Description
Изобретение относитс к медицине, а именно к трахеобронхиальной хирургии, и может быть использовано дл реконструктивных пластических операций на трахее.The invention relates to medicine, namely to tracheobronchial surgery, and can be used for reconstructive plastic surgery on the trachea.
Известен протез дл замещени об- ширных циркул рных дефектов трахеи, содержащий герметизирующий элемент в видесиликоновой трубки и соединительный элемент, выполненный в виде двух концевых фиксационных манжет.A prosthesis is known for replacing extensive tracheal circular defects comprising a sealing element in a silicone tube and a connecting element made in the form of two end fixation sleeves.
Недостатки известной конструкции протеза обусловлены возникающими послеоперационными осложнени ми как в зоне замещени циркул рного дефекта трахеи, так и со стороны легких.The disadvantages of the known prosthesis design are caused by the postoperative complications arising both in the area of replacement of the circular defect of the trachea and on the part of the lungs.
Осложнени в области замещени трахеи , посто нно поддерживающийс воспа лительный процесс в полости между протезом и образующейс вокруг протеза капсулой, отслоение врастающих тканей от фиксационных манжет смещени , деформации , перегибы протеза, прорезь еа- ние швов и нарушение герметичности в области анастомозов - св заны с отсутствием врастани тканей организма в стенку протеза, выраженным нат жением в области анастомозов. Осложени со стороны легких, пневмоторакс, пневмони - также наход тс в пр мой зависимости от указанных причин.Complications in the field of tracheal replacement, a constantly maintained inflammatory process in the cavity between the prosthesis and the capsule forming around the prosthesis, the detachment of the growing tissues from fixation cups of displacement, deformation, bends of the prosthesis, the cutting of the seams and leakage in the anastomosis area are associated with absence of ingrowth of body tissues into the wall of the prosthesis, pronounced tension in the anastomoses area. Pulmonary complications, pneumothorax, pneumonia are also directly dependent on the indicated causes.
Целью изобретени вл етс повышение надежности фиксации протезаThe aim of the invention is to improve the reliability of fixation of the prosthesis.
Указанна цепь достигаетс наличием соединительного элемента протеза, покры зающего силиконовую трубку (герметизиру ющий элемент), и накидных манжет.This chain is achieved by the presence of a connecting element of the prosthesis covering the silicone tube (sealing element) and cuffs.
На чертеже изображен протез трахеи.The drawing shows the prosthesis of the trachea.
Протез состоит из силиконовой трубки I с кольцевыми выступами 2 на концах, расположенными в 4 мм от краев протеза, сое- динительного элемента 3, размещенного между кольцевыми выступами и жестко св занною с силиконовой трубкой, и накидных манжет 4, вл ющихс продолжением соединительного элемента и образующихс за счет отсутстви св зи между силиконовой трубкой и соединительным элементом по кра м протеза, начина от кольцевых выступов , и не выход щих за пределы силиконовой трубки.The prosthesis consists of a silicone tube I with annular projections 2 at the ends located 4 mm from the edges of the prosthesis, a connecting element 3 placed between the annular projections and rigidly connected with the silicone tube, and the collar 4, which is a continuation of the connecting element and formed due to the lack of communication between the silicone tube and the connecting element along the edges of the prosthesis, starting from the annular projections and not extending beyond the limits of the silicone tube.
Операци протезировани трахеи осуществл етс следующим образом.The tracheal prosthesis is performed as follows.
После иссечени необходимого участка трахеи протез с завернутыми накидными манжетами фиксируетс к концам трахеи за кольцевые выступы так. что зауженные поAfter excision of the necessary part of the trachea, the prosthesis with the wrapped cap sleeves is fixed to the ends of the trachea by the annular projections. that narrowed by
наружному диаметру участки силиконовой трубки телескопически вход т в просвет трахеи до кольцевых выступов, к которым концы трахеи пришиваютс отдельными узловыми швами. После этого на линию швов анастомозов между трахеей и протезом наворачиваютс накидные манжеты, которые по краю прикрепл ютс к наружной поверхности трахеи также отдельными узловыми швами, усилива таким образом фиксацию протеза двойным р дом швов.The outer diameter portions of the silicone tube are telescopically inserted into the lumen of the trachea to the annular protrusions to which the ends of the trachea are sutured with separate interrupted sutures. Thereafter, cap sleeves are screwed onto the suture line of the anastomoses between the trachea and the prosthesis, which along the edge are attached to the outer surface of the trachea also by separate interrupted sutures, thus strengthening the prosthesis with a double row of seams.
Медико-биологические испытани протеза проведены в эксперименте на 33 беспородных собаках, которым проводили удаление 8-14 хр щевых полуколец грудного отдела трахеи с замещением дефекта описанным протезом.The biomedical tests of the prosthesis were carried out in an experiment on 33 mongrel dogs, which carried out the removal of 8–14 hilar semirings of the thoracic trachea with the replacement of the defect by the described prosthesis.
Исследованием установлено, что протез легко фиксируетс к концам трахеи, не вызывает выраженной реакции со стороны организма; стенозов в зоне анастомозов, роста в просвет трахеи гранул ционной ткани не отмечено.An investigation has established that the prosthesis is easily fixed to the ends of the trachea, does not cause a pronounced reaction on the part of the body; no stenosis in the anastomosis zone, no growth in the lumen of the trachea granulation tissue.
Внутренн поверхность протеза эпителиальной тканью не покрываетс Происходит надежна фиксаци протеза по всей площади наружной поверхности за счет прорастани гранул ционной и фиброзной тканей в петли соединительного элемента. Зона соединени трахеи с протезом цирку- л рно укрепл етс двойным р дом швов и дополнительно герметизируетс накидными манжетами, которые также прорастают соединительной тканью. Деформации перегибов протеза, нарушени герметичности в зоне анастомозов не отмечалось. Функциональное состо ние трахеобронхиального дерева и легких у оперированных животных существенно не изменилось.The inner surface of the prosthesis is not covered with epithelial tissue. The prosthesis is securely fixed over the entire outer surface area due to the germination of the granulation and fibrous tissues in the loops of the connecting element. The tracheal junction with the prosthesis is circularly reinforced with a double row of sutures and is additionally sealed with a cuff that also grows with connective tissue. No deformations of the prosthesis, no leakage in the area of the anastomoses was noted. The functional state of the tracheobronchial tree and lungs in the operated animals did not change significantly.
Применение данного протеза трахеи не усложн ет технику реконструктивных операций на трахее, практически не увеличивает продолжительность операции, по своим прочностным свойствам значительно выше предложенных ранее протезов и превышает их по геометрическим качествам и аэростазу в зоне анастомозов.The use of this prosthesis of the trachea does not complicate the technique of reconstructive operations on the trachea, practically does not increase the duration of the operation, its strength properties are much higher than the previously proposed prostheses and exceed them in geometric qualities and aerostasis in the anastomoses area.
