Abstract
The utility model relates to a laser path device for a quasi-molecular laser therapeutical instrument for ophthalmology, which comprises a laser (1), an attenuator (2), a focalizer (4), an X/ Y scanner (5) and an enoscope (6). A light shutter (8) is arranged between the attenuator (2) and the focalizer (4). The laser path device for a quasi-molecular laser therapeutical instrument for ophthalmology is characterized in that a light signal sampling device is arranged between the attenuator (2) and the light shutter (8); the electrical signal that is output by the laser detector (3) is jointed to the input opening of a controller (9). Because the rear part of the attenuator is provided with the light signal sampling device, the controller can monitor the intensity of light that is output by the attenuator in actual time. The rate of attenuation to the laser beam of the attenuator can be controlled by a master controller to make the intensity of light that is output by the enoscope lie in the suitable range.
Description
This utility model relates to a kind of medical laser treatment apparatus.
In the prior art, the excimer laser therapeutic instrument for ophthalmology is to utilize excimer laser beam (193 nanometer) that eye cornea is cut shaping, thereby reaches the therapeutic equipments of correction of refractive errors or excision aglia.Its light path part comprises the laser instrument that is used to launch laser beam, the attenuator that is arranged at the rear portion of described laser instrument and is used for the laser beam that described laser instrument is launched is decayed, the focalizer that is arranged at the rear portion of described attenuator and is used for the laser beam that described attenuator sends is converged, be arranged at the rear portion of described focalizer and be used for the light beam of described focalizer output is carried out the X/Y scanning device of directions X and Y scanning direction, be arranged at the enocscope at the rear portion of described X/Y scanning device, described X/Y scanning device with sweep the anchor driver and be connected, be provided with optical gate between described attenuator and the described focalizer.Wherein, the laser energy that arrives cornea from refracting plate is unusual important parameters for operation, regulate arrival cornea energy by adjusting attenuator at present, but behind the side energy, owing to other operation fails to begin immediately operation, the operation energy may depart from the energy when measuring, cause to cornea owe rectify or strong excessively.
The purpose of this utility model is to provide a kind of can carry out laser optical path device on the excimer laser therapeutic instrument for ophthalmology of real-time detection to the light energy that refracting plate penetrates.
The technical solution of the utility model is:, laser optical path device on a kind of excimer laser therapeutic instrument for ophthalmology, comprise the laser instrument that is used to launch laser beam, the attenuator that is arranged at the rear portion of described laser instrument and is used for the laser beam that described laser instrument is launched is decayed, the focalizer that is arranged at the rear portion of described attenuator and is used for the laser beam that described attenuator sends is converged, be arranged at the rear portion of described focalizer and be used for the light beam of described focalizer output is carried out the X/Y scanning device of directions X and Y scanning direction, be arranged at the enocscope at the rear portion of described X/Y scanning device, described X/Y scanning device with sweep the anchor driver and be connected, be provided with optical gate between described attenuator and the described focalizer, be provided with the optical signal sampling apparatus between described attenuator and the described optical gate, after described optical signal sampling apparatus converted optical signal to the signal of telecommunication through laser detector, the signal of telecommunication of described laser detector output was connected on the input port of described controller.
This utility model compared with prior art has following advantage:
Owing to be provided with the optical signal sampling apparatus at the rear portion of attenuator, therefore after its optical signal converts the signal of telecommunication to through laser detector, controller can monitor the light intensity of attenuator output in real time, and through can be converted into the light intensity of enocscope output after the computing, can control the dough softening to laser beam of attenuator by master controller, make the light intensity of enocscope output be within the suitable scope.
