Description

说 明 书 一种可自动打荷包的圆形荷包钳
技术领域 本发明涉及医疗器械领域,特别是涉及一种可自动打荷包的圆形 荷包钳。 背景技术 在外科手术中,自从 20世纪 60年代发明第一把缝钉类产品以来, 医用吻合器已成为辅助刀口缝合过程中必不可少的一种医疗器械。 随着医学的发展和医疗器械产品的研发,越来越多的缝钉类产品 被应用于临床。 该类产品的适用范围已涉及到胃肠外科、 肝胆外科、 胸外科、 泌尿外科、 妇产科等领域, 成为医生必不可少的工具之一。 该类工具的应用对于患者而言, 具有术中出血较少、手术时间较短的 优点, 并且用器械代替手工可减少由于手工而造成的误差、 感染, 从 而使患者术后恢复更快。 医生在做消化道端端吻合时, 经常使用管型吻合器来操作。 在吻 合前必须在一端对组织进行荷包缝合来植入管型吻合器的抵钉座,以 便在置入中心杆后能够牢固结扎, 然后才能实施组织吻合手术。 目前 很多医生是手工缝合荷包, 这样无法保证荷包处组织的量是否合适, 如果残留组织过多会造成吻合器击发失败; 如果过少, 则吻合后会有 瘘的风险。 因此, 在使用过程中, 医生愈来愈多的使用荷包钳来缝合 荷包, 该器械性能的好坏直接影响手术进程,对于手术效果起着非常 重要的作用。 目前实际使用的荷包钳主要有两种类型,一种是直线型全金属手 动荷包钳, 另一种是直线型缝钉式自动荷包钳。 对于直线型手动荷包钳,需要以一根尾部带有缝线的缝针穿过夹 有组织的钳口进行手动荷包缝合。 手术时先把组织用钳口夹住, 然后 锁紧槽口,人体组织会自然的被夹紧并有一部分组织挤入槽口空隙内, 此时从荷包钳的一端用一根尾部带线的缝针穿入荷包钳的上部圓孔 内, 从另一侧拔出, 然后针掉头, 再从荷包钳的下部圆孔内穿出, 最 后在一侧将荷包线的两个端头打结,这至少需要相当于两倍的荷包钳 长度才能完成手术的操作 (针需要很大的操作空间), 然而对于直肠 切除或食道切除等位置受局限的手术部位来说,使用此种荷包钳来打 荷包无法完成手术或存在极大的手术风险,由于没有很好的手术视野, 又是手工缝针, ί艮容易伤到相邻的其他组织器官,存在巨大的手术风 险。 另一种是直线型缝钉式自动荷包钳,手术时先把组织用钳口夹住, 然后锁紧槽口,人体组织会自然的被夹紧并有一部分组织挤入槽口空 隙内。 同时缝钉将荷包线压在组织上, 此时松开槽口, 提拉器械, 荷 包线会沿着缝钉所钉出的轨道随器械提出一段长度(器械内藏一个线 仓, 可以存储 600mm长的缝合线) 然后打荷包。 此器械对于直肠切除 或食道切除等位置受局限的手术部位来说,存在很大缺点: 首先荷包 线只能沿着器官组织横切面提拉,这样就要求必须有合适的操作空间, 否则很容易斜向受力使缝钉与组织脱离, 导致打荷包失败, 而对位置 受限的部位来说, 恰恰不可能有合适的操作空间, 所以在此种部位做 手术风险极大; 其次, 因提拉力过大, 可能导致缝钉落入人体内, 因 位置局限且缝钉很小, 不容易发现掉落的缝钉, 最终可能导致缝钉留 在人体体内, 可能给病人带来生命威胁。 由此可见, 现有荷包钳存在明显的缺陷和不足, 如何创设一种能 在手术狭窄部位自动、 方便、可靠打荷包的荷包缝合器实属当前重要 的研发课题之一。 发明内容 本发明要解决的技术问题是提供一种可自动打荷包的圆形荷包 钳, 使其对于直肠切除或食道切除等位置受局限部位进行手术时, 能 够自动、 方便、 可靠地进行打荷包, 从而克服现有技术的不足。 