Biopsy Gun
The Biopsy Gun is a specialized medical device designed for accurate and efficient tissue sampling in diagnostic and interventional procedures. Widely used in oncology, radiology, nephrology, and pulmonology, it enables clinicians to obtain high-quality core tissue samples from deep or difficult-to-reach areas with minimal patient discomfort.
This device features a spring-loaded, quick-action mechanism that allows for precise insertion and retrieval of tissue. The trigger-based system ensures clean, controlled sampling, providing larger and more intact specimens compared to traditional fine-needle aspiration (FNA). This results in improved diagnostic accuracy, particularly in the identification of cancer, infections, and autoimmune diseases.
A biopsy gun is a fully automated spring-loaded biopsy instrument used in the medical field to obtain tissue samples from target lesions or organs. It fires a central stylet and cutting sheath in a rapid forward motion to collect a tissue core at a preset distance ahead of the needle tip.
Reliable, efficient, and easy to operate, the Biopsy Gun is an essential tool in core needle biopsy procedures, offering clinicians superior control and patient safety with every use.
Frequently Asked Questions
A Biopsy Gun is a spring-loaded, automated or semi-automated medical device designed to quickly and precisely obtain core tissue samples from internal organs or suspicious lesions for diagnostic examination, especially in cancer screening and histopathology.
There are two main types:
Automatic (Fully spring-loaded) – Fires both stylet and cannula in sequence
Semi-Automatic (Manually loaded stylet) – Offers more control, especially under ultrasound
Some models also include coaxial compatibility for multiple sampling with one puncture.
Biopsy guns are widely used in:
Breast, liver, kidney, prostate, lung, and thyroid biopsies
Soft tissue and lymph node sampling
Tumor grading and cancer diagnosis
Common sizes:
14G, 16G, 18G, and 20G
Lengths: 10 cm to 25 cm (or more, depending on the organ/site)
Most guns offer sample notch lengths of 10 mm or 20 mm
Most biopsy guns are single-use and disposable
Some systems have reusable handles with disposable biopsy needles
Always follow hospital protocol and manufacturer guidelines for reuse.
