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.
