The output laser beam is incidentally transmitted through the optical fiber 112 and operates as a pulse.

The optical fiber 112 guides the laser beam output from the laser oscillator 110 to the pen-type handpiece 170.

The parallel light converting unit 120 is located at the output end of the optical fiber 112 and converts the parallel beam so that the laser beam guided through the optical fiber 112 does not diverge. The parallel light conversion unit 120 is preferably composed of a convex lens.

The parallel light conversion unit 120 is mounted on the first mounting barrel 191 and provided inside the pen-type handpiece 170. The first mounting barrel 191 is inserted into the pen-type handpiece 170 by screwing, for example.

The cube polarizer 130 transmits the horizontal laser beam incident from the parallel light conversion unit 120 by horizontally linear polarization, and the light reflected from the scalp or the contact tip 160 as a target is laser oscillation unit. In order to block the feedback to the 110, the following reflection is reflected to the light transmission hole 192a.

The phase retarder 140 converts the horizontal linearly polarized laser beam incident from the cubic lighter 130 into light of rightly circular polarization and transmits the scalp and the contact tip 160. The left circularly polarized laser beam reflected from the laser beam is converted into light of vertically linear polarization and transmitted.

The phase delay unit 140 is preferably composed of a quarter-wave phase retarder.

The cube polarizer 130 and the phase delay unit 140 pass the laser beam output from the laser oscillation unit 110 to the scalp as a treatment target, but the light reflected from the scalp or the contact tip 160 as the treatment target is the laser oscillator 110. It serves to block the feedback.

The cube polarizer 130 and the phase delay unit 140 are connected to each other and inserted into the second mounting barrel 192 to be provided in the pen-type handpiece 170.

The second mounting barrel 192 is inserted into the inner circumferential surface of the pen-type handpiece 170 to be screwed, for example.

One side of the second mounting barrel 192 is formed with a reflective light transmission hole 192a. The reflective light transmission hole 192a is configured to allow the light reflected by the cube polarizer 130 to go out.

The absorption glass filter 132 is installed on the inner circumferential surface of the pen-shaped handpiece 170 to be parallel to the reflection light transmission hole 192a to absorb the reflection light passing through the reflection light transmission hole 192a.

The converging lens 150 passes through the phase delay unit 140 to converge the right circularly polarized laser beam and enter the contact tip 160.

The converging lens 150 is inserted into and fixed to the third mounting barrel 193. The third mounting barrel 193 is screwed to an inner circumferential surface of the pen-shaped handpiece 170 so that the converging lens 150 is mounted therein. have.

The pen-type handpiece 170 is a pen-shaped housing for accommodating the parallel light conversion unit 120, the cube polarizer 130, the phase delay unit 140, and the converging lens 150. It is a configuration to grip.

The pen-shaped handpiece 170 has a screw groove formed on an inner circumferential surface to screw the parallel light converter 120, the cube polarizer 130, the phase delay unit 140, and the converging lens 150.

The contact tip mount 180 is configured to be mounted inside the tip of the pen-type handpiece 170 to mount the contact tip 160.

The friction rubber 181 is a rubber material and is inserted into the rubber insertion groove 180a 'of the mounting hole 180a to firmly mount the contact tip 160.

Since the contact tip 181 is inserted and fitted to the friction rubber 181 of rubber material, there is a slight cushion even when the contact tip 160 presses the scalp, thereby protecting the procedure.

The contact tip 160 is configured to be in contact with the scalp that is a treatment target and to guide the scalp to be treated by refracting the laser beam incident from the converging lens 150 to focus on the treatment target. Therefore, the diameter of the laser beam irradiated to the scalp to be treated is smaller than the diameter of the contact tip 160 has the advantage that can be treated more safely for the scalp between the hair.

The contact tip 160 is partially inserted into the mounting hole 180a of the contact tip mount 180 and partially exposed to the inlet 170a of the pen-shaped handpiece 170.

The contact tip 160 is partially inserted into the friction rubber 181 is fitted.

Because of the friction action is inserted there is an advantage that the inserted contact tip 160 does not fall well.

In addition, the contact tip 160 is mounted to the mounting hole 180a so that it is not pushed back even when pressed.

The front edge of the contact tip 160 is formed in the chamfer (160a ') to be able to move smoothly without injuring the scalp to be treated even when contacted with the treatment target.

