The present application claims priority to Korean Patent Application No. 10-2023-0026459, filed Feb. 28, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to a device and, more particularly, to a laser irradiation device for medical treatment.
In general, laser treatment using lasers is widely known for treating skin problems and conditions such as freckles, age spots, and blemishes. Currently, as a new skin treatment using lasers, a method of creating hundreds to thousands of microscopic treatment zones in the skin and performing laser treatment on each microscopic treatment zone is gaining popularity.
Laser irradiation of hundreds to thousands of microscopic treatment zones is carried out by forming multiple laser spots on a treatment target, and conventionally, the laser spots are formed using a laser scanner device. However, since the laser scanner device does not form multiple spots at the same time, but forms multiple spots with a time difference, the laser scanner device has the disadvantage of making it difficult to perform treatment quickly and is not easy to operate.
Recently, a laser device system that implements multiple spots using a microlens array has been introduced (Korean Patent No. 0720868). This is a technology that creates multiple spots by forming a plurality of microlens arrays and passing a laser beam through the arrays, so that a large number of beams are emitted. However, in this case, forming a microlens array and adjusting the spot size or laser intensity are not easy. Moreover, since the laser intensity for individual spots in the entire irradiation area is not uniform, effective treatment is difficult to achieve.
Meanwhile, the above-mentioned conventional laser equipment for medical treatment uses beams provided by means of a resonator in an optics unit to treat a patient's affected area. Especially, in the treatment range of 500 to 3,000 nm, which is the near-infrared wavelength treatment range of medical laser equipment, the shape of the beam generated by configuring a laser resonator to be used as a therapeutic laser is a circular with a diameter of about 0.5 to 15 mm. In addition, the beam is formed as a centrally focused Gaussian beam (TEM00) or is formed to have uniform fluence like a TopHat beam.
However, in traditional laser treatment, a method of direct emission of the beams provided through the resonator in the optical unit has the disadvantage of long downtime and slow regeneration. Accordingly, a new type of fractional laser system with a short treatment time, less pain, and rapid regenerative effects has become necessary.
While the fractional laser system has the advantage of being able to irradiate the skin evenly and requiring a short treatment time, the emission range is not constant and refraction occurs depending on the light entering a lens. In order to solve these problems, a lens that can emit light to the desired point regardless of the angle at which the light enters is inserted and used. The problem is that depending on the size of the laser and the irradiation range, there are laser blind spots on the skin that cannot be irradiated.
Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and the present disclosure is intended to provide a laser irradiation device for medical treatment that enables a user to set the desired shape of a laser beam, the number and intensity of laser beams delivered by range, and is capable of irradiating the skin, even to laser blind spots on the skin that could not be irradiated by finely adjusting the shapes of laser beams.
Objectives of the present disclosure are not limited thereto, and other objectives not mentioned will be clearly understood by those skilled in the art from the following description.
In order to achieve the above objective, according to an embodiment of the present disclosure, there is provided a laser irradiation device for medical treatment for irradiating a laser treatment target with a laser beam, the device including: a handpiece configured to irradiate the laser treatment target with a laser beam in a preset guide shape; and a controller configured to set, on the basis of data on the laser treatment target, a guide shape for emitting a laser beam and generate a control message to control an operation of the handpiece on the basis of the guide shape.
In this case, the handpiece may include: a scanner that is disposed inside the handpiece, includes at least one mirror, and determines a location where the laser beam is emitted on the basis of the preset guide shape.
In this case, the handpiece may further include: an imaging part that is disposed on an outside the handpiece, and acquires medical image data by photographing a face of the laser treatment target; and a motion sensor module that is disposed on a side of the handpiece, detects movement of the handpiece, and acquires motion data.
In this case, the data on the laser treatment target may include at least one of a treatment case of the treatment target that has already been stored or newly input, medical image data of the treatment target, and treatment conditions of the treatment target.
In this case, the controller may extract position coordinate values of individual facial components from the medical image data, and set a plurality of facial areas using the extracted position coordinate values.
In this case, the controller may distinguish between an irradiation area and a non-irradiation area from the facial areas, and set, in a circular or polygonal laser beam shape, a shape excluding the non-irradiation area as a guide shape for delivering a laser beam.
In this case, the scanner may further include: a mirror drive part connected to the mirror and changing a position and an angle of the mirror, wherein the mirror drive part may receive the control message from the controller and adjust the position and the angle of the mirror to a preset position and angle according to the guide shape.
In this case, the controller may recognize at least one facial area where a laser treatment has been completed from the plurality of facial areas on the basis of the acquired motion data.
In this case, the controller may establish a treatment plan for each area of the plurality of facial areas, wherein the treatment plan may be a planned sequence for each of the facial areas so that a first facial area where a first laser treatment is completed and a second facial area where a second laser treatment will be performed after the first laser treatment do not overlap.
In this case, the handpiece may further include: a notification part that is disposed on the outside the handpiece, and provides notifications to an outside using sound or light, and the controller may transmit a control message to the notification part to provide notifications when a position coordinate value of a first facial area where a first laser treatment is completed and a position coordinate value of a second facial area where a second laser treatment will be performed after the first laser treatment overlap.
As described above, according to embodiments and various aspects of the present disclosure, since the shape, irradiation range, number, intensity, etc., of laser beams required according to a patient's condition can be set, side effects due to individual skin conditions can be minimized.
Furthermore, according to the present disclosure, since the beam shape and laser intensity can be finely adjusted corresponding to the location and shape of various treatment target areas to deliver lasers without laser blind spots, treatment effect can be improved.
The effects of the present disclosure are not limited to the above effects, but should be understood to include all effects that may be inferred from the configuration of the invention described in the description or claims of the present disclosure.
The above and other objectives, features, and other advantages of the present disclosure will be more clearly understood from the following detailed description when taken in conjunction with the accompanying drawings, in which:
