Description

组织捆扎装置 技术领域
本发明涉及一种腔镜手术器械，特别是用于腔镜手术中对组织进行捆扎的组织捆扎装置。
背景技术
随着腔镜技术的发展，越来越多的手术在腔镜手术下完成，包括非常多的恶性肿瘤手术也是在腔镜下完成，其中包括晚期宫颈癌的全子宫切除手术。类似于宫颈癌晚期手术临床选择术式时，通常采取的是全宫切除，在进行晚期宫颈癌的全子宫切除手术时，通常是将输卵管切断游离子宫后，再将宫颈外侧的阴道切断，然后将切除的子宫经阴道取出。在这类的手术中，因为肿瘤或癌细胞生长在宫颈、阴道等腔体内壁上，当利用腹腔镜进行手术时，由于形成气腹压的二氧化碳气流的流动，如果腔体内的肿瘤或癌细胞发生泄露，就容易造成癌细胞在腹腔内的播种。现有技术对这个问题没有有效的解决方法，因此临床上建议进行开腹手术，以避免癌细胞在随二氧化碳气流的流动而在腹腔内的播种。
因此，需要开发一种组织捆扎装置，在手术时，能对腔体的安全部位进行捆扎，完全封闭腔体通道，从而完全避免癌细胞扩散，然后再在安全部位进行组织切断，并将切除的组织取出。本发明的目的就在于设计一种能用于腔镜手术下的组织捆扎装置。
发明内容
本发明之组织捆扎装置，由于设计有导向机构，本发明之组织捆扎装置可以在展开状态下通过穿刺器进入人体，然后在人体内的小空间下通过导向机构的导向作用非常顺利地形成组织捆扎孔，对组织进行捆扎、封闭处理。
本发明之组织捆扎装置，其特征在于：所述组织捆扎装置100含捆扎机构1和固定机构2；
A、所述捆扎机构1上设有至少1个定位凹槽11；
B、所述固定机构2含通孔21和至少1个定位凸阶22；
C、所述捆扎机构1的近端101连接在所述固定机构2上，所述捆扎机构1的远端102能穿过所述通孔21；所述定位凸阶22镶嵌在所述定位凹槽11内时能阻止所述捆扎机构1的远端102从所述固定机构2中松弛或滑脱。
本发明之组织捆扎装置的捆扎机构1的远端102穿过所述通孔21后形成能捆扎组织的捆扎孔3，将需要捆扎的组织或取物袋等器械置入所述捆扎孔3后，夹持住所述固定机构2，继续拉动所述捆扎机构1，所述捆扎孔3收拢，即可将组织或取物袋等器械捆扎、封闭，有效防止组织取出过程中血液或组织液的溢出。
进一步，所述捆扎机构1是捆扎带1-1。所述捆扎机构1优选的是具有一定表面积的捆扎带1-1，可以更好地保证捆扎过程的牢固性，而又不会轻易将要捆扎的组织切割断裂。当然，本领域的技术人员也可以将所述捆扎机构1设计成链条状结构、珠链状结构等各种其它的结构的捆扎装置，都并不脱离本申请的保护范围。
进一步，所述捆扎带1-1是弧形带1-11。所述捆扎带1-1可以进行预定型，优选地，预定型成弧形带结构，这样在捆扎过程中，所述捆扎带1-1可以很方便地对准所述通孔21，操作过程更加方便。
所述捆扎带1-1采用柔软的弹性医用材料制成。柔软的弹性材料在保证捆扎牢固性的同时，可以更好地贴合组织，进一步保证腔道封闭的可靠性。
所述定位凹槽11是可以连续调节的连续定位凹槽11-1。所述定位凹槽11是连续定位凹槽11-1，这样在收拢所述捆扎孔3的过程中，可以根据组织大小及需要捆扎紧张的程度，固定在任何位置。
所述定位凹槽11是只能单向运动的单向运动凹槽11-2。单向运动的设计，可以保证在临床使用过程中所述捆扎机构1只能向一个方向运动，不会反向运动造成组织捆扎过程意外松脱。
所述组织捆扎装置100还含有导向机构4。所述导向机构4可以将所述捆扎机构1非常方便地导入所述通孔21内，形成所述捆扎孔3。
所述导向机构4是楔形导向机构41。

通常，所述导向头41-1是锥形、圆弧形或子弹头形等具有导向作用的形状的结构。当然，本领域的技术人员也可以设计成其它形状的导向头结构，都并不脱离本申请的保护范围。
所述导向锥孔41-2具有一定的锥度，临床使用时，夹持住所述捆扎机构1，将所述导向头41-1置入所述导向锥孔41-2内，所述导向头41-1沿着所述导向锥孔41-2的导向面41-21能非常容易地穿过所述通孔21。
