Description

The wide Nd:YAG laser depilation beauty treatment of long pulse machine

Technical field

This utility model relates to the laser beautifying apparatus, is specifically related to a kind of laser depilation beauty therapeutic machine that is used for, and belongs to International Classification of Patents A61B18/00 " to human body or transmit surgical instruments, device or the method for on-mechanical form energy from human body " technical field.

Background technology

Laser depilation has been carried out decades, uses ruby laser the earliest, and Alexandrite laser is used in the back again, adopts intense pulsed light (IPL) and 808 Nano semiconductor laser in recent years.For the darker crowd of skin, the ultimate challenge that the acquisition permanent hair removal runs into is in order to destroy hair follicle tissue, mainly to utilize the absorption of melanin to light, it is warmed up to more than 70 ℃, causing albuminous degeneration and necrosis.Yet the dark crowd of melanin, the especially colour of skin of equally also distributing in epidermis, melanin concentration is very high in the epidermis.General hair follicle is positioned at 2-5 millimeter under the epidermis, and light at first must pass epidermis if can arrive hair follicle.Intraepidermal melanin is extinction and heating up at first.Therefore for guaranteeing that epidermis does not damage, hair follicle just can be not downright bad yet.For the casting skin crowd being realized permanent hair removal guarantees epidermis safety again, require the laser can be by melanin absorption but can not absorb too by force, its less important reinforcement is to the brute force cooling of epidermis, and the 3rd is suitably to widen laser pulse width, reduces its intensity.Make the heat that produces behind the epidermis extinction be taken away and maintain the temperature at below the safety value by refrigerator successively, because that hair follicle is positioned at is subcutaneous, the heat that produces behind the extinction is difficult for lost and persistently overheating, until necrosis.The wide Nd:YAG laser of long pulse can satisfy above-mentioned every requirement.Safest permanent hair removal means have been acknowledged as to coloured skin crowd.Corresponding laser instrument is not succeeded in developing as yet, has limited the enforcement and the popularization of this technology but at present.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of wide high-energy N d:YAG laser instrument of long pulse that can be used for the safety permanent depilation of coloured skin is provided.

The purpose of this utility model is achieved through the following technical solutions.

The wide Nd:YAG laser depilation beauty treatment of a kind of long pulse machine comprises Nd:YAG laser instrument, Transmission Fibers and laser therapy handle three parts composition; The Nd:YAG laser instrument mainly comprises the sealing head, is arranged with completely reflecting mirror adjustment rack, diffuse-reflective cavity, outgoing mirror adjustment rack and coupled lens adjustment rack in the sealing head; Two placed in-line xenon flash lamps and Nd:YAG rod are equipped with in the diffuse-reflective cavity end; Sealing head front end is useful on the turnover plug that connects power supply and recirculated water, and the sealing back-end of machine head has fiber-optical socket, and by fiber-optical socket to laser therapy handle output lead, lead to the lead connection Transmission Fibers of treat handle, enter the laser therapy handle.Leaded light piece lens are arranged in the leaded light piece of therapy apparatus handle; Leaded light piece rear end be respectively equipped with one, two or three plug-in mounting leaded light pieces outstanding.By the external water circulating pump of sealing head front end recirculated water turnover plug, its current lift is greater than 10 meters.

The laser therapy handle comprises shell, and there is sapphire refrigeration window the shell front portion, and the rear end of sapphire refrigeration window places in the handle casing, connects leaded light piece lens, and leaded light piece lens back connects Transmission Fibers and output.

Described diffuse-reflective cavity adopts quartzy hard-pressed bale diffuse reflecting pump cavity, and intracavity is equipped with two placed in-line xenon flash lamps and Nd:YAG rod, and the thickness of intracavity cooling water layer is no more than 2.5mm.

The external power supply of this laser instrument adopts temporary ripple discharge to add the negative feedback circuit, and laser is output as the flat-top square wave, and laser pulse width can reach the 10-300 millisecond, and laser instrument output energy is greater than 55 joules.

This utility model is used for permanent hair removal, removes shank varicosis, and a treatment such as blood capillary proliferation also can be used for general skin care, comprises and dispels tiny wrinkle, thick pore etc.Its working stability is reliable, and especially as safe as a house to the permanent depilation of casting skin crowd, effect is fairly obvious again.Be at first to succeed in developing the wide high-energy N d:YAG laser instrument of the long pulse that can be used for the safety permanent depilation of coloured skin at home, its pulse width is adjustable from the 10-300 millisecond.The exportable 1-3 of an each flash of light pulse, pulsewidth and adjustable at interval.Especially Shu Chu laser is the flat-top square wave, and this is very favourable to the safety of losing hair or feathers, and does not appear in the newspapers as yet both at home and abroad.That further succeeds in developing has leaded light piece, a refrigerating treatment handle of contact, by changing the leaded light piece, thereby can change the laser parameter that treatment spot size and energy density provide the treatment various disease conditions easily.
