Description

Nasal filling support balloon

technical field

The utility model belongs to the technical field of medical devices, in particular to a nasal cavity filling support balloon.

Background technique

Transnasal neuroendoscopic surgery requires the establishment of a surgical pathway through the nasal cavity, and there is no way to suture inside the nasal cavity after surgery. If the patient's postoperative healing is slow, cerebrospinal fluid rhinorrhea will occur. At present, for patients with cerebrospinal fluid rhinorrhea, gauze is used for packing. The gauze is preferably iodoform gauze, because it has good antibacterial properties and can be left for a long time, but the gauze has the following disadvantages:
