Description
This utility model relates to a kind of anterior segment image analytical equipment, especially a kind of micro-anterior segment image analyser of scan-type slit lamp that is used for the clinical ophthalmology diagnosis.
The anterior segment image analyser, especially the micro-anterior segment image analyser of slit lamp is can be for the general clinical diagnosis of ophthalmology, also can gather, analyze and file the image of anterior ocular segment (cornea, iris, crystalline lens etc.), for the critical medical devices of clinical ophthalmology diagnosis, the consultation of doctors, teaching, scientific research, it is made up of slit lamp microscope, image pick-up device, image acquisition APU.But existing slit lamp microscope is not established scanning driving device, therefore can not carry out the scan-type dynamic acquisition, influences the result of use of the micro-anterior segment image analyser of slit lamp.
The purpose of this utility model is to provide a kind of and can also can gathers, analyze and file for the general clinical diagnosis of ophthalmology to the image of anterior ocular segment (cornea, iris, crystalline lens etc.); Both can carry out static plane to anterior segment image takes, also can carry out scan-type slit lamp anterior segment image static state and dynamic acquisition, obtain cornea, anterior chamber and lenticular anterior segment image, with the micro-anterior segment image analyser of the scan-type slit lamp that obtains the anterior ocular segment physiological parameter.
This utility model is provided with slit lamp microscope, image pick-up device, image acquisition APU.Image pick-up device connects microscope, and the output map interlinking of image pick-up device is as the collection analysis blood processor.Said slit lamp microscope is made up of slit lamp, slit lamp scanning driving device and microscope.The slit lamp scanning driving device is provided with motor, motor drum in-phase, crack arm synchronizing wheel, synchronous band, circuit for controlling motor and motor fixing frame.Motor is fixed on the motor fixing frame, and motor drum in-phase is fixed on the step motor shaft, and with band transmission synchronously, the Electric Machine Control line connects circuit for controlling motor between motor drum in-phase and the crack arm synchronizing wheel.
Said motor adopts three/four phase step motor, it is converted to angular displacement with electric impulse signal, come the pilot angle displacement by the control impuls number, thereby reach the purpose of accurate control slit lamp around axle rotational positioning in-10 ° to-170 ° angular range.That is to say that control signal can be sent by computer, producing step-by-step impulse control step motor through circuit for controlling motor rotates, rotate synchronously through the crack of band drive synchronously arm again, the signal controlling that its velocity of rotation, angle are sent by computer realizes slit lamp scanning and the synchronous purpose of anterior segment image dynamic acquisition.Therefore under driving of the present utility model, the micro-anterior segment image analyser of scan-type slit lamp can carry out static plane to anterior segment image and take, also can carry out the scan-type dynamic acquisition, obtain cornea, anterior chamber and lenticular anterior segment image, and carry out graphical analysis by computer and special-purpose software, calculate the clinician and carry out the various physiological parameters of anterior ocular segment such as the required corneal thickness of refractive surgery, corneal curvature, anterior chamber depth, angle of anterior chamber size.Analytical equipment is compared, under the driving of slit lamp scanning driving device, the micro-anterior segment image analyser of scan-type slit lamp can carry out static plane to anterior segment image and take, also can carry out the scan-type dynamic acquisition, obtain cornea, anterior chamber and lenticular anterior segment image, and carry out graphical analysis by computer and special-purpose software, calculate the clinician and carry out the various physiological parameters of anterior ocular segment such as the required corneal thickness of refractive surgery, corneal curvature, anterior chamber depth, angle of anterior chamber size.
