Abstract

本实用新型公开了一种麻醉注射针头,该注射针头包括中空针头1和后端的注射器接口2,该针头1前端为盲端,盲端为光滑的圆头,盲端侧壁分布多个出液孔3。使用此种结构的注射针头血管、神经损伤小、麻醉操作时间短。

Description

麻醉注射针头
技术领域
本实用新型涉及一种手术麻醉中使用的医疗器械,具体的说,是一种麻醉注射针头。
背景技术
目前,整形外科进行面部除皱、脂肪抽吸等手术时,通常采用局部浸润的麻醉方式,使用注射针头在软组织内反复穿刺,使麻醉液体均匀的注射到手术区域,存在的问题是:现有注射针头前端尖锐,反复穿刺对血管、神经造成损伤;针头仅有一个孔,注射速度慢,麻醉操作时间长。
发明内容
本实用新型的目的在于提供一种克服上述缺点、对血管、神经损伤小、操作时间短的麻醉注射针头。
本实用新型是这样实现的:一种麻醉注射针头,包括中空针头和后端的注射器接口,该针头前端为盲端,盲端为光滑的圆头,盲端侧壁分布多个出液孔。
本实用新型的优点是:针头为光滑的圆头,穿刺时,能大幅度减少对血管和神经的损伤;采用多个出液孔结构,可将液体快速注射到组织的上下、左右,达到均匀的效果,麻醉操作时间短。
附图说明
以下结合附图对本实用新型的具体实施方式做进一步说明。
附图为本实用新型示意图。
具体实施方式
如图所示,本实用新型包括中空针头1和后端的注射器接口2,针头1前端为盲端,盲端为光滑的圆头,盲端侧壁分布多个出液孔3。
使用时,先使用相同口径的穿刺工具将皮肤戳孔,然后,从孔内插入本注射针头,在皮下进行扇形的反复穿刺,将麻醉液体均匀的注射到手术区域。
