<p>A flexible shaft comprising a flexible outer tube (10) containing a shaft core with specially designed links (18) that closely fit within the smooth interior of the outer tube (10). The links (18) are substantially rectangular and have construction which limits a flex angle between links. The links (18) may include stop surfaces (17) which limits the flex angle to prevent kinking or limit longitudinal movement of the links (18) with respect to one another.</p> |
