具体实施方式
现在将参考附图更全面地描述示例实施方式。然而,示例实施方式能够以多种 形式实施,且不应被理解为限于在此阐述的实施方式;相反,提供这些实施方式使得本发明将全面和完整,并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构,因而将省略对它们的重复描述。
本发明提供了一种吻合口保护装置,所述装置包括保护套、第一固定组件、第二固定组件和供电组件。所述保护套位于管状组织内部与吻合口相对应的位置,保护套对吻合口的内表面起到保护作用,在引导管状组织内容物通过的过程中不会污染吻合口。所述第一固定组件设置于所述管状组织的外壁,所述第一固定组件包括电磁发生部件,所述电磁发生部件在输入供电电流时可以产生磁性,以使得所述电磁发生部件通电后产生磁性。所述供电组件与所述电磁发生部件电连接,用于对所述电磁发生部件供电。所述第二固定组件设置于所述保护套的内表面,所述第二固定组件本身具有磁性或者可被磁性吸引,与所述电磁发生部件通过磁性吸附而相对固定,因此通过第一固定组件和第二固定组件之间的磁性吸附,将保护套固定在需要的位置。
由于该吻合口保护装置中只有第一固定组件和第二固定组件之间的磁性吸附位置是相对固定的,不会阻碍管状组织的正常蠕动,并且给管状组织提供周向伸缩的空间,保证吻合口附近正常的供血。第一固定组件包括可以通电而具有磁性的电磁发生部件,通过控制供电的通断来灵活控制电磁发生部件中的磁性有无,并且可以通过控制供电电流的大小和电磁发生部件的绕组匝数来灵活控制电磁发生部件中的磁性大小。
下面结合附图详细介绍本发明各个具体实施例的吻合口保护装置的结构,可以理解的是,各个具体实施例不作为本发明的保护范围的限制。在各个实施例中,以肠道组织为例进行说明。可理解的是,在其他实施方式中,所述管状组织不限于肠 道组织,也可以为人体内的其他管状组织,例如消化道中其他位置的管状组织等,均属于本发明的保护范围之内。
如图1~8所示,为本发明第一实施例的吻合口保护装置应用于肠道组织9的结构示意图。如图1~4所示,所述吻合口保护装置包括:保护套1,位于肠道组织9内部与吻合口相对应的位置,对吻合口的内表面起到保护作用,在引导肠道内容物通过的过程中不会污染吻合口;第一固定组件,设置于所述肠道组织9的外壁,所述第一固定组件包括电磁发生部件;供电组件,与所述电磁发生部件电连接,用于对所述电磁发生部件供电,以使得所述电磁发生部件通电后产生磁性;以及第二固定组件,设置于所述保护套1的内表面,所述第二固定组件与所述第一固定组件的电磁发生部件通过磁性吸附而相对固定。
该装置中只有第一固定组件和第二固定组件之间的磁性吸附位置是相对固定的,不会阻碍管状组织的正常蠕动,并且给管状组织提供周向伸缩的空间,保证吻合口附近正常的供血。第一固定组件中的电磁发生部件可在通过供电组件供电时产生磁性。因此可以通过控制供电的通断来灵活控制电磁发生部件中的磁性有无,并且可以通过控制供电电流的大小来灵活控制电磁发生部件中的磁性大小。
在该实施例中,所述电磁发生部件为电磁铁2。电磁铁是通电产生电磁的一种结构,在铁芯的外部缠绕与其功率相匹配的导电绕组,在向导电绕组中通电时,这种通有电流的绕组像磁铁一样具有磁性。因此,在该实施例中,也可以通过控制所述电磁铁2中的线圈匝数来调整电磁铁2中通入电流后产生的磁性大小。在其他可替代的实施方式中,所述电磁发生部件也可以采用其他结构,例如电磁线圈等,均属于本发明的保护范围之内。
