技术领域
本发明涉及手术机器人送丝装置, 属于医疗设备领域。 背景技术
随着我国人民生活水平的不断提高,人们的饮食结构在不断地发生变 化。其中心脑血管等血管类型疾病的发病率不断攀升, 成为除肿瘤以外威 胁人类生命安全的主要杀手。而造成血管疾病的主要原因是血管硬化或血 管粥样硬化。 目前治疗心脑血管疾病的主要方法是通过手术。微创血管介 入手术比传统的手术有很多优点。传统心脏手术最常用的方法是开胸后在 体外循环下完成。 因手术中需要劈开胸骨, 病人将承受巨大创伤, 胸前会 留下长达 20厘米的疤痕, 造成生理和心理负担。 微创血管介入手术可以 避免病人长期暴露在 X射线下, 减小辐射, 并且只需在病人身上开启很 小的切口。 微创技术因其切口小、 创伤轻、 痛苦少、 恢复快而受到患者和 临床医生的欢迎。
传统的微创血管手术方法是在 X射线影像或其他灰度图像的监控和 引导下, 由医生手工直接完成导管或者导丝, 导引导丝, 安全球囊及支架 的递送过程。但由于现有的导管前段的弯曲半径固定以及人体内血管存在 弯曲狭长, 不规则, 分支多等特点, 使这种方法技术性强, 风险性高; 同 时现有的微创血管介入手术机器人送管机构虽然有自主送导管和送导丝 的功能, 但是还不具有自主送支架和球囊的功能, 在支架和球囊送入和抽 出人体时, 由于输送球囊和支架的导引导丝材质较软, 夹持球囊或支架递 送的时候, 不可避免的会触碰到内部的导引导丝, 从而使其发生弯曲或位 置变动, 但是在整个的递送过程中为保证球囊和支架递送位置的精确, 需 要保证导引导丝的位置不能变动,因此在没有机器人辅助手术或者辅助手 术的机器人不具备压丝功能的情况下,手术过程中仍旧需要医生压住支架 和球囊的导引导丝, 这均要求医生培训时间长, 同时手术过程操作复杂, 手术时间长, 医生易于疲劳和人工操作不稳定等因素会增加手术的风险。 发明内容

球囊压丝器主要分为压丝轮组件和压丝轮过渡架。球囊压丝器的主要 作用是: 在手术最后的过程中, 需要递送球囊 /支架, 而球囊 /支架的递送 是靠导引导丝来引导的, 导引导丝已经穿入人体的毛细血管中; 而现今大 多数的送丝装置并不具备在球囊 /支架递送过程中压紧导引导丝的功能, 需要人工压丝, 而人工压丝不仅需要对医生进行大量培训, 而且增加医生 在手术过程中的疲劳程度,但是人工压丝并不能保证在手术过程中压丝的 精确性, 而压丝的精确度直接影响到手术的成功; 一旦在手术过程中压丝 不到位, 将会使导引导丝在人体毛细血管中发生轴向移动, 从而不能将球 囊 /支架正确引导到需要的位置, 这将严重影响到手术的成功。 而球囊压 丝器就是在递送球囊 /支架过程中, 保证始终压紧导引导丝, 使不会发生 任何的轴向移动, 保证导引导丝的导引功能, 从而成功的保证了手术的成 功率。其中压丝轮组件包括压丝轮摆动体, 压丝轮高低摆动架, 压丝轮销 轴, 回转架板, 扭簧销轴与扭簧; 其中压丝轮销轴将压丝轮高低摆动架与 压丝轮摆动体相连, 压丝轮高低摆动架与回转架板通过扭簧销轴连接, 扭 簧装在扭簧销轴上,回转架板通过其上的螺纹杆与压丝轮过渡架螺纹孔配 合连接, 并且回转架板可以相对压丝轮过渡架转动。 图 12表示压丝轮组 件处于压丝状态, 不需要压丝时, 按动压丝轮组件上的压丝轮高低摆动架 装有弹簧侧的末端, 将压丝轮组件旋转 180度, 压丝轮组件到达图 13所 示的闲置状态。压丝轮摆动体的压丝轮在压丝过程中不仅可以绕其转动轴 线转动,还可随压丝轮摆动体绕压丝轮销轴转动,形成压丝轮的万向转动, 保证了压丝轮在压丝过程中始终能够压紧导引导丝,不会因为压丝板的细 微变形而影响球囊压丝器的压丝功能。 压丝轮摆动体包括紧钉座, 球座, 压丝轮,压丝轮架,钢球和槽平端紧定螺钉。钢球起轴承作用,方便清洗, 并当导引导丝通过压丝轮时可以使压丝轮旋转, 实现压丝功能。
