It also known as Lorna-Edna Towel Clamp, Curved, Serrated, Non-Perforating are a non-perforating clamp used to secure instruments, and surgical materials such as tubing and towels to the drape surrounding a surgical site. The jaws and tips are curved while the shanks and handle are flat so they can rest on the patient. The teeth on the tips of this towel clamp are blunted so they grip tightly but do not penetrate the surgical drape. They also have ratcheted finger ring handles so a firm hold can be secured. The Lorna Towel Clamp is also commonly referred to as the Edna Towel Clamp. This clamp should never be used on skin. This product is 130 mm long.
