摘要:
An electro-polymeric articulated endoscope and method of insertion are described herein. A steerable endoscope having a segmented, elongated body with a manually or selectively steerable distal portion 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 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.
