ABSTRACT:
A flexible cannula consists of a flexible tube, whose distal zone is introducible into the inside of the body through a trocar puncture point, and a top piece. The top piece is divided into a housing which is flat when seen in the direction of the longitudinal axis of the cannula and which is secured at the proximal end of the tube and contains a closure device and a flexible intermediate tube which, starting from the proximal end wall of the housing, extends along the longitudinal axis of the cannula.
