Sklar's Cooley-Derra Atraumatic Forceps are a ratcheted, finger ring instrument commonly used for anastomosis in cardiovascular procedures. It is a partially occluding clamp that is frequently used to control blood flow from the carotid artery, aorta, and inferior vena cava. The atraumatic teeth provide a secure but delicate grip on vessels, causing little to no damage to the vessel walls. This instrument is offered in three sizes. This product has slightly curved shanks with a curvature that continues past the lock box into the jaws. The jaws follow the slight curvature of the shanks and towards the end angle to the left once, and then angle to the left again, creating a basket shape. There are 2x2 rows of fine, atraumatic teeth the entire length of the jaws and the tips are blunt and rounded. It is considered the small of the three available sizes. It's length is 6-1/2 inches.
