Title
(EN) A FLUID DELIVERY DEVICE
(FR) DISPOSITIF DE DISTRIBUTION DE FLUIDE DESTINE A ETRE UTILISE AVEC DES INSTRUMENTS D'ANASTOMOSE, D'AGRAFAGE ET DE RESECTION
Abstract
(EN) A fibrin injection mechanism for use in combination with an anastomosing and stapling attachement for an electromechanical device driver comprises a cylindrical dispensing chamber (95) adjacent the cylindrical blade (75) of the attachement and containing a sac (100) filled with fibrin, a plurality of channels extending (90) within the blade (75) communicating between the dispensing chamber (95) and the cutting edge (75) of the blade, such that when the turning drive shaft is activated, the staple driver (65) of the attachment moves forward to push a plurality of staples (60) through corresponding staple ports (55) and against the anvil (20) of the attachment to pass through and staple together the target tissue, while the blade driver (75) of the attachment moves forward to cut the unwanted residual tissue (post stapling), while a plunger (delivery) driver (110) moves forward through the dispensing chamber (95) to compress the sac (100) to its break point, releasing the fluid medication into the dispensing chamber (95), and eventually pushing the medication through the channels (90) to deliver the fibrin to the cutting edge of the blade (75) and thus to the site of the newly stapled target tissue to accelerate the healing process.
(FR) L'invention concerne un mécanisme d'injection de fibrine destiné à être utilisé de manière combinée avec un instrument d'anastomose et d'agrafage destiné à un dispositif d'entraînement électromécanique. Ce mécanisme comprend une chambre de distribution cylindrique adjacente à la lame cylindrique de l'instrument et contenant un sac plein de fibrines, une pluralité de canaux s'étendant dans la lame et reliant la chambre de distribution et le fil de la lame, de sorte que lorsque l'arbre d'entraînement rotatif est activé, le dispositif d'entraînement d'agrafage s'avance et pousse une pluralité d'agrafes à travers des ports d'agrafage correspondants contre l'enclume de l'instrument de manière que les agrafes traversent le tissu cible et l'agrafent, le dispositif d'entraînement de l'instrument s'avance et coupe le tissu résiduel inutile (après l'agrafage), un dispositif d'entraînement (et de distribution) du piston s'avance à travers la chambre de distribution et finalement pousse le médicament dans les canaux pour amener la fibrine au fil de la lame et, par conséquent, au site du tissu cible nouvellement agrafé afin d'accélérer le processus de guérison.
