The dominant mechanism of ultrasonic handpiece affected part state recognition system is different tissues to the resistance difference of ultrasonic signal clearly, and obvious for normal cataract tissue emulsifying effectiveness, for non-cataract tissue, the emulsifying effect is very weak, embodies the selectivity of ultrasonic emulsification; In addition, under the ultrasound condition of equal-wattage, the impedance of the cataract tissue performance that hardness is different also has than big difference, according to the concrete level of impedance value, can judge the hardness rank of current cataract kernel tissue, and the ultrasonic power of taking to be fit to is realized emulsifying.
Two kinds of recognition systems combine, and the hardness rank of cataract kernel is judged that the result is more reliable.
(3) adopt the vacuum flow amount control system, the clogged with fragments suction channel that after the cataract stone is organized emulsifying in the eyeball in the operation, produces, after negative pressure raises and absorbs this fragment of tissue, vacuum control system makes zero negative pressure moment by a pressure relief opening, prevents to cause the phenomenon of subsiding because of utmost point low discharge high negative pressure causes the anterior chamber to be sucked.
In the cataract operation, most important two indexs are to attract negative pressure with irrigation flow except ultrasonication, attract negative pressure to be used for the cataract tissue fragment after the emulsifying is aspirated out pipeline, irrigation flow is used to keep the intraocular pressure balance, in the whole surgery process, the balance of keeping groundwater increment and aspiration is the core purpose of intelligent ophthalmology emulsification instrument vacuum flow amount control system.
(4) adopt energy management system; organize rank, position and state to regulate the output size and the pattern of emulsifying ultrasonic energy automatically according to optical identification and the determined cataract stone of affected part status system; perform the operation in real time effectively, other tissue of protection ophthalmic is without prejudice.
Traditional cataract emulsifying operation adopts continuous ultrasound that the cataract kernel is carried out emulsifying, and operating time is long, intra-ocular ultrasound energy accumulation effect can cause necessarily surrounding tissue and burn, and ultrasonic handpiece continuous operation is simultaneously generated heat easily; For avoiding above-mentioned defective, the ultrasonic release mode of emulsifying is improved, take pulsating ultrasound to carry out emulsifying, fully cooled off at the intermission of pulse ultrasonic transducer, promote the performance that works long hours of ultrasonic transducer, obtain the second best in quality power ultrasonic signal, obtain better ultrasonic emulsification effect.In the actual test, the ultrasonic output signal of emulsifying is during pulse release, and signal quality maintains very high level.Simultaneously, the intermittence of the ultrasonic signal of pulsed discharges the damage help to reduce in the intraocular surgery normal structure,
In conjunction with clinical use-case, according to the hardness rank of cataract kernel, in the operation of intelligent ophthalmology emulsification instrument under the normal conditions emulsive power ultrasonic energy take lower numerical value, to reduce intraocular damage as far as possible, can guarantee surgical effect again simultaneously.If underpower, emulsifying fails to finish, and the doctor to finish emulsification procedure, is greatly alleviated doctor's working strength by control backpedalling brake depth compensation ultrasonic energy, guarantees the safe and efficient of operation.
