中国授权实用新型专利 （ZL200820051521.X) 公开了一种连发式痔疮吸扎器， 包 括本体，还包括设于本体前端的管体及依次套于管体上的多个被拉伸的胶圈、置于管体 后且与管体内腔相通的负压吸引接头、设于本体上的胶圈弹出装置，所述管体前端套有 与管体内腔连通的发射头，所述胶圈套于发射头上； 所述胶圈弹出装置包括至少一根牵 引线及设于本体内的绕线装置，所述牵引线的前端缠绕在绕线装置上，所述牵引线的尾 端穿过管体内并经由发射头管口返折， 且沿发射头外壁与所述胶圈通过牵引机构相连 接。
上述痔疮吸扎器（又称痔疮套扎器） 以及国内外其他类型的痔疮套扎器， 都有一个 共同的特点， 即它们均采用 "胶圈"作为套扎于痔疮根部的基本材料； 而制作该胶圈可 选用的原料包括天然橡胶、 乳胶或硅胶等。
痔疮胶圈套扎术的临床疗效与 "胶圈的内孔径"和 "胶圈的弹性回缩力"两项技术 指标直接相关。而利用胶圈作为套扎材料具有一些固有的缺点： ①由于天然橡胶（或乳 胶、硅胶等）的固有特性， 限制了胶圈的内孔径不能无限小， 一般只能制成 2.0〜2.5mm (至少不得小于 1.5mm)，否则套扎拉伸时极易断裂。这就意味着在直径 2.0〜2.5mm (至 少不小于 1.5mm) 的尺寸范围内， 被套扎的痔疮组织将不受到任何弹性回缩力的作用， 最终组织坏死脱落后形成的溃疡范围也在 2.0〜2.5mm (至少不小于 1.5mm) 左右； ② 当胶圈以拉伸状态安装在套扎器上时， 随着时间延长， 容易逐渐发生疲劳而使内孔径变 大； ③受气候、 环境等因素影响， 胶圈容易随时间发生老化， 从而使弹性回缩力变弱。
由于以上因素的影响， 将可能导致以下后果： ①术后短期内发生胶圈滑脱， 致使治 疗失败； ②引起术后出血并发症 （据统计， 痔疮胶圈套扎术后的出血率为 2 %〜5 % )； ③痔块坏死不完全， 溃疡面愈合延迟， 影响疗效。 发明内容
本发明的一个目的是提供一种套扎器中的弹力线设置方法，可方便调节弹力线的弹 出和收紧。
本发明的上述目的通过以下技术措施来实现： 一种套扎器中的弹力线设置方法，沿 套扎器的枪管外壁加设至少一根弹力线，弹力线的前端形成孔径可调的环套套于枪管前 端的外壁上； 将套扎器上的牵引线与弹力线的环套相连接， 拉动牵引线时， 牵引线带动 环套向枪管管口移动直至于管口处脱出； 向前抵住弹力线前端环套的着力部位， 同时向 后抽拉弹力线尾端， 此两个作用力对抗牵引使得弹力线前端的环套孔径逐渐缩小。
本发明以弹力线代替胶圈， 弹力线前端的环套在被牵引线拉动并从枪管管口弹出 后， 抽拉弹力线尾端可使环套的孔径逐渐缩小， 直至缩小至接近于零， 因此可以有效调 节弹力线的环套孔径。
本发明所述弹力线前端的孔径可调的环套通过打活结而形成，环套的打结点为抵住 环套的着力部位； 或弹力线前端的孔径可调的环套通过弹力线穿过一个固线珠形成， 固 线珠为抵住环套的着力部位。
作为本发明的一种实施方式，在所述弹力线上套设推线管，将弹力线的尾端穿过推 线管后使其尾端卡扣于推线管的后端管口处；施力于推线管使其前端管口抵住环套的着 力部位， 同时向后抽拉弹力线尾端， 此两力的对抗牵引即可使环套的孔径逐渐缩小。
本发明通过在推线管的尾端开设卡槽并在卡槽内设置可拨动的卡凸以实现对推线 管的定位。
本发明的另一个目的是提供一种自动弹力线套扎器。本套扎器采用弹力线代替现有 技术中的套扎胶圈， 可以有效调节弹力线的套扎孔径。
