Abstract
(EN)
A surgical instrument for cutting a tissue and related methods includes a shaft, a cutting member, and an axial adjustment coupling. The shaft and the cutting member are configured to articulate from a first configuration toward a second configuration and respectively have distal and proximal shaft ends distal and proximal member ends. The cutting member is disposed within the shaft and configured to cyclically move relative to the shaft. The axial adjustment coupling is configured to longitudinally move the proximal member end relative to the proximal shaft end while articulating the shaft and the cutting member from the first configuration toward the second configuration. Thereby, the axial adjustment coupling inhibits movement of the distal member end relative to the distal shaft end for maintaining alignment between a shaft window opening in the shaft and a cutting window opening in the cutting member.

La présente invention se rapporte à un instrument chirurgical permettant de découper un tissu et comprenant un arbre, un élément de découpe et un accouplement d'ajustement axial, et à des procédés associés. L'arbre et l'élément de découpe sont conçus pour s'articuler à partir d'une première configuration vers une seconde configuration et ont respectivement des extrémités distales et proximales d'arbre et des extrémités distales et proximales d'élément. L’élément de découpe est disposé à l’intérieur de l'arbre et est conçu pour se déplacer cycliquement par rapport à l'arbre. L'accouplement d'ajustement axial est conçu pour déplacer longitudinalement l'extrémité proximale d'élément par rapport à l'extrémité proximale d'arbre tout en articulant l'arbre et l'élément de découpe de la première configuration vers la seconde configuration. Ainsi, l'accouplement d'ajustement axial empêche le mouvement de l'extrémité distale d'élément par rapport à l'extrémité distale d'arbre pour maintenir l'alignement entre une ouverture de fenêtre d'arbre dans l'arbre et une ouverture de fenêtre de coupe dans l'élément de découpe.
