Description

Distance Gauge Fixed Laser Handpiece

An embodiment according to the concept of the present invention relates to a laser handpiece, and in particular, a fixed distance gauge type that can easily change the beam shape of a laser beam in a simple and convenient way of rotating a cam rotate handle. It is about a laser handpiece.

Laser is a powerful and useful tool that can replace conventional invasive medical treatment. In particular, as the development of safe and non-surgical equipment increases with the development of medical lasers, a wide range of treatments from beauty to dermatology and surgery are emerging.

These medical lasers are used for the treatment of diseases through tissue incision, destruction, and removal in the medical field, and can be used in various departments for procedures and surgeries depending on the characteristics of the medium.

First, it is used for hair removal and tattoo removal.

Laser hair removal and tattoo removal are quickly becoming fashionable in the beauty industry. The removal method is non-invasive and utilizes the reaction that occurs between the laser's light wavelength and the hair/tattoo. While depilatory treatments stop or slow the growth of hair, tattoo removal uses multiple wavelengths and powers in turn to allow ink to be removed across the surface of the skin.

Second, it is used for dental procedures.

Dental lasers are powerful tools needed to treat periodontal disease while protecting the tissues and muscles of the oral cavity during procedures and other treatments. Compared to conventional dental treatment methods, lasers can improve the efficiency of the procedure.

Third, it is used for ophthalmic procedures.

Laser is one of the main tools commonly used in many ophthalmic procedures such as vision correction surgery such as LASIK. Laser therapy can be used for a variety of treatments, such as eye diseases, vision fixation, and repair of damaged retinas.

Fourth, it is used for plastic surgery.

The distinct wavelength of the laser light creates a localized energy spot for plastic surgery so that the laser light incident at a localized area reacts to body tissues such as skin tissue. Laser plastic surgery includes wrinkle improvement, skin growth and spot removal.

Of course, in addition to the uses described above, that is, for medical purposes, lasers are being applied to various industries such as semiconductors, displays, solar cells, and PCB manufacturing.

On the other hand, as described above, the laser has various uses, and in particular, recently, it has been widely used for medical purposes for skin use. In other words, lasers are widely used in dermatology, etc. to remove spots or blemishes, and for dermabrasion.

However, in order to increase the effect of laser treatment during this procedure, it is advantageous to change the shape of the laser, that is, the beam shape, to suit it when removing spots or blemishes and during dermabrasion. It is expected that a piece will be needed. However, considering the fact that domestic laser-related optical device or component manufacturers do not have a high market share due to the immaturity of the underlying technology and the economic downturn, the need for a laser handpiece with the above functions arises.
