TECHNICAL FIELD [0001] The present invention relates to a handpiece for laser treatment and a lipolysis apparatus including the same. [0002]

The present invention relates to a handpiece for laser treatment and a lipolysis device.

Due to the westernization of abundant food and eating habits, the number of people classified as obese or overweight is increasing. On the one hand, as people become more concerned about health, there are also increasing numbers of people trying to lose weight in order to escape the risk of various diseases caused by obesity or overweight.

According to the World Health Organization Asia-Pacific Perspective (WHO), adult body mass index (BMI) is overweight when over 23 kg / ㎡ and overweight if over 25 ㎏ / ㎡. According to the guidelines of the Korean Endocrinological Society, Korean obesity is defined as over 25 kg / ㎡, and in the case of accompanying obesity - related diseases, it is recommended to treat it over 23 ㎏ / ㎡.

Obesity and overweight are mostly caused by increased body fat, so proper diet should be preceded by weight loss, but adult patients with a BMI greater than 40 kg / ㎡ or over 35 kg / ㎡ and having obesity related diseases Is recommended for treatment through obesity surgery.

However, since obesity surgery through surgical procedures necessarily entails bleeding and pain, continuous research and development is required for obesity surgery through non-surgical procedures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, embodiments of a laser-operated handpiece and a lipolysis device including the same according to the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals designate identical or corresponding components And a detailed description thereof will be omitted.

1 to 5, an apparatus for decomposing adipose tissue of a subject using a laser includes a main body 11, a laser generation unit 12, a laser delivery unit 13, A manipulation unit 14, a display unit 15, a control unit 16, and a fat decomposition apparatus 10 including a handpiece 100 are shown. In this case, the handpiece 100 includes the handpiece body 110, the reflector 120, the protrusions 130, the reflection layer 140, the diffusion unit 150, the translucent plate 160, and the cover 170 .

According to this embodiment, by forming a plurality of protrusions 130 on the inner wall of the reflection part 120 provided for reflecting and diffusing the laser in the handpiece 100 of the lipolysis device 10, So that it is possible to irradiate the treatment site of the subject, thereby improving the stability of the fat decomposition procedure and the fat decomposition efficiency.

Hereinafter, each configuration of the fat decomposition apparatus 10 according to the present embodiment will be described with reference to Figs. 1 to 5. Fig.

As shown in FIG. 1, the main body 11 may be provided with an operation unit 14, which may be composed of a plurality of operation buttons or the like, and a display unit 15 for displaying operation information. The main body 11 may be provided with a control unit 16 for performing operations based on instructions of a practitioner inputted by the operation unit 14 and for receiving and processing information from various sensors. In addition, although not shown, the main body 11 may be provided with a wheel for facilitating movement, a cradle for mounting the handpiece 100, and the like.

The laser generating unit 12 is installed in the main body 11 as shown in FIG. 1, and can generate a laser for the fat tissue disassembly procedure. In this case, the laser generating unit 12 may be a laser diode module (hereinafter, referred to as LD module) for generating a laser beam.

The laser generating unit 12 generates a laser to irradiate the fat cells distributed inside the skin to decompose fat. The wavelength and output of the laser generated by the laser generating part 12 and the type of the laser diode are not limited to the present invention, and various types of lasers can be used as long as they can be decomposed.

The laser can heat and decompose the cellulite and adipose tissue located beneath the dermal layer. For example, lasers are known to penetrate cellulite and adipose tissue in the dermis because they have a higher linearity than other light sources.

Also, lasers in the approximately 1060 nm to 1070 nm wavelength range are known to degrade cellulite and adipose tissue. Therefore, the lipolysis apparatus 10 according to the present embodiment can dissolve fat by penetrating the laser to the subject's skin tissue through the handpiece 100.

The principle of decomposing adipose tissue using a laser is known as follows. When a laser is shot on the subcutaneous fat layer, it is absorbed by an atomic group that selectively absorbs light of a specific wavelength (that is, a chromophore), and this energy generates heat, and the generated heat causes heat damage to fat cells, collagen, . The heat transferred to the adipocyte causes a hole of the same size as the diameter of the optical fiber in the cell membrane, so that the fat inside the adipocyte comes out of the cell, the adipocyte leaks out, and the remaining adipocyte is degraded.