移动指夹持器包括夹持器定指过渡架, 夹持器定指, 夹持器动指过渡 架, 夹持器动指, 夹持器动板和夹持器摆动板, 夹持弹簧。 其中夹持器动 指过渡架通过螺钉连接固定在夹持器动板上,夹持器动指通过螺钉连接固 定在夹持器动指过渡架上;夹持器定指过渡架通过螺钉连接固定在夹持器 摆动板上, 夹持器定指通过螺钉连接固定在夹持器定指过渡架上。其中夹 持器动板与夹持器摆动板滑动连接, 通过夹持弹簧实现夹紧。并且夹持器 动板与移动指机架的凸轮接触, 当移动指开合传动杆带动凸轮转动时, 凸 轮推动夹持器动板横向移动, 此时夹持弹簧被拉伸, 移动指夹持器处于张 开状态。 当移动指开合传动杆反向运动时, 带动凸轮反向转动, 此时凸轮 对夹持器动板不起作用, 但夹持弹簧要恢复原状态, 进而实现了移动指夹 持器的夹紧。夹持器摆动板上有一销轴孔, 转动销轴通过该销轴孔将夹持 器摆动板与移动指机架相连, 并且夹持器摆动板可绕转动销轴转动。移动 指架体上装有压力传感器,为了保持夹持器摆动板始终和压力传感器相接 触并有一定的预紧力, 在移动指架体的转动销轴的另一侧安装有弹簧, 移 动指部件在递送导管、 导丝、 支架、 球囊的过程中若遇到血管堵塞或者分 叉的部分, 移动指夹持器受到的阻力将增加, 移动指夹持器将会绕着转动 销轴发生轻微转动,进而通过夹持器摆动板向压力传感器的弹性触头施加 压力, 从而使压力传感器产生信号变化, 该信号可用于虚拟力反馈控制, 使操作医生具有临场力感觉, 大大提高了操作的安全性。

所述具有球囊 /支架递送功能的微创血管介入手术送管送丝装置的 Y 阀固定架由钳口架,托架和旋转销柄构成。主要作用在于固定手术用 Y阀, 在不需要 Υ阀时, Υ阀固定架可以旋转 90度, 使其自身高度低于导丝递 送平面,避免影响导丝递送。钳口架通过内六角圆柱头螺钉固定在托架上; 旋转销柄与穿过托架前段带有螺纹的旋转销轴连接,其中旋转销轴在穿过 托架孔的尺寸变换处装有笔芯弹簧,它的主要作用是当旋转销柄带动旋转 销轴实现轴向移动时, 笔芯弹簧被压缩, 使旋转销轴与机架组件脱离, 此 时将旋转托架旋转 90度后, 放松旋转销柄, 笔芯弹簧复位, 旋转销轴再 次与机架组件实现配合。钳口架是由带有螺纹的旋转手轮实现动架与定架 的运动, 进而实现钳口架的开合; 止推销使手轮实现定位旋转。

如图 12至图 21所示, 移动指部件 4包括轴向进给的移动指夹持器 75和保证支架与球囊能够顺利抽出与送入人体毛细血管的球囊压丝器 74 以及移动指机架 73及导轨 76四大部分; 其中移动指夹持器 75是通过转 动销轴 84固定在移动指机架 73上, 球囊压丝器 74是通过螺钉固定在移 动指机架 73上。 移动指机架 73包括移动导板 88, 移动指架体 82, 凸轮 87和凸轮架 86。 