一种输尿管鞘及插入人体输尿管的设备 技术领域
本实用新型涉及医疗器械技术领域，尤其涉及一种输尿管鞘及插入人体输尿管的设备。
背景技术
输尿管鞘用于泌尿外科手术中，临床上泌尿外科手术操作前必须在输尿管内置入输尿管鞘从而建立手术通道，在手术过程中通过手术通道导入内窥镜、激光光纤、取石器械或操作线缆等，一些血凝块、细小石块、脓性絮状物也从输尿管鞘中排出。
输尿管鞘通常无法检测肾盂内压力，在手术过程中，肾盂内压力极易增高，容易导致发生尿源性脓毒血症。相关专利中记载有检测肾盂内压力的输尿管鞘，其在输尿鞘管的远端设置测压探头，并将连接测压探头的信号线路设置在输尿鞘管的信号通道内，但是，在实际应用中，由于输尿鞘管的直径限制，此种方式的实现难度极大；并且，在手术过程中，测压探头易受干扰而脱落在肾盂内，造成手术风险。

下面结合附图1～图7，通过具体的实施例及其应用场景对本申请实施例提供的输尿管鞘及插入人体输尿管的设备进行详细地说明。
参照图1，本申请实施例公开了一种输尿管鞘，所公开的输尿管鞘包括管鞘本体100和测压气囊200，其中，管鞘本体100为输尿管鞘的基础构件，能够为测压气囊200提供安装基础，具体地，测压气囊200设于管鞘本体100的远端。
在本实施例中，管鞘本体100设置有延其轴向贯通的第一腔道110，在管鞘本体100的远端插入肾盂处时，第一腔道110可以用于导入内窥镜、激光纤维、取石器械或操作线缆等，肾盂处的血凝块、激光碎石产生的细小石块和脓性絮状物等也可以从第一腔道110向外排出。
除前述的第一腔道110内，本实施例的管鞘本体100还设置有测压腔道120，测压腔道120与测压气囊200相连通，测压腔道120由管鞘本体100的远端向近端延伸，在插入人体肾盂后，使得测压腔道120的近端能够连接测压装置，以实时监测肾盂处压力。
本申请实施例公开的输尿管鞘，管鞘本体100远端设置的测压气囊200能够实时监测肾盂内压力，方便医护人员准确判断并控制手术时间，避免肾盂内压力增高时间过长引发尿源性脓毒血症；与此同时，相较于在管鞘本体100的远端设置测压探头，在管鞘本体的远端设置测压气囊的方式，更易于实施制造，并且，测压气囊在手术过程中不会受干扰而脱离管鞘本体100，能够提升手术过程的安全性。
在本申请实施例中，参照图2～图4，测压气囊200可以设于管鞘本体100的内侧壁；如此设置下，一方面，管鞘本体100能够对测压气囊200起到防护 作用，避免测压气囊200在生产运输过程中受损，另一方面，内设的测压气囊200不会增大管鞘本体100的径向尺寸，使得输尿管鞘易于插入，避免机体受损。当然，测压气囊200还可以设于管鞘本体100的远端壁或管鞘本体100的外侧壁，本申请实施例并不限定测压气囊200的具体设置位置，只要能够准确监测肾盂内压力即可。
一种可选的实施方式中，管鞘本体100设置有安装槽，测压气囊200可以设于安装槽内，例如，安装槽设于管鞘本体100的内侧壁，在测压气囊200位于安装槽内时，在管鞘本体100的轴向方向上，测压气囊200分别与安装槽的槽壁限位配合，从而避免测压气囊200沿管鞘本体100的轴向脱离管鞘本体100，连接稳定性好，保障了手术安全性。
进一步地，测压气囊200可以胶接于安装槽的槽壁，进一步提升测压气囊200与管鞘本体100的稳固性，避免脱离。
发明人在研究过程中发现，相关技术中存在着能够测量肾盂内压力的输尿管鞘，其在输尿管鞘的远端设置测压探头，测压探头多采用胶接的方式粘贴于输尿管鞘的远端，受测压探头尺寸大小、防水性能等影响，此种方式的输尿管鞘存在着生产工艺复杂、良品率低的问题；与此同时，输尿管鞘的前端在插入人体后，受温度变化影响或手术过程的干扰，测压探头易于从输尿管鞘脱离，从而造成手术风险。
基于此种情况，在另一种可选的实施方式中，测压气囊200与管鞘本体100一体成型；如此设置下，不仅方便生产制造，还完全规避了测压气囊200从管鞘本体100的前端脱离的问题，从而保证了输尿管鞘的使用安全。
一种可选的实施方式中，测压气囊200可以为一个，该测压气囊200为环形气囊，测压气囊200沿管鞘本体100的周向延伸设置；当测压气囊200受肾盂腔内液体挤压时，测压气囊200的囊壁挤压气囊内气体，环形结构能够提升测压气囊200受压的均匀性，提升压力检测的准确性。
