The Air Injection Cannula 19ga Ang 7mm is a specialized ophthalmic microsurgical instrument designed for controlled air delivery during compatible ophthalmic applications. It combines a 19G cannula profile with an angled configuration and a stated 7mm working specification, providing a practical option for ophthalmic instrument sets requiring controlled air delivery.
The angled design provides positioning flexibility compared with a straight cannula, allowing the working end to be oriented according to the intended application. The 7mm specification identifies the stated working dimension of this particular configuration. Exact tip design, connection type, and overall dimensions may vary by manufacturer, so compatibility should be confirmed before use.
The 19G profile provides a larger working diameter than finer 23G, 27G, or 30G cannulas. This makes gauge selection an important consideration when matching the cannula to a compatible air-delivery system and the requirements of the intended ophthalmic application.
This cannula may be connected to compatible syringes, tubing, or air-delivery systems when the connection specifications are appropriate. It can also be incorporated into ophthalmic microsurgical instrument sets. Users should verify the connection, lumen, and system compatibility before clinical use rather than assuming universal compatibility.
The Air Injection Cannula 19G Angled 7mm is designed for professional ophthalmic environments where controlled delivery and precise instrument handling are required. The angled working profile can assist with positioning, while the specified 7mm dimension provides a defined configuration for instrument selection.
Before use, the cannula should be inspected for visible damage, contamination, or obstruction of the lumen. Fine or narrow internal pathways should remain clear to support the intended function of the instrument. Any damaged or compromised instrument should be removed from service according to facility procedures.
Depending on the manufacturer and specific configuration, this cannula may be supplied as a reusable or single-use device. Reusable versions should be cleaned, inspected, disinfected, and sterilized according to validated manufacturer instructions and the healthcare facility’s established reprocessing protocol.
Manufactured from suitable surgical-grade instrument material, the Air Injection Cannula 19G Angled 7mm is intended for use by appropriately trained ophthalmic professionals and should be used in accordance with applicable clinical protocols and device instructions.

FAQs
What is the Air Injection Cannula 19G Angled 7mm used for?
It is designed for controlled air delivery in compatible ophthalmic microsurgical applications.
What does 19G mean?
19G refers to the gauge of the cannula. A 19G cannula has a larger working diameter than finer gauges such as 23G, 27G, or 30G.
What is the benefit of the angled configuration?
The angled design provides additional positioning flexibility compared with a straight cannula, depending on the intended application.
What does 7mm refer to?
The 7mm specification identifies the stated working dimension of this particular cannula configuration.
Can this cannula connect to a syringe?
It can be used with a compatible syringe, tubing, or air-delivery system when the connection specifications match. Compatibility should be verified before use.
Is this cannula reusable?
The use type depends on the specific manufacturer and product labeling. Reusable versions require appropriate validated cleaning and sterilization.
How should the cannula be maintained?
Inspect the working end and lumen before use. Reusable versions should be cleaned and sterilized according to the manufacturer’s instructions and facility reprocessing protocol.
