PURPOSE: A handpiece for an ultrasonic device is provided to improve user convenience and to reduce operation time by forming an ultrasonic beam focusing area of a plane shape. CONSTITUTION: A handpiece for an ultrasonic device comprises a handpiece main body (110) and a cartridge (120) which is detachable from the handpiece main body. The handpiece main body includes body housing (111), an actuator (114) which is installed in the body housing and transfers a transducer in an axial direction, an operation button (116) mounted on the body housing, and a handpiece main board (112). The handpiece main board operates the actuator, supplies or intercepts power to a transducer (130), receives a signal sensed by the transducer, and transfers the signal to a controller main body. |
