我院于1988年8月研制成功“YSZ-1型眼科手术注吸仪”,经动物实验(20只兔眼)获得成功。于9月用于临床,行白内障囊外手术和后房型人工晶体植入74例81只眼,获得满意效果。仪器的设计“YSZ-1型眼科手术注吸仪”由注吸器、负压源、负压瓶、负压调节阀(手控、脚控)和气阀转换等主要部件组成。该机注吸器由注吸头和水流调节阀组成;注吸器经硅胶吸管与负压瓶连通;负压瓶又通过另一管道分别与负压调节阀、气阀转换、负压源沟通。当负压源工作时,负压瓶产生压力,
Our hospital in August 1988 successfully developed “YSZ-1-type ophthalmic surgery suction device”, the animal experiments (20 rabbit eyes) to be successful. In September for clinical, extracapsular cataract surgery and posterior chamber intraocular lens implantation in 81 cases of 81 eyes, with satisfactory results. Instrument design “YSZ-1 eye surgery suction device” consists of the main components of the suction device, negative pressure source, negative pressure bottle, negative pressure regulating valve (manual, foot control) and valve conversion. The suction device is composed of a suction nozzle and a water flow control valve; the suction nozzle is communicated with the negative pressure bottle through a silica gel suction pipe; and the negative pressure bottle communicates with the negative pressure control valve, the air valve and the negative pressure source separately through another pipe. When negative pressure source work, negative pressure bottle pressure,
