CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority from Korean Patent Application No. 10-2005-0017330, filed on Mar. 2, 2005, and Korean Patent Application No. 10-2006-0015778, filed on Feb. 17, 2006, which are incorporated herein by reference in the entirety. 
     BACKGROUND 
     The present invention relates to a lipolysis device using a low power laser, and more particularly, to a lipolysis device using a low power laser capable of non-invasively irradiating skin with a laser beam which may or may not be condensed through a lens or transparent window to obtain the same effect as lipolysis of adipose tissue exposed through incision using a conventional ultrasonic or low power laser. In addition, the lipolysis device includes a vacuum suction means to readily discharge liquefied fat discharged from an adipose cell and concentrated in a space between cell tissues through the groin area, where lymphatic vessels are abundant, and out of the body. Further the lipolysis device can stably contact human skin to break down fat and thus is convenient to use. Furthermore, the lipolysis device can break down subcutaneous fat by irradiating an abdominal region with a low power laser without skin damage or surgical operation, thereby effectively removing abdominal fat. 
     Generally, an apparatus for generating a low power laser includes a laser diode for emitting a laser having an output of 5 mW˜10 mW and a wavelength of 635 nm˜650 nm, and a low power laser diode driver for arbitrarily adjusting the amount of laser beam emitted from the laser diode. 
     Various apparatuses for obtaining a curative effect by irradiating spots on the body with a low power laser suitable for acupuncture or infected parts of the body. For example, Korean Utility Model No. 302173 discloses an electric mat for uniformly emitting a laser beam through a low power laser diode. Korean Utility Model No. 270882 discloses a waist belt including a laser generator having a laser diode for emitting laser light having a wavelength of 580˜980 nm to stimulate the lumbar, thereby performing finger-pressure treatment and therefore medical treatment of a disc. Korean Utility Model No. 274266 discloses a laser for medical treatment and an LED blanket capable of widening a curative range, for example, irradiation of spots on the body suitable for acupuncture, chronic article rheumatism, frozen shoulder, lumbago, cervical vertebral sprain, gout, wrench, bruising, arthritis, stress gastritis, and so on. Korean Patent No. 457964, issued to the present applicant, discloses a laser beam radiator capable of non-invasively irradiating blood in a blood vessel with a laser beam according to a position and a thickness of the blood vessel by adjusting a distance of the laser beam condensed through an optical lens, activating metabolism of a cell by stimulating a blood cell using a laser beam, increasing formation of capillary vessels to improve blood circulation, and increasing speed of tissue treatment to activate living organisms. 
     While another laser apparatus using a laser beam disposed in an array for providing use convenience is proposed to be adapted to various soft materials such as a chair, a hat, a bed, a belt, and so on, when the laser beam is disposed in the soft materials in an array, a red laser capable of being output appropriately to non-invasively break down fat (about, more than 30 mW) should be used. However, since the red laser requires a separate radiation structure, there is no way of breaking down fat by non-invasively irradiating a human body. 
     Meanwhile, in order to effectively treat obesity using a laser, Neira, et al. discloses a new suction lipectomy capable of liquefying fat during suction lipectomy using a low power laser [PLASTIC AND RECONSTRUCTIVE SURGERY, Sep. 1, 2002—Fat liquefaction: Effect of low-level laser energy on adipose tissue]. 
     Neira, et al.&#39;s paper is based on a test in which lasers having a wavelength of 635 nm, an output of 10 mW, and a total energy of 1.2 J/cm 2 , 2.4 J/cm 2  and 3.6 J/cm 2  are radiated onto adipose tissue extracted from 12 healthy women. As a result of the test, 4 minutes after laser exposure, 80% of the fat in the adipose cells is discharged, and 6 minutes after the laser exposure, 99% is discharged. Then, the discharged fat is gathered in a space between the adipose tissues. 
