Description

Continuous laser equipment and new application thereof

Technical Field

The invention relates to the technical field of xerophthalmia treatment equipment, in particular to continuous laser equipment and a new application thereof.

Background

Dry eye, i.e., keratoconjunctival dryness, is a common chronic disease of the eye that results from abnormal tear quality or volume or abnormal kinetics, resulting in reduced tear film stability and reduced tear film rupture time, and the appearance of ocular discomfort. Clinically manifested as eye fatigue, foreign body sensation, dryness sensation, burning, distending pain, photophobia, redness of the eyes, etc., meibomian gland dysfunction is one of the important causes of dry eye.

Intense pulsed light (Intense Pulse Light, IPL) is one of the recommended treatments for dry eye by the international dry eye collaboration group, and is currently the dominant photovoltaic technology used to treat dry eye. It can emit electromagnetic wave with 500-1200 nm wavelength, and can produce heat through selective photothermal action, promote meibomian gland secretion flow, inhibit inflammation effect on meibomian gland, improve meibomian gland function, and has excellent clinical curative effect on dry eye symptoms caused by meibomian gland dysfunction. However, the visible light part contained in the IPL treatment causes strong illumination stimulation to the eye ball, and meanwhile, the treatment parameters needing to be adjusted are more, and the risk of skin burn, red swelling and even blisters of a patient easily occurs when the IPL treatment is not used is present, so that the technical requirement of the equipment on operators is higher.

Based on this, there is a need to propose an optoelectronic therapeutic device for dry eye treatment with high safety and comfort, which avoids or reduces the above drawbacks.

Disclosure of Invention

The invention mainly aims to provide a continuous laser device, which aims to solve the technical problems of strong optical stimulation to eyes of patients, high technical requirements for operators, improper operation and adverse reactions such as skin burn and the like in the dry eye treatment process of the traditional intense pulse optical treatment device.

In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:

the invention discloses a new application of a continuous laser device, which is used for treating xerophthalmia.

The invention also discloses a continuous laser device which adopts a continuous mode to output continuous laser, wherein the wavelength of the continuous laser is 1064nm.

Preferably, the method comprises:

The device comprises a laser generating module, a control module and a control module, wherein the laser generating module is used for generating laser beams, and the control module is mechanically connected with the laser generating module and used for regulating and controlling parameters corresponding to the laser beams generated by the laser generating module.

Preferably, the power of the laser generating module for emitting laser is less than or equal to 10W.

Preferably, the energy density of the laser emitted by the laser generating module is less than or equal to 100J/cm ².

Preferably, the spot diameter of the laser beam is less than or equal to 8mm.

Preferably, the parameters include one or more of power, energy density, spot diameter, and start-stop of the laser beam.

Preferably, the treatment module is used for irradiating the laser beam to the area to be treated;

The laser transmission module is used for transmitting the laser beam generated by the laser generation module regulated and controlled by the control module to the treatment module.

Preferably, the treatment device further comprises an aiming beam module used for assisting the treatment module in aiming the laser beam at the area to be treated, and the control module is electrically connected with the aiming beam module and used for regulating and controlling the beam irradiation intensity of the aiming beam module.

Preferably, the device further comprises a temperature detection module for detecting real-time epidermis temperature of the treatment area.

The invention has the following beneficial effects:

Firstly, it should be noted that, in dry eye treatment, eyelid epidermis is the first tissue that is encountered by light, although it is not the target of treatment, because the intense pulse light treatment device uses the short pulse emission mode, it may cause high temperature peak of epidermis, and thus the skin burns and the side effects such as red swelling and pain appear, while in the present application, it is the continuous emission mode, the laser emission time is far higher than the Thermal Relaxation Time (TRT) of epidermis, and the above-mentioned problems can be effectively avoided, secondly, by adopting the continuous laser with 1064nm wavelength, 1064nm belongs to near infrared range and is not perceived by naked eyes, so that strong light stimulus is not generated to eyes in treatment, and compared with the intense pulse light, discomfort of patients in treatment can be effectively alleviated, and comfort level is improved.

In addition to the advantages described above, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.

Detailed Description

The specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The continuous laser device shown in fig. 1 is applied to treating xerophthalmia in the embodiment, and specifically comprises a laser generating module 100, a control module 200, a laser transmission module 400 and an integrated terminal, wherein the laser generating module 100, the control module 200, the laser transmission module 400 and the integrated terminal are mutually connected to form a complete laser emission path, and specifically

A laser generating module 100 for generating a laser beam;

The control module 200 is configured to regulate parameters corresponding to the laser beam emitted by the laser generating module 100, where the parameters include one or more of power, energy density, spot diameter, and start-stop of the laser beam;

Wherein the laser generating module 100 generates continuous laser light in a continuous mode.

