Description

一种夹合消化道内软组织的软组织夹 技术领域

随着科技发展的不断进步，医学技术的不断发展，人们对于身体内部病变的治疗技术也越来越先进、越来越高科技，而对于消化道内的病变，人们往往会使用通过内窥镜下器械进行手术治疗，然而其中很多手术都会造成治疗区域出血。阻止治疗区域出血可以加快伤口的愈合、使术后消化道内软组织愈合速度变快，进而使所述组织夹从体内脱落排出。
软组织夹可抓紧出血组织的边缘阻止出血，而根据相关文献记载，如日本特开2002-191609号公报及日本特开2004-121485号公报而公知的软组织夹，通过夹子组件以及推送系统两部分，通过推送系统中的相应地部件控制夹子组件的抓取方向、抓取部位，并通过夹子组件相应地控制装置使夹子抓紧软组织，并使夹子留在组织体内。

进一步地，如图2所示，所述发生断裂的部位优选地为图中断裂部41的位置，进一步地，所述断裂的部位选取是根据千百次临床实验的结果，进一步地，所述套筒、夹子以及断裂部材料等将留在生物体体内，若所述断裂部位于所述拉杆基端远离所述拉杆前端的位置，则发生断裂后，所述留在体内的杂质会相对较多，不利于病人的康复。
本领域技术人员理解，在上述优选地变化例中，所述断裂部优选地为一横截面，而不是一个所述孔柱上的洞状结构，所述断裂部由树脂材料制成，在这样的实施例中，当所述拉杆基端44在受到一定作用力时，发生断裂，从而使所述套筒3以及夹子5与所述推送系统2分离。进一步地，所述拉杆基端44在受到挤压时不会断裂，只有在 受到拉伸时，才会断裂。
更进一步地，结合上述优选实施例，本领域技术人员理解，所述拉杆基端44上靠近拉杆前端42的部位的横截面积小于所述拉杆基端44其他部位的横截面积，相应地，所述拉杆前端42上靠近所述拉杆基端44的部位的横截面积小于所述拉杆前端42其他部位的横截面积。在这样的实施例中，所述拉杆基端至所述拉杆前端的横截面积形成了先变小再变大的过程，导致所述横截面积较小处的抗拉能力小于所述横截面积较大处的抗拉能力，进一步地，形成了所述断裂部。更为具体地，在一个优选地实施例中，所述断裂部位于所述拉杆基端上，拉杆基端断裂部位的横截面积小于所述拉杆基端其它部位的横截面积，而所述断裂部的形状与所述拉杆前端的凹状形状相适应，则所述拉杆前端的横截面积与所述断裂部的横截面积并没有对应的关系，但这并不影响本发明的技术方案，在此不予赘述。
更进一步地，所述断裂部的中部或者整体为锯齿状。本领域技术人员理解，所述断裂部可以仅仅是由所述锯齿状结构形成的，在这样的变化例中，如图8所示，若所述断裂部的中部为锯齿状，则所述断裂部的横截面积小于所述拉杆基端上其他位置的横截面积，而在另一个优选地变化例中，如图9所示，若所述孔柱整体呈现一排锯齿状结构，则发生断裂的地方可以为多处，这并不影响本发明的具体实施方式，在此不予赘述。
进一步地，上述中的断裂部41采用树脂材料从而产生断裂，而在一个优选地变化例中，所述断裂的方式还可以有很多种，具体地，比如。所述断裂部41为所述拉杆基端44的一部分，所述拉杆前端42以及所述拉杆基端44)的横截面积大于所述断裂部41的横截面积，且由所述拉杆前端42均匀过渡至所述断裂部后再均匀过渡至所述拉杆基端44，在这样的实施例中，所述拉杆前端42至所述拉杆基端44形成了一个两头粗、中间细的结构，进一步地，当拉动所述拉杆构件4时，中间细的部分能承受的拉力小于所述两头粗部分，进而在施加很大力气时，所述中间细的部分会优先发生断裂。
而在另一个优选地变化例中，所述断裂部41采用与所述拉杆前端42以及所述拉杆基端44相比抗拉性弱的材料，而在这样的实施例中，由于断裂部部位的抗拉性弱，在拉动所述拉杆构件4时，所述断裂部41优选地发生断裂。更进一步地，本领域技术人员理解，所述断裂部41还可以采用细绳，这都不影响本发明的技术方案，在此不予赘述。
