ABSTRACT:
An access cannula for endoscopic operations comprises a cannula tube, a valve body unit having a valve housing and a valve mounted in the valve housing. The valve body can be connected releasably as a completely assembled valve body unit to one end of the cannula tube. The valve of the valve body ensures a tight closure of the cannula tube at said one end, but allows an instrument to be passed through the valve body unit and the cannula.
