Abstract
A plasma tool adapted to emit high quantum energy inert gas atoms in a stream for cutting, liquefying, or evaporating material such as human tissue during surgical procedures. The apparatus comprises a source of inert gas, a plasma cell in communication with the inert gas source for imparting energy to the inert gas atoms and defined in part by a positive electrode and a negative electrode, at least one power supply electrically connected between the positive and negative electrodes, and means for directing the high quantum energy inert gas atoms at a target. The power supply initially provides an ionization voltage between the negative and positive electrodes to initiate a plasma from the inert gas in the plasma cell, and subsequently provides a pulsed voltage curve to sustain the plasma at a predetermined energy level. Methods for using the tool, including for performing surgical procedures, are also described.
