The invention relates to a drainage tube, in particular to a nasobiliary and pancreatic internal and external drainage tube with a connecting line. The drainage tube comprises an external nasobiliary drainage tube, a drainage tube in the pancreatic duct and a connecting line; the external nasobiliary drainage tube is a single channel drainage tube with an amiba spiral at the front end and a side hole on the side wall and a cone at the head end; the drainage tube in the pancreatic duct is a straight single channel drainage tube with a side hole on the wall, a cone at the head end, and a side wing and a groove on the wall of the tail tube. The tail side wall of the duct passes through the end of the external nasobiliary drainage tube, and the front end of the connecting line is a movable loop. The ring is sleeved in the groove. The tail end of the connecting line is tightened to connect the tail of the drainage tube in the pancreatic duct with the external nasobiliary drainage tube. The invention can be used to intubate the pancreatic duct first, and the connection line of the nasobiliary external drainage tube can make the pancreatic duct drainage tube fixed on the nasobiliary external drainage tube, which can prevent the internal or external displacement of the drainage tube in the pancreatic duct. After treatment, when the nasobiliary external drainage tube is removed, the drainage tube in the pancreatic duct can be removed accordingly.

带连接线的鼻胆胰内外引流管
本专利技术涉及一种引流管,具体是一种带连接线的鼻胆胰内外引流管。
技术介绍
随着内镜技术的不断发展及其附件的不断完善,目前十二指肠镜技术(ERCP)已然成为治疗肝胆胰疾病的重要措施,包括胆总管结石、胆管损伤、胆管狭窄、肝移植术后胆道并发症等。该技术与传统开腹手术相比,具有创伤小、安全系数高、恢复快等优点。其直视下观察,能发觉常规肝胆脾胰CT、超声以及磁共振等检查所不能发现的肝胆胰疾病,同时进行治疗,如十二指肠乳头炎、乳头狭窄、乳头旁憩室、十二指肠乳头过长、胆胰合流异常等。但是ERCP术后存在急性胆管炎、急性胰腺炎、迟发型出血等并发症。内镜鼻胆管引流是ERCP操作中的一种常规技术,可直接应用于梗阻性黄疸、急性化脓性胆管炎、胆漏等疾病的治疗;术后留置鼻胆管能充分引流胆汁,降低胆道压力,具有降低术后胰腺炎及胆管炎的概率,同时能观察胆汁性状及流出情况,对于急性化脓性胆管炎、迟发性胆道出血等,可经鼻胆引流管注入敏感性抗生素或止血药,临床效果显著。内镜下胰管内引流是ERCP操作的另一种常规技术,放置胰管内引流管可用于治疗急性胰腺炎、胰腺脓肿等疾病, ...
【技术保护点】
1.带连接线的鼻胆胰内外引流管,其特征在于,所述引流管包括鼻胆外引流管、胰管内引流管、连接线;鼻胆外引流管为单通道引流管,前端呈阿米巴螺旋状;胰管内引流管为直型单通道引流管,尾部管壁上设有侧翼和凹槽;连接线从鼻胆外引流管尾端侧壁穿过,经鼻胆外引流管头端穿出,且连接线前端为活动的线环,线环套在凹槽处,拉紧连接线尾端则收紧线环使胰管内引流管尾部与鼻胆外引流管相连。
