Description

О О о 3 Фиг1 о Изобретение относитс  к медицинс кой технике и может быть использов но в сосудистой хирургии. Известен противоэмболический фильтр, содержащий шарнирно соедин ные элементы с фиксирующими зубцами Ги Недостатком известного фильтра  вл етс  раст жение вены по всей i окружности, что травматично. Кроме того, сетка фильтра  вл етс  массив ным преп тствием дл  кровотока и са ма способствует тромбообразованию на ее поверхности из-за неоднородности материала. Цель изобретени  - уменьшение травмировани  вены и предупреждение тромбоэмболии легочной артерии у больных с эмбологенными тромбозам вен нижних конечностей и нижней полой вены. Поставленна  цель достигаетс  тем, что в противоэмболическом филь ре, содержащем шарнирно соединенные элементы с фиксирукнцими зубцами, указанные элементы подпружинены и выполнены в виде Г-образно изогнуты перфорированных пластин. На фиг. 1 изображен фильтр, вид сверху; на фиг. 2 - то же; вид сбоку , на фиг. 3 - фильтр в развернуто положении; на фиг. 4 - фильтр в сло женном положении; на фиг. 5 - аппли катор дл  чрезвенного введенна  фильтра в нижнюю полую вену; на фиг. 6 - наконечник аппликатора с захватами; на фиг. 7 -фильтр с аппликатором . Фильтр содержит шарнирно соедине ные элементы 1 с фиксирующими зубцами 2. Элементы 1 вьшолнены в виде Г-образно изогнутых перфорированных пластин, соединены стержнем 3 с пружиной Д. Отогнута  часть 5 каждой пластины имеет клиновидную форму. Аппликатор состоит из корпуса 6 наконечника, ползунка 7 с шарнирно закрепленными к нему захватами 8, 81 штифта-упора 9, руко тки 10. Св зь между захватами 8 и руко ткой 10 осуществл етс  посредством эластичной металлической спирали-оболочки 11 с проход щим., внутри нее гибким тросом 12. Оболочка с одной стороны прикреплена к корпусу 6, с другой стороны - к руко тке 10, трос 12 своими концами соединен с папзунком 7 и поршнем 13. Перемеща  порщень в сторону захватов , обеспечивают перемещение троса в оболочке. При этом перемещаетс  ползунок 7 в корпусе 6, а захваты расход тсй относительно упора 9. Максимально разведенные захваты ввод т в крайние отверсти  фильтра со стороны пружины. Затем перемещают поршень .в. обратную сторону, трос с ползунком перемещаютс  относительно корпуса, захваты, продвига сь внутрь корпуса, смыкаютс  и сжимают фильтр за перемычки между отверсти ми. Привод поршн  может быть винтовым. Линейна  центровка фильтров обеспечиваетс  пр моугольной формой корпуса . Под рентгеновским контролем наконечник аппликатора с фильтром ввод т в нижнюю полую вену и в нужном ее участке устанавливают фильтр. Дл  этого с помощью поршн  перемещают трос с ползунком и захватами, которые, вьщвига сь из корпуса, размыкаютс  на необходимый дл  освобождени  от фильтра угол. Пластины фильтра под действием пружины расправл ютс  на 90-120 и зубцами фиксируютс  в стенке вены. После этого аппликатор вывод т из вены. Использование фильтра улучшает задерживающий противоэмболический эффект не только за счет щелевидной деформации вены, но и введени  в ее просвет пластинчатого фильтра с ототверсти ми , допускающими сохранение кровотока без риска прохождени  эмболов .About About About 3 FIG. 1 The invention relates to a medical technique and can be used in vascular surgery. A known anti-embolic filter containing hinge-connected elements with retaining teeth Gu. A disadvantage of the known filter is the stretching of the vein around the i circle, which is traumatic. In addition, the filter screen is a massive barrier to blood flow and itself contributes to thrombus formation on its surface due to the heterogeneity of the material. The purpose of the invention is to reduce trauma to the vein and prevent pulmonary embolism in patients with embologated venous thrombosis of the lower extremities and inferior vena cava. This goal is achieved by the fact that in an anti-embolism filter containing articulated elements with fixed teeth, these elements are spring-loaded and made in the form of L-shaped curved perforated plates. FIG. 1 shows a filter, top view; in fig. 2 - the same; side view, in FIG. 3 - filter in the unfolded position; in fig. 4 - filter in a folded position; in fig. 5 - applicator for an extra filter inserted into the inferior vena cava; in fig. 6 - applicator tip with grippers; in fig. 7-filter with applicator. The filter contains pivotally connected elements 1 with locking teeth 2. Elements 1 are made in the form of L-shaped bent perforated plates, connected by a rod 3 with a spring D. Part 5 of each plate has a wedge-shaped form. The applicator consists of a tip body 6, a slider 7 with hinges 8, 81 of a pin 9, a hinge 10 hinged to it, a handle 10. inside it, with a flexible cable 12. On one side, the sheath is attached to the housing 6, on the other hand, to the handle 10, the cable 12 is connected to the podzunk 7 and the piston 13 with its ends. This moves the slider 7 in the housing 6, and the grippers diverge relative to the stop 9. The most diluted grippers are inserted into the outer holes of the filter on the side of the spring. Then move the piston. the reverse side, the cable with the slider moves relative to the body, grips, moving inside the body, close and squeeze the filter behind the web between the holes. The piston drive may be screwed. Linear alignment of the filters is provided by a rectangular body shape. Under x-ray control, the tip of the filter applicator is inserted into the inferior vena cava and a filter is installed in the desired portion of the vein. To do this, with the help of a piston, move the cable with a slider and clamps, which, when pulled out of the housing, are opened to the required angle to release the filter. The plates of the filter under the action of the spring are expanded by 90-120 and the teeth are fixed in the wall of the vein. After that, the applicator is removed from the vein. The use of the filter improves the inhibitory anti-embolism effect not only due to the slit-like deformation of the vein, but also by introducing a plate filter into its lumen with holes that allow the blood flow to be maintained without the risk of emboli.