本发明的上述目的通过以下技术方案来实现： 一种自动弹力线套扎器， 包括枪管、 枪体和牵引线，所述牵引线穿过枪管且其后端定位在枪体内，牵引线的前端则伸出枪管 后返折在枪管前端的外壁上； 其特征在于： 还包括至少一根弹力线， 所述弹力线沿着枪 管的外壁设置，弹力线的前端形成孔径可调的环套套于枪管前端的外壁上，所述环套与 牵引线的前端相连接； 向后拉动牵引线，牵引线带动环套向枪管管口移动直至于管口处 脱出； 向前抵住弹力线前端环套的着力部位， 同时向后抽拉弹力线尾端， 此两力对抗牵 引使得环套的孔径逐渐缩小。
本发明通过牵引线拉动环套使其套扎在目标组织上， 由于可使环套的孔径逐渐缩 小， 因此能够实现对目标组织更为紧固的套扎； 当目标组织坏死脱落后， 溃疡面极小， 降低了术后并发出血的几率，同时也避免了前述关于胶圈套扎所固有的其他缺点如术后 短期内胶圈滑脱致治疗失败、 组织坏死不完全致溃疡面愈合延迟等。
本发明所述的自动弹力线套扎器还包括用于抵住所述着力部位的推线管，每个弹力 线套有一个推线管，所述弹力线的尾端穿过推线管且卡扣于推线管的后端管口，所述推 线管的后部插装在枪体内。

作为本发明的另一种实施方式， 所述推线管的后部经推线管弹出机构插装在枪体 内，所述推线管弹出机构包括一个推线管释放轮和至少一个长条形的推线管限位板， 每 个所述推线管限位板的前端部均对应卡接限位一个推线管，每个推线管限位板沿纵向并 列排布并经其中部共同铰接于枪体内壁；所述推线管释放轮的圆周轮面上交错分布至少 一个用于撬动推线管限位板的凸块，每个凸块随推线管释放轮的转动均对应一个位于轮 面上方的推线管限位板， 转动推线管释放轮使凸块顶起与之对应推线管限位板的后端 部，使该推线管限位板绕其铰接轴转动，推线管限位板前端部下落而撤销对推线管的限 位， 推线管在弹力线的回复力作用下弹出。
上述推线管弹出机构组成零部件少， 零部件的结构简单， 制作成本低； 每个推线管 上无需设置位置不同的卡槽， 降低了制作难度； 而且， 当弹出推线管时， 通过转动推线 管释放轮使其上的凸块顶起推线管限位板以撤销对推线管的限位，施加于推线管释放轮 上的作用力不会影响把持的稳定性， 操作方便。
本发明所述推线管限位板前端部设有卡块，推线管后端管口插接有与弹力线尾端相 连的卡接头， 所述卡接头上开有限位槽， 所述卡块卡接于所述限位槽中。

与现有技术相比， 本发明在具体使用中具有如下显著的优势：

(2)由于套扎极为紧固， 不会滑脱， 因而在同一水平面的肠壁上所套扎的位点可以增 多 （可套扎 6〜8个位点， 既往的任何套扎方法一般只套扎 3〜4个位点）， 这大大地提 高了上提肛垫 （或上提脱垂的直肠粘膜） 的效果。
(3)弹力线不易老化和疲劳， 使用寿命长， 可提高套扎效果。
(4)枪管和设置在枪管上的推线管、 推线管固定夹、 牵引线旋钮、 弹力线、 牵引线等 可以组合装配为一个可脱离枪体的枪管组件，通过枪管可很方便的将这些枪管组件作为 一个整体拆卸安装在枪体上， 能够实现一个枪体与多个枪管组件的配套使用，增加了可 套扎痔疮的数量， 当需要套扎多于一个枪管组件上所设置的弹力线数量的痔疮时，仅需 要更换枪管组件即可， 而无需更换整个套扎器， 因此降低了患者的经济成本。 (5)本发明中分支牵引线沿发射头管口呈对称性分布， 可以为弹力线提供均匀拉力， 使得环套能够顺利地套在目标组织上。
(6)本发明简单方便， 省时省力， 实用性强， 不仅适用于治疗痔疮， 还可以深入体内 实现对直肠脱垂、 直肠息肉或其它适用的肛肠疾病的治疗；
