Complete Specification System And Color Code Identification Standard Of Medical Stainless Steel Spinal Needle

Medical Stainless Steel Spinal Needle has formed a complete and standardized specification system covering 12 mainstream gauges from 16G to 27G, with a standard working length of 90mm and flexible customized length services. Equipped with a unified international color code matching system, each needle size corresponds to an exclusive identification color, which realizes rapid identification and accurate selection in high-intensity clinical operations, and is an important guarantee for standardizing lumbar puncture operations and reducing medical errors in the medical device industry.

The size gradient of the spinal needle strictly follows the international medical needle gauge standard, and the outer diameter of the needle tube decreases sequentially from 16G to 27G, forming a scientific and differentiated product layout suitable for different patient groups and clinical scenarios. The large-size specifications represented by 16G (White) and 17G (Light Purple) have thick needle tubes and strong puncture penetration. They are suitable for adult patients with thick subcutaneous tissue and high spinal cavity pressure, and are mostly used for emergency cerebrospinal fluid drainage and high-dose spinal anesthesia injection scenarios that require efficient fluid circulation and rapid operation progress.

Medium-size specifications including 18G (Pink), 19G (Light Grey) and 20G (Yellow) are the most versatile conventional models in clinical practice. They balance puncture efficiency and minimally invasive effect, with moderate needle tube thickness, which can ensure smooth completion of routine lumbar puncture sampling and spinal anesthesia while controlling tissue damage. These specifications are widely used in general surgery, orthopedics and neurology conventional diagnosis and treatment projects, and are the mainstream stocking products of most primary and secondary hospitals.

Small and ultra-fine size specifications from 21G to 27G are oriented to delicate and high-precision clinical scenarios. 21G (Green), 22G (Black) and 23G (Dark Blue) fine needles are suitable for elderly patients, obese patients and patients with fragile spinal tissue, effectively reducing postoperative bleeding and pain. Ultra-fine specifications such as 25G (Orange), 26G (Brown) and 27G (Grey) are specially used for pediatric spinal anesthesia and infant lumbar puncture diagnosis. The ultra-thin needle body avoids damage to immature spinal nerve tissue and greatly reduces the risk of cauda equina nerve irritation and compression injury.

The 90mm standard length meets the puncture depth requirements of most adult and adolescent patients. For special groups such as tall patients, severely obese patients and patients with spinal deformities, manufacturers can provide personalized customized length services according to 2D/3D drawings or physical samples provided by customers. The unified color code system completely solves the problem of difficult identification of similar specifications, enabling medical staff to quickly select matching needle types according to patient conditions and operation needs, effectively improving clinical operation efficiency and safety, and promoting the standardized development of the spinal needle industry.