本领域技术人员理解，所述拉杆前端42采用硬质材料，所述拉杆前端42与所述夹子5连接，更为具体地，所述拉杆前端42具有一卡槽，所述卡槽可以卡住并固定所述夹子5的基端，进一步地，所述固定将在后述的具体实施方式中作详细描述，在此不予赘述。进一步地，为了使所述夹子5在被拉入所述套筒3的过程中不会因为拉力过大而造成偏向力的转移以及夹子5的加紧方向的转移，所述拉杆前端42优选地采用硬质材料，在这样的变化例中，无论所述拉杆构件4使用多大的力拉动所述夹子5，所述拉杆前端42都不会变形。
图3示出根据本发明的具体实施方式的，在一种夹合消化道内软组织的软组织夹中，所述操作部的剖面结构示意图，所述操作部7包括推动部71以及锥形头72，其中，所述推动部71为中间环形内凹陷的圆柱形中空结构，所述推动部71可在一直杆73上特定区域内左右滑动，所述直杆73为中空结构，所述直杆73连接所述挠性组件6的基端。
本领域技术人员理解，所述推动部71可以在所述直杆73上左右滑动，具体地，所述推动部71还可以自由转动，具体地，所述直杆上所述滑动区的外壁形状与所述推动部71的中空结构内壁形状大小相适应，在这样的实施例中，所述滑动区的横截面积优选地小于所述直杆其他部位的横截面积，所述直杆一端连接一手柄拉杆，一端连接于所述挠性组件6的基端，进一步地，本领域技术人员理解，所述直杆是中空结构，所述挠性组件也是中空结构。
进一步地，所述推动部71的圆心处固定有一导丝74，所述导丝 74穿过所述直杆73以及挠性组件6，与所述锥形头72末端相连。如图3所示，所述推动部71为中间环形内凹陷的圆柱形中空结构，所述推动部71通过焊接、粘结等方式固定所述导丝，所述导丝74优选地为一较细的金属直杆，所述导丝一端固定所述推动部71，另一端穿过所述直杆73的中空结构以及所述挠性组件6的中空结构，并与所述锥形头72的末端相连接。在这样的实施例中，使用者通过推动所述推动部71，使所述推动部71在所述直杆73，所述推动部71带动所述导丝74移动，所述导丝74带动所述锥形头72移动，所述锥形头72连接所述拉杆构件，进一步地，所述推动部71带动所述拉杆构件移动。
进一步地，所述操作部7包括推动部71以及锥形头72，所述锥形头72的后部的形状与所述中空结构相适应并被置于所述中空结构内且所述锥形头72的前部伸出所述中空结构后连接所述拉杆基端44，从而控制所述夹子组件1。本领域技术人员理解，可以在所述推动部71上设置有手拉环以及控制方向的推动杆，用于控制所述夹子的上下、左右移动，这并不影响本发明的技术方案，在此不予赘述。所述锥形头72用于连接所述拉杆基端44，进一步地，所述锥形头72的形状为前部较尖逐渐过渡到后部内径较大的结构，而上述挠性组件中的中空结构的内径与所述锥形头尾部的内径大小相适应，进一步地，所述锥形头72的前部伸出所述中空结构并与所述拉杆前端相连接。更进一步的，通过拉动所述推动部71带动所述锥形头72，从而带动所述拉杆基端44移动。
本领域技术人员理解，在另一个变化例中，所述锥形头72的后部即为所述直杆，在这样的实施例中，所述锥形头72的后部固定于所述推动部71，所述推动部71带动所述锥形头72移动，所述锥形头72带动所述拉杆构件4移动。进一步地，所述推动部71可以为对称的细直杆，在这样的实施例中，所述推动部71连接所述锥形头的尾部两侧，通过对所述细直杆施加外力，从而带动所述拉杆基端。所述推动部71还可以为对称的可供手指伸入的指环，在这样的实施例中， 操作者通过手指勾住所述指环从而带动所述拉杆基端移动，或者为环形挡板，所述环形挡板360度或小于360度环绕所述挠性组件6的外表面。所述推动部71还可以位于所述锥形头的尾部。
进一步地，所述拉杆基端44末端设有弹性孔，在所述锥形头72进入所述弹性孔的过程中，所述弹性孔张开，到所述锥形头72全部没入后所述弹性孔闭合，使得所述锥形头72固定于所述弹性孔内。本领域技术人员理解，所述拉杆基端44末端的弹性孔最大半径稍微大于所述锥形头72的最大半径，在这样的实施例中，随着锥形头72逐渐进入所述弹性孔，所述弹性孔逐渐张开，但当所述锥形头72全部进入所述弹性孔时，所述锥形头72的半径骤然变小，使得所述弹性孔自然闭合，使得所述锥形头72固定于所述弹性孔内。
