摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, particularly to ophthalmic surgery and concerns intraoperative intraocular pressure regulation (IPR). That is ensured by using a microsurgical system comprising a surgical cartridge, a surgical unit and a computer. The cartridge comprises an infusion chamber containing an irrigation fluid. The pressure is generated and maintained in the microsurgical system by a pressure generator hydraulically connected to the above surgical cartridge and comprising a compressed gas source. The device also comprises an electromagnetic proportional valve and a gas line hydraulically connecting the compressed gas source, proportional valve and surgical cartridge. The surgical unit gets hydraulically connected to the surgical cartridge by an infusion fluid line. The required IPR is specified. The pressure is maintained in the above infusion chamber by gas pressure-fed from the above compressed gas source into the surgical cartridge. The irrigation fluid is supplied into the surgical unit in the infusion fluid line. The irrigation fluid flow is measured in the infusion fluid line a signal corresponding to the measured irrigation fluid flow is injected into the computer. The estimate IOP is calculated in the computer in response to the received signal. The computer is used to regulate compressed gas pressure by injecting the second signal from the computer onto the proportional valve to maintain the estimate IOP equal to the required IOP.EFFECT: method provides the IOP regulation, including the compensation function that reduces potential intraoperative hypotension and secondary complications.2 cl, 4 dwgИзобретение относится к медицине, в частности к офтальмологической хирургии, и касается регулирования внутриглазного давления (ВГД) в процессе операции.
