quincke tip spinal needle
The Quincke tip spinal needle represents a fundamental advancement in medical technology, specifically designed for precise spinal anesthesia and diagnostic procedures. This specialized needle features a carefully engineered cutting point with a sharp, beveled edge that creates a clean puncture through the dural membrane. The needle's distinctive design incorporates a medium-length bevel that ensures optimal penetration while minimizing tissue trauma. Available in various gauges typically ranging from 22G to 27G, these needles are manufactured from high-grade stainless steel to maintain structural integrity and ensure patient safety. The Quincke tip's design allows practitioners to detect subtle changes in tissue resistance during insertion, providing essential tactile feedback. The needle's hub is traditionally transparent, enabling immediate visualization of cerebrospinal fluid return, which confirms proper placement. Enhanced with depth markings along the shaft, these needles facilitate precise depth control during procedures. The design also includes a close-fitting stylet that prevents tissue coring during insertion, reducing the risk of complications. Modern Quincke tip spinal needles often feature ergonomic hubs for improved handling and control during delicate procedures.