为解决上述技术问题, 本发明一种可自动打荷包的圓形荷包钳, 包括钳体、 缝针组件和缝针驱动装置, 其中: 钳体头部内设有环形缝 针滑槽; 缝针组件可滑动的安装在所述的环形缝针滑槽内; 缝针驱动 装置与钳体可转动连接,缝针驱动装置的头部带动缝针组件绕环形缝 针滑槽移动。 作为本发明的进一步改进, 所述的缝针驱动装置包括旋转轴、驱 动旋钮、 传动齿轮、 摆臂齿轮和摆臂, 其中: 旋转轴可转动的安装在 钳体内; 驱动旋钮与旋转轴尾端固定连接; 传动齿轮与旋转轴的前端 固定连接; 摆臂齿轮与旋转轴不同轴, 并与传动齿轮啮合; 摆臂一端 与摆臂齿轮固定连接, 另一端与缝针组件固定连接。 所述的缝针组件包括滑块以及与滑块固定连接的内、 外弧形缝 针, 所述的缝针驱动装置的摆臂与缝针组件的滑块固定连接。 所述的钳体尾端还安装有保险装置, 该保险装置包括保险旋钮、 与保险旋钮固定连接的保险轴、 以及固定在保险轴上的锁紧块, 所述 的缝针驱动装置的尾部设有与锁紧块对应的卡槽。 所述的卡槽设置在缝针驱动装置的旋转轴上。
所述的旋转轴尾部横截面为多半圓形,所述的卡槽即为该横截面 的缺口。 所述的摆臂齿轮的两端设有轴向定位凸台。 所述的钳体包括固定钳体和活动钳体, 其中: 固定钳体包括固定 手柄和固定头部, 固定头部一侧设有弧形齿状边缘, 缝针驱动装置即 安装在该固定钳体内; 活动钳体包括把手部、 叉形部和弧形头部, 弧 形头部设有可与固定头部闭合的齿状结构; 固定钳体的固定手柄穿过 活动钳体的叉形部, 并通过固定销可转动连接; 所述的缝针驱动装置 的摆臂齿轮与活动钳体的叉形部位置对应。 所述的固定钳体的固定手柄和活动钳体的手把部对应设有钳口 锁紧挂钩。 采用上述设计后, 本发明与现有技术相比有以下有益效果: 该圆 形自动荷包钳适用于直肠切除或食道切除等位置受局限的狭窄手术 部位, 能够保证荷包处组织适量, 自动、 方便、 可靠进行打荷包。 下面通过附图和实施例,对本发明的技术方案做进一步的详细描 述。 附图说明 上述仅是本发明技术方案的概述, 为了能够更清楚了解本发明, 以下结合附图与具体实施方式对本发明作进一步的详细说明。

其中, 缝针驱动装置 4与钳体可转动连接, 缝针驱动装置 4的头 部带动缝针组件 3绕环形缝针滑槽移动。 具体来说, 请配合参阅图 7 所示, 缝针驱动装置 4 包括旋转轴 41、 驱动旋鈕 42、 传动齿轮 43、 摆臂齿轮 44和摆臂 45。 其中, 旋 转轴 41位于缝针驱动装置 4的中部, 可转动的安装在钳体内, 驱动 旋钮 42与旋转轴 41的尾部固定连接,传动齿轮 43与旋转轴 41的头 部固定连接, 摆臂齿轮 44与旋转轴 41不同轴, 并与传动齿轮 43啮 合,摆臂 45—端与摆臂齿轮 44固定连接, 另一端与缝针组件 3固定 连接。 较佳的, 摆臂齿轮 44靠两端的凸台轴向定位, 摆臂 45—端通过 螺栓与摆臂齿轮 44相连, 另一端通过螺栓与缝针组件 3连接。 当驱 动旋鈕 42转动时, 扭转力通过旋转轴 41、 传动齿轮 43、 摆臂齿轮 44传导到摆臂 45 , 摆臂 45带动缝针在环形封装滑槽中运动。 钳体可由固定钳体 1和活动钳体 2组成。 请配合参阅图 3所示, 固定钳体 1包括固定手柄 11和固定头部, 固定头部一侧设有弧形齿 状边缘,缝针驱动装置 4的旋转轴即可转动的安装在固定手柄 11内。 具体来说, 固定头部主要由固定钳体前片 12、 固定钳体后片 13、 顶盖板 14、 头部底板 15和头部挡板 16通过螺栓组装而成。 其中, 固定钳体后片 13和固定钳体前片 12的一侧为弧形齿状边缘,齿状结 构对应的角度不大于 180° , 固定钳体后片 13和固定钳体前片 12之 间形成环形缝针滑槽。 