Device for fixing a craniotomy operculum to the cranial vault to be inserted in the craniotomy cut

Abstract

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 onlya minimum disconnection of the dura mater (19), reducing to a minimum the danger of bleeding.

Description

technical field [0001] The present invention relates to a device for stably securing a craniotomy aperture to the cranial cranium to be placed along a craniotomy incision. Background technique [0002] A craniotomy is a surgical intervention to open the skull by cutting open and cutting the top of the skull. Craniotomy is a mandatory procedure for any intracranial surgical intervention. [0003] The open cranial procedure used to perform subdural surgery provides means to cut the skin and subcutaneous portion with a surgical knife. After the bone is exposed, the periosteum is cut with an electric surgical scalpel, and the periosteum is separated from the bone with appropriate instruments. After the bone is sufficiently exposed, one or more holes are drilled with a special drill. After separating the meninges (menino) below the burr hole, an instrument called a craniotomy is used by which a free bony limb is created that fully exposes the underlying dura (meninx). [0004...

AI Technical Summary

Problems solved by technology

[0011] The devices of the prior art, although allowing optimal fastening of the craniotomy ostium, are inconvenient because of the burden of the lower base which must be inserted in the epidural space between the dura mater and the parietal bone, This involves separating the excess of the epidural space between the dura mater and the cranial roof, a delicate procedure that means a high risk of bleeding

On the other hand, assembling the device without the use of the lower base, while possible, presents inconveniences because the shape of the elongated elastic arms has sharp bits that when inserted into the epidural space Risk of tearing, high risk of bleeding when inserted in the dura mater
