ABSTRACT:
A variable backflow suction-hydraulic curet for mobilizing and evacuating tissue in a patient requiring such tissue removal. The variable backflow suction-hydraulic curet combines three modes of action to effect tissue removal while minimizing damage to underlying or adjacent tissue. The three modes of action are tissue mobilization through mechanical contact, through a variable pressurized fluid stream, and through suction-induced scavenging of mobilized tissue. Suction-induced scavenging of mobilized tissue occurs when a partial vacuum is applied to mobilized tissue through a suction tube within the curet. Movement of fluid and tissue particulates through the suction tube is enhanced by a variable pressurized fluid backflow through the suction tube which tends to further fluidize particulates and to increase the velocity of evacuation fluid flow. Variable features of the curet fluid flows are responsive to curet positioning and to vacuum applied to the suction tube vacuum port.
