摘要：
Instrument (9) for removing a bone insert, for example for a shoulder prosthesis, comprising: - a rod-like body (40) that extends along a longitudinal axis (xx) and is provided with a proximal grip (19)； - a distal operation head (15), which is slidably associated with the rod type body (40) so that both can approach and move away from each other； - a cutting element (30) within said operating head (15)； and - a terminal tip (16) protruding coaxially from said operating head (15), - a pushing mechanism (8), inserted into said operating head (15) and acting on said cutting element (30) , in order to move it angularly from a rest position, in which it is housed hidden inside said end tip (16), to an operative position in which it protrudes cantilever through a side opening (27) located in the terminal tip； said cutting element (30) having a blade (31) extending in a direction substantially transverse to said longitudinal axis (x-x), when it is in the operative position； the instrument (9) being characterized in that - between the operating head (15) and the rod (40) an elastic element (34) is provided to steadily deflect the operating head (15) and the rod (40) and away from each other, and to deflect said cutting element (30) towards said resting position.Instrumento (9) para extirpar un inserto óseo, por ejemplo para una prótesis de hombro, que comprende: - un cuerpo de tipo vástago (40) que se extiende a lo largo de un eje longitudinal (x-x) y está provisto de un agarre proximal (19)； - un cabezal de operación distal (15), que está asociado de manera deslizante con el cuerpo de tipo vástago (40) para que ambos puedan acercarse y alejarse entre sí； - un elemento de corte (30) dentro de dicho cabezal de operación (15)； y - una punta terminal (16) que sobresale coaxialmente desde dicho cabezal de operación (15), - un mecanismo de empuje (8), insertado dentro de dicho cabezal de operación (15) y que actúa sobre dicho elemento (30) de corte, a fin de desplazarlo angular
