The Penfield Dissector, MRI Safe, No. 4, Single Ended, 8 1/4 is a precision-engineered neurosurgical instrument designed for controlled and atraumatic dissection of soft tissues in delicate surgical procedures. It is widely used in neurosurgery, spine surgery, and other procedures where precise tissue separation and safe handling of neural structures are essential. This instrument is constructed with MRI safe materials, making it suitable for use in environments where magnetic resonance imaging compatibility is required. Its non-ferromagnetic properties reduce interference risk, allowing safer handling in imaging-related surgical workflows. The instrument features a No. 4 Penfield tip, designed for fine and controlled dissection. This tip allows surgeons to gently separate tissue planes, retract delicate structures, and assist in exposing surgical fields with high precision and minimal trauma. The single-ended 8 1/4-inch design provides excellent balance, reach, and maneuverability. It ensures stable handling during deep or confined surgical procedures while maintaining optimal control and accuracy. Manufactured from premium surgical-grade stainless steel (MRI safe alloy), the instrument offers excellent strength, corrosion resistance, and long-term durability. It is designed to withstand repeated sterilization cycles without loss of performance, ensuring reliability in operating rooms and surgical centers. The ergonomically designed handle provides a secure and comfortable grip, allowing surgeons to maintain precision during extended procedures. Its balanced structure reduces hand fatigue and improves surgical efficiency. Fully reusable and autoclavable, the Penfield Dissector MRI Safe No. 4 is an essential instrument for neurosurgeons and spine surgeons performing delicate dissection procedures requiring precision, safety, and MRI compatibility.
