ABSTRACT:
An instrument for delivering a variable pressure stream of fluid as a coherent jet. The instrument may be configured for holding in the hand of a user or for manipulation by machine control. The orifices may be oriented axially, transversely or obliquely. A deflector may be provided opposite the orifice to transform the jet stream into a harmless spray. The deflector may be slidable (in the axial mode) or pivotable (in the transverse mode) to ensure a small instrument profile. The instrument may be moldable allowing the user to reshape the jet tip into a desired configuration. The instrument may be remotely steerable and enable a user to selectively alter the direction of the jet without having to remove the instrument from the surgical site.
