Изобретение относитс к медицинской технике, а именно к устройствам лечени заболеваний аорты, осложненными расслаивающей аневризмой в острой фазе.The invention relates to medical technology, namely to devices for the treatment of diseases of the aorta complicated by dissecting aneurysm in the acute phase.
Известно устройство дл рассечени стенок сосудов, содержащее насос и св занный с ним трубопровод, на конце которого установлен полый контейнер с окнами, в котором установлены эластичный баллон, соединенный с трубопроводом, и скальпель 1.A device for dissecting vessel walls is known, comprising a pump and a pipeline connected to it, at the end of which a hollow container with windows is installed, in which an elastic balloon connected to the pipeline and a scalpel 1 are installed.
Однако известное устройство имеет сложную конструкцию, трудоемко в управлении, что замедл ет и осложн ет работу хирурга.However, the known device has a complex structure, time-consuming to manage, which slows down and complicates the work of the surgeon.
Цель изобретени - упрощение конструкции устройства.The purpose of the invention is to simplify the design of the device.
Эта цель достигаетс тем, что в устройстве дл рассечени стенок сосудов, содержащем насос и св занный с ним трубопровод, на конце которого установлен полый контейнер с окнами, в котором установлены эластичный баллон, соединенный с трубопроводом , и скальпель, последний выполнен в виде плоской пружины с режущим элементом на конце, причем пружина взаимодействует с эластичным баллоном.This goal is achieved by the fact that in a device for dissecting vessel walls, comprising a pump and a pipeline connected to it, at the end of which a hollow container with windows is installed, in which an elastic balloon connected to the pipeline and a scalpel are installed, the latter is made in the form of a flat spring with a cutting element at the end, and the spring interacts with an elastic balloon.
На чертеже изображено устройство дл рассечени стенок сосудов, общий вид.The drawing shows a device for cutting the walls of blood vessels, a general view.
Устройство дл рассечени стенок сосудов содержит насос 1 и св занный с ним трубопровод , на конце которого установлен полый контейнер 3 с окнами А, в котором установлены эластичный баллон 4, соединенный с трубопроводом 2, и скальпель 5, при этом скальпель 5 выполнен в виде плоской пружины с режущим элементом 6 на конце, причем пружина взаимодействует с эластичным баллоном 4.A device for dissecting vessel walls comprises a pump 1 and a pipeline connected to it, at the end of which a hollow container 3 with windows A is installed, in which an elastic cylinder 4 connected to pipeline 2 and a scalpel 5 are installed, the scalpel 5 being made in the form of a flat springs with a cutting element 6 at the end, and the spring interacts with an elastic cylinder 4.
Устройство работает следующим образомThe device works as follows
10 У больного с острой фазой расслаивающей аневризмой аорты под местной анастезией выдел ют общую бедренную артерию с последующей поперечной артериотомией. В образовавщийс просвет артерии ввод т 15 устройство и проталкивают в полость аорты под рентгенотелевизионным контролем. При достижении дистального конца аневризматического мешка насосом 1 эластичный баллон 4 накачивают физологическим 2Q раствором до упора в противоположную стенку аорты. Эластичный баллон 4 при этом отгибает скальпель 5, выполненный в виде консольной пружины, таким образом, что скальпель 5 прижимаетс к внутренней стенке полого контейнера 3, а режущий эле10 In a patient with an acute phase of dissecting aortic aneurysm, a common femoral artery is isolated under local anesthesia, followed by transverse arteriotomy. A device is inserted into the resulting lumen of the artery and pushed into the aortic cavity under x-ray control. When the distal end of the aneurysmal bag is reached by pump 1, an elastic balloon 4 is pumped with a physiological 2Q solution until it stops against the opposite wall of the aorta. The elastic balloon 4 in this case bends the scalpel 5, made in the form of a cantilever spring, so that the scalpel 5 presses against the inner wall of the hollow container 3, and the cutting element
