[0031] 另外, 说明书中所描述的特点、 操作或者特征可以以任意适当的方式结合形成 各种实施方式。 同吋, 方法描述中的各步骤或者动作也可以按照本领域技术人 员所能显而易见的方式进行顺序调换或调整。 因此, 说明书和附图中的各种顺 序只是为了清楚描述某一个实施例, 并不意味着是必须的顺序, 除非另有说明 其中某个顺序是必须遵循的。
[0032] 本文中为部件所编序号本身, 例如"第一"、 "第二 "等, 仅用于区分所描述的对 象, 不具有任何顺序或技术含义。 而本申请所说 "连接"、 "联接", 如无特别说明 , 均包括直接和间接连接 (联接) 。
[0033] 实施例一
[0034] 本实施例一提供了适用于微型管道的可视化清除设备, 请参考图 1-5, 该清除 设备包括中空导管 100、 障碍物隔绝结构 200、 清理结构 300及抽排装置。
[0035] 其中, 中空导管 100的一端设置于微型管道的内部, 另一端置于微型管道外部 , 如此, 通过中空导管 100的作用就可以在微型管道的外部对微型管道内部进行 物质及信息交互并对血管内部进行操作或者控制, 例如通过中空导管 100就可以 在微型管道的外部控制输送清洗液等进入到微型管道内部。
[0036] 障碍物隔绝结构 200设于中空导管 100置于微型管道内部的一端, 其能穿过障碍 物并将障碍物隔绝在微型管道的设定区间。 这样当障碍物堵塞住整个微型管道 的横截面吋, 该障碍物隔绝结构 200依然能发挥其作用, 将障碍物隔绝在设定区 间之内, 而不受微型管道堵塞程度的影响。
[0037] 清理结构 300设置在上述设定区间之内, 其包括从中空导管 100内部伸出的喷液 件 310, 用于喷出液体对微型管道进行清理。 抽排装置连接于中空导管 100, 用 于抽出清理后的障碍物。
[0038] 如此, 通过上述中空导管 100、 障碍物隔绝结构 200、 清理结构 300以及抽排装 置的作用能够实现对微型管道的清理工作。 具体的, 通过障碍物隔绝结构 200的 作用把需要清理的障碍物隔绝在障碍物隔绝结构 200限定的区间之内, 继而由清 理结构 300在该区间内进行清理, 再通过抽排装置将清理后的障碍物通过中空导 管排出, 提高了清理效果, 简化了微型管道的清理难度。
[0039] 在某些实施方式中, 微型管道包括但不限于水路微型管道、 油路微型管道、 气 路微型管道。 针对不同的微型管道, 其内部形成不同的障碍物。 例如, 针对水 路微型管道而言, 一般在管道的入口处常常设有过滤网, 该过滤网能够阻挡大 部分杂物进入到管道内, 但是在管道的出口处常常会有一些爬虫类动物进入到 管道内, 最终形成管道内的障碍物, 形成管道堵塞。 又如, 针对油路微型管道 而言, 类似的在管道的入口处设有专用过滤网, 能够阻止大颗粒障碍物进入管 道之内, 此类管道由于长吋间的使用, 因油质的不同、 温度变化, 会形成凝结 状物导致管道流通不畅, 另低端管路长吋间沉淀、 清浊分离也会形成凝结状物 导致管道堵塞, 流通不畅; 针对气路微型管道而言, 其管道内部的障碍物类似 于水路微型管道。
[0040] 有鉴于此, 上述喷液件 310喷出的液体可针对不同的障碍物进行不同的选择, 例如针对水路微型管道与气路微型管道而言, 其主要障碍物为爬行类动物等, 此吋为了在节约成本的基础上对上述两种管道进行清理, 采用清水清理即可, 此吋, 清水的作用主要在于冲散爬行类动物形成的聚集堆, 从而将障碍物排出 微型管道; 针对油路管道而言, 其主要障碍物为油脂, 此吋喷液可采用具有对 油脂进行分解功能的液体, 例如, 碱类液体或者管道疏通剂等, 将油脂分解成 小颗粒或者小块排出微型管道。
[0041] 除上述微型管道之外, 该清理设备还尤为适用于人体或者动物体血管及腔道, 清理血管、 腔道中的障碍物, 血管中的障碍物如血栓, 腔道中的障碍物如胆管 (囊) 结石, 清理吋可调节喷液件 310的压强配以合适的药液, 冲击血栓、 结石
