Vannas Scissors Westcott Tenotomy Ophthalmic Microsurgical Instruments

Vannas scissors are surgical instruments used in ophthalmic microsurgery procedures. These scissors are specifically designed for delicate and precise operations on the eye, making them an essential tool for ophthalmologists and eye surgeons.

Developed by Dr. Sven Vanna from Sweden, Vannas scissors have become a staple in the field of ophthalmology since their creation in the 1960s. They were initially designed for cataract surgery but have now found uses in various other procedures such as glaucoma surgery, corneal transplantation, retinal detachment repair, and more.

One of the key features of Vannas scissors is their unique design. They have small curved blades that are ideal for making intricate cuts with precision and minimal damage to surrounding tissues. The tips of these scissors are also sharp and pointed, allowing surgeons to work in tight spaces without disrupting delicate structures.

Vannas scissors come in different sizes and angles, each serving its specific purpose during surgery. The most common sizes range from 8mm to 22mm, with angled versions varying from 30 degrees to 70 degrees. This variety allows for customized usage based on the particular needs of each procedure.

Apart from their specialized design, Vannas scissors also stand out due to their high-quality material and construction. They are typically made of medical-grade stainless steel or titanium, ensuring durability and resistance to corrosion after repeated sterilization processes.

The ergonomics of Vannas scissors make them user-friendly for surgeons operating under a microscope or using magnifying loupes. Their handles have a comfortable grip that allows for precise control while performing delicate tasks during surgery. This feature is especially crucial when working on fragile ocular tissue or suturing tiny blood vessels.

In addition to their use in ophthalmic microsurgery procedures, Vannas scissors can also be used outside the field of eye surgery. Their small size and sharp, precise blades make them suitable for procedures in other areas of the body that require delicate cuts, such as plastic surgery and dental surgery.

Vannas scissors are a crucial instrument for every ophthalmologist’s toolkit. They provide exceptional precision and control during delicate eye surgeries and have expanded their application to various other specialized medical fields. With their unique design, high-quality materials, and user-friendly features, they continue to be one of the most preferred surgical instruments for ophthalmic microsurgery.
