Adapter, extension, and connector assemblies for surgical devices

摘要

ADAPTER, EXTENSION, AND CONNECTOR ASSEMBLIES FOR SURGICAL DEVICES An assembly including an adapter assembly (100) and an extension assembly (200) for connecting an end effector (30) to an electrosurgical instrument is provided. The adapter assembly (100) includes first and second pusher assemblies (160, 180) configured for converting rotational motion into linear motion and a drive member (140) for transferring rotational motion. The extension assembly (200) includes at least one flexible band assembly (210, 230) for transferring the linear motion from the adapter assembly (100) and a trocar assembly (270) configured for converting rotational motion into linear motion. Also provided is a connection assembly (500) for connecting a first tubular member (100) to a second tubular member (200). *N / / /1 '1 ekk11
