Title (EN) SURGICAL INSTRUMENT FOR PENETRATION OF TISSUE LAYERS
(FR) INSTRUMENT CHIRURGICAL POUR LA PÉNÉTRATION DE COUCHES DE TISSU
Abstract:
(EN) An instrument for surgical insertion and penetration of tissue layers includes a shaft, a distally facing end surface, and at least one cutting feature positioned on the distally-facing end surface. The at least one cutting feature is structurally configured to be atraumatic when not rotated. The at least one cutting feature enables cutting of tissue when the at least one cutting feature is rotated about a rotational axis. The at least one cutting feature can comprise a cutting edge that is positioned tangential relative to an imaginary cylinder centered on the rotational axis and/or a cutting edge that is positioned such that a plane defined along the cutting edge does not extend through the rotational axis.
(FR) La présente invention concerne un instrument pour l’insertion et la pénétration chirurgicales de couches de tissu qui comprend une tige, une surface d’extrémité distalement orientée, et au moins un élément de coupe positionné sur la surface d’extrémité distalement orientée. L’au moins un élément de coupe est structurellement configuré pour être atraumatique lorsqu’il n’est pas mis en rotation. L’au moins un élément de coupe permet la coupe de tissu lorsque l’au moins un élément de coupe est mis en rotation autour d’un axe de rotation. L’au moins un élément de coupe peut comprendre un bord tranchant qui est positionné de façon tangentielle par rapport à un cylindre imaginaire centré sur l’axe de rotation et/ou un élément de coupe qui est positionné de sorte qu’un plan défini le long du bord de coupe ne s’étende pas à travers l’axe de rotation.
