Abstract

Изобретение относитс  к офтальмологическим инструментам, позвол ет уменьшить травматичность операции и предупредить послеоперационные осложнени  за счет того, что игла 1 выполнена в виде двух, равных по длине, сегментов сопр женных окружностей разного радиуса и снабжена руко ткой 5. При этом отношение радиуса со стороны тупого конца иглы к радиусу со стороны острого выбираетс  в интервале 0,7 - 0,9. Кроме того, фиксатор дл  нити выполнен в виде отверсти  4 у острого конца иглы. 2 з.п. ф, 2 ил.The invention relates to ophthalmic instruments, reduces the invasiveness of the operation and prevents postoperative complications due to the fact that needle 1 is made in the form of two equal length segments of adjacent circles of different radius and is provided with a handle 5. In this case, the ratio of the radius is from the blunt side. the end of the needle to the radius on the acute side is chosen in the range of 0.7 - 0.9. In addition, the lock for the thread is made in the form of a hole 4 at the sharp end of the needle. 2 hp f, 2 Il.

Description

Изобретение относится к медицинским офтальмологическим инструментам и может быть использовано для хирургической коррекции гиперметропии, в том числе и афакии.The invention relates to medical ophthalmic instruments and can be used for surgical correction of hyperopia, including aphakia.

Цель изобретения — уменьшение травматичности операции и предупреждение послеоперационных осложнений.The purpose of the invention is to reduce the morbidity of the operation and the prevention of postoperative complications.

На фиг. 1 представлено устройство, общий вид; на фиг. 2 — то же, вид сбоку.In FIG. 1 shows a device, a General view; in FIG. 2 is the same side view.

Устройство состоит из иглы 1 с режущими гранями 2 и 3, фиксатора для нити Зв виде отверстия 4, рукоятки 5. При этом одна половина иглы 6 имеет меньший радиус кривизны Ri, а другая половина иглы 7 — больший радиус кривизны R2. При этом отношение R2 и Ri выбирается в интервале 0,7—0,9. Кроме того, режущие грани иглы расположены в плоскости изгиба.The device consists of a needle 1 with cutting edges 2 and 3, a retainer for thread Sv in the form of an opening 4, a handle 5. In this case, one half of the needle 6 has a smaller radius of curvature Ri, and the other half of the needle 7 has a larger radius of curvature R2. In this case, the ratio of R2 and Ri is selected in the range of 0.7-0.9. In addition, the cutting edges of the needle are located in the plane of the bend.

Устройство работает следующим образом.The device operates as follows.

После акинезии, отступив от лимба 2,5— 3 мм, делают надрез роговицы на глубину 0,2—0,3 мм на 6 и 12 ч. Изогнутой Иглой с предварительно заправленной супраМидной нитью производят полуокружность от 12 до 6 ч. После выкола острия иглы йить освобождают из отверстия на конце иглы, а саму иглу 1 выводят из роговицы по обратному пути от 6 до 12 ч. Запра вив конец нити в отверстие на конце иглы, делают аналогичным образом полуокружность от 6 до 12 ч с выколом иглы на 12 ч. Конец нити освобождают, иглу выводят 5 по обратному пути от 12 до 6 ч. Концы супрамидной нити затягивают на 12 ч, узел погружают в слои роговицы (при необходимости делают парацентез роговицы).After akinesia, stepping back from the limb 2.5-3 mm, make an incision of the cornea to a depth of 0.2-0.3 mm for 6 and 12 hours. A semicircle from 12 to 6 hours is produced with a curved needle with a previously threaded supraMid thread. After the tip is punctured the yarn needles are released from the hole at the end of the needle, and the needle 1 itself is removed from the cornea on the return path from 6 to 12 hours. By closing the end of the thread into the hole at the end of the needle, a semicircle is made in the same way from 6 to 12 hours with the needle punched out for 12 hours The end of the thread is released, the needle is brought out 5 along the return path from 12 to 6 hours. The ends of the supramide thread tighten After 12 hours, the node is immersed in the layers of the cornea (if necessary, paracentesis of the cornea is done).
