SIMULATOR FOR MASTERING THE SKILLS OF PERFORMING A PUNCTURE OF AN FORAMEN OVALE OF THE SKULL Russian patent published in 2024 - IPC G09B23/28 

FIELD: medicine; training means.

SUBSTANCE: simulator for mastering the skills of performing a puncture of the foramen ovale in the treatment of trigeminal neuralgia includes a plastic skull with a Gasserian ganglion model, electronic control unit, including a microcontroller and made with the possibility of sound and colour signaling when the puncture needle connected to the electronic control unit contacts with Gasserian ganglion branches and cerebral arteries, model of cerebral arteries made of electrically conductive plastic and connected to electronic control unit, and a replaceable disposable expansion system simulating a Meckel cavity with a cerebrospinal fluid circulation system, consisting of a silicone cylinder connected to a syringe capable of supplying liquid under pressure. Gasserian ganglion model is made of electrically conductive plastic, connected to an electronic control unit and consists of maxillary and mandibular branches and an orbital branch separated by a dielectric element. Plastic skull is printed on 3D printer, coated with a silicone shell to simulate an outer layer of the dura mater, contains silicone models of skin, tongue and floor of oral cavity, movable lower jaw and cavity in form of tube for placement of electronic control unit.

EFFECT: providing training of performing a puncture of a Gasserian ganglion according to a standard Hartel technique for treating trigeminal neuralgia.
