Peekaboo Prober capsules are devices used for looking inside the body. Patients are not given a chance to swallow these capsules, they are launched into the throat. Aboard the capsule is an artificial intelligence that communicates with a doctor through radio. The prober can navigate as it pleases through the body, they can even exit the body and still fly across the room. The capsules may be trusted enough to diagnose patients, but they cannot tell the difference between a mummy and living humans head. Apparently, Dr. Radius does not need to retrieve them from patients bodies when they are through with the exam. The capsules are equipped with horns so that may creatively inform patients of their impending death.
