Description

HAND PIECE TIP FRACTIONAL RESURFACING DEVICE}

The present invention relates to a handpiece tip for treating skin, and more particularly, concentrating a laser pulse into a microarray lens with a convex lens, and dividing the focused laser pulse into a fractional laser beam with a microarray lens to irradiate the skin. The present invention relates to a handpiece tip for skin treatment that can improve skin healing power and adjust the focusing of the laser to the skin by adjusting the distance of the lens, thereby reducing damage to the skin.

Human skin tissue is composed of the epidermis and the subcutaneous tissue below it, the epidermal layer having a stratum corneum acts as a biological barrier to the environment, the melanin cells that determine the skin color is present in the base layer. In addition, the lower subcutaneous tissue maintains the structure of the skin by the extracellular collagen acts as a support. Collagen is synthesized by fibroblasts and is a protein in which three polypeptides form a helix.

When injured, the body activates a complex remedy, of which fibroblasts are present under the skin and are activated to temporarily enter the extra cellular matrix (ECM) to cover the wound as soon as possible. Secrete. As fibroblasts slowly move around the matrix, attracting fibers to recombine the matrix, making the matrix more rigid, and because of the growth factors contained in the matrix that were initially soft, the fibroblasts expressed contractile proteins by the growth factors, At some point, the fibroblasts stop moving and turn into strong contractile cells, such as popeye, that settle in the matrix and attract the wound edges, resulting in scarring or uneven surface of the skin.

At this time, the collagen fibrous tissue is heated by a predetermined energy source, degeneration of the physical properties of the protein matrix occurs at a specific temperature, molecular binding of the matrix is broken, and the condition of the skin becomes even, and also activates the collagen layer. The elasticity of the skin can be restored.

Therefore, in recent years, the procedure for peeling or exfoliating rough skin is also frequently performed.

In particular, a method for exfoliation or exfoliation using a separate peeling device was also used for such peeling. In the case of such peeling device, the stratum corneum or acne of the skin was removed using ultrasound or laser.

7 is a diagram illustrating a laser irradiation state of the handpiece tip for treating skin according to an embodiment of the present invention.

1 to 3, a handpiece tip for treating skin according to an embodiment of the present invention includes a casing 100, a microarray lens 200, and a suction port 400.

In particular, the casing 100 forms an outer shape of the handpiece tip for treating the skin, and is formed to communicate with both sides along the axial direction.

Thus, the casing 100 serves to guide the laser beam irradiated to the skin treatment area through one side to the other side.

In particular, the casing 100 is applicable to a variety of shapes and materials.

The microarray lens 200 is formed inside the casing 100 to divide the laser pulses irradiated through one side of the casing 100 into a plurality of fractional laser beams. It serves to form a focal length in the skin corresponding to the treatment area.

4 is a perspective view showing the microarray lens 200 and the diffusion film 210, it is preferable that the microarray lens 200 has a diameter in the range of 20 ~ 200㎛.

At this time, when the diameter of the microarray lens 200 is smaller than 20 μm, the individual influence is too large, disadvantageous to the large area, and disadvantages in terms of manufacturing technology and manufacturing cost.

On the contrary, when the diameter of the microarray lens 200 is larger than 200 µm, the thickness of the diffusion film 210 increases, thereby causing the luminance deviation to easily occur, leading to deterioration in quality, and moire between the liquid crystal cells. ) It may cause a defect.

The height H ratio, that is, the H / R ratio range, of the microarray lens 200 to the radius of curvature R is preferably 0.5 to 1.2.

When the H / R ratio range is smaller than 0.5 or larger than 1.2, it is out of the optimal condensing range, resulting in a decrease in luminance.

That is, the microarray lens 200 is formed integrally with the diffusion film 210, it is preferably formed in an embossed pattern.

At this time, the emboss pattern serves to diffuse the incident light, the surface level should be able to satisfy the Ra (surface roughness) 0.5 ~ 3㎛, HDI (Height Distribution Index) 3 ~ 8㎛ range. It is not preferable that uniform diffusion becomes difficult when the Ra and HDI are out of range, and the total light transmittance is lowered when the range is exceeded, which causes variation by part of the film.

