Description

一种肠管焊接装置 技术领域
本发明属于外科医学技术领域，涉及一种基于高频软组织焊接技术，特别涉及一种端端肠管焊接装置。
背景技术
外科手术是肠胃肿瘤的主要治疗方法，而肠管吻合是手术中必不可少的关键步骤。传统的开放式手术通常采用皮钉或丝线缝合的方式进行肠管吻合。然而，这种传统方式容易引发吻合口出血、吻合口瘘等肠管吻合的严重并发症，甚至存在导致患者术后死亡的风险。
随着腹腔镜技术的发展，传统吻合技术已经无法满足现代手术对肠管吻合的要求。最近几十年，电外科技术领域医疗器械迅速发展，电外科相关理论也为消化道缝合器的发展和进步提供了新思路、新方法。
高频软组织焊接技术是20世纪90年代由乌克兰巴顿焊接研究所提出的一种新型无线吻合技术，主要通过感应组织的电阻抗来精确控制高频电流作用于软组织的温度和时间，从而实现对软组织的切割、凝结和焊接效果。相比于传统吻合术，高频软组织焊接技术具有许多优点，包括组织渗血减少、止血效率提高、微创无疤痕、缩短手术时间、减少病人手术风险，从而可以最大限度减少四周组织损伤和坏死。
然而，现有的高频软组织焊接装置或机械式软组织管型吻合器结构复杂、机械设计难度大，而且需要通过在肠管侧壁制造切口来伸入腔进行肠管吻合。这种肠管吻合的方式不但会使患者的肠腔变得狭窄，还会给患者的肠管造成二次损伤，从而加大手术风险并且不利于患者恢复。
因此，为了克服现有技术存在的上述缺陷，亟需一种安全高效的肠管吻合技术，用于简化装置结构、提高止血效果、避免肠腔狭窄，并避免肠管侧壁切口对患者造成的二次伤害，从而降低患者的痛苦并加快患者恢复。

如图1所示，本发明提供的上述肠管焊接装置可以包括两个焊接头10、20。在一些实施例中，焊接头10可以包括主体11和环形电极12。主体11可以为筒状，用于固定一段断肠的外部。环形电极12可以设于主体11的末端，电性连接一高频电源以提供高频电压。在一些实施例中，焊接头20可以包括主体21和环形电极22。主体21可以为筒状，用于固定另一段断肠的外部。环形电极22可以设于主体21的末端，电性接地以配合环形 电极12向断肠待焊接的吻合处提供高频电压。
本领域的技术人员可以理解，上述将环形电极12电性连接到高频电源而将环形电极22电性接地的方案只是本发明提供的一个实施例，主要用于清楚地展示本发明的构思，并提供一种便于公众实施的具体方案，而非用于限制本发明的保护范围。可选地，在另一些实施例中，也可以采用将环形电极22电性连接到高频电源而将环形电极12电性接地的方案，以取得相同的效果。
在一些实施例中，在进行肠管焊接之前，操作者可以先将距离两段断肠的断口5-10cm处夹住以阻止肠管内粪便等物质不断溢出，并对吻合处的肠管内壁黏膜进行清洗和消毒。可以理解的是，5-10cm的距离并非一种限制性的描述。在其他实施例中，也可以采用不影响焊接头10、20固定断肠断端的任意其他合适的距离。之后，操作者可以将焊接头10的主体11环绕于一段断肠的断端外部以固定该断肠，并将该断肠的断口沿环形电极12外翻直至待焊接的吻合处抵住环形电极12。同样地，操作者可以将焊接头20的主体21环绕于另一段断肠的断端外部以固定该断肠，并将该断肠的断口沿环形电极22外翻直至待焊接的吻合处抵住环形电极22。之后，两个焊接头10、20可以相互压紧，以使两个环形电极12、22相互配合以压紧两段外翻断肠的内壁。之后，两个环形电极12、22可以配合地向两段断肠的吻合处提供高频电压，以采用高频软组织焊接技术来对该两段断肠的内壁进行焊接。
