Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable flexible brain expansion surgical channel forming device. Background Art

[0002] Intraventricular hemorrhage is a common, acute, and severe neurological condition. Among them, intraventricular system hemorrhage cast is a common type of ventricular hemorrhage, which can easily lead to acute, severe hydrocephalus and carries a high mortality rate, requiring emergency hematoma evacuation and unblocking of the cerebrospinal fluid circulation pathway. With the advancement of microsurgical techniques, particularly neuroendoscopy, small channels directly accessing the ventricles can clear intraventricular system hemorrhage and alleviate hydrocephalus.

[0003] Chinese utility model patent announcement number: CN221205596U, discloses: a disposable flexible brain expansion surgical channel forming device, the disposable flexible brain expansion surgical channel forming device, by placing a puncture probe between a balloon body in a compressed state and a film, when the expansion balloon assembly reaches the expanded position, inflation pulls the brain tissue into a channel, and then deflates the balloon body to gradually collapse, revealing the channel between the balloon body and the film, and pulls the balloon wall of the balloon body to the other side and folds it to form a channel consisting of half of the balloon wall of the balloon body and half of the film.

After the expander is expanded, the visual probe is taken out of the expander, and the hard pipe is put on the outside of the expander. The expander follows the airbag into the brain tissue, and the air in the expansion airbag is evacuated to restore it to a contracted state and exit the hard pipe to establish a stable hard surgical channel. The channel structure is stable, the operation is more convenient, and the success rate of the operation is improved. The gripping handle is easy to hold and operate. After the hard pipe is deployed, the gas in the airbag is extracted using an external inflation valve and the expander is removed.
