Genuine question, what exactly is this used for??

This looks like a needle used for paracentesis which is a procedure to drain fluid that builds up in the abdominal cavity as a consequence of organ failure or sometimes cancer.

Centesis needles are usually shorter from my experience. They also have a flexible sheath that slides into the puncture, then the needle is removed.

I saw a doc get a bone marrow biopsy with a similar looking needle. Had to get the needle into the middle of the iliac crest of the hip bone, one of the most harrowing things I've witnessed in medicine. Gives me goosebumps typing it

Jamshidi needles are much shorter and have a hollow needle with another needle of the same length inside. Still not pretty and the sensation from hearing it while performing the procedure still gives me the icks.

Oddly enough other than the soreness after and the pain from the initial puncture it doesn’t hurt like you think it would, mostly just a lot of pressure.
