Dual Tip Technology Advantages Of 16G-27G Stainless Steel Spinal Needle

Aug 02, 2026

 

The 16G-27G Medical Grade Stainless Steel Spinal Needle provides two mainstream professional tip designs: Quincke Point and Pencil Point, covering all mainstream clinical spinal puncture and anesthesia scenarios. The two tip structures adopt different mechanical principles and clinical adaptation logics, forming a complementary full-scenario solution. The dual-type tip design is a core technical highlight of this series of spinal needles, which greatly improves the clinical adaptability and surgical safety of the product.

The Quincke Point is a classic beveled sharp tip, professionally designed for high-efficiency penetration of dense tough tissues. The sharp bevel edge can quickly cut through fibrous tissues such as the supraspinous ligament, interspinous ligament, and ligamentum flavum, with strong breakthrough ability and short puncture time. In clinical application, Quincke Point spinal needles are mostly matched with 16G-19G large and medium gauges, suitable for adult patients with thickened lumbar ligaments, obese patients, and emergency lumbar puncture operations that require rapid positioning. The sharp tip effectively avoids needle slipping and insufficient penetration, ensuring one-time successful puncture in complex tissue environments and improving surgical efficiency.

In terms of technical craftsmanship, the Quincke Point of the 16G-27G series adopts precision CNC integrated grinding technology, with uniform bevel angle, smooth cutting edge, and no burrs. The standardized tip angle ensures consistent penetration resistance of each needle, enabling doctors to form stable operating habits and improve the repeatability of surgical operations. It is widely used in conventional spinal anesthesia for orthopedics, obstetrics and gynecology, and general surgery, and is the most commonly used tip type for routine clinical neuraxial operations.

The Pencil Point is an atraumatic rounded tip designed for minimally invasive and low-complication operations. Different from the cutting principle of the Quincke tip, the pencil-shaped round tip adopts a tissue separation mode, which gently pushes apart ligament fibers, soft tissues, and tiny blood vessels without cutting damage. This design can effectively reduce the incidence of postoperative cerebrospinal fluid leakage, puncture headache, and nerve stimulation reaction, and is the preferred tip type for high-precision minimally invasive puncture.

Pencil Point spinal needles are mainly matched with 20G-27G medium and fine gauges, focusing on high-safety groups such as pediatric patients, elderly patients, and critically ill vulnerable patients. The round and smooth tip makes the breakthrough sensation of the ligamentum flavum more obvious, helping doctors accurately control the needle entry depth and avoid excessive penetration that damages the spinal cord tissue. In outpatient minimally invasive examination, postoperative analgesia anesthesia, and pediatric spinal anesthesia scenarios, Pencil Point needles can significantly improve patient comfort and reduce postoperative recovery cycle.

The dual-tip optional design of the 16G-27G full-series spinal needle realizes full coverage of "high-efficiency puncture + minimally invasive safety" clinical needs. All tips are made of medical-grade stainless steel with integrated molding, featuring stable structure, high precision, and strong durability. This flexible collocation mode enables the product to adapt to differentiated surgical scenarios and patient groups, making it a highly flexible and professional neuraxial puncture device in the global medical device industry.
