Patent

CA 2681693

A flexible torque tube is disclosed. The torque tube can be used with an endoscope. For instance, the torque tube can be part of an endoscopic accessory having an end effector which is manipulated through the working channel of an endoscope. The torque tube can include a series of interconnected hollow tubular members extending proximally from the end effector. The tubular members can be interconnected to provide a flexible torque tube have substantially zero bending stiffness and a torsional stiffness sufficient for manipulating the end effector through the working channel of an endoscope.

L'invention concerne un tube de torsion flexible. Le tube de torsion peut être utilisé avec un endoscope. Le tube de torsion peut par exemple faire partie d'un accessoire endoscopique ayant un effecteur terminal manipulé à travers le canal de travail d'un endoscope. Le tube de torsion peut inclure une série d'éléments tubulaires creux interconnectés s'étendant de manière proximale à partir de l'effecteur terminal. Les éléments tubulaires peuvent être interconnectés pour fournir un tube de torsion flexible d'une rigidité en flexion pratiquement nulle et d'une rigidité torsionnelle suffisante pour manipuler l'effecteur terminal à travers le canal de travail d'un endoscope.