图4示出根据本发明的具体实施方式的，在一种夹合消化道内软组织的软组织夹中，所述套筒的侧视结构示意图，如图4所示，所述套筒3靠近所述拉杆基端44一侧设置有弹性卡翼32，所述弹性卡翼32从所述套筒3的筒道31内臂斜向延伸而出，所述弹性卡翼32可沿所述套筒3径向弹性开闭；在不工作状态下，所述弹性卡翼32被一密封装置包裹，处于闭合状态，在工作状态下所述弹性卡翼32向外弹出并凸出于所述套筒3的外壁后与所述推送系统2的前部卡合。
本领域技术人员理解，所述弹性卡翼32固定于所述套筒3外壁上两侧，进一步地，所述弹性卡翼32从所述套筒3的筒道31内臂斜向延伸而出，所述延伸斜出方向指向所述推送系统方向，进一步地，所述弹性卡翼32可沿所述套筒3径向弹性开闭，本领域技术人员理解，所述弹性卡翼32在没有外力作用下，将处于开合状态，而在本发明中，所述弹性卡翼32在不工作状态下，被一密封装置包裹，并处于闭合状态。所述密封装置是根据所述夹和消化道内软组织夹的外观形状浇筑而成，所述密封装置卫生、一次性并能固定所述软组织夹的形状防止所述软组织夹不被外力挤压而产生变形。进一步地，所述 弹性卡翼32的两个卡翼均被所述密封装置的内壁所抵住而处于闭合状态。
进一步地，在工作状态下所述弹性卡翼32向外弹出并凸出于所述套筒3的外壁后与所述推送系统2的前部卡合。如图1所示，所述弹性卡翼32在被推出所述密封装置后，会进入所述推送系统2中，具体地，所述弹性卡翼32会被所述推送系统2的相应部件的外壁所挤压而处于闭合状态，而再将所述套筒3推出所述推送系统2时，所述套筒3中的弹性卡翼32会自然张开，此时，若在拉动所述套筒3时，所述套筒3的外壁后与所述推送系统2的前部卡合。本领域技术人员理解，所述套筒3的工作原理将在后述的具体实施方式中作详细阐述，在此不予赘述。
优选地，所述弹性卡翼32与所述套筒3的结构关系为360度结构，在这样的实施例中，所述弹性卡翼32呈围绕所述套筒3的环状结构，当拉紧所述套筒3的弹性卡翼32贴合所述推送系统2时，所述环状结构卡翼凸起将与所述推送系统卡合。
而在另一个优选地变化例中，所述弹性卡翼32为小于360度的结构，即仅仅在所述套筒3的部分筒道31的部分延伸所述弹性卡翼32。而在这样的实施例中，所述弹性卡翼32分为多个部分，具体地，所述弹性卡翼32可以为2个相互对称的结构，进一步地，所述弹性卡翼32还可以为4个、6个、9个或者更多，这都不影响本发明的技术方案，在此不予赘述。
进一步地，本领域技术人员理解，在所述拉杆构件4的拉杆前端42与所述拉杆基端44之间还存在一凸起部位，所述凸起部位与夹子末端之间的距离与所述套筒的长度相适应，所述套筒3相对固定的被设置于所述夹子5的末端以及所述拉杆构件上凸起部位处。进一步地，所述凸起部位可以固定所述套筒3，使所述套筒3不会向后移动。
本领域技术人员理解，结合图1至图4所示出的具体实施方式，主要描述了当所述软组织夹处于工作状态的初始阶段的结构、原理以及所述拉杆构件4、套筒3的结构。在这样的实施例中，优选地，所 述拉杆构件4的拉杆前端42通过焊接的方式连接所述夹子5，本领域技术人员理解，在通过拉动所述拉杆构件4，从而带动所述夹子5移动的过程中，往往需要使用很大的力，进一步地，需要牢牢稳固偶数拉杆构件4以及所述夹子5，通过所述焊接的方式能够有效地固定住所述拉杆构件4以及所述夹子5。
而在另一个优选地变化例中，所述拉杆构件4的拉杆前端42通过紧锁螺母的方式进行固定，具体地，可以在所述拉杆前端42处设置有螺孔，而在所述夹子基端设置有螺丝，进而拧紧固定，还可以通过卡簧卡销或者粘结的方式，这都不影响本发明的技术方案，在此不予赘述。