While eyelid epidermis is the first tissue to be exposed to light when dry eye is treated, although it is not the target of treatment, the current intense pulsed light treatment device may cause high temperature spike of epidermis using short pulse emission mode, thus causing red swelling and pain of epidermis burn, etc. side effects, while the present application is a continuous emission mode, the laser emission time is far higher than the Thermal Relaxation Time (TRT) of epidermis, which can effectively avoid the above problems.

Further, as the currently mainstream therapeutic technique, intense pulsed light is an electromagnetic spectrum with a wavelength of 500nm to 1200nm, which contains a large amount of electromagnetic waves with shorter wavelengths, and it should be noted that the shorter wavelengths herein refer to wavelengths in the interval of 500nm to 800nm, which are easily absorbed by melanin in epidermis, which increases the risk of thermal damage to epidermis, especially in individuals with darker complexion, which may cause pain, even more serious side effects such as redness, blisters, etc.;

In this embodiment, the wavelength of the continuous laser is 1064nm because the electromagnetic wave melanin absorption rate at 1064nm is low, and the laser can penetrate into the dermis to be absorbed by the chromophore such as hemoglobin to generate heat energy, thereby affecting the dermis blood transport and meibomian gland function. In addition, the 1064nm is in the near infrared range and is not perceived by naked eyes, so that strong light stimulus is not generated to eyes during treatment, and compared with strong pulse light, the discomfort of patients during treatment can be effectively relieved, and the comfort is improved.

For those skilled in the art, the preferred values of the parameters are that the power of the laser emitted by the laser generating module 100 is less than or equal to 10W, the energy density is less than or equal to 100J/cm ², and the spot diameter of the laser beam is less than or equal to 8mm, and it should be noted that the range of the parameters is mainly set to avoid the harm of the laser beam to the patient in the use process, and improve the safety in the use process.

Furthermore, the device further comprises a laser transmission module 400 for transmitting the laser beam generated by the laser generating module 100 regulated by the control module 200 to the integrated terminal, wherein in this embodiment, the integrated terminal comprises a treatment module 300 and an aiming beam module, the treatment module 300 is used for irradiating the laser beam to the area to be treated, in this embodiment, the treatment module 300 adopts a treatment tool, the treatment tool can be understood as a handheld laser emitter so as to facilitate the laser beam transmitted by the laser transmission module 400 to irradiate the area to be treated of the patient, and in this embodiment, the treatment module 300 is further provided with the aiming beam module for assisting the treatment module 300 to aim the laser beam at the area to be treated, meanwhile, the control module 200 is electrically connected with the aiming beam module for regulating the beam irradiation intensity of the aiming beam module, and in this embodiment, the beam of the aiming beam module is a visible infrared light beam with the power of less than or equal to 1mw and the wavelength of 650 nm.

The integrated terminal further comprises a temperature detection module 500 for detecting real-time epidermis temperature of the treatment area, so that local skin temperature can be monitored in real time, and pain and epidermis burn of a patient are avoided.

To further illustrate the working principle of the present invention, referring to fig. 2, first, the laser generating module 100 selects appropriate parameters under the adjustment of the control module 200 to generate a continuous laser with a certain intensity, where the "certain intensity" specifically selects corresponding parameters according to the patient's condition, and the specific parameter criteria are as described above, and then the parameters are transmitted to the treatment module 300 under the transmission of the laser transmitting module 400 (actually, a transmission member such as an optical cable), where in this embodiment, the treatment module 300 employs a handheld type with the aid of an aiming beam module, so as to accurately strike the laser beam to the area to be treated, and in addition, in order to avoid pain and skin burn caused by the laser beam to the patient during the treatment, a temperature detecting module 500 is configured on the treatment module 300 to detect the real-time temperature of the skin of the treatment area.

In order to further verify the superiority of the technical scheme, trial treatment is carried out on part of xerophthalmia population, as the device is not produced in batches yet, and large-sample clinical observation is not carried out, the curative effect index is mainly subjective symptoms before and after treatment of patients, and visual expression is carried out through the percentage of comfort;

1. the eyes are obviously dry and astringent, and the fatigue (blood streak) is less than or equal to 50 percent and less than 70 percent;

2. eyes are slightly dry and astringent and fatigue is less than 85% and more than 70%;

3. Eyes are not dry and tired and are not dry and not more than 85 percent;

The following table shows a comparison of the use of the present device with existing IPL devices for different people. In order to avoid ambiguity, in the questionnaire, the minimum value is preset to be 50%, that is, the surveyor performs scoring according to own experience, and the score range is 50-100;

firstly, it should be noted that this form is a representation of a sampling survey and subjective perception, so that such data is only used as a reference, and the comprehensive form expresses that the patient can have a better experience during the treatment, and can avoid the "stress" caused by the "light" to the patient to a certain extent, and secondly, the maintenance time is longer during the subsequent ocular treatment by adopting the scheme of the present application.
