The specific embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is described in further detail:

Pharyngotympanic tube laser therapy aparatus shown in the figure mainly is made up of laser generator 1, fiber coupler 2, optical fibers 3 and 4 four parts of laser fiber inducer.Laser generator 1 is divided into optics and power supply part two parts again: optics comprises the completely reflecting mirror 5 that is installed in successively on the optical bench 13 and laser pump cavity 7, partially reflecting mirror 10 and the support 11 thereof of support 6, built-in pump Pu lamp 8 and laser crystal 9 thereof; Power supply part comprises power supply 15 and lead 14, and power supply 15 links to each other with pumping lamp 8 by conductor wire 14.Fiber coupler 2 comprises focus lamp 12 and a support and a fiber-optical socket, and fiber coupler 2 also is installed on the above-mentioned optical bench 13, is positioned at a side of partially reflecting mirror 10.Above-mentioned completely reflecting mirror 5, laser crystal 9, partially reflecting mirror 10 and focus lamp 12 are positioned on the same optical axis.One end of optical fibers 3 is plugged on the fiber-optical socket of fiber coupler 2, and its end face center overlaps with the focus point of focus lamp 12, can guarantee that laser enters optical fibers and is transmitted to its other end ejaculation, and the other end of optical fibers 3 is inserted in the laser fiber inducer 4.

Laser fiber inducer 4 is the important composition parts that optical fibers 3 imported to pharyngotympanic tube obstruction place, it can have two kinds of versions: a kind of structure is that it is made of the guide wire 17 with arc-shaped bend head, optical fibers 3 is inserted into wherein from the afterbody of guide wire 17, and can pass from the arc-shaped bend head of guide wire 17, the arc-shaped bend head of guide wire 17 can be arranged on by the eustachian orifice easily, can insert in the pharyngotympanic tube smoothly to guarantee optical fibers 3.This structure of laser fiber inducer 4 is single, practical, reliable.Another kind of structure is that it is made of the guide wire 17 with arc-shaped bend head, three-way diverter valve 18, injecting liquid drug termination 19 and optical fiber insertion termination 20, the interface that optical fiber inserts termination 20 and three-way diverter valve 18 is connected as a single entity, the afterbody of guide wire 17 adopts seal nipple to link to each other with another interface of three-way diverter valve 18, and injecting liquid drug termination 19 is hose connection with the 3rd interface employing of three-way diverter valve 18.The effect of three-way diverter valve 18 is to make optical fiber importing and medicinal liquid inject two kinds of functions to change mutually: when optical fiber imports, optical fibers 3 inserts termination 20 by optical fiber and inserts, enter guide wire 17 through three-way diverter valve 18, injecting liquid drug termination 19 is in sealed state at this moment; During liquid medicine injection, medicinal liquid injects three-way diverter valve 18 by injecting liquid drug termination 19 through flexible pipe, enters guide wire 17 again, and this moment, optical fiber insertion termination 20 was in sealed state, to guarantee that medicinal liquid enters guide wire 17 smoothly.This structure of laser fiber inducer 4 can further be made Drug therapy to it after laser is got through pharyngotympanic tube, to reach more perfect therapeutic effect.

In addition, above-mentioned laser generator 1 and fiber coupler 2 are installed in the cabinet 16 jointly, in the cabinet 16 also routinely device the auxiliary such as cooling, protection system of laser generator 1 is arranged.

The work process of above-mentioned pharyngotympanic tube laser therapy aparatus is such: connect civil power, pumping lamp 8 sends filtering ultraviolet in laser pump cavity 7 inside, filtering ultraviolet converges on the laser crystal 9 through laser pump cavity 7, excitation laser crystal 9 produces the photon of specific wavelength, this photon moves along laser crystal 9 axis directions, and vibrate back and forth, constantly amplify, rise in value, and transmit laser beam by partially reflecting mirror 10 through the resonator cavity formed by laser crystal 9, completely reflecting mirror 5 and partially reflecting mirror 10.After the focus lamp 12 of laser beam in fiber coupler 2 focuses on, the spot diameter of its focus place laser beam is less than the end face diameter of optical fibers 3, because the end face center of optical fibers 3 overlaps with the focus of focus lamp 12, this laser beam can be coupled into optical fibers 3 effectively, and the transmission back is penetrated from the other end within it.The other end of optical fibers 3 inserts termination 20 by optical fiber and enters laser fiber inducer 4, the spool of swivel tee switching valve 18 before inserting, make optical fiber insert that termination 20 is in conducting, injecting liquid drug termination 19 is in closed state, optical fibers 3 enters pharyngotympanic tube through three-way diverter valve 18 and guide wire 17, touch the obstruction place until fiber end face, can adopt the laser of design power to treat.The powerful luminous energy that laser had is with the vaporization of the tamper in the pharyngotympanic tube, and along with progressively going deep into of optical fibers 3, tamper is vaporized one by one, and pharyngotympanic tube has also just all been got through.And then carry out the medicinal liquid auxiliary treatment, earlier optical fibers 3 is extracted out, then with the spool half-twist of three-way diverter valve 18, make 19 conductings of medicinal liquid dispensing end head, optical fiber inserts termination 20 sealings, with syringe by injecting liquid drug termination 19 injecting liquid drug in guide wire 17, again in pharyngotympanic tube.The importing of above-mentioned optical fibers 3 and therapeutic process are assisted to finish by the nasal cavity sight glass simultaneously.

Though this utility model has adopted advanced laser technology treatment pharyngotympanic tube, also has certain deficiency.Show that mainly the light energy that pumping lamp sends only has sub-fraction to be converted into the laser energy of laser crystal, add the system loss of power supply itself, the electrical efficiency of this therapy apparatus has only about 3%, and this is ubiquitous phenomenon by the decision of laser instrument self character.This phenomenon is that most of luminous energy of pumping lamp will become heat energy and the temperature of pumping lamp, laser crystal, laser pump cavity is sharply raise thereupon the problem of bringing.In order to make optics energy operate as normal, this therapy apparatus need be equipped cooling system, so that temperature remains in the scope of permissible value.The equipment cooling system makes complete machine become heavy undoubtedly.However, because laser beam is got through salpingian time weak point, only need several seconds to tens seconds, operation back wound healing is also fast, and cure rate is high, so total power consumption is still lower, therapeutic efficiency has improved manyfold than additive method and apparatus, greatly reduces the treatment cost.

Simultaneously, the optical fibers diameter that this utility model adopted is little, elongated, pliability is good, and this makes sends to intravital, several times crooked depths, pharyngotympanic tube road, dark Tibetan to laser and become possibility.Laser is vaporized to tamper and when getting through, and is little to the health tissues damage in the process because laser alignment is strong, and laser has hemostatic function again, is aided with Drug therapy after the operation, and pharyngotympanic tube road tissue repair is just very fast.In a word, the clinical practice experiment shows: this utility model operation process is quick, and the patient suffering is few, safety, and the cure rate height is that the treatment pharyngotympanic tube stops up the effective new way of disease.Social value that it is higher and economic worth will make this utility model obtain extensive promotion and application.
