The Penfield Dissector #4 11″ Neurosurgical Dissector for Deep Access is a specialized surgical instrument engineered to provide exceptional precision and control during neurosurgical, spinal, and microsurgical procedures that require extended reach. Designed for deep operative fields, this instrument enables surgeons to perform delicate tissue dissection, periosteal elevation, and soft tissue manipulation while maintaining excellent visibility and control. Its extended 11-inch length makes it particularly valuable in complex cranial and spinal surgeries where conventional-length instruments may not provide sufficient access.

The instrument features the classic Penfield No. 4 working tip, carefully designed for atraumatic tissue handling and precise anatomical dissection. The finely crafted tip allows surgeons to elevate periosteum, separate soft tissue planes, mobilize neural structures, and expose critical anatomical landmarks with minimal disruption to surrounding tissues. Its rounded profile provides excellent tactile feedback, allowing controlled movements around delicate nerves, blood vessels, and connective tissues while reducing the risk of unnecessary tissue trauma.

The extended overall length of 11 inches offers superior reach into deep surgical corridors without compromising precision or maneuverability. This additional length allows surgeons to comfortably access difficult anatomical regions during cranial, skull base, and spinal procedures while maintaining ergonomic hand positioning outside the operative field. The design is especially beneficial when working under surgical microscopes or magnification systems, where long instruments are often required to reach deep structures without obstructing visualization.

Manufactured from premium surgical-grade stainless steel, the Penfield Dissector #4 offers exceptional strength, corrosion resistance, and long-term reliability. It is designed to withstand repeated autoclave sterilization cycles while preserving its precise working profile and structural integrity. The satin anti-glare finish minimizes reflections from operating room lighting and microscopic illumination, improving visibility and allowing surgeons to focus on delicate surgical anatomy throughout the procedure.

The ergonomic handle is carefully balanced to provide maximum comfort and superior instrument control during prolonged operations. Its lightweight construction reduces hand fatigue while enhancing tactile sensitivity and responsiveness. The well-balanced design allows smooth, controlled movements during deep dissections, enabling surgeons to perform intricate procedures with greater confidence and precision even in confined operative spaces.

The Penfield Dissector #4 11″ is widely used in neurosurgery, spinal surgery, orthopedic spine surgery, skull base surgery, and advanced microsurgical procedures. It is particularly effective during craniotomies, spinal decompressions, tumor resections, cranial nerve surgeries, and other operations requiring deep access and meticulous tissue handling. Its combination of extended reach, precision craftsmanship, and ergonomic performance makes it an essential instrument in modern neurosurgical practice.

Trusted by neurosurgeons and surgical specialists worldwide, the Penfield Dissector #4 11″ delivers consistent performance in demanding clinical environments. Whether used for tissue dissection, periosteal elevation, anatomical exploration, or neural tissue manipulation, this instrument provides the accuracy, durability, and reliability required for today’s most complex surgical procedures.