如图1~4所示,在该实施例中,所述第一固定组件包括间隔设置的多个电磁 铁2,所述多个电磁铁2沿所述肠道组织9的周向依次排布,以对所述保护套1形成一个均匀、稳定的固定。所述第二固定组件包括与所述电磁铁2一一对应的内部固定块3。所述内部固定块3可以采用自身不带磁性但可以被磁铁吸引的材料,例如铁、镍、钴等亲磁的金属及其合金等。或者,所述内部固定块3可以采用自身带有磁性的磁性材料,如磁铁等。在该实施例中,多个所述电磁铁2彼此间隔设置,多个所述内部固定块3彼此间隔设置。电磁铁2和内部固定块3的数量也可以根据需要选择设置,并且电磁铁2和内部固定块3之间可以形成一一对应的关系,一对多的关系,或者多对一的关系等等,均属于本发明的保护范围之内。在其他可替代的实施方式中,电磁铁2也可以设置为1个和/或内部固定块3也可以设置为1个。
如图2所示,所述保护套1为管状的保护套管,可以对吻合口形成周向的保护。所述保护套1可以为一个壁厚很薄的具有柔性的薄膜套管,例如橡胶薄膜套管、硅胶薄膜套管等,但本发明不限于此。在其他可替代的实施方式中,所述保护套1也可以采用其他形状,全部或部分覆盖所述吻合口的内壁,均属于本发明的保护范围之内。
所述固定组件优选设置于所述吻合口的上游一侧,用来固定保护套1,使得保护套1不至于向吻合口的下游一侧运动而失去对吻合口的保护。在本发明中,吻合口的上游指的是以肠道内容物沿肠道移动的方向为参照,肠道内容物沿肠道从吻合口的上游一侧向吻合口的下游一侧移动。在该吻合口保护装置应用于肠道低位时,保护套1引导排泄物沿肠道排出,从吻合口上游一侧移动至吻合口下游一侧。
如图2和图3所示,所述保护套1位于所述吻合口的上游的一端设置有支撑部11,所述支撑部11在所述保护套1的径向方向可伸缩。所述支撑部11在径向方向收缩时,所述保护套1可以整体放入肠道组织9内部或从肠道组织9内部取出,在 所述保护套1放置到位之后,所述支撑部11在径向方向扩张,以形成对保护套1的支撑,保持保护套1的位置。支撑部11可以采用可充气放气的环形气囊,在充气时处于径向扩张状态,在放气时处于径向收缩状态。所述支撑部11也可以采用其他的具有径向可伸缩的弹簧或径向可运动的滑块结构,能够实现支撑部11的外径增大或缩小即可。所述第一固定组件和第二固定组件设置于所述吻合口与所述支撑部11之间,通过与支撑部11的配合可以更好地将保护套1保持在吻合口位置。
如图1所示,在该实施例中,所述供电组件包括供电线束6,所述供电线束6环绕所述肠道组织9的外壁,且分别与各个所述电磁铁2电连接。进一步地,所述供电组件还包括输入电源7。所述供电线束6可以与输入电源7电连接,输入电源7通过供电线束6向电磁铁2的导电绕组供电,使得电磁铁2产生磁性。电磁铁2可以使用在通电时具有磁性,在断电时快速消磁的结构。在需要将电磁铁2固定于肠道组织9的外壁时,通过输入电源7在供电线束6中通电,从而使得电磁铁2与内部固定块3磁性吸附。在使用过程中,供电线束6持续为电磁铁2供电。内部固定块3为本身具有磁性的磁性块时,电磁铁2与内部固定块3的磁性相反。需要将电磁铁2从肠道组织9的外壁移除时,可以切断输入电源7对供电线束6的供电,使得电磁铁2失去磁性。通过控制供电线束6中供电电流的大小,也可以控制电磁铁2的磁性强度大小。在其他可替代的实施方式中,所述电磁铁2也可以采用在断电后缓慢消磁的结构,即在供电具有磁性之后,再断电时,能够保持一段时间磁性。
如图4所示,所述供电线束6包括多个线束承载部61和多个线束连接部62,所述线束承载部61为环状的中空结构,环绕于所述电磁铁2的外部,所述线束连接部62连接于两个相邻的所述线束承载部61之间,所述线束承载部61和所述线束连接部62组合形成环绕所述肠道组织9的外壁的环状结构。如图4所示,所述 电磁铁2的侧面设置有沿周向的第一安装槽22,所述供电线束6的线束承载部61嵌设于所述第一安装槽22中,从而保证所述电磁铁2与所述供电线束6之间稳定的连接。在另一可替代的实施方式中,也可以是所述供电线束6的线束承载部61的内侧面设置有沿周向的第一安装槽,所述电磁铁2嵌设于所述第一安装槽中。为了更方便地将电磁铁2安装于供电线束6和从供电线束6中移除,所述电磁铁2与所述安装孔的内壁相贴的各个侧壁具有圆角21结构。
