About the Allen Intestinal Clamp
The Allen intestinal clamp is a ring-handled clamp that one instrument maker lists under gastrointestinal forceps and clamps. Its long, straight jaws carry longitudinal serrations (parallel grooves that run along the jaw) and end in a 1×2 tooth arrangement.
Device registry descriptions of the pattern note that grooves or serrations on the blades provide grip.
Teleflex lists several jaw lengths, including a delicate paediatric size. Other makers offer similar ranges, so jaw length and overall length should be checked in the specific catalogue.