The laser can be divided into a high-power laser and a low-power laser according to the size of the output. When a high-power laser is used, it is necessary to use a skin cooling means in order to prevent damage to the skin tissue caused by heat . That is, the cooling of the handpiece 100 by the cooling means can be performed together so that the handpiece 100 in contact with the skin during the procedure is not overheated.

As the laser to be used, it is preferable that the subcutaneous tissue in the region where the treatment is performed has a depth of penetration corresponding to the depth of the subcutaneous tissue at the thickest point or longer. The wavelength of the laser that meets the requirement to be able to penetrate into the skin tissue so as to heat the treatment site can be selected, for example, within the range of approximately 800 nm to 1200 nm. For example, in view of tissue permeability and relatively low absorption rate due to melanin and moisture, which are major pigments of the skin, a laser with a wavelength of approximately 1060 nm to 1065 nm can be selected.

In the case of this embodiment, in addition to the above-mentioned laser having a wavelength range of about 800 nm to 1200 nm for fat decomposition, a laser having a wavelength of 1.7 μm, which is known to have a relatively high light absorptivity due to a fat component, can be used. The invention is not limited thereto.

The laser may be stopped at certain time intervals during the procedure so that the temperature of the treatment site can be maintained at a temperature that allows lipolysis without skin damage. Alternatively, the activation and the stop of the laser may alternately be performed on the basis of the temperature detected value of the skin or handpiece 100 detected by the temperature sensor.

The cooling means includes a cooling unit for the laser generation unit 12 that performs cooling for the laser generation unit 12, a cooling unit for the handpiece 100 that performs cooling for the handpiece 100, A skin cooling part for performing cooling on the skin, and the like.

The cooling part of the handpiece 100 and the cooling part of the laser generating part 12 can cool the heat generated by the laser generating part 12 and the handpiece 100 generated by laser generation and irradiation using cooling water or the like.

In addition, the skin cooling part can be configured to spray the skin cooling gas to the skin. The skin cooling gas to be sprayed onto the skin may be atmospheric air or air cooled by a known refrigerant refrigeration cycle.

The laser transmitting unit 13 may be connected to the main body 11 as shown in FIG. 1 to transmit the laser generated in the laser generating unit 12 to the handpiece 100. The laser transmitting unit 13 may include an optical waveguide or an optical fiber for transmitting a laser beam and a cooling line for transmitting cooling water for cooling the handpiece 100 may be inserted into the laser transmitting unit 13.

Further, the laser transmitting portion 13 may be formed in a tubular structure connecting the main body 11 and the handpiece 100, and the tubular structure may be made of a flexible material having flexibility. As described above, since the laser transmitting portion 13 is made of a soft material, the handpiece 100 can be easily positioned at various portions of the subject's wrist and effective treatment can be performed.

1, the handpiece 100 may be connected to the laser delivery unit 13 to irradiate the laser delivered from the laser delivery unit 13 to the treatment site of the subject. The handpiece 100 may be fixedly attached to the body of the subject through the fixed unit. The fixation unit is for fixing the handpiece 100 on the skin tissue to be treated at the time of the operation and includes a frame on which the handpiece 100 can be mounted and a frame Belt.

The frame of the fixed unit may have various shapes and structures. For example, the frames may be arranged in a plurality of lines, or may be arranged in a line in a line according to various treatment areas such as the abdomen, side, or the like, or a plurality of frame units may be arranged in the upper and lower rows.

The handpiece 100 and the laser transfer unit 13 may be provided in a plurality of the same number in correspondence with each other. As shown in FIG. 1, for example, four handpieces 100 and four laser transmission parts 13 may be provided, and a plurality of handpieces 100 and laser transmission parts 13 may be provided Accordingly, it is possible to cover (170) a wide treatment area such as the circumference of the abdomen of the subject at a time, so that the fat decomposition procedure can be performed more quickly and efficiently.

Hereinafter, each configuration of the handpiece 100 according to the present embodiment will be described in more detail with reference to FIGS. 2 to 5. FIG.

The handpiece body 110 may have a substantially rectangular parallelepiped shape as shown in FIG. 3 and 4, an internal space is formed in the handpiece body 110, and a reflection unit 120, a diffusion unit 150, and the like may be installed in the internal space.

