Corpus Luteum Biopsy Needle

Corpus Luteum Biopsy Needle by ZorayPT

ZorayPT’s corpus luteum biopsy needle (Model ZPT-VELSABN-003) is the definitive 60 cm spring-loaded instrument purpose-built for transvaginal ultrasound-guided corpus luteum tissue collection in large breeding animals — mares, cows, and other livestock. This groundbreaking device enables reproductive veterinarians and researchers to obtain large, intact, high-integrity luteal samples under real-time ultrasound guidance via standard follicular aspiration platforms, dramatically advancing studies on ovulation timing, luteal function, and progesterone profiling critical to embryo transfer and fertility management.

To deliver reliable semi-automatic performance at an unprecedented 600 mm working length, ZorayPT completely re-engineered the entire system 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 over 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 generous, undamaged luteal tissue samples even from dense corpora lutea.

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-003 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.