       FIG. 1  is an electron microscope photograph of a normal adipose cell at a magnification of 190,  FIG. 2  is an electron microscope photograph of an adipose cell after irradiation by a low power laser for 4 minutes, at a magnification of 190, and  FIG. 3  is an electron microscope photograph of an adipose cell after irradiation by a low power laser for 6 minutes, at a magnification of 190. As clearly shown in  FIG. 1 , generally, the normal adipose cell has a shape like a cluster of grapes. When the normal adipose cells are irradiated by the low power laser for 4 minutes, as shown in  FIG. 2 , some adipose cells discharge liquefied fat and lose their circular appearance. Portions designated by arrows in  FIG. 2  represent fat particles discharged from the adipose cells. When irradiated for 6 minutes, such variations are generated by most adipose cells, and therefore, as shown in  FIG. 3 , there is no adipose cell maintaining its original appearance, all reduced to liquefied fat. Portions designated by arrows in  FIG. 3  represent fat discharged from the adipose cells. 
     It was reported that energy of the low power laser acts to open a cell wall to discharge fat from the interior to the exterior of the adipose cell. 
     Using the fat liquefaction effect of the red laser on the basis of the test, suction lipectomy using a laser, in which the human body is irradiated from outside to break down fat and discharge the broken down fat from the body using a cannula (fine pipe), has been proposed. 
     Various methods of non-invasively irradiating skin covering a fatty area of a treatment target with a red laser beam to break down the fat of the adipose cells have been attempted. In order to irradiate a wider area for a short time, a device for forming a red laser beam with a line shape to scan the treatment target has been developed and put on the market. However, it is difficult to input a power of 10 mW and an energy density of 3.6 J/cm 2  required for lipolysis in the human body, thereby obtaining little practical effect. 
     BRIEF SUMMARY 
     The present invention solves aforementioned problems associated with conventional devices by providing a lipolysis device using a low power laser capable of non-invasively irradiating skin with a laser beam which may or may not be condensed through a lens or transparent window to obtain the same effect as lipolysis of adipose exposed through incision using a conventional ultrasonic or low power laser. 
     It is another aspect of the present invention to provide a lipolysis device using a low power laser including a vacuum suction means to readily discharge liquefied fat discharged from an adipose cell and concentrated in a space between cell tissues through the groin area, where lymphatic vessels are abundant, and out of the body. 
     In an exemplary embodiment of the present invention, a lipolysis device using a low power laser includes: a laser generator having a printed circuit board (PCB) provided with a power connector, a contact plate formed of a hard plate corresponding to the PCB and having a plurality of transparent windows or lenses uniformly disposed at one side surface, and a plurality of laser diodes inserted into the respective transparent windows or lenses disposed on the contact plate and electrically connected to the PCB; and a frame for accommodating the laser generator therein, in close contact with the skin, wherein the skin is irradiated with the low power laser to break down subcutaneous fat.

     In addition, the contact plate may be bent to have an oval surface suitable for contact with the skin, and the frame for accommodating the contact plate may be bent to have an oval surface corresponding to the contact plate. 
     Meanwhile, the frame may have grips formed at appropriate places on one or both sides thereof. 
     Alternatively, other frames may be connected to hinges pivotally installed at both ends of the frame, respectively. 
     In another exemplary embodiment according to the present invention, a lipolysis device using a low power laser includes: a laser generator having a printed circuit board (PCB) provided with a power connector, a contact plate corresponding to the PCB and having a plurality of transparent windows or lenses uniformly disposed at one side surface, and a plurality of laser diodes inserted into the respective transparent windows or lenses disposed on the contact plate and electrically connected to the PCB; a frame for accommodating the laser generator therein; and a vacuum suction means having a shape conforming to a shape of the frame, disposed at a front surface of the frame, and having a suction port, a vacuum line connected to the suction port through a vacuum suction part, and a vacuum pump connected to the vacuum line, thereby being in contact with the skin, wherein the lipolysis device is suctioned to the skin and then the skin is irradiated with the low power laser to break down subcutaneous fat. 
     The vacuum suction means may be detachably connected to the frame. 
     In addition, the contact plate may be flexible. 
     In still another exemplary embodiment according to the present invention, a lipolysis device using a low power laser includes: a vacuum suction means having a suction port, a vacuum line connected to the suction port through a vacuum suction part, and a vacuum pump connected to the vacuum line, a coupling part having a coupling hole projecting from an upper center of the vacuum suction means by a predetermined extent; and a laser generating module having a PCB connected to the vacuum suction means to receive power through a cable, a laser diode electrically connected to the PCB, a transparent window or lens appropriately installed adjacent to the laser diode, upper and lower fixtures that are mutually detachable and accommodate the PCB, the laser diode, and the transparent window or lens, and a cover installed outside of the upper and lower fixtures, wherein the lipolysis device is suctioned to the skin, and then the skin is irradiated with the low power laser to break down subcutaneous fat and stimulate a scalp to accelerate hair growth. 
