Stainless Steel Vannas Sciss. Sharp Tips Curved/Straigth 85mm Long 5mm bl. (Straight)

Intended Use/Discipline : Ophthalmology Instrument : Vannas Scissors, Vannas Scissors: Curved,Straight Sharp Tips, 85mm Long, 5mm Blades General Overview: The Vannas scissor is a quintessential microsurgical instrument, and this specific configuration represents a highly specialized tool for the most delicate intraocular and micro-dissection tasks. Its compact size, fine curved blades, and extremely sharp tips are engineered for cutting within confined spaces where the slightest imprecision could compromise surgical outcomes. Detailed Specifications & Features: 1. Dimensions and Design: Overall Length: 85 mm (3.3 inches). This short length is designed for work within the eye itself (intraocular surgery) or other extremely confined microsurgical fields, offering maximum stability and control at a microscopic scale. Blade Design: Blade Length: 5 mm. These are very short blades, providing exceptional rigidity and control for sniping rather than long, sweeping cuts. Pattern: Curved. The blades have a fine, gentle curvature, allowing the surgeon to navigate and cut around anatomical structures (like the iris or within the capsule) without obscuring the view. Tip: Sharp. The tips are needle-point sharp, enabling them to easily engage and cut fine tissues and sutures with minimal force. Blade Spring Action: A key characteristic of true Vannas scissors is the spring-action design of the very fine, delicate blades, which provides a smooth, responsive, and controlled cutting feel. 2. Functional Purpose & Advantages: This instrument is designed for precision that standard eye scissors cannot achieve: Intraocular Maneuverability: The 85mm length and 5mm curved blades are perfectly proportioned to enter through a corneal or scleral port and operate inside the anterior or posterior segment of the eye without causing collateral damage. Controlled, Fine Cutting: The design is for "single-strand" cutting of sutures (like 10-0 nylon) and delicate membranes (such as the lens capsule or vitreous strands) without dragging or tearing adjacent tissues. Enhanced Visibility: The curved blade design allows the surgeon to position the scissors around corners and keep the bulky part of the instrument out of the direct line of sight through the operating microscope. 3. Handle and Ergonomics: Handle Design: Typically features rounded, serrated finger rings that facilitate a delicate thumb-ring grip for the highest level of control. Material & Finish: Manufactured from high-grade, corrosion-resistant stainless steel. Often has a satin finish to reduce glare. 4. Primary Applications: This scissor is reserved for high-precision microsurgical procedures: Cataract Surgery: Cutting the anterior lens capsule (Capsulorhexis) in difficult cases. Cutting prolapsed vitreous strands (Vitrectomy). Trimming a fibrosed or opacified capsule. Glaucoma Surgery: Performing a sclerostomy or cutting delicate trabecular meshwork in minimally invasive glaucoma surgery (MIGS). Corneal Surgery: Cutting fine sutures on the corneal surface without scratching the tissue. Vitreoretinal Surgery: Membranectomy, cutting epiretinal membranes or fine vitreous bands. 5. Key Advantages: Ultimate Precision: The combination of short, sharp, curved blades provides unparalleled accuracy for micro-dissection. Minimal Tissue Trauma: Allows for cutting in extremely delicate areas without disturbing the surrounding architecture. Specialized Function: The design is optimized for a specific set of high-skill intraocular maneuvers, making it an essential tool for complex anterior segment and vitreoretinal surgery.

• Ultra-Short Blades (5mm): Provide incredible control for minuscule cuts, allowing the surgeon to work within a field of just a few millimeters.
• Sharp, Curved Tips: The combination allows for precise, controlled dissection and cutting around critical structures (like blood vessels or the lens capsule) with superb visibility over the blades.
• Spring-Handle Design: Enables fine, rotational movements driven directly by the fingertips, minimizing hand tremor and offering superior tactile feedback compared to larger, heavier scissors.
• Fine, Sharp Edges: The blades are honed to an extreme sharpness, enabling them to cleanly cut delicate tissues without crushing or tearing.
• Ideal for Confined Spaces: The small size and curved profile are perfect for intraocular surgery, allowing the tips to maneuver safely within the eye without damaging surrounding structures like the iris or cornea.
• Cataract Surgery: Cutting the anterior lens capsule (capsulotomy).
• Glaucoma Surgery: Performing trabeculectomies and cutting delicate scar tissue.
• Vitreoretinal Surgery: Cutting epiretinal membranes (ERM) or the vitreous strandswithout damaging the retina.
• Neurovascular & Plastic Surgery: For dissecting fine nerves and microvessels.