(7)本发明采用推线管弹出机构当弹出推线管时，通过转动推线管释放轮使其上的凸 块顶起推线管限位板以撤销对推线管的限位，施加于推线管释放轮上的作用力不会影响 把持的稳定性， 操作方便。 附图说明

实施例 1
如图 1〜9所示的一种套扎器中的弹力线设置方法， 沿套扎器的枪管 3外壁加设至 少一根弹力线， 本实施例中设置三根， 在每根弹力线 2上套设推线管 1， 将弹力线 2的 尾端穿过推线管 1并打成结 28使其尾端卡扣于推线管 1后端的管口处， 弹力线 2的前 端则形成孔径可调的环套 21套于枪管 3前端的外管壁上，此时弹力线 2处于拉伸状态; 将套扎器上的牵引线穿过枪管，且使牵引线的前端伸出枪管后返折在枪管前端的外管壁 上， 牵引线的后端则定位在相应结构上； 在牵引线的前端上设置牵引块且位于环套 21 的后方， 通过牵引块卡合环套实现牵引线与环套的连接和联动； 在本实施例中， 牵引块 是牵引线自身所打成的结 20。环套 21是由弹力线的一端按常规方法打成的可调节的活 结 25形成， 环套的打结点为抵住环套的着力部位， 拉动牵引线时， 牵引线带动环套向 枪管管口移动直至于管口脱出；通过施力于推线管使其前端管口抵住环套的打结点， 同 时向后抽拉弹力线的尾端， 两作用力的对抗牵引使得弹力线前端的环套孔径逐渐缩小。
在其它实施例中， 如图 10所示，弹力线 2前端的孔径可调的环套 21还可以通过弹 力线 2穿过一个固线珠 27形成， 固线珠 27为抵住环套 21的着力部位； 具体是弹力线 2的尾端穿过推线管 1并打成结 28使其尾端卡扣于推线管 1的后端管口处， 弹力线 2 的前端穿出推线管的前端管口再穿过固线珠 27的其中一个孔道 29， 该孔道 29内设有 可以卡紧弹力线 2的机构且只允许弹力线单向抽拉，这种机构可以采用现有技术手段来 实现；然后， 弹力线 2再反折穿过固线珠上的另一个孔道 32后形成结 33而卡合在该孔 道 32的孔口处。
通过在推线管 1尾端开设卡槽 11并在卡槽 11内设置可拨动的卡凸 7实现推线管 1 的定位。 具体是在推线管 1的后部开设卡槽 11并使推线管 1的后部穿入枪体 5内腔； 在枪体 5内壁上设置沿其横向延伸的滑轨 12， 在滑轨 12上安装推线管释放钮 13使其 可沿滑轨 12移动， 并将推线管释放钮 13上的卡凸 7卡于推线管 1的卡槽 11中以定位 推线管 1 ; 按压推线管释放钮 13使卡凸 7脱离卡槽 11， 此时即可卸除推线管 1和弹力 线 2。 推线管释放钮 13由弹性臂 8、 滑块 9和按压面板 10组成； 将滑块 9和弹性臂 8 的一端分别连接在按压面板 10的背面上，滑块 9滑动安装在滑轨 12上， 卡凸 7设置在 滑块 9的顶面上， 推线管 1的卡槽 11朝向下设置与卡凸 7相对应， 将弹性臂 8的另一 端作为弹性臂的下端抵触在枪体 5内壁上，使弹性臂 8的原始长度大于滑块 9的长度以 便推动按压面板 10使弹性臂 8发生形变时滑块 9沿滑轨 12移动从而将卡凸 7脱出卡槽 11 ; 撤销作用力后， 推线管释放钮 13回复原位。
