Description

Изобретение относитс  к медицине, а +1менно к устройствам дл  наложени  анастомозов на трубчатые органы.
Известен хирургический сшивающий аппарат дл  наложени  компрессионных анастомозов на органы пищеварительного тракта , содержащий трубчатый скобочный корпус с магазином дл  скобок, упорную головку со штоком и эластичной шайбой, толкатель с ножом, компрессионные кольца, механизм выбора зазора прошивани  и привод механизма прошивани  I.
Недостатком известного аппарата  вл етс  травматизаци  тканей при извлечении аппарата из трубчатого органа после наложен .и  анастомоза.
. Цель изобретени  - атравматичкое извлечение аппарата из трубчатого органа после наложени  анастомоза.
Поставленна  цель достигаетс  тем, что в хирургическом сшивающем аппарате дл  наложени  компрессионных анастомозов на органы пищеварительного тракта, содержащем трубчатый скобочный корпус с магазином дл  скобок, упорную головку со штоком и эластичной шайбой, толкатель с ножом, компрессионные кольца, механизм выбора зазора прошиваии  и привод механизма прошивани , упорна  головка состоит из съемно установленной на штоке втулки с пазами и секторов с выступами, взаимо .действующими с пазами втулки, причем на одном из секторов выполнен зуб, в штоке выполнен продольный паз, а на толкателе установлена пластинчата  пружина с зубом размещенна  в пазу штока с возможностью взаимодействи  с зубом сектора, при этом все секторы св заны между собой, м гкой лигатурой и один из них соединен м гкой лигатурой с втулкой.-w
На фиг. 1 показано устройство, общий вид с разрезом по осевой линии вдоль корпуса; на фиг... 2 - сечение А-А на фиг. 1; на фиК 3 -упорна  головка аппарата, сектора которой соединены лигатурой; на фиг. 4 - упорна  головка, разрез по осевой линии после наложени  aHacYoMO3a.
Устройство содержит трубчатый скобочный корпус 1 со скобочным магазином 2, в каЖдом скобочном пазу 3 которого находитс  П-образна  металлическа  скоба 4, толкатель 5 с трубчатым штоком 6, головкой 7, с лепестками 8, укрепленным на головке 7 ножом 9 и пластинчатой пружиной 10 с зубом 11, неподвижную ручку 12, подвижную ручку 13 с возвратной пружиной, гайку 14 механизма выбора зазора прошивани , компрессионные кольца 15 и упорную головку с лунками 17 дл  загиба скобок 4 с эластичной шайбой 18 и штоком 19, конец 20 которого образует с гайкой 14 механизма выбора зазора прошивани  пару винт-гайка.
На гайке 14 выполнена кругова  проточка 21, а на трубчатом скобочном корпусе
установлен штифт 22, который одним своим концом входит в круговую проточку 21, благодар  чему гайка 14 может свободно вращатьс  вокруг своей оси, но лишена 5 поступательного перемещени  относительно корпуса I.
На трубчатом штоке б толкател  5 выполнена вилка 23, между выступами которой расположен конец 24 подвижной ручки
13, а сама ручка 13 подвижно укреплена rta кронштейне 25 скобочного корпуса 1 с помощью оси 26 и ее возвратна  пружина упираетс  в неподвижную ручку 12. В каждом скобочном пазу 3 помещаетс  одна металлическа  П-образна  скобка 4 и лепесток 8
5 толкател  5.
Упорна  головка 16 выполнена разборной . Она состоит из упорной, съемно установленной на штоке 19 втулки 27 и секторов 28-31. Секторы установлены на втулке 27 съемно с помощью Т-образных выступов 32, которые вход т в Т-образные пазы 33 втулки 27. Крепление секторов на втулке 27 может осуществл тьс , например, .с помощью трени . На одном из секторов, например 28, выполнен зуб захвата 34.
