Description

鼻中隔双切刀
技术领域  本实用新型属于手术器械，是用于鼻中隔成形术的仪器。
背景技术  以往鼻中隔黏膜下切除术由于切除了大部分中隔软骨，术后易出现外鼻下榻、中隔穿孔及经鼻呼吸时中隔黏骨膜随呼吸飘动等。目前国内外均提倡以鼻内镜下鼻中隔成形术逐渐代替传统的鼻中隔黏膜下切除术，而把弯曲的中隔软骨行条状切除将其重新塑型是鼻中隔成形术的重要步骤，应用传统刀片行条状切除中隔软骨时易伤及对侧黏软骨膜形成穿孔，使手术操作难度较大，对术者的操作水平要求较高。
发明内容  本实用新型的目的是克服以上不足，提供一种操作方便、成本低廉且不易损伤对侧黏软骨膜形成穿孔的鼻中隔双切刀。
本实用新型的技术方案：本实用新型由刀把、刀柄和左右刀刃组成。左右刀刃之间相距1mm，每个刀刃的宽为1mm，长为5mm；刀柄长30mm，与刀把成20°角；刀把长60mm。
本实用新型克服了以往鼻中隔成形术中条状软骨切除的复杂性及危险性。其制作技术简单，成本低廉，术中易于操作。
附图说明  图1是本实用新型的侧视图。
          图2是本实用新型的俯视图。
具体实施方式
本实用新型由刀柄(2)、左右刀刃(1)和刀把(3)组成。左右刀刃(1)呈半圆弧形，每个刀刃的宽为1mm，长为5mm，左右刀刃之间相距1mm；刀柄长30mm，与刀把成20°角；刀把长60mm。使用时，将双刃刀片放置于所需条状切除的中隔软骨上，轻轻用力在软骨上作出相距1mm的两个平行切口，形成宽为1mm的软骨条，把软骨条一侧撬起，将其切除，可根据中隔弯曲程度切除数条软骨，将中隔重新塑型使其平直。

Claims (2)
