摘要：
A device (100) for implanting a surgical screw (2), comprising an outer sleeve (3) with a hollow interior and an inner sleeve (4) with a hollow interior, suitable for axial and sliding engagement, said outer sleeve comprising (3) an outer central body (303), an outer proximal terminal part (301), an outer distal terminal part (302), integrally connected to each other, at least one outer channel (304, 305) extending to everything along the outer proximal end portion (301) and along a substantial portion of the outer core body (303), said inner sleeve (4) comprising an inner core body (403), an inner proximal end portion (401), a inner distal end portion (402), integrally connected to each other, at least one inner channel (404, 405) extending along the entire inner proximal end portion (401) and along a substantial part of the inner core body (403 ), said inner proximal terminal part (401) being divided into two terminal portions (411, 421) by said at least one inner channel (405)； said inner bushing (4) comprising, in the inner proximal part (401) thereof, at least one side coupling element (412, 422) and at least one axial coupling element (417.1, 417.2, 417.3, 417.4) for engaging detachably with a surgical screw (2), characterized in that said lateral coupling device (412, 422) is formed from the inner proximal part (401), cutting and bending it outwards a part of one of said two outer surfaces of the terminal portion (411, 421), and is integrally connected thereto only by means of its upper side (412.3), while its three remaining sides protrude radially from said terminal portion (411, 421) and a substantial part of its length.Un dispositivo (100) para implantar un tornillo quirúrgico (2), que comprende un casquillo exterior (3) con un interior hueco y un casquillo interior (4) con un interior hueco, adecuado para su acoplamiento axial y deslizante, comprendiendo dicho casquillo exterior (3) un cuerpo central exterior (303), una parte terminal proximal exterior (
