Description
技术领域
本发明涉及医疗器械技术领域，具体地说，是一种测量组织厚度的智能器械。
背景技术
吻合器是一种被广泛应用于外科手术当中的医疗器械，它将吻合口两端的组织拉合在一起，提供力学愈合，为后期的组织愈合创造条件。相比于传统的手工吻合，吻合器具有以下优势：小血管可从吻合钉空隙中通过而不影响缝合部位及其远端的血液供应；缝钉材质为金属钛或钽，与手工缝线相比，组织反应小；吻合钉排列整齐，间距相等，保证了组织的良好愈合；机械吻合将开放式缝合变为密闭式缝合，减少生物腔道重建过程中造成的污染。吻合器的使用需要遵循一定的规范，才能够达到预期目标。其中，很重要的一点就是吻合钉仓的选择，不同颜色的吻合钉仓内置了不同高度的吻合钉，高度分辨率达到0.1mm，适用于不同厚度的组织。吻合器生产厂商在吻合器的使用说明上，仅仅告诉使用者，要根据组织厚度选择合适的吻合钉。这里存在的问题有：首先，医生在手术环境下用肉眼分辨0.1mm数量级的差别是一件不太可能完成的任务；其次，即使医生能够分辨这个差别，但由于组织具有一定的弹性，如何在手术时界定它的厚度？为此，需要一种医疗器械装置，能够为医生提供客观的组织厚度数据，以辅助医生选择正确的吻合钉、顺利完成吻合手术。
再者，医生在使用吻合器时，需要根据肉眼观察，主观判断组织厚度，选择相应的吻合钉仓；这个过程缺乏客观依据，容易造成吻合钉仓选择不当：当钉仓选择偏高时，容易造成吻合口出血；当钉仓选择偏矮时，容易造成周围组织被压烂，影响吻合口愈合，引发吻合口瘘。
中国专利文献CN201410510194.X，申请日2014年09月29日，专利名称为吻合器辅助装置、具有该辅助装置的吻合器和手术器械，公开了一种吻合器辅助装置，包括辅助装置本体、设置在所述辅助装置本体内部且以其近端与吻合器本体连接的连接器、与所述连接器远端连接的推动装置、与所述推动装置远端连接且可闭合的活动钳口与固定钳口、设置在所述活动钳口与所述固定钳口之间的承压装置，且所述承压装置由一个或多个承压单元组成。用于在吻合前判断所需要的吻合钉钉高，从而选择正确的吻合钉仓，该装置的实施方式是，在预先设定的承压临界值范围内，对组织进行预压缩，使组织厚度分布均匀、便于缝合，同时通过闭合间隙的大小判断所需要的吻合钉钉高,通过一个推动装置指示吻合钉仓的选择结果；承压装置含有承压弹簧，可以起到缓冲作用，防止组织被过度压榨；当组织承受的压力超过临界值时，会触发锁定装置，使操作者无法继续击发，从而保护组织。其实施方式是在对组织实施预压榨的过程中进行测量，根据测量结果选择吻合钉仓，再使用吻合器在同一位置进行吻合；但并未指明对组织所施加的压强大小的具体数值，从其描述可知，预压榨过程可以使组织厚度分布更加均匀，这个过程伴随着细胞外液排出体外，因此可以想象，压强值不会太小，组织在这个过程中已经经历了类似于吻合器压榨的效果，如果测量时间长，有可能还会引起局部缺血；测量完成后，当医生再使用吻合器进行吻合时，需要找到与测量时完全一致的部位，由于吻合对象的柔性特点和人体内部的复杂环境，这个目标是很难达到的，而如果不能够完全一致，就意味着在吻合口以外的组织位置已经受到了额外的损伤，这对于病人的术后恢复是极为不利的。该出发点是在对组织实施和吻合器相当的压榨之后测量的组织厚度是最准确的，但是组织厚度测量是有一个优化的压强范围的，当对组织实施的压强在这个范围以内时，可以使柔软的组织被固定好、同时不会产生破坏组织的结构性变化，这个压强范围是被工业界所认可的标准。因此，对组织厚度的测量应该遵循这个标准，而不需要追求和吻合器相当的压榨效果。
