Description
I Изобретение относитс к медицине, а ;именно к офтальмологии, и может быть использовано дл вскрыти передней капсулы хрусталика.I The invention relates to medicine, namely, ophthalmology, and can be used to open the anterior lens capsule.
Цель изобретени - сокращение времени проведени операции и уменьшение травматизации тканей глаза.The purpose of the invention is to reduce the time of the operation and reduce the trauma of eye tissue.
На чертеже схематически изображено предлагаемое устройство, общий вид.The drawing schematically shows the proposed device, a General view.
Устройство содержит державку 1, стер- Ыень 2, режущий элемент 3, присгюсобле- дл поворота режущего элемента, вклю- Йающее магнит 4, выполненный кольцевым и установленный с возможностью вращени р плоскости, параллельной оси державки 1, Магнит 5, выполненный в виде части эллип- фоида вращени , также установленный с воз- 1ИОЖНОСТЫО вращени в плоскости, па- ||)аллельной оси державки и закрепленный (|а конце державки 1, причем на рабочей 1|асти магнита 5 выполнена выемка 6 с 1|ривизной, соответствующей кривизне перед- Йей капсулы хрусталика. Режущий элемент 3 установлен на периферической части магнитна 5, а полюса магнита 4 расположены над рНазноименными полюсами магнита 5. Ось в ращени магнита 4 совпадает с осью вра- Ц1ени магнита 5 и оптической осью объектива 7 операционного микроскопа. Выпол- магнита 5 в виде части эллинсои- д|а вращени обусловлено тем, что вследствие обтекаемости этой формы снимаетс травма заднего эпители 8 роговицы глаза. Магнит 4, размещенный над рабочим концом стержн 2, может быть закреплен на объективе 7 операционного микроскопа. Оси вращени магнитов 4 и 5 могут совпадать и в этом случае достигаетс максималь0The device contains a holder 1, an eraser 2, a cutting element 3, which is attached to rotate the cutting element, including a magnet 4, made annular and mounted with the possibility of rotation of a plane with a plane parallel to the axis of the holder 1, Magnet 5, an ellipse shaped as a part - rotational feed, also installed with the possibility of rotation in the plane, pa- ||) of the allele axis of the holder and fixed (| at the end of the holder 1, and the working 1 | part of the magnet 5 has a notch 6 with 1 с curvature corresponding to the curvature before - Yeah lens capsule. Cutting ale Ment 3 is mounted on the peripheral part of the magnetic 5, and the poles of the magnet 4 are located above the poles of the magnet 5. The axis in the growth of magnet 4 coincides with the axis of rotation of the magnet 5 and the optical axis of the objective 7 of the operating microscope. The d rotation is due to the fact that the trauma of the posterior epithelium 8 of the cornea is removed due to the flow around this form. The magnet 4 placed above the working end of the rod 2 can be attached to the objective 7 of the surgical microscope. The axis of rotation of the magnets 4 and 5 may coincide and in this case the maximum is reached.
ное взаимодействие магнитов (наибольшее режущее усилие), которое .можно регулировать путе.м изменени рассто ни между магнитами.interaction of the magnets (the greatest cutting force), which can be controlled by changing the distance between the magnets.
Устройство работает следующим образом. После вскрыти передней камеры рабочий конец стержн 2 с закрепленным на нем магнитом 5 ввод т в переднюю камеру таким образом, что продольна ось стержн 2 и ось вращени магнита 5 параллельны радужной оболочке. Затем рабочую часть стержн 2 подвод т к передней капсуле хрусталика и выемку 6 магнита 5 совмещают с хрусталиком 9. Таким образом плоскость ножа режуцдего элемента 3, на5 пример алмазного, устанавливают перпендикул рно передней капсуле хрусталика. Магнит 4 подвод т и устанавливают вне полости глаза над рабочим концом стержн 2 на рассто нии от него, необходимом дл обеспечени достаточного усили резани .The device works as follows. After opening the anterior chamber, the working end of the rod 2 with the magnet 5 fixed on it is inserted into the anterior chamber in such a way that the longitudinal axis of the rod 2 and the axis of rotation of the magnet 5 are parallel to the iris. Then, the working part of the rod 2 is brought to the anterior capsule of the lens and the notch 6 of the magnet 5 is aligned with the lens 9. Thus, the plane of the knife of the cutting element 3, 5 an example of diamond, is set perpendicular to the anterior capsule of the lens. Magnet 4 is brought in and installed outside the eye cavity above the working end of the rod 2 at a distance from it, which is necessary to ensure a sufficient cutting force.
0 После этого магнит 4 вращают в плоскости, расположенной параллельно оси державки. Вращение магнита 4 осуществл ют, поворачива его вручную или привод в движение электродвигателем (не показан). Под дейст5 вием магнитного пол магнит 5 начинает поворачиватьс вместе с режущим элементом 3 вокруг своей оси вращени , при этом производ т круговой разрез передней капсулы хрусталика.0 After that, the magnet 4 is rotated in a plane parallel to the axis of the holder. The rotation of the magnet 4 is performed by turning it manually or driven by an electric motor (not shown). Under the action of the magnetic field, the magnet 5 begins to rotate with the cutting element 3 around its axis of rotation, and a circular incision is made in the anterior lens capsule.
Уменьшение травматизации тканей гла0 за достигаетс путем введени в полость глаза миниатюрного манипул тора (рабочий конец стержн с магнитом), а вращение его осуществл ют при помощи магнита, расположенного вне глаза. Врем проведени операции сокращаетс на 55%, травматич- ность - на 45%.The reduction of tissue trauma to the head is achieved by inserting a miniature manipulator into the eye cavity (the working end of the rod with a magnet), and its rotation is carried out using a magnet located outside the eye. The operation time is reduced by 55%, the injury rate is reduced by 45%.