上述方法可应用在医疗器械上， 使用上述弹力线设置方法的自动弹力线套扎器，包 括枪管 3、 发射头 31、 枪体 5、 枪柄 22、 牵引线、 设于枪体 5内后部的绕线轮 6、 与枪 管 3连通的负压接头 40、至少一根弹力线 2和推线管 1、设置在枪柄侧面上的负压释放 开关 30; 套扎器以上各组成部件均采用医用高分子材料制成； 其中， 枪体 5和枪柄 22 具有连接成一体的壳体， 该壳体由两半壳体对接而成。弹力线的横截面为圆形， 直径为 1.0〜3.0mm， 由内、 外两层构成； 内层 （弹力条）为条带状具有高度弹性的特殊高分子 材料； 外层 （包裹层） 为网状编织层， 包裹在内层表面， 亦由特殊的高分子材料制作， 能随内层弹力条的拉伸而舒张； 弹力线这种特殊的双层结构使其不仅具有良好的弹性， 而且能够承受强大的轴向拉力而不断裂，当处于拉伸状态的弹力线环套被套于目标组织 上时还能被进一步抽紧而缩小孔径； 此外弹力线也不易老化和疲劳， 使用寿命长， 可提 高套扎效果。
发射头 31被安装在枪管 3的前端； 牵引线穿过发射头 31、 枪管 3和枪体 5内且其 后端缠绕在绕线轮 6上以实现牵引线后端的定位， 前端则伸出发射头 31管口返折在发 射头 31的外壁上； 牵引线也由特殊的医用高分子材料制成， 能够承受强大的轴向拉力 而不断裂； 推线管 1沿着枪管 3的外壁安装设置， 在本实施例中， 推线管采用三根， 并 列排布； 推线管 1的后半部穿过枪体 5内的定位管 50并通过推线管释放机构安装在枪 体 5内； 弹力线 2穿过推线管 1且其尾端卡扣于推线管 1后端的管口， 弹力线 2的尾端 形成结 28卡在推线管 1的后端管口， 也可以设置卡块卡在推线管 1的后端管口， 弹力 线 2的前端则穿出推线管 1的前端管口并稍作抽拉使其保持拉伸状态，然后打活结形成 孔径可调的环套 21套于发射头 31的外管壁上； 牵引线的前端上设有与环套 21相卡合 的牵引块， 在本实施例中， 牵引块是由牵引线自身打结形成， 牵引线位于环套 21和发 射头 31外壁之间， 且牵引块位于环套 21的后方。 转动绕线轮 6时， 牵引线向后运动， 带动返折于发射头管壁上的牵引线和牵引块沿管壁向前移动， 牵引块再带动环套 21 向 发射头 31管口移动直至从管口脱出。 在本实施例中， 牵引线由主牵引线和两根分支牵 引线 26相连而成，主牵引线的另一端缠绕在绕线轮上， 分支牵引线 26的另一端伸出发 射头 31且沿发射头管口呈对称性分布以便为环套 21提供均匀拉力， 使环套 21顺利脱 离发射头 31管口并套于目标组织上。
在本实施例中，推线管释放机构包括三条滑轨 12和三个推线管释放钮 13 ;滑轨 12 沿枪体 5内腔横向设于枪体 5的内壁上；推线管释放钮 13滑动安装在滑轨 12上； 推线 管释放钮 13上设有卡凸 7， 推线管 1的后部设有卡槽 11， 卡凸 7卡于卡槽 11中； 三个 推线管释放钮上的卡凸设置位置不同 （沿横向错开）， 每个推线管释放钮 13上的卡凸 7 与相对应位置上的推线管 1上的其中一个卡槽 11配合； 而为了生产和安装方便， 每个 推线管 1上均设有三个卡槽 11， 即仅与推线管释放钮 13上的卡凸 7相对应的卡槽 11 被利用。 推线管释放钮 13由按压面板 10、 长形体的弹性臂 8和滑块 9一体制成， 滑块 9和弹性臂 8的一端分别连接在按压面板 10的背面上， 且滑块位于弹性臂的上方， 滑 块 9的两侧设有凸沿，滑轨 12上具有凹槽，滑块 9的凸沿位于滑轨 12的凹槽中实现滑 块和滑轨之间的滑动连接； 卡凸 7位于滑块 9的顶面上， 推线管 1的卡槽 11朝向下与 卡凸 7相对应； 弹性臂 8的另一端作为弹性臂的下端抵触在枪体 5 内壁上， 弹性臂 8 的原始长度大于滑块 9的长度， 按压面板位于枪体的侧面上用于接受按压施力。 其中， 弹性臂 8是弯折状片体， 在枪体 5内壁上沿其长度方向设有限位凸条 （图中未画出）， 限位凸条位于弹性臂 8的下方，弹性臂 8的后端卡在限位凸条上。当没有施力于按压面 板 10时， 弹性臂的弹性回复力将卡凸 7顶在卡槽 11内； 当按动按压面板 10时， 弹性 臂 8被压缩， 同时限位凸条限位弹性臂 8的后端， 滑块 9沿着滑轨 12移动， 使卡凸 7 从卡槽 11 内脱出， 此时即解除推线管 1 的定位； 当撤销作用力时， 推线管释放钮 13 回复至原位。
