ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laser treatment device for dermatology using a laser. More specifically, the present invention relates to a laser treatment device for dermatology that removes so-called colored birthmarks, such as abnormal blood vessel clusters and punctate pigment spots.

急速に治瘉する。 Pigmented abnormal cells, such as red birthmarks, are generally less bright than normal cells, and absorb visible light more strongly than normal cells, which are brighter. Therefore, when these abnormal cells are irradiated with a high-energy laser beam in the visible light range, the beam is selectively absorbed by the abnormal cells and converted into thermal energy. As a result, abnormal cells are strongly burned and destroyed. On the other hand, normal cells generally have high brightness and therefore absorb little of the laser beam. Therefore, there is little damage to normal cells due to heat. Therefore, when irradiating telangiectasia disease with such a laser beam, abnormal cells are selectively burned and blood does not flow, so red bruises disappear, but normal cells with relatively high brightness, sweat lines, Since the skin hardly absorbs the laser beam, irreversible damage is avoided, and burns on normal cells and skin surfaces caused by the laser beam heal quickly with the formation of minute scars.

率良く治療を行なうことは困難である。 As a conventional therapeutic argon laser device for dermatology, there is a device designed by Coherent Inc. of the United States. This device uses a mechanical shutter to generate pulses from a power device that houses a power source and a laser oscillation tube in one piece, and guides the pulses through an optical glass fiber as a light guide path to a laser gun attached to the tip of the fiber. The gun is configured so that the light is focused to about 1 mm by a lens provided on the gun and irradiated onto the affected area. With this device, during treatment, the practitioner holds a laser gun in his hand, sequentially moves the irradiation position 1 mm at a time while checking the affected area with the naked eye, and uses a foot switch to irradiate the laser to perform treatment. However, it is quite difficult to arrange the 1 mm irradiation circles uniformly while checking with the naked eye, or to keep the irradiation time of each beam constant. As a result, if the arrangement of the irradiation circles becomes disordered and their overlapping becomes severe, damage to abnormal cells becomes significant and scarring remains.
On the other hand, if the interval between the irradiation circles is too wide, that portion will remain as an untreated portion without being erased. Furthermore, if a constant irradiation time cannot be maintained, burn spots are likely to occur, and damage to the skin surface cannot be avoided, especially if the irradiation time is long. Therefore, with conventional equipment that performs laser irradiation while checking with the naked eye, there is a lot of time loss and the practitioner is extremely fatigued, making it difficult to perform treatment efficiently.

囲の組織をも破壊する恐れがあり好ましくない。 In addition, argon lasers have a lower output than high-output ruby lasers that can rapidly apply high energy in a short period of time (for example, 0.001 seconds), so it takes a long time to irradiate the same amount of energy as above. Irradiation must be carried out. However, when a low-energy laser is irradiated to the affected area for a long time, the amount of energy that contributes to raising the temperature of abnormal cells out of the total irradiated energy will indiscriminately affect surrounding tissues that do not need to be treated due to heat conduction. The amount of energy for heating increases. Therefore, in order to provide effective treatment, irradiation has to be carried out for a longer period of time. However, long-term irradiation is not preferable because it may also destroy surrounding tissue.

This can easily lead to difficulties in carrying out the procedures.

レーザ治療装置である。 The present inventors have arrived at the present invention as a result of intensive studies aimed at providing an improved device that can effectively perform treatment without reducing the efficiency of the laser treatment device. That is, the present invention provides a laser treatment device for dermatology in which a laser oscillated by a laser oscillator is guided to a laser gun attached to the tip of a glass fiber, and a laser beam is irradiated to the affected area from the tip of the laser gun. A vertical and horizontal moving table is attached to a support table having a vertical movement mechanism, and a laser gun and a sterilized liquid and/or gas are supplied to the laser irradiated area to a bracket attached to the moving table. The affected area cooling mechanisms are mounted adjacent to each other, and the control device is configured to move the laser gun mounted on the moving table and appropriately irradiate the laser gun to the affected area cooled by the affected area cooling mechanism. This is a laser treatment device for dermatology.

である。 The novel idea of the present invention is that the laser gun is fixed to a vertically and horizontally movable table, and the movable table can be moved as appropriate by a control device. Based on this idea, it has become possible to uniformly arrange the irradiation circles on the affected area, and the irradiation time to the affected area is constant, making it possible to perform effective treatment without burning spots.

