Abstract

The invention relates to a hair laser photocoagulator which is mainly composed of a laser generator, a control switch, light guiding fibers, a handle, a power line and a power plug. The laser generator can generate pulsed laser and the pulsed laser is transmitted to target tissues by the light guiding fibers. The front ends of the light guiding fibers can pierce into eyelash follicles to directly send laser to the roots of eyelash and accurately break the roots of the eyelash, which are rich in melanin, and surrounding tissues do not contain the melanin or contain the melanin a little and adsorb laser energy a little, and thus, the surrounding tissues are difficult to break by the laser energy. Generation of complications is reduced.

Description

Hair laser photocoagulator

Technical field

The present invention relates to technical field of medical instruments, the instrument and equipment used in a kind of clinical ophthalmology treatment, specifically a kind of laser photocoagulator for the treatment of trichiasis.

Background technology

Trichiasis are external ophthalmopathies more common in children and adolescents and old people.Trichiasis refer to that eyelashes rearward grow, so that touch the disease of eyeball.Under the friction that eyelashes are long-term, conjunctival congestion, corneal epithelium point-like or diffuse damage, corneal ulcer, finally causes visual deterioration, and severe patient even causes blind.

The mode of current treatment trichiasis mainly contains: pull out merely, the Therapeutic Method such as electropolishing treatment, laser photocoagulation, high frequency ablation art and surgical operation.Wherein pull out merely simple to operate, easily implement, but it is high to pull out merely relapse rate.Along with the development of laser technology, the application of laser in clinical treatment is more and more extensive.1979, the trichiasis of Berry first Application Argon laser treatment, after this method became the common method for the treatment of trichiasis gradually.Current clinical treatment is: hair follicle root aiming light being focused on trichiasis, make laser via coaxial with the eyelid subcutaneous of eyelashes, first employing diameter is the hot spot of 50 μm, and slap shot hair follicle root becomes crateriform, diameter is selected to be the hot spot slap shot of 200 μm again, until hair follicle destroys.

Current clinical laser therapy trichiasis technology used, postoperative meeting forms crateriform destruction region at trichiasis root, damage is large, patient suffering is heavier, treatment required time long (average every root trichiasis about need 1 minute), clinical manipulation is complicated, and easily causes the adverse consequences such as local scar formation, margo palpebrae depression, lid abnormity, entropion.Laser therapy trichiasis technology can not by the main cause promoted rapidly just for this.So we need a kind of site of action more accurate, damage less, complication is less, operates easier laser therapy instrument.Can cure rate be improved like this, reduce the incidence rate of complication simultaneously.

Summary of the invention

The object of this invention is to provide a kind of novel hair laser photocoagulator, Eyelash follicle can be destroyed accurately, and not damaging surrounding tissue.

The technical solution adopted for the present invention to solve the technical problems is: this hair laser photocoagulator is made up of laser generator, gauge tap, optical fibers, handle.

Described laser generator can produce pulse type laser, is sent to destination organization by optical fibers.Laser generator can launch pulse and multi-pulse laser, and the pulsewidth of laser and energy can need to carry out free adjustment according to difference.

Optical fibers one end connects laser generator, and other end cover has handle, facilitates positioning action.

In use procedure, optical fibers front end is thrust bottom Eyelash follicle, open gauge tap, laser pulse is produced by laser generator, arrived the hair follicle of target eyelashes by optical fibers, accurately destroy and be rich in melanic eyelashes root, and surrounding tissue does not contain or seldom contain melanin, little absorbing laser energy, thus not easily destroy by laser energy.Decrease the generation of complication.

Hair laser photocoagulator of the present invention overcomes prior art defect, has the following advantages:

(1) laser pulse arrives the hair follicle of target eyelashes through optical fibers, accurately destroys and is rich in melanic eyelashes root, avoids destroying the epidermis of shallow table, mucosa and shallow-layer soft tissue, decreases the generation of complication.

(2) laser pulse selectively acting is in eyelashes root, and required energy is less.

(3) optical fibers front end can be thrust in hair follicle, accurate positioning, and every root trichiasis only need several laser pulse to complete single therapy, so therapeutic process is simple and efficient.

Accompanying drawing explanation

Included accompanying drawing is used for understanding the present invention further, and its ingredient as description also explains principle of the present invention together with description, and non-limiting statement.

In the accompanying drawings:

Fig. 1 is embodiments of the invention structural representations;

Fig. 2 is the profilograph of the example handle shown in Fig. 1;

Fig. 3 a-c illustrates the sectional view of the front end of described optical fibers alternate embodiments.

Detailed description of the invention

Fig. 1 illustrates that this hair laser photocoagulator mainly comprises following components: laser generator 01, gauge tap 08, laser guiding fibers 02, illuminated light guide fiber optics 03, handle 04, power line 09, attaching plug 10.Laser generator 01 connects attaching plug 10 by power line 09, in order to obtain electric energy.Gauge tap 08 connects laser generator 01 by wire 07, can control the generation of laser.Laser guiding fibers 02 is connected laser generator 01 with the tail end of illuminated light guide fiber optics 03, and front portion is passed in handle 04.The leading portion 05 of laser guiding fibers 02 exceeds 1mm ~ 10mm compared with leading portion 06 length of illuminated light guide fiber optics 03.The leading portion cover of laser guiding fibers 02 and illuminated light guide fiber optics 03 has protective sleeve 11, can extend the service life of laser guiding fibers 02 and illuminated light guide fiber optics 03.Protective sleeve 11 leading portion has opening, and the opening of the front end self-insurance sheath 11 of laser guiding fibers 02 and illuminated light guide fiber optics 03 stretches out.

Fig. 3 a-c illustrates the sectional view of the front end of laser guiding fibers 02 alternate embodiments.The cross section of laser guiding fibers 02 and protective sleeve 11 front end can be circular (as Fig. 3 a); or crescent (as Fig. 3 b); also can be have the optical fibers leading portion 05 that one or a few cross section is circle in meniscate protective sleeve 11, can certainly be other shape of conveniently thrusting Eyelash follicle.

Laser generator 01 can launch pulse and multi-pulse laser, and the pulsewidth of laser and energy can need to carry out free adjustment according to difference.Laser generator 01 can produce continuous print illuminating ray simultaneously.

In use procedure, the continuous print illuminating ray that laser generator 01 produces, through illuminated light guide fiber optics 03, optical fibers leading portion 06, irradiates working region, facilitates positioning action.The front end of optical fibers leading portion 05 is thrust bottom Eyelash follicle by operator, open gauge tap 08, laser pulse produces 01 by laser generator, optical fibers leading portion 05 is arrived by laser guiding fibers 02, act on the hair follicle of target eyelashes, accurate destruction is rich in melanic eyelashes root, and completed treatment operates.
