We primarily use this Stryker laparoscope with our sheep artificial insemination program. While it’s very difficult to artificially inseminate sheep because of the anatomy of their cervix, this laparoscope makes surgical insemination possible.
What’s good about it
To artificially inseminate sheep, we go into the abdomen, locate the uterus, isolate it, and inseminate into the lumen of the uterus through the uterine wall. This procedure uses two keyhole incisions—one for the working tools and one for the laparoscope. We inflate the abdomen so there’s space to visualise what we are doing.
The shape of this laparoscope is perfect for the procedure. It’s a good diameter and the 30-degree angle makes it easy to work with the size of the sheep and our equipment set-up. It effectively allows you to visualise and isolate structures without holding your arms in an awkward position.
There’s an attached LED light source and we attach a camera so the image is shown on a computer screen. Not only can the client see what we are doing but the vet can work at arm’s length to the animal.
This procedure typically takes place in a farm setting—in shearing sheds with sheep in pens and cradles for restraint. This laparoscope is durable and sturdy. If it gets a bit of a knock from my boot or a chair or an animal, it’s not going to easily break. It’s plugged directly into a power point so there’s no need to worry about batteries.
I would also like to mention that Austvet Endoscopy are very good at refurbishing equipment. They refurbished a unit for us at a reasonable cost so we have a back-up in case anything goes wrong while we’re on the farm.
What’s not so good
The end can sometimes get a bit foggy and hard to see through. When you’re working in a body cavity that’s not full of fluid, that happens with most laparoscopes.