在该实施例中,所述供电线束6为弹性线束6,并且至少所述线束连接部62是具有弹性的,从而可以随肠道的蠕动发生弹性形变,而不会给肠道施加限制压力,给肠道提供了可伸缩的运动空间。在所述线束承载部61和所述线束连接部62都是弹性的时候,所述线束连接部62的弹性优选大于所述线束承载部61的弹性,线束承载部61可以与电磁铁2形成更稳定的连接,线束连接部62的弹性变形力更好,可以提供更好的周向伸缩空间。
如图3-4所示,所述供电线束6还包括延伸部63,所述延伸部63的一端与所述线束连接部62相连接,所述延伸部63的另一端延伸出体外,所述延伸部63可以与输入电源电连接。
在该实施例中,为了方便供电线束6在肠道组织9处的安装和移除,所述供电线束6包括第一连接结构。所述第一连接结构是设置于所述供电线束6的两个端部使其可拆卸连接的结构。具体来说,所述供电线束6是一条状线束,其具有两个端部,此两个端部设置有可拆卸的第一连接结构。例如,该第一连接结构包括设置于所述供电线束6的一个端部的凹槽和另一个端部的凸起,凸起可以嵌入在凹槽中,实现所述供电线束6的两个端部的连接,两个端部连接后,所述供电线束6形成一个封闭的环形,将凸起从凹槽中取出,所述第一连接结构断开连接,所述供电线束 6恢复到条状线束。在其他可替代的实施方式中,所述第一连接结构也可以为卡扣结构、螺纹连接结构、粘扣连接结构等。如图6所示,在所述供电线束6安装于肠道组织9处时,所述供电线束6可在所述第一连接结构处连接而环绕所述肠道组织9的外壁,例如形成闭合的环状结构。所述供电线束6的环状结构也可以在连接端点64处断开,而使得所述供电线束6可以成为一个不封闭的环状或条状结构,从而可以从肠道组织9的外壁处脱离。所述供电线束6的连接端点64处的连接可以是通过卡扣、挂钩、粘接、附加固定件等方式,均属于本发明的保护范围之内。供电线束6可以有两种应用方式:一种方式是供电线束6初始状态是一个封闭的环,在需要从肠道组织9中移除时,将其第一连接结构处断开而脱离所述肠道组织9;另一种方式是供电线束6初始状态是一个不封闭的结构,安装在肠道组织9的外部之后,在连接结构处将其封闭成一个环。
如图7所示,所述线束承载部61的宽度w11可以大于所述线束连接部62的宽度w13。由此,所述线束承载部61可以承载宽度较宽的电磁铁2,以实现电磁铁2对保护套1更好的固定作用,并且线束连接部62的宽度较小,可以提高线束连接部62的弹性变形能力,对肠道组织9的蠕动影响大大降低。进一步地,所述线束承载部61的环形壁的宽度w12可以大于所述线束连接部62的宽度w13,提高所述线束承载部61与电磁铁2的连接稳定性。如图8所示,所述线束承载部61的厚度t11可以与所述线束连接部62的厚度t12基本相等。在另一可替代的实施方式中,所述线束承载部61的厚度t11也可以大于所述线束连接部62的厚度t12,以承载较厚的电磁铁2,并且进一步提高线束连接部62的弹性变形能力,可以提供更好的周向伸缩空间。此处厚度方向即相当于形成环状结构后的供电线束6的径向方向(对应于保护套1的径向方向)。
如图3和图4所示,所述电磁铁2与所述肠道组织9相对的表面为弧形表面,该弧形表面的形状与肠道组织9的外壁基本相适应,以实现电磁铁2与肠道组织9的外壁的更好贴合。所述内部固定块3与所述保护套1相对的表面为弧形表面,该弧形表面的形状与保护套1的内表面基本相适应,以实现内部固定块3与保护套1的内表面的更好贴合。
