Abstract: A milling tool for prosthetic surgery operations, comprising: a support part with a substantially hemispherical shape; an attachment part able to be associated with the support part in order to allow the selectively releasable connection of a handling device; and a cutting part associated at least with the support part and provided with one or more cutting elements.

Abstract: Milling tool for prosthetic surgery operations, comprising: a support part (21, :32, 57) substantially semi-spherical in shape; an attachment part (24, 33, 68) which can be associated with the support part (21, 32, 57) in order to allow the selectively releasable connection of a manipulator device (28); and a cutting part (81, 82, 83) associated with at least the support part (21, 32, 57) and provided with one or more cutting elements (22).

Abstract: Multilayered bulletproof device including a first layer external during use, provided with a first surface external during use, suitable to receive firearm bullets, a second surface internal during use, a second layer internal during use, disposed facing the second surface of the first layer and defined by a plurality of fibers, where the first layer is made of metal material and the first surface of the first layer is provided with a plurality of protruding portions distributed uniformly, one adjacent to the other, on the first surface.

Abstract: A milling tool for prosthetic surgery operations comprising a cap body, hollow inside, at least a cutting profile, associated with said cap body, and an attachment support positioned and constrained with respect to the cap body and by means of which said cap body can be selectively associated with a relative manual or automatic manipulator.

Abstract: A manipulator device for a milling tool for prosthetic surgery operations, comprising a central body and at least attachment members angularly constrained to the central body to achieve the selective attachment/detachment of the central body to/from the milling tool. The attachment members are provided at one end of the central body and comprise mechanical attachment elements comprising an insertion seating, blind and open toward an insertion end in a direction axial to a median axis of rotation of the central body and at least a groove made radially through to the insertion seating and open toward the insertion end. The attachment members also comprise magnetic attachment elements comprising a magnetic element provided inside the insertion seating, in order to magnetically hold a connection element of the tool inside the insertion seating.
