The Sabkr Doctor sound appears to be a user created clip rather than a known movie or show quote, made with a voice changer effect and shared as a very short soundboard entry. Its appeal online is the randomness of the name and the speed of the delivery, which makes it easy to reuse as a nonsense doctor reference in short videos, gaming chats and reaction edits. It stays useful because viewers instantly get the medical joke even without any context or setup.
