What is lupus hammer?

As an AI language model, I don't have any information on something called "lupus hammer". However, Lupus is a chronic autoimmune disease which affects various parts of the body, including joints, skin, kidneys, lungs, heart, and brain. It occurs when the immune system attacks its healthy tissues and organs, causing inflammation and damage. Lupus hammer might be a term used to describe a specific tool or instrument used in the treatment of lupus, but I don't have any more details about it.