移动导板 88是通过螺钉连接固定在移动指架体 82上, 移动导板 88可以沿导轨 76滑动, 导轨 76通过螺钉连接固定在机架组件 8上; 凸轮 87装在凸轮架 86上, 凸轮架 86与移动指架体 82是通过螺钉 连接固定的。移动指动力丝杠 11穿过移动指架体 82上的光孔与驱动螺母 80实现螺纹传动, 驱动螺母 80与移动指架体 82四周均留有一定空间, 方便驱动螺母 80的拆装; 防转销轴 81的一端与移动指架体 82的螺纹孔 实现螺纹配合, 另一端穿过驱动螺母 80的一侧, 防止移动指动力丝杠 11 与驱动螺母 80在动力传递过程中驱动螺母 80自身转动,使移动指动力丝 杠 11顺利推动移动指架体 82前后移动,进而实现移动指部件 4在送丝过 程中的轴向进给。 在移动指架体 82上装有永久磁铁 89, 当移动指部件 4 在轴向进给到达导轨 76的极限位置时,导轨上的干簧管 77感应到永久磁 铁 89, 并发出反馈信号传送到计算机, 计算机将处理过的信号来控制电 机四 19。带动移动指机架 73上的凸轮 87运动的是移动指开合传动杆 10, 此凸轮 87的运动实现了移动指夹持器 75的张开与闭合。 球囊压丝器 74 主要分为压丝轮组件 78和压丝轮过渡架 79。 球囊压丝器的主要作用是: 在手术最后的过程中, 需要递送球囊 /支架, 而球囊 /支架的递送是靠导引 导丝来引导的, 导引导丝已经穿入人体的毛细血管中; 而现今大多数的送 丝装置并不具备在球囊 /支架递送过程中压紧导引导丝的功能, 需要人工 压丝, 而人工压丝不仅需要对医生进行大量培训, 而且增加医生在手术过 程中的疲劳程度, 但是人工压丝并不能保证在手术过程中压丝的精确性, 而压丝的精确度直接影响到手术的成功; 一旦在手术过程中压丝不到位, 将会使导弓 1导丝在人体毛细血管中发生轴向移动, 从而不能将球囊 /支架 正确引导到需要的位置, 这将严重影响到手术的成功。而球囊压丝器就是 在递送球囊 /支架过程中, 保证始终压紧导引导丝, 使不会发生任何的轴 向移动, 保证导引导丝的导引功能, 从而成功的保证了手术的成功率。其 中压丝轮组件 78包括压丝轮摆动体 93, 压丝轮高低摆动架 91, 压丝轮销 轴 94, 回转架板 90, 扭簧销轴 95与扭簧 92; 其中压丝轮销轴 94将压丝 轮高低摆动架 91与压丝轮摆动体 93相连, 压丝轮高低摆动架 91与回转 架板 90通过扭簧销轴 95连接, 扭簧 92装在扭簧销轴 95上, 回转架板 90通过其上的螺纹杆 96与压丝轮过渡架 79螺纹孔配合连接, 并且回转 架板 90可以绕螺纹杆 96相对压丝轮过渡架 79发生水平面转动。图 12表 示压丝轮组件 78处于压丝状态, 不需要压丝时, 按动压丝轮组件 78上的 压丝轮高低摆动架 91装有扭簧 92侧的末端, 将压丝轮组件 78旋转 180 度, 压丝轮组件到达图 13所示的闲置状态。 压丝轮摆动体 93 的压丝轮 97在压丝过程中不仅可以绕其转动轴线转动, 还可随压丝轮摆动体 93绕 压丝轮销轴 94转动(其位置关系如图 18所示), 形成压丝轮 97的万向转 动, 保证了压丝轮 97在压丝过程中始终能够压紧导引导丝 111, 不会因 为压丝板 3的细微变形而影响球囊压丝器 74的压丝功能。 压丝轮摆动体 93包括紧钉座 99, 球座 102, 压丝轮 97, 压丝轮架 98, 钢球 101和槽平 端紧定螺钉 100。 