Hand wand for ultrasonic cosmetic treatment and imaging

A hand wand for use in cosmetic treatment, the wand comprising:

• a handle comprising an integrated receptacle configured for insertion of at least one of a first removable transducer module and a second removable transducer module, and an electrical cable,
• wherein said first removable transducer module and second removable transducer module are configured for interchangeable coupling to the handle with a spring pin connector,
• wherein the first removable transducer module comprises:
• a first ultrasonic treatment piezoelectric element configured to focus ultrasound at a first depth in a range between 3 mm and 4.5 mm below a skin surface with a first treatment frequency in a range of 1 MHz to 10 MHz at a first acoustic power in a range of 1 watt to 100 watts,
• a first printed circuit board configured for electrical connection to the spring pin connector, and
• a first storage device containing data for calibration or storage in a first sealed housing,
• the first sealed housing comprising a first acoustic fluid and a first acoustically transparent window,
• wherein the first ultrasonic treatment piezoelectric element is acoustically coupled to the first acoustically transparent window via the first acoustic fluid in the first sealed housing,
• wherein the second removable transducer module comprises:
• a second ultrasonic treatment piezoelectric element configured to focus ultrasound at a second depth in a range between 3 mm and 4.5 mm below the skin surface with a second treatment frequency in a range of 1 MHz to 10 MHz at a second acoustic power in a range of 1 watt to 100 watts,
• a second printed circuit board configured for electrical connection to the spring pin connector, and
• a second storage device containing data for calibration or storage in a second sealed housing,
• the second sealing housing comprising a second acoustic fluid and a second acoustically transparent window, wherein the second ultrasonic treatment piezoelectric element is acoustically coupled to the second acoustically transparent window via the second acoustic fluid in the second sealed housing,
• a movement mechanism comprising a shaft, a stepper motor, a scotch yoke, and a magnetic coupling, the movement mechanism configured to move at least one of the first ultrasonic treatment piezoelectric element and the second ultrasonic treatment piezoelectric element along the shaft to direct a ultrasonic treatment in a linear sequence of individual thermal lesions,
• wherein the movement mechanism further comprises an encoder disposed on the shaft, the encoder configured for measuring a position of the first ultrasonic treatment piezoelectric element along the shaft in the first sealed housing,
• an image button on the handle operably controlling an ultrasonic imaging piezoelectric element for providing ultrasonic imaging on a display,
• wherein the display comprises a graphical user interface,
• wherein the graphical user interface displays any one of the group of an operating condition, equipment status, and a system message;
• a treatment button on the handle operably controlling said first ultrasonic treatment piezoelectric element when the first removable transducer module is coupled to the handle to provide a first ultrasonic treatment function for providing a first ultrasonic treatment with the first removable transducer module at a first depth configured for treatment in at least one of the group consisting of:
• skin, superficial muscular aponeurotic system (“SMAS”), or fat,
• wherein the treatment button on the handle is configured for operably controlling said second ultrasonic treatment piezoelectric element when the second removable transducer module is coupled to the handle to provide a second ultrasonic treatment function for providing a second ultrasonic treatment with the second removable transducer module at a second depth configured for treatment in at least one of the group consisting of:
• skin, SMAS, or fat;
• wherein said first depth is different than said second depth, and
• wherein said first removable transducer module and second removable transducer module are configured to be operably coupled to said image button and said treatment button,
• wherein the movement mechanism is configured for travel through a liquid-tight seal,
• wherein the movement mechanism moves the first ultrasonic treatment piezoelectric element when the first removable transducer module is coupled to the handle, and
• wherein the movement mechanism moves the second ultrasonic treatment piezoelectric element when the second removable transducer module is coupled to the handle.
