Definitions
- the present invention relates to the field of cranial surgery.
- Various solutions are known in the state of the art for plugging trephination holes made in the cranial box.
- European patent EP 510 390 describes a plate intended to cover a hole in a cranial vault in the context of the fixation of a cranial bony cover, characterized by several wings extending radially with respect to a center, separated by slits and at least a part of which has on its outer circumferential segments a hole intended to accommodate an osteosynthesis screw, and by holes provided in the internal segment and in the wings of the plate so that blood and lymph can s '' drain freely after the intervention.
- Another European patent EP 291 632 describes a wafer for small bone surgery, in particular for the treatment of fractures of the bones of the skull and of the face or the like, comprising flanges for screw holes receiving bone screws, and thinned spacers which are located between the edges of the screw holes, at least part of the spacers having a section whose area is less than or equal to twice the area of the section of the flange for the screw hole, and the bars connecting in an arc to the flanges for screw holes, characterized in that, for a center to center distance of the flanges for screw holes from 3.5 to 5 mm, a spacer width from 0.4 to 1.5 mm and a thickness from 0.4 to 0.7 mm, the radius of the transition between 1 spacer and the flange for screw hole is less than or equal to 0.3 to 0.5 mm.
- Another patent EP 205 512 describes a closure made of a surgical material for closing defects or holes in a bone and / or a medullary cavity, which is produced so that it has such a shape and / or so that it is formed of a material so that it adapts to the dimensions of the defects or holes of the bone and / or to the dimensions of the medullary cavity and so that by this the defects or holes of the bone and / or the medullary cavity can be sealed in a pressure-tight manner with respect to the internal pressure of the bone canals and / or of the medullary cavity.
- a solution which consists of plugging the hole with a plug of grease, then sewing up the scalp. Such a solution, if it effectively allows not to create an overpressure in the cranial box, nevertheless does not avoid the risks of perforation.
- the present invention provides a device which makes it possible to close the holes made, in order to avoid the problems of perforation, but not to seal the said holes in a sealed manner, so as not to cause overpressure. harmful inside the cranium.
- the present invention relates, in its broadest sense, to a surgical device for closing a substantially cylindrical hole made in the skull, characterized in that it is constituted by a cylindrical stud made of a material biocompatible having two superimposed cylindrical parts of different section, the diameter of the first cylindrical part being less than the diameter of the hole and the diameter of the second cylindrical part being greater than the diameter of the hole.
- the device makes it possible to balance the pressures between the inside and the outside of the cranial box, while closing it, thus avoiding bad scarring, the entry-exit of undesirable materials.
- the stud is constituted by a first cylindrical part having a section of approximately 13 millimeters.
- the stud is constituted by a second cylindrical part having a section of approximately 18 millimeters.
- the stud is made of a woven or nonwoven synthetic material.
- the second cylindrical part has a straight lower edge and a rounded upper edge.
- the pad according to the invention is constituted as a plug of a woven or nonwoven synthetic material with two stages.
- the first stage making the first cylindrical part (1) has a section of 13 millimeters. It is intended to be housed in a substantially cylindrical cavity, having a diameter of 14 millimeters, produced in the cranial box for example by trepanation.
- the second stage making the second cylindrical part (2) has a section of 18 millimeters.
- the cylindrical parts (1 and 2) are coaxial.
- the lower edge (3) of the second cylindrical part (2) is intended to cooperate with the external surface of the bone of the cranial box and allow support on this surface.
- the lower edge (3) is preferably straight.
- the second cylindrical part (2) has a rounded upper edge (4), in order to facilitate the insertion of the device under the skin.