     The upper and lower fixtures may have male and female threads threadedly engaged with each other at its lower periphery and its upper periphery, respectively, a hooking threshold may be formed at an appropriate place at an inner periphery of the upper fixture to be engaged with the PCB, and a groove may be formed at an appropriate place at a lower inner periphery of the lower fixture to be engaged with the transparent window or lens.

     Meanwhile, the vacuum suction means having the laser generating module may include a relay, formed at an appropriate location thereon, branching off into a plurality of connection vacuum lines connected to the vacuum suction part, and each of the connection vacuum lines may be connected to another vacuum suction means having a laser generating module through a vacuum suction part. 
     Alternatively, one connection vacuum line of the connection vacuum lines branching off from the relay may be connected to the vacuum pump, and another connection vacuum line may be connected to another relay. 
     As can be seen from the foregoing, the lipolysis device using a low power laser in accordance with the present invention is capable of non-invasively irradiating skin with a laser beam through a lens or transparent window by condensing the laser beam or as they are to obtain the same effect as lipolysis of adipose exposed through incision using a conventional ultrasonic or low power laser, though a laser irradiation treatment method is changed to the non-invasive method using transmission characteristics of the laser, including a vacuum suction means to readily discharge liquefied fat discharged from an adipose cell and concentrated to a space between cell tissues through the groin region, in which lymphatic vessels are abundant, to outside the body, stably contacting with human skin to break down fat to provide user convenience. 
     In addition, the lipolysis device using a low power laser has advantages of breaking down and liquefying subcutaneous fat by irradiating an abdominal region with a low power laser to discharge the subcutaneous fat from the body without skin damage or surgical operation, unlike conventional suction lipectomy, thereby effectively removing abdominal fat. 
     Furthermore, the lipolysis device using a low power laser includes a vacuum suction means for readily discharging liquefied fat, discharged from an adipose cell, concentrated to a space between cell tissues, and suctioned to the outer skin, through the groin region, in which lymphatic vessels are abundant, outside the body, thereby maximizing lymph drainage of naturally discharging excessive fat in the human body to easily cure abdominal obesity, without using an invasive discharge means such as suction lipectomy.

     DETAILED DESCRIPTION 
     The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. 
       FIG. 4  is an exploded perspective view of a laser generating unit of a lipolysis device using a low power laser in accordance with the present invention,  FIG. 5  is a view of a laser irradiation distribution range of a lipolysis device using a low power laser in accordance with the present invention, and  FIG. 6  is a perspective view of a lipolysis device using a low power laser in accordance with the present invention. 
     As shown, a lipolysis device  1  using a low power laser in accordance with the present invention includes a laser generating unit  10  and a frame  30 . 
     The laser generating unit  10  includes a printed circuit board (PCB)  12  provided with a power connector  11  for receiving power, a contact plate  14  corresponding to the PCB  12  and having a plurality of transparent windows or lenses  13  disposed on its one surface at predetermined intervals, and a plurality of laser diodes  15  inserted into the respective transparent windows or lenses  13  disposed on the contact plate  14  and electrically connected to the PCB  12 . 
     The frame  30  is formed to accommodate the laser generating unit  10  therein. In this process, the laser generating unit  10  is accommodated in a front surface of the frame  30  to irradiate the skin of a user with a laser beam. 
     Meanwhile, a plurality of fastening holes  17   a  and  17   b  are formed at appropriate locations on the contact plate  14  to fasten the PCB  12  to the contact plate  14  by means of a plurality of fastening bolts  16 . Specifically, the plurality of laser diodes  15  are installed at the PCB  12 , the plurality of fastening holes  17   a  and  17   b  are formed at appropriate locations on the contact plate  14  and the PCB  12  to fasten the PCB  12  to the contact plate  14  after inserting the laser diodes  15  into the transparent windows or lenses  13  of the contact plate  14 , and then, the fastening bolts  16  are fastened through the fastening holes  17   a  and  17   b , thereby securely fastening the PCB  12  to the contact plate  14 . 