所述导向机构4是磁导向机构42。所述导向机构4还可以是磁性导向机构，利用磁铁的吸引力，将所述捆扎机构1顺利地穿过所述通孔21，形成所述捆扎孔3。
所述磁导向机构42是磁铁和磁性金属构成的导向机构，所述磁导向机构42含磁体42-1和磁性金属引导机构42-2；所述磁体42-1和磁性金属引导机构42-2分别设置在所述捆扎机构1的远端102和所述固定机构2靠近所述通孔21处。
所述磁体42-1包埋在医用塑料内。因磁体42-1是铁基材料，不能直接接触人体组织，因此，需要用医用材料将所述磁体42-1包埋住，以防止其直接接触人体组织，保证手术过程的安全性。
优选地，将所述磁体42-1包埋在所述固定机构2内并靠近所述固定机构2的近端，将所述捆扎机构1的远端102用磁性金属制造构成所述磁性金属引导机构42-2。临床使用时，用手术器械夹持住所述捆扎机构1的远端102向所述固定机构2靠近，在设置在所述通孔21旁边的所述磁体42-1的磁性吸引力作用下，由磁性金属制成的所述捆扎机构1的远端102自动穿过所述通孔21向所述磁体42-1靠近，完成所述捆扎机构1的对位。
所述磁导向机构42是由不同磁极构成的磁性对；所述磁导向机构42含2个磁铁42-3；2个所述磁铁42-3分别设置于所述捆扎机构1的远端102和所述固定机构2靠近所述通孔21处，且2个所述磁铁42-3相接近的磁极分别为N极和S极。
除了由磁铁和磁性金属构成的磁性导向方式外，还可以利用不同磁极相互吸引的原理制成磁性对的磁性导向机构42。将磁铁对分别包埋在所述捆扎机构1的远端102和所述固定机构2上，并将所述磁铁42-3相对的磁极分别固定为相吸的N极和S极。所述磁铁42-3的N极和S极既可以设置在所述捆扎机构1上，也可以设置在所述固定机构2上。
优选的，设置在所述固定机构2上的磁铁42-3是包埋在所述固定机构2里的环形磁铁42-31，所述环形磁铁42-31设置在所述通孔21的外侧。
临床使用时，用手术器械夹持住所述捆扎机构1的远端102向所述固定机构2靠近，在所述磁铁42-3的磁极的相互吸引作用下，所述捆扎机构1的远端自动穿过所述通孔21，完成所述捆扎机构1和所述固定机构2之间的对位。
所述捆扎机构1的远端102设有方便手术器械夹持的夹持机构12。为方便所述捆扎机构1的对位和穿过所述通孔21后的进一步拉紧，所述捆扎机构1的远端上设有所述夹持机构12，所述夹持机构12可以保证手术器械夹持住所述捆扎机构1时不容易松脱，提高 手术扎紧操作的精准性。

所述捆扎机构1上设有防滑装置13。本发明之组织捆扎装置，当对组织捆扎完成后，临床使用中，需要在被捆扎的组织附近进行各种手术操作，在整个临床手术过程中，本发明之组织捆扎装置不能从组织上脱落，因此，本发明之组织捆扎装置在所述捆扎机构1上设有防滑装置13，其核心目的就在于防止手术过程中所述组织捆扎装置100从被捆扎在组织上滑脱。
所述防滑装置13是设置在所述捆扎机构1上的防滑纹13-1、或防滑凸阶13-2。申请人在此只列举了上述2种具体防滑结构，实际应用中，本领域的技术人员可以根据需要设计出不同的防滑结构，但都不脱离本申请的保护范围。
所述防滑纹13-1沿所述捆扎带1-1的纵向分布。因所述捆扎带1-1上的连续定位凹槽11-1具有防止横向滑脱的作用，因此，所述防滑装置13的重要作用是防止所述组织捆扎装置100沿组织轴向滑脱，因此，所述防滑纹13-1通常沿所述捆扎带1-1的纵向分布。
所述固定机构2上设有方便手术器械夹持的夹持部23。临床使用过程中，需要用手术器械夹持住所述固定机构2才能对所述捆扎机构1进行抽拉、收拢，因此，所述固定机构2上需要设有方便手术器械夹持的夹持部23。
所述夹持部23是设置在所述固定机构2外部的夹持位23-1、或夹持拉环23-2、或夹持槽23-3。所述夹持部23可以是设置在所述固定机构2上或连接在所述固定机构2上的各种可夹持结构，申请人在此只列举了上述3种具体结构，实际应用中，本领域的技术人员可以根据需要设计出不同的夹持结构，都并不脱离本申请的保护范围。
