Description

Y型带襻鼻胆引流管
技术领域
本发明涉及一种鼻胆引流管，具体地说是Y型带襻鼻胆引流管。
背景技术
十二指肠镜技术(ERCP)是目前治疗胆道系统疾病的重要技术手段，与传统开腹手术相比，具有创伤小、风险低、恢复快等优点。内镜鼻胆管引流是ERCP操作中的一种常规技术，具有以下作用：①通过引流胆汁来治疗梗阻性黄疸、急性性化脓性胆管炎、胆漏等疾病的治疗；②ERCP术后留置鼻胆管能降低术后急性胰腺炎及急性胆管炎的概率；③ERCP后能观察胆汁性状，了解急性化脓性胆管炎恢复情况，判断否存在迟发性胆道出血；④通过鼻胆引流管冲洗，注入敏感性抗生素或止血药，可以促进胆管炎的恢复，预防并治疗迟发性出血。
临床应用的鼻胆引流管包括单猪尾鼻胆引流管及直头鼻胆引流管，其中单猪尾鼻胆管引流管的头端能盘踞扩张的肝内胆管或肝外胆管内，以防止鼻胆管移位，一般适用于肝内或肝外胆管扩张的患者，如果发生引流管外移位，引流管头端部位侧孔会进入胆总管内，肠液及气体可经引流管侧孔反流入胆总管内，引起反流性胆管炎及引流管堵塞等并发症；直头鼻胆管具有十二指肠襻，符合十二指肠与胆总管走形及角度变化，以降低鼻胆管脱出概率，有无肝内外胆管扩张均适用，但是部分肝外胆管较短患者，鼻胆管头端容易移动至肝内胆管深部，导致引流管刺激肝内胆管引起疼痛，且引流效果较差。
发明内容
为克服现有技术的缺点，本发明提供Y型带襻鼻胆引流管。
本发明的技术解决方案是：Y型带襻鼻胆引流管，其特征在于：包括依次相连的直管A、弹性襻管、直管B、L型直管A和L型直管B；
所述的L型直管A和L型直管B的管壁上设有若干个侧孔，两L型直管呈V型，其夹角为45度，外径为5Fr；
所述的直管A、弹性襻管和直管B的外径为7Fr—9Fr。
本发明同现有技术相比具有以下优点：
1、左右肝管内具有引流管，引流效果优于单侧胆管内的引流管；
2、Y型设计可放置引流管内移位，避免了直形头端对于肝内小胆管的刺激；
3、Y型头端胆管壁对胆管的压迫可增加肝内胆管壁与管壁之间的摩擦力，减低胆管外移位的概率；
4、Y型头端拖入胆总管后，由于Y型头端两个头端管壁之间存在张力，可增加十二指肠乳头括约肌及胆总管壁与Y型头端胆管壁支架的摩擦力，防止引流管脱入十二指肠。
5、侧孔仅位于V型胆管侧壁，即使V型管脱入胆总管内，侧孔均位于胆总管内，不会引起肠液的反流。
附图说明
图1是本发明的结构示意图。
图中：1、直管A，2、弹性襻管，3、直管B，4、L型直管A，5、L型直管B，6、侧孔
具体实施方式
本发明的Y型带襻鼻胆引流管，由依次相连的直管A1、弹性襻管2、直管B3、L型直管A4和L型直管B5构成；
所述的L型直管A4和L型直管B5的管壁上设有若干个侧孔6，两L型直管呈V型，其夹角为45度，外径为5Fr；
所述的直管A1、弹性襻管2和直管B3的外径为7Fr—9Fr。
使用时，内镜下分别置入两根导丝，头端分别位于左右肝管内，两根导丝尾端分别置入本发明Y型头端引流管内，在导丝引导下将本发明置入到胆管内，当本发明V型头端胆管完全进入左右肝管内，且V型部与左右肝管分叉处完全贴合，退出导丝及鼻胆管即可。
