Scissors, Surgical, Larynx, Endoscopic
Definition : Larynx surgery scissors designed to cut tissues during laryngoscopic procedures. These scissors are typically handheld, manual instruments with two small metallic (e.g., stainless steel) blades with straight or angled (to the right or left) sharp tips that slide past each other (i.e., shearing action). The blades are at the distal end of a long shaft that is attached, usually at a 60- to 90- degree angle, to handles with the proximal end conformed as a ring to facilitate holding and operating with the fingers. Sturdier laryngoscopic scissors with double-action lever mechanisms that permit more stable cutting of hard fibrous tissue with less rotation are also available. Larynx surgery scissors are used in many procedures, including the excision of large masses (e.g., the pedicle of polyps) and to cut the epithelium in surgical procedures intended to excise pathologic structures of the vocal cords (phonosurgery). They are used frequently in microsurgery.
