Abstract
A debridement device having a controllable Lorentz-force actuator is disclosed. The debridement device includes a nozzle delivering a jet of debridement substance to a tissue and the jet is driven by the Lorentz-force actuator. The device may have a suction port for removing the debridement substance. A second Lorentz-force actuator can be used for each of the jet and suction. The first and second Lorentz-force actuators for the jet and suction can also be configured to provide for continuous jet injection and continuous suction. The device may include a second nozzle delivering a second jet of debridement substance to the region of tissue and the first and second jets may intersect and dissipate into a mist upon intersection to dissipate the kinetic energy of the jets. The Lorentz-force actuator may drive a reciprocating piston pump providing continuous pressure to the nozzles.
