Penfield Dissector #4 – 11″

Penfield Dissector #4 – 11″ is a precision neurosurgical instrument commonly used by neurosurgeons, spine surgeons, and orthopedic specialists during delicate surgical procedures involving neural and soft tissue structures. The instrument is specifically designed for blunt tissue dissection, periosteal elevation, and atraumatic manipulation of neural tissues during cranial, spinal, and skull base surgeries. Its double-ended configuration allows surgeons to perform multiple dissection tasks without changing instruments, improving procedural efficiency. Featuring the characteristic Penfield No. 4 working ends, the dissector enables precise separation of tissue planes and controlled handling of delicate neural structures while helping minimize tissue trauma. With an overall length of 11 inches (approximately 28 cm), the instrument provides extended reach for deep operative fields while maintaining excellent maneuverability and tactile feedback. The ergonomic central handle offers a secure grip and enhanced control during microsurgical procedures. Manufactured from premium surgical-grade stainless steel, the Penfield Dissector #4 delivers excellent durability, corrosion resistance, and dependable long-term performance. The satin low-glare finish minimizes reflections under surgical microscopes and operating room lighting while facilitating 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: Cranial Surgery Spinal Surgery Neurosurgical Procedures Periosteal Elevation Neural Tissue Manipulation Skull Base Surgery Blunt Tissue Dissection Microsurgical Procedures Orthopedic Procedures Educational and Training Applications Specifications Feature Details Product Name Penfield Dissector #4 – 11″ Instrument Type Neurosurgical Dissector Function Tissue Dissection and Periosteal Elevation Overall Length 11 in (approximately 28 cm) Tip Configuration Double Ended Tip Size No. 4 Handle Design Ergonomic Central Handle Application Neurosurgery and Spinal Surgery Material Surgical-Grade Stainless Steel Finish Satin Low-Glare Finish Sterilization Fully Sterilizable and Autoclavable Reusability Reusable Performance Precise Tissue Manipulation and Enhanced Control Frequently Asked Questions What is Penfield Dissector #4 – 11″ used for?
