BIOPSY NEEDLE

The Biopsy Needle is a professional-grade, high-precision surgical instrument engineered to extract tissue or fluid samples from a patient’s body for pathology examination and diagnostic analysis. Available in core needle biopsy (CNB) and fine needle aspiration (FNA) configurations, these needles are designed to navigate deep anatomical structures with minimal trauma. Forged from high-tensile stainless steel, they provide exceptional structural rigidity, sharp cutting mechanics, and enhanced visibility under diagnostic imaging for precise sample acquisition.

Key Specifications

• Type: Core Needle Biopsy (CNB) / Fine Needle Aspiration (FNA) Diagnostic Instruments.

• Material Composition: Surgical-Grade Stainless Steel with medical-grade polymer hubs.

• Gauge Range: Broad spectrum depending on application (typically 14G to 18G for core tissues; 20G to 25G for fluid/cell aspiration).

• Length Variations: Available from short 5 cm needles for superficial lesions up to 20 cm+ for deep abdominal or pelvic access.

• Imaging Compatibility: Often equipped with echogenic or radiopaque tips for high-contrast visibility under ultrasound, CT, or X-ray fluoroscopy.

Common Types & Configurations

• Core Biopsy Needles (Semi-Automatic / Automatic): Features a spring-loaded firing mechanism consisting of an inner stylet with a specimen notch and an outer cutting cannula. It shears off a intact cylinder (core) of tissue, preserving histological architecture.

• Fine Needle Aspiration (FNA): A thin, hollow needle designed to harvest fluid or loose clusters of cells from cysts or solid masses using manual or mechanical suction for cytological evaluation.

• Bone Marrow Biopsy Needles: A heavy-duty, reinforced needle (such as the Jamshidi style) engineered with an ergonomic handle to penetrate dense cortical bone and extract marrow cores or aspirates.

Features & Benefits

• Echogenic Tip Enhancement: The distal tip is micro-machined or sandblasted to scatter sound waves efficiently, allowing interventional radiologists to track the needle's precise trajectory in real-time under ultrasound guidance.

• Ultra-Sharp Bevel Cutting Mechanics: Features a razor-sharp, multi-beveled tip configuration that slices cleanly through tough or fibrous lesions, minimizing target deflection and decreasing surrounding tissue trauma.

• Integrated Depth Markings: Laser-etched centimeter gradations along the needle shaft provide immediate visual confirmation of depth penetration, maximizing procedural safety.

• Color-Coded Hub Architecture: Incorporates standard international color coding on the hubs and packaging for rapid, error-free identification of needle gauge sizes during fast-paced surgical setups.
