摘要：
A flow control system for an ultrasonic aspirator handpiece having an aspiration pathway having an inner nosecone operatively connected to the handpiece. A flow control mechanism is disposed over the inner nosecone defining a flow control channel therebetween. The flow control channel is operatively connected to the aspiration pathway. A control aperture of the flow control mechanism is configured for variable engagement by a digit of an operator between an open position and a closed position for corresponding variable adjustment of an aspiration flow rate.
