Egg Collection Needle and Instruments – Description

During transvaginal oocyte retrieval, a specialized aspiration needle is used to puncture ovarian follicles under ultrasound guidance. The needle is typically a 17G single-lumen or double-lumen stainless-steel needle with an echogenic tip for clear visibility on ultrasound. It is inserted through a needle guide attached to a transvaginal ultrasound probe.

The aspiration needle is connected via sterile suction tubing to a vacuum pump, which provides controlled negative pressure to gently aspirate follicular fluid into pre-warmed sterile test tubes. These tubes are placed in a test tube warmer to maintain a temperature of 37°C, crucial for oocyte viability.

The setup also includes sterile flushing medium (if needed), vaginal speculum, disinfectant for vaginal prep, and sterile surgical drapes. A trained embryologist retrieves the oocytes from the aspirated fluid in the IVF lab immediately post-procedure