进一步地,在另一种可替代的实施方式中,所述电磁铁2和/或内部固定块3的表面也可以是波浪形的。具体地,所述电磁铁2朝向所述肠道组织9的表面为沿所述肠道组织9的长度方向(如图3中S方向)有高低起伏的波浪形表面,可以更好地适应于肠道组织9的外壁,增大电磁铁2与肠道组织9的接触面积,提高电磁铁2与肠道组织9的外壁的配合程度。所述内部固定块3朝向所述保护套1的表面为沿所述肠道组织9的长度方向(如图3中S方向)有高低起伏的波浪形表面,增大内部固定块3与保护套1的接触面积,可以提高内部固定块3与保护套1的内壁的配合程度。
在该实施例中,所述第一固定组件还包括环绕所述肠道组织9的外壁的第一连接件4,所述第一连接件4包括承载所述电磁铁2的第一承载部41和连接于相邻两个所述第一承载部41之间的第一连接部42,所述第一承载部41环绕于所述线束承载部61的外部。所述第一连接件4是弹性的,可以随肠道的蠕动发生弹性形变,而不会给肠道施加限制压力,给肠道提供了可伸缩的运动空间。例如,所述第一连接件4可以为橡胶、硅胶等材料制成的具有一定弹性的弹性连接件。在所述第一连接部42和第一承载部41均具有弹性时,所述第一承载部41的弹性可以小于所述第一连接部42的弹性。当给所述第一承载部41和所述第一连接部42施加相同的拉伸力时,所述第一承载部41所发生的弹性形变量可以小于所述第一连接部42所 发生的弹性形变量。从而使得第一承载部41更好地固定电磁铁2,第一连接部42可以提供更好的周向伸缩能力。
如图5所示,所述第一连接件4进一步设置有第二连接结构,所述第一连接件4可在所述第二连接结构处连接而环绕所述肠道组织9的外壁,或者在所述第二连接结构处断开而脱离所述肠道组织9的外壁。图5中示出的第二连接结构为包括在两个端部分别设置的连接凸起43和连接凹槽44,连接凸起43嵌设于连接凹槽44时,第一连接件4为环状,连接凸起43与连接凹槽44分离时,第一连接件4为条状或其他不封闭的形状。在其他可替代的实施方式中,连接结构也可以采用其他的形式,例如在两个端部分别设置连接环和连接勾,将两者勾在一起或分离实现第一连接件4的两种状态,或者两个端部设置粘接结构,通过粘接或粘接分离实现第一连接件4的两种状态等等。
如图9所示,所述第一承载部41的宽度w21大于第一连接部42的宽度w23。由此,第一承载部41可以承载宽度较宽的电磁铁2,以实现电磁铁2对保护套1更好的固定作用,并且第一连接部42的宽度较小,可以提高第一连接部42的弹性变形能力,对肠道组织9的蠕动影响大大降低。进一步地,所述第一承载部41的环形壁的宽度w22可以大于第一连接部42的宽度w23,提高第一承载部41与电磁铁2的连接稳定性。在该实施例中,如图10所示,所述第一承载部41的厚度t21和第一连接部42的厚度t22基本相等。在另一可替代的实施方式中,所述第一承载部41的厚度t21也可以大于第一连接部42的厚度t22。由此,第一承载部41可以承载厚度较厚的电磁铁2,以实现电磁铁2对保护套1更好的固定作用。并且第一连接部42的厚度较小,也可以进一步可以提高第一连接部42的弹性变形能力。此处厚度方向即相当于形成环状结构后的第一连接件4的径向方向(对应于保护套 1的径向方向)。
所述第一承载部41与所述第一连接部42一体成型,且所述第一承载部41为环绕电磁铁2的中空环状结构,即所述第一承载部41中设置有安装孔,电磁铁2嵌设于安装孔中。在其他可替代的实施方式中,所述第一承载部41也可以采用其他的形状,并且也可以与第一连接部42独立成型并固定连接。如图4所示,在所述电磁铁2的侧面上至少部分设置有周向的第一安装槽22,环状的所述第一承载部41嵌设在所述第一安装槽22中。在另一种可替代的实施方式中,也可以是所述第一承载部41的中空环状结构的边缘内侧至少部分设置有周向的安装槽,所述电磁铁2的侧面嵌设于所述安装槽中,从而实现所述电磁铁2与所述第一承载部41的稳定连接。在该实施例中,所述第一承载部41位于所述供电线束6的线束承载部61的外侧。
