316L Stainless Steel Capillary Slotted Scale Puncture Biopsy Needle
The 304/316L Stainless Steel Capillary Tubing Slotted, Graduated Biopsy Puncture Needle is a sophisticated medical instrument engineered for precise tissue sampling and fluid aspiration. Constructed from medical-grade 304 or 316L stainless steel capillary tubing, it incorporates longitudinal slots near the tip for efficient tissue capture or fluid inflow, and clear laser-etched depth graduations for accurate insertion control. This design enhances the efficiency of biopsy procedures, minimizes sample fragmentation, and provides clinicians with real-time visual feedback on needle depth, improving procedural accuracy and patient safety.
| Parameter Category | Specification | Details & Options |
|---|---|---|
| Material | Tubing Material | 304 or 316L Stainless Steel (Medical Grade). 316L offers superior corrosion resistance for prolonged contact with bodily fluids. |
| Design Features | Slot Configuration | Single Slot or Multiple Slots near the tip. Slot length typically 10-20mm. Designed to facilitate tissue entry into the lumen or allow fluid inflow. |
| Graduation Markings | Laser-etched depth scale in centimeter (cm) and/or millimeter (mm) increments along the shaft. | |
| Tip Design | Chiba Style (Long Bevel): Common for FNA. Trocar Point: For easier penetration of tougher tissues. Franseen or Westcott: For improved core retention. |
|
| Dimensional Specifications | Outer Diameter (Gauge) | Fine Needle Aspiration (FNA): 20G (0.90mm), 21G (0.82mm), 22G (0.71mm), 25G (0.50mm). Core Biopsy: 14G (2.11mm), 16G (1.65mm), 18G (1.27mm). |
| Length | Common: 50 mm, 90 mm, 100 mm, 150 mm, 200 mm. Custom lengths available. | |
| Slot Dimensions | Length: 5-25 mm. Width: 0.3-1.0 mm (proportional to needle gauge). | |
| Performance | Flow/Aspiration Efficiency | Slotted design can improve sample yield by preventing tissue from plugging the tip and providing an alternative inflow path. |
| Depth Control Accuracy | Graduations allow for precise insertion depth monitoring, typically with an accuracy of ±1mm. | |
| Surface Finish | Internal & External | Electropolished to a smooth finish (Ra ≤ 0.4 µm) to minimize tissue drag and friction. |
| Hub & Connection | Hub Type | Clear or opaque hub with Standard Luer Lock (ISO 594) connection. May include a side port for syringe attachment. |
| Stylet (Optional) | Purpose | Obturates the needle during insertion to prevent tissue coring, then is removed for aspiration. |
| Sterility & Packaging | Sterilization | Ethylene Oxide (EtO) or Gamma Irradiation. |
| Packaging | Individual sterile blister pack, often with protective needle guard and/or introducer stylet. | |
| Quality & Standards | Biocompatibility | ISO 10993 compliant (Cytotoxicity, Sensitization, Irritation). |
| Sharpness Testing | Performed per ASTM F3014 or equivalent. | |
| Intended Use & Handling | Single-Use Device | Yes, to ensure sharpness and sterility. |
| Imaging Compatibility | Stainless steel is radiopaque, visible under X-ray/fluoroscopy. For ultrasound guidance, echogenic coatings or surface treatments are optional. |
