Description

Laser physiotherapy device

Technical Field

The invention relates to the technical field of laser medicine, stomatology and maxillofacial surgery, in particular to a laser physiotherapy device.

Background

In 1931 the German scientist Otto Warburg gained a Nobel prize for physiology and medicine by discovering that biological cells oxidize and enzymatically catalyze, and among them, he also discovered that certain frequencies of light can stimulate and accelerate the activities of the inside of cells, and these discoveries also become the basis of photo-biological regulation therapy in modern medicine.

Endre Mester, Hungarian scientist, discovered in 1967 the biological effects of low-power infrared laser light, his rat experiment showed rapid growth of tissue irradiated by this laser light, and in the same year he published his research result, a research paper on "biostimulation effect of low-power laser light", which he subsequently used for clinical medical research and in 1971 low-power laser light for the treatment of patients with non-healing skin ulcers, whereby the established low-power laser treatment method was well known.

Modern scientific research shows that light in red light and near infrared light bands with wavelength of 600-950 nm can penetrate human skin most easily, laser in this band can penetrate human soft tissue to several cm depth and the penetration depth is related to wavelength, power and other factors, when the wavelength is 600-700 nm, the light can penetrate skin to 1 cm or more deeply, and when the wavelength is 780-950 nm, the light can penetrate soft tissue to several cm range, after the soft tissue is irradiated by the laser, the light can be absorbed by tissue and mainly acts on mitochondria in cells, which are functional parts of energy of palm tube in cells, under the action of the laser, the capability of the cells to generate energy is improved, the metabolism is promoted, the overall efficiency of the cells is improved, so the biological effect is expressed in activating cell function, enhancing human immunity, Promoting healing, growth and restoration of injured tissue and thus also promoting and accelerating tissue remodeling is the "photo-biological effect" of such lasers, in contrast to the "photosynthesis" that occurs in plants, which is well known to be another photo-biological effect.

Low Energy lasers, also known as LLL, are used for therapeutic purposes, and have a Laser power of between 5mW and 500mW, and do not generate heat when applied to tissue, but only produce the above-mentioned biological effects, and are therefore also called Cold Laser or Soft Laser, and when used as a therapeutic means, they are "Low Energy Laser therapy methods", i.e. LLLT (Low Level Laser therapy), and are also called "photobiomodulatology", i.e. Photobiomodulation, and current research and clinical practice has proven that LLLT methods are effective for pain relief, swelling reduction, inflammation reduction, wound healing promotion, and tissue reconstruction, and many such Laser devices are in practical use, such as handheld products of Energy Laser, e.g. dalm Laser, and further such as split Laser physiotherapy instruments of the united kingdom, such as two-in-one dental Laser zr, can be used as a laser scalpel for gingival soft tissues and has the LLLT physical therapy function.

LLLT is currently available for many applications in the medical field of oral and maxillofacial surgery, such as: dental movement in orthodontic treatment, osseointegration in dental implants, pain relief after tooth extraction, promotion of wound healing after oral surgery, temporomandibular joint dysfunction, and the like.

Orthodontics is correcting teeth and relieving malocclusion deformity of a patient, and the orthodontics utilizes plasticity of jaw bones, applies external force to malocclusion and tooth with malformed arrangement by means of correction tools and devices to move the teeth and reconstruct jaw bones, and finally achieves the purposes of neat tooth arrangement and harmonious and beautiful face, but the orthodontic treatment process of the teeth is long-lasting, generally requires 2-3 years and even longer time, so people always seek a method for accelerating the orthodontic treatment process, currently, laser orthodontic accelerators utilizing a LLLT method are in practical use, for example, Ortho pulse products of Biolux Research company of Canada, obtain FDA marketing permission in 7 months of 2015, are LLLT laser physiotherapy products special for orthodontic acceleration, use near infrared laser with a wavelength of 850 nanometers, laser irradiation plates easy to match with the shape of dental arches can be contained in mouths to irradiate periodontal tissues, the use of the product can shorten the orthodontic treatment time 1/3 or more.

Currently, the LLLT laser medical device in practical use is mainly in the form of an integrated handheld type (similar TO a straight flashlight or an elbow flashlight) and a split type pen-shaped emitter, wherein the irradiation area of the integrated handheld type laser medical device is larger, the irradiation area of the split type laser medical device is smaller, most of semiconductor laser generators, namely laser diodes, used by the laser physiotherapy instrument are in a classical style, a single laser beam is formed by using a single laser diode, or a plurality of laser beams are formed by using a plurality of laser diodes and dozens of such laser diodes, therefore, in the case of single laser beam, if one area is irradiated, a scanning action is required, the laser diodes are generally large in size and cannot be easily made into surface-mounted elements, of course, the laser diodes are of a few varieties, the most typical packaging form is a TO-CAN packaging, and the most typical packaging form is a metal cup-shaped packaging with a diameter of several millimeters, The laser irradiation device is provided with a plurality of extraction electrodes, a round hole is arranged at the bottom of the cup to be used as a laser emission window, the driving voltage is from a few volts to 20 volts, and the emission power is from dozens of milliwatts to several watts, so that the laser irradiation device is not suitable for LLLT medical application of area irradiation in many models.

In the last 1977, the japanese scientist Kenichi-iga proposed a VCSEL semiconductor Laser generator for the first time, and the VCSEL, i.e. Vertical Cavity Surface-Emitting Laser, means "Vertical Cavity Surface-Emitting Laser", and a Laser diode manufactured by the technology can realize small-volume, low-voltage driving and more stable Laser emission, so that a tiny Surface-mounted component can be conveniently manufactured, and an integrated circuit containing a plurality of Laser diodes can also be manufactured, which opens up a new place for the LLLT medical purpose and the area irradiation type Laser medical technology, and since 2000, VCSEL Laser diode varieties appear on the market, and suppliers and product varieties continue to increase after 2010.

The LLLT laser physiotherapy product form in practical use has the characteristic of universality, namely, the LLLT laser physiotherapy product form can be used for different parts of a human body, but when the LLLT laser physiotherapy product form is used for medical treatment, including orthodontic treatment acceleration, a patient needs to go to a hospital or a clinic for a doctor to see a doctor and be irradiated by medical care operation, and OrthoPulse is one of the rare exceptions at present: the LLLT laser physiotherapy device is a professional LLLT orthodontic acceleration physiotherapy instrument, can be used by a patient at home, can only be used for orthodontic acceleration but not for other treatment or auxiliary treatment purposes, and the laser specification, namely the technical parameters such as the wavelength of laser and the like, and the size or the irradiation area of a laser irradiation point of all the LLLT laser physiotherapy devices are generally fixed, can not be selected or adjusted or only have very limited adjusting functions, so that the LLLT laser physiotherapy device has no flexibility or weak applicability in many occasions requiring laser irradiation treatment and is difficult to meet many related or similar specific requirements.
