Egg Retrieval Needle
Egg Retrieval Needle
Egg Retrieval Needle:
1. High-quality Medical SUS304, high strength, to avoid bending.
2. The ultrasonic identification mark at the tip of the needle is processed by special technology, which has a better recognition effect and determines the position more accurately and reduces the operation time.
3. The smoothness of the inner and outer walls of the needle reaches mirror level.
4. The tip of the needle is designed with a double-edged inverted triangle, which is sharper and can quickly puncture the oocyte.

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).

FAQs
Q: What kind of needle is used for egg retrieval?
A: Traditionally, 19-gauge needles have typically been used for egg retrieval procedures in IVF treatments. However, smaller needles offer significant benefits as they reduce the risk of puncturing follicles.
