Follicular Puncture Needle
Follicular Puncture Needle
Available as single-lumen needles or dual-lumen flushing sets, these cannulas are fabricated from ultra-smooth,thin-wall medical stainless steel tubing for transvaginal ovum retrieval in ART procedures. They are precision-machined on automated Japanese equipment to protect oocyte-cumulus complex integrity.

Follicular Puncture Needle: Precision Engineered for Atraumatic Oocyte Retrieval
Follicular Puncture Needle Clinical Purpose
Our follicular puncture 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.
Key Advantages
Ultra-Sharp Multi-Bevel Tip
Precise micro-bevel geometry minimizes penetration
resistance across the vaginal wall and ovarian capsule, reducing bleeding and trauma.
Mirror-Finish Inner Lumen
Ultra-low internal surface roughness minimizes fluid shear stress under aspiration vacuum, preventing mechanical damage to oocytes and cumulus-oocyte complexes.
High-Visibility Echogenic Tip
Distal micro-etched or sandblasted bands provide distinct,
blind-spot-free visualization under transvaginal ultrasound.
Ultraclean Washing &Endotoxin Control
Multi-stage ultrasonic cleaning and WFI rinsing ensure endotoxin and particulate levels satisfy stringent reproductive medicine standards.
Thin-Wall High-Flow Geometry
Maximizes internal aspiration throughput without compromising needle column puncture rigidity.
Critical Applications
Transvaginal ultrasound-guided oocyte retrieval
Natural cycle IVF procedures
Ovarian follicle aspiration
Embryo transfer fluid management
Quality Control(ISO 13485 QMS)
100%High-Speed Online Vision Inspection
Real-time verification and auto-rejection for bevel geometry, length, burrs, and echogenic band dimensions.
Micro-Cleanliness, Particulate & Endotoxin Audits
Lot testing for surface oils, micro-debris, and bacterial endotoxin levels.
Full-Dimension & Penetration Testing
Tight control over OD/ID tolerances, wall uniformity, and batch penetration performance.

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