采用高频软组织焊接技术来焊接软组织的原理是通过向软组织的两端施加特殊高频电压，使软组织的细胞膜破裂以释放胶原蛋白，并使释放的胶原蛋白变性。同时，高频电压的热效应使分子热运动加速。变性的胶原蛋白在软组织断端的吻合处形成凝固性黏连以封闭该软组织断端。
在一些实施例中，该高频电压的电压幅值可以为30-300V。在一些实施例中，该高频电压的脉冲宽度可以为0.1μs-100μs。在一些实施例中，该高频电压的占空比可以为8:11。在一些实施例中，该高频电压的频率可以为100-800kHz。在一些实施例中，使用该高频电压进行肠管焊接的放电时间可以为1-30s。通过控制电压电流以及作用时间，可以获得较好的焊接效果。所述的高频电源还包含：自动监测元件、控制元件，用于自动根据焊接状态控制焊接电压。焊接电源设计有自动检测和控制元件，能实时监测关键参量(电压、电流、时间等)，从而自动根据焊接状态控制焊接电压，即，最佳焊接强度及焊接时间由焊接电源根据肠壁厚度、直径自动设定。采用这种自动反馈控制技术，达到最佳焊接效果。
本领域的技术人员可以理解，上述实施例涉及的操作者并非一种限制性的描述。在一些实施例中，操作者可以是进行肠管焊接的医护人员。在另一些实施例中，操作者也可以是在进行肠管焊接过程中执行相应操作的机械臂。
请结合参考图1和图2A，图2A示出了根据本发明的一个实施例提供的焊接头的后视图。
如图1所示，在本发明的一个实施例中，焊接头10可以包括主体11和环形电极12。主体11可以用于环绕一段断肠的外部以进行固定。环形电极12可以设于主体11的末端，用于配合另一焊接头20的环形电极22压紧两段外翻断肠的内壁。在一些实施例中，环形电极12还可以电性连接一个高频电源(未绘示)，用于向两段断肠的吻合处提供高频电压。
如图2A所示，在一些实施例中，上述主体11可以包括两个夹持件111-112。该两个夹持件111-112可以活动连接以构成筒状的主体11，用于环绕断肠以固定断肠的外部。相应地，上述环形电极12也可以包括两个子电极121-122。子电极121可以为半环状，设于对应夹持件111的末端。子电极122可以为半环状，设于对应夹持件112的末端。该两个子电极121-122的立面123的结构可以相互匹配，并随两个夹持件111-112的闭合而紧密贴合以构成环形电极12。
可以理解的是，上述半环状是一种非限制性的描述，是指环状的一部分，而非严格地限制为环状的一半。在一些实施例中，子电极121-122可以适应于夹持件111-112的形状及尺寸相同而都为环状的一半。在一些实施例中，适应于夹持件111较大而夹持件112较小，子电极121可以为环状的一大部分而子电极122可以为环状的一小部分。在一些实施例中，适应于夹持件112较大而夹持件111较小，子电极122可以为环状的一大部分而子电极121可以为环状的一小部分。
在一些实施例中，夹持件111-112可以由橡胶、塑料等绝缘材质制成，从而防止患者和操作者触电。夹持件111-112的内壁可以设有导线。该导线的一端可以电性连接子电极121-122，而其另一端可以从夹持件111-112的外壁引出以连接高频电源。通过将导线设于夹持件111-112的内壁，可以防止操作者在肠管焊接过程中误触碰导线，从而避免由此引发的医疗事故。在一些实施例中，夹持件111-112的长度可以为3.0-5.0cm，其厚度可以为2.0-6.0mm。
在一些实施例中，主体11可以为圆筒状，其内径可以为1.5-3.0cm。在一些实施例中，主体11上可以设有一螺纹结构。焊接头10可以通过该螺纹结构可拆卸地安装于一焊接柄。操作者可以根据待焊接断肠的外径，便捷地更换具有适应内径的主体11的焊接头10，从而更好地固定该断肠的外部。可以理解的是，该适应内径可以指一略小于断肠外径的尺寸(例如：小0.1-0.5cm)。通过选用内径略小于断肠外径的主体11，可以向该断肠提供一向内的力，以便于固定该断肠的外部。在一些实施例中，操作者还可以通过该螺纹结构，便捷地拆卸使用过的焊接头10，并对其进行清洗和消毒。
