The Graham Field-2698 is a heavy-duty surgical instrument marketed under the Grafco brand. Kocher forceps are distinct from standard hemostats because they feature 1x2 interlocking teeth at the very tip of the jaws. This "rat-tooth" design, combined with full-length transverse serrations, allows the instrument to exert a powerful, non-slip grip on tough structures such as bone, fascia, or heavy ligaments. While they provide superior holding power, they are considered traumatic and are typically used on tissue that will be removed or where a crushing grip is acceptable for stability.
