Abstract

本实用新型涉及一种经皮穿刺导向针，属于医疗器械领域。本经皮穿刺导向针，其特征在于：包括导向管，导向管下端具有破皮针头，上端设置橡胶堵塞，橡胶堵塞通过连接带与导向管连接，导向管外部设置针翼。整个经皮穿刺导向针结构简单合理，通过经皮穿刺导向针的定位、破皮及导向作用，能够使穿刺针准确刺入靶区进行活析，从而提高穿刺准确度及穿刺效率，降低因反复穿刺给患者带来的痛苦。

Description

经皮穿刺导向针
技术领域
本实用新型涉及一种经皮穿刺导向针，属于医疗器械领域。
背景技术
目前，在临床操作中，常用各种穿刺针或者穿刺枪用于肺、肝脏等组织的取材活析，但由于皮肤的韧性及病人的呼吸强度，穿刺针往往不能准确刺入靶区，这样医生在操作时，就需要多次穿刺直至刺准为止，穿刺效率低，在反复多次的穿刺过程中还会带给患者极大的痛苦。目前这一问题还没有得到很好的解决。
实用新型内容
根据以上现有技术中的不足，本实用新型要解决的技术问题是：提供一种结构合理、能够提高穿刺准确度及穿刺效率的经皮穿刺导向针。
本实用新型所述的经皮穿刺导向针，包括导向管，导向管下端具有破皮针头，上端设置橡胶堵塞，橡胶堵塞通过连接带与导向管连接，导向管外部设置针翼。
穿刺前，先找准目标组织，然后打开导向管上端的橡胶堵塞，将经皮穿刺导向针的破皮针头刺入皮肤进行定位，并通过针翼固定，以防止导向针移动，之后，将穿刺针深入导向管中，使穿刺针沿导向管方向准确刺入靶区进行活析。
由于特殊情况导致穿刺位置不准确时，需要将穿刺针从导向管中取出并进行重新穿刺，在穿刺针取出时，必须立即将橡胶堵塞堵在导向管上，从而防止因体内与外界压强不一致所造成的进气或者出血现象。
本实用新型与现有技术相比所具有的有益效果是：
本实用新型结构简单合理，通过经皮穿刺导向针的定位、破皮及导向作用，能够使穿刺针准确刺入靶区进行活析，从而提高穿刺准确度及穿刺效率，降低因反复穿刺给患者带来的痛苦。
附图说明
图1是本实用新型的结构示意图。
图中：1、橡胶堵塞；2、连接带；3、导向管；4、针翼；5、破皮针头。
具体实施方式
下面结合附图对本实用新型的实施例做进一步描述：
如图1所示，经皮穿刺导向针包括导向管3，导向管3下端具有破皮针头5，上端设置橡胶堵塞1，橡胶堵塞1通过连接带2与导向管3连接，导向管3外部设置针翼4。
穿刺前，先找准目标组织，然后打开导向管3上端的橡胶堵塞1，将经皮穿刺导向针的破皮针头5刺入皮肤进行定位，并通过针翼4固定，以防止导向针移动，之后，将穿刺针深入导向管3中，使穿刺针沿导向管3方向准确刺入靶区进行活析。当由于特殊情况导致穿刺位置不准确时，将穿刺针从导向管3中取出进行重新穿刺，在穿刺针取出时，必须立即将橡胶堵塞1堵在导向管3上，从而防止因体内与外界压强不一致所造成的进气或者出血现象。
