Product Application:

This is a specialized medical/surgical puncture needle designed for procedures requiring precise depth control and secure handling, often in contexts where a standard hypodermic needle is insufficient.

• Orthopedic Procedures: Bone marrow aspiration/biopsy, joint aspiration (arthrocentesis), or injections into bony or dense tissue sites.

• Interventional Radiology: Guiding needle for drain placements or as an initial access needle for Seldinger technique in vascular or fluid collection procedures.

• Veterinary Medicine: Large animal joint taps or fluid sampling where a robust, clearly marked needle is required.

• Specialized Laboratory Sampling: Percutaneous fluid collection from research animals or for sampling from sealed containers where depth penetration is critical.

Product Description:

This product is a sterile, single-use puncture needle crafted from 304 stainless steel, featuring several key user-focused enhancements. It has a standard beveled point (common angles: 12°, 15°, or 20°) for efficient tissue penetration. The needle shaft undergoes uniform sandblasting, which provides a matte, non-reflective finish. This improves grip for the clinician and reduces glare under procedure lights. Most distinctively, the needle features permanent, laser-engraved depth graduations (刻度) along its length, typically at 1cm or 5mm intervals. These high-contrast markings allow for real-time visual confirmation of insertion depth, enhancing procedural accuracy and safety. It is a fundamental, reliable tool optimized for controlled percutaneous access.
