DEVICE FOR FIXING A CRANIOTOMY OPERCULUM TO THE CRANIAL VAULT TO BE INSERTED IN THE CRANIOTOMY CUT

摘要

A device (10) is described, for stably fixing a craniotomy operculum (18) to the cranial vault (17), to be placed along a craniotomy cut (22), which comprises at least one supporting tensioner (12), to which first (11, 13) and second (14) closing means are operatively connected, respectively placed against the internal distal cranial surface and against the external cranial surface, wherein the first closing means (11, 13) comprise at least two elongated elastic arms (11) which end in at least one small elongated transverse arm (13); the small transverse arm (13) is shaped as a tapered slider, suitable to enable the wedging of the small transverse arm (13) and its following sliding in the epidural space (X) which can be found between cranial vault (17) and dura mater (19), generating only a minimum disconnection of the dura mater (19), reducing to a minimum the danger of bleeding.