如图2A所示，在一些实施例中，夹持件111-112可以由一旋转件13活动连接。具体来说，两个夹持件111-112可以在旋转件13的限制下旋转打开以供操作者放入断肠，或旋转闭合以构成筒状的主体11来固定该断肠的外部。
在一些实施例中，上述旋转件13可以是一合页。该合页的长度可以与主体11保持一致，从而提升主体11的结构稳定性。该合页可以由不锈钢材料制成。具体来说，该合页可以包括一第一合页片、一第二合页片，以及一合页轴。该第一合页片可以固定于夹持件111上。该第二合页片可以固定于夹持件112上。该第一合页片和该第二合页片分别固定连接该合页轴，可以围绕该合页轴进行旋转。在一些实施例中，操作者可以向外用力以打开两个夹持件111-112，即增大两个夹持件111-112张开的角度，直至主体11完全打开。相应地，操作者也可以向内用力以关闭两个夹持件111-112，即减小两个夹持件111-112张开的角度，直至主体11完全闭合。
如图2B所示，在一些优选的实施例中，夹持件111可以设有一锁扣141。夹持件112可以设有一锁座142。锁扣141可以和锁座142配合作用，向两个夹持件111-112提供一向内的力，从而使两个夹持件111-112紧密闭合以稳定地夹持固定一段断肠的外部。在一 些实施例中，锁扣141和锁座142可以设于两个夹持件111-112的接壤处，以提供更稳定的夹持固定效果。在一些实施例中，锁扣141可以安装于夹持件111的1/2处，锁座142可以安装于夹持件112的1/2处，以提供更稳定的夹持固定效果。在一些实施例中，夹持件111可以设有多个锁扣141，而夹持件112可以设有多个锁座142，以提供更稳定的夹持固定效果。
如图3所示，本实施例提供的上述锁扣141和上述锁座142可以通过螺钉分别固定安装于对应的夹持件111-112。具体来说，锁扣141可以包括一弹簧件31和一锁环32。弹簧件31连接锁环32，用于向锁环32提供一向下的力。当需要使用锁扣141和锁座142来锁定两个夹持件111-112以构成筒状的主体11，可以对弹簧件31施加一向上的力以提起锁环32。之后，可以将锁环32套入锁座142，并撤去该向上的力。锁环32将在弹簧件31提供的向下的力的作用下扣住锁座142，以锁定两个夹持件111-112。在一个优选的实施例中，锁座142的末端可以向上倾斜以提供更稳定的固定效果。
本领域的技术人员可以理解，上述通过锁扣141和锁座142来夹持固定断肠外部的方案只是本发明提供的一个实施例，主要用于清楚地展示本发明的构思，并提供一种便于公众实施的具体方案，而非用于限制本发明的保护范围。
如图4所示，在本发明的另一个实施例中，上述旋转件13可以是一个弹性旋转件40。两个夹持件111-112可以在弹性旋转件40的弹力作用下紧密闭合以构成筒状的主体11。具体来说，该弹性旋转件40的内部可以设有一弹簧。该弹簧的一端固定连接夹持件111，另一端固定连接夹持件112。该弹簧可以分别向两个夹持件111-112提供一向内的弹性力，从而使两个夹持件111-112自动地紧密闭合以夹持固定一段断肠的外部。