图5示出根据本发明的具体实施方式的，在一种夹合消化道内软组织的软组织夹中，所述挠性组件以及部分操作部的结构示意图，如图5所示，所述推送系统2包括挠性组件6、操作部7；其中，所述挠性组件6为一中空结构，所述拉杆构件4穿过所述中空结构，所述操作部7伸入所述中空结构并与所述拉杆构件4的拉杆基端44相连接。
本领域技术人员理解，上述中的操作部7主要包括了推动部部分以及锥形头部分，进一步地，在图4中并未示出所述推动部部分，但这并不代表所述软组织夹不具有所述推动部，在此不予赘述。具体地，图4中示出了所述操作部7的锥形头72，所述锥形头72用于连接所述拉杆基端的弹性孔，这将在后述的具体实施方式中作详细阐述，在此不予赘述。进一步地，所述图5示出了所述挠性组件6，本领域技术人员理解，所述挠性组件6可以理解为一弹簧装置，所述推动部71通过控制穿过所述挠性组件的锥形头后部，从而控制拉杆构件4。
而在这样的实施例中，所述操作部7主要是指所述锥形头部分，所述推动部部分以及所述锥形头部分将在后述中作详细的描述，所述锥形头连接所述拉杆基端44，进一步地，所述推送系统2包括挠性组件6以及操作部7，所述挠性组件6为一类似于弹簧的装置，所述挠 性组件6用于贴合所述套筒3，进一步地，所述弹簧管为可以弯曲管，所述推送系统2可以根据所述挠性组件6这一特性调整所述夹子的方向，从而更加容易的对所述软组织进行抓取。
进一步地，所述拉杆基端44末端设有弹性孔，在所述锥形头72进入所述弹性孔的过程中，所述弹性孔张开，到所述锥形头72全部没入后所述弹性孔闭合，使得所述锥形头72固定于所述弹性孔内。本领域技术人员理解，所述拉杆基端44末端的弹性孔最大半径稍微大于所述锥形头72的最大半径，在这样的实施例中，随着锥形头72逐渐进入所述弹性孔，所述弹性孔逐渐张开，但当所述锥形头72全部进入所述弹性孔时，所述锥形头72的半径骤然变小，使得所述弹性孔自然闭合，使得所述锥形头72固定于所述弹性孔内。
优选地，所述套筒3外径小于挠性组件6的顶端部61的开口内径，在工作状态的初始阶段，所述拉杆构件4通过推动部的外力作用被拉动，同时带动所述套筒3伸入所述挠性组件6。进一步地，上述中所指的套筒3外径是指所述弹性卡翼处于闭合状态时的外径，具体地，所述套筒3外径小于挠性组件6的顶端部61的开口内径，使得所述套筒3可以进入到所述挠性组件6内，进一步地，本领域技术人员理解，所述拉杆构件4的前端拉杆前端42优选地连接所述夹子5，在工作状态的初始阶段，所述夹子5处于张开状态，所述夹子5的爪壁与所述套筒外壁边缘相接触，进一步地，当拉动所述拉杆构件时，所述夹子5的爪臂给所述套筒3提供了朝拉杆构件运动方向的作用力，从而带动所述套筒3运动，进一步地，所述套筒3伸入到所述挠性组件6内的中空结构中。
进一步地，所述软组织夹还包括一个密封装置，所述密封装置至少包裹所述套筒3，且使得所述套筒3的弹性卡翼32在进入所述工作状态之前处于闭合状态，且在工作状态的初始阶段，所述拉杆构件4被拉动带动所述套筒3伸入所述挠性组件6之后，所述密封装置被剥离。
进一步地，在一个优选地变化例中，所述密封装置包裹所述套筒 3，在所述密封装置初始阶段，所述弹性卡翼处于张开状态，所述密封装置内部形成一种圆锥形结构，进一步地，所述圆锥形结构具有渐变径结构，随着所述套筒在所述密封装置内的移动，所述渐变径越来越小，所述弹性卡翼收到来自所述密封装置内壁的作用力而逐渐闭合，最终使得所述弹性卡翼处于闭合状态，并以闭合状态进入所述挠性组件中。
本领域技术人员理解，所述密封装置即为所述软组织夹的一次性包装外壳，所述外壳不仅仅将所述套筒3包裹，具体地，所述外壳根据所述软组织夹的外观形状，形成了一层覆盖在所述软组织夹上的硬胶材料，可有效地保护所述软组织夹。进一步地，所述拉杆构件4带动所述套筒3移动时，所述套筒3正逐步地与所述外壳分离，本领域技术人员理解，所述套筒3相对固定的被置于所述密封装置内，需要一定的拉力才能将所述套筒3以及爪子带出，而在这种情况下，所述拉力并未达到分裂断裂部所需要的拉力。当所述套筒完全进入到所述挠性组件6之后，所述密封装置被剥离。
