Irrigation/Aspiration Titanium 21gauge 1pair

Intended Use/Discipline : Ophthalmology Instrument : Irrigation/Aspiration Titanium 21gauge Material : Titanium The Titanium 21-Gauge Irrigation/Aspiration (I/A) Handpiece is a high-performance, dual-channel microsurgical instrument designed for the precise and efficient removal of lens cortex and viscoelastic material during the final stages of cataract surgery (primarily phacoemulsification and extracapsular extraction). Its core function is to provide simultaneous, controlled irrigation and aspiration within the confined space of the anterior chamber and capsular bag. The handpiece integrates two independent coaxial lumens: an outer irrigation sleeve that delivers a balanced salt solution (BSS) to maintain chamber stability and an inner aspiration cannula that applies vacuum to draw in and remove soft lens matter. The 21-gauge measurement (approximately 0.72mm outer diameter) specifically refers to the size of the aspiration port/needle, defining its flow characteristics and suitability for fine cortical material. The use of medical-grade titanium as the primary material offers distinct advantages: it is exceptionally strong yet lightweight, reducing hand fatigue during delicate maneuvers. Titanium is also highly biocompatible, corrosion-resistant, and non-magnetic, ensuring long-term durability and safety. The 21-gauge tip represents a fine-to-moderate caliber, offering an optimal balance—it provides sufficient aspiration flow and occlusion capability for efficient cortex removal while minimizing the risk of snagging or rupturing the delicate posterior capsule compared to larger-bore tips. The handpiece typically features an ergonomic pencil-grip design with a lightweight, knurled barrel for precise control. It connects via tubing to the phacoemulsification console, which governs the parameters of irrigation pressure, aspiration vacuum, and flow rate. Surgeons use this instrument to polish the capsular bag, ensuring no residual lens epithelial cells remain that could later proliferate and cause posterior capsule opacification (PCO). This instrument is a critical component of modern cataract surgery sets, valued for its precision engineering, reliable performance, and the material benefits of titanium, which contribute to both procedural safety and instrument longevity. The 21-gauge size is a versatile standard for routine cortical cleanup.

• Separate irrigation and aspiration handpieces for precise control during cataract surgery.
• Removal of lens cortex and epinucleus after phacoemulsification.
• Useful in other delicate ophthalmic surgeries.
• Independent irrigation and aspiration improve surgical precision.
• Smaller gauge (21G) minimizes incision size and trauma.
• High-quality materials ensure longevity with proper care.
• Can be sterilized at high temperatures (typically up to 135°C).
• Regular checks for tip integrity and smooth operation.
