Abstract
The utility model provides a device for automatic monitoring and adjusting energy of a quasi-molecule laser therapeutic device. The device for automatic monitoring and adjusting energy of a quasi-molecule laser therapeutic device is composed of an energy converter, an attenuator, and a controller. The energy converter 2 is a heat/electricity converting device. The attenuator 1 is formed from that an attenuation eyeglass is installed on a stepping motor. A control box 3 is that a signal preprocessor, a mould/digital converter (A/D), a microprocessor system are connected and installed on the same printed circuit board by a printed line to be placed in the control box. An LED display is installed on a panel of the control box. The device for automatic monitoring and adjusting energy of a quasi-molecule laser therapeutic device is adopted to be matched with a 'Compak-200 shape' quasi-molecule laser therapeutic device to be used for the operation of correcting cornea ametropia, operation energy can be automatically and stably adjusted within a desired range in the process of whole operation, and the operation energy is displayed in a real-time mode.
Description
This utility model relates to a kind of armarium, especially a kind of automatic monitoring of excimer laser machine energy and adjusting device that is used to proofread and correct the operation of cornea ametropia.
Be used to proofread and correct the cornea ametropia at present and perform the operation reasonable therapeutic equipments by U.S. Laser-Sight company manufacturing " Compak-200 type " excimer laser machine (PRK), the large hospital that China's condition is good is all introduced this instrument.This machine mainly partly is made up of computer, laser instrument, controller and optical path etc. four.Wherein, laser instrument is to be the gas laser of working media with the argon fluoride; Optical path is made up of decay eyeglass, focusing lens, X-axis and Y-axis scan mirror, 45 degree reflecting optics etc.; Controller is the unlatching and the scanning mode that stops and forming the X-axis and the Y-axis scan mirror of needed operative region and surgical effect by computer software control laser instrument.
Its work process is: the laser by computer-controlled laser instrument sends, through the attenuator decay, arrive X-axis and Y-axis scan mirror through lens focus, after the miter angle refracting telescope is refracted to predetermined operative site with required laser beam earlier again.Because what this machine used is the argon fluoride gas laser, the laser energy of its output has unstability to a certain degree, so former machine has adopted manual adjustment method to monitor and regulate the operation energy.Mainly there are following two deficiencies in this method:
1, in the operation process, the operation energy can't be monitored
Former machine monitoring operation energy just before art additional laser energy meter directly measure being equivalent to operative site, then can't implement after the operation beginning.
2, can not regulate in real time the variation of operation energy in the operation process
The method of regulating the operation energy in the former machine is: but control a small machine that the bidirectional movement of decay eyeglass is housed with a double-throw hand switch, before art, cooperate the additional-energy meter, situation of change according to the operation energy manually increases and decreases adjusting, and this adjusting can't be implemented in the art equally.
The purpose of this utility model provides a kind of auto-real-time monitoring of surgical laser energy and the quasi-molecule therapeutic instrument energy regulated in real time monitoring and adjusting device automatically can realize that Compak-200 type " PRK " therapeutic instrument normally moves the time.
This utility model mainly partly is made up of transducer, attenuator and control box three.Transducer is one heat/electric transducer, and attenuator is made up of step motor drive decay eyeglass, and control box then is made up of signal preprocessor, A/D converter (A/D), microprocessor system and light-emitting diode display etc.Transducer and attenuator are connected in the input port and the delivery outlet of control box respectively with lead.Its work process is: attenuator converts detected laser signal to the signal of telecommunication and inputs to control box, after control circuit is handled, control signal is exported to the operation energy of attenuator with stabilized lasers.
Adopt this device to cooperate " Compak-200 type " excimer laser machine to be used to proofread and correct the operation of cornea ametropia, can make in the whole surgery process, but operation energy automatic stabilisation be adjusted in the desired scope, and show in real time.
Below in conjunction with accompanying drawing this utility model is described in further detail.
Fig. 1 is that this utility model shows structural representation outward.
Fig. 2 is this utility model electrical equipment block diagram.
Fig. 3 is this utility model electrical schematic.
This utility model mainly is made up of transducer 2, attenuator 1 and control box 3.Transducer and attenuator are connected in the input port and the delivery outlet of control box respectively with lead, transducer is one heat/power conversion device; Attenuator is made up of step motor drive decay eyeglass face; Control box is made up of signal preprocessor, A/D converter (A/D), microprocessor system, light-emitting diode display etc.Wherein signal preprocessor is an integrated transporting discharging chip; A/D converter is one mould/number conversion integrated chip; Light-emitting diode display is made up of four eight sections charactrons; Microprocessor system is made up of microprocessor (MPU) chip, program storage (ROM) chip, parallel expansion mouthful (I/O) chip, address latch (AR) chip etc.Above device all is installed in except that light-emitting diode display on the same printed circuit board, and the panel that light-emitting diode display then is installed in control box allows.The signal of telecommunication that transducer converts to is connected to the preprocessor input through the control box input port with lead, the preprocessor outfan is connected to the input of A/D converter through printed circuit board (PCB), the outfan of A/D converter divides two-way to handle: the one tunnel links to each other with light-emitting diode display through lead, another road links to each other with the microprocessor input port through printed circuit board (PCB), the output end of microprocessor mouth through printed circuit board (PCB) respectively with the address latch input, parallel expansion mouthful input, the data input pin of program storage links to each other, and the outfan of address latch links to each other with the address port of program storage through circuit board, and the outfan of parallel expansion mouth links to each other with the delivery outlet of control box through lead.
