Description

[0001] The present invention relates to a laser treatment apparatus with an auto-adjustable focal distance,

 The present invention relates to a medical laser treatment apparatus capable of adjusting focus in real time, and more particularly, to a medical laser treatment apparatus capable of adjusting a focus in real time, and more particularly, The present invention relates to a medical laser treatment apparatus capable of focusing in real time and capable of irradiating with a focal distance corresponding thereto according to a point to be irradiated.

Today, various laser treatment techniques for irradiating and irradiating a laser beam to the skin for the purpose of treatment and the like are being developed, and a medical laser device for using a laser treatment technique is actively studied.

The laser treatment technique is used for various purposes such as skin peeling, skin regeneration, whitening, wrinkle or spot removal, stain removal, and there are differences in devices and techniques depending on the purpose of use, except that a laser is used. There are differences in the conditions for irradiating the laser beam and the apparatus used.

On the other hand, in the case of a conventional medical laser apparatus having a scanner function, a desired therapeutic effect is obtained by sequentially irradiating a laser beam over a predetermined irradiated surface. At this time, the laser beam irradiates the irradiated surface while moving relative to the irradiated surface.

In this case, since the conventional laser apparatus irradiates the irradiated surface with a laser beam having a constant focal distance, the following problems arise.

1, which conceptually represents a part of the configuration of a conventional apparatus, a laser beam 100 is irradiated onto a point P1 104 of the irradiated surface 103 via a focus lens 101 having a focal length L do. Since the point P1 104 is positioned in accordance with the focal length L of the focus lens 101, that is, at the initial point, the spot of the laser beam 100 irradiated on the point P1 104 is pre- It becomes a spot having an intended size.

However, in the conventional apparatus having the XY scanner for moving the irradiated position of the laser beam on the irradiated surface 103, when the irradiated point moves to the point P2 105, The size of the spot of the laser beam irradiated on the point P2 105 of the laser beam spot becomes larger because it is away from the background point. Also, the spot size of the laser beam irradiated at a point closer to the center point distance becomes larger.

2 conceptually shows a change in the size of a spot irradiated with a laser beam when a laser beam is irradiated onto a predetermined irradiated surface 112 in the case of a conventional apparatus having a conventional scanner function.

Assuming that the spot size of the point P3 113 at the position corresponding to the initial point is intended in advance, the spot size of the points 114 and 115 located apart from the point P3 113 becomes larger. This is because the point to be irradiated is changed in the state where the focal distance is constant and deviated from the shedding point.

The case where the irradiated surface is a curved surface is illustrated in Fig. The size of the spot when the laser beam having a certain focal distance is irradiated on the irradiated surface 120 of the skin having the curvature is smaller than the size of the spot at the point 122 corresponding to the shedding point And becomes larger at the further distant point 123.

As described above, regardless of the type of laser used and the type of oscillation, in the case of all conventional laser beam therapy apparatus equipped with a scanner, the size of the spot of the laser beam irradiated at the position corresponding to the focal length is The larger the size of the intended spot is. The size of the spot becomes larger than intended when the laser beam is irradiated to a point located far away from the focal point or to a spot located close to the focal point.

If the spot of the ray spot beam is larger than intended, the irradiated area becomes larger than the intended area, resulting in excessive skin damage, resulting in a delayed recovery, scarring or various side effects.

The joint part 40 serves to change the path of the laser beam in a desired direction and allows the operator to move the laser beam irradiating part 50 to a desired point on the skin of the client. One end of the joint part 40 is coupled to the laser oscillating part 10 and the other end is coupled to the laser beam irradiating part 50. 4, two reflection mirrors 42 and 44 are illustrated, but it is also possible to increase the reflection mirrors 42 and 44 according to the number of joints.

The laser beam irradiating unit 50 is configured such that the laser beam 2 that has passed through the joint 40 is irradiated over a predetermined irradiated surface. The laser beam irradiating unit is usually provided in a structure called a handpiece 210, which is normally used by a practitioner in a hand.

In the case of this embodiment, the wavelengths of the laser beams emitted from the laser beam 2 and the laser oscillation portion for distance measurement are 1064 nm and 650 nm, respectively.

The distance measuring sensor 92 detects a laser beam reflected from the irradiated point after being oscillated in the distance measuring laser oscillating unit 91 and returning. The sensed data is transmitted to the main control unit, and the main control unit calculates the distance value from the focus lens 58 of the laser beam irradiating unit to the irradiated point based on the data.

The first beam splitter 93 is provided on the path of the laser beam. The first beam splitter 93 selectively transmits or reflects the light beam according to the wavelength of the light beam. The first beam splitter 93 is provided between the concave lens 53 and the first mirror 54 to allow the laser beam to pass therethrough and to reflect the laser beam for measurement generated in the distance measuring laser oscillating unit 91.

The distance measuring laser beam emitted from the distance measuring laser oscillating section 91 is reflected by the first beam splitter 93, the first mirror 54 and the second mirror 56 and then passes through the focus lens 58 The reflected and reflected distance measuring laser beam is irradiated to the irradiated point and passes through the second mirror 56 and the first mirror 54 through the focus lens 58, And a path reflected by the first beam splitter 93, and is incident on the distance measuring sensor 92.