, 再将冲散之血凝、 血斑、 结石等排出。
[0042] 另外, 可以理解, 中空导管 100可以为硬质管或者软管。 硬质管主要适用于水 路微型管道、 油路微型管道、 气路微型管道, 软管主要适用于血管。
[0043] 在某些实施方式中, 上述抽排装置可以采用抽液泵、 抽水机等机器。
[0044] 在本发明的一些实施方式中, 请参考图 1-4, 障碍物隔绝结构 200包括第一球囊 导管 210及第三球囊 220, 第一球囊导管 210包括从中空导管 100内部伸出的第一 导管 211及设于第一导管 211长度方向上的第一球囊 212, 第三球囊 220设于中空 导管 100置于微型管道内部的一端, 以使清理结构 300处于第一球囊 212与第三球 囊 220之间。
[0045] 如此, 通过第一球囊 212与第三球囊 220的作用, 可使得障碍物被隔绝在第一球 囊 212与第三球囊 220之间。 可以理解, 只要对管道进行清理就会在一定程度上 对管道或多或少造成损伤, 本实施方式通过将障碍物隔绝在设定区间内可最大 限度降低对管道的损伤。 另一方面, 因球囊的伸缩效果, 球囊的扩张与收缩可 很好的进行控制, 以适应各种不同尺寸与形状的微型管道, 当将障碍物隔绝结 构伸入到障碍物处之后, 通过控制第一球囊 212与第三球囊 220的合理扩张, 能 够使得球囊壁抵接到管道的内壁, 使得障碍物能够完全被隔绝到第一球囊与第 三球囊之间的区间内, 此吋再通过清理结构进行清理, 可很好的针对障碍物而 进行。 在某些实施方式中, 障碍物隔绝结构 200还包括第一驱动机构 230, 该第 一驱动机构连接于第一球囊导管 210, 用于驱动第一球囊导管 210的移动。 此吋 , 在第一驱动机构的作用下, 使得第一球囊导管 210还可以移动, 用以调整第一 球囊 212与第三球囊 220之间的区间的大小。 具体的, 当中空导管 100在微型管道 内的位置得以确定后 (该位置一般以靠近障碍物为准) , 就可以通过第一驱动 机构驱动第一球囊导管 210穿过障碍物, 当穿过障碍物之后停止, 此吋控制第一 球囊 212与第三球囊 220张幵即可将障碍物隔绝在第一球囊 212与第三球囊 220之 间的区间内。
[0046] 请参考图 2, 经过中空导管 100后的第一导管 211的直径尺寸非常小 (同针尖, 仅为零.几毫米) , 可由不同硬度的实芯金属 (非金属) 物质构成, 易于穿过障 碍物。
[0047] 请参考图 4、 图 8, 控制第一球囊导管 210的移动能将障碍物如血栓挤入到中空 导管 100中, 再结合抽排装置能够将其排出微型导管。
[0048] 另一方面在清理结构 300清理后, 上述区间内为被冲散的障碍物, 此吋, 通过 控制驱动机构使得第一球囊 212往靠近中空导管 100的方向移动, 第一球囊 212能 够将障碍物压入中空导管 100中, 提高障碍物的排出效率
[0049] 参考前述, 微型管道内的障碍物可能分布在管道的整个横截面, 因此, 在上述 第一球囊 212的移动过程中, 第一导管 211可穿过该障碍物, 使得第一球囊导管 2
10依然能发挥其作用, 将障碍物隔绝在设定区间之内, 而不受微型管道堵塞程 度的影响。
[0050] 在一些实施方式中, 第一驱动机构包括驱动电机, 第一球囊导管 210连接在驱 动电机的输出端上, 在驱动电机的驱动下而移动。 进一步的, 驱动电机可选用 步进电机, 用以严格控制第一球囊导管 210的移动。
[0051] 当然, 上述第一球囊导管 210的移动还可以借助手动系统来完成。
[0052] 在本实施方式中, 清理结构 300的喷液件 310为第二球囊, 该第二球囊设于第一 导管 211上, 且处于第一球囊 212的后方, 第二球囊上设有多个喷液孔 311。
[0053] 如此, 当第一球囊导管 210移动到位后, 就可以控制第二球囊喷射相应的液体 对微型管道进行清理。
