Abstract

Dispositivo per manipolare viti pedicolari, la cui testa anulare su lati contrapposti presenta superfici di serraggio parallele per l'accoppiamento con almeno un dispositivo di fissaggio presentante due perni filettati, caratterizzato dal fatto che è prevista una bocca rigida (48, 48b, 48c) a forma di forcella, che presenta un perno (42, 60), il quale è diretto nell'interno della bocca e può essere portato ad impegnarsi con vincolo geometrico con una rientranza (44) della testa (14) della vite pedicolare (12) (Figura 1).Device for manipulating pedicle screws, whose annular head on opposite sides has parallel clamping surfaces for coupling with at least one fixing device having two threaded pins, characterized in that a rigid mouth (48, 48b, 48c) is provided fork shape, which has a pin (42, 60), which is directed inside the mouth and can be brought to engage with a geometric constraint with a recess (44) of the head (14) of the pedicle screw (12) ( Figure 1).