顶盖板 14为扇形, 安装在固定钳体前片 12前 表面, 与非齿状结构的部分对应。 头部底板 15为半圆或多半圆形, 安装在固定钳体后片 13的后侧, 与非齿状结构的部分对应。 头部挡 板 16安装在固定钳体后片 13的一侧, 与头部底板 15配合, 封闭固 定钳体后片 13非齿状部分的后侧空间。 此外, 在固定钳体 1的固定头部内 (例如固定钳体后片 13上), 在齿状结构的一端处设有线槽 17和顶针挡板 18, 线槽 17外侧被线 槽挡板 19封闭, 线槽 17内容置有可吸收的缝线, 线槽挡板 19通过 插槽插接在固定头部后片 1 3上。 请配合参阅图 4所示, 活动钳体 2包括把手部 21、 叉形部 22和 弧形头部 23, 其中, 弧形头部 23与固定钳体 1的固定头部的齿状边 缘对应, 并设有可与固定头部闭合的齿状结构, 叉形部 22与弧形头 部 23的两端固定连接。 具体来说, 把手部 21外侧可利用过盈配合套有柄套 24。 活动钳 体 2的弧形头部 23也可由前、 后片通过螺栓组装而成, 前、 后片之 间设有弧形缝针滑槽。叉形部中空结构有足够的空间, 以便手术时剪 刀剪断组织。 较佳的, 固定钳体前片 12与固定钳体后片 13之间、 固定钳体后 片 13与头部底板 15之间、 以及活动钳体 2弧形头部 23的前、 后片 之间均设有对应的弧形凸起和凹槽, 以保证连接位置的精度, 提高组 装效率。 固定钳体 1的固定手柄 11穿过活动钳体 2的叉形部 22 , 并通过 固定销 25可转动连接,还可在固定钳体 1的固定手柄 11和活动钳体 2的手把部 21对应设有钳口锁紧挂钩 26。钳口锁紧挂钩 26可为如图 4所示的 L型倒钩, 下压活动钳体 2的^ ^手部 21时, 两 L型倒钩相 互钩在一起,固定钳体 1的固定头部和活动钳体 2的弧形头部闭合锁 紧。 如果要松开活动钳体, 必须保证缝针回到初始位置, 然后在活动 钳体 2的把手部 21上施加一定的侧向力, L型倒钩相互脱开, 钳口 得以张开。 缝针驱动装置 4的摆臂齿轮 44的设置位置即与叉形部 22对应。 通过摆臂齿轮 44和传动齿轮 43的配合可以使旋转轴 41的轴线相对 于摆臂齿轮 44的轴线偏移, 从而使固定钳体 1与活动钳体 2之间的 距离加大, 活动钳体 2的弧形设计和齿轮轴线的偏离, 为手术时剪刀 剪断组织提供空间。在手术过程中, 当荷包钳进针及带线过程完成后, 需要剪断组织松开钳口, 此时医生可以拿剪刀从活动钳体 2的侧面及 正面剪断组织, 因此, 本轴线偏移的设计十分必要的。
请配合参阅图 5所示,固定钳体 1的固定头部和活动钳体 2的弧 形头部闭合呈整圓形, 该圆形的直径在 30-80瞧之间, 闭合后的荷包 钳的头部内具有完整的环形缝针滑槽,缝针组件 3即安装在环形缝 4† 滑槽内。 请配合参阅图 6所示, 缝针组件 3包括针座滑块 31以及一端插 入针座滑块 31并通过螺钉锁定的内缝针 32和外缝针 33, 针座滑块 31 为一圓弧块, 内、 外缝针的针体均为弧形, 针体截面为 Q. 6-3mm 的圓形, 头部为锥形并设有倒钩。 对应的, 请配合参阅图 5、 图 6所示, 环形缝针滑槽在与齿状结 构对应段为两条较细且相互平行的内、 外缝针滑槽,在非齿状结构对 应段则为一条较宽的滑块滑槽。 而线槽 17 内也应容置两条缝线, 缝 线端头探出顶针挡板 18, 并分别与内针套 34、 外针套 35连接。 内、 外针套内部中空, 与内、 外针体的截面直径相当, 边缘有倒角, 为倒 锥形, 头部开槽, 以便针头顺利插入。 