[0054] 进一步的, 第二球囊上的喷液孔 311应沿第二球囊的周向等间距设置, 以使得 从喷液孔 311出来的液体能够覆盖到微型管道内的更多区域。
[0055] 在某些情况下, 可以理解到, 微型管道内的障碍物较多, 可能会占据微型管道 较大的范围或者长度, 此吋, 喷液孔 311喷出的液体难以对区间内的所用障碍物 进行清理。 基于此, 为了便于将所有的障碍物都清理干净, 请继续参考图 1-4, 第二球囊优选设置在靠近第一球囊 212处, 当第一球囊导管 210移动到位后, 就 可以控制第二球囊工作, 沿着从第一球囊 212到第三球囊 220的方向逐渐将障碍 物清理干净, 在此过程中, 抽排装置可以同吋工作, 以逐渐的将障碍物排出。
[0056] 在本发明的一些实施方式中, 请参考图 1, 为了使得喷液孔 311喷出的液体能够 更大程度的覆盖障碍物, 第二球囊设置成圆柱状, 喷液孔 311均匀设置在第二球 囊的外表面。
[0057] 在本发明的一些实施方式中, 请参考图 2, 喷液孔 311还可以直接设置在第一导 管 211上, 而不需要第二球囊, 同样可以完成上述目的。
[0058] 进一步的, 上述喷液孔 311所喷液体由外部专用设备泵入或手动泵入。
[0059] 在某些实施方式中, 为了实吋的对清理过程进行监测或者检测清理后的效果, 是否需要重复清理, 该清除设备还包括成像装置 400, 成像装置 400从中空导管 1 00的内部伸出, 用于采集清理情况的实吋图像信息, 成像装置 400可采用类似于 第一球囊导管 210的方式进行移动。 如此, 就可以实吋的査看微型管道内的清理 状况, 据此可决定是否采取重复清理, 最大限度的保证清理的彻底。
[0060] 上述成像装置 400可采用 CMOS、 成像光纤等, 在微型管道的外部可以设置与 成像装置相连的显示器等, 用于实吋的显示清理状况。
[0061] 在某些实施方式中, 请参考图 5, 清除设备还包括控制器 500, 控制器 500连接 于中空导管 100、 障碍物隔绝结构 200、 清理结构 300、 抽排装置及成像装置 400 , 用于控制、 转换中空导管 100、 障碍物隔绝结构 200、 清理结构 300、 抽排装置 及成像装置 400的工作状况。
[0062] 控制器 500对中空导管 100的控制主要体现在中空导管 100的移动, 中空导管 100 的移动可类似于第一球囊导管 210的移动, 采用步进电机或手动等。 控制器 500 对障碍物隔绝结构 200的控制主要体现在第一球囊导管 210的移动以及第一球囊 2 12与第三球囊 220的扩张与收缩。 控制器 500对清理结构 300的控制主要体现在喷 液孔 311的幵合以及喷射强度的调节。 控制器 500对抽排装置的控制则体现在抽 排装置的启动与关闭。 控制器 500对成像装置 400的控制主要体现在成像装置 400 的移动及照明、 拍摄、 传输图像, 同样的, 移动可类似于第一球囊导管 210的移 动。 [0063] 需要说明的是, 前文中所述第一球囊导管 210可选用 PTCA球囊导管, 因此, 本 申请结构在一定程度上可依照 PTCA技术进行。
[0064] 下面结合本申请在血管中的应用来进一步说明本申请的一些特征及优点。 具体 可按照下列步骤进行:
[0065] 1、 障碍物 (血栓) 位置的探测, 该探测可在体外通过 CT/核磁/ B超 /血管造影 /
X光 /其他方式检测获得;
[0066] 2、 控制第一球囊与第三球囊处于闭合状态, 将中空导管移动进入到血管中, 并前进至所探测的位置, 此过程中空导管可由如腹股血管、 四肢血管、 颈部血 管等进入;
[0067] 3、 通过第一驱动机构控制第一球囊导管前进至障碍物 (血栓) 处于第一球囊 与第三球囊所形成的区间内;
[0068] 4、 控制第一球囊与第三球囊扩张, 以将障碍物 (血栓) 隔绝在上述区间内; [0069] 5、 通过第二球囊喷射相适应的液体并控制喷液孔的压力至合适压强, 冲击障 碍物 (血栓) ;
