8 ¼” Penfield Dissector MRI Compatible – No. 4 Single-Ended

8 1/4″ Penfield Dissector MRI Compatible – No. 4 Single-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 a single-ended No. 4 Penfield tip, the dissector enables precise separation of tissue planes and controlled handling of delicate neural structures while helping minimize tissue trauma. The slender shaft and balanced design provide excellent maneuverability and tactile feedback, supporting accurate dissection in confined operative fields. With an overall length of 8 1/4 inches (approximately 21 cm), the instrument offers an ideal balance of reach and precision for neurosurgical applications. The ergonomic 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 Specifications Feature Details Product Name 8 1/4″ Penfield Dissector MRI Compatible – No. 4 Single-Ended Instrument Type Neurosurgical Dissector Function Tissue Dissection and Periosteal Elevation Overall Length 8 1/4 in (approximately 21 cm) Tip Configuration Single Ended Tip Size No. 4 Compatibility MRI Compatible Handle Design Ergonomic Handle Application Neurosurgery and Spinal Surgery Material MRI-Compatible Non-Ferromagnetic Alloy Finish Satin Low-Glare Finish Sterilization Fully Sterilizable and Autoclavable Reusability Reusable Performance Precise Tissue Manipulation and MRI-Safe Operation Frequently Asked Questions What is the 8 1/4″ Penfield Dissector MRI Compatible – No. 4 Single-Ended used for?
