Abstract

FIELD: medical equipment, in particular, instruments for ophthalmologic operations. SUBSTANCE: the cystotome for front capsulotomia uses a handle and a cone-shaped knife bent upwards with the cutting member on the end, sharpened on both sides, and the edge on the tip. The novelty in the cystotome is in the fact that the cutting member has an additional cutting element positioned on the external side of the knife tip bending. This additional cutting element is made in the form of a pyramid truncated from the base on the side of the edge at an angle of 30 deg., and the side located opposite the edge serves as the cutting edge. EFFECT: reduced traumatism of eye tissues due to the fact that for an effective operation on the front capsule of the eye crystalline lens only one puncture of the glass lens will suffice.

Цель изобретения - уменьшение травматизации тканей глаза за счет того, что для эффективного проведения операции на передней капсуле хрусталика глаза достаточно произвести всего один прокол линзы глаза. Цистотом для передней капсулотомии содержит ручку и изогнутый кверху конусообразный нож с режущей частью на конце, заточенной с обеих сторон и острием на кончике. Новым в цистотоме является то, что режущая часть имеет дополнительный режущий элемент, расположенный с наружной стороны изгиба кончика ножа. Этот дополнительный режущий элемент выполнен в форме пирамиды, усеченной от основания со стороны острия под углом 30°, а сторона, расположенная напротив острия, является режущей кромкой.The purpose of the invention is to reduce trauma to eye tissue due to the fact that for an effective operation on the anterior capsule of the lens of the eye, it is enough to make only one puncture of the eye lens. The cystotome for the anterior capsulotomy contains a handle and a cone-shaped knife curved upward with a cutting part at the end, sharpened on both sides and pointed at the tip. New in the cystotome is that the cutting part has an additional cutting element located on the outside of the bend of the tip of the knife. This additional cutting element is made in the form of a pyramid, truncated from the base from the side of the tip at an angle of 30 °, and the side located opposite the tip is the cutting edge.
