Veterinary biopsy needle

veterinarysemi-automaticsterile

Overview
ZorayPT’s extra-long semi-automatic veterinary biopsy needle is engineered for transvaginal ultrasound-guided ovarian stroma and corpus luteum sampling in large animals (mares and cows). The system provides a 600 mm working length while maintaining spring-loaded semi-automatic performance, enabling safe, real-time ultrasound-guided retrieval of intact luteal and stromal tissue for reproductive research, fertility assessment and embryo transfer programs.

Design & Construction

• Cannula and stylet: veterinary-grade 304/316L stainless steel with enhanced rigidity and inner-wall mirror polishing to minimize tissue drag over the extended length.
• Proprietary reinforced spring mechanism and optimized trigger engineered to deliver consistent throw and full firing power at 600 mm working length.
• Sample notch: standard 15 × 1.6 mm deep notch with cutting cannula (standard 16G; gauge customizable 14G–18G) for large, intact samples from dense luteal tissue.
• Lightweight ergonomic handle with dual safety locks and one-handed cocking; extended rigid shaft for column strength during deep transvaginal passage.
• Compatibility: luer-lock syringe compatible and designed to integrate with standard ultrasound follicle aspiration platforms.
• Sterilization & packaging: EO sterilized, blister-packed, 100% inspected under magnification to ensure surface finish and notch geometry integrity.
• Customization: gauge, notch depth, markings and other parameters configurable for research institutions and commercial breeders.

Key Features
