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

Optimal Sample Integrity

– Twin-bevel cutting edge: Ultra-sharp 14° tip preserves tissue architecture with minimal crushing artifact.
– Adjustable throw length (10–25mm): Customizable penetration depth for precise lesion targeting.

Enhanced Safety & Control

– Echogenic distal notch: Real-time ultrasound visibility with 360° rotational alignment.
– One-handed firing mechanism: Smooth trigger operation reduces hand tremor risks.

Procedural Efficiency

– Core sample retrieval >98% success rate (per Radiology 2024 study data).
– Integrated vacuum assist maintains sample cohesion during withdrawal.

Advanced Material Engineering

– Cannula: Electropolished 304VM stainless steel (wall thickness: 0.13mm) for superior flexural strength.
– Trocar: Tungsten-carbide reinforced tip (HRC 62±2) retains sharpness through dense tissue.
– Coating: Hydrophilic polymer (contact angle: 12°) reduces insertion force by 50%.

Applications

– Core needle biopsy (CNB) of tumors
– Breast biopsy under stereotactic guidance
– Transrectal prostate sampling
– Lung nodule FNA/FNB procedures

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.
