What is the Oort cloud cosmos?

Excuse me, could you please clarify what exactly is meant by the "Oort cloud cosmos"? Is it a specific region or structure within our universe that's related to the Oort Cloud, a theoretical cloud of icy objects surrounding our Solar System? Or is it a broader term referring to some aspect of cosmology that I'm not familiar with? I'm curious to learn more about this concept and how it fits into our understanding of the universe.
