An endoscopic surgery apparatus is provided, including a tubular member, a handle located on a proximal end of the tubular member, and one or more pivotable arms detachably connected to a distal end of the tubular member. The tubular member has channels along its longitudinal axis, wherein at least one of the channels is an optical channel and at least one other channel is an illumination channel. The arms have guiding channels adapted to receive surgical tools, which direct the surgical tools. The arms are interchangeable with other arms of different configurations. Also, said arms have an open and a closed position, such that when the arms are in the closed position an opening is defined allowing viewing of a surgical site via the optical channel.
