7 ¾” Penfield Dissector MRI Compatible – No. 3 Double-Ended

7 3/4″ Penfield Dissector MRI Compatible – No. 3 Double-Ended is a precision neurosurgical instrument commonly used by neurosurgeons, spine surgeons, and interventional specialists during cranial and spinal procedures.

The instrument is specifically designed for blunt tissue dissection, periosteal elevation, and atraumatic manipulation of neural structures during MRI-guided and standard surgical interventions. Its MRI-compatible construction allows safe use in magnetic resonance imaging environments without interfering with imaging quality.

Featuring double-ended No. 3 Penfield working tips, the dissector enables precise separation of tissue planes and controlled handling of delicate neural tissues while helping minimize tissue trauma. The dual-ended design increases versatility and allows multiple dissection functions without changing instruments.

With an overall length of 7 3/4 inches (approximately 20 cm), the instrument offers an ideal balance of reach, maneuverability, and tactile feedback for neurosurgical applications.

The ergonomic central handle provides a secure grip and enhanced control during microsurgical procedures.

Manufactured from MRI-compatible, non-ferromagnetic surgical-grade materials, the dissector delivers excellent durability, corrosion resistance, and dependable long-term performance. The satin low-glare finish minimizes reflections under surgical lighting and facilitates efficient cleaning and maintenance.

Fully reusable and autoclavable, this instrument is designed to withstand repeated sterilization cycles while maintaining structural integrity and consistent performance.

Common Clinical Applications Include:

• MRI-Guided Neurosurgery
• Cranial Surgery
• Spinal Surgery
• Periosteal Elevation
• Neural Tissue Manipulation
• Blunt Tissue Dissection
• Skull Base Surgery
• Microsurgical Procedures
• Image-Guided Interventions
• Educational and Training Applications