更进一步地，在所述套筒3被拉入所述挠性组件6后，通过反向推动所述拉杆构件4将所述套筒3推出所述挠性组件6，此时，所述弹性卡翼32张开，使得所述套筒3与所述推送系统2的前部卡合，然后，再拉动所述拉杆构件4使得所述拉杆构件4的断裂部41断裂。本领域技术人员理解，由于所述套筒3外径小于挠性组件6的顶端部61的开口内径，使所述套筒3能够进入所述挠性组件6的中空结构中，进一步地，所述套筒3的弹性卡翼32在未进入所述挠性组件6中时，处于闭合状态，而当所述套筒3进入到所述挠性组件6后，所述套筒3外表面上的弹性卡翼32被所述挠性组件6内壁所挤压，也处于闭合状态，而在推动所述拉杆构件4时，所述套筒3从进入所述挠性组件6的一端出来，此时，所述弹性卡翼32将不在受到任何外力作用而展开，此时，在拉动所述拉杆构件时，所述套筒3与所述推送系统2的前部卡合。更进一步地，随着力量的逐渐增加，当所述拉力大于所述断裂部41所能承受的最大拉力时，所述断裂部41断裂，从而使所述 夹子组件分离。
进一步地，本发明将结合图6至图8对所述夹子5作进一步地说明，具体地，图5示出根据本发明的具体实施方式的，在一种夹合消化道内软组织的软组织夹中，所述夹子组件的立体结构示意图；以及图7示出根据本发明的具体实施方式的，在一种夹合消化道内软组织的软组织夹中，所述夹子组件的剖面结构示意图。在这样的实施例中，如图6以及图7所示，所述拉杆构件4的拉杆基端44连接所述推送系统2中的锥形头，所述拉杆构件4穿过所述套筒3，并在所述拉杆前端上优选地焊接有所述夹子5，进一步地，在所述拉杆构件前端与所述拉杆构件基端之间存在断裂部，在工作初始状态下，当拉动所述拉杆构件4时，所述套筒3的弹性卡翼卡合上述的挠性组件而使得所述夹子相对于所述套筒3运动，在这样的实施例中，在拉动所述拉杆构件4的过程中，所述夹子在外力作用下闭合，并加紧软组织，进一步地，当力度到达所述断裂部所能承受的最大拉力时，所述断裂部断裂，进一步地，所述夹子5以及所述套筒等装置与所述推送系统2脱离，进一步地，所述夹子5留在了生物体内部。
进一步地，如图8所示，所述夹子5至少包括两个弹性爪臂51，所述弹性爪臂51可抓紧夹合消化道内软组织，所述夹子5在拉力作用下向套筒3筒道31中移动，使张开的爪53闭合。如图6以及图7所示，所述拉杆前端42固定与所述夹子5的爪基端52处相连接，优选地，采用焊接的方式使其固定，进一步地，爪中段51与爪后段54相连接并形成一定角度，所述角度在150度至170度之间，所述爪前段53与所述爪中段51相连接并形成一定角度，所述角度在120度至150度之间，更进一步地，所述爪前段53、爪中段51以及爪后段54在一个平面内形成一个爪状结构，通过所述爪状结构能够更容易对所述软组织进行抓取缝合。
进一步地，所述夹子5在拉力作用下向套筒3筒道31中移动，使张开的爪53闭合。在所述夹子5进入所述套筒3的过程中，所述 爪后段54进入所述套筒3中，进一步地，所述爪后段54在所述套筒3的外壁偏向力作用下，慢慢闭合收拢，从而使所述张开的爪53闭合。
进一步地，所述弹性爪臂51具有加强筋结构。进一步地，本领域技术人员理解，如图6所示，在所述爪中段51以及所述爪后段54的外表面上，有部分凸起、部分凹陷，具体地，如图6所示，图6中示出了所述夹子的上爪以及下爪，所述弹性爪臂的上爪部分凸起于所述弹性爪臂51的外表面，所述弹性爪臂的下爪部分凹入所述弹性爪臂51的内表面。在这样的实施例中，所述设计可以更加稳定的抓取所述消化道内的软组织而不产生形变。
以上对本发明的具体实施例进行了描述。需要理解的是，本发明并不局限于所述特定实施方式，本领域技术人员可以在权利要求的范围内做出各种变形或修改，这并不影响本发明的实质内容。