     In addition, the plurality of lenses or windows  13  are preferably disposed at the contact plate  14  in an array, and the number of laser diodes  15  corresponding to the number of the lenses or windows  13  disposed at the contact plate  14  are preferably inserted into the lenses or transparent windows  13 . 
     While the plurality of lenses or transparent windows  13  disposed at the contact plate  14  are uniformly disposed in the embodiment of the present invention, providing that the laser is radiated to readily break down subcutaneous fat of a user after contact with the skin, the lenses or transparent windows  13  may be irregularly disposed at the contact plate  14 . 
     In this process, the contact plate  14  may have various shapes such as circular, rectangular, and so on. 
     Meanwhile, each laser generated from the laser generating unit  10  has a low output of 10 mW˜100 mW. That is, in order to break down subcutaneous fat by irradiating the skin of a user with a laser beam, each laser generated from the laser diodes  15  of the laser generating unit  10  has a low output of 10 mW˜100 mW, in consideration of attenuation in the human body. 
     As described above, each laser generated from the laser generating unit  10  has a low output of 10 mW˜100 mW, the laser generating unit  10  has a plane array structure in close contact with the user&#39;s skin, and a plurality of laser diodes  15  apply lasers, respectively, thereby ensuring invasive force into the user&#39;s skin and enabling the laser to be uniformly radiated onto a larger area of the skin to simultaneously break down subcutaneous fat. 
     For this purpose, preferably, the contact plate  14  has a curved surface to be in smooth contact with the skin in an area such as the abdomen, in which subcutaneous fat is concentrated, and the frame  30  for accommodating the contact plate  14  also has a curved surface conforming to a shape of the contact plate  14 . 
     While the contact plate  14  in accordance with an embodiment of the present invention has a curved surface, it may be formed of a flexible material to conform to various parts of the user&#39;s body. 
     In addition, the contact plate  14  in contact with the user&#39;s skin may be formed of a hard material to be readily fastened and installed at the lipolysis device, thereby facilitating contact with the user&#39;s skin. 
     Meanwhile, the contact plate further includes a heat dissipating plate for dissipating heat generated from the laser diodes  15 . That is, since a large amount of heat is generated when laser radiation is radiated from the laser diodes  15  installed at the contact plate  14 , the contact plate  14  further includes the heat dissipating plate in order to distribute the heat and cool the contact plate  14 . While the contact plate  14  in accordance with an embodiment of the present invention further includes the heat dissipating plate, the contact plate  14  may be formed of a heat dissipating material. 
     Here, grips  31  for a user to grip the frame  30  by hand are formed at appropriate places on one or both sides of the frame  30 . While the frame in accordance with an embodiment of the present invention includes the grips  31  formed at appropriate places on one or both sides of the frame  30 , providing that the user can conveniently grip and use the frame  30 , the grips  31  may be formed at appropriate places on upper and lower sides of the frame  30 . 
     Meanwhile, it is also possible to further include a positioning means for a doctor or a user to change a position of the frame  30  in vertical and horizontal directions at a rear surface of the frame  30 , but a description of this will be omitted. Specifically, a well-known positioning means  35  can be installed at a rear surface of the frame  30  to move the frame  30  having a means for contacting a human body in vertical and horizontal directions at a user&#39;s convenience, similar to medical equipment that is freely movable by a doctor. Therefore, the frame  30  can be readily moved to a part of the user&#39;s body as required by the user. 
     Hereinafter, a method or process of using a lipolysis device using a low power laser in accordance with the present invention will be described. 
     First, a doctor licensed to practice medicine at a medical institution holds grips  31  installed at the frame  30  of the lipolysis device  1  using a low power laser, and moves the lipolysis device  1  to be in close contact with the skin of a patient at a place where fat is to be broken down. 
     Then, the laser generating unit  10  is driven to generate a laser through the laser diodes  15  and irradiate the skin with the laser. 
     At this time, the laser with a low output of 10 mW˜100 mW is generated through each laser diode  15  of the laser generating unit  10 , and passes through a plurality of transparent windows or lenses  13  to be radiated onto the skin where subcutaneous fat is to be broken down. 
     As described above, the subcutaneous fat is broken down by the laser radiated onto the user&#39;s skin in an area such as the abdomen and so on, and the broken down fat is removed from the body by surgical operation. 
