SUS304 ISO9626 , 20G Stainless Steel Biopsy Needle Tube For Tissue Samples Extraction , 0.9*0.15MM
A stainless steel biopsy needle tube is a cylindrical component of a biopsy needle, typically serving as the cannula (outer sheath) used to extract tissue samples. It is designed for precision, durability, and minimal patient discomfort during procedures like core biopsies or fine needle aspirations. The needle tube's construction from high-quality stainless steel ensures durability, corrosion resistance, and compatibility with sterilization methods. Smooth interior walls of medical biopsy needle tubes ensure intact tissue samples. Our company specilizes in producing semi-finished medical biopsy needle tubes with high quality and strict size tolerance. All biopsy needles are accorded with ISO9626 standard and meet the inspection requirements of ISO18457 standard. If the client require the capillary tubes for making biopsy needles, we can also provide the medical grade stainless steel 304, 316 capillary tubes.
Key Features Of Biopsy Needles:
- Stainless Steel Grades: Commonly medical-grade 304 or 316 stainless steel, chosen for high corrosion resistance, strength, and biocompatibility.
- Design: Hollow-core needles for extracting tissue samples (e.g., liver, breast).
- Sharpness: Precision-ground tip for clean penetration.
- Sterilization Compatibility: Autoclave, gamma radiation, or ethylene oxide.
- Electropolishing: Often applied to enhance surface smoothness and reduce microbial adhesion. Often electropolished to reduce friction and tissue trauma; some may have coatings for enhanced performance.
Design Considerations:
1. Gauge (Diameter): Ranges from 14G to 20G (lower gauge = larger diameter). Common sizes include 14G (2.1 mm), 16G (1.6 mm), 18G (1.2 mm), and 20G (0.9 mm).
2. Length: Typically 5 cm to 20 cm, with common lengths being 10 cm (superficial tissues) and 15–20 cm (deep-seated organs).
3. Sharpness: Precision-ground tips ensure clean tissue penetration.
4. Tip Design:
- Trocar tip: Sharp, bevelled edge for clean tissue penetration.
- Coaxial designs: Allow repeated sampling without reinsertion.
- Echogenic coatings: Enhance visibility under ultrasound guidance.
5. Imaging Compatibility: Designed to minimize artifacts in imaging techniques (e.g., ultrasound, CT).
Applications:
- Core Needle Biopsy: Larger-diameter tubes for obtaining tissue cores.
- Fine Needle Aspiration (FNA): Thinner tubes for fluid or cell collection.
- Specialized Procedures: Compatible with imaging-guided biopsies (e.g., breast, liver). Used with ultrasound, CT, or MRI for precision.
- Organ biopsies: Liver, kidney, prostate, breast, thyroid, and lung.
- Bone marrow aspiration: Larger gauges (e.g., 11–13G) for marrow samples.
- Veterinary Medicine: Tissue sampling in animals.
- Research: Histological studies and preclinical trials.
