The Healon Injection Cannula 21G is a specialized ophthalmic microsurgical instrument designed for controlled delivery of compatible ophthalmic viscoelastic solutions. With a 21-gauge profile, this cannula is suitable for delicate eye-surgery applications where precise fluid or viscoelastic delivery is required.
The cannula is particularly associated with injection applications involving compatible ophthalmic viscoelastic products, including products identified by the Healon name. However, compatibility should always be confirmed with the specific solution, syringe, and delivery system before use. Product labeling and the applicable clinical protocol should determine the intended application.
The 21G gauge provides a fine working profile while maintaining a practical internal pathway for controlled delivery. This makes the cannula a useful component of specialized ophthalmic microsurgical instrument sets and fluid-delivery systems. The exact tip configuration, working length, and connection design may vary depending on the manufacturer or product version and should be verified from the applicable specifications.
Designed for ophthalmic use, the cannula can support organized and precise handling during compatible microsurgical applications. Its compact construction makes it suitable for inclusion with other injection cannulas, irrigation instruments, and ophthalmic accessories in surgical trays.
Before use, the cannula should be inspected for visible damage, deformation, contamination, or obstruction of the internal lumen. Particular care should be taken with the working end and connection point to help maintain a clear delivery pathway. Compatibility between the cannula, syringe, solution, and any associated components should be confirmed before use.
The Healon Injection Cannula 21G is intended for trained ophthalmic professionals and should be used only in applications supported by the applicable product labeling and clinical protocol. It is not intended to replace manufacturer-specific instructions for the handling or delivery of ophthalmic viscoelastic products.
The instrument is manufactured from appropriate surgical-grade instrument material for dependable handling and durability when properly maintained. Exact material composition should be confirmed from the manufacturer’s documentation rather than assumed from the product pattern or name.
Depending on the specific configuration and labeling, the cannula may be supplied as a reusable or single-use instrument. Reusable versions should be cleaned, disinfected, and sterilized according to validated manufacturer instructions and the healthcare facility’s established reprocessing protocol.
With its 21G fine profile and injection-focused design, the Healon Injection Cannula provides a practical option for controlled delivery of compatible ophthalmic solutions in microsurgical applications.

FAQs
What is the Healon Injection Cannula 21G used for?
It is designed for controlled injection of compatible ophthalmic viscoelastic solutions during appropriate microsurgical applications.
What does 21G mean?
21G refers to the cannula gauge and indicates its fine working profile and lumen size classification.
Is this cannula specifically for Healon?
The name identifies its intended association with Healon-type ophthalmic viscoelastic delivery, but compatibility should always be confirmed with the specific product and delivery system.
Can it be connected to a syringe?
Yes, when the cannula connection is compatible with the selected syringe or injection system.
Is the 21G cannula reusable?
Reusability depends on the specific product configuration and manufacturer labeling. Reusable versions require validated cleaning and sterilization procedures.
How should the cannula be maintained?
Inspect the working end and internal lumen for damage or blockage and follow validated manufacturer instructions for cleaning, sterilization, and storage.
Can it be included in an ophthalmic instrument set?
Yes. It can be included in compatible ophthalmic microsurgical sets requiring a 21G injection cannula for controlled delivery of appropriate solutions.
