Laser Procedure System using Skin thickness, Color distinction and Image recognizing Device}

The present invention relates to a laser treatment system using skin thickness, color discrimination, and image recognition device. More specifically, the thickness, color, etc., of the skin at the laser treatment site are automatically recognized by a camera, an ultrasonic sensor, and the like. The present invention relates to a laser treatment system using skin thickness, color discrimination, and image recognition apparatus that can automatically adjust the intensity of a laser through an operation server in which algorithm programs such as depth, image recognition, and color discrimination, such as depth, should be performed.

In general, LASER stands for "Light Amplified by Stimulated Emission of Radiation." The principle of operation of a laser, as the name implies, is "amplification of light by induced emission of radiation." In a laser machine, one light particle induces the emission of the same other particle in an excited medium.

The light particles are reflected by a mirror installed in the machine and again pass through the medium and induce the release of other light particles. There are two mirrors in the machine, the mirrors on the front are semi-permeable and allow some light to pass through. The light thus obtained is a parallel light beam that is bright, short-wavelength, temporarily or spatially cohesive, and does not diffuse, but is conducted in parallel, which is a laser beam.

In other words, the electrons in a orbit are pulled up to a high energy level by applying external energy, and then returned to their original position, and the energy difference generated by the light is collected into one direction by using a special device to have a strong energy. Amplification device.

Such lasers can be classified into solid lasers (ruby lasers, alexandrite lasers, etc.), liquid lasers (color lasers), gas lasers (carbon dioxide lasers, etc.), and other semiconductor lasers, depending on the material of the generator. .

The materials always produce light of a certain wavelength according to their respective optical properties, and the wavelength determines where the laser is to be used.

The laser is a device that makes light of a certain wavelength very strong and can be used for various purposes depending on the wavelength and energy level.

On the other hand, laser is used in medicine in various forms in modern medicine. Medical applications of lasers, previously limited to the surgical field, have recently been widely extended to non-invasive diagnostic and therapeutic fields. Initially, the laser was introduced into the surgical treatment, and the laser introduced into the surgical field is a laser with a large output energy, and has a tissue destruction effect.

Through this tissue destruction phenomenon, high power laser was applied to tissue cutting, coagulation and hemostasis. As such, lasers, which are widely applied in modern medicine, are used in various ways in skin care.

In the treatment using the above-mentioned laser, conventionally, a laser irradiator that emits a laser is applied to a treatment area of a patient, but the medical staff manually holds the handpiece to which the laser is irradiated.

Therefore, since the conventional treatment is performed manually by a medical staff, there is a problem in that the density emitted from the laser irradiator is not constant.

In addition, when the patient moves to move the skin position to be treated, the treatment should be stopped or followed by treatment along the skin. Accordingly, the posture of the treatment is uncomfortable and there is a high possibility of mistake, the precise treatment is difficult.

In addition, as described above, the treatment handled directly by the medical staff is inconvenient that the treatment cannot be long due to increased fatigue because both the medical staff and the patient have to hang on the treatment for a long time.

In addition, since the medical staff checks the treatment state with the naked eye, there is a problem in that fine treatment cannot be made because the laser intensity cannot be finely adjusted during the treatment.

Currently implemented laser surgical instruments have a rectangular, circular basic irradiation pattern (pattern) frame is determined, and within this range is to be set according to the area to be treated by the practitioner to perform the horizontal and vertical size.

In this setting, depending on the skin color of the person to be treated (the closer the skin color is to black, the intensity of the laser should be reduced, and the closer to the white, the intensity of the laser may be increased. The laser also has the property of light. If the intensity is different, and the purpose of the procedure is to remove scars, spots, erythema, etc., the shape of the procedure (lesion) is all different, and the case of spots is different. Since the degree of pigmentation is different for each part, the operator has to consider the common part and set a part to be treated in consideration of a certain error rate.

In addition, since the skin thickness of the human body is different for each part of the human body and is also different depending on the degree of obesity, the operator is also determined according to the treatment site for the depth of irradiation of the laser and set to a constant value to perform the procedure.

The depth of each part should be clearly recognized and judged by each operator. If there is a mistake, the operator will feel the pain extremely, the result of the procedure may not be in the desired direction, or the procedure will be repeated. May result.

The present invention has been made in order to solve the above problems, attached to the laser irradiator microscopic camera to enlarge the area to be treated to show the image on the monitor attached to the control unit of the laser surgical apparatus, image recognition and color discrimination algorithm Through the built-in operation server, it automatically recognizes the part that needs to be treated, completes the algorithm to adjust the intensity of the laser light through differentiation of skin color of the non-treated part, and precisely shapes the procedure through the shape recognition of the treated part. It aims to provide a system that automatically calculates the intensity of the laser even within the treatment area.

According to the laser treatment system using the skin thickness, color discrimination, and image recognition device according to the present invention, the doctor has to conventionally set the skin color of the subject, the shape of the region to be treated, and the skin thickness of the treatment site. Expert knowledge must be kept at all times, and even if the setting value is correct, the procedure cannot be performed finely and precisely according to the treatment area, and there is always a surgical error value, and if the setting value is wrong, the subject suffers. A significant effect can be achieved to avoid the risk that the patient may feel or need to undergo a retreat or may have a different result than the intention of the operator.
