Device to fix a cranial limb to the cranial crown to be placed in the hole or craniotomy cut

摘要

Device (10) for attaching a cranial limb to a cranial crown (17) that adapts to be placed both in a craniotomy hole and in a craniotomy cut, comprising: - at least one cortical support elevator (12); - first closing means (11, 13) that are operatively connected to said cortical elevator (12); - second closing means (14) adapted to be fixed to said cortical elevator (12) to complete its closing; - at least one handle (15) that removably connects to said cortical elevator (12) and is adapted to drive said device (10) to bring it from its resting position to its operative holding position; wherein said first closing means (11, 13) that are connected to a distal end of the cortical elevator (12) and said second closing means (14) are adapted to be attached to the cortical elevator (12) in a position close to the distal end of the cortical elevator (12), so that when the device (10) is in its operative fixation position, said first closing means (11, 13) are placed against the internal distal cranial surface and said second means ( 14) of closure are placed against the outer surface close to the skull, said first closure means (11, 13) being composed of at least two elongated elastic arms (11) that are operatively connected to said cortical elevator (12), terminating each one of said elongated elastic arms (11) in at least one small elongated arm (13) that is positioned transversely with respect to said elongated elastic arms (11). characterized in that said device (10) is further equipped with at least one lower base (5) to be assembled with the device (10) to hold a cranial limb and to simultaneously close the holes obtained to perform the craniotomy, said base having ( 5) lower a cut (6) through which said device (10) passes when said device (10) moves to its operative fixation position, and a seat (7) where said transverse arms (13) are housed and slid small attached to said elastic arms (11).
