Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ultrasonic treatment, in particular to an ultrasonic treatment device. Background Art
[0002] At present, most ultrasonic treatment handles on the market require the transducer to move back and forth laterally in the treatment head to output energy for treatment. The transducer's lateral reciprocating motion is generally achieved by a screw motor drive. This method requires the motor screw to extend into the accommodating chamber of the treatment head. During the reciprocating motion of the transducer, the volume in the accommodating chamber will fluctuate, and the pressure in the accommodating chamber cannot be kept balanced. Therefore, a telescopic sleeve needs to be sleeved on the screw to buffer the volume fluctuation in the accommodating chamber, so as to balance the pressure in the accommodating chamber. Moreover, since the screw needs to be waterproof and sealed when it is extended into the accommodating chamber, the waterproof requirements are extremely high. Once leakage occurs, the ultrasonic treatment handle will not be able to continue to work, and there is a risk of damaging other parts of the handle. In addition, since the screw needs to extend into the accommodating chamber, the processing technology of the treatment head is relatively complicated and the cost is relatively high.
