Abstract: The invention relates to a surgical device for minimally invasive surgery, comprising a shaft and a surgical module mounted to the distal end thereof. The shaft includes a tube and a pair of sliders driven by the tube via a rotary to linear linkage such that a rotation of the tube around the longitudinal axis induces a movement of the sliders along the longitudinal axis, in mutually opposite directions. The surgical device further includes wires that are each connected to a corresponding slider and to the surgical module such that a movement of the sliders, in mutually opposite directions, induces a movement of the surgical module in a first degree of freedom. The tube is also axially moveable towards the proximal end of the shaft inducing a movement of both sliders away from the surgical module, thereby inducing a movement of the surgical module in a second degree of freedom.

Abstract: The invention relates to a surgical device for minimally invasive surgery. The surgical device comprises a shaft (10) extending along a longitudinal axis to a distal end thereof, and a surgical module (3) mounted to the distal end of the shaft and provided with a movable surgical element. The shaft includes a tube (7) that is rotatable relative to the shaft (10) and a further tube (5). The shaft further includes at least one slider (15A,B) connected to the surgical module and operatively driven by the rotatable tube via a rotary to linear linkage such that a rotation of the rotatable tube around the longitudinal axis induces a movement of the slider along the longitudinal axis thereby inducing a movement of the movable surgical element. The further tube is coaxial with the rotatable tube and rotationally stationary relative to the shaft. Further, the at least one slider is rotationally locked relative to the stationary tube.
