Backflush Aspiration Cannula

Backflush Aspiration Cannula is a specialized ophthalmic surgical instrument used for aspiration and controlled backflush fluid delivery during vitreoretinal and posterior segment surgeries. Designed for delicate intraocular manipulation, the instrument incorporates a fine aspiration cannula connected to a compressible silicone reservoir (backflush bulb) that allows surgeons to alternate between aspiration and fluid reflux. This dual-function capability enables precise management of intraocular fluids and tissue during microsurgical procedures. During aspiration, the cannula removes fluid, blood, debris, perfluorocarbon liquids, and other intraocular materials from the surgical field. By gently compressing the silicone bulb, surgeons can generate controlled backflush flow to release or reposition retinal tissue and other delicate structures when necessary. The instrument is widely used in vitreoretinal surgery where controlled aspiration and reflux are essential for safe manipulation of retinal tissue. The backflush function helps minimize unwanted tissue adherence to the cannula tip and facilitates atraumatic tissue handling. Its slim profile and fine atraumatic tip provide excellent access to posterior segment structures while maintaining optimal visualization under the operating microscope. The lightweight design offers superior balance, tactile feedback, and maneuverability during delicate microsurgical procedures. Backflush Aspiration Cannulas are commonly utilized during vitrectomy procedures, retinal detachment repair, membrane peeling, fluid-air exchange, subretinal fluid drainage, vitreoretinal reconstruction, and other posterior segment surgeries. Manufactured from premium surgical-grade stainless steel and medical-grade silicone components, the instrument offers exceptional durability, corrosion resistance, and dependable clinical performance. The smooth internal lumen supports efficient aspiration and controlled fluid dynamics. Available in multiple gauge sizes, shaft lengths, tip configurations, and handle styles, Backflush Aspiration Cannulas can be selected according to surgical technique and surgeon preference. Widely used in hospitals, ophthalmic surgery centers, retinal specialty clinics, and ambulatory surgical facilities, the Backflush Aspiration Cannula is an essential instrument in modern vitreoretinal surgery. Fully reusable and autoclavable, the instrument is designed to withstand repeated cleaning and sterilization cycles while maintaining lumen integrity, aspiration performance, and structural reliability.