所述夹持槽23-3的中间是可夹持多边形23-31，在两端设有防滑的挡块23-32。
进一步，所述可夹持多边形23-31是六面体。这种两边凸起、中间凹下的H型六面体的凹槽结构，是方便腹腔镜手术钳夹持的具体夹持槽23-3中的一种优化结构。在具体产品设计中，本领域的技术人员可以根据需要设计出不同的多边形结构，都并不脱离本申请的保护范围。
所述组织捆扎装置100采用医用材料制造。因本发明之组织捆扎装置需要进入人体进行使用，因此，与人体接触的部位都需要采用医用材料制造，以保证临床使用的生物相容性要求。
临床使用时，首先将组织底部游离，再用手术器械将所述组织捆扎装置100在展开状态下从穿刺器通道或人体自然腔道置入需捆扎的部位，将所述捆扎机构1从需要捆扎的组织下部穿过，然后用一把手术器械夹持住所述固定机构2，另一把手术器械夹持住所述捆扎机构1的远端102，将所述捆扎机构1的远端102穿过所述固定机构2的通孔21后继续拉动所述捆扎机构1，直至将组织捆扎、封闭。
本发明之组织捆扎装置含捆扎机构1和固定机构2。所述捆扎机构1的近端101连接在所述固定机构2上，所述捆扎机构1的远端102穿过所述固定机构2的通孔21后形成捆扎孔3，所述固定机构2上的定位凸阶22镶嵌在所述捆扎机构1上的定位凹槽11内，可以防止所述捆扎机构1从所述固定机构2内松脱或滑落，形成对组织的有效捆扎和封闭，有效防止肿瘤细胞的移植。所述导向装置4有楔形导向机构41和磁性导向机构42等多种结构，所述导向装置4可以方便地将所述捆扎机构1的远端102穿过所述固定机构2的通孔21，临床使用非常方便。

优选地，将所述磁体42-1包埋在所述固定机构2内并靠近所述固定机构2的近端，将所述捆扎机构1的远端102用磁性金属制造构成所述磁性金属引导机构42-2。临床使用时，用手术器械夹持住所述捆扎机构1的远端102向所述固定机构2靠近，在设置在所述通孔21旁边的所述磁体42-1的磁性吸引力作用下，由磁性金属制成的所述捆扎机构1的远端102自动穿过所述通孔21向所述磁体42-1靠近，完成所述捆扎机构1的对位。
参考图5至图6-1，所述磁导向机构42也可以是由不同磁极构成的磁性对；所述磁导向机构42含2个磁铁42-3；2个所述磁铁42-3分别设置于所述捆扎机构1的远端102和所述固定机构2靠近所述通孔21处，且2个所述磁铁42-3相接近的磁极分别为N极和S极。
除了由磁铁和磁性金属构成的磁性导向方式外，还可以利用不同磁极相互吸引的原理制成磁性对的磁性导向机构42。将磁铁对分别包埋在所述捆扎机构1的远端102和所述固定机构2上，并将所述磁铁42-3相对的磁极分别固定为N极和S极。所述磁铁42-3的N极和S极既可以设置在所述捆扎机构1上，也可以设置在所述固定机构2上。
临床使用时，用手术器械夹持住所述捆扎机构1的远端102向所述固定机构2靠近，在所述磁铁42-3的磁极的相互吸引作用下，所述捆扎机构1的远端自动穿过所述通孔21，完成所述捆扎机构1和所述固定机构2之间的对位。
参考图6-2和6-3，优选的，设置在所述固定机构2上的磁铁42-3是包埋在所述固定 机构2里的环形磁铁42-31，所述环形磁铁42-31设置在所述通孔21的外侧。
所述磁导向机构42能将所述捆扎机构1的远端102自动地和所述固定机构2的通孔21进行对位，临床使用时操作更加方便。
申请人在此只具体列举了上述2种磁性导向结构，但本领域的技术人员可以根据需要设计出不同的磁性导向结构，申请人在此不一一列举，但都不脱离本申请的保护范围。
应该注意，本文中公开和说明的结构可以用其它效果相同的结构代替，同时本发明所介绍的实施例并非实现本发明的唯一结构。虽然本发明的优先实施例已在本文中予以介绍和说明，但本领域内的技术人员都清楚知道这些实施例不过是举例说明而己，本领域内的技术人员可以做出无数的变化、改进和代替，而不会脱离本发明，因此，应按照本发明所附的权利要求书的精神和范围来的界定本发明的保护范围。
