在闭合式玻璃状体切除术中,常因巩膜切口部位的损伤或切口部位的漏水造成并发症,为此我们设计制作了带有注水系统的切口套管。由套管,注水管和管塞三部分组成。其长度略大于眼球壁的厚度,以不致影响器械在眼内的活动度。根据进入眼内器械的大小可制作不同口径的套管,术中选用,将其固定在巩膜切口上,器械沿套管进入眼内,注水管连接灌注管以维持眼内压,若行另外操作暂时不用此切口时可塞好管塞。经动物实验和临床试用证明,此
In the closed vitrectomy, often due to scleral incision site injury or incision site leakage complications, we have designed a cut with a water cannula system. By the casing, water pipes and pipe plugs three parts. Its length is slightly larger than the thickness of the eye wall so as not to affect the mobility of the instrument in the eye. According to the size of the instrument into the eye can produce different caliber cannula, surgery selected, fixed in the scleral incision, the device along the cannula into the eye, infusion tube connected to the perfusion tube to maintain intraocular pressure, if the line of operation Temporarily do not have this cut can be plug plug. Animal experiments and clinical trials proved that this
