Abstract

本实用新型股动脉介入穿刺针涉及了一种医疗器具,属于医疗器械技术领域。克服了传统穿刺针定位不准确,常需反复穿刺,易导致局部血肿、股动脉夹层等并发症及穿刺喷血后不能及时将指引导丝插入,造成失血过多,操作台面污染的缺陷。它包括穿设有侧孔5的穿刺针头1和设有侧通管3的穿刺手柄2组成,具有股动脉穿刺定位准确,操作步骤简单,有效地避免穿刺血肿、动脉夹层等并发症及指引导丝提前插入穿刺手柄内,缩短操作时间,减少了病人的失血量,减轻了操作台面污染的优点。

Description

股动脉介入穿刺针
技术领域
本实用新型涉及一种股动脉介入穿刺针,属于医疗器械技术领域。 
背景技术
血管内介入治疗的入路多采用股动脉穿刺,传统的穿刺针采用针头尖端开口,穿刺时定位不准确,常需反复穿刺,造成股动脉损伤,引起穿刺部位血肿、股动脉夹层等并发症,穿刺喷血后不能及时将指引导丝插入,造成失血过多,操作台面污染。 
发明内容
本实用新型的设计目的是为临床介入医师提供一种穿刺股动脉的专用穿刺针,以克服传统穿刺针操作繁琐,穿刺定位不准确,反复穿刺造成穿刺部位血肿、股动脉夹层等并发症,以及穿刺时导丝不能及时插入,造成失血过多,操作台面污染等缺陷。 
本实用新型包括穿刺针头1和穿刺手柄2,穿刺手柄2上设有侧通管3,侧通管3的管腔与穿刺手柄2的管腔相通,穿刺针头1的管腔与穿刺手柄2的管腔相通,穿刺针头1的前端为圆锥形的实体针尖4,针尖4的后方开有侧孔5,侧孔5设在侧通管3的同侧,近侧孔5处针尖4的斜面6为45度面。股动脉穿刺时,先将指引导丝7插入穿刺手柄2的近端,用手指将股动脉按压固定在股骨上,手持穿刺手柄2,其侧通管3侧朝向股动脉近心端,将穿刺针头1与股动脉成45度角刺入直抵股骨,见血液从侧通管3喷出时及时将指引导丝插入,退出穿刺针头1,穿刺成功后可沿指引导丝7植入股动脉鞘。 
本实用新型具备如下优点: 是血管内治疗股动脉穿刺的专用穿刺针,定位准确,操作步骤简单,只需“2步”即可完成穿刺过程,有效地避免穿刺血肿、动脉夹层等并发症的发生

该穿刺针结构简单,生产组装方便,造价低。 
附图说明
图1为本实用新型结构示意图。 
具体实施方式
由图1知,穿刺针头1由不锈钢材料制成,穿刺针头1长度7cm,9号穿刺针粗,侧孔5为长1.5mm的椭圆型,距穿刺针尖4的距离为1cm,穿刺针柄2由透明塑料制成,长度7cm,截面直径4mm,侧通管3 位置紧贴穿刺针头1的尾端,长度1cm,截面直径4mm。
