Tilley Lichtwitz Antrum Trocar

Clinical Application

Designed to provide controlled access to the maxillary antrum for aspiration, irrigation and drainage. Commonly used during management of maxillary sinusitis, acute empyema of the antrum, or as part of Caldwell‑Luc style procedures to obtain samples, evacuate purulent material, or establish temporary drainage. The instrument is intended to facilitate a single puncture followed by placement of the cannula as a conduit for lavage or suction.

Design & Configuration

The instrument pairs a sharp, pointed obturator (trocar) with a hollow cannula. The trocar provides a focused, controlled puncture through mucosa and bone, while the cannula remains in place to permit aspiration or irrigation without repeated tissue trauma. This separation of functions (penetration vs. conduit) reduces the risk of soft‑tissue shear and allows the operator to exchange suction or irrigation devices through the cannula lumen as needed during the procedure.

Instrument Specifications

• Hollow cannula accepts suction/irrigation through its lumen for lavage and drainage.
• Removable obturator (trocar) with pointed tip for controlled antral entry.
• Designed for intraoral or transcutaneous antral puncture techniques commonly used in otolaryngology.
• Reusable construction suitable for standard sterilization protocols.

Material & Construction

Constructed from surgical‑grade stainless steel to withstand repeated use and standard sterilization cycles. The simple two-piece trocar/cannula design facilitates cleaning and inspection between cases. Reusable construction reduces per‑case costs when instruments are returned to validated cleaning and sterilization workflows.

Quality & Compliance

Manufactured by FDA-registered OEM facilities and produced under strict quality control standards.
