Multipiece ultrasonic probe for liposuction

A device for removal of fatty tissue, comprising:

• a handpiece;
• a longitudinal probe having a proximal end and a distal end, said proximal end of said probe being attached to said handpiece;
• an ultrasonic means acoustically connected to said probe for imparting ultrasonic vibrations to said probe;
• and
• a tip mountable on said distal end of said probe, said tip having an acoustic impedance substantially greater than said probe;
• wherein:
• said tip is constructed from a material having a higher acoustic impedance than the material from which said probe is constructed;
• said probe is constructed from a metal material;
• and
• said tip is constructed from a plastic material.

A device for removal of fatty tissue, comprising:

• a handpiece;
• a longitudinal cylindrical probe having a proximal end and a distal end, said proximal end of said probe being attached to said handpiece;
• a piezoelectric ultrasonic transducer mounted in said handpiece, said ultrasonic transducer being acoustically connected to said probe for imparting ultrasonic vibrations to said probe;
• a generally cylindrical tip having a proximal end and a distal end, said proximal end of said tip being mountable on said distal end of said probe, said tip being constructed of a material having an acoustic impedance substantially greater than the material of said probe;
• a generally rounded contour formed on said distal end of said tip;
• and
• a jacket formed on a lateral surface of said tip, said jacket being acoustically connected to said probe, said jacket being constructed of a material having an acoustic impedance substantially the same as the material of said probe.

A device for removal of fatty tissue, comprising:

• a handpiece;
• a hollow cylindrical metal probe having a proximal end and a distal end, said proximal end of said probe being attached to said handpiece;
• a piezoelectric ultrasonic transducer mounted in said handpiece, said ultrasonic transducer being acoustically connected to said probe for imparting vibrations having an amplitude of approximately 0.002 to 0.005 inch and a frequency of approximately 20,000 to 40,000 Hz;
• a generally cylindrical plastic tip having a proximal end and a distal end, said proximal end of said tip being mountable on said distal end of said probe;
• a generally rounded contour formed on said distal end of said tip;
• and
• a metal jacket formed on a lateral surface of said tip, said jacket being acoustically connected to said probe.
