Transcranial fastening device for drainage catheters

Transcranial fastening device for at least one drainage catheter, comprising:

• at least one external body adapted to be inserted inside a transcranial drilling hole, said external body being equipped with at least one passage (P) for said drainage catheter, said passage (P) being equipped with one or more blockers of said drainage catheter adapted to allow a sliding of said drainage catheter through said passage (P) along a first movement direction (M1) and to prevent a sliding of said drainage catheter through said passage (P) along a second movement direction (M2);
• at least one actuator operatively cooperating with said blocker and being adapted to be moved from a first operating position in which said blockers do not allow the sliding of said drainage catheter through said passage (P) along said second movement direction (M2) to a second operating position in which said blockers allow the sliding of said drainage catheter through said passage (P) along said second movement direction (M2),
• wherein said device comprises at least one abutment profile radially arranged around said external body in order to about against an external surface of a skullcap adjacent to said drilling hole,
• wherein said blockers comprise a plurality of unidirectional flexible wings radially arranged around said passage (P) of said external body and suitably oriented in such a way as to offer a flexure in favor of the sliding of said drainage catheter along said first movement direction (M1) through said passage (P) and, without the intervention of said actuator which is in their first operating position, to be stopped dead on an external surface of said drainage catheter to prevent the sliding of said drainage catheter along said second movement direction (M2)
