为减少喉显微激光手术所冒损伤前连合、声带及随之而形成的喉蹼之风险,作者在前连合喉镜的基础上,设计了一种新的简单的器械。其远端为一金属叶片,当一侧声带作激光手术时其可遮蔽另一侧,以期达到防护之目的。其远近端之间用一细长金属连接,近端固定一小夹具,可调节适合于各种喉镜的长度,并可顺中轴转动其角度,使之可精确地置于声带之间。细长金属近端弯曲以保持术者视野清楚。器械表面应无光泽,以防光线折射。据信 To reduce the risk of pre-injury commissures, vocal cords and the formation of throat webs in laryngeal laser surgery, the authors designed a new, simple instrument based on preneoplastic laryngoscopes. The distal end of a metal blade, when the vocal cords for laser surgery on the other side can be shielded, in order to achieve the purpose of protection. A slender metal connection is used between the far and near ends. A small clamp is attached to the proximal end to adjust the length of each laryngoscope. The angle can be adjusted along the central axis so that it can be accurately placed between vocal cords. Elongated metal proximal curved to keep the surgeon clear vision. The surface of the instrument should be dull, to prevent light refraction. It is believed that
