摘要 |
The invention relates to medicine, more specifically to ophthalmic surgery, and represents device, intended as for expansion pupil at insufficient mydriasis, and for support of capsular sac in the area of capsulorhexis in lens subluxation cases due to slightly STI ligamentous apparatus.Purpose of the utility model - modify structure irido - capsular retractor to facilitating handling structures on eye, not complicating the structure itself.Effect - new structure is simple in manufacturing and makes it possible to shift keying irido - capsular retractor, including rotary, reliably, atraumatic, thereby ensuring fast and removal of retractor.The technical result can be obtained, if irido - capsular retractor, containing handle with lock, installed with possibility of back - translational motion along the handle, and working part in the form of a hook, the handle extends at an angle 150 - 152?in working part length 2.2 - 2.4 mm, which then is bent at an angle of 25 - 26?and has length 2.5 - 2.7 mm, the retractor consists of double polyamide fishing line, both ends of which in proximal zone soldered, according to utility model its handle, its proximal end soldered, is led in silicon tube, length of which 10 mm, depth of 5 mm, the is led in interference, and in opposite end silicon tube also in interference depth of 4 - 5 mm, its distal end led straight cannula. |
