Abstract: A device for shaping and cutting a bone graft comprises a main body (2) extending along a longitudinal axis (X) from a lower end (2i) to an upper end (2s) and having inside it a housing (3) for the insertion of the bone graft (100) to be shaped, an upper opening (4), located at the upper end (2s), for the insertion of the bone graft (100) into the housing (3), a lower support (5) designed to support the bone graft and an upper surface (6) defining a cutting plane, placed at the upper end (2s) and containing said upper opening (4) which is inclined with respect to the longitudinal axis (X) by an angle (a) ranging between 90° and 30°, preferably between 90° and 60°.

Abstract: A retractor for surgery according to various implementations comprises a handle, an operating portion, and a curved body. In a side view, the handle, the curved body, and the operating portion each define a mean line, wherein: the mean line of the curved body extends along an arc, the mean line of the handle is tangent to the arc, the mean line of the operating portion defines a concavity opposed to the concavity of the arc; the operating portion comprises a retraction segment and one rest segment comprising a tip; and the extension of the circular arc intersects the rest segment. In a front view, the curved body defines an opening comprising a proximal portion having width l and a distal portion having width L, wherein l<L.

Abstract: The invention relates to a retractor for shoulder surgery. The retractor comprises a handle, an operating portion, and a curved body. In a side view, the handle, the curved body, and the operating portion each define a mean line, wherein: the mean line of the curved body extends along an arc, the mean line of the handle is tangent to the arc, the mean line of the operating portion defines a concavity opposed to the concavity of the arc; the operating portion comprises a retraction segment and one rest segment comprising a tip; and the extension of the circular arc intersects the rest segment. In a front view, the curved body defines an opening comprising a proximal portion having width 1 and a distal portion having width L, wherein 1<L.
