Clinical Application
Designed for controlled percutaneous access to the maxillary antrum (antral cavity), this instrument is used in ENT procedures for diagnostic aspiration, antral irrigation/lavage, delivery of topical agents, and relief of acute maxillary sinus collections. The 2.5 mm diameter provides a balance between adequate lumen for aspiration/irrigation and a minimally traumatic entry profile for both office-based and operating-room interventions.
Design & Configuration
The device consists of a slender cannula used in conjunction with a pointed trocar/obturator to achieve initial access. A sharp trocar point facilitates precise puncture of the antral wall with controlled penetration depth and tactile feedback. Once the cannula is positioned, the obturator is removed to permit suction, irrigation, or instillation through the cannula lumen. The slim 2.5 mm profile minimizes soft-tissue disruption and is well suited for delicate sinonasal anatomy.
