Title
(EN) TORQUE-TRANSMITTING VARIABLY-FLEXIBLE INSERTION DEVICE AND METHOD FOR TRANSMITTING TORQUE AND VARIABLY FLEXING AN INSERTION DEVICE

Abstract
(EN)
A torque-transmitting, variably-flexible insertion device includes a hollow body having a proximal end with an entrance for receiving an instrument and a distal end with a tip for protrusion of the instrument. A vacuum-activated device transitions the hollow body between a relatively flexible condition and a relatively stiff condition. A torque braid transmits torque from the proximal end toward the distal end. A method for transmitting torque and variably flexing the insertion device includes transmitting torque along the hollow body with the torque braid, applying suction to create a vacuum in the hollow body for placing the hollow body in the relatively stiff condition, and relieving the vacuum for placing the hollow body in the relatively flexible condition.
(FR)
Dispositif d'insertion à flexion variable et à transmission de couple comprenant un corps creux ayant une extrémité proximale avec une entrée pour recevoir un instrument et une extrémité distale avec une pointe pour ressortir de l'instrument. Un dispositif activé sous vide permet la transition du corps creux entre une condition relativement flexible et une condition relativement rigide. Une tresse de couple transmet le couple de l'extrémité proximale vers l'extrémité distale. Un procédé de transmission de couple et de flexion variable du dispositif d'insertion comprend la transmission de couple, le long du corps creux avec la tresse de couple, en appliquant une aspiration afin de créer un vide dans le corps creux pour placer le corps creux dans la condition relativement rigide et décharger le vide pour placer le corps creux dans la condition relativement flexible.
