(54J УСТРОЙСТВО ДЛЯ РАЗРУШЕНИЯ ВЕНОЗНЫХ КЛАПАНОВ(54J DEVICE FOR DESTRUCTION OF VENOUS VALVES
1one
Изобретение относитс к медицинской технике, а именно к медицинским инструментам , используемым в хиругии кровеносных сосудов.The invention relates to medical technology, namely to medical instruments used in blood vessel surgery.
Известен хирургический инструмент дл Known surgical instrument for
внутрисосудистых операций, содержащий руко тку, гайку, цанговый зажим и сменный стержень l3.intravascular operations containing a handle, a nut, a collet clamp, and a replaceable rod l3.
Известен разрушитель клапанов, содержащий две цилиндрические канюли, фиксированные на гибком тросе - направл ющую и разрушающую с крючкообразным выступом С2.A known valve destroyer comprising two cylindrical cannulas fixed on a flexible cable — a guide and a breaker with a hook-shaped protrusion C2.
Однако таким устройством нельз раз- руигить все лепестки клапанов, а такжеHowever, such a device could not unravel all the petals of the valves, as well as
возможно попадание крючка в боковые ветви вены и повреждение ее внутренней стенки в св зи с плотным прилеганием стенки вены к разрушающей канюле в месте крючкообразных выступов.the hook may hit the side branches of the vein and damage its inner wall due to the tight fit of the wall of the vein to the destructive cannula in the place of the hook projections.
Целью изобретени вл етс повышение надежности захвата и разрушение всех лепестков клапана, исключение повреждени внутренней стенки вены и попадание крючкообразных выступов в боковые ветвиThe aim of the invention is to improve the reliability of the grip and the destruction of all the petals of the valve, eliminating damage to the inner wall of the vein and hitting hook-shaped protrusions in the side branches
Достигаетс это тем, что разрушающа канюл имеет наклонные каналы и штуцер с осевым каналом, причем наклонные каналы соединены с осевым.This is achieved by the fact that the destructive cannula has inclined channels and a fitting with an axial channel, and the inclined channels are connected to the axial channel.
На чертеже изображено предлагаемое устройство дл разрушени венозных клапанов .The drawing shows the proposed device for the destruction of venous valves.
Устройство содержит направл ющую 3, разрушающую 2 канюли, фиксированные на гибком тросе 3, крючкообразные выcтупы 4, штуцер 5 с осевым каналом 6 и наклонные каналы 7 на разрушающей канюле.The device contains a guide 3, destroying 2 cannulas, fixed on flexible cable 3, hook-shaped protrusions 4, fitting 5 with an axial channel 6 and inclined channels 7 on a destroying cannula.
Устройство работает следующим образом .The device works as follows.
На штуцер 5 надевают эластичную трубку 8 и провод т устройство в вену 9 в ретроградном по отношению к клапанам 10 направлении. Через эластичную трубку 8, штуцер 5 и далее через наклонные каналы 7 производитс дозированное подведение жидкости, например физиологического раствора хлористого натри , между стенкой вены 9 и крючкообразными выступами 4. За счет движени жидкости лепестки клаAn elastic tube 8 is put on the fitting 5 and the device is led to the vein 9 in the direction retrograde to the valves 10. Through the elastic tube 8, fitting 5 and further through the inclined channels 7, a dosed supply of fluid, for example, physiological saline sodium chloride, is performed between the wall of the vein 9 and the hook-shaped projections 4. Due to the movement of the fluid, the petals of the