     Here, the lipolysis device  1  using a low power laser in accordance with the present invention uses a red laser together with an infrared laser. The red laser requires an output of 30 mW or more at 635˜680 nm, and the infrared laser requires an output of 50 mW or more at 780˜980 nm. Hereinafter, the red laser and the infrared laser may be adapted without discrimination. 
     As described above, each radiation range of the low power laser generated and radiated from each of the laser diodes  15  has an oval shape as shown in  FIG. 5  so that there is no overlapping between the radiation ranges and the laser is radiated onto the corresponding contact part only to break down subcutaneous fat. 
       FIG. 7  is a perspective view of an embodiment of a lipolysis device using a low power laser in accordance with the present invention, in which several components are different from  FIG. 6 . 
     Referring to  FIG. 7  together with  FIGS. 4 and 5 , a lipolysis device  1  using a low power laser in accordance with an embodiment of the present invention includes hinges  33  pivotally installed at both side ends of a frame  30 , and other frames  30 ′ are connected to the hinges  33 , respectively. 
     That is, the hinges  33  are installed at both sides of the frame  30  of the lipolysis device  1  using a low power laser, and other frames  30 ′ are connected to the hinges  33 , respectively, thereby forming a shape surrounding a user&#39;s abdomen or waist. 
     As described above, the frames  30  and  30 ′ having the laser generating units  10  are continuously and pivotally connected to each other by the hinges  33  so that the frames  30  and  30 ′ can be in three-dimensional contact with the user&#39;s abdomen, waist-side, or the like. 
     While the frame  30  of the embodiment includes the hinges  33  at both sides, and the other frames  30 ′ are connected to the frame  30  by means of the hinges  33 , since the other frames  30 ′ include the hinges  33 , and the other frames  30 ′ are continuously installed by means of the hinges  33 , the lipolysis device can be used to break down subcutaneous fat regardless of the user&#39;s body shape. 
     While the contact plates  14  installed at a front surface of the respective frames  30  and  30 ′ connected by the hinges  33  have a planar shape in the present embodiment, they may be bent into various curved shapes so that the laser can be readily radiated onto the user&#39;s abdomen and waist-sides. 
     In addition, the contact plate  14  may have various shapes such as rectangular, circular, or oval, or may be formed of a flexible material to be manipulated into various shapes. 
       FIG. 8  is a schematic view of another embodiment of a lipolysis device using a low power laser in accordance with the present invention. 
     Referring to  FIG. 8  together with  FIGS. 4 and 5 , a lipolysis device  1  using a low power laser in accordance with an embodiment of the present invention further includes a vacuum suction means  50 , in addition to a laser generating unit  10 , and a frame  30  for accommodating the laser generating unit  10 . 
     That is, the lipolysis device  1  further includes the vacuum suction means  50 , in addition to a printed circuit board (PCB)  12  provided with a power connector  11 , a contact plate  14  corresponding to the PCB  12  and having a plurality of transparent windows or lenses  13  disposed on its one surface at predetermined intervals, and a plurality of laser diodes  15  inserted into the respective transparent windows or lenses  13  disposed on the contact plate  14  and electrically connected to the PCB  12 . 
     Here, while the contact plate  14  may further include a heat dissipating plate to radiate heat generated from the laser diodes  15 , the contact plate  14  may be formed of a heat dissipating material. 
     The vacuum suction means  50  has a shape conforming to a shape of the frame and disposed at a front surface of the frame  30 , and has a suction port  51  in appropriate contact with a user&#39;s skin, a vacuum line  56  connected to the suction port  51  through a vacuum suction part  54 , and a vacuum pump  57  connected to the vacuum line  56 , thereby forming a predetermined vacuum pressure. 
     In this process, the vacuum pump  57  sucks air in the suction port  51  in contact with the user&#39;s skin through the vacuum suction part  54  to bring the suction port to a predetermined vacuum pressure. The air removed by the vacuum pump  57  is moved through the vacuum suction part  54  and the vacuum line  56 . 
     While the vacuum suction means  50  of the present embodiment may be integrally formed with the frame  30  at a front surface of the contact plate  14  of the lipolysis device  1  using a low power laser, as shown in  FIG. 9 , it may alternatively be detachably coupled to the frame  30  of the lipolysis device  1  using a low power laser. 
     In this process, preferably, the vacuum suction means  50  is detachably coupled to the frame  30  of the lipolysis device  1  using a low power laser by means of fitting or threaded engagement. 
