Abstract

Surgical device, in particular for minimally invasive surgery, provided with a shaft having a distal end to which a surgical instrument is mounted or mountable and a proximal end equipped for handling the instrument, wherein the shaft is hollow and the surgical instrument is mounted or mountable on inserts that are longitudinally movable in the said shaft parallel to the longitudinal axis of the shaft, which inserts are provided diametrically opposed to each other within said shaft. The shaft comprises an outer tube and an inner tube which are rotatable in opposite directions with respect to the longitudinal axis of the shaft, and the inserts are coupled to the outer tube and the inner tube so as to convert rotational movement of said tubes into longitudinal movement of the inserts.