在该第一实施例和后述的第三实施例、第四实施例、第五实施例、第六实施例、第七实施例、第九实施例、第十实施例中,所述第一连接件4可以部分或全部采用生物可吸收材料,例如采用生物可吸收的医用薄膜制成,在保证一定强度的情况下具有柔性或具有一定的弹性。从而省去了第一连接件4在术后移除的步骤。
如图3所示,还可以进一步在保护套1的内表面设置有与所述内部固定块3一一对应的凹槽12,以更好地实现内部固定块3在保护套1内表面的定位。所述内部固定块3嵌设于所对应的凹槽12中,从而实现内部固定块3与保护套1的内表面的可拆卸固定。
在该第一实施例以及后述的第二实施例、第三实施例、第四实施例、第七实施例、第八实施例、第九实施例和第十实施例中,所述内部固定块3可以部分或全部采用生物可吸收材料,例如采用生物可吸收铁基材料,或者磁化的生物可吸收铁基 材料等等,从而省去了内部固定块3在术后移除的步骤。
如图11所示,为本发明第二实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中,所述第一固定组件不包括第一连接件。供电线束6可以同时起到固定电磁铁2和为电磁铁2供电的作用。所述供电线束6以及所述电磁铁2与所述供电线束6的配合关系可以采用上述第一实施例中的具体结构,但本发明不限于此。在其他可替代的实施方式中,所述供电线束6可以设计为其他结构,与电磁铁2可以通过其他方式连接,均属于本发明的保护范围之内。所述第二固定组件可以采用上述第一实施例中的具体结构。
如图12所示,为本发明第三实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中,所述吻合口保护装置可以用于肠道高位的吻合口保护。所述吻合口保护装置包括两个所述第一固定组件和两个所述第二固定组件,一个所述第一固定组件和一个所述第二固定组件设置于所述吻合口的上游一侧,另一个所述第一固定组件和另一个所述第二固定组件设置于所述吻合口的下游一侧。所述第一固定组件可以采用上述第一实施例、第二实施例的第一固定组件的结构,所述第二固定组件可以采用上述第一实施例、后述的第四实施例、第五实施例或第六实施例中的第二固定组件的结构。上游的第一固定组件和下游的第一固定组件的结构可以相同或不同,上游的第二固定组件和下游的第二固定组件的结构可以相同或不同。在吻合口的上游一侧的肠道组织9外壁设置有一组电磁铁2,对应地保护套1内部设置有内部固定块3,在吻合口的下游一侧的肠道组织9外壁设置有另一组电磁铁2,对应地在保护套1内部设置有内部固定块。该种结构一方面可以大大节省了所需要的保护套1的长度,并且更方便手术过程中保护套1的放置和吻合口恢复后保护套1的移除,另一方面可以更好地将保护套1固定在需要的位置,保证使用过程 中的稳定性。
如图13~16所示,为本发明第四实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中,所述第二固定组件还包括第二连接件5。所述第二连接件5安装于所述肠道组织9处时,所述第二连接件5环绕所述保护套1的内表面,而形成一个连接环状结构,从而与所述内部固定块3一起对保护套1形成一个周向的固定。所述第二连接件5与所述第一连接件4的位置相对应,形成对保护套1的固定环。如图14所示,所述第二连接件5包括第二承载部51和第二连接部52。所述第二承载部51与内部固定块3一一对应,且承载所对应的内部固定块3。所述第二连接部52连接于相邻两个所述第二承载部51之间。