Vascular surgery scissors designed for excision of the atheromatous tunica intima of the carotid arteries (i.e., endarterectomy). These scissors are typically handheld, manual instruments with two metallic (e.g., stainless steel) slender, angled, or straight blades with very sharp tips that slide past each other (i.e., shearing action). The blades are usually attached to handles with the proximal end conformed as a ring to facilitate holding and operating with the fingers; both parts are joined by a swivel pin in the center. Endarterectomy scissors are mainly used in vascular procedures intended to treat stenosis of the common carotid artery; they may be also used for endarterectomy of other main arteries.
