First Claim
1. Flexible cannula with a tube whose distal zone is introducible into the inside of the body through a trocar puncture point, and with a top piece attached to its proximal end, the top piece having a proximal end face with an opening and a seal capable of engaging surgical instruments, and which is separately closeable by a closure device arranged in the inside of the top piece, said cannula characterized in that the tube is made from a flexible material and that the top piece is divided into a housing which has a flat proximal end and contains the closure device;
- and a flexible intermediate tube which, starting from the proximal end of the housing, extends along the longitudinal axis of the cannula.
