Instrument Introduction

The spindle, just like the heart of the ovum, is composed of microtubules. The chromosomes are arranged in the center of the spindle, but most of the spindle is below the polar body. During ICSI, the embryologist will place the polar body of the egg at its 6 or 12 o'clock position to prevent the needle from sticking to the spindle.

According to the study, about 15-30% of the spindles are not located below the polar body, especially in patients with advanced ovum or premature ovarian failure. The spindle deviation angle tends to be relatively high, so the ovum may still be stabbed during the ICSI process.

With the Olympus spindle view, directly seeing the location of the spindle, which may be away from the polar body, reduces the chances of damaging the spindle apparatus. Knowing if oocytes are at metaphase II and if it’s in optimal condition, is essential for successful fertilization.

This system has excellent resolution and working distances, and an optional DIC prism for IMSI.
