Payr-Baby Pylorus Clamp is a popular instrument typically used to treat pyloric stenosis, which is a term used to describe the narrow opening of the stomach that goes into the small intestine in a small child. During a Pyloromyotomy, for instance, the 2 3/16″ jaw length can be used to temporarily close the end of bowel. This instrument also contains longitudinal serrations on the jaws that help assure a tight grip, as well as receiving the option of having the jaw tip with or without a pin.
