Extra-long Semi-automatic Biopsy Needle (60cm Length) by ZorayPT

ZorayPT’s extra-long semi-automatic biopsy needle (Model ZPT-VELSABN-001) is the world’s first 60 cm veterinary semi-automatic biopsy system engineered exclusively for transvaginal ultrasound-guided ovarian stroma and corpus luteum sampling in large livestock — primarily mares and cows. This revolutionary instrument enables veterinarians to safely obtain high-quality luteal and stromal tissue samples under real-time ultrasound guidance via a follicular aspiration guide attached to a microconvex transducer, dramatically advancing reproductive research, fertility assessment, and embryo transfer programs.

Standard human semi-automatic biopsy needles max out at 25 cm — far too short for equine or bovine transvaginal access. To achieve a full 60 cm working length while retaining the speed and reliability of spring-loaded automation, ZorayPT completely re-engineered every component:

• Cannula and stylet are manufactured from ultra-high-grade 304/316L veterinary stainless steel with enhanced rigidity, toughness, and inner-wall mirror polishing to prevent tissue drag over extreme length.
• Proprietary reinforced spring mechanism and optimized trigger system deliver consistent throw at 60 cm without loss of firing power.
• 15 × 1.6 mm deep sample notch surrounded by a 16G (standard) cutting cannula (14G–18G customizable) guarantees large, intact samples even from dense luteal tissue.

The lightweight ergonomic handle incorporates dual safety locks and one-handed cocking, while the extended rigid shaft maintains perfect column strength during deep transvaginal passage. The needle is fully compatible with standard luer-lock syringes and existing ultrasound follicle aspiration platforms.

Each ZPT-VELSABN-001 is individually EO sterilized, blister-packed, and 100 % inspected under magnification to ensure flawless surface finish and notch geometry. Full customization of gauge, notch depth, and marking is available for research institutions and commercial breeders.