The DFE includes a liquid crystal lens (not shown) whose curvature is controlled according to the applied pressure. That is, the laser beam incident through the joints is irradiated to the irradiated surface after sequentially passing through the liquid crystal lens and the focus lens. When the pressure applied to the liquid crystal lens is adjusted, the curvature is adjusted Accordingly, the focal length of the laser beam can be adjusted and examined.

The liquid crystal lens is a lens whose thickness is thickened when the pressure is applied to the rim of the lens, and when the applied pressure is weakened, the convex portion of the center portion is inserted and the thickness is thinned.

At the same time, the focal distance at each irradiation point is determined by the moving module 52 . At this time, the focal distance of the laser beam 2 is adjusted in real time so as to correspond to the real-time distance from the laser irradiation part to the irradiated point measured by the real-time distance measurement module 90.

The laser beam may be irradiated while being moved by the X-Y scanner, and the movement may be repeated when the laser beam is once moved and then irradiated in the stationary state and again stopped irradiation. At any moment, the distance to the irradiated point is measured, and the moving module 52 is operated according to this value to control the focal distance. In accordance with the overall control of the main controller 20, Lt; RTI ID = 0.0 > constantly < / RTI >

5 and 6, the size of the spot of the laser beam 2 irradiated on each of the points 121, 122 and 123 of the surface to be irradiated 120, which is a curved surface, is constant.

7 and 8, the practitioner holds the handpiece 210 provided with the laser beam irradiating section 50 in hand and puts the end of the gap maintaining means 60 at a specific point on the irradiated surface 120 As long as it exists, the laser beam is irradiated to the whole point over the predetermined irradiated surface. In the case where the interval maintaining means is a cylindrical shape with an open end, a part of the internal area of the end rim becomes a pre-determined irradiated surface.

In the present embodiment, the camera module 95, the second beam splitter 98, and the display unit 80 are further provided.

The camera module 95 includes a CCD camera 96 and a zoom lens 97.

The CCD camera 96 is one of digital cameras and converts an image into an electric signal by using a charge coupled device (CCD) to store it as digital data in a storage medium such as a flash memory.

Hereinafter, the operation and effect of the medical laser therapy apparatus 1 capable of focusing in real time in one embodiment of the present invention will be described.

According to the medical laser treatment apparatus 1 capable of adjusting the focus in real time in the embodiment, the focal distance is automatically adjusted according to the distance to the irradiated point measured in real time, whereby the size of the spot of the laser beam to be irradiated There is an advantage in that it can always be kept constant at a desired size throughout the entire range.

This is advantageous in that even if the point at which the laser beam is irradiated is moved, the distance to the irradiated point is measured in real time, and based on the measured value, the control unit adjusts the focal distance of the laser beam, The present invention is not limited thereto. The focal length is adjusted by moving the concave lens by the moving module 52 under the control of the main control unit 20. When the practitioner touches the skin of the patient with the handpiece and presses the laser beam switch, the laser beam is not immediately irradiated, but the distance to the irradiated point is first measured by the real-time distance measuring module, After the focal length is adjusted, the laser beam is irradiated. Since this series of procedures is performed in an extremely short time, there is no time difference experienced by the practitioner. That is, when the laser beam switch is pressed, the laser beam is directly irradiated.

Since the spot size of the laser beam can be kept constant over the surface to be irradiated, it is possible to perform the treatment only with the optimum spot size only in the portion requiring treatment, resulting in quick recovery and minimization of side effects and scarring .

According to the medical treatment apparatus of the present invention, the skin of the human body, which is the surface to be irradiated, has various shapes, so that it is often performed with a spot size larger than the intended size. However, By adopting a regulated configuration, it becomes possible to always operate with the optimum spot size. That is, the distance between the laser beam irradiating part and the irradiated point is measured in real time during the procedure and based on this value, the focal distance of the laser beam is also adjusted in real time.

On the other hand, in the case of the present embodiment, since the configuration of the camera module 95 is included, there is an advantage that the practitioner can perform the operation while monitoring the irradiated point. There is a skin condition that can be treated or treated with a laser beam for skin treatment, and there is a skin condition that can not be done. Referring to FIG. 10, in which photographs provided by the Korean Society of Skin Medicine are attached, FIG. 1 shows a photograph of a pigment, FIG. 2 shows a malignant melanoma, and FIG. 3 shows a daylight surplus. 4 shows photosynthetic basal cell carcinoma, 5 shows pigmentary basal cell carcinoma, and 6 shows malignant melanoma.

Of these, one or three times the skin condition can be treated with laser, but the remaining condition is that the laser treatment should not be done. The skin condition is usually checked by a practitioner before the laser procedure. However, it is possible to grasp the skin condition in real time during the procedure, thereby preventing the danger that may occur and also enabling an appropriate treatment.

Although the present invention has been described with reference to the embodiments shown in the drawings, it is to be understood that various changes and modifications may be made without departing from the scope of the present invention. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
