一种超声针探针和超声针组件
相关申请的交叉引用
本申请要求于2019年11月28日提交中国专利局的申请号为CN201922097242.8、名称为“一种超声针探针和超声针组件”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及一种超声针探针和包括探针的超声针组件，属于人体内使用的医用装置。
背景技术
在超声支气管镜/超声内镜的引导下，穿刺抽吸后获得组织或细胞学样本，是临床上常称的EBUS/EUS检查。EBUS能通过超声定位支气管外病变的具体位置(常规支气管镜只能看到位于气管和支气管内的病变)，并在彩色多普勒的引导下避开血管，通过针吸和活检获得相应部位的细胞和组织，从而达到确诊疾病的目的。EUS检查对胰腺癌的原发肿瘤和局部结节分期的准确性较高。
在EBUS/EUS检查中，通常将探针与超声针管作为超声针组件一起使用，具体的使用步骤包括：将探针插入超声针管中，将组合后的超声针组件通过内窥镜引入患者体内，在超声环境下根据超声图像引导超声针组件到达目标位置，然后将探针从超声针管中取出并开始组织采集。
传统的超声针探针从针管管腔中取出时，医生无法预判探针远端的取出时间，没有及时防范，存在一些隐患。
例如，在没有及时防范的情况下，当探针从针管管腔中完全取出时，由于其为柔性丝构件，远端可能会从管腔中弹出而不受控地接触医务人员或患者，或者有可能从管腔中带出体液或组织，并将这些体液或组织洒在体外，并且，由于内镜操作室光亮条件因人而异，在手术光线条件不足时，更难对探针的取出时间进行预判。
这些隐患增加了医生的操作要求，给临床手术实施带来诸多不便。
有鉴于此，特提出本申请。
发明内容
基于现有技术存在的探针取出时间无法判断等技术问题，本申请提供一种能够在取出过程中，特别是在手术光线条件不足时判断探针取出部分距离远端的距离从而预判探针的取出时间的超声针探针，该超声针探针包括：配置成操控的近端，配置成插入超声针管的远端，以及在近端和远端之间延伸的细长柔性本体；所述细长柔性本体的远端外表面上通过激光形成至少一个凸起。
优选地，所述凸起通过在所述细长柔性本体远端外表面上激光熔融表面材料并挤压形成。
优选地，所述凸起通过在所述细长柔性本体远端外表面上激光焊接固定形状材料形成。
优选地，所述细长柔性本体为镍钛合金针体。
优选地，所述细长柔性本体的远端外表面上形成多个所述凸起，多个所述凸起形成沿细长柔性本体外表面周向环绕的标记带，沿所述细长柔性本体轴向方向具有若干间隔分布的标记带。
优选地，一个以上的标记带构成一组标记带组，沿所述细长柔性本体轴向方向具有若干间隔分布的标记带组。
优选地，每个标记带组包括的标记带个数从细长柔性本体的远端朝向近端递增，相邻标记带组之间的间隔从细长柔性本体的远端朝向近端递增。
优选地，相邻凸起之间的间隔为0.1mm-0.5mm，所述凸起具有0.01mm-0.05mm的高度。
优选地，所述凸起的形状为矩形、圆形、椭圆形、梯形或十字形。
此外，本申请还提供了包括该超声针探针的超声针组件，超声针组件包括具有内部管腔的超声针管和所述超声针探针，所述超声针探针可操作地位于所述超声针管的管腔中。
基于上述技术方案，本申请具有如下优点：
本申请通过在超声针探针远端外表面上激光处理形成凸起，使得在EBUS/EUS检查过程中取出探针时，能够提前判断其远端何时从超声针管中完全取出，从而及时采取必要的措施，避免手术过程中隐患的出现。
