An opening 214b for external emission of the laser L may be formed in a substantially central region of the front portion 214a. The opening portion 214b may be sealed by the transparent portion 270. FIG.

The reflector 250 may be provided so as to achieve uniform emission through efficient reflection of the laser L. The reflector 250 may be made of a material having a high reflectivity such as aluminum. The reflective portion 250 may be provided with a path 252 for moving the laser L. [ The laser L incident on the handpiece body 110 may be moved along the laser movement path 252 and may be emitted to the treated part of the subject. The inner wall of the laser movement passage 252 may have a reflecting surface 254 formed to be inclined so that the passage width increases toward the opening 214b. More specifically, the reflecting surface 254 may be formed to be inclined so that the cross-sectional area of the laser movement path 252 increases from the entrance to the exit of the laser movement path 252 (i.e., the opening 214b) have. Accordingly, the laser movement path 252 may have a conical, quadrangular, or polygonal cross section.

The laser L incident on the entrance of the laser movement path 252 is reflected by the reflection surface 254 and is uniformly injected through the opening 214b, And diffusion can be made and released.

The diffusion unit 260 is disposed at an upper portion of the inner space 211 of the handpiece body 210 to primarily diffuse the laser L incident on the handpiece body 210, (250). More specifically, the diffusion portion 260 may be disposed on the upper laser incident region of the reflective portion 250. The diffuser 260 may be composed of a plurality of lenses, and the lens closest to the reflector 250 among the lenses may function as a diffusion plate (not shown). Through the diffusion portion 260, the incident laser beam L is refracted and the laser irradiation range can be primarily diffused. The laser light L that has been subjected to the primary diffusion process may be subjected to a secondary diffusion process while reaching the reflection unit 250 and may finally be uniformly irradiated onto the treatment site through the light projecting unit 270 .

The light projecting unit 270 can irradiate the laser light L subjected to the second diffusion treatment to the treatment site while minimizing the light transmission loss. For this, the transparent portion 270 may be provided as a light transmissive plate that is provided to cover the opening 214b and is made of a material that minimizes light transmission loss.

As another example, the transparent portion 270 may include a transparent plate made of a transparent oxide electrode.

The laser handpiece 200 having the above-described structure can generate heat at a high temperature during the procedure. Such a heat can be generated in the laser handpiece 200 by a large amount of heat generated in the inner space directly irradiating the laser light L to the treatment area, particularly in the reflective area 250. Such a heat greatly affects the lifetime and the reliability of the product. However, since it acts as a factor that greatly increases the risk of burn in the treatment area of the patient, a cooling system that exhibits highly efficient cooling efficiency due to the characteristics of a medical device requiring high operator safety characteristics It is essential.

The handpiece cooling unit 500 according to the embodiment of the present invention may be provided for preventing overheat of the handpiece 200 and preventing the burn of the operator to achieve the above object. The handpiece cooling unit 500 includes a first cooling unit 510 and a second cooling unit 520. The first cooling unit 510 is a water cooling type cooling system using a cooling fluid And the second cooling unit 520 may be a cooling system employing a non-water-cooled cooling system.

The first cooling unit 510 may include a cooling fluid storage container 512 and a cooling fluid circulation line 514.

In this case, the cooling electrode 522 can directly cool not only the cooling of the transparent portion 270, but also the treatment portion that is contacted during the operation.

On the other hand, it is preferable that the cooling electrode 522 is made of a material having high light transmittance. More specifically, the cooling electrode 522 is a thin conductive film formed on the transmission path of the laser L, and may be located on the transmission path of the laser L. Therefore, when the light transmittance of the cooling electrode 522 is low, the light loss of the laser L during the light transmission of the transparent portion 270 may increase, or scattering and interference may occur. Accordingly, it is preferable that the cooling electrode 522 is made of a material capable of uniformly cooling the entire light transmitting portion 270 while minimizing a decrease in light transmittance of the laser L. As an example, the cooling electrode 522 may be an indium tin oxide (ITO) film. When the cooling electrode 522 is an ITO film, the cooling electrode 522 may be formed as a thin film through a thin film deposition process (cf. sputtering process, etc.) on the transparent portion 270.

For the automatic control of the cooling system described above, the first and second cooling units 510 and 520 may be equipped with various valves, sensors, and flow meters, and these electronic devices may be controlled by the control unit 150 The laser handpiece 200 can be maintained in a predetermined temperature range. The controller 150 may control the laser handpiece 200 to maintain a predetermined temperature by comparing the temperature sensed data received from the temperature sensor 244 with a preset temperature range.

In addition, the second cooling unit 520 may be a non-water-cooled cooling system, and may further include a separate cooling unit. For example, the second cooling unit 520 may include at least one thermoelectric element (not shown) disposed adjacent to the sidewall of the inner space of the handpiece body 210 or adjacent to the reflection unit 250 and in contact with the cooling electrode 522, (Or Peltier element). In this case, the cooling power source 524 may apply a current to the thermoelectric element to provide cool air to the cooling electrode 522.

Particularly, since the transparent portion 270, which is a central region of the front surface portion 214a, can be directly cooled while minimizing the light transmission loss, even in the region where the laser L is directly irradiated to the treatment region during the fat reduction procedure It can be provided that effective cooling is achieved. Accordingly, the laser handpiece 200 according to the present invention and the fat reduction device 10 having the laser handpiece 200 according to the present invention can be used as a laser handpiece 200 using a high power laser for laser fat reduction and a handpiece cooling unit Wherein the handpiece cooling unit 500 includes an outer area of the front part 214a facing the treatment area of the handpiece body 210 as well as an outer area of the front part 214a, The light emitted from the laser handpiece 210 can be effectively cooled by minimizing the risk of burns of the subject during the procedure, The reliability and the safety of the operation can be improved.

Meanwhile, although the cooling electrode 522 is provided in a predetermined pattern shape in the embodiment of the present invention, the shape, structure, shape, and forming angle of the cooling electrode 522 may be variously applied .

As another example, as shown in FIG. 6 (b), the cooling electrode 522 may be formed in a pattern having a comb pattern (or an unmatched comb pattern) crossing each other. As another example, the cooling electrode 522 may be formed as a thin film covering the entire surface of the transparent plate of the transparent portion 270, as shown in FIG. 6 (c).
