Abstract: A surgical endoscopic instrument with detachable end tool as a clamp, a clamp retrieving device and a method for their use is provided. The instrument comprises a clamp, removably connected by a coupling to an elongated shaft, this comprising two concentric tubes, which can rotate about each other, connected to a rotating element, that is attached to a housing, inside which a push-pull rod, driven by a handle, transmits the surgeon's commands, leading to the actuating of the end tool's jaws, as well as the clamp detachment/retrieving, from/to the elongated shaft, by operating the coupling, given by the rotation of the concentric tubes about each other, thus resulting in the detachment/attachment of clamp with its jaws blocked in its given position at the time of detachment. The clamp retrieving device consisting of a grasping element, attached through an elongated shaft, consisting of concentric sheaths, to a handle, where the push of a plunger, leads to the sliding of some sheaths in relation to the other(s), and subsequent clamp seizing, clamp jaws release, and clamp retrieval from the human body.