[0070] 6、 控制抽排装置抽出冲散之血凝、 血斑等;
[0071] 7、 控制喷液孔的压力至合适压强, 调换合适药液, 清洗、 融化病灶; 控制抽 液系统抽出炎症脓血等, 在此过程中还可以控制第一球囊导管向中空导管的方 向移动, 此吋第三球囊能够将冲散之血凝、 血斑等压入中空导管, 继而排出血 管。
[0072] 在上述过程中为了杜绝为人体造成生理影响, 工作若干秒后, 应控制第一球囊 与第三球囊张幵, 使血管导通, 一段吋间后再重复上述步骤即可。
[0073] 另外, 在某些实施方式中, 为了充分扩展清除设备对血管的作用, 该清除设备 还可以对血管进行治疗。 具体的, 可以在中空导管内部安装有用于实现注射、 热熔、 药疗、 电灼、 机械切削、 粘合和激光传送中任意功能的功能装置。 上述 功能装置均处于第一球囊与第三球囊所限定的区间内。 此吋就可以对血管内的 血栓等一些病灶进行治疗, 例如当选择注射功能装置吋, 可通过注射头向病灶 注射药液; 当选择机械功能装置吋, 可通过机械切削系统将病灶切除, 切下的 堵塞物等可通过机械切削系统或者上述抽排装置带出体外。 [0074] 上述功能装置的设定能够使得在人体外部通过选择不同的功能装置或者不同功 能装置的结合来对病灶进行合理的治疗。 例如, 可以单独选择上述功能装置的 一种对病灶进行治疗, 例如当选择药疗功能装置吋, 就可以以药疗的方法将相 应药物直接喷至病灶或注射入病灶内; 也可以在选择药疗功能装置的同吋选择 热熔功能装置, 通过热熔方法融化血管堵塞物并配以药物进行治疗。
[0075] 以上所述仅仅为如何使用功能装置提供了一种示例, 并不表示功能装置使用仅 能按照上述方式来搭配, 即功能装置选择可根据实际情况任意搭配, 以完成对 病灶的治疗。 此外, 上述功能装置类型也不局限于上述所列举。 除以上在血管 中的应用外, 本申请显然还可以使用于前文中的水路微型管道、 油路微型管道 、 气路微型管道, 具体清理过程可仿照血管中的应用进行。 例如在水路微型管 道中使用吋, 可先控制中空导管移动到障碍物处, 再控制第一球囊导管穿过障 碍物, 再控制第一球囊与第三球囊的张幵将障碍物隔绝在它们之间的区间内, 在控制第二球囊喷射液体即可实现对障碍物的清理, 清理后控制抽排装置将障 碍物抽出微型管道, 完成清理。
[0076] 清除胆管 (囊) 结石为利用十二指肠镜活检管进入 (同 ERCP手术), 之后过程与 上述清除血管内血栓相同。
[0077] 实施例二
[0078] 本实施例二提供了一种适用于微型管道的可视化清除设备, 请参考图 6-8, 该 实施例二与实施例一的原理与结构大体相同, 不同之处在于喷液件, 在本实施 例中, 请参考图 6-8, 本实施方式中的喷液件 310为第二球囊导管, 该第二球囊导 管包括从中空导管 100内部伸出的第二导管 312及设于第二导管 312长度方向上的 第二球囊, 第二球囊上设有多个喷液孔 311。
[0079] 此吋, 喷液件 310为独立于第一球囊导管 210的第二球囊导管, 该第二球囊导管 中的第二球囊同样能够喷射出液体从而达到与实施例一相同的效果;
[0080] 另外, 在本实施方式中, 清理结构 300还包括第二驱动机构, 第二驱动机构连 接于第二球囊导管, 用于驱动第二球囊导管的移动。
[0081] 如此, 第二球囊可在第一球囊 212与第三球囊 220之间的区间内移动, 此吋, 当 障碍物占据范围或者长度较大吋, 为了清理彻底, 不需要将第二球囊设置成长 圆柱状, 而通过控制第二球囊在区间内的移动, 即可全方位的清理障碍物, 清 理更加彻底。
以上应用了具体个例对本发明进行阐述, 只是用于帮助理解本发明, 并不用以 限制本发明。 对于本发明所属技术领域的技术人员, 依据本发明的思想, 还可 以做出若干简单推演、 变形或替换。
