Abstract
A laser surgery smoke evacuator system is disposed within a small, thermally and acoustically insulated casing. The system includes a filter, a vacuum pump disposed downstream of the filter, an alternating current motor driven by an AC power source, a DC power supply energized by the AC source, an AC phase controller to vary the motor speed, a capacitor circuit to isolate the phase control from electromotive interference and a filter clog circuit. The DC power supply powers the phase controller and the capacitor and filter clog circuits. The AC phase controller is mounted next to an air intake in the casing for cooling the motor. The motor drives the vacuum pump which evacuates smoke from a laser surgery site, draws such smoke through the filter and exhausts clean air from the casing. A temperature controller disposed between the filter and pump is connected to the filter clog circuit, monitors the clogged condition of the filter and energizes an indicator on the casing to notify the user of the clogged condition of the filter.
