Abstract

本实用新型是一种用于鼓膜修补术和鼓膜通气 管置入手术的医疗器械。由针套1、针芯5、弹簧8、 指环3、指环6组成。其特征在于针套1上安装有一 个可移动的标志卡4,针套1的前端安装有一个固定 卡2。该实用新型可以在两种手术中使用,而且操作 简单,使用方便、安全,能减轻患者痛苦,尤其适用于 对儿童及不易合作的患者进行手术。

Description

本实用新型是一种医疗器械,尤其是用于鼓膜修补及鼓膜通气管置入手术的鼓膜通气管置入修补器。
在现有的技术中,对以上两种手术均无定型、适宜的专用手术器械。在手术中需采用多种器械,手术操作过程复杂、精度要求高,由于鼓膜的特殊生理解剖部位造成视野不清,使手术过程中难以掌握,尤其是患者不够合作的情况下,极易伤及鼓室内侧粘膜、镫骨,锈发迷路炎等不良后果。
本实用新型的发明目的就是要提供一种可以替代现手术操作中多种器械功能的、操作简单、方便、安全的鼓膜通气管置入修补器。
本实用新型的发明目的是这样实现的:鼓膜通气管置入修补器由针套和针芯两部分组成。针芯和针套上均安装有指环,其特征在于针套上安装有一个标志卡,针套前端安装有一个固定卡,在针芯上固定有一个针芯弹簧。如进行鼓膜通气管置入手术时,将针套上的标志卡移动至鼓膜距外耳道口的长度,将针芯插入针套内,按紧指环,在针芯露出针套的针尖上套上通气管,将针套向耳道内移动至标志卡的深度时,即示鼓膜穿通,放松指环,针芯在弹簧作用下退回针套,通气管既置在鼓膜上,手术完成。如进行鼓膜修补术时,将置入膜(大蒜瓣膜或鸡蛋内膜)贴在固定卡上,将针套置入耳道内至标志卡处,用针芯轻顶置入膜或向针套几吹气,就可使置入膜固定在鼓膜上,退出针套,则手术完成。
本实用新型与现在技术相比,使用方便、安全,便于医务人员的操作,尤其适用于对儿童及不易合作的患者进行手术。可减少患者的痛苦。
附图1是本实用新型的剖面示意图。
在图1中,用金属制成的针套1前端用螺纹方式安装有一个用塑料或金属制成的圆形固定卡2,针套1后部以螺纹或焊接方式固定有一个用金属制成的指环3,在针套1上安装有一个塑料或金属制成的标志卡4,标志卡4是套在针套1上,可前后移动。用金属制成的针芯5后端以螺纹或焊接方式固定有一个用金属制成的指环6,针芯5的针体7后端通过焊接方式固定有弹簧8,针体7的长度略长于针套1。
