A sterile, high-precision selection of disposable biopsy needles designed for harvesting high-quality histopathological core samples from soft tissue organs (such as the liver, kidney, breast, and prostate). This collection features semi-automatic and fully automatic spring-loaded biopsy guns and coaxial needles engineered with razor-sharp beveled tips to maximize sample volume while minimizing patient trauma. Each needle includes integrated centimeter depth markings for accurate placement under ultrasound or CT guidance and an ergonomic handling design for precise, one-handed medical manipulation.
