Description

A kind of laser therapy handle

Technical field

This utility model belongs to the laser medical equipment field, is specifically related to a kind of laser therapy handle.

Background technology

Along with the development of laser technology, be widely used in medical science shaping and beauty industry at present.When carrying out laser surgery, laser can produce the hot injury to skin to the heat effect that skin produces, and postoperative is chromogenesis deposition very easily also; Because the hot injury also makes the dosage of laser irradiation obtain restriction, can't carry out efficacious therapy in addition to deep skin.

In order to prevent skin heat damage, when laser surgery, generally can take skin is carried out refrigerative measure, mainly contain several kinds of modes such as precoating epoxy resin, sapphire contact cooling, air-cooled, coolant spray cooling at present.

The mode of precoating epoxy resin not only can be polluted skin surface, and with the contact skin time long after, cooling effect decreases; The sapphire contact cooling needs cooling back installation, and contact window and skin have thermal contact resistance can not realize fast cooling; The air-cooled equipment that air-cooled needs are special, cost is high.Dynamically the coolant spray cooling does not need continuous cooling, only need before laser emitting, carry out the short time spray cooling and get final product, and has dynamic; The absorption heat is big, and rate of cooling is fast; Safety and sanitation, energy-conserving and environment-protective, but existing product complex structure cost is expensive.When carrying out laser surgery treatment, the area in affected part or effect organize different needs to select different big or small treatment hot spots for use in addition, and the existing product spot size is single, or realize the spot size conversion through changing special light-conducting system, the expensive use inconvenience of cost.

The utility model content

For overcoming deficiency of the prior art; This utility model aims to provide a kind of laser therapy handle, and this laser therapy handle has and can realize the dynamic spray cooling of agent to skin, realizes the conversion of treatment hot spot; Hot spot and cooling spray can act on same therapentic part; Have simple in structure, easy switching, the advantage of easy operating.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, this utility model is realized through following technical scheme:

A kind of laser therapy handle comprises the one handle shell, is provided with a holder in the said handle casing; Said holder is provided with a movable block; Said movable block is provided with an electromagnetic valve, and an end of said electromagnetic valve connects a nozzle, and the other end connects a conduit; Also be provided with a lens barrel in the said handle casing, an end of said lens barrel is connected with an optical fiber, and other end below is provided with the adjustable support frame of an adjustable length, and said adjustable support frame is connected on the said handle casing.

Further, be fixed with first lens and second lens successively along its centrage in the said lens barrel.

Further, said movable block can be along the parallel change fixed position of moving or rotatablely move of said holder.

Preferably, the response time of said electromagnetic valve is less than 10ms.

Preferably, the nozzle diameter of said nozzle is 0.1-3mm.

Further, the centrage of said nozzle and the centrage of said lens barrel have angle crossing, said angle greater than 0 ° less than 90 °, and intersection point is positioned on the bottom surface of said adjusting spike.

Compared with prior art, the utlity model has following beneficial effect:

This utility model can be realized skin is realized dynamic spray cooling when carrying out laser surgery, prevent that skin is injured; Can regulate the treatment spot size, and can guarantee that cool position is identical with facula position, have simple in structure, hot spot is adjustable, the advantage of easy operation, skin good cooling results.

Above-mentioned explanation only is the general introduction of this utility model technical scheme, in order more to know the technological means of understanding this utility model, and can implement according to the content of description, below with the preferred embodiment of this utility model and conjunction with figs. specify as after.The specific embodiment of this utility model is provided by following examples and accompanying drawing thereof in detail.
