内眼手术中,常常需要切除病变组织或处理玻璃体脱出等,玻璃体切除器是满足这一需要的良好设备,但因造价昂贵,大多数医院尚不具备,或因准备、消毒繁琐,难解燃眉之急。我们据此研制出一种最简易的手动后退式晶体玻璃体切割器。(一)设计与制作1.外套管:取16号针头,长约37mm,外径1.6mm,内径1.3mm。尖端稍磨钝,保留斜面长2mm,并将斜面磨锐,使管内径面成刀刃样。针管背面 Intraocular surgery, often require the removal of diseased tissue or treatment of vitreous prolapse, vitrectomy is to meet this need for good equipment, but because of the high cost, most hospitals still do not have, or due to preparation, disinfection cumbersome, difficult to meet the urgent needs . We developed one of the most simple hand-back crystal vitreous cutter. (A) Design and Production 1. Outer tube: take 16 needles, length 37mm, diameter 1.6mm, diameter 1.3mm. Slightly blunt tip, retaining the bevel length 2mm, and bevel sharpening, so that the inner diameter of the blade into a blade-like. Needle back
