Description

一种三棱型排石防逆流方便取出型输尿管支架
技术领域
本发明涉及输尿管支架技术领域，具体而言，涉及一种三棱型排石防逆流方便取出型输尿管支架。
背景技术
输尿管支架在泌尿外科手术中应用极为广泛，适用于肾结石、输尿管结石、肾积水、肾移植、肾及输尿管良性肿瘤等上述尿路手术以及碎石机碎石、输尿管狭窄的扩张等治疗过程中，它植入输尿管后能起到引流尿液、防止输尿管狭窄和粘连堵塞等作用,其两端弯曲呈环状似英文字母J而又称双J管，使用时，输尿管支架一端放置于肾盂，支架本体置于输尿管内，另一端放置于膀胱,根据不同病情，双J管留置的时间也不同，从2-4周到1-3月不等，除肿瘤，输尿管狭窄等特殊疾病，大部分留置约2-4周,留置一段时间后需从体内取出。
传统取管需在手术床上取截石位通过刚性膀胱镜通过尿道进入膀胱直视下钳夹双“J”管的末端拔出,由于留置时间较长，输尿管支架长时间与输尿管内壁接触，在拔出时会增加患者痛苦(尤其男性患者)，拔管后易出现尿路刺激症状，部分患者发生尿道损伤而出现血尿,会对患者产生不同程度的损伤，所以我们提出了一种三棱型排石防逆流方便取出型输尿管支架，以解决上述问题。
发明内容
为了弥补以上不足，本发明提供了一种克服上述技术问题或至少部分地解决上述问题的一种三棱型排石防逆流方便取出型输尿管支架。
