Title (EN) ANGLED ROTARY TISSUE CUTTING INSTRUMENT
(FR) INSTRUMENT DE COUPE DE TISSU ROTATIF A INCLINAISON
Abstract:
(EN) The present invention is generally characterized in an angled rotary tissue cutting instrument (10) including an outer blade assembly (12) having a rigid tubular member (18) with proximal and distal portions connected by a bend (22) and an inner blade assembly (14) rotatably disposed within the outer blade assembly (12) and including a tubular drive shaft (36) at a proximal end, a cutting tip (38) at a distal end and a flexible coupling (40) disposed between the drive shaft (36) and the cutting tip (38). The drive shaft (36) and cutting tip (38) include neck portions (46, 60) which are disposed telescopically within proximal and distal ends of the coupling (40). The flexible coupling (40) is formed of a flexible polymeric material and each of the neck portions (46, 60) includes a lateral opening (52, 62) defining a predetermined flow path for the polymeric material during fabrications so that the flexible polymeric coupling (40) includes flow portions (66') extending into the openings (52, 62) in the neck portions (46, 60) of the drive shaft (36) and the cutting tip (38) to form permanent, interlocking mechanical joints therewith capable of receiving and transmitting torque.
(FR) Cette invention porte sur un instrument de coupe de tissu rotatif à inclinaison (10) comportant un bloc de coupe externe (12) pourvu d'un élément tubulaire rigide (18) dont les parties proximale et distale sont connectées par un coude (22) ainsi qu'un bloc de coupe interne (14) monté rotatif dans le bloc de coupe externe (12) et comprenant un arbre d'entraînement tubulaire (36) sur l'extrémité proximale, une tête de coupe (38) à l'extrémité distale et un raccord souple (40) entre l'arbre d'entraînement (36) et la tête de coupe (38). L'arbre d'entraînement (36) et la tête de coupe (38) comportent des éléments de col (46, 60) montés télescopiques dans les extrémités proximale et distale du raccord (40). Le raccord souple (40) est fait d'un polymère souple et chacun des éléments de col (46, 60) comporte une ouverture latérale (52, 62) délimitant un passage prédéterminé du polymère durant la fabrication, de sorte que ce raccord polymère souple (40) comporte des parties de flux (66') s'étendant dans les ouvertures (52, 62) des éléments de col (46, 60) de l'arbre d'entraînement (36) et de la tête de coupe (38) pour constituer des joints mécaniques permanents multiprises, capables, en outre, de recevoir et de transmettre un couple.