中国专利文献CN200810086947.3，申请日2008年03月28日，专利名称为腹腔镜组织厚度和夹钳载荷测量装置，公开了一种腹腔镜组织厚度和夹钳载荷测量装置。一种实施方式是所述测量装置可与用于切割和缝合组织的内镜切割器一起使用，允许医生精确和重复地测量组织厚度，使医生能够选择正确的吻合钉仓来执行切割；另一种实施方式包括一种外科装置，其具有一对对置的钳口，用于简单地操作和抓持组织、其它外科器械等。在第一种实施方式中，测量组织厚度的方法是：使用一个应变仪测量组织所承受的压力，当达到一定值时，比如8克，则停止对组织继续施加压力；同时使用另一个应变仪测量器械在夹持组织过程中钉砧所产生的位移，来表达组织厚度，该位移通过结构设计转化为对应变片的压力；组织越薄，位移越大，应变片承受的压力则越大，产生的输出变化也就越大。根据结构描述，测量厚度的应变片被安置在远离测量组织载荷的应变片的近端，两者相距很远，组织的厚度与压强测量实际上不在同一位置；同时根据杠杆远离，器械钉砧近端的位移小于远端位移，因此，该方法实际上是把位移进行缩小后再测量，降低了分辨率；最后，应变片本身的输出线性度和分辨率都较低，因此更适合做定性测量，而非定量测量，并未阐明该种实施方式中组织厚度测量的分辨率。第二种实施方式主要通过机械结构的设计，达到在特定压强下测量组织厚度的目的，压强设计通过预置弹簧或者应变仪来实现，组织厚度测量则通过结构设计直接将测量杆的位移转化为组织厚度，并通过读数盘进行显示，受其构造原理所限，厚度测量分辨率只能够达到1mm，不能够为医生提供足够的数据精度支持。
中国专利文献CN201080058429.6，申请日2010年12月06日，公开了一种分析组织的厚度的外科切割器械，包括：组织夹持端部执行器，所述组织夹持端部执行器包括：可动工作部；组织的厚度模块，所述组织的厚度模块感测夹持在所述端部执行器中的组织的厚度；和控制电路，所述控制电路与所述组织的厚度模块通信，其中，当夹持在所述端部执行器中的组织的厚度不在指定的厚度范围内时，所述控制电路防止所述可动工作部的致动。其测量原理是：当器械夹紧组织后，钉砧和吻合钉仓之间的距离和组织厚度相关；在钉砧远端安置了一块磁体，而在钉仓远端相应的安置了感应磁场强度变化的霍尔传感器；传感器感应磁体的远近，从而判断组织厚度。主要针对已被吻合器压榨后的组织的厚度测量，当组织厚度与钉仓不符时，需要放开已夹持的组织，更换钉仓，然后重新再对组织进行吻合。另外，组织厚度测量的前提是已对组织实施压榨，损伤已经造成，特别是针对偏厚的组织时，容易造成缺血。当第二次实施吻合时，很难保证与上次处于同一位置，这样就造成了额外的组织损伤。
综上所述，亟需一种一定压强下准确测量组织厚度,允许医生在不损伤组织的前提下，精确和重复地测量组织厚度，为其选择吻合钉仓提供客观数据支持，辅助其作出正确选择，提高吻合手术的成功率的测量组织厚度的智能器械。而关于这种智能器械目前还未见报道。

实施例1
请参照图1，图1是本发明的一种测量组织厚度的智能器械结构示意图。一种测量组织厚度的智能器械，所述智能器械包括智能纽扣电池式智能测厚夹1，钉砧2、直线型切割吻合器3、外部遥控装置3；所述纽扣式智能测厚夹与钉砧2形成钳口21；所述钉砧2为不锈钢材料制造而成；所述的外部遥控装置3包括手机、计算机、以及平板电脑。
请参照图2，图2是纽扣电池式智能测厚夹下表面结构示意图。所述纽扣电池式智能测厚夹1近端为直线型，远端为圆弧形，且圆弧形的远端形成一个倾斜面。

请参照图6，图6是纽扣电池式智能测厚夹电路结构框图。当开始进行测量时，通过操作直线型切割吻合器3使钳口21闭合，钳口21施加在组织22上的压力通过按压键13及压力传感器19直接传送到组织压强测量模块154上；当控制模块156检测到组织22受到的压强达到预设值并保持一段时间以后，将驱动组织厚度测量模块155测量组织22厚度，其具体原理是，组织厚度测量模块155会发出交变电磁场，在不锈钢钉砧2内产生涡流，反过来抵消电磁场变化，等效为组织厚度测量模块155内的谐振频率或者电感的变化，通过测量该变化可以得到钉砧2与纽扣电池式智能测厚夹1之间距离的精确变化，进而得到组织22的厚度。组织22厚度测量结果将直接通过显示模块153显示，或者通过无线传输模块157传送到外部的遥控装置上进行显示；组织22压强的实时测量结果也可以通过无线传输方式传送到外部的遥控装置上进行显示。纽扣电池式智能测厚夹1检测组织22厚度时使用的压强和保持时间可以预设于控制模块156内，也可以通过外部遥控装置3进行现场设定。