     In accordance with the above-described structure and shape, it is possible to fasten or separate the vacuum suction means  50  to or from the lipolysis device  1  using a low power laser depending on a doctor or user&#39;s need. 
     Meanwhile, a step (not shown) suitable for close contact with the user&#39;s skin is preferably formed at one side periphery of the vacuum suction means  50 . 
     Hereinafter, a method or process of using a lipolysis device using a low power laser in accordance with the present invention will be described. 
     First, a doctor licensed to practice medicine at a medical institution brings a vacuum suction means of a lipolysis device  1  using a low power laser into close contact with a user&#39;s skin for breaking down fat. That is, a suction port  51  of the vacuum suction means  50  is brought into close contact with an appropriate part of the user&#39;s skin. 
     As described above, after the suction port  51  of the vacuum suction means  50  is brought into close contact with the user&#39;s skin, the vacuum pump  57  brings the interior of the suction port  51  to a predetermined vacuum pressure so that the skin over the subcutaneous fat to be broken down is in close contact with an inner periphery of the suction port  51 . 
     After the skin covering the subcutaneous fat to be broken down is brought into close contact with an inner periphery of the suction port  51  to be positioned adjacent to the laser generating unit  10 , the laser generating unit  10  is driven to generate a laser through the laser diodes  15  and irradiate the skin with the laser. 
     That is, after attaching the suction port  51  of the vacuum suction means  50  to the user&#39;s abdomen, the vacuum pump  57  sucks out the air in the suction port  51  to bring the skin into close contact with the inner surface of the suction port  51 , and the laser is radiated onto the skin in an area such as the abdomen to break down subcutaneous fat. 
     At this time, a low power laser with an output of 10 mW˜100 mW is generated through each laser diode  15  of the laser generating unit  10 , and the generated laser passes through the transparent windows or lenses  13  to be radiated onto the skin, thereby breaking down subcutaneous fat. 
     As described above, the subcutaneous fat is broken down by the laser radiated onto the user&#39;s skin suctioned by the vacuum suction means  50 , and the broken down fat is removed from the body by surgical operation. 
     In this process, since the subcutaneous fat broken down by the laser generated from the laser diodes  15  is located beneath the skin suctioned in the suction port  51  by means of the vacuum state in the suction port  51  of the vacuum suction means  50 , when the vacuumed suction port  51  is moved in a scan manner, the broken down subcutaneous fat moves too. 
     It is also possible to discharge the subcutaneous fat through the groin region after moving the subcutaneous fat broken down by the laser by the aforementioned method through the suction port  51  of the vacuum suction means  50 . 
       FIG. 10  is an exploded perspective view of another embodiment of a lipolysis device using a low power laser in accordance with the present invention, and  FIG. 11  is a cross-sectional view of an assembly of a vacuum suction means and a laser generating module of a lipolysis device using a low power laser in accordance with the present invention. 
     Referring to  FIGS. 10 and 11  together with  FIGS. 4 and 5 , a lipolysis device  1  using a low power laser in accordance with an embodiment of the present invention includes a vacuum suction means  50  and a laser generating module  70 . 
     The vacuum suction means  50  includes a suction port  51  in contact with an appropriate part of a user&#39;s skin for breaking down subcutaneous fat, a vacuum line  56  connected to the suction port  51  through a vacuum suction part  54 , and a vacuum pump  57  connected to the vacuum line  56  to form a predetermined vacuum pressure. 
     In this process, the vacuum pump  57  sucks out the air in the suction port  51  in contact with the user&#39;s skin through the vacuum suction part  54  to bring the interior of the suction port  51  to a predetermined vacuum pressure, and the air sucked out by the vacuum pump  57  is moved through the vacuum suction part  54  and the vacuum line  56 . 
     Meanwhile, in order to install the laser generating module  70 , a coupling part  59  has a coupling hole  52  projecting upward from an upper center of the suction port  51 . 
     The laser generating module  70  includes a PCB  71  for receiving power, a laser diode  72  electrically connected to the PCB  71 , a transparent window or lens  73  disposed adjacent to the laser diode  72 , upper and lower fixtures  74  and  75  for accommodating the PCB  71 , the laser diode  72 , and the transparent window or lens  73 , which are detachable from each other, and a cover  76  installed outside the upper and lower fixtures  74  and  75 . 
