FLEXIBLE TORQUE TUBE FOR USE WITH ENDOSCOPE

摘要

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.