3 and 4, the diffusion unit 150 is installed on the upper part of the inner space of the handpiece body 110 to diffuse the laser incident on the handpiece body 110 while primarily diffusing the laser 120). The diffusing unit 150 may be composed of a plurality of lenses, for example, and a lens disposed at a position adjacent to the reflective portion 120 of the at least one lens may be a diffusion plate (not shown). The laser incident through the diffusion unit 150 as described above is refracted to primarily diffuse the laser irradiation range.

3 and 4, the reflection unit 120 reflects a laser incident on the handpiece body 110 through a laser transmission unit 13 installed in an inner space of the handpiece body 110, Can be diffused. The reflector 120 may be made of, for example, aluminum.

As described above, the laser incident on the handpiece body 110 is primarily diffused by the diffusion unit 150, and then can be secondarily diffused by the reflection unit 120. Accordingly, To the area corresponding to the exit area of the laser transmission path 122 of the laser light source 120, so that it can be uniformly irradiated onto the treatment site of the client.

4, a laser transmission path 122 may be formed in the reflection part 120, so that a laser incident on the handpiece body 110 is guided along the laser transmission path 122 to the surface of the recipient Can be delivered to the treatment site. The inner wall of the laser transmission passage 122 may be composed of a reflection surface 124 that is inclined outwardly so that the laser transmission passage 122 is enlarged toward the exit of the laser transmission passage 122.

That is, the reflection surface 124 may be formed to be inclined outward as it goes down, so that the cross-sectional area of the laser transmission path 122 increases from the entrance to the exit of the laser transmission path 122 inside the reflection part 120 . Accordingly, the laser transmission path 122 inside the reflection part 120 has a structure similar to a quadrangular pyramid.

Since the reflective surface 120 in the reflective portion 120 is inclined outwardly, the laser incident on the reflective portion 120 is reflected by the laser transmission path 122 while repeating reflection along the reflective surface 124 many times. Can be uniformly dispersed and diffused so as to correspond to the outlet area of the exhaust gas.

More specifically, the reflective surface 124 may include a first reflective surface 126 and a second reflective surface 128, as shown in FIG. The first reflective surface 126 may be located at an upper portion of the reflective portion 120 so as to be adjacent to the diffusion unit 150. The second reflective surface 128 may be positioned below the reflective portion 120 and connected to the first reflective surface 126 and may be formed to be more inclined outward relative to the first reflective surface 126.

The inclination of the second reflecting surface 128 with respect to the exit surface of the laser transmitting passage 122 is set to be larger than the inclination of the first reflecting surface 128 with respect to the exit surface of the laser transmitting passage 122, Is smaller than the inclination of the reflecting surface (126).

As described above, since the reflecting surface 124 is formed to have a dual structure with different slopes and the inclination of the second reflecting surface 128 on the lower side is made smaller, the laser incident on the reflecting portion 120 is reflected by the first reflecting surface 126 to enter the second reflecting surface 128 and disperse and spread over a wider range.

4, the protrusion 130 may be formed on the inner wall of the reflective portion 120 to increase the diffusion efficiency of the laser through the diffused reflection of the laser incident on the handpiece body 110. More specifically, a plurality of protrusions 130 may be continuously formed on the surface of the reflective surface 124 of the reflective portion 120, and the protrusions 130 may be formed by various processes such as blasting, etching, and the like.

Since a plurality of protrusions 130 are formed on the reflective surface 124 as described above, the laser incident on the reflective portion 120 causes irregular reflection on the surface of the plurality of protrusions 130 as shown in FIG. 4, Accordingly, the diffusion efficiency of the laser can be increased, and the uniformity of the laser in each region can be further improved within the irradiation range of the laser.

5, the ratio of the width w to the height h may be set to 1: 1 to 1:20. For example, the width of the protrusion 130 may be set to about 100 nm, and the height of the protrusion 130 may be set to 100 nm to 2 μm. The protrusion 130 may be formed in various shapes such as a cone or a polygonal pyramid. In FIG. 5, the protrusion 130 is illustrated as an example of a hemispherical shape.

The reflective layer 140 may be coated on the surfaces of the reflective portion 120 and the plurality of protrusions 130 as shown in FIG. The reflective layer 140 may be formed of, for example, a gold or silver material having a high reflectivity, and may be formed by a plating process or the like.

