Title (EN) ACTIVATED POLYMER ARTICULATED INSTRUMENTS AND METHODS OF INSERTION
(FR) INSTRUMENTS ARTICULES A POLYMERE ACTIVE, ET METHODES D'INTRODUCTION
Abstract:
(EN) An electro-polymeric articulated endoscope (90) and method of insertion are described herein. A steerable endoscope (90) having a segmented, elongated body (96, 98, 100) with a manually or selectively steerable distal portion (102) and an automatically controlled proximal portion can be articulated by electro-polymeric materials. These materials are configured to mechanically contract or expand in the presence of a stimulus, such as an electrical field. Adjacent segments of the endoscope (90) can be articulated using the electro-polymeric material by inducing relative differences in size or length of the material when placed near or around the outer periphery along a portion of the endoscope.
(FR) L'invention concerne un endoscope articulé à polymère électroactif, et une méthode d'introduction d'endoscope. Cet endoscope peut être guidé et comprend un corps allongé, segmenté, comprenant une section distale pouvant être guidée manuellement ou sélectivement, et une section proximale à commande automatique qui peut être articulée par le biais de matériaux polymères électroactifs. Ces matériaux sont conçus pour se contracter et se dilater mécaniquement en présence d'un stimulus tels qu'un champ électrique. Les segments adjacents de l'endoscope peuvent être articulés par la création de différences relatives de dimension ou de longueur dans le matériau polymère électroactif disposé à proximité ou autour de la périphérie externe d'une section de l'endoscope.
