Abstract
A system includes (i) a solenoid valve, positioned between a handle of a probe, and an aspiration line coupled with the handle for aspirating fluids from the probe, the solenoid valve includes at least a solenoid coil and a plunger movable by the solenoid coil, (ii) a sensor, positioned between the handle and the aspiration line and configured to produce a signal indicative of a fluid metric in the aspiration line, and (iii) a controller, configured to identify, based on the signal, a vacuum surge in the aspiration line, and, in response to identifying the vacuum surge, to apply at least one current to the solenoid coil to selectively move the plunger between a first position and a second position, and to selectively maintain the plunger in the first position and the second position.
