Description

Ultrasonic generator {ULTRASONIC GENERATING DEVICE}

The present invention relates to an ultrasonic wave generator.

Ultrasound refers to a wave having a frequency of 20 kHz or higher, and is used in various ways to diagnose and treat an affected part in the medical field, as well as skin care.

In particular, High Intensity Focused Ultrasound (HIFU), which is a form of focused ultrasound at high intensity, is a non-invasive target of the skin without causing any damage to the skin surface, unlike laser and RF (Radio Frequency) high frequency waves. It can be focused on the area. As a result, a rapid temperature rise is induced in the target site of the skin, and coagulation necrosis of cells occurs without adverse effects on various affected areas of the skin. These necrotic cells are naturally removed by our body's repair mechanism for damaged parts.

Ultrasound generators that generate high-intensity focused ultrasound include Liposonix, which was developed by Solta Medical in the United States for the purpose of treating abdominal obesity in the human body.

Conventional ultrasonic wave generating device includes a cartridge housing, a handpiece detachably coupled to the cartridge housing, an ultrasonic wave generating module including a transducer that is mounted on a mount provided in the cartridge housing to generate ultrasonic waves, and a moving shaft for moving the ultrasonic wave generating module. , a driving unit for reciprocating the moving shaft, a first magnetic member provided on the mounter, and a second magnetic member provided on the moving shaft. Here, the moving shaft is connected to the mounter through magnetic coupling of the first magnetic member and the second magnetic member, and moves the ultrasonic wave generating module.

In the existing ultrasonic generator, when the moving shaft moves in the direction in which the ultrasonic generator module is pushed, the first magnetic member and the second magnetic member are in close contact with each other and the magnetic coupling of the first magnetic member and the second magnetic member is maintained. There was no problem that the ultrasonic wave generating module was stopped.

However, in the conventional ultrasonic generator, when the moving shaft moves in the pulling direction of the ultrasonic generator module, the first magnetic member and the second magnetic member are spaced apart from each other, and the magnetic coupling of the first magnetic member and the second magnetic member is released. Accordingly, there was a problem that the ultrasonic generating module was stopped. At this time, as the ultrasound output from the transducer of the ultrasound generating module is focused only on a specific part of the skin, there is a problem in that an image is generated on a specific part of the skin.
