Semi-automatic Ovarian Biopsy Needle by ZorayPT

ZorayPT’s semi-automatic ovarian biopsy needle (Model ZPT-VELSABN-002) is the world’s first and only 60 cm spring-loaded veterinary biopsy system specifically engineered for transvaginal ultrasound-guided ovarian tissue sampling in large breeding animals — mares, cows, and other livestock. This breakthrough device allows reproductive specialists to safely harvest high-integrity samples from ovarian stroma and corpus luteum under real-time ultrasound guidance via standard follicular aspiration platforms, dramatically advancing fertility research, embryo transfer programs, and hormonal studies.

To achieve a full 600 mm working length while retaining the speed and reliability of semi-automatic operation, ZorayPT completely re-engineered every critical component in-house:

• Cannula and stylet are drawn from medical-grade 304 or 316 stainless steel with enhanced rigidity, toughness, and mirror-polished inner walls to eliminate tissue drag across extreme distance.
• Proprietary long-stroke reinforced spring mechanism and optimized trigger system deliver consistent, powerful firing at 60 cm with zero performance loss.
• 15 × 1.6 mm deep sample notch (customizable) surrounded by a 16G cutting cannula (14G–18G available) guarantees large, intact luteal samples even from dense tissue.

The lightweight ergonomic handle features dual safety locks and one-handed cocking, while the extended rigid shaft maintains perfect linearity during deep transvaginal passage. Fully compatible with all major ultrasound follicle aspiration guides and microconvex transducers.

Each ZPT-VELSABN-002 is EO gas sterilized, individually blister-packed, and 100 % inspected under magnification for flawless notch geometry and surface finish. Full customization of gauge, notch depth, handle color, and laser marking is available for research institutes and commercial breeders.
