Quincke Style Spinal Needle provides two mainstream needle tip types, Quincke Point and Pencil Point, and the scientific selection of needle tip structure is crucial to improving clinical puncture efficiency and reducing postoperative complications. The two structural designs have distinct functional characteristics and applicable scenarios, forming a differentiated clinical application system, which enables medical staff to select targeted needle types according to patient age, physical condition and surgical needs, realizing refined and personalized anesthesia puncture treatment.

The classic Quincke Point is the most widely used needle tip structure in conventional clinical operations. It adopts a precise beveled cutting design with sharp cutting performance, which can quickly penetrate human skin, subcutaneous fat, lumbar ligaments and dural tissue. The puncture process is smooth and efficient, with a high one-time success rate, which can effectively avoid repeated puncture and secondary tissue damage. This structure is very suitable for routine adult lumbar local anesthesia, conventional cerebrospinal fluid sampling and general lumbar puncture examination. Its stable and efficient performance can meet the high-efficiency operation needs of daily clinical diagnosis and treatment, and is the preferred model for most basic medical institutions.

The upgraded Pencil Point is optimized for high-precision and low-trauma minimally invasive surgical scenarios. Different from the cutting type of Quincke Point, the Pencil Point adopts a rounded blunt pencil-shaped structure, which will not cut dural fibers during puncture, but gently separate tissue fibers to complete puncture. This design can greatly reduce the risk of dural laceration and postoperative cerebrospinal fluid leakage, effectively reduce the incidence of postoperative lumbar puncture headache, and has significant advantages in reducing surgical trauma and complications. It is more suitable for long-duration anesthesia surgery, high-standard minimally invasive treatment and sensitive patient groups.

In clinical selection, doctors can make flexible matching according to actual surgical needs. For conventional short-time lumbar puncture and adult routine anesthesia, Quincke Point with high cost performance and high efficiency is preferred; for pediatric patients, elderly patients and long-time complex surgery, Pencil Point with lower trauma and higher safety is more suitable. The dual-type needle tip configuration of Quincke Style Spinal Needle covers all clinical scenario needs, realizing the perfect combination of conventional efficiency and high-end minimally invasive safety, and greatly improving the overall clinical application value of the product.