In addition, the microarray lens 200 is erected perpendicularly to the axial direction of the casing 100, irradiates a uniform laser in a direction perpendicular to the skin surface, and is formed in an embossed pattern, so that the depth of the microarray lens 200 is constant. It can efficiently transfer energy to the dermis and collagen zones.

In addition, since the beam angle is irradiated vertically with the same angle, the penetration depth of the skin is constant, and the spot size is the same.

In particular, the diffusion film 210 is preferably made of a thermoplastic resin material selected from the group consisting of methacryl resin, styrene resin, cycloolefin resin, polycarbonate resin, and mixtures thereof.

Of course, the microarray lens 200 may be variously applied to conditions such as wavelength and thickness and surface roughness according to the skin treatment conditions.

In addition, the laser pulse or the laser beam irradiated to the microarray lens 200 is preferably a carbon dioxide laser (CO ₂ laser) in the range of 10000 to 11000nm.

At this time, when the wavelength of the laser pulse or the laser beam is less than 10000 nm, since only heat is applied to the skin, collagen production is effective, but the effect on the skin surface is remarkably reduced.

On the contrary, when the wavelength of the laser pulse or the laser beam is greater than 11000 nm, the laser beam has high absorption of water and irritates the surrounding skin, thereby degrading collagen generating ability.

At this time, the wavelength of the laser pulse or the laser beam irradiated to the microarray lens 200 is preferably set to 10600nm.

Carbon dioxide laser of 10600nm wavelength (CO ₂ laser) is a well is removed (ablation) and heat (heating) of the dermis of the skin in combination consists can be seen a good therapeutic effect, and can be deep-skin removal than 1mm (deep dermal ablation) Three-dimensional treatment is possible.

On the other hand, the casing 100 forms a suction port 400 to be connected to the inner side communicating in the axial direction on the circumferential surface.

The suction port 400 is connected to an inhaler (not shown) and serves to induce foreign substances and odors generated during skin treatment by forced inhalation.

Thus, the room treating the skin can maintain a comfortable state.

And, although not shown, the suction port 400 is intermittent or the inhaler is turned on, off, so that the suction port 400 can execute or stop the suction function.

In addition, the casing 100 is preferably to form a leg 140 on the other side.

The leg 140 may be integrally formed on the other side of the casing 100 or detachably coupled by bolting or the like.

In particular, the leg 140 serves to secure the skin treatment area by reducing the contact area with the skin by preventing the casing 100 from coming into direct contact with the skin, and treating by keeping the distance between the casing 100 and the skin. It plays a role in keeping the degree constant.

Of course, the leg 140 can be variously modified, and is not limited to the number.

On the other hand, the casing 100 preferably forms the size adjusting lens 300 to increase the spot size of the divided laser beam.

The size adjusting lens 300 is disposed in line with the microarray lens 200, and is arranged in parallel with the axial direction of the casing 100.

Therefore, referring to FIG. 7, the fractional laser beam split through the microarray lens 200 may increase the energy delivered to the skin tissue with the same energy by the size adjusting lens 300.

At this time, the size adjusting lens 300 is preferably a flat convex lens.

That is, the size adjusting lens 300 has one side facing the microarray lens 200 in a flat form and the other side opposite to one side is convex.

In particular, the casing 100 includes a first barrel 110, a second barrel 120 and the adjusting unit 130.

In this case, the first barrel 110 is formed to communicate with both sides, and receives the first laser pulse through one side.

At this time, although not shown, the laser is generated from the laser generator.

Thus, the first barrel 110 is preferably detachably coupled to the laser generating device.

The first barrel 110 forms the microarray lens 200 therein.

In addition, the second barrel 120 axially inserts the first barrel 110 to one side.

That is, the diameter of the second barrel 120 is larger than the diameter of the first barrel 110.

In addition, the second barrel 120 is formed to be separated from the suction port 400 in the circumferential surface.

At this time, the suction port 400 may be formed in various ways, it is detachably coupled to the circumferential surface of the second barrel 120 by various methods such as bolting.

In FIG. 3, the solid line represents the irradiation direction of the laser, and the dotted line represents the movement path of the inhaled air.

