Abstract

The invention relates to medical engineering and equipment. The device for establishing compression anastomoses comprises two bushes (1 and 4) arranged coaxially and slidably with respect to each other. The bush (1) has the flange (2) at one end and the collet (3) at the other. The bush (4) has the flange (5) and the movable ring (6). The spring (7) is interposed between the flange (5) and the ring (6). From outside the bush (4) is covered by the elastic sheathing (8) that passes into the two-lumen tube (9), one of its lumens being communicated with the interior of the sheathing (8), while the other lumen opens outwards immediately above the sheathing (8). The device is adapted predominantly for establishing compression anastomoses in the alimentary tract. <IMAGE>

Description

Изобретение относитс  к медицине, а именно к устройствам дл  наложени  компрессионных анастомозов на полые органы.The invention relates to medicine, namely to devices for applying compression anastomoses to hollow organs.

Известно устройство дл  наложени  компрессионных анастомозов, содержащее втулку с фланцем, вход щую во вторую втулку с подвижным кольцом и пружиной.A device for applying compression anastomoses is known, comprising a sleeve with a flange that enters the second sleeve with a movable ring and a spring.

Недостатком известного устройства  вл етс  то, что оно не обеспечивает раннего зондового питани  в послеоперационном периоде с одновременным осуществлением декомпрессии в зоне анастомоза и свободного извлечени  устройства в оральном направлении .A disadvantage of the known device is that it does not provide early probe feeding in the postoperative period with simultaneous decompression in the anastomosis zone and free removal of the device in the oral direction.

Цель изобретени  - обеспечение раннего зондового питани  в послеоперационном периоде с одновременным осуществлением декомпрессии в зоне анастомоза и свободного извлечени  устройства в оральном направлении .The purpose of the invention is to provide early probe feeding in the postoperative period with simultaneous decompression in the anastomosis zone and free removal of the device in the oral direction.

Указанна  цель достигаетс  тем, что в устройстве дл  наложени  компрессионных анастомозов, содержащем втулку с фланцем, вход щую во вторую втулку с подвижным кольцом и пружиной, втора  втулка и подвижное кольцо покрыты эластичной оболочкой , соединенной внутренней полостью с двухпросветной трубкой, причем один из просветов выведен наружу непосредственно над втулкой.This goal is achieved by the fact that in a device for applying compression anastomoses, comprising a sleeve with a flange, a second sleeve with a movable ring and a spring, the second sleeve and the movable ring are covered with an elastic sheath connected by an internal cavity with a double lumen tube, and one of the clearances is removed out directly above the sleeve.

На фиг. 1 изображено устройство с соединенными втулками, общий вид; на фиг. 2 - концы кишок с введенными внутрь втулками перед соединением; на фиг. 3 - соединенные при помощи устройства концы кишок; на фиг. 4 - выведение устройства после отторжени  и срастани  стенок соединенных кищок.FIG. 1 shows a device with coupled bushings, a general view; in fig. 2 - the ends of the intestines with inserted into the sleeves before connecting; in fig. 3 - connected with the device ends of the intestines; in fig. 4 shows the removal of the device after the rejection and accretion of the walls of the connected picks.

Устройство дл  наложени  компрессионных анастомозов содержит втулку 1 с фланцем 2 на одном конце и цангой 3 на другом. Втулка 1 входит во втулку 4 также имеющую фланец 5. Во втулке 4 установлено подвижное кольцо 6 и пружина 7, упирающа с  одним концом во фланец 5, а другим в кольцо 6. Снаружи втулка 4 покрыта эластичной оболочкой 8, переход щей в двухпросветную трубку 9, причем один из просветов выведен наружу непосредственно над втулкой.A device for applying compression anastomoses comprises a sleeve 1 with a flange 2 at one end and a collet 3 at the other. The sleeve 1 enters the sleeve 4 also having a flange 5. The sleeve 4 is equipped with a movable ring 6 and a spring 7, abutting with one end into the flange 5 and the other into the ring 6. Outside, the sleeve 4 is covered with an elastic sheath 8, passing into a double lumen tube 9 , with one of the gaps out directly above the sleeve.

