Title (EN) SURGICAL INSTRUMENT FOR PERFORMING CIRCULAR ANASTOMOSES ON LARGE INTESTINE
(FR) INSTRUMENT CHIRURGICAL POUR PRATIQUER UNE ANASTOMOSE CIRCULAIRE SUR LE GROS INTESTIN
Abstract: front page image
(EN)A surgical instrument for performing circular anastomoses on various parts of the large intestine, comprising a cylindrical casing with a mandrel (2) at one of its ends and mounted coaxially inside the casing, a rod (3) with a circular blade (4) provided with a mechanism for its longitudinal travel and a bar (6) with a supporting head (7) axially movable in relation to the rod (3), and a mechanism (8) for performing circular anastomoses. The mechanism (8) for performing circular anastomoses consists of two parts one of which is mounted on the mandrel (2) and houses broaching elements interacting with the rod (3) to ensure their joint travel when performing circular anastomoses, the other part being mounted on the supporting head (7). The part of the mechanism (8) for performing circular anastomoses which is mounted on the mandrel (2) comprises two rings (9, 10) placed at some distance one from the other, a number of the broaching elements executed as needles (11) being spaced equidistantly along a circle in the gap between them. Some needles (11) are provided with compensators (12). The part of the mechanism (8) for performing circular anastomoses which is mounted on the supporting head (7) is constructed as a ring (14) connected to the supporting head (7) with the possibility of their disconnection in the course of performing the anastomosis. Both parts of the mechanism (8) for performing circular anastomoses are fixed to each other during the performing of circular anastomoses and are left inside the large intestine until the complete necrosis of the intestine.
(FR)Un instrument chirurgical pour pratiquer une anastomose circulaire sur diverses parties du gros intestin, comprend un corps cylindrique avec un mandrin (2) a l"une de ses extremites et, montee coaxialement a l"interieur du corps, se trouve une tige (3) avec une lame circulaire (4) pourvue d"un mecanisme d"avance longitudinale et une barre (6) avec une tete de support (7) mobile axialement par rapport a la tige (3), et un mecanisme (8) servant a pratiquer l"anastomose circulaire. Le mecanisme (8) pour effectuer une anastomose circulaire comprend deux parties dont l"une est montee sur un mandrin (2) et loge des elements de mandrinage cooperant avec la tige (3) pour associer lors de l"anastomose circulaire, l"autre partie etant montee sur la tete de support (7). La partie du mecanisme (18) qui est montee sur le mandrin (2) comprend deux anneaux (9, 10) places a une certaine distance l"un de l"autre, plusieurs elements de mandrinage etant realises sous forme d"aiguilles (11) equidistantes et disposees en cercle. Certaines de ces aiguilles (11) sont pourvues de compensateurs (12). La partie du mecanisme (8) d"anastomose circulaire qui est montee sur la tete de support (7) est construite sous la forme d"une bague (14) liee a la tete de support (7) et pouvant etre deconnectee au cours de l"anastomose. Les deux parties du mecanisme (8) pour pratiquer une anastomose circulaire sont fixees l"une a l"autre pendant l"anastomose circulaire et elles sont laissees a l"interieur du gros intestin jusqu"a la necrose totale de la partie etranglee de celui-ci.
