1. A transducer module for use in an ultrasound treatment, comprising:
a sealed housing comprising an acoustic fluid and an acoustically transparent window,
a circuit board configured for direct electrical connection to a pin connector comprising one or more pins, wherein the circuit board is configured to be operably coupled to a detachable hand wand at a circuit board interface, wherein the circuit board interface is on an external surface of the transducer module,
an ultrasonic treatment piezoelectric element configured to focus ultrasoundenergy at a depth in a range between 3 mm and 9 mm below a skin surface with a treatment frequency in a range of 1 MHz to 10 MHz at an acoustic power,
wherein the ultrasonic treatment piezoelectric element is acoustically coupled to the acoustically transparent window via the acoustic fluid in the sealed housing, and
a movement mechanism comprising a shaft,
wherein the movement mechanism is configured to attach to a motor operably coupled to the detachable hand wand,
wherein the movement mechanism is configured to linearly move the ultrasonic treatment piezoelectric element along the shaft within the sealed housing to direct the ultrasound treatment in a linear sequence of spaced thermal lesions at the depth below the skin surface,
wherein the ultrasonic treatment piezoelectric element is configured to focus the ultrasound energy at the depth for treatment in at least one of the group consisting of: a dermis tissue, a fascia tissue, a muscle tissue, and a fat tissue,
wherein the transducer module is configured to detach from the detachable hand wand via the circuit board interface, which thereby permits a second transducer module to interchangeably attach to the hand wand after detachment from the transducer module.
