Abstract
Disclosed is an aneurysm clip pliers for applying an aneurysm clip to a blood vessel. The pliers have a hand grip end and a barrel end. A pusher bar reciprocates within the hollow barrel portion causing the Y-shaped clip grip to open or close, depending upon the position of the push rod. A trigger mechanism causes the spring loaded pusher bar to shift toward the Y-shaped grip when the trigger is squeezed. A locking mechanism enables an aneurysm clip to be placed between the arms of the Y-shaped grip and retained therein until the aneurysm clip is to be applied on the blood vessel. The barrel end is rotatable through 360° with respect to the hand grip end of the aneurysm clip pliers, and the Y-shaped grip permits the aneurysm clip to pivot about an arc slightly larger than 180°. Accordingly, positioning the aneurysm clip on the defective blood vessel is easily accomplished.