FIG. 1 is a diagram illustrating the configuration of the device of the present invention, which includes an argon laser oscillation device 1, an optical glass fiber 2 for guiding laser light, a laser gun 3 attached to the tip of the glass fiber, Vertical and horizontal moving table (hereinafter referred to as X-) equipped with a laser gun
It is composed of a Y table (referred to as Y table) 4, a support table 5 on which the moving table is mounted, and a control device 6 for operating the XY table and laser irradiation. 7
is a remote control switch for remotely controlling the control station. The support stand 5 preferably includes the cart 1
It consists of a vertical shaft 11 fixed at 0, and a horizontal member 12 that moves up and down along the shaft and moves in the horizontal direction. Both horizontal members can be moved by means of a rack mechanism. An X-Y table is attached to one end of the horizontal member, and a weight 8 for maintaining balance is attached to the other end. X
- The Y table 4 has a base 20 as shown in FIG.
A Y-table 21 is movably mounted on this base, a base 22 is fixed on this Y-table, and an X-table 2 is movably provided on this base in a direction orthogonal to the Y-table.
It consists of 3. The X and Y tables are each directly connected to a worm reducer 24 with a step motor and screwed onto a rotating threaded rod 25, and are configured to move forward and backward as appropriate by rotation of the threaded rod. In order to move the table stably, at least one guide member 26 is preferably fitted into the table parallel to the threaded rod at a distance. The X and Y tables have exactly the same shape. The X-Y table may have various known structures in addition to the above structure. A bracket 30 for fixing the Regan is attached to the X table. A hollow circular member 27 is fixed to the tip of the bracket, and a laser gun is attached to this member. Limit switches 28 are attached to both ends of the base on which each table is installed, to regulate the movement range of the table, and for hygiene reasons.
- It is preferable to cover the entire Y table to prevent lubricating oil etc. from falling. Figure 3 is X-Y
3 is a diagram showing the relationship between a patient and a laser gun 3 attached to a hollow circular member 27 provided at the tip of a bracket 30 attached to a table 4. FIG. An affected area cooling mechanism, for example, a liquid sprayer 3, is adjacent to the laser gun 3 and cools the contact point between the laser beam and the living tissue.
1 is attached to the above bracket. 32
is bet, and 33 indicates the patient. Although various structures can be adopted for the liquid sprayer, FIG. 3 shows a liquid sprayer using a jet pump. Such a sprayer is compact and has small droplets, so it has a large cooling effect and is preferable. As shown in Fig. 4, which shows the cross-sectional structure of a liquid sprayer using a jet pump, the sprayer has a gas inlet 40 and a liquid inlet 41, and the liquid flows out at high speed through a nozzle formed in the sprayer. It is sucked in by the reduced pressure effect when The gas that has sucked the liquid collides at high speed with a resonance plate 43 supported by a plurality of support members at the tip of the fluid discharge port 42 to generate ultrasonic waves and form very small droplets. Liquid spraying has a cooling effect, but there is a risk that the liquid droplets will scatter to the surroundings, and it is necessary to prevent such droplets from scattering. In addition to the liquid spray described above, a liquid or gas may be continuously supplied to the contact point between the laser beam and the living tissue. However, although the former has a great cooling effect, there is a risk that the supplied liquid may contaminate the surroundings. Further, the latter must be a low-temperature gas in order to obtain a cooling effect, and therefore it is necessary to provide a separate gas cooling means. Therefore, it is preferable that the affected area cooling mechanism adopts an optimal method as required. It goes without saying that the liquid and/or gas for cooling the affected area must be sterilized. Furthermore, it must not be harmful to living organisms.
Preferably, water, physiological saline, Hibitene (trade name), etc. can be used as the liquid, and air, nitrogen gas, carbon dioxide gas, (saturated) water vapor, etc. can be used as the gas. Among these, physiological saline, nitrogen gas, or carbon dioxide gas is particularly preferred. A suction mechanism 50 is provided in the vicinity of the point of contact between the affected area and the laser beam to suction and remove products such as toxic gas due to protein decomposition due to the interaction between the laser and the living body. This mechanism is composed of a flexible tube 51 connected to a pipe connected to a vacuum pump, and a suction nozzle 52 provided at the tip of the tube. Preferably, the flexible tube has appropriate rigidity so that it can be moved and fixed to the affected area as appropriate. On the other hand, it is preferable that the nozzle has an enlarged tip.

照射を行つてもよい。 Next, an example of the operation of the apparatus of the present invention will be explained with reference to FIG. First, adjust the horizontal member that makes up the support base, position the X-Y table attached to one end of the horizontal member near the patient's affected area to be treated, and further increase the distance between the tip of the laser gun and the affected area by 16 ~
46 mm, and then adjust the X-Y table using the control device to determine an arbitrary position of the affected area 60 as the zero point. When the zero point is determined, 1 in the X direction from the point
Move the laser gun using a remote switch while checking the affected area mm by mm. Once the gun has finished moving, the laser irradiation switch is automatically turned on and pulses of the laser are irradiated to the predetermined position. This operation is performed continuously, and when the laser irradiation in the X direction within the preset range is completed, the laser gun automatically returns to the zero point, and then automatically moves 1 mm in the Y direction. , similarly to the above, the gun is automatically moved in the X direction and the laser is irradiated. The method of moving the laser gun is not limited to the method described above, and can be selected as appropriate. Further, continuous laser irradiation may be performed while the laser gun is automatically traveling.

うまでもない。 In addition, to observe the laser irradiation on the affected area,
Alternatively, the device can be equipped with a television system in order to perform laser treatment remotely. The television camera is hinged to an X-Y table and directed to the irradiation position. Images taken by the television camera are displayed on a monitor provided in the control device. Therefore, the zero point can be appropriately set at the affected area imaged on the monitor, and treatment can be performed while observing the irradiation position on the monitor. Such a system is preferable because it ensures the safety of the practitioner from leakage radiation from the laser oscillation device. It goes without saying that treatment can be performed automatically by connecting the monitor and the control device.
