Variable backflow suction-hydraulic curet

A curet, comprising:

• a suction tube, said suction tube comprising a distal suction tip spaced apart from a proximal suction port, said suction tip comprising an entry orifice and at least one bleed orifice;
• at least one hydraulic tube coupled to said suction tube, each said hydraulic tube comprising a distal hydraulic tip spaced apart from a proximal hydraulic port, and configured to allow a fluid stream to flow through the hydraulic tube from the hydraulic port to the hydraulic tip and exit the hydraulic tube through the hydraulic tip, said distal hydraulic tip being positioned to direct at least a portion of a fluid stream exiting said hydraulic tip past at least a first orifice of said at least one bleed orifices, wherein at least some of the portion of the fluid stream is variably redirected by air flow through the first orifice;
• and
• at least one hydraulic flow diverter coupled to said suction tube proximate the first orifice, said diverter comprising a flow reversal vane positioned at least partially within the suction tube to variably intercept at least some of the portion of said fluid stream.

A curet, comprising:

• a suction tube, said suction tube comprising a distal suction tip portion spaced apart from a proximal suction port, said suction tip portion comprising an entry orifice and at least one bleed orifice;
• at least one hydraulic tube coupled to said suction tube, each such hydraulic tube comprising a distal hydraulic tip spaced apart form a proximal hydraulic port, and configured to allow a fluid stream to flow through the hydraulic tube from the hydraulic port to the hydraulic tip and exit the hydraulic tube through the hydraulic tip, said distal hydraulic tip being positioned to direct at least a portion of the fluid stream exiting said hydraulic tip past at least a first orifice of said at least one bleed orifice;
• and
• at least one hydraulic flow diverter coupled to said suction tube proximate said first orifice, said diverter comprising at least one mobilization flow vane directed substantially outward from said distal suction tip portion and positioned to intercept at least a portion of said exiting fluid stream.
