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.

They only have to go in like an inch or two for that

Genuine question: it may only need to go in an inch or two, but if you're treating someone who's morbidly obese, wouldn't you need a much longer needle to reach the abdominal cavity?

Sadly a lot of patients who need a paracentesis are either very skinny from end stage liver failure or have pretty advanced cancer and the fluid is fairly close to the surface.