That is, the edge of the front surface 160a of the contact tip 160 in contact with the skin is not a right angle so that the wound does not occur even if it is moved in contact with the scalp.

Only the rear surface 160b of the contact tip 160 has an anti-reflective coating so that reflection does not occur in the laser beam of the oscillation wavelength.

In addition, the front surface 160a of the contact tip 160 has no coating for reflecting or transmitting the laser beam.

The contact tip 160 may be composed of, for example, a sapphire rod (quartz rod) or quartz rod (quartz rod) or BK7 (one of the borosilicate glass series) having a diameter of about 2 (mm).

The oscillation switch 172 is provided on one side of the outer circumferential surface of the pen-type handpiece 170 to turn on and off the laser oscillation of the laser oscillation unit 110.

On the other hand, all the optical elements (120, 130, 140, 150) except the front surface (160a) of the contact tip 160 has an anti-reflective coating so as not to reflect at the oscillation wavelength (for example, 1550 (nm)) of the laser beam of the laser oscillation portion In the case of the contact tip 160, only the rear surface 160b incident from the converging lens 150 has an antireflection coating with respect to the oscillation wavelength (for example, 1550 nm) of the laser beam of the laser oscillation unit.

The following describes the operation process of the scalp contact hair growth treatment pen laser device of the present invention having the configuration as described above.

The laser beam of a predetermined wavelength (for example, λ1) oscillated from the laser oscillation unit 110 is guided by the optical fiber 112 and is incident to the parallel light conversion unit 120 and parallel light by the parallel light conversion unit 120. The converted laser beam is incident on the cube polarizer 130.

The laser beam converted into a horizontal linear polarization state while passing through the cube polarizer 130 is converted into a laser beam of right circular polarization while passing through the phase delay unit 140.

The right circularly polarized laser beam is converged by the converging lens 150 and is incident to the contact tip 160 through the laser beam transmission hole 180b.

The laser beam incident on the contact tip 160 is refracted and focused on the scalp to be treated to transfer energy to the scalp.

Since the contact tip 160 is in direct contact with the scalp to be treated and the laser beam is transmitted to the scalp only through the contact tip 160, the contact tip 160 having a diameter of 2 mm or less can operate smoothly between hairs in the scalp. Hair damage does not occur during the procedure.

In the prior art, the laser is simply irradiated to the scalp, but the laser device according to the present invention uses a pen-type handpiece 170 and a contact tip 160 to irradiate and irradiate the laser onto the scalp so that it can be irradiated with the hair. It will not damage the hair roots.

When condensed and directly irradiated with the scalp, the condensed laser causes fine wounds to be generated on the scalp and the skin is regenerated as the wound is recovered. At this time, new hair roots are formed to enjoy a hair growth effect.

On the other hand, the spot size of the focused laser beam (spot size) is preferably to be several tens to hundreds (um), which can be implemented by adjusting the length of the contact tip (160).

Next, the operation of the laser beam reflected from the front surface (160a) of the scalp or contact tip 160 in the process of irradiating the laser beam to the scalp will be described.

Since there is no antireflection coating in the oscillation wavelength on the rear surface 160b of the contact tip 160, the reflection is not reflected on the front surface 160a of the contact tip 160.

The light reflected from the front surface 160a of the scalp or the contact tip 160 is incident to the phase delay unit 140 through the converging lens 150 while the polarization state is converted into the left circularly polarized light, and the phase delay unit 140 Is converted into a state of vertical linear polarization.

Since the cube polarizer 130 passes only the light of the horizontal linearly polarized light and reflects the light of the vertical linearly polarized light, the reflected light of the vertical linearly polarized light does not pass through the cube polarizer 130 but is reflected to the reflected light transmitting hole 192a. Reflected.

Therefore, the laser beam LY2 reflected from the front surface 160a of the scalp or the contact tip 160 cannot be fed back to the laser oscillation unit 110 during the procedure.

On the other hand, since the reflected light reflected by the reflected light transmission hole 192a is absorbed by the absorption glass filter 132, there is no damage due to scattering of the reflected laser beam.

In an embodiment of the present invention, for example, the contact tip 160 has a rod shape, but is not limited thereto. For example, a cavity is formed therein, or a through hole in a length direction. Of course, in the case of the tubular shape formed) is within the technical scope of the present invention.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.
