Title:
【発明の名称】流体力学的筋を伴うボアスコープまたはエンドスコープ
Document Type and Number:
Japanese Patent JPH0667378
Kind Code:
B2
Abstract:
A fluid dynamic muscle (30) contracts when air or hydraulic pressure is applied to it. The muscle has a long elastomeric bladder (32) covered by a long tubular braid (34) of flexible but inextensible fibers or filaments (35). When the bladder (32) is inflated the braid (34) is forced to expand laterally, which shortens it axially when the pressure is relieved, the muscle (30) will relax allowing a pulling force on a tendon (24) connected to a termination on its distal end to stretch it back to its original length. These fluid dynamic muscles (30) can be used for bending the articulation section of a borescope or endoscope (10).