在另一种可选的实施方式中，输尿管鞘可以包括至少两个测压气囊200，同时，管鞘本体100设置有至少两个与测压气囊200相对应的测压腔道120，测压腔道120的近端能够连接前述的测压装置，以实时监测肾盂处压力；采用多点 监测的方式，能够提升肾盂内压力监测的准确性；与此同时，能够避免某个测压气囊200破损出现的监测失效的情况，保证测压功能的可靠性。
在进一步的技术方案中，输尿管鞘还包括管鞘座300，管鞘座300连接于管鞘本体100的近端，管鞘座300设置有延其轴向贯通的第二腔道340，第二腔道340与第一腔道110相连通，第二腔道340内设置有弹性密封件360，弹性密封件360设置有贯穿弹性密封件360的通孔。
在本申请实施例中，管鞘本体100与管鞘座300可拆卸连接，在向人体输尿管插入管鞘本体100时，管鞘本体100与管鞘座300处于分离状态，以方便医护人员通过内鞘将管鞘本体100置入输尿管内，在管鞘本体100的远端插入到适宜位置时，退出内鞘，再将管鞘座300与管鞘本体100连接，弹性密封件360为高分子材料制成的结构件，例如为橡胶材料，在插入内窥镜时，内窥镜插入部可通过该通孔插入到管鞘本体内，弹性密封件360弹性挤压内窥镜插入部而起到密封作用，以避免血凝块、细小石块和脓性絮状物等经第二腔道340向外泄露。
一种可选的实施方式中，管鞘本体100和管鞘座300螺纹连接而实现可拆卸相连，例如，管鞘本体100设置有外螺纹，管鞘座300设置有内螺纹，管鞘本体100和管鞘座300通过外螺纹和内螺纹的螺纹配合实现螺纹连接，采用螺纹连接具有连接稳定可靠，不易出现松动的情况。
一种可选的实施方式中，管鞘本体100可以设置有测压嘴330，测压嘴330与测压腔道120相连通，前述的测压装置可连接测压嘴330；在另一种可选的实施方式中，管鞘座300可以设置有测压嘴330，测压嘴330与测压腔道120相连通，前述的测压装置可连接测压嘴330；本申请实施例并不限定测压嘴330的具体设置位置，只要能与测压腔道120连通准确测得测压气囊200的气压即可。
一种可选的实施方式中，管鞘本体100可以设置有吸引嘴250，内窥镜插入部的直径小于第一腔道110的口径，使得内窥镜插入部在伸入管鞘本体100内时，管鞘本体100的内侧壁与内窥镜插入部的表面形成间隙，在吸引嘴250连接负压机构的情况下，该间隙可以用于吸取手术过程中的血凝块、细小石块和脓性絮状物。
在另一种可选的实施方式中，管鞘座300可以设置有吸引嘴250，吸引嘴250与第二腔道340连通，进而与第一腔道110连通。需要说明的是，管鞘座300通常为塑料材质制成的结构件，因此，通常将前述的测压嘴330和吸引嘴350设于管鞘座300，具有加工成型方便，易于制造实施的优点。
本申请实施例中，管鞘座300包括连接段310和导向段320，第二腔道340贯通连接段310和导向段320，连接段310与管鞘本体100的近端相连，在管鞘本体100的插入方向上，导向段320的口径逐渐减小；例如，导向段320在管鞘座300的轴向呈锥形，导向段320可以为口径逐渐减小的喇叭状；如此设置下，在插入内窥镜插入部时，喇叭状的导向段能够引导内窥镜插入部插入到管鞘本体100内，提高操作的便捷性。
本申请实施例还公开了一种插入人体输尿管的设备，该设备包括测压表400和前述的输尿管鞘，测压表400连接前述的测压嘴330。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。此外，需要指出的是，本申请实施方式中的方法和装置的范围不限按示出或讨论的顺序来执行功能，还可包括根据所涉及的功能按基本同时的方式或按相反的顺序来执行功能，例如，可以按不同于所描述的次序来执行所描述的方法，并且还可以添加、省去、或组合各种步骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
以上所述，仅为本实用新型的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本实用新型的保护范围之内。
