DEVICE FOR CRANIOPLASTY WITH HINGE SPACERS Russian patent published in 2020 - IPC A61B17/80 A61F2/28 

FIELD: medicine.

SUBSTANCE: cranioplasty device includes a plate configured to cover a hole in the skull and having opposite top and bottom surfaces and an edge (perimeter), ring made with possibility of attachment to skull, and group of braces, each having opposite inner and outer ends, attached respectively to plate and to ring and installed with possibility of plate movement between raised (upper) position above skull and lowered (lower) position, in which plate is connected to skull. Method of protecting the brain after removing part of the skull to form a hole in the skull involves attachment to the skull of the ring so that it covers the entire contour of the made hole, wherein the ring has an adjustable plate located above the opening in the skull and spaced at a given distance from the brain, and lowering the plate relative to the ring as the brain tumor decreases. Adjustable device for cranioplasty after craniotomy, in which a hole is made in the skull for exposing part of the brain, includes a ring, made with possibility of attachment to skull around hole with its full coverage, plate connected to ring, installed with possibility of movement between raised (upper) position above ring and lowered (lower) position flush with ring. Device for cranioplasty includes a plate covering a hole in the skull, three fastening assemblies, which are fixed on the skull next to the hole made in it; three assemblies of braces forming tripod, outer ends of which are connected to fastening assemblies, and inner convergent in vertex with possibility of retraction, and plate, which has peripheral edge with tapered petals for smoothing transition between plate and skull when plate is lowered from lifted above skull position in lower position, closing with skull.

EFFECT: invention provides cerebral decompression with reduction of intracranial pressure and simultaneous creation of a solid protective coating above a hole in the cranium during a surgical operation.
