Egg Retrieval Needle: Precision Engineered for Atraumatic Oocyte Retrieval
Egg Retrieval Needle Clinical Purpose
Our egg retrieval needle (ovum pick up needle) enables ultra-precise follicular puncture during transvaginal ultrasound-guided IVF procedures. Designed for maximal oocyte viability and minimal tissue trauma, it ensures efficient retrieval of intact cumulus-oocyte complexes (COCs) critical for successful assisted reproduction.
Ovum Pick Up Needle Key Advantages
Enhanced Ultrasonic Guidance
Laser-etched echogenic tip with proprietary micro-groove pattern delivers 50% brighter ultrasound signature vs. standard markers.
Precise real-time tracking reduces needle repositioning by ≥40%.
Optimized Penetration & Flow
Double-bevel inverted triangle tip (14° cutting edges) penetrates vaginal wall/follicles with 30% less force.
Mirror-polished lumen (Ra ≤0.08μm) prevents cell adhesion and maintains laminar suction flow.
Procedural Safety
High-strength SUS304 medical steel resists bending during angled access.
Smooth OD transition eliminates tissue snagging (VAS pain score ≤1.8/10).