By forming the reflective layer 140 on the reflective surface 124 and the surface of the protrusion 130 as described above, the reflectivity of the laser incident on the reflective portion 120 can be increased. As a result, the laser reflection on the reflecting surface 124 and the laser diffused reflection on the surface of the projection 130 are doubled, and the uniformity in the irradiation range of the laser irradiated to the treatment site can be further improved.

As shown in FIGS. 2 to 4, the transparent plate 160 may be installed at a lower portion of the handpiece body 110 to emit a laser beam emitted from the handpiece body 110 to the outside. Therefore, the laser incident on the handpiece body 110 can be firstly diffused in the diffusion unit 150, secondarily diffused in the reflection unit 120, and then penetrated into the skin of the subject through the transparent plate 160 . As the transparent plate 160, for example, a transparent sapphire crystal may be used.

The cover 170 may be coupled to the lower surface of the handpiece body 110 to fix the transparent plate 160 as shown in FIGS. The cover 170 has a structure in which it is in direct contact with the skin of the person to be treated. The cover 170 may be provided with a temperature sensor, a contact seal, etc., which will be described later.

Meanwhile, the handpiece 100 may include a vibrating part, a temperature sensor, a touch sensor, a display lamp, and the like.

The vibrating part may be installed in the handpiece body 110 to generate vibration in the treatment area where the fat decomposition procedure is to be performed, thereby relaxing fat cells and improving the fat decomposition effect. The vibration by the vibrating part can be performed before or after the laser irradiation, or with the laser irradiation. Alternatively, vibration and laser irradiation may alternately be performed alternately. The vibrating part may be composed of, for example, a vibration motor, a piezoelectric element or the like.

The temperature sensor may be installed on the cover 170 of the handpiece 100 to detect the temperature of the treatment site so as to prevent damage to the skin tissue due to the heat generated by the laser. 170 to detect whether the handpiece 100 is normally in contact with the treatment site.

The measurement data measured by the temperature sensor and the touch sensor can be transmitted to the control unit 16 incorporated in the main body 11 and the control unit 16 analyzes the measurement data to determine whether the operation in the handpiece 100 Whether it is within a set temperature range, whether it is normally in contact with the skin tissue to be treated, and the like.

An indicator lamp capable of indicating the operation good or badness of the handpiece 100 may be provided outside the handpiece body 110 so that the operator can confirm whether the operation is performed safely and accurately through the indicator lamp.

Next, the fat ripping apparatus 10 according to another embodiment of the present invention will be described with reference to Figs. 6 and 7. Fig.

The laser generating unit 12, the laser transmitting unit 13, the operating unit 14, the display unit 15, the control unit 16, and the handpiece 100 (not shown) in the same manner as in the above- The handpiece 100 may also include a handpiece body 110, a reflector 120, a projection 130, a reflective layer 140, a diffusion unit 150, a transparent plate 160, And a cover 170, as shown in Fig. However, since the protrusion 130 formed in the reflective surface 124 differs from the above-described embodiment in terms of the size and density of the protrusion 130, the present embodiment will be described focusing on differences from these embodiments .

6 and 7, a portion of the plurality of protrusions 130 formed on the first reflective surface 126 is smaller than the remaining portion of the plurality of protrusions 130 formed on the second reflective surface 128 Lt; / RTI > That is, the plurality of protrusions 130 may be composed of two kinds of relatively different sizes (width and height), and the protrusions 130 having a relatively small size may be formed on the first reflective surface 126, Relatively small protrusions 130 may be formed on the second reflective surface 128. [

6 and 7, a portion of the plurality of protrusions 130 formed on the first reflection surface 126 is denser than the rest of the plurality of protrusions 130 formed on the second reflection surface 128 . That is, the small protrusions 130 formed on the first reflection surface 126 may be formed more densely and the large protrusions 130 formed on the second reflection surface 128 may be formed with a relatively low density.

By forming the protrusions 130 having a relatively small size on the first reflection surface 126 located at the upper portion in this manner at a high density, the first reflection surface 126 of the laser diffused through the diffusion unit 150, The uniformity and degree of the irradiation surface of the laser can be further improved.