所述第二连接件5安装于所述肠道组织9处时,所述第二连接件5是周向可伸缩的。进一步地,所述第二连接件5可以为弹性连接件,至少其第二连接部52是具有弹性的。因此,在肠道蠕动时,第二连接件5可以随肠道的蠕动发生弹性形变,而不会给肠道施加限制压力,给肠道提供了可伸缩的运动空间。例如,所述第二连接件5可以为橡胶、硅胶等材料制成的具有一定弹性的弹性连接件。所述第二连接件5可以平行于支撑部11设置。所述第二连接件5可以是一个封闭的环状结构,也可以是一个具有接口的连接件,安装于所述肠道组织9处时,首尾相接形成连接环。在所述第二连接部52和第二承载部51均具有弹性时,所述第二承载部51的弹性可以小于所述第二连接部52的弹性。从而使得第二承载部51更好地固定内部固定块3,第二连接部52可以提供更好的周向伸缩能力。
进一步地,在该第三实施例和后述的第十实施例中,所述第二连接件5可以部分或全部采用生物可吸收材料,例如采用生物可吸收的医用薄膜制成,在保证一定强度的情况下具有柔性或具有一定的弹性。从而省去了第二连接件5在术后移除的 步骤。
如图15所示,在该实施例中,所述第二承载部51的宽度w31大于第二连接部52的宽度w33。由此,第二承载部51可以承载宽度较宽的内部固定块3,以实现内部固定块3对保护套1更好的固定作用,并且第二连接部52的宽度较小,可以提高第二连接部52的弹性变形能力,对肠道组织9的蠕动影响大大降低。进一步地,所述第二承载部51的环形壁的宽度w32可以大于第二连接部42的宽度w33,提高第二承载部51与内部固定块3的连接稳定性。在该实施例中,如图16所示,所述第二承载部51的厚度t31和第二连接部52的厚度t32基本相等。在另一可替代的实施方式中,所述第二承载部51的厚度t31也可以大于第二连接部52的厚度t32。由此,第二承载部51可以承载厚度较厚的内部固定块3,以实现内部固定块3对保护套1更好的固定作用。并且第二连接部52的厚度较小,也可以进一步可以提高第二连接部52的弹性变形能力。
如图14所示,所述第二承载部51与所述第二连接部52一体成型,且所述第二承载部51为环绕内部固定块3的中空环状结构,即所述第二承载部51中设置有安装孔,内部固定块3嵌设于安装孔中。为了更方便地将内部固定块3安装于第二连接件5和从第二连接件5中移除,所述内部固定块3与所述安装孔的内壁相贴的各个侧壁具有圆角31结构。在其他可替代的实施方式中,所述第二承载部51也可以采用其他的形状,并且也可以与第二连接部52独立成型并固定连接。如图14所示,在所述内部固定块3的侧面上至少部分设置有周向的第二安装槽32,环状的所述第二承载部51嵌设在所述第二安装槽32中。在另一种可替代的实施方式中,也可以是所述第二承载部51的中空环状结构的边缘内侧至少部分设置有第二固定块周向的第二安装槽,所述内部固定块3的侧面嵌设于所述第二安装槽中,从而实现 所述内部固定块3与所述第二承载部51的稳定连接。
在该实施例中,所述第二连接件5也可以与所述保护套1一体成型。在一种可替代的实施方式中,所述第二连接件5也可以是与所述保护套1分别成型后通过黏贴等方式固定在一起的。在另一种可替代的实施方式中,所述第二连接件5也可以是未提前固定在保护套1中,而是在手术时由医生放入到保护套1的对应位置。

如图18所示,为本发明第六实施例的吻合口保护装置应用于肠道组织的结构示意图。在该实施例中,全部或者部分所述内部固定块3的表面涂覆有磁性颗粒涂层或内部分布有磁性颗粒。各个所述内部固定块3的磁性颗粒磁性相同,且与所述电磁铁2的磁性相反。
