Side-notch biopsy gun handpiece/needle

A side-notch biopsy gun handpiece is a manual, spring-loaded surgical tool used to extract small tissue samples for pathological testing. The device features a needle with a side notch that cuts a precise core of tissue when fired, minimizing damage to surrounding areas. Clinically, it is commonly employed in procedures targeting organs like the kidney, prostate, liver, and breast, often guided by imaging for accuracy.

These devices are typically single-use, non-electronic instruments regulated under surgical instrument classifications. They are designed for percutaneous use, meaning they are inserted through the skin to reach target tissues. Regulations may vary by jurisdiction, but they generally fall under strict medical device standards due to their invasive nature and direct patient contact.