The second barrel 120 includes a size adjusting lens 300 therein.

Of course, the size adjusting lens 300 may be formed in the first barrel 110 and the microarray lens 200 may be formed in the second barrel 120.

On the other hand, the adjusting unit 130 serves to adjust the insertion depth of the first barrel 110 with respect to the second barrel (120).

As a result, referring to FIG. 5, the distance between the microarray lens 200 and the size adjusting lens 300 is adjusted by the adjusting unit 130.

The reason why the distance between the microarray lens 200 and the size adjusting lens 300 is adjusted is to increase the skin treatment effect by adjusting the spot size of the irradiated laser beam.

Here, the adjusting unit 130 includes an elastic member 132, an elastic ball 134, a support member 136 and the adjusting groove 138.

Referring to FIG. 6, the elastic member 132 is inserted into the inner circumferential surface of the second barrel 120.

At this time, the upper side of the elastic member 132 is formed to be exposed to the inside of the second barrel (120).

Here, the elastic member 132 is preferably a coil spring.

The elastic ball 134 is elastically supported by the elastic member 132.

That is, when the elastic ball 134 is pressed by an external force, the elastic ball 134 is linked to the pressed and the elastic member 132 is compressed.

In addition, when the external force applied to the elastic ball 134 is removed, the elastic ball 134 is returned to the initial state by the elastic restoration of the elastic member 132.

In this case, the elastic ball 134 may be separated from the second barrel 120 and the elastic member 132.

Thus, the supporting member 136 serves to keep the elastic ball 134 in contact with the elastic member 132 at all times.

Here, the support member 136 is preferably fitted into the inner groove of the second barrel 120 is a snap ring to prevent the separation of the elastic ball 134.

Of course, the support member 136 may be attached to the inner surface of the second barrel 120 along the circumference of the insertion portion of the elastic ball 134.

In particular, the support member 136 supports the elastic ball 134 so as to partially protrude from the inner circumferential surface of the second barrel (120).

This is to allow the elastic ball 134 to contact the outer circumferential surface of the first barrel 110.

Here, the elastic ball 134 is preferably made of beads, it can be modified into a variety of materials.

In addition, a plurality of adjustment grooves 138 are formed in the circumferential surface along the axial direction of the first barrel 110 to change the position for accommodating the elastic balls 134, thereby adjusting the size adjusting lens 300 and the microarray lens ( It serves to regulate the interval of 200).

At this time, the elastic ball 134 is elastically accommodated in any one of the adjustment groove 138 by the elastic restoring force of the elastic member 132, accordingly, the size adjustment lens 300 and the microarray lens 200 gap It remains regulated.

In addition, when the user pulls or pushes the first barrel 110 or the second barrel 120, the elastic ball 134 is separated from any one adjusting groove 138 while compressing the elastic member 132, the first barrel. After moving along the outer circumferential surface of 110 is received in the other adjustment groove (138).

On the other hand, if the first barrel 110 is inserted into the second barrel 120 too much, the size adjustment lens 300 of the second barrel 120 may be damaged by hitting the first barrel (110).

Thus, the first barrel 110 preferably forms a flange 112 to limit the degree of insertion into the second barrel 120.

The flange 112 is detachably formed or integrally formed in the first barrel 110 to be in contact with an end portion of the second barrel 120.

Of course, the flange 112 may be modified in various shapes and various materials.

In addition, the first barrel 110 is preferably fixed to the microarray lens 200, the second barrel 120 is preferably fixed to the size adjustment lens 300.

In more detail, the first barrel 110 forms a first catching jaw 510 on the inside to support one edge of the microarray lens 200, and the other edge of the microarray lens 200 is a first barrel ( 110 is supported by a ring-shaped first retainer 520 that is screwed inside.

Here, the first catching jaw 510 may be integrally protruded from the inner side of the first barrel 110, or may be a star fitted into the first barrel 110.

In addition, the second barrel 120 forms a second catching jaw 530 inside to support one edge of the size adjusting lens 300, and the other edge of the size adjusting lens 300 is the second barrel 120. It is supported by a ring-shaped second retainer 540 that is screwed into the inside.
