slides easily over the suction vents for comfortable, positive control during the procedure.
