An anastomotic ring applier system (30) for deploying a first compression ring (36) and a second compression ring (39) comprises an anastomotic applier (32) with a second ring carrier (38) adapted to hold the second compression ring (39), a ring approximation device (37) with a first portion (42) connectable to an external first ring carrier device (31) which supports the first compression ring (36) and a second portion (43) connected to the second ring carrier device (38), wherein the first portion (42) and the second portion (43) are connected to one another by a piston-cylinder thrust unit (66). A fluid pump device is connected to a pressure chamber (67) of the piston-cylinder thrust unit (66) so that operation of the fluid pump raises the fluid pressure inside the pressure chamber (67) and causes the first and second portions (42, 43) to translate to one another to approximate and interconnect the compression rings (36, 39).
La présente invention concerne un système d'application d'anneau anastomotique (30) qui permet de déployer un premier (36) et un second anneau de compression (39). Ledit système comprend : un applicateur anastomotique (32) doté d'un second support annulaire (38) conçu pour retenir le second anneau de compression (39) ; un dispositif d'approximation d'anneau (37) pourvu d'une première partie (42) pouvant se raccorder à un dispositif externe de support du premier anneau (31) qui soutient le premier anneau de compression (36) et d'une seconde partie (43) reliée au dispositif de support du second anneau (38), la première (42) et la seconde partie (43) étant reliées entre elles par une unité de propulsion à piston/cylindre (66). Un dispositif de pompe à fluide est raccordé à une chambre de pression (67) de l'unité de propulsion à piston/cylindre (66) pour que l'action de la pompe à fluide augmente la pression du fluide dans la chambre de pression (67) et entraîne le déplacement de la première et la seconde partie (42, 43) de l'une à l'autre en vue de rapprocher et interconnecter les anneaux de compression (36, 39).
