Description

TECHNICAL FIELD [0001] The present invention relates to a laser system for treating body tissues,

The present invention relates to a laser system for treatment of body tissue, and more particularly, to a laser system for treating a body tissue, and more particularly, to a laser system for treating body tissue, And more particularly, to a laser system for treatment of body tissue.

Generally, the temperature can be raised or lowered in selected areas of tissue for various therapeutic and cosmetic purposes.

Various forms of electromagnetic radiation, including for example heated pads or plates or microwave radiation, electricity, infrared and ultrasound have been used to heat subcutaneous muscles, ligaments, bones, etc., such as increasing blood flow.

It can promote healing of various injuries and other injuries and can be used for bronchial or hyperthermia treatment, poor blood circulation therapy, physical therapy, collagen stimulation, cellulite treatment, adrenaline stimulation, wound treatment, psoriasis treatment, body reshaping and non invasive wrinkle removal. Do. The heating can be applied to a small local area, a large area, for example a larger tissue area including the hands or feet, or the entire body.

In addition, although optical and near infrared (NIR) and radiation (collectively referred to as " optical radiation ") are generally less expensive and less mutable than microwave radiation, the use of optical radiation has, until now, Tissue, some of which may be located mainly below the dermis, the depth of which is largely greater than 1 mm, and the tissue beneath this border extends up to a depth of up to about 50 mm.

The reason that optical radiation is not considered appropriate is that such radiation is highly dispersed and highly absorbed at the surface layer of tissue, and a significant portion of such radiation reaches the tissue region and does not cause heating.

From the point of view of energy loss due to scattering and absorption, substantial optical (including near-infrared) energy must be applied so that sufficient energy is supplied to reach the tissue region of depth in order to obtain the desired effect.

However, this high energy can damage the surface layer of the tissue, making it difficult to achieve the desired photothermal therapy in the tissue area.

For this reason, optical radiation has limited value for therapeutic and cosmetic treatment in deep tissue.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

Here, the attached drawings are exaggerated or simplified in order to facilitate understanding and clarification of the structure and operation of the technology, and the components do not exactly coincide with actual sizes.

FIG. 6 is an enlarged view of a lens portion. FIG. 6 is a front view showing the operation of an 'applicator' of a laser system for treatment of a body tissue.

As shown in Fig. 1, the laser system for treatment of the body tissues includes:

A cable 120 connected to the body 120 and an applicator A formed on an end of the cable 120 for generating a laser and contacting the skin, will be.

The applicator A, as shown in Figs. 2 to 6,

A light generating part (2) having a lamp (22) connected to a cable (120) at one side and generating laser light;

A lens unit 4 for diffusing laser light generated in the light generating unit 2;

A reflection member (6) formed inside the housing, for reflecting the laser light having passed through the lens unit (4) and concentrating the laser light to a specific position;

And a facing surface irradiating unit 8 having a plurality of glass plates 81 and 82 for allowing the laser light concentrated by the reflecting member 6 to pass therethrough and contacting the skin.

Here, the lamp 22 and the facing portion 8 are formed in a rectangular shape, and the lamp 22 is formed in a direction perpendicular to the facing portion 8 (see an enlarged view of FIG. 3).

By configuring the facing surface irradiating section 8 in the direction perpendicular to the lamp 22, it becomes possible to further diffuse the laser horizontally.

That is, the horizontal and vertical sizes of the glass plates (the surfaces to which the laser is irradiated) 81 and 82 of the facing portion 8 of the applicator are long by 6X4.

Since the lamp 22 is arranged in the direction perpendicular to the long side of the glass plates 81 and 82 so that the degree of diffusion of the lamp 22 in the left and right directions is low and the laser is diffused up and down in the direction of the optical axis of the lamp 22, In order to minimize the loss, the facing surface irradiating portion 8 is formed in a direction perpendicular to the lamp 22 so as to accommodate the spreading range of the laser, thereby allowing the laser to uniformly disperse in the long facing surface irradiating portion 6X4 .

The light generating part 2 includes a lamp 22, that is, a laser diode and a diffuser housing 24 surrounding the lamp 22.

And a water base 26 formed to contact the lamp 22 and the diffuser housing 24 and storing the cooling water.

The water base 26 stores cooling water therein to cool and overheat the lamp 22 and the diffuser housing 24 due to heat generation.

The lens unit 4 is accommodated in the diffuser housing 24 of the light generating unit 2, and a plurality of concave lenses are spaced apart from each other by a predetermined distance.

It is preferable that the lens unit 4 is formed by a first lens 41 and a second lens 42 with two concave lenses spaced apart from each other by a predetermined distance and is formed in the lamp 22 of the light generating unit 2 Thereby effectively diffusing the light source.

The concave lens basically has a light diffusing effect. The present invention aims at spreading a laser with a narrow diffusing angle at a shortest possible distance.

Therefore, the diffusion range can be increased so that laser energy can be widely spread by forming concave both surfaces of the first lens 41 and the second lens 42.

In addition, the dual structure of the first lens 41 and the second lens 42 makes it possible to maximally diffuse at a short distance.

