The Weil Lachrymal Cannula 21 Gauge Blunt Tip is a specialized ophthalmic microsurgical instrument designed for controlled fluid delivery in lacrimal and related eye procedures. Its Weil pattern, 21 gauge specification, and blunt-tip configuration make it suitable for professional ophthalmic instrument sets where controlled irrigation or fluid administration is required.
The 21G profile provides a defined cannula diameter for fluid delivery while maintaining a practical size for delicate ophthalmic applications. The blunt tip is designed to provide a non-sharp working end, making this configuration appropriate for procedures where a blunt cannula is preferred according to established clinical technique. Exact clinical use should be determined by the qualified clinician based on the procedure and instrument configuration.
Lachrymal cannulas are used in ophthalmic procedures involving the lacrimal drainage system and may support controlled irrigation or introduction of compatible fluids. The Weil Lachrymal Cannula can be connected to an appropriate syringe, tubing, or irrigation system when the connection is compatible. Before use, the connection should be checked for secure attachment and suitability for the intended application.
The blunt tip and compact cannula profile allow the instrument to be handled carefully in the delicate environment of ophthalmic procedures. The cannula should be manipulated according to established clinical protocols, with appropriate attention to the anatomy involved and the intended procedure. This product is intended for use by trained healthcare professionals in suitable clinical settings.
For reusable configurations, proper cleaning and inspection are important for maintaining the cannula’s function and preventing contamination. Particular attention should be given to the internal lumen, which should be checked for obstruction and cleaned according to validated reprocessing procedures. The cannula should also be inspected for bending, surface damage, deformation, or other abnormalities before reuse.
The Weil Lachrymal Cannula 21G Blunt Tip can be included in specialized ophthalmic, lacrimal, and microsurgical instrument sets. Its 21G specification provides a practical fluid-delivery profile, while the blunt tip offers a controlled working configuration for procedures requiring this type of cannula.
Material construction should be verified according to the specific product supplied. Surgical-grade instrument materials are typically selected for their durability and suitability for professional medical environments. Where the product is reusable, cleaning, disinfection, sterilization, storage, and handling should follow the manufacturer’s validated instructions and the healthcare facility’s approved protocols.
If supplied as a single-use product, it should be used only as labeled and should not be reprocessed or reused unless specifically permitted by the manufacturer and applicable regulations. Proper sterile handling should be maintained throughout clinical use.
The Weil Lachrymal Cannula 21 Gauge Blunt Tip is a practical precision instrument for ophthalmic professionals seeking a dedicated blunt-tip cannula for controlled lacrimal fluid delivery applications.
