Abstract

A handpiece for an ultrasonic device includes a handpiece main body and a detachable cartridge attached to the handpiece main body. The handpiece main body includes a main body housing, an actuator for axially transferring a transducer, an operating button, and a handpiece main substrate for operating the actuator according to the control of a controller unit, supplying power to the transducer according to on/off operations of the operating button, and receiving a signal detected by the transducer and transmitting the signal to the controller unit. The cartridge includes a cartridge housing, a transducer for generating ultrasound, a guide pin for guiding the transducer, a magnet, a slider for axially moving the transducer along the guide pin, a window for transferring the ultrasound to a patient, and a bellows for isolating liquid contained in the cartridge housing and helping easy transfer of the slider.

Claims

1. A handpiece for an ultrasonic device, comprising:

a handpiece main body; and

a cartridge attachable to and detachable from the handpiece main body, the handpiece main body comprising;

a main body housing;

an actuator installed in the main body housing for axially transferring a transducer;

an operating button mounted on the main body housing; and

a handpiece main substrate for operating the actuator according to the control of a controller unit, supplying and cutting-off power to the transducer according to on and off operations of the operating button, and receiving, as an input, a signal detected by the transducer and transmitting the signal to the controller unit, the cartridge comprising;

a cartridge housing;

a transducer built in the cartridge housing for generating point-focused or line-focused ultrasound;

a guide pin for axially guiding the transducer;

a magnet for power transmission for transferring the power of the actuator to the cartridge;

a slider for axially moving the transducer along the guide pin by the operation of the actuator;

a window formed on one side of the cartridge housing for transferring the ultrasound generated by the transducer to a patient; and

a bellows for isolating liquid contained in the cartridge housing and helping easy transfer of the slider.

2. The handpiece for an ultrasonic device according to claim 1, wherein the cartridge and the handpiece main body transfer the power of the actuator by the operation of the magnet for power transmission and connect a power supply and signals via a connector.

3. The handpiece for an ultrasonic device according to claim 1, wherein the handpiece main body further includes an LED substrate mounted in the main body housing for displaying the operating states, and the handpiece main substrate displays the operating states by turning on LEDs of the LED substrate.
