Multifunctional plate for neurological cranial surgeries

摘要

A plate used in neurological cranial surgeries having a set of grooves and holes providing it with multiple functions: radial groove with semicircular end sufficient to receive a drain or catheter; central round hole, sufficient to receive a second drain or catheter; three curved oblong holes around the central circular hole and the borders with ends adjacent to the semicircular end of the radial groove. The plate provides a useful area, on which the following are disposed: the semicircular end of the radial groove, the central round hole and the curved oblong.

主权项

1. A plate with multiple functions for neurological cranial surgeries comprising a circular Titanium plate body provided with peripheral holes which are receptors of Titanium micro screws for fixation in the cranium in order to attach the plate body to the skull, said plate having a set of grooves and holes that provide passages which assign multiple functions to the plate,
a radial slot with a semicircular end sufficient to receive a first drain or catheter; a central circular hole, sufficient to receive a second drain or catheter; three curved oblong holes arranged around the central circular hole; said plate provides one per area of use in which the semicircular end of the radial slot, the central circular hole and the curved oblong holes; the said radial slot, the central circular hole and the curved oblong holes are arranged and have configurations and are arranged to provide transcutaneous access of the intracranial cavity via surgical instruments; the radial slot, the central circular hole and the curved oblong holes have dimensions selected to perform its functions and to define between themselves and between themselves and the edge of the plate strips of material sized to help to give rigidity to the plate; wherein the area provided by the central circular hole, the three curved oblong holes and the end semicircular radial slot defines the area of use for transcutaneous and immediate access to intracranial cavity through a puncture or biopsy needle and, said radial slot, the central circular hole and the curved oblong holes having settings and are arranged to enable the surgical instruments to achieve, in a cross shape or angled shape, recurrence pathologies, which need to be treated/drained again in recent or late postoperative; the said area of use acts to allow better reading of Ultrasound waves by locating/being in correspondence of the site in the skull in which there is practically no bone strength.