连接针头与针体之间还可设有 过渡段, 在过渡段处针头形成明显的凸台以便挂住针套头部开槽, 针 头旋转到位后, 会挤入针套中, 钩紧针套, 使针套能够被带回。 缝针的初始位置位于荷包钳头部齿状结构的一端,针套位于另一 端, 针套尾部连接有缝线且靠在顶针挡板 18上, 缝线通过设置在固 定钳体后片 1 3的孔道缠绕在线槽 17中。缝针沿环形缝针滑槽穿过夹 在固定钳体 1和活动钳体 2之间的组织, 移动到针套处, 针头插入针 套, 之后反向转动缝针, 缝针的倒钩把针套带回, 使缝线穿过组织。 此外, 请配合参阅图 8、 图 9所示, 本发明还可在固定手柄 1的 尾端安装保险装置 5, 用于保证各部件击发前处于初始状态。 该保险 装置 5包括保险旋钮 51、 与保险旋钮 51固定连接的保险轴 52、 以及 固定在保险轴 52上的锁紧块 53, 缝针驱动装置 4的尾部对应设有与 锁紧块 53对应的卡槽。 进一步来说, 可将缝线驱动装置的旋转轴 41尾部的横截面设计 为多半圓形, 卡槽即为该横截面的缺口, 保险装置的锁紧块 53采用 立方体结构即可与该缺口较好的卡死。 此外, 还可在保险旋钮 51内侧固定一定位销 54, 与固定手柄 11 上的凹槽配合, 可使锁紧块 53准确快速的卡入卡槽内。 当保险装置处于锁定状态时, 锁紧块 53压紧旋转轴 41的卡槽, 使得通过驱动旋钮 42不能转动旋转轴 41, 从而使缝针无法运动, 起 到保险作用。 当使用荷包钳时, 旋转保险旋钮 51使锁紧块 53与旋转轴 41的 卡槽分离, 此时, 解除锁定状态, 转动驱动旋钮 42, 旋转轴 41可以 随着驱动旋钮 42转动, 从而带动缝针运动, 进行打荷包操作。 使用时, 先将钳口锁紧挂钩 26打开, 将需要打荷包的肠道部位 放入钳口 闭合活动钳体 2的把手部 21,使钳口锁紧挂钩 26卡住, 保持荷包钳闭合锁紧状态, 使肠道组织保持压缩状态。 拨动保险旋钮 51 , 打开保险, 使驱动旋钮 42可以转动。 当驱动 旋钮 42旋转约二分之一圆周时, 扭转力通过刚性连接的缝针驱动装 置 4传递到针座滑块 31 , 从而推动针座滑块 31上的缝针 32、 33在 环形缝针滑槽内运动, 缝针刺穿钳口间隙内的人体组织, 当针尖旋转 到滑槽的另一端的针套处时, 针头插入针套并通过倒钩卡住, 同时针 头会推动针套靠在顶针挡板 18上, 驱动旋钮 42无法进一步转动, 以 保证针头与针套的连接到位。 之后, 反向旋转驱动旋钮 42, 缝针将针套带回, 经过钳口闭合 的部分, 使针套尾部的缝线穿过人体组织。在针套被缝针拉到钳口另 一边的过程中, 针套及其后部连接的缝线穿过被加紧的人体组织, 两 根荷包线分别从组织的两侧穿过,由于钳口的齿形作用使荷包线一段 一段穿过组织。 当旋转驱动旋钮 42约二分之一圆周后, 手部有挂钩 卡住的震感, 这时缝针组件 3回到初始位置。 最后, 打开钳口锁紧挂钩 26, 拉扯荷包钳, 使缝钱放出来, 当 放出的线足够用时, 剪断两侧缝线, 取出荷包钳, 两侧拉伸缝线, 调 整位置, 将吻合器的头部置于组织内, 拉紧两侧缝线, 将缝线系在圆 形吻合器头部的中心杆上手动系紧, 打荷包完成。 本圆形自动荷包钳适用于直肠切除或食道切除等位置受局限的 狭窄手术部位, 也可用于操作空间宽敞的其它部位的手术。
以上所述,仅是本发明的较佳实施例而已, 并非对本发明作任何 形式上的限制,本领域技术人员利用上述揭示的技术内容做出些许简 单修改、 等同变化或修饰, 均落在本发明的保护范围内。