在一些实施例中，该弹性旋转件40还可以包括一夹体41。该夹体41分别连接上述弹簧的两端，用于在一捏紧力作用下，向该弹簧提供一向外的力以打开两个夹持件111-112。在一些实施例中，操作者可以向夹体41提供一捏紧力以打开两个夹持件111-112，即增大两个夹持件111-112张开的角度。施加的捏紧力越大，则两个夹持件111-112张开的角度越大，直至主体11完全打开。相应地，操作者也可以撤去该捏紧力以关闭两个夹持件111-112，即减小两个夹持件111-112张开的角度。响应于捏紧力被撤去，两个夹持件111-112将在弹簧提供的向内的弹性力的作用下自动闭合，直至主体11完全闭合。
通过将旋转件13优选为弹性旋转件40，两个夹持件111-112可以响应于操作者撤去捏紧力而自动闭合，从而提升夹持固定断肠外部的效率。更进一步地，通过选用具有合适弹力的弹簧和具有合适柔韧度的主体11的材料，还可以进一步调节主体11对断肠外部的夹持力，从而提供更稳定的固定效果。
本领域的技术人员可以理解，上述通过旋转件13和弹性旋转件40旋转连接的两个夹持件111-112只是本发明提供的一个实施例，主要用于清楚地展示本发明的构思，并提供一种便于公众实施的具体方案，而非用于限制本发明的保护范围。
如图5所示，在本发明的另一个实施例中，两个夹持件51-52可以滑动连接以构成一筒状的主体50，用于环绕一段断肠以固定该断肠的外部。在一些实施例中，主体50可以为圆筒状，其直径为1.5-3.0cm。主体50的长度可以为3.0-5.0cm，厚度可以为2.0-6.0mm。在一些实施例中，夹持件51可以为圆筒的1/3，其末端可以设有一1/3圆环 状的子电极。相应地，夹持件52可以为圆筒的2/3，其末端可以设有一2/3圆环状的子电极。在一些实施例中，操作者可以将夹持件51向左推离夹持件52以打开主体50。相应地，操作者也可以将夹持件51向右推向夹持件52以关闭主体50。当夹持件51与夹持件52完全重合时，主体11完全闭合。同时，两个子电极将相互匹配并紧密贴合，以构成一完整的环形电极。
本领域的技术人员可以理解，上述打开及关闭主体50的方案只是本发明提供的一个实施例，主要用于清楚地展示本发明的构思，并提供一种便于公众实施的具体方案，而非用于限制本发明的保护范围。可选地，在另一些实施例中，操作者也可以将夹持件51向右推离夹持件52以打开主体50，或将夹持件51向左推向夹持件52以关闭主体50。可选地，在另一些实施例中，操作者也可以将夹持件51向上推离夹持件52以打开主体50，或将夹持件51向下推向夹持件52以关闭主体50。
在一些实施例中，夹持件51-52可以通过凸槽和凹槽构成的滑动结构来进行滑动连接。
请进一步参考图6A-6B，图6A示出了根据本发明的一个实施例提供的带凸槽的夹持件的结构示意图。图6B示出了根据本发明的一个实施例提供的带凹槽的夹持件的结构示意图。
如图6A所示，夹持件51的两侧可以包括两个凸槽511-512，其凸出部分高度为0.5-1.5cm。如图6B所示，夹持件52的两侧可以包括两个凹槽521-522，其凹陷部分深度为0.5-1.5cm，并与凸槽511-512的高度相匹配。凸槽511可以与凹槽521配合，而凸槽521可以与凹槽522配合，从而滑动连接两个夹持件51-52以构成筒状的主体50。
在一些优选的实施例中，各凸槽511-512的中部可以设有一螺孔。各凹槽521-522的两个槽壁的中部也可以分别设有一螺孔。凸槽511的螺孔可以与凹槽521的两个螺孔位置相对，从而与一螺钉配合作用以固定两个夹持件51-52的一侧。相应地，凸槽512的螺孔可以与凹槽522的两个螺孔位置相对，从而与另一螺钉配合作用以固定两个夹持件51-52的另一侧。在凸槽511-512与凹槽521-522构成的滑动结构，以及螺孔与螺钉构成的螺纹结构的共同作用下，可以紧密地闭合两个夹持件51-52以固定断肠的外部。
