Claim Text:
1. A minimally invasive surgery instrument, comprising: a. an end tool that is detachable as a retrievable clamp that includes jaws driven by a push-pull rod, the push-pull rod being included within a framework, the end tool being provided with a locking element that is represented by a specific configuration of said push-pull rod that is presenting a segment with symmetrical opposed teeth, an articulation of the push-pull rod that enables said segment of it to revolve around its axis when detaching said end tool from an elongated shaft, thereby gearing said teeth to another set of teeth located on said framework, b. a handle and elongated shaft part that comprises an elongated shaft comprised of concentric tubes and means for revolving said segment around its axis, said elongated shaft being connected to a rotating assembly, that Is attached to a housing inside which a rod is driven by said handle, c. whereby said handle and elongated shaft part transmits a surgeon's commands leading to the actuation of the clamp's jaws by actuating said handle as long as the end tool is attached to said elongated shaft, as well as clamp deployment from the elongated shaft and reattachment to said elongated shaft, by operating on a coupling given by the movement of said concentric tubes in relation to each other, thus resulting in the detachment of said clamp with said jaws locked in their given position at the time of detachment or an attachment of said clamp to said elongated shaft, which leads to ungearing of said teeth.