请参照图7，图7是纽扣电池式智能测厚夹的控制模块流程图。控制模块156执行对组织22测量压强的步骤，可显示或无线传输显示压强，如果控制模块156测量的压强超过警戒值，则执行步骤报警器响，并调整压强反馈到控制模块156测量压强的步骤中；如果控制器模块测量的压强值没有超过是警戒值，则执行步骤压强是否等于预设值；如果压强与预设值不匹配，则执行调整压强反馈到控制模块156测量压强的步骤中；如果压强与预设值匹配，则继续进行是否保持预设时间的步骤，如果与预设时间不匹配，执行调整压强反馈到控制模块156测量压强的步骤中，如果与预设时间匹配，则进行测量厚度的步骤并显示或无线传输显示厚度。

请参照图18，图18是控制模块与辅控模块电路结构框图。自动测厚器械7内部通过控制板67上电机驱动模块671，驱动上钳口21向下闭合或者向上张开，同时辅控模块68和外接电源式智能测厚夹5内部的控制模块156进行通讯。外接电源式智能测厚夹5将检测到的组织22压强实时传送给辅控模块68，辅控模块68根据实时压强值，驱动电机驱动模块671对上钳口21的运动进行控制；当达到预设压强值时，辅控模块68将继续驱动电动模块对上钳口21进行微调，保持组织22承受的压强值在预设值附近进行小范围波动，并保持到预定的时间为止，之后外接电源式智能测厚夹5将进行组织22厚度的测量，并将测量结果传递给自动测厚器械7的辅控模块68，辅控模块68在人机交互装置65上显示实时测量的压强值和厚度测量结果。
请参照图19，图19是控制模块流程框图。控制模块156执行测量的步骤，然后执行向辅控模块68传输压强数据的步骤，如果没有接收到测量厚度的命令，则返回执行测量压强的步骤；如果接收到测量厚度的命令，则执行测量厚度的步骤，然后执行向辅控模块68传输厚度数据的步骤。
请参照图20，图20是辅控模块流程框图。辅控模块68首先接收控制模块156传送压强的数据，执行压强是否超过警戒值的步骤，如果压强超过警戒值，则启动报警音响的步骤以及驱动电机驱动模块671调整压强的步骤，并把数据反馈至辅控模块68；如果压强没有超过警戒值，则执行压强是否等于预设值的步骤；如果压强不等于预设值，则执行驱动电机驱动模块671的步骤，如果压强等于预设值，则执行是否保持预设时间的步骤，其中，如果不保持预设时间，则执行驱动电动模块的步骤，并把把数据反馈至辅控模块68；如果保持预设的时间，则执行发送厚度测量的步骤，接收控制模块156传送厚度数据的步骤，以及显示厚度的步骤。
本发明的一种测量组织厚度的智能器械，定量测量组织厚度，组织22厚度测量精确，便于选择相应的吻合钉仓，提高吻合手术的成功率；一定压强下2g/mm2-90g/mm2对组织22厚度进行测量，压强设置范围广；当使用小压强范围2g/mm2-90g/mm2进行组织22厚度测量时，柔软的组织22得到很好地固定，同时不会对组织22造成损伤；当使用大压强范围2g/mm2-90g/mm2进行组织22厚度测量时，可以模拟吻合器对组织22施压；涡流传感器18和压力传感器19位置基本一致，可以保证测量对象的一致性，降低了对真实厚度估计造成的误差；通过涡流传感器18对组织22厚度进行测量，通过感知钉砧2的移动进行厚度测量，可以和现有的吻合器相结合使用，降低了使用成本；涡流传感器18可以使组织22厚度精确到0.1mm,与吻合钉仓的高度分辨率一致，能够满足根据组织22厚度选择吻合钉仓的技术要求；纽扣电池式智能测厚夹1的配合直线型切割吻合器3使用，代替吻合钉夹装配在吻合器上，夹持在纽扣电池式智能测厚夹1上的组织22达到某一固定压强范围并保持一段时间时，纽扣电池式智能测厚夹1将测量其厚度并显示或无线传输到外部遥控装置3；外接电源式智能测厚夹5可以和手动测厚器械6或者自动测厚器械7结合使用，参数设置和测量结果显示全部集成与手动测厚器械6或者自动测厚器械7的主体上，方便医生操作和观察。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员，在不脱离本发明方法的前提下，还可以做出若干改进和补充，这些改进和补充也应视为本发明的保护范围。