在本发明的一些实施例中，两个焊接头10、20的环形电极12、22可以由铜或镍铬合金制成，其厚度可以为1.0-3.0mm。在一些实施例中，环形电极12、22的宽度可以为2.0-6.0mm，与主体11、21的厚度一致。在一些实施例中，环形电极12、22的内环直径可以为1.5-3.0cm，与主体11、21的内径一致。在一些实施例中，环形电极12、22可以由合适的黏性材料黏结于主体11、21的末端。该黏性材料可以根据主体11、21与环形电极12、22的具体材质来决定。在一些实施例中，环形电极12、22的焊接面可以都为平面，从而相互匹配以压紧两段外翻的断肠。
如图7所示，在一个优选的实施例中，环形电极12、22的焊接面可以设置为凹凸状，其中，环形电极12的焊接面形状应当与环形电极22的焊接面形状相匹配。当两个焊接头10、20相互压紧，环形电极12的焊接面与环形电极22的焊接面将相互贴合以压紧两段外翻的断肠。在一些实施例中，凹凸状的焊接面包括波浪形的焊接面。通过将环形电极12、22的焊接面设置为凹凸状，可以在有限的环形电极宽度中进一步增大肠管的焊接面积，从而提升吻合处的机械强度。
在一些优选的实施例中，焊接头10、20还可以与一卡环80配合使用，从而更好地固定断肠。具体来说，该卡环80的内径可以适应于主体11、21的外径。操作者可以在将断肠的断口沿环形电极12、22外翻直至待焊接的吻合处抵住环形电极12、22后，进一步将具有合适内径的卡环80套在断肠的外翻部外，从而进一步将断肠的外翻部固定于主体11、21的外壁，保持对外翻肠壁组织压力固定，保证电焊接可靠实现。
如图8所示，卡环80可以由两个半圆环81、82构成。两个半圆环81、82之间由活动栓83活动连接。两个半圆环81、82的末端可以设有两个互相匹配的卡扣84，卡扣84结构上设有凹槽。在一些实施例中，操作者可以使劲按压两个半圆环81、82，以使其末端的卡扣84相互咬合。相互咬合的两个半圆环81、82会向断肠的外翻部施加一向内的力，从而将断肠的外翻部固定于主体11、21的外壁。在一些实施例中，操作者可以再次使劲按压相互咬合的两个半圆环81、82，以使其末端的卡扣84解除咬合。
本发明的一些实施例中，焊接装置还可包含：分别连接所述两个焊接头的联动机构，在焊接工作状态下，通过所述的联动机构分别驱动两个焊接头对接压紧，并保持同轴对中，以提高焊接效果。
请继续参考图1，在本发明提供的上述肠管焊接装置中，焊接头10还可以固定连接一焊接柄60，而焊接头20还可以固定连接一焊接柄70。两个焊接柄60、70可以通过一铰腰90旋转连接，用于将两个焊接柄60、70的末端受到的力传递到两个焊接头10、20以压紧两段断肠。在一些实施例中，铰腰90的中央可以由一螺钉固定，以便于焊接柄60和焊接柄70绕铰腰90旋转。所述的焊接装置呈现‘钳’状，用于断肠的焊接吻合，而非用于切割或凝血。在一些优选的实施例中，铰腰90可以由非导电材料制成，可采用聚四氟乙烯等高强度绝缘体，用于保证两个焊接柄60、70电压隔离以防止电源短路。
在一些实施例中，操作者可以根据断肠的组织大小、尺寸和肠管厚度来确定焊接该断肠所需的高频电压的电参数。该电参数包括但不限于高频电压的幅值、频率、脉冲宽度、占空比和放电时间。肠壁厚度和直径都可表现为负载阻抗。在一些优选的实施例中，该高频电压的幅值可以正相关于该断肠的组织大小、尺寸和肠管厚度。更优地，两个焊接头10、20压紧断肠的力可以正相关于其环形电极12、22向断肠提供的高频电压的幅值。
如图1所示，在一些实施例中，焊接柄60的末端可以设有一指环孔61，而焊接柄70的末端也可以设有一指环孔71。指环孔61、71可以为适于手指抓握的不标准椭圆形，其孔径可以为1.5-3.0cm。操作者可以将其拇指和食指伸入两个指环孔61、71内，以压紧或分离位于焊接柄60、70另一端的两个焊接头10、20。