Первоначально втулки 1 и 4 наход тс  в разъединенном виде. В полость вышерасположенного органа, например кищки, ввод т втулку 4, предварительно провед  трубку 9 через пищеварительный тракт и вывед  ее через рот или пазуху носа наружу. Ли- 2 гатурой непосредственно за введенной втулкой 4 перев зывают конец кищки в виде кисета, оставив отверстие, примерно соответствующее диаметру втулки 1. В полость нижерасположенной кищки ввод т втулку 1 и лигатурой вокруг фланца 2 перев зываютInitially, the sleeves 1 and 4 are in a disconnected form. The sleeve 4 is inserted into the cavity of an upstream organ, such as pischis, having previously passed tube 9 through the digestive tract and brought it out through the mouth or sinus outside. Lead the gatura directly behind the inserted sleeve 4 to tie up the end of the pinch in the form of a pouch, leaving a hole approximately corresponding to the diameter of the sleeve 1. Insert sleeve 1 into the cavity of the downstream picklet and ligature around the flange 2 to tie

0 конец кищки с образованием кисета так, чтобы наружу выступал конец с цангой 3 (фиг. 2). Выступающий конец втулки 1 с цангой 3 ввод т во втулку 4 через имеющеес  отверстие до упора. При этом втулки 1 и 40 the end of the dagger with the formation of a pouch so that the end with the collet 3 protrudes (Fig. 2). The protruding end of the sleeve 1 with the collet 3 is inserted into the sleeve 4 through the existing hole until it stops. In this case, the sleeves 1 and 4

соедин ютс  неразъемно при помощи цанги 3. Концы кищок соединены (фиг. 3). Стенки кишок по периметру анастомоза начинают сдавливатьс  кромками фланца 2 и кольца 6 под действием пружины 7, сжавшейс  при соединении втулок 1 и 4. Проис0 ходит процесс срастани  внешних слоев стенок кишок и отторжени  внутренних, подвергшихс  некрозу. В этот период благодар  двухпросветной трубке 9 осуществл етс  раннее зондовое питание больного и создание благопри тных условий в зоне анастомоза путем декомпрессии через второй просвет трубки. Через определенное врем  процесс заканчиваетс  первичным срастанием стенок соединенных кищок и полным отторжением некротизированных, сжатых устройством тканей. they are connected in one piece using collet 3. The tips of the tweezers are connected (Fig. 3). The walls of the intestines along the perimeter of the anastomosis begin to be squeezed by the edges of the flange 2 and the ring 6 under the action of the spring 7, squeezed when the sleeves 1 and 4 are joined. A process of accretion of the outer layers of the intestinal walls and rejection of the inner ones that have undergone necrosis occurs. During this period, due to the double-lumen tube 9, the patient’s early feeding of the patient is carried out and favorable conditions are created in the anastomosis zone by decompression through the second lumen of the tube. After a certain time, the process ends with the primary accretion of the walls of the connected picks and the complete rejection of necrotic, tissue-compressed tissue.

После полного отторжени  устройства его извлекают из полости кишок, выт гива  трубку 9. Благодар  тому, что эластична  оболочка 8 принимает конусообразную форму при нат жении трубки 9, устройство легкоAfter complete rejection of the device, it is removed from the cavity of the intestines by drawing out the tube 9. Due to the fact that the elastic shell 8 takes on a conical shape when the tube 9 is tensioned, the device easily

, проходит через кардиальный жом и свободно извлекаетс  из пищеварительного тракта в оральном направлении (фиг. 4).It passes through the cardiac pulp and is freely removed from the digestive tract in the oral direction (Fig. 4).

Устройство дл  наложени  компрессионных анастомозов просто по конструкции и методике применени , дешево, обеспечивает наложение качественных анастомозов с минимальной травматизацией органов, легко извлекаетс  из пищеварительного тракта, позвол ет проводить раннее зондовое питание больного и создавать в зоне анастомоза благопри тные услови  дл  за5The device for applying compression anastomoses, simple in design and application method, cheaply, provides for the application of high-quality anastomoses with minimal trauma to the organs, is easily removed from the digestive tract, allows for early probe feeding of the patient and creates favorable conditions in the area of the anastomosis.