该上述第四实施例、第五实施例和第六实施例中,第一固定组件的结构、供电 线束6的结构以及第一固定组件与供电线束的配合可以与第一实施例相同。在另一可替代的实施方式中,所述第一固定组件和/或供电线束6也可以采用其他结构,第一固定组件与供电线束的配合也可以采用其他方式。
现有技术中的固定带在环绕于肠道处之后,其对肠道的压力是固定的,无法实现调整。基于此,本发明还提供了一种供电组件输出电流可调的吻合口保护装置,通过供电组件与内部固定组件的磁性吸附,将保护吻合口的保护套固定在需要位置,通过采用输出电流可调的供电组件,可以调整供电组件产生的磁力大小,从而调整第一固定组件和第二固定组件对管状组织的压力。
如图19~25所示,为本发明第七实施例的吻合口保护装置的结构示意图。该实施例与第一实施例的区别在于供电组件的结构不同。所述吻合口保护装置包括:保护套1,位于肠道组织9内部与吻合口相对应的位置,对吻合口的内表面起到保护作用,在引导肠道内容物通过的过程中不会污染吻合口;第一固定组件,设置于所述肠道组织9的外壁,所述第一固定组件包括电磁发生部件;供电组件,用于对所述电磁发生部件供电,以使得所述供电组件通电后产生磁性,所述供电组件的输出电流可调;以及第二固定组件,设置于所述保护套1的内表面,所述第二固定组件与所述第一固定组件的电磁发生部件通过磁性吸附而相对固定。
由于该装置中只有第一固定组件和第二固定组件之间的磁性吸附位置是相对固定的,不会阻碍管状组织的正常蠕动,并且给管状组织提供周向伸缩的空间,保证吻合口附近正常的供血。第一固定组件中的供电组件可在通过供电组件供电时产生磁性。因此可以通过控制供电组件供电的通断来灵活控制供电组件中的磁性有无,并且通过采用输出电流可调的供电组件,可以调整供电组件产生的磁力大小,从而调整第一固定组件和第二固定组件对管状组织的压力。
在该实施例中,以所述电磁发生部件为电磁铁2为例进行说明。在其他可替代的实施方式中,所述电磁发生部件也可以采用其他结构,例如电磁线圈等,均属于本发明的保护范围之内。
如图19~21所示,在该实施例中,所述第一固定组件包括间隔设置的多个电磁铁2,所述多个电磁铁2沿所述肠道组织9的周向依次排布,以对所述保护套1形成一个均匀、稳定的固定。所述第二固定组件包括与所述电磁铁2一一对应的内部固定块3。所述内部固定块3可以采用自身不带磁性但可以被磁铁吸引的材料,例如铁、镍、钴等亲磁的金属及其合金等。或者,所述内部固定块3可以采用自身带有磁性的磁性材料,如磁铁等,并且磁性与所述电磁铁2通电时的磁性相反。在该实施例中,多个所述电磁铁2彼此间隔设置,多个所述内部固定块3彼此间隔设置。电磁铁2和内部固定块3的数量也可以根据需要选择设置,并且电磁铁2和内部固定块3之间可以形成一一对应的关系,一对多的关系,或者多对一的关系等等,均属于本发明的保护范围之内。在其他可替代的实施方式中,电磁铁2也可以设置为1个和/或内部固定块3也可以设置为1个。
如图20所示,所述保护套1为管状的保护套管,可以对吻合口形成周向的保护。所述保护套1可以为一个壁厚很薄的具有柔性的薄膜套管,例如橡胶薄膜套管、硅胶薄膜套管等,但本发明不限于此。在其他可替代的实施方式中,所述保护套1也可以采用其他形状,全部或部分覆盖所述吻合口的内壁,均属于本发明的保护范围之内。所述固定组件优选设置于所述吻合口的上游一侧,用来固定保护套1,使得保护套1不至于向吻合口的下游一侧运动而失去对吻合口的保护。
如图19和图20所示,所述保护套1位于所述吻合口的上游的一端设置有支撑部11,所述支撑部11在所述保护套1的径向方向可伸缩。所述支撑部11的结构和 工作方式可以与上述第一实施例中的支撑部11相同。所述第一固定组件和第二固定组件设置于所述吻合口与所述支撑部11之间,通过与支撑部11的配合可以更好地将保护套1保持在吻合口位置。
