Изобретение относитс к медицине, а имен- Но к офтальмологии, и может быть ис- Ьользовано при экстракции катаракты. Цель изобретени - снижение травма- тичности операции и повышение срока службы резектора. The invention relates to medicine, and specifically to ophthalmology, and can be used in cataract extraction. The purpose of the invention is to reduce the trauma of the operation and increase the service life of the resector.
На фиг. 1 представлен резектор, общий вид; на фиг. 2 - узел I на фиг. 1.FIG. 1 shows the resector, a general view; in fig. 2 — node I in FIG. one.
Резектор содержит руко тку 1, в котором размещен источник вакуума, выполненный в виде резиновой камеры 2 с пластинкой 3, :в занной с цилиндрической головкой 4 посредством трубочки 5. Головка состоит из эпорного цилиндра с глухим концом 6, режущего элемента 7, выполненного в виде ци- риндра с режущей кромкой 8, толщина ко- {горой 0,5-1,0 мкм. Режущий элемент вы- Ьолнен из неметаллического материала. Рассто ние между плоскост ми нижнего кра The cutter contains a handle 1 in which a vacuum source is placed, made in the form of a rubber chamber 2 with a plate 3: in a cylindrical head 4 with a tube 5. The head consists of an eporic cylinder with a blind end 6, a cutting element 7 made in the form a cylinder with a cutting edge 8, the thickness of the co- {mount 0.5-1.0 microns. The cutting element is made of non-metallic material. The distance between the planes of the bottom edge

пластину 3 резиновой камеры 2, устанавливает головку резектора на центральную часть капсулы хрусталика. Убедивщись в точности , оператор снимает палец с пластины , тем самым создава пониженное давление внутри головки, вследствие чего из-за разности давлени в камере и внутри глаза передн поверхность капсулы приподнимаетс и, прижима сь к режущей кромке 8 режущего элемента 7, отрываетс от основной части в виде диска, который прилипает к верхней части вакуумной камеры . Далее оператор убирает резектор от глаза.plate 3 of the rubber chamber 2, installs the head of the resector on the central part of the lens capsule. Making sure that the operator removes a finger from the plate, thereby creating a reduced pressure inside the head, as a result of which, due to the pressure difference in the chamber and inside the eye, the front surface of the capsule rises and, pressing against the cutting edge 8 of the cutting element 7, detaches from the main part in the form of a disk that sticks to the upper part of the vacuum chamber. Next, the operator removes the resector from the eye.