钢球 101起轴承作用, 方便清洗, 并当导引导丝 111通 过压丝轮 97时可以使压丝轮 97滚动和旋转, 实现压丝功能。移动指夹持 器 75包括夹持器定指过渡架 106, 夹持器定指 105, 夹持器动指过渡架 103, 夹持器动指 104, 夹持器动板 109和夹持器摆动板 107, 夹持弹簧 108。其中夹持器动指过渡架 103通过螺钉连接固定在夹持器动板 109上, 夹持器动指 104通过螺钉连接固定在夹持器动指过渡架 103上;夹持器定 指过渡架 106通过螺钉连接固定在夹持器摆动板 107上, 夹持器定指 105 通过螺钉连接固定在夹持器定指过渡架 106上。其中夹持器动板 109与夹 持器摆动板 107滑动连接, 通过夹持弹簧 108实现夹紧。并且夹持器动板 109与移动指机架 73的凸轮 87接触, 当移动指开合传动杆 10带动凸轮 87转动时, 凸轮 87推动夹持器动板 109横向移动, 此时夹持弹簧 108被 拉伸, 移动指夹持器 75处于张开状态。 当移动指开合传动杆 10反向运动 时, 带动凸轮 87反向转动, 此时凸轮 87对夹持器动板 109不起作用, 但 夹持弹簧 108要恢复原状态, 进而实现了移动指夹持器 75的夹紧。 夹持 器摆动板 107上有一销轴孔, 转动销轴 84通过该销轴孔将夹持器摆动板 107与移动指机架 73相连,并且夹持器摆动板 107可绕转动销轴 84转动。 移动指架体 82上装有压力传感器 83, 为了保持夹持器摆动板 107始终和 压力传感器 83接触并有一定的预紧力, 在移动指架体 82的转动销轴 84 的另一侧安装有弹簧 85, 移动指部件 4在递送导管、 导丝、 支架与球囊 110的过程中若遇到血管堵塞或者分叉的部分, 移动指夹持器 75受到的 阻力将增加, 移动指夹持器 75将会绕着转动销轴 84发生轻微转动, 进而 通过夹持器摆动板 107向压力传感器 83的弹性触头施加压力, 从而使压 力传感器 83信号变化, 该信号可用于虚拟力反馈控制, 使操作医生具有 临场力感觉, 大大提高了操作的安全性。移动指部件 4能够实现在送入与 抽出球囊与支架 110时按压住导引导丝 111, 使其位置不发生变动, 保证 后续的导引功能。实现方式是夹持指动指 104和夹持指定指 105是采用平 面与平面的接触方式闭合来夹紧的,并且鉴于该导引导丝 111的直径远远 比球囊与支架 110的直径小,因此在送入和抽出球囊与支架 110的过程中, 虽然移动夹持器 75处于夹紧状态, 球囊或支架 110与导引导丝 111同时 处于夹持指动指 104和夹持指定指 105之间,但其实被夹紧的只有球囊或 支架 110, 导引导丝 111与移动指夹持器 75处于脱离状态, 在球囊或支 架 110送入和抽出毛细血管时, 导引导丝 111不会发生轴向移动, 此时球 囊压丝器 74将导引导丝 111压紧, 因此在球囊与支架 110送入和抽出毛 细血管时, 导引导丝 111不会发生弯曲, 可以使球囊与支架 110顺利的送 入和抽出毛细血管。

