Description

Technical Field [0001] The present invention relates to a non-invasive foot-and-foot ulcer treatment apparatus using a 3D scanner-based laser or an LED light source,

The present invention relates to a non-invasive medical treatment apparatus for efficient light treatment of a diabetic foot ulcer.

Diabetes is a typical metabolic disorder that occurs when insulin protein secretion in pancreatic cells is poor or secreted insulin protein fails to function normally due to various causes. Diabetic patients have peripheral neuropathy and vascular disease, which is responsible for one third of the patients experienced foot ulcers. People with diabetes have a lifetime risk of about 15% of foot ulcers. In addition, more than 50% of patients require medication for infection. Foot infections due to diabetic foot ulcers may also be a major cause of limb amputation.

For the treatment and prevention of diabetic foot ulcers, bilateral treatment, oriental medicine treatment, Complex risk factors such as structural deformity and trauma of the foot caused by diabetes increase the incidence rate. In addition, secondary causes due to vasculopathy and local infection are also difficult to treat. These various risk factors are difficult to overcome with a single therapy, and a variety of collaborative treatments are needed.

In this sense, a variety of noninvasive oriental herbal therapies have recently attracted attention. In particular, it has been proved that the acupuncture stimulation using physical acupuncture can be realized by using the high coherence and accumulation of the laser, and laser acupuncture has become a new acupuncture tool that complements the disadvantages of traditional acupuncture. Laser saliva not only proves the existing physical invasive principles and effects, but also shows the broad effect of phototherapy. Phototherapy is a treatment using various light sources such as laser and LED. It is a treatment that can restore the damaged skin tissue by utilizing the light activated action of cells in the skin tissue. In addition, noninvasive saliva (laser / LED) has the advantage of being able to be treated without physical contact. This can also help to treat common foot infections for diabetic foot lesions. Although diabetic foot infections differ according to their severity, they are generally found to be aerobic gram-positive cocci and gram-negative bacilli, and in the case of chronic diabetic foot infections, Some bacteria are found together. Therefore, a light source such as a laser beam can have a great effect. That is, there is no risk of infection due to secondary mediator, and there is an advantage that it can be performed in a relatively easy and economical manner.

In recent years, a variety of light sources have been used for noninvasive needles. Despite these advantages, there are major problems with currently developed and implemented products.

A variety of light sources may be used in this therapy. He-Ne and Ga-As low-power lasers are effective for peripheral stimulation, wound healing, and suppression of control. Recently, LED light source is also applied to various skin diseases. In case of LED light source, light energy reaches a wide area with appropriate light output compared to laser, and has a narrow wavelength bandwidth, which is effective as a light source for a therapeutic power of low output. In the case of a laser, it has been pointed out that a large volume and heat generation are problematic depending on the type and wavelength of a light source. However, the LED has a long life and low power consumption and a small volume.

Despite the variety of light sources, the effects of foot ulcers on the light source have been reported variously. The therapeutic effect in various diseases including diabetic foot ulcers is widely known to depend on the wavelength of the light source, the dose, intensity, time and method of irradiation. Phototherapy for diabetic foot ulcers is known to be effective for wound healing and cell regeneration, but it depends not only on the wavelength of the light source, light intensity, irradiation time and area, but also on the individual differences of the foot ulcer tissues The effect can vary.

The wavelength, the initial light intensity, and the irradiation time can be adjusted according to the electromagnetic characteristics of various light sources, but there is a problem that the irradiation distance between the light source and the affected part varies depending on the infiltration depth of the foot ulcer tissue and the shape of the tissue . Conventionally, it has been impossible to perform laser treatment while keeping the irradiation distance to the affected part of the medical practitioner constant. In some portable laser products, there is a collimator that can maintain the gap between the laser needle and the affected part, but in this case, it is in contact with the affected part, which causes infection.

It is an object of the present invention to provide a therapeutic device for maximizing the therapeutic effect of a diabetic foot ulcer by transmitting a laser or an LED light source to the affected part of a diabetic foot ulcer noninvasively at a certain distance and at an optimum angle.
