If someone uses probe holder for ovum pick-up procedure in cows(mares) or has access to a "real" one, it would be very helpful to take measurements of this holder for me.
I find it easier to take the probe in by hand. Using a probe holder (what we call an introducer) takes longer to find the ovaries. For examining the uterus (for pregnancy) we use BCF scanners which come with a proprietary plastic introducer. Before that we had a stainless steel one that we had made up by a local engineering shop, just a piece of 20 x 5mm steel about 700mm long with a probe holder at one end and a round handle at the other. The size of the bit that holds the probe depends on the size of the probe! We taped the probe on with insulation tape. Note that you can only have one layer of tape over the emitting side of the probe or you won't see much...
Thank You for trying to help me, but the ultrasound probe holder I'm asking about is used for needle collection of unmatured oocytes from the ovaries under ultrasound control for further in-vitro maturation and fertilization.
When using an ultrasound device, depending on the type of animal, when examining the ovary, the device should be placed near the location of the ovary or the member to be examined increases the experience through repetition. Fluid density and tissue affect measurements
I'm asking about ultrasound probe holder (not extender) for oocyte collection (not ovarian examination). It's introduced in to vagina (not rectum) close to the cervix, and holding the ovary by hand (rectally) against the ultrasound micro-convex probe oocytes are collected. It should be something like on the picture attached.