在一些实施例中，焊接柄60、70可以由钛合金或者其他密度低、硬度大、金属稳定性较强的金属材料制成，其长度可以为8.0-15.0cm。铰腰90可以位于焊接柄60、70的前部，即焊接头10、20所在的前端与焊接柄60、70的中点之间的区域，从而通过力臂结构向焊接头10、20提供成倍于操作者握力的压紧力。铰腰90到焊接柄60、70的前端的具体距离可以根据焊接断肠所需的目标压紧力而进行具体设计。
如图1所示，在一些优选的实施例中，焊接柄60的后部，即指环孔61所在的末端与焊接柄60的中点之间的区域，还可以设有一限位卡条62。限位卡条62可以包括至少一个卡槽63。相应地，焊接柄70的后部，即指环孔71所在的末端与焊接柄70的中点之间的区域，也可以设有一限位卡条72。限位卡条72也可以包括至少一个卡槽73。限位卡 条62和限位卡条72可以相向设置，以便于两者的卡槽63、73相互咬合。在一些实施例中，操作者可以通过指环孔61、71用力压紧两个焊接柄60、70的末端，以使限位卡条62的卡槽63与限位卡条72的卡槽73相互咬合。咬合的卡槽63、73相互固定，并向焊接柄60、70的末端提供一恒定的向内的力，以维持焊接头10、20压紧断肠的力。
在一个更优的实施例中，卡槽63在限位卡条62的位置，以及卡槽73在限位卡条72的位置可以根据焊接柄60、70的硬度来设计。具体来说，两个限位卡条62、72的卡槽63、73可以相互咬合，从而向焊接柄60、70的末端提供一恒定的向内的力，以使两个焊接柄60、70发生形变。该形变可以通过铰腰90的力臂结构，在两个焊接头10、20处产生一向内的压紧力。压紧力可通过手柄的结构调节并固定。设计者可以对对应于高频电压的幅值的目标压紧力进行力臂结构的换算，以获得对应的目标形变力。之后，设计者可以根据该目标形变力和焊接柄60、70的硬度求出对应的目标形变量，从而确定卡槽63在限位卡条62的位置，以及卡槽73在限位卡条72的位置。
本领域的技术人员可以理解，上述每个限位卡条62、72只包括一个卡槽63、73的方案只是本发明提供的一个实施例，主要用于清楚地展示本发明的构思，并提供一种便于公众实施的具体方案，而非用于限制本发明的保护范围。可选地，在另一些实施例中，每个限位卡条62、72也可以包括多个卡槽。优选地，每个卡槽在对应限位卡条的位置可以对应一个高频电压的幅值。
在一些实施例中，限位卡条62的内侧，即与焊接柄60相连的一侧，还可以设有一虚卡槽64。相应地，限位卡条72的内侧，即与焊接柄70相连的一侧，也可以设有一虚卡槽74。在一些实施例中，操作者可以向相互咬合焊接柄60、70施加一向内的力以进一步压紧两个限位卡条62、72。响应于两个限位卡条62、72的虚卡槽64、74对接，两个限位卡条62、72可以解除咬合而自由地打开。此时，焊接头10、20向断肠提供的压紧力被撤销。
如图1所示，在一些实施例中，焊接柄60还可以包括一导线接口65。该导线接口65可以电性连接一高频电源，并通过一导线电性连接焊接头10的环形电极12以提供外部的高频电压。相应地，焊接柄70还可以包括一导线接口75。该导线接口75可以电性接地，并通过一导线电性连接焊接头20的环形电极22以配合环形电极12向断肠待焊接的吻合处提供外部的高频电压。在一些实施例中，导线接口65可以设于限位卡条62和指环孔61之间。导线接口75可以设于限位卡条72和指环孔71之间。在一些实施例中，导线接口65、75可以为铜制的圆柱状接口，其长度可以为1.0-2.0cm。