According to the embodiment, the first lens 41 is formed of a first curved surface 411 facing the lamp 22 and a second curved surface 412 facing the first curved surface 411. The curvature radius of the first curved surface 411 is smaller than the curvature radius of the second curved surface 412 so that a lens having a large radius of curvature Thereby efficiently diffusing the light source. The laser heat can be uniformed.

According to one embodiment, the thickness of the first lens 41 and the second lens 42 is thicker than that of the first lens 41 and the second lens 42.

A lens having a large thickness and a second lens 42 are disposed in front of a reference point in the laser diffusion direction to efficiently diffuse the light source. The laser heat can be uniformed.

Further, a clear aperture (lens effective radius) of the lens is formed so that the first lens 41 is smaller than the second lens 42 (the first lens <the second lens).

 The second lens 42 having a large radius is disposed at the front end relative to the direction of the laser diffusing direction so that the laser beam passing through the first lens 41 is diffused or curved without passing through the second lens 42, The heat can be uniformed.

6, the radius of the first curved surface 411 of the first lens 41 is larger than the radius of the second curved surface 412 of the first lens 41, the third curved surface 412 of the second lens 42, The second curved surface 423 of the second lens 42, and the fourth curved surface 424 of the second lens 42. [

 The second lens 42 having a large radius is disposed at the front side relative to the laser diffusion direction to efficiently diffuse the light source. The laser heat can be uniformed.

Table 1 below summarizes one embodiment of the radii and thicknesses of the first lens 41 and the second lens 42.

The first lens The second lens The first curved surface The second curved surface The third curved surface 4th surface Radius -10 20 -20 60 thickness 2 5

On the other hand, the reflective member 6 is formed so that the both ends thereof are opened and the inner surface of the reflective member 6 is expanded from one end to the other end. In other words, in the incident portion corresponding to the lens portion 4, the inner surface is expanded toward the exit port corresponding to the facing surface irradiating portion 8, and is formed into a funnel shape.

A reflecting surface is formed so that light can be reflected on the inner circumferential surface of the reflecting member (6).

Light diffused by the lens unit 4 and spread widely can be reflected toward the center while being reflected by the reflecting member 6, so that light energy loss can be prevented.

The front-rear length L2 of the reflecting member 6 is formed to be 0.8 to 1.5 times the length L1 of the long side of the emitting port, and is preferably formed to be one time.

An energy loss is generated while the light emitted from the lens unit 4 passes through the reflection member 6. If the length is 0.8 to 1.5 times as long as described above, in the exit surface of the reflection member 6, So that the intensity of the laser light entering into the optical system is not damaged by the skin.

When the length L2 of the reflective member 6 is less than 0.8 times the length L1 of the long side of the exit port, the light is not sufficiently diffused and the laser is irradiated unevenly on the treated region. Therefore, If the length of the front and back of the reflecting member exceeds 1.5 times the length of the long side of the emitting orifice, the wavelength of the laser can not be sufficiently irradiated to the treatment site, and the effect of the treatment becomes poor.

On the other hand, when the front-rear length L2 of the reflecting member 6 is one time longer than the long-side length L1 of the emitting orifice, the light energy loss is minimized and the energy is uniformly irradiated to the treatment site.

The facing surface irradiating unit 8 includes a housing 84 having a receiving space formed therein and having openings on both sides thereof; And a gasket 86 housed in the housing 84 and coupled between the upper and lower glass plates 81 and 82 and between the upper and lower glass plates 81 and 82. Cooling water is supplied into the gasket 86 And a gasket 86 is formed with a water inlet for injecting cooling water and a water outlet for discharging cooling water.

The size of the actual glass plate to which the laser is irradiated is composed of a ratio of 4: 6 in width and length, which means that the laser irradiated from the lamp 22 is uniform To the body tissue of the patient.

On the other hand, a plurality of suction holes 85 may be formed on the front surface of the housing 84 of the facing portion 8. A negative pressure may be generated through the suction hole 85 so that the lower glass plate 82 is brought into close contact with the treatment site to irradiate the laser. That is, when a negative pressure is generated through the suction hole 85, the treatment site in close contact with the gasket 86 is cooled, and the treatment site closely attached to the glass plate 82 is irradiated with the laser in the close contact state. As a specific example, a vacuum inhaler (not shown) may be used. The vacuum inhaler is configured to communicate with a vacuum suction means (not shown) and a suction hole 85.

The gasket 86 is formed of an aluminum material having a high thermal conductivity and is formed to have a predetermined thickness. The upper and lower glass plates 81 and 82 are coupled to both sides of the gasket 86, and an O-ring 863 is interposed therebetween, The lower glass plates 81 and 82 are coupled.

Accordingly, the cooling water is injected through the inlet port 87 and the cooling water can be filled in the gasket 86, that is, between the upper and lower glass plates 81 and 82, and the cooling water heated through the outlet port 88 is continuously discharged The inside of the gasket 86 always has cool cooling water, so that the skin that is in close contact with the housing 24 and the lower glass plates 81 and 82 can be protected from burns.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments or constructions. Various changes and substitutions may be made without departing from the spirit and scope of the invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