5 На втулке 27 подвижно установлена гайка 35 с круговой проточкой 36. Штифт 37 закреплен на втулке 27 и одним своим концом входит в круговую проточку 36, благодар  чему гайка 35 может свободно вращатьс  вокруг своей оси, но лишена посту0 пательных перемещений относительно головки 16. Гайка 35 имеет внутреннее резьбовое отверстие 38, с помощью которого она имеет резьбовое соединение с заостренным концом 39 штока 19. В упорной головке 16 помещена эластична  щайба 18 дл  проре5 зани  на ней ткани, выполненна  преимущественно из поливинилхлорида.
Шток 9 имеет резьбовой хвостовик 20 и резьбовой заостренный конец 39, а вдоль штока выполнен паз 40, в котором разме0 щены пластинчата  пружина 10/ и зуб 34 Компрессионные кольца 15, имеющие П-образное поперечное сечение, надеты на круговые выступы трубчатого CKo6o4Horq корпуса 1 и упорной головки 16. На секторах и втулке 27 выполнены отверсти  41 под
5 лигатуру 42.
Устройство работает следующим образов Подготовка аппарата к работе. Вращением гайки 35 против часовой стре лки упорную головку 16 снимают с заостренного конца 39 штока 19. Скобочные пазы 3 зар жают П-образными металлическими скобками. На кольцевой край скобочного корпуса 1 и кольцевой край упорной головки 16 надевают компрессионные кольца 15. Затем на резьбовой заостренный конец 39 што5 ка 19 надевают эластичную шайбу 18 и упор, ную головку 16 с резьбовым отверстием 38, и вращением гайки 35 по часовой стрелке упорную головку 16 закрепл ют на резьбовом заостренном конце 39 штока 19. Секторы 28-31 и втулку 27 через отверсти  41 последовательно св зывают м гкой лигатурой 42. Аппарат готов к работе.
При оперативном доступе и общеприн тым методикам вокруг штока 19 накладывают кисетиые швы. Вращением гайки 14 выбора зазора прощивани  по часовой стрелке устанавливают необходимый зазор прощивани . После этого нажатием на подвижную ручку 13 толкатель 5 с ножом 9 и пружиной 10 подают в сторону упорной головки 16. При этом лепестки 8 толкател  5 выталкивают из скобочных пазов 3 скобки 4, которые, проколов своими заостренными ножками компрессионные кольца 15 и стенки органа, упираютс  в лунки 17 упорной головки 16, загибаютс  в В-образную форму, прочно соедин   стенки органа и.зажима  их между эластичными кольцами. Таким образов создаетс  компрессионный анастомоз. Одновременно с толкателем 5 в сторону упорной головки подаютс  нож 9 и пружина 10. Нож 9, вреза сь в ткани органа на эластичной щайбе 18и внедр  сь в эластичную щайбу 18, стабильно прорезает ткань и эластичную щайбу 18, образу  отверстие между полыми органами. При этом кисетные щвы вместе с узлами и эластична  шайба 18 окажутс  внутри ножа 9 за исключением узкого ободка эластичной шайбы 18, ко54
тора  окажетс  иа ноже 9. Пружина 10 своим зубом 11 захватывает зуб 34 упорного сегмента 28. Прошивание закончено. Вращением гайки 14 выбора зазора прошивани  против часовой стрел1 и упорна  головка 16 отводитс  от скобочного корпуса 1, но сектор 28, удерживаемый пружиной 10, соскальзывает с упорной втулки 27 и посредством легкого потр хивани  освобождаетс  от зуба пружины и компрессионного кольца. Так как секторы 28-31 и втулка 27 св заны между собой м гкой лигатурой, то секторы 28-31 начинают один за другим соскальзывать с втулки 27, и на штоке 19 остаетс  только упорна  втулка 27, а секторы 28-31 образуют гирл нду, котора  легко проходит через отверстие, вырезанное но-. жом 9, при извлечении аппарата из полого органа. Работа аппаратом закончена.
Предлагаемый аппарат легко извлекаетс  из трубчатого органа, например пр мой кишки, после наложени  компрессионного анастомоза, не нанос  дополнительной травмы в зоне шва, в результате чего улучщаетс  послеоперационное течение болезни, уменьшаетс  количество послеоперационных несосто тельностей швов, уменьшаетс  количество стационарных койко-дней, уменьшаетс  количество летальных исходов.
