A surgical device comprising: - a handling member comprising a sleeve with a central slot and a guiding pin that projects radially into said central slot, and - a guiding element configured to be slid into the central slot of said sleeve and that comprises a tubular cylindrical body of elongated shape and extending along a longitudinal axis; said guiding element externally having a guiding groove that is slidably coupled to a guiding pin so that said sleeve and said guiding element are mutually movable along a guiding path defined by said guiding groove; said guiding groove comprising a first and a second rectilinear groove portion, angularly spaced apart about said longitudinal axis, and mutually interconnected by means of a transversal connecting groove portion interposed between said first and said second rectilinear groove portions; wherein the guiding groove extends between a first end portion, defining a grip area of the guiding element, and a second end portion, opposite to the first end portion, configured to be arranged in contact with a bone of a patient; said first rectilinear groove portion extending between the first end portion and the transversal connecting groove portion, and said second rectilinear groove portion extending between the transversal connecting groove portion and the second end portion; said guiding element being translatable along a sliding direction, coinciding with the longitudinal axis, to allow the sliding of the guiding pin along the first and the second rectilinear groove portion, said guiding element being at least partially rotatable about the longitudinal axis thereof in order to allow the sliding of the guiding pin inside the transversal connecting groove portion; wherein said surgical device comprises locking means configured to lock the sliding of the guiding element along the sliding direction inside the central slot, and switchable between an activation configuration, wherein the movement of the guiding element inside said central slot is prevented, and a deactivation configuration, wherein the movement of the guiding element inside said central slot is free; said transversal connecting groove portion being configured to prevent the sliding of the guiding element along said sliding direction during the deactivation configuration of the locking means, when the guiding pin is arranged within said transversal connecting groove portion. - a handling member comprising a sleeve with a central slot and a guiding pin that projects radially into said central slot, and - a guiding element configured to be slid into the central slot of said sleeve and that comprises a tubular cylindrical body of elongated shape and extending along a longitudinal axis; said guiding element externally having a guiding groove that is slidably coupled to a guiding pin so that said sleeve and said guiding element are mutually movable along a guiding path defined by said guiding groove; said guiding groove comprising a first and a second rectilinear groove portion, angularly spaced apart about said longitudinal axis, and mutually interconnected by means of a transversal connecting groove portion interposed between said first and said second rectilinear groove portions; wherein the guiding groove extends between a first end portion, defining a grip area of the guiding element, and a second end portion, opposite to the first end portion, configured to be arranged in contact with a bone of a patient; said first rectilinear groove portion extending between the first end portion and the transversal connecting groove portion, and said second rectilinear groove portion extending between the transversal connecting groove portion and the second end portion; said guiding element being translatable along a sliding direction, coinciding with the longitudinal axis, to allow the sliding of the guiding pin along the first and the second rectilinear groove portion, said guiding element being at least partially rotatable about the longitudinal axis thereof in order to allow the sliding of the guiding pin inside the transversal connecting groove portion; wherein said surgical device comprises locking means configured to lock the sliding of the guiding element along the sliding direction inside the central slot, and switchable between an activation configuration, wherein the movement of the guiding element inside said central slot is prevented, and a deactivation configuration, wherein the movement of the guiding element inside said central slot is free; said transversal connecting groove portion being configured to prevent the sliding of the guiding element along said sliding direction during the deactivation configuration of the locking means, when the guiding pin is arranged within said transversal connecting groove portion.
