Description

[0001] The present invention relates to a laser medical appliance using a thermoelectric element,

The present invention relates to a laser therapy apparatus as a medical device, and more particularly, to a laser therapy apparatus for use in a medical device, in which a thermoelectric element for combining a water-cooled type and an air-cooled type is used as a chamber provided in a head of an optical portion, And to a laser therapy apparatus using a thermoelectric element that can be controlled in conjunction with a stimulator.

Various methods are currently being tried to treat skin such as acne treatment, pore reduction, wrinkle removal, scar removal. In general, the delivery of the cosmetic or drug through the skin is very poor in absorption rate due to the difficulty of the drug penetrating the stratum corneum. Particularly, when the molecular weight is large, the absorption rate is further lowered. Therefore, there is a limitation in transferring a drug substance or a nutrient substance through the skin to the dermis so as to regenerate or treat the skin. Especially, the larvae having a large molecular weight can not be transmitted to the dermal layer.

To improve this, a technique using a micro needle (which is sometimes referred to as a "micro needle" in the industry), which is a method of stimulating the skin with a thin needle, has been developed and is now being widely used. This method uses a plurality of microneedles to form an artificial wound that passes through a part or all of the epidermis layer and reaches the epidermis beyond the skin epidermis. Due to the natural healing ability of the human body, these wounds come up with new flesh. In this process, activated aging collagen is activated and has elasticity, so that wrinkles and scars of the skin are treated.

In addition, the wound by the microneedle as described above forms a channel reaching the dermal layer of the skin (the wound of the eye of a needle) and transfers a drug substance or nutrient to the skin layer or the lower layer through the channel, The effect is also increased. For this reason, many medical and cosmetic devices using micro needles are currently being developed.

However, in the treatment with this micro needle, the temperature of the saliva increases by the skin temperature (36.5 ° C) during the procedure, and there is a risk of infections due to the temperature at which the germs and the like become active in the saliva. The biggest problem is the accompaniment of pain due to acupuncture penetration. No matter how small it is, if several people penetrate the skin at the same time, the pain is doubled. And the conventional microneedles are most commonly used in the form of a roller-shaped micro needle. By pushing the rollers, a large area can be easily manipulated. However, it is accompanied by excessive injury.

Therefore, until the spread of high-frequency deep rejuvenation, removal of skin, scar treatment, etc. Laser or chemical-based dressing or deep regeneration has been used. However, the principle of promoting collagen production by artificially damaging the skin is only the difference of the depth depending on the type of depilatory before it. This is safe and effective deep rehabilitation is also accompanied by the burden of having to undergo general anesthesia and pain for one to two weeks after the procedure, and there are side effects such as burning sensation, There are some difficulties for those in the process.

On the other hand, the principle of deep rejuvenation by radio frequency (RF) is that the wavelength of strong radio waves reach deep into the skin by using high frequency, but the subcutaneous dermal layer temperature instantaneously rises to 45 ~ 50 ℃ . As the temperature of the skin increases, the capillary blood vessels expand, the blood circulation is promoted, the aged collagen is activated, and not only the elasticity of the skin is restored, but also induces the generation of new collagen, thereby improving the skin and wrinkles. Especially, 0.1 ~ 0.8MHz for high frequency is suitable for human body treatment.

As described above, many researches and developments have been made on the permeation of RF waves to the skin to promote the activity of the skin, and the effect of the RF waves on skin activation has been recognized in the registered utility model 20-0426759.

However, RF waves are a kind of electromagnetic waves, and when they are propagated from one medium (air) to another medium (skin), most of them are reflected at the interface (skin surface) of the medium, and the amount of penetration into the medium is very small. Therefore, in order to be able to treat the skin, it is necessary to irradiate the skin with a RF energy of a very high energy, which causes a problem such that the energy consumption is high and the RF wave generator is overheated. Thus, the strong RF wave affects the operator and the patient badly . In addition, there is a problem that malfunctioning of the surrounding electronic device occurs.

The thermoelectric element used in the present invention is a kind of semiconductor using a thermoelectric effect. The thermoelectric phenomenon refers to the energy conversion between electricity, and when there is a temperature difference between both ends of the conversion element, a carrier inside the device moves, causing a current to flow and a voltage difference (electromotive force) is generated. This phenomenon occurs in the opposite way. If there is a voltage difference between both ends of the thermoelectric element, the both ends of the thermoelectric element will have a constant temperature difference. These thermoelectric phenomena can be classified into the Seebeck effect and Tomson effect, which obtain the electromotive force using the temperature difference between both ends, and the Peltier effect, which is cooled and heated by the electromotive force.

Utilizing these Peltier effects, humidifiers, CPU coolers, coolers, and refrigerators are in practical use close to everyday life. Plans are underway for nuclear submarine power generation, seawater temperature difference power generation, and solar power generation.

Such a thermoelectric element is a next generation cooling substrate for simple and reliable exchange of heat and electricity that can simultaneously achieve cooling, heating, constant temperature and power generation by supplying a DC power using a thermoelectric material. And the temperature can be maintained at a constant temperature within an error range of +/- 0.03 ° C according to the control technology applied to the thermoelectric device.

Therefore, such a thermoelectric element can be downsized, which makes it easy to mount the thermoelectric element on precision instruments and the like. It is possible to precisely control the temperature due to the simultaneous heat generation and cooling, and it is possible to cool the local part with the simple DC power supply, and there is almost no noise. In addition, it is an environmentally friendly technology product that can be cooled and heated at the same time from the minimum width and length of 0.8cm x 0.8cm to the local site and a wide range, and is freed from freon which is widely used for cooling.