     In addition, a male threaded part  74   a  and a female threaded part  75   a  are formed at a lower periphery of the upper fixture  74  and an upper periphery of the lower fixture  75  to be threadedly engaged with each other, a hooking threshold  74   b  is formed at an inner periphery of the upper fixture  74  to be engaged with the PCB  71 , and a groove  75   b  is formed at a lower periphery of the lower fixture  75  to be engaged with the transparent window or lens  73 . 
     In this process, by fastening and releasing the male threaded part  74   a  and the female threaded part  75   a  formed at the upper and lower fixtures  74  and  75 , an interval between the laser diode  72  and the transparent window or lens  73  can be adjusted. 
     Meanwhile, the PCB  71  is connected to a cable  71   a  to receive power, and an insertion hole  76   a  for inserting the cable  71   a  therethrough is formed at an upper part of the cover  76 . 
     In addition, in order to fasten the vacuum suction means  50  and the laser generating module  70  to each other, female and male threaded parts  53  and  76   b  are formed at an inner upper side of the coupling hole  52  of the suction port  51  and an outer periphery of the cover  76 . Further, the upper and lower fixtures  74  and  75  may be formed of a thermal interface material for radiating heat generated from the laser diode  72  of the laser generating module  70 . 
     Meanwhile, the suction port  51  has a manual negative pressure release hole  58  for manually releasing a vacuum or negative pressure in the suction port  51 , i.e., by the finger of a doctor or a user. 
     While the suction port  51  of the present embodiment has a single manual negative pressure release hole  58 , providing that the vacuum or negative pressure in the suction port  51  can be readily released, the suction port  51  may have at least two manual negative pressure release holes  58 . 
     In addition, while the manual negative pressure release hole  58  has a circular shape, the manual negative pressure release hole  58  may have various shapes such as oval, rectangular, or the like, and may also have various diameters. 
     In this process, an annular insertion groove  58   a  is formed at an end of the suction port  51 , and balls  58   b  are rotatably inserted into the insertion groove  58   a . Specifically, in order to readily move the suction port  51  under the vacuum or negative pressure, the annular insertion groove  58   a  extends from a lower surface of the suction port  51 , and the balls  58   b  are inserted into the insertion groove  58   a.    
     While the suction port  51  of the embodiment has a structure including the annular insertion groove  58   a  and the plurality of balls  58   b  rotatably inserted into the groove  58   a , under the condition that the suction port  51  can move along the user&#39;s skin under the vacuum or negative pressure, the suction port  51  may have various end structures. 
     Meanwhile, the vacuum suction part  54  connected to the suction port  51  includes an one way valve  55  formed of a check valve, and so on, thereby maintaining the predetermined vacuum pressure in the suction port  51 . 
     In addition, when the air in the suction port  51  is sucked through the vacuum suction part  54 , a rhythm mode of repeatedly sucking the air in the suction port  51  at predetermined intervals, and a uniform mode of continuously maintaining the air sucked in the suction port  51 , may be operated. Preferably, the user may select the mode. 
     While the suction port  51  of the present embodiment has a semi-spherical shape, as long as the suction port  51  has a predetermined space for forming a vacuum pressure therein, and the vacuum pressure can be readily formed by the vacuum pump  57 , the suction port  51  may have various shapes such as hexahedron, oval, or the like. 
     In addition, the vacuum suction part  54  of the suction port  51  preferably has a circular or oval end periphery to be in close contact with the user&#39;s skin. 
     Hereinafter, a method or process of using a lipolysis device using a low power laser in accordance with an embodiment of the present invention will be described. 
     First, a doctor licensed to practice medicine at a medical institution brings the vacuum suction means  50  of the lipolysis device  1  using a low power laser into close contact with the user&#39;s skin where subcutaneous fat is to be broken down. That is, the suction port  51  of the vacuum suction means  50  is brought into close contact with an appropriate part of the user&#39;s skin such as the face, shoulders, armpits, and so on. 
     As described above, after the suction port  51  of the vacuum suction means  50  is brought into close contact with the user&#39;s skin, the vacuum pump  57  brings the interior of the suction port  51  to a predetermined vacuum pressure so that the skin covering the subcutaneous fat to be broken down is in close contact with an inner periphery of the suction port  51 . 
