Scissors, Surgical, Vascular, Artery, Coronary, Circumflex
Definition : Vascular surgery scissors designed for fine and sharp incisions of the circumflex artery (i.e., a branch of the left coronary artery that curves back of the left ventricle in the coronary sulcus, supplying the left ventricle and the atrium). These scissors are typically handheld manual instruments with two metallic (e.g., stainless steel) small, straight blades with very sharp tips that slide past each other (i.e., shearing action); the blades are usually mounted at a 90-degree angle to very long shanks and are joined by a swivel pin in the center, located at the point of union with the shank. The shanks are finished at the proximal end in handles conformed as a ring to facilitate holding and operation with the fingers; a stabilizing bar is frequently located on the shanks between the union of the blades and the ring handles. Circumflex artery surgery scissors are used in cardiovascular procedures involving the coronary arteries, including coronary anastomosis