本申请的有益效果具体体现在：首先，通过激光焊接形成的凸起具有与超声针探针本体不同的颜色，当即将完全取出探针时，在光线条件充足时可目视判断当前取出部分距离远端的距离从而预判探针取出时间；并且，通过激光焊接形成的凸起能够通过触觉感知，从而即使在手术光线条件不足时，也可以通过触摸针体判断当前取出部分距离远端的距离；进一步地，在优选的技术方案中，通过凸起形成的图案对距离远端具体的尺寸进行了标识，使得判断结果更精确，更加便于临床的使用，操作方便简单；此外，在对精密度要求极高的微创手术器械加工过程中，为了解决镍钛合金材料加工难度大这一技术问题，研发人员对凸起的加工方法进行优化，通过采用激光焊接和激光熔融等方式不仅解决如何在镍钛合金上设置凸起的问题，而且凸起的尺寸、凸起间距离和凸起高度可控，实现在镍钛合金材质表面形成形态精确可控的凸起结构，便于制定人体触感可接受的限度。
综上，本申请提供了一种便于临床使用时能够预判取出时间的超声针探针和具有该探针的超声针组件，在临床使用中提高了手术的安全性。

超声针管的近端为探针接合端3，使用时可通过接合端3插入或取出超声针探针1。具体的使用步骤包括：在插入人体之前，将组件组合，通过接合端3插入超声针探针1；将组合后的组件插入人体，在超声环境下根据超声图像引导超声针组件到达目标位置，然后将超声针探针1通过接合端3从超声针管中取出并开始组织采集。
其中，超声针探针1包括配置成操作的近端和配置成插入针管的远端2以及在近端和远端2之间延伸的细长柔性本体，其近端包括操作手柄便于探针1的插入和取出，其远端2包括圆形头部。其中，超声针探针1的细长柔性本体优选地为由镍钛合金材料形成的针状本体。
为了在取出探针1的过程中能够准确判断取出位置，在探针1的远端通过激光焊接形成了凸起5，凸起5的局部放大图如图2所示。
在一个实施例中，凸起5可通过在细长柔性本体远端外表面上激光熔融表面材料并挤压形成。其具体步骤包括，通过激光对需要形成凸起的区域进行环状打点作业，将外周材料熔融，然后挤压中间材料成圆形凸起。该圆形凸起的直径为0.1mm，具有突出外表面0.02mm的高度，且相邻凸起之间的距离为0.2mm，并且通过挤压形成的凸起具有与细长柔性本体不同的颜色。
在其他相似的实施例中，挤压中间材料形成的凸起形状可以是矩形、椭圆形、梯形或十字形等类似形状，凸起的直径和边长等尺寸可选为0.05-0.3mm之间的任意尺寸，凸起突出外表面的高度可选为0.01-0.05mm之间的任意尺寸，相邻凸起之间的间隔可选为0.1-0.5mm之间的任意尺寸。

如图4示出了本实施例中超声针探针1的本体远端部分局部视图，其中，第一标记带组21由两个标记带形成，第二标记带组22由三个标记带形成，……，第N标记带组由N个标记带形成。
在一个实施例中，第一标记带组21距离远端的距离与其余相邻组标记带之间的距离相等，该等距离例如可以是5cm、10cm，……，从而可以通过标记带的个数指示各组标记带与远端的距离。在其他实施例中，该距离可以是不等的，例如从远端朝向近端递增，例如，第一标记带组21距离远端的距离为5cm，第一标记带组21与第二标记带组22之间的距离为10cm，第二标记带组22与第三标记带组之间的距离为15cm，以此类推。
具体的标记带组的数量和各标记带组之间的间隔数值是可以选择的，为了便于医生按照使用习惯选择，实际使用中，可提供一组探针，医生可根据需要从一组探针中选择具有合适的尺寸标记的探针使用。
如图5所示的该实施例中超声针组件组合时远端示意图，图中示出了当将超声针组件 组合时，超声针探针1通过探针接合端3插入超声针管，此时，探针1的远端位于针管尖端4的内部，从而能够在超声针组件插入体内的过程中防止不需要的组织进入针管并给超声针提供合适的刚度。
最后应说明的是：以上各实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述各实施例对本申请进行了详细的说明，但本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