在枪体 5和枪柄 22内设有负压管路，负压管路由位于枪体内的第一负压管 23和位 于枪柄内的第二负压管 24连通而成； 其中， 第一负压管 23与枪管 3连通， 绕线轮 6 位于第一负压管 23的后方， 牵引线经发射头 31、 枪管 3再经第一负压管 23引出后缠 绕在绕线轮上；第二负压管 24上设有负压释放孔， 负压释放开关 30上设有用于堵塞负 压释放孔的封堵块； 第二负压管 24的末端为负压接头 40， 当负压接头 40连接的负压 抽吸系统开启， 同时负压释放开关 30为关闭状态即封堵块堵塞住负压释放孔时， 可使 整个负压管路、 枪管 3、 发射头 31的内腔体产生足够负压， 从而使发射头 31口端能够 吸住目标组织； 当套扎操作完成后， 打开负压释放开关 30使封堵块离开负压释放孔， 消除上述管路内的负压， 以释放被吸住的目标组织。
以本发明实施例 1 自动弹力线套扎器用作套扎痔疮组织的医疗器具为例，其使用的 工作过程如下： 先将负压接头接通负压抽吸系统， 并关闭负压释放开关； 用手握持住手 柄， 将发射头管口对准痔疮组织 （或其他目标组织）； 开启负压抽吸系统， 痔疮组织便 被吸入发射头管口内； 此时再用手指拨动绕线轮， 由此牵动牵引线向后移动， 在牵引力 作用下，沿发射头管壁分布的牵引线与牵引块则向发射头管口移动， 并带动弹力线的环 套一起向管口移动， 直至环套从发射头管口脱出， 与此同时将痔疮组织套住； 打开负压 释放开关， 消除负压并释放被套扎的痔疮组织； 按压推线管释放钮， 释放推线管， 将推 线管抽出； 施力于推线管以使推线管前端管口抵住环套的打结部位和该处的痔疮组织， 然后同时用力抽拉推线管后端管口的弹力线，两者的对抗牵引使弹力线进一步收紧并使 环套的孔径更为缩小（此时环套孔径可缩至接近于零），从而将痔疮组织进一步扎紧， 便 完成了一次套扎操作。同法进行下一个部位的套扎。 以此类推可以连续进行 3次或更多 次的套扎操作。
自动弹力线套扎器由于实现了对痔疮组织的紧固套扎， 故当痔疮脱落后，溃疡面极 小， 降低了痔疮套扎术后发生出血的几率， 同时也避免了既往胶圈套扎所固有的其他缺 点 （如术后短期内胶圈滑脱致治疗失败； 痔块坏死不完全致溃疡面愈合延迟等）。
检验本发明套扎器的气密性时，将套扎器负压接头接驳外源负压抽吸系统， 同时关 闭排气孔开关并堵塞发射头口端， 开启负压抽吸系统， 至负压表指针至少指向 -0.08MPa 以上为合格。
实施例 2
本实施例 2为本发明的优先实施方式， 与实施例 1 的主要区别之处在于： 枪管 3 采用拆卸式装在枪体 5上， 牵引线 36通过转接传动机构连接位于枪体 5后部的驱动轮
61上，需要拉动牵引线时，是由驱动轮 61通过转接传动机构向后拉动牵引线（见图 11 18 所示）。 同时， 推线管采用推线管弹出机构插装在枪体内 （见图 19 31所示）。