     After the skin covering the subcutaneous fat to be broken down is brought into close contact with an inner periphery of the suction port  51  to be positioned adjacent to the laser generating module  70 , the laser generating module  70  is driven to generate a laser through the laser diodes  72  and irradiate the skin with the laser. 
     That is, after attaching the suction port  51  of the vacuum suction means  50  to the user&#39;s skin in an area such as the face, shoulders, armpits and so on, the vacuum pump  57  sucks the air out of the suction port  51  to bring the skin into close contact with the inner surface of the suction port  51 , and the laser is radiated onto the skin to break down subcutaneous fat. 
     At this time, a low power laser with an output of 10 mW˜100 mW is generated through the respective laser diodes  72  of the laser generating unit  10 , and the generated laser passes through the transparent windows or lenses  73  to be radiated onto the skin, thereby breaking down subcutaneous fat. 
     Meanwhile, after the cover  76  is separated from the laser diode  72  of the laser generating module  70 , the male threaded part  74   a  and the female threaded part  75   a  formed at the upper and lower fixtures  74  and  75  are adjusted to adjust an interval between the laser diode  72  and the transparent window or lens  73 , preferably, at the beginning of the installation and treatment. 
     As described above, the subcutaneous fat is broken down by the laser radiated onto the user&#39;s skin suctioned by the vacuum suction means  50 , and the broken down subcutaneous fat is removed from the body by surgical operation. 
     In this process, since the subcutaneous fat broken down by the laser generated from the laser diodes  72  is located beneath the skin suctioned in the suction port  51  by means of the vacuum state in the suction port  51  of the vacuum suction means  50 , if the vacuumed suction port  51  is moved on the skin by means of rotation of the balls  58   b  inserted into the insertion groove  58   a  formed at the end of the suction port  51  in a scan manner, the broken down subcutaneous fat can be discharged through the groin, in which lymphatic vessels are abundant. 
     It is preferable to discharge the subcutaneous fat from the body after moving the subcutaneous fat broken down by the laser using the aforementioned method through the suction port  51  of the vacuum suction means  50 . 
     Meanwhile, manually opening or closing the manual negative pressure release hole  58  formed at the suction port  51  of the vacuum suction means  50  by the doctor or the user, the vacuum or negative pressure in the suction port  51  can be manually released, and therefore, the doctor or the user can readily set or release the vacuum or negative pressure formed in the suction port  51 . 
     When the vacuum suction means  50  is used on the user&#39;s head, blood circulation as well as hair growth can be promoted. 
     Meanwhile, as shown in  FIG. 12 , a relay may be installed at an appropriate place at a vacuum suction means having a laser generating module. Describing with reference to  FIGS. 10 and 11 , the relay  90  is installed at an appropriate place at the vacuum suction means  50  having the laser generating module  93 , and branches off into a plurality of connection vacuum line  91  having the vacuum suction ports  93 . In addition, the relay  90  is connected to the vacuum suction means  50  through the vacuum suction part  93 , and another vacuum line  91  connected to another vacuum suction part  93  having the laser generating module  70  is connected to another vacuum suction part  93  of the vacuum suction means  50  having another laser generating module  70 . 
     As described above, a plurality of vacuum suction means  50  each having laser generating module  70  are connected to the relay  90  through the connection vacuum lines  91  so that the vacuum suction means  50  can be in contact with a predetermined area of skin where subcutaneous fat is to be broken down. 
     In this process, the connection vacuum line  91  for connecting the vacuum suction means  50  having the laser generating module  70  and the relay  90  through the vacuum suction part  93  has a length that may be variably adjusted by the user, thereby enabling many people to use the lipolysis device. 
     For this purpose, any one of the connection lines  91  branching off from the relay  90  may be connected to the vacuum pump  95  for forming a predetermined vacuum pressure in the suction port  51 , and another connection vacuum line  91  may be another relay  90 . 
     As described above, the relay  90  for connecting the plurality of vacuum suction means  50  having the laser generating modules  70  may be connected to another relay  90 ′ through the connection vacuum line  91  so that the plurality of vacuum suction means  50  are in contact with the user&#39;s skin. 
     Although the present invention has been described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that a variety of modifications may be made therein without departing from the spirit or scope of the present invention defined by the appended claims and their equivalents.