如图 24至图 28所示, Y阀固定架 1主要由钳口架 120, 托架 121, 旋转销轴 122和旋转销柄 123构成。 Y阀固定架 1与机架组件 8的前骨架 9是通过双头螺柱连接固定的。钳口架 120通过内六角圆柱头螺钉固定在 托架 121上, 钳口架 120是由定架体 125, 动架体 127, 手轮 129, 止推 销 128, 孔堵 126构成的; 动架两端分别悍接方卡口与六方卡口的一半构 成动架体 127, 定架两端分别悍接方卡口与六方卡口的一半构成定架体 125, 定架体 125与动架体 127是通过手轮 129连接在一起的, 其中动架 体 127与手轮 129是通过螺纹固定连接的, 这样在旋转手轮 129时, 可以 实现动架体 127与定架体 125的靠近与远离,进而实现钳口架 120的夹紧 与放松, 止推销 128使手轮 129实现定位旋转 ; 旋转销柄 123通过前段 带有螺纹的旋转销轴 122与托架 121连接, 托架 121的后端打有螺纹孔, 通过双头螺柱 130与机架组件 8的前骨架 9固定;其中旋转销轴 122在穿 过托架孔的尺寸变换处装有笔芯弹簧 124, 它的主要作用是当旋转销柄 123带动旋转销轴 122实现轴向移动时, 笔芯弹簧 124被压缩, 使旋转销 轴 122与机架组件 8脱离, 此时将托架 121旋转 90度后, 放松旋转销柄 123, 笔芯弹簧 124复位, 旋转销轴 122再次与机架组件 8的前骨架 9实 现配合, 此时 Y阀固定架 1处于闲置状态, 如图 25所示。 用同样的方法 可以使 Y阀固定架 1处于工作状态,因为 Y阀固定架 1与机架组件 8的前 骨架 9是通过双头螺柱 130连接的,同时与 Y阀固定架 1相连的机架组件 8的前骨架 9上打有以双头螺柱 130为中心的水平与垂直的两个孔, 主要 是为了与 Y阀固定架 1的旋转销轴 97配合, 其结构如图 24所示。
如图 1至图 28所示, 在整个装置中, 动力传动的流程为: 电机一 26 通过传动箱部件 6将运动传递给传动杆一 39, 传动杆一 39带动拨叉 59 进而实现了旋转指部件 5的张开与闭合的动作; 电机二 25通过传动箱部 件 6将运动传递给传动杆二 40, 传动杆二 40将动力传递给固定指部件开 合齿轮组的主动轮 47, 通过与固定指开合介轮 46的啮合, 将动力传递到 固定指开合从动轮 45上, 通过万向节 14将动力带到开合指开合传动轴 13上, 进而再次通过万向节 14将动力传递到实现固定指开合动作的固定 指齿轮 112上,通过固定指齿轮 112与固定指座体 114的齿条的啮合最终 实现了固定指部件 2的张开与闭合的动作; 电机三 24通过传动箱部件 6 将运动传递给传动杆三 38, 传动杆三 38直接传递给旋转指带动主动带轮 组件 70,通过齿形同歩带 63带动了大导向轮组件 67,张紧带轮组件 64, 小带轮组件 65的运动, 进而实现了旋转指部件 5的旋转动作, 为搓丝做 准备; 电机四 19通过传动箱部件 6将动力传到传动杆四 37上, 进而到移 动指部件移动齿轮组的移动主动轮 49上, 通过啮合关系将动力传到移动 指部件移动齿轮组的移动从动轮 44上,移动从动轮 44通过带动移动指动 力丝杠 11的运动, 进而实现了移动指部件 4的前进与后退; 电机五 20通 过传动箱部件 6将动力传到传动杆五 36, 传动杆五 36将动力传到移动指 部件开合齿轮组的移动指开合主动轮 51上,通过移动指开合介轮 50将动 力传到移动指开合从动轮 43上,移动指开合从动轮 43带动移动指开合传 动杆 10通过凸轮 87作用实现了移动指部件 4的张开与闭合的动作。
