Ovarian Stroma Biopsy Needle by ZorayPT

ZorayPT’s ovarian stroma biopsy needle (Model ZPT-VELSABN-004) is the world’s only 60 cm spring-loaded instrument specifically engineered for transvaginal ultrasound-guided ovarian stromal tissue collection in large breeding animals — mares, cows, and other livestock. This pioneering device enables reproductive researchers and veterinarians to harvest high-integrity stromal samples under real-time ultrasound guidance via standard follicular aspiration platforms, dramatically advancing studies on follicular development, ovarian reserve, anti-Müllerian hormone (AMH) profiling, and fertility optimization programs.

To deliver reliable semi-automatic performance at an unprecedented 600 mm working length, ZorayPT completely re-engineered every component in-house:

• Cannula and stylet are precision-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 stromal samples even from dense ovarian 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-004 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.
