ANESTHESIA DISPOSABLE STERILE OPHTHALMIC RETROBULBAR/PERIBULBAR/SUB TENON CANNULA-19/21/23/25/27G

About ANESTHESIA DISPOSABLE STERILE OPHTHALMIC RETROBULBAR/PERIBULBAR/SUB TENON CANNULA-19/21/23/25/27G

Anesthesia Disposable Cannula-19g/21g/23g/25g/27g Disposable ophthalmic cannula used for administering local anesthesia.

Anesthesia disposable sterile ophthalmic cannulas are specialized, single-use medical instruments designed to safely deliver local anesthetic agents into the retrobulbar, peribulbar, or sub-Tenon's space around the eye for various ophthalmic surgeries. These techniques provide effective pain control (analgesia) and eye muscle paralysis (akinesia) with varying safety profiles.

Types and CharacteristicsThese cannulas are specifically designed to minimize the risks associated with sharp needles (such as globe perforation or optic nerve damage) by employing blunt tips and specific designs tailored to their intended injection sites.

Anesthesia Type	Injection Site	Cannula/Needle Characteristics	Key Features
Retrobulbar	Into the muscle cone behind the globe	Typically a sharp, 23- or 25-gauge needle, 30-38 mm in length	Provides faster, more complete akinesia but carries a higher risk of rare, serious complications
Peribulbar	Into the extraconal space, around the equator of the eyeball	Usually a sharp needle, shorter than 25 mm	Considered safer than retrobulbar but may require a larger volume of anesthetic and has a slower onset of action
Sub-Tenon's	Into the episcleral space (between the sclera and Tenon's capsule)	Blunt-tipped cannula, often curved or angled, with a spatulated or tri-port tip, e.g., 19G, 21G, or 23G with lengths around 25mm to 35mm	Offers a good balance of safety and efficacy, avoiding sharp needle-related risks; the blunt design minimizes tissue trauma

Versatile Gauge Selection For All Needs

With options ranging from 19G to 27G, clinicians can select the most appropriate gauge for each type of ophthalmic regional anesthesia. The varied lengths and diameters facilitate flexibility and optimal performance during retrobulbar, peribulbar, and sub-Tenon procedures, catering to diverse anatomical and procedural requirements.


Precision Engineering for Patient Comfort

Every cannula is constructed using high-grade stainless steel and flexible PVC, complemented by a meticulously rounded blunt tip that helps minimize trauma to delicate ocular tissues. The Luer lock connector ensures secure and convenient syringe attachment, contributing to a smoother, safer injection process.


Sterility and Safety Assured

Each cannula is individually blister-packed and EO gas sterilized, ensuring maximum sterility right up to the point of use. They are latex-free, reducing the risk of allergic reactions, and are disposable, eliminating the need for reprocessing, and enhancing patient safety in clinical environments.
