WIRE SPRING GUIDE FOR FLEXIBLE ENDOSCOPE

摘要

A medical device having a flexible shaft is provided, the flexible shaf t including an active deflection section. The medical device also includes at least one control wire passing through at least a portion of the flexible shaft such that actuation of the at least one control wire causes deflection of th e active deflection section of the flexible shaft. At least one control wire guide is provided which surrounds the at least one control wire along at least a portion of a length thereof. The at least one control wire guide is formed from a superelastic metal alloy and is configured as a helical spring.