在本实施例中， 如图 11 18所示， 转接传动机构包括牵引线旋钮 34、 转接轴 35和 传动带 37，转接轴 35沿横向设置在枪体 5的内前端，传动带 37的后端绕于位于枪体 5 内后部驱动轮 61上，传动带 37的前端则套于转接轴 35的内端上，牵引线旋钮 34套接 在转接轴 35的外端上， 牵引线旋钮 34与转接轴 35的套接部位相啮合， 牵引线的后端 绕在牵引线旋钮 34的前端上，牵引线旋钮 34的后端伸出枪体 5以便对其进行装卸，顺 时针拨动驱动轮 61， 通过传动带带动转接轴转动， 进而使牵引线旋钮旋转绕线， 从而 向后拉动牵引线以带动环套向枪管管口移动直至于管口处脱出。
在枪管 3外壁上设置卡扣结构， 卡扣结构由推线管固定夹 38和设于枪管 3外壁上 的至少一个凹槽 39组成， 推线管固定夹 38呈 H形， 即推线管固定夹 38由横板 43和 一对竖板 44组成， 横板 43的上板面具有至少一个卡口， 凹槽 39与卡口上下相对应； 凹槽 39的两侧设有卡槽，推线管固定夹 38的侧板上端设有卡勾， 卡勾卡合在卡槽中而 将推线管固定夹 38安装在枪管 3上， 并使凹槽与卡口对合以夹持推线管， 以便在枪管 安装于枪体上之前对推线管进行固定。 在推线管固定夹 38的其中一竖板外壁上设有 C 形夹口 47， C形夹口 47的开口朝外， 牵引线旋钮 34由开口嵌入 C形夹口 47中夹紧， 以便在枪管安装于枪体上之前对牵引线旋钮进行固定。这样， 上述枪管和设置在枪管上 的推线管、 弹力线、推线管固定夹、 牵引线旋钮、 牵引线等可以组合装配为一个枪管组 件。
枪管 3 的后端具有上下并排的两个通孔， 位于上方的通孔是呈管形的插接头 48， 枪体 5内负压管路 60的一端伸出枪体 5的前端并设有插接座 62， 插接头 48密封插装 在插接座 62中而使枪管 3与负压管路 60连通， 负压管路 60由位于枪体 5内的第一负 压管 23和位于枪柄内的第二负压管 24连通而成，第一负压管 23的后端封闭， 具体是: 插接头 48与第一负压管 23连通， 驱动轮 61位于第一负压管 23的后方， 第一负压管 23位于传动带 37的上方， 负压管路 60处于传送带的旁侧。 位于下方的通孔由胶堵 51 封堵， 胶堵 51上开有仅供牵引线通过的小孔 52， 枪体 5的前端开有与用于牵引线旋钮 34穿过的开孔相贯通的走线槽 53，牵引线穿过胶堵 51的小孔 52并沿走线槽 53直行而 绕于牵引线旋钮 34上。 在枪体 5内壁上设有用于张紧传动带 37的张紧柱 58， 张紧柱 58分布在传动带 37的周侧， 张紧柱 58支承传动带 37以使动力稳定传输。 因此， 本实 施例的负压管路与牵弓 I线走线路径是完全分离的。
枪管 3的后端设有具有卡勾的卡块 54， 枪体 5的前端设有卡孔 55和推压件， 卡孔 55位于枪体 5的前端面上并与枪体内相通， 卡块 54的卡勾卡于卡孔 55中， 推压件位 于枪管上的下方通孔的旁侧，枪体 5前端的侧壁上设置与枪体内相通的开孔，推压件位 于开孔中， 推压件由弹力臂 56和连接在其下端上的推块 57组成， 弹力臂 56的上端连 接在开孔的上孔沿上以便为推块 57提供回复力， 推块 57与卡块 54的卡勾相对应， 向 枪体内推压推块使得推块拨动卡勾进而使卡块脱离卡孔， 实现枪管拆卸式插装在枪体 上。这样， 通过枪管后端的上述结构， 就可以很方便的将枪管组件作为一个整体拆卸或 安装在枪体上， 实现一个枪体与多个枪管组件的配套使用。
