Abstract
An expandable anchor mechanism for tentatively fixing a flexible tubular section of a bioptic or surgical treating instrument inserted in a biopsy channel of an endoscopic insertion rod. During a bioptic or surgical treatment, a fore end portion of the treating instrument is fixedly gripped by the anchor mechanism to stabilize a movable operating member of the instrument which is protruded into a body cavity from the distal end of the biopsy channel. The anchor mechanism includes an anchor control means for remote-controlling an anchor member to and from an expanded state projecting into the biopsy channel to grip a treating instrument and a flatly contracted state permitting movements of the treating instrument in the biopsy channel.