在一些优选的实施例中，焊接柄60、70可以为中空结构。电性连接导线接口65的导线可以通过焊接柄60的中空结构(如，可设置导线通道)，电性连接焊接头10的环形电极12以提供外部的高频电压。电性连接导线接口75的导线可以通过焊接柄70的中空结构，电性接地以配合环形电极12向断肠待焊接的吻合处提供外部的高频电压。在一些实施例中，两个导线可以经过铰腰90内部的中空结构分别连接对应的焊接头10、20。通过将导线设置于焊接柄60、70的中空结构，可以简化焊接装置的结构，防止操作者在肠管焊接过程中误触碰导线，从而避免由此引发的医疗事故。
在一些优选的实施例中，还设置有环形切削组件15，如图9、图10所示，该环形切削组件15作为一种辅助性工具，在焊接结束后使用。环形切削组件15由刀体1501，刀 片1502，刀柄1503，刀腰1504，指环孔1505，卡条1506等部件构成。刀体1501的内径和焊接圆筒的外径相等或者略大1.0-2.0mm，长度为8.0-14.0cm。每个环形切削组件15包含上下两个刀体1501，可根据需要开合，上下两个刀体分开时是两个半圆环，闭合时形成一个圆筒。刀体1501内壁均匀分布有15-30个刀片1502，刀片长度和刀体长度相等，刀片和刀体切线垂直，刀片尖端锋利。每个刀体分别和一个刀柄1503相连，刀柄1503长度为8.0-14.0cm。两个刀柄1503在刀腰1504处相交，每个刀柄末端有两个指环孔1505，每个指环孔1505能容下大拇指和食指。两个指环孔朝内的方向分别设置一个卡条1506，一个卡槽，相对压指环孔，使卡槽结合起来，两个刀体闭合，形成内切力。
根据本发明的另一方面，本文还提供了一种基于高频软组织焊接技术的肠管焊接方法。
如图11所示，本发明提供的上述肠管焊接方法，可以包括步骤：
901：以两个焊接头分别固定一段断肠的外部；
902：将两段断肠的断口沿对应焊接头的环形电极外翻，所述环形电极设于所述焊接头的主体的末端；
903：以两个所述的环形电极压紧两段外翻的断肠；以及
904：以两个环形电极向断肠的吻合处提供高频电压，进行端端肠管焊接；
905：将打开的上下两个刀体套置在所述的焊接头上，闭合刀体，切掉外翻在焊接头外壁的多余断肠。
可以理解的是，本发明提供的上述肠管焊接方法可以依托于上述任意一个实施例所提供的肠管焊接装置来实施。在一些非限制性的实施例中，该方法可以由上述任意一个实施例中涉及的操作者来实施。该操作者包括但不限于进行肠管焊接的医护人员，以及在进行肠管焊接过程中执行相应操作的机械臂。因此，本发明提供的上述肠管焊接方法可以包括对应于上述任意一个实施例所提供的肠管焊接装置的技术特征，并可以取得对应的技术效果。
尤其是在一些非限制性的实施例中，固定断肠外部的步骤可以进一步包括打开一焊接头的两个夹持件以放入一段断肠的步骤，以及闭合两个夹持件以构成筒状的焊接头的主体的步骤。该主体可以环绕该断肠以固定该断肠的外部。
在一些非限制性的实施例中，压紧断肠的步骤可以进一步包括根据断肠的尺寸和肠管厚度确定高频电压的幅值的步骤，以及向环形电极提供正相关于该幅值的力以压紧断肠的步骤。
在一些非限制性的实施例中，上述焊接方法还可以包括以一卡环将断肠的外翻部固定于焊接头的主体的外壁的步骤。
本发明提供的装置特别适用于端端肠管焊接。本文所述的“端端肠管焊接”区别于侧向肠管焊接，是指完全断开的两段肠管的两端吻合焊接。
尽管为使解释简单化将上述方法图示并描述为一系列动作，但是应理解并领会，这些方法不受动作的次序所限，因为根据一个或多个实施例，一些动作可按不同次序发生和/或与来自本文中图示和描述或本文中未图示和描述但本领域技术人员可以理解的其他动作并发地发生。
