Abstract
A surgical drill (1), comprising a rotating head (2) having a drill bit (3) suitable to bore a body (4) and support means (7) to which the head (2) is pivotally connected. An actuating unit (10) of the movement of the drill bit (3) with respect to the body to bore (4) is provided for, comprising a first support (11) comprising the head (2) and a second support (12), suitable for resting directly upon the body (4) and translating with respect to the first support (11) parallel to the drill bit (3). The movement between drill bit (3) and body (4) is caused by the relative movement between drill bit (3) and second support (12). Means (21) for the detection of the force acting on the drill bit and means for the control of the drill bit displacement in function of the drilling force are provided for. The drill, manually holdable, presents both a reference with respect to the patient body and allows a precise control of the drill bit displacement.