本实施例中， 如图 19 31 所示， 推线管弹出机构包括设于枪体上的推线管释放轮 14和至少一个长条形的推线管限位板 16， 在本实施例中， 推线管 1为三个， 沿着枪管 3 的外壁安装设置， 并列排布； 相应地， 推线管限位板 16也为三个， 每个推线管限位 板 16的前端部均对应卡接限位一个推线管 1， 推线管释放轮 14可转动安装在枪体 5的 下部，三个推线管限位板 16沿纵向并列排布并经其中部共同铰接于套扎器枪体 5内壁， 推线管释放轮 14的轮面 17上交错分布至少一个用于撬动推线管限位板 16的凸块 18， 在本实施例中， 凸块 18为三个， 每个凸块 18随推线管释放轮 14的转动均对应一个位 于轮面上方的推线管限位板 16， 转动推线管释放轮 14使凸块 18顶起与之对应推线管 限位板 16的后端部， 并使该推线管限位板 16绕其铰接轴 67转动， 同时推线管限位板 16前端部下落而撤销对推线管 1的限位， 推线管 1在弹力线 2的回复力作用下弹出。 弹力线 2的前端打活结形成孔径可调的环套 21 并套于自动弹力线套扎器的发射头 31 上， 使用弹出后推线管的前端头 68可抵住弹力线 2的打结部位 69， 进行套扎操作。
推线管限位板 16前端部设有卡块 19， 推线管 1后端管口插接有与弹力线 2尾端相 连的卡接头 41， 卡接头 41上开有限位槽 42， 卡块 19卡接于限位槽 42中而将推线管 1 的后部限位在枪体 5内。卡接头 41主要由插接于推线管 1后端管口内呈柱体的内段 45 和伸出推线管 1外段 46组成， 限位槽 42以环形状开设在呈纺锤形的外段 46上， 卡块 19的上端设有卡槽 49， 卡槽 49的槽口向上且其轮廓与限位槽 42的槽底轮廓相适应， 本实施例中， 限位槽 42的槽底是圆弧面， 卡槽 49的槽口则为圆弧形， 卡槽卡在限位槽 中。
还可以设置用于插入卡接头外段的块状后支承座 59和用于引导推线管 1安装于套 扎器枪体 5内的前支承座 63， 两支承座前后设置在枪体 5内壁上， 推线管限位板 16的 卡块 19位于后支承座 59前侧。 推线管 1的后部穿过前支承座 63后伸入后方的支承座 59中。在推线管限位板 16前端部卡块 19的下方斜向延伸一弹力臂 64， 弹力臂 64与推 线管限位板 16可以呈 120度以上的夹角， 在弹力臂 64的前方设置纵向的支撑柱 65， 弹力臂 64的前端抵压在支撑柱 65上， 以提供向上的作用力使推线管限位板 16的卡块 19顶紧在卡接头 41的限位槽 42中， 同时也可使推线管限位板被凸块撬动后的复位。
在推线管释放轮 14的侧面圆周上设有用于标识推线管的标记 66， 标记为数字 "0、
1、 2、 3 "， 标记 "0"表示转轮处于一个原始起点位置， 标记 " 1、 2、 3 "分别表示轮面 上有一个凸块顶起与之对应推线管限位板后端部的位置， 以清楚推线管弹出的情况。 参见图 20~24，显示推线管释放轮 14上的凸块 18尚未顶起推线管限位板 16，此时， 推线管释放轮 14上的标记 "0"表示推线管释放轮 14处于一个原始起点位置， 轮面 17 上没有凸块顶起推线管限位板。 参见图 25、 26， 转动推线管释放轮 14使凸块 18顶起 与之对应的推线管限位板 16， 同时该推线管限位板 16的弹力臂 64抵压在支撑柱 65上 发生形变， 随着推线管释放轮 14继续转动， 撤销了凸块 18对推线管限位板 16施加的 作用力，依靠弹性力臂 64的弹性回复力使推线管限位板 16回复至原位， 而当插入推线 管时， 弹力臂发生形变， 卡接头的限位槽与推线管限位板的卡块相对应时（即推线管安 装到位）， 依靠弹力臂的弹性回复力将推线管限位板的卡块卡紧在限位槽中。