如图19所示,在该实施例中,所述供电包括供电线束6、电流调节电路71、控制元件73和输入电源72,所述输入电源72依次通过所述电流调节电路71和所述供电线束6向所述电磁铁2供电,所述控制元件73用于调节所述电流调节电路71的输出电流值,所述控制元件73可以为手动调节开关或者自动控制电路(例如采用可编程逻辑控制器PLC实现)。所述输入电源72可以采用可充电的蓄电池或者不可充电的电池等,所述电流调节电路71可以向所述供电线束6输送交流电流或直流电流,对应地,所述电磁铁2为交流电磁铁或直流电磁铁。
所述供电线束6环绕所述肠道组织9的外壁,且分别与各个所述电磁铁2电连接。所述供电线束6可以与输入电源72电连接,输入电源72通过电流调节电路71和供电线束6向电磁铁2的导电绕组供电,使得电磁铁2产生磁性。电磁铁2可以使用在通电时具有磁性,在断电时快速消磁的结构。在需要将电磁铁2固定于肠道组织9的外壁时,通过输入电源72经过电流调节电路71在供电线束6中通电,从而使得电磁铁2与内部固定块3磁性吸附。在使用过程中,供电线束6持续为电磁铁2供电。需要将电磁铁2从肠道组织9的外壁移除时,可以切断输入电源72对供电线束6的供电,使得电磁铁2失去磁性。通过所述电流调节电路71可以控制供电线束6中供电电流的大小,从而控制电磁铁2的磁性强度大小。
所述电流调节电路71可以采用多种不同的电路结构,能够实现在输入的驱动信号下输出的电流大小可调即可。例如,所述电流调节电路可以包括变压器,所述变压器的副边线圈匝数可调,所述变压器的原边线圈输入所述输入电源72的供电 电流,所述变压器的副边线圈向所述供电线束6输入供电电流,通过调节所述变压器的副边线圈匝数,可以实现调节供电电流的目的。又例如,所述电流调节电路可以包括分流电路,所述分流电路中的至少一个分流支路包括可变电阻,通过调节所述可变电阻的电阻值,可以调节所述分流电路的输出电流。

在该实施方式中,所述控制元件可以为手动的开关,也可以为自动的控制电路。例如,所述电流调节电路包括副边线圈匝数可调的变压器T时,所述控制元件为可以手动调节所述开关K的档位开关,所述档位开关的各个档位分别对应于所述开关K的可调触点的不同位置,通过调整所述档位开关,可以调节变压器T副边的线圈 匝数。在另一种实施方式中,所述控制元件也可以采用一控制电路来实现,所述控制电路可以生成控制信号控制所述开关K的可调触点与不同的输出端点O1、O2和O3之间的导通或断开,来实现调节变压器T副边的线圈匝数。

在该实施方式中,所述控制元件可以为手动的开关,也可以为自动的控制电路。例如,所述控制元件为可以手动调节各个开关管的栅极电压的开关,也可以为自动调节各个开关管的栅极电压的控制电路。

如图24和图25所示,所述吻合口保护装置还可以进一步包括信号处理组件82,所述信号处理组件82可以调节所述供电组件的驱动电流值,然后将包括所述驱动电流值的驱动信号发送至所述供电组件,所述供电组件配置为根据所述驱动电 流值控制输出电流。具体地,所述控制元件73包括可以实现自动电流控制的控制电路,所述驱动信号由所述信号处理组件82发送至所述控制元件73。所述控制元件73可以根据所述驱动信号调节所述电流调节电路71的输出电流值,例如,对于图21的结构,所述控制元件73根据所述驱动电流值和开关K的档位的关系,调节开关K的可调触点与对应的输出端点O1、O2或O3电连接,对于图22的结构,所述控制元件73根据所述驱动电流值和档位的关系,控制开关管M1、M2和M3的栅极电压,从而调节开关管M1、M2和M3的导通或关闭,实现所述电流调节电路71的输出电流可调,对于图23的结构,所述控制元件73根据所述驱动电流值和可变电阻值的关系,调节所述可变电阻的电阻值,实现所述电流调节电路71的输出电流可调。
