Изобретение относитс к медицине , а именно к устройствам дл удалени новообразований из трубчатых органов.This invention relates to medicine, in particular to devices for removing tumors from tubular organs.
Целью изобретени вл етс снижение травматичности при циркул рном иссечении тканей на внутренних стенках внутренних органов аа счет возможности визуального контрол через бронхоскоп.The aim of the invention is to reduce the trauma during the circular excision of the tissues on the inner walls of the internal organs and to account for the possibility of visual inspection through a bronchoscope.
На фиг,1 изображен эндоскопический нож с треугольными зубь ми, общий вид; на фиг.2 - эндоскопический нож с криволинейной режущей кромкой .Fig. 1 shows an endoscopic knife with triangular teeth, a general view; figure 2 - endoscopic knife with a curved cutting edge.
Нож состоит из трубки 1 с упоромThe knife consists of a tube 1 with an emphasis
2и фигурной режущей кромкой, расположенной под углом к оси и выполненной в виде разносторонних зубьев2i figured cutting edge located at an angle to the axis and made in the form of miscellaneous teeth
3с режущей кромкой на длинной стороне 4 или в виде криволинейной спирали 5 с выступом 6.3c with a cutting edge on the long side 4 or in the form of a curvilinear helix 5 with a protrusion 6.
Ножом пользуютс следующим образомThe knife is used as follows.
Нож надевают на тубус бронхоско- па. Режуща кромка ножа в исходномThe knife is put on the bronchospace tube. Cutting knife edge in the original
положении располагаетс на 2-3 мм вьше дистального конца тубуса брон- хоскопа. Диаметр тубуса бронхоскопа и диаметр ножа подбирают в зависимости от диаметра трахеи или бронхов больного.The position is located 2-3 mm above the distal end of the bronchoscope tube. The diameter of the tube of the bronchoscope and the diameter of the knife are selected depending on the diameter of the trachea or bronchi of the patient.
Перед срезанием наростов Нож выд- вигают вперед, глубина погружени ножа в тканевые разрастани регулируетс упором 2. Поворачива бронхоскоп с закрепленным с помощью упора 2 выдвинутым ножом по часовой стрелке и одновременно продвига его вперед, режущей кромкой срезают рубцовые наросты. Упор 2 при этом позвол ет контролировать центровку ножа в просвете полого органа.Before cutting the growths, the knife is thrust forward, the depth of the knife in tissue growths is regulated by the stop 2. By turning the bronchoscope with the knife extended with the help of stop 2 clockwise and pushing it forward, the cicatricial growths are cut off with the cutting edge. The stop 2 in this case allows control of the centering of the knife in the lumen of the hollow organ.
Смена стандартных тубусов с надетыми на них ножами с последовательноChange of standard tubes with worn knives on them consistently
возрастающим диаметром позвол ет производить послойное срезание тканей , увеличива тем самым просвет полых органов до необходимого размера . Через внутреннюю трубку бронхоскопа осуществл ют аспирацию крови, сгустков и срезаемых тканей.the increasing diameter allows for layer-by-layer cutting of tissue, thereby increasing the lumen of hollow organs to the required size. Through the inner tube of the bronchoscope, blood, clots and sheared tissues are aspirated.