本实施例的使用过程如下： 如图 19所示装配完整的套扎器， 需要弹出推线管进行 套扎时， 取下推线管固定夹， 转动推线管释放轮从标记" 0"的位置到标记 " 1 "的位置， 轮面上的一个凸块顶起与之对应推线管限位板后端部，使该推线管限位板绕其铰接轴转 动，推线管限位板前端部下落，使卡块的槽口从限位槽脱出，从而撤销对推线管的限位， 推线管在处于拉伸状态弹力线的回复力作用下，使伸入枪体内的推线管的后端部从枪体 弹出。 推线管弹出后， 再用手指拨动驱动轮， 由此带动牵引线向后移动， 在牵引力作用 下，沿发射头管壁分布的牵引线与牵引块则向发射头管口移动， 并带动弹力线环套一起 向管口移动， 直至环套从发射头管口脱出， 与此同时将痔疮组织套住。此时推线管组件 (包括推线管、 弹力线、 弹力线头端的环套、 弹力线尾端的卡接头）完全游离。 将游离 的推线管前端向前抵住环套的着力部位，同时将插接于推线管后端管口内的卡接头柱体 内段拔出，藉此向后抽拉牵引线，此两力对抗牵引使得环套的孔径逐渐缩小直至接近于 零， 从而将痔疮组织（或其他目标组织）牢牢扎紧； 打开负压释放开关， 消除负压并从 发射头释放被套扎的组织， 自此便完成了一次套扎操作。 需要下一个推线管弹出时， 依 次转动推线管释放轮至标记 "2、 3 " 的位置即可。
当上述一支枪管组件上的弹力线均使用完后， 还要继续使用弹力线进行套扎操作 时，可将使用完弹力线的枪管组件拆卸下来； 重新将配套装有弹力线的新枪管组件安装 在枪体上， 同时各推线管穿过前支承座伸入枪体内， 与弹力线尾端相连的卡接头的外段 在伸入过程中，下压卡块使弹力臂发生形变， 使卡接头的限位槽与推线管限位板的卡块 相对应槽口卡接， 并依靠弹力臂的弹性回复力将推线管限位板的卡块卡紧在限位槽中， 外段尾端伸入到后支承座中， 这样推线管安装到位。 再将牵引线旋钮套接在转接轴上， 取下推线管固定夹， 即可重新开始进行上述套扎操作。
实施例 3 本实施例 3与实施例 1的主要区别之处在于：推线管采用推线管弹出机构插装在枪 体内，取代实施例 1中推线管经过推线管释放机构安装在枪体内。推线管弹出机构的具 体组成、连接关系及其动作过程（见图 20 31所示）与实施例 2中的推线管弹出机构相 同， 不一一赘述。本实施例的套扎过程和实施例 1类同， 只是释放推线管的操作不同而 已。
另外， 也可将实施例 2中的枪管和枪体可拆卸安装结构组合到实施例 1中， 取代实 施例 1 中的枪管和枪体的一体连接， 组合连接成另一实施方式的套扎器 （图中没有示 出）， 也可以达到本发明的技术效果。
上述各套扎器实施方式的各组成部件也可采用金属或其他材料制作； 分支牵引线至 少为两根，沿发射头管口呈对称性分布以便为弹力线的环套提供均匀拉力， 使得环套能 够顺利地套在目标组织上；牵引线与环套之间的连接还可以通过其它方式来实现； 弹力 线的尾端穿过推线管也可以采用卡块使其尾端卡扣于推线管的后端管口处。
本发明的实施方式不限于此，根据本发明的上述内容， 按照本领域的普通技术知识 和惯用手段，在不脱离本发明上述基本技术思想前提下，本发明的推线管和弹力线采用 1〜3 个或者更多数量， 与之相配合的部件也做相应地增加； 本发明自动弹力线套扎器 的推线管弹出机构各零部件的具体结构均具有其它的实施方式；推线管限位板和推线管 释放轮上的凸块的数量可以根据套扎器的需要来设置；因此本发明还可以做出其它多种 等同形式的修改、 替换或组合， 均落在本发明权利保护范围之内。
