Description

钩突切除刀
技术领域
本实用新型涉及一种钩突切除刀。
背景技术
在功能性鼻窦内窥镜手术中，现有的用于切除钩突的镰状刀，其刀柄与连接于刀柄前侧的刀刃位于同一平面上，在进行手术操作时，由于鼻腔空间狭小，故难以操作，效率低；手术后往往因钩突切除不完整致使上额窦口未能充分开放，影响手术效果。
发明内容
本实用新型的目的是要提供一种钩突切除刀，该刀具特别适合在人体鼻腔的狭小空间内进行手术操作，以利医师准确快速地切除钩突，以充分开放上颌窦口，提高疗效。
本实用新型的钩突切除刀包括刀柄和联接于刀柄前侧的扁平状刀部，其特征在于：所述扁平状刀部与刀柄连接处形成钝角，所述刀部外缘设有刀刃。
当医师手持刀柄将刀部置入人体鼻腔并使手柄作纵向摆动时，由于刀部拐向旁侧，故有利于医师进行有效的切割。从而能提高手术效率，和疗效。
附图说明
图1为本实用新型的实施例主视图。
图2为图1的k向视图。。
图3为图2的A-A剖示图。
具体实施方式
本实用新型钩突切除刀，包括刀柄和联接于刀柄前侧的扁平状刀部，其特征在于：所述扁平状刀部与刀柄连接处形成钝角，所述刀部外缘设有刀刃。
为了改善刀具的使用功能，所述的扁平状刀部的前端凸起，旁侧部开有弧形小缺口。所述钝角角度为91°～160°。
本实用新型，操控方便，切除钩突手术疗效好，具有较大的推广应用价值。
