1. Equipment for removing bone cement from bone cavities, comprising an elongated body, hollow inside, that can be inserted inside a cement-filled bone cavity, and at least one extraction rod for extracting said elongated body buried in the cement, that can be inserted inside said elongated body, wherein said elongated body comprises a plurality of rigid elements aligned with each other and associated to one another by the interposition of spacer elements, substantially tubular in shape and coaxial to said elongated body, said rigid elements each including removable means for connecting to said extraction rod which are arranged inside said elongated body, and said spacer elements are comprised of one of an acrylic resin and a bone cement,
wherein at least one of said rigid elements comprises at least one protrusion, protruding crossways to an axis of said elongated body, on which an edge of a distal end of one of said spacer elements at least partially rests, wherein said crossways protrusion comprises a discoidal body, substantially coaxial to said elongated body.
