摘要：An endoscopic instrument for controlled introduction of tubular members inthe body includes a blade assembly having a blade for being introduced in the body toretract or manipulate anatomical tissue for introduction of a tubular member at a site inthe body, a tubular member assembly having a tubular member with a distal end forbeing introduced at the site in the body and a remote viewing assembly having a distalend for being positioned in the body to permit introduction of the tubular member atthe site in the body to be confirmed visually at a location remote from the site in thebody. The distal end of the tubular member and the distal end of the remote viewingdevice are movable along the blade to introduce the tubular member distal end at thesite in the body. A method of introducing a tubular member at a site in the body includesthe steps of inserting a blade of an instrument in the body, retracting anatomical tissuewith the blade, moving a distal end of a tubular member of the instrument distally alongthe blade to introduce the distal end of the tubular member at the site in the body andvisualizing introduction of the tubular member at the site in the body with a remoteviewing device from a location remote from the site in the body.
