The Dermatology & Holloware Jannetta Knife – Small Angled is a specialized microsurgical instrument designed for precise dissection and controlled tissue manipulation during delicate neurosurgical procedures. Its compact angled configuration allows the surgeon to approach specific anatomical structures while maintaining a controlled working position.
The instrument features a small angled working end, providing a defined approach for microsurgical dissection. This configuration can be particularly useful when working in narrow or confined operative areas where a straight instrument may not provide the desired access or angle.
The Jannetta knife is associated with microsurgical neurosurgical techniques, particularly procedures requiring careful tissue separation and manipulation around delicate anatomical structures. Its specialized design supports controlled movements under magnification.
The compact working end is intended for precision rather than broad tissue cutting. The surgeon can use the angled tip to approach the target area while maintaining appropriate visualization through the operating microscope.
A surgical-grade stainless-steel construction is commonly used for reusable microsurgical instruments, providing durability, corrosion resistance, and compatibility with appropriate sterilization processes. The fine working edge should be protected from impact and inspected before every procedure to ensure proper alignment and integrity.
The small angled configuration can be valuable in procedures where instrument geometry is important for accessing difficult-to-reach areas. Proper selection of the angle and size should be based on the surgeon’s technique, operative anatomy, and manufacturer’s specifications.
The Jannetta Knife may be included in neurosurgical, skull-base, microvascular decompression, and specialized microsurgical instrument sets, depending on the exact design and intended use.
As with all microsurgical instruments, careful handling is essential. Reusable instruments should be cleaned, inspected, sterilized, and maintained according to the manufacturer’s validated reprocessing instructions. The instrument should only be used by appropriately trained surgical professionals.
Exact dimensions, blade geometry, handle style, and material specifications may vary between manufacturers. Customers should confirm the exact configuration before ordering.
