Scissors designed to cut tissue and/or material during surgical procedures. These scissors are typically handheld, manual instruments with two metallic (e.g., stainless steel) blades with sharp edges 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. Some surgical scissors intended for delicate procedures (e.g., ophthalmic, neurosurgery, microsurgery) have flat handles with serrations to provide a safer grip and inserted flat springs, avoiding uneven tension and providing a more uniform and/or sensitive manipulation. Small fine scissors with sharp blades are used to cut and dissect soft tissue; heavy-duty scissors are used for cutting stronger tissue such as tendons and cartilage; dedicated surgical scissors with a variety of tips and blades are available for particular procedures (e.g., ophthalmic, abdominal, arteriotomy, obstetric).
