Biopsy Needle
Biopsy Needle
Fabricated from high-strength medical-grade stainless steel tubing and solid rods, these coaxial components (inner trocars with specimen notches and outer cutting cannulas) are designed for soft tissue and bone marrow biopsy systems. Precision-machined using Japanese high-speed grinding, laser notch cutting, and ultrasonic cleaning for uncompromised sample integrity.

Biopsy Needle: Precision Tissue Sampling for Definitive Diagnosis.
Biopsy Needle Clinical Purpose
Our biopsy needle delivers unparalleled accuracy in obtaining high-yield tissue cores for pathological analysis. Designed for ultrasound, CT, or MRI-guided procedures, it enables reliable sampling of lesions in organs including liver, breast, prostate, and lung—critical for cancer diagnosis, staging, and treatment planning.
Key Advantages
High-Precision Laser Notch Cutting
Smooth, burr-free specimen notch edges with tight depth and length controls ensure intact,high-volume core tissue yields.
Ultra-Sharp Outer Cutting Edge
Precision multi-bevel or reverse-bevel outer cannulas slice tissue cleanly with minimal resistance, preventing crush artifacts.
Precision Coaxial Clearance
Closely controlled inner/outer needle tolerances and straightness ensure smooth,zero-jam gliding during high-speed spring-fired cutting.
Ultraclean Washing & Degreasing
Multi-stage ultrasonic cleaning and WFI rinsing eliminate micro-grinding debris and oil residues, satisfying medical biocompatibility standards.
Quality Control (ISO 13485 QMS)
100% High-Speed Online Vision Inspection
Real-time screening and auto-sorting of bevel geometry, notch dimensions, coaxial alignment, and burrs.
Micro-Cleanliness & Particulate Monitoring
Regular lot testing for residual oils and particulate matter.
Full-Dimension & Cutting Force Verification
Tight control over dimensions, coaxial sliding friction, and batch cutting performance.
Applications
– Core needle biopsy (CNB) of tumors
– Breast biopsy under stereotactic guidance
– Transrectal prostate sampling
– Lung nodule FNA/FNB procedures

FAQs
Q: How painful is a needle biopsy?
A: A needle biopsy is generally not very painful, with most patients describing the sensation as pressure rather than pain. Local anesthesia is used to numb the area, making the procedure itself feel minimal after the initial injection. Post-procedure, you may experience mild soreness or tenderness that can be managed with over-the-counter pain medication.
Q: What is the prep for a needle biopsy?
A: If you are having a needle or surgical biopsy, ask your health care provider if you need to stop taking any medications before the procedure. Your doctor may tell you not to eat or drink for eight hours before your biopsy. However, you may take your routine medications with sips of water.
Q: What kind of biopsy requires sedation?
A: General anesthesia: It is most often used for the most invasive biopsies, such as those in which tissue is drawn from inside the chest or abdomen, and for biopsies in which the patient must remain relaxed or still.
Q: Does a needle biopsy leave a scar?
A: If you had a core needle biopsy, the cut the doctor made in your skin, called an incision, may leave a small scar. This usually fades with time. You can go back to most of your usual activities right away.
Q: How long until I get my biopsy results?
A: Your biopsy sample will be reviewed by a pathologist, and the results will be given to your doctor. Your doctor will then share the results with you. This usually takes about a week.
Q: What is a biopsy needle?
A: A biopsy needle is primarily used to obtain samples of living tissue, cells, or fluid from the human body for pathological examination. It is currently one of the “gold standard” clinical methods for diagnosing tumors, inflammation, and organ pathologies.
