The process for removing actual bone marrow is a little more delicate than just shoving the corkscrew needle into the bone. Its akin to getting a spinal, just on a different part of the body, and is usually done in the operating room.

They might use something else in these type of cases but when they just need bone marrow for testing I know how its done and they use that tool. They drive in down into the bone (by hand), the suck out the core of bone they cut out using that tool. I saw it done and know this for a fact.
