具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
需要说明的是，在介入医疗领域，通常将器械的距离操作者较近的一端称为器械的近端，将器械的距离操作者较远的一端称为器械的远端，并以此类推器械的各个组件的远端和近端。
以下将结合具体实施例进一步详细说明本发明的技术方案。
实施例1
实施例1中用于具有至少一个空腔的植入体的输送器包括输送手柄、输送 钢缆和芯丝，输送钢缆为管状体，芯丝的近端与输送手柄连接，芯丝的远端从输送钢缆的近端贯穿输送钢缆的远端。植入体可以为肺减容植入体，通过输送器将植入体植入到肺部并释放后，植入体由输送状态下的直线状恢复到自然状态下的预设形状，从而压缩肺组织进而减小肺容积。优选地，预设形状为卷曲状。
请参考图1，实施例1中的植入体100包括植入基体110和连接件120。植入基体110在自然状态下为空间几何卷曲体。植入基体110由记忆合金管(例如镍钛管)通过激光切割、热处理等工艺定型为空间几何卷曲体。由于记忆合金具有超弹性，且植入基体110为中空的管状体，则将一根直线型且具有一定抗弯曲强度的金属丝插入到植入基体110内部后，能够将植入基体110从卷曲状撑直为直线状，且在撤出金属丝后，植入基体110从直线状恢复到自然状态下的卷曲状。
请参考图2，植入体100的连接件120为中空的管状体，其由生物相容性较好的金属或高分子材料通过机械加工、3D打印、粉末冶金、压铸等方式制成。植入基体110和连接件120的连接方式可以为过盈配合、激光焊接、粘接等。连接件120的近端端部优选制成球头状，以便于插入到输送钢缆200的收口钢套210内。
请参考图3，输送钢缆200从远端至近端依次包括收口钢套210、研磨段220、弹簧管230、连接管240和管嘴250。收口钢套210由金属材料通过机械加工制成管状结构，沿其轴向剖开后的剖视图请参考图4，其具有若干个台阶且两端均设有圆形倒角。收口钢套210的内部设有夹头211，夹头211由具有超弹性的合金材料通过机械加工、热定型制成。夹头211包括第一夹杆2111和第二夹杆2112，第一夹杆2111和第二夹杆2112各自的远端在初始状态下相互靠拢，其各自的近端分别固定在收口钢套210的内壁上，且第一夹杆2111和第二夹杆2112构成的整体在初始状态下(即不受外力作用时)的最大外径小于植入体100的连接件120的管状体近端的内径。研磨段220的壁厚小于弹簧管230的壁厚，能够使输送钢缆200的远端的管体更加柔软，以增强输送钢缆200的穿越性能。弹簧管230由多股不锈钢丝绕制而成。连接管240可由现成的金属管或者高分子 管通过机械加工制成，其内径大于芯丝的最大外径。管嘴250为注塑件或者五金包胶件，其近端设有一个连接座251，以将输送钢缆200和输送手柄连接在一起。在弹簧管230上设有一段或多段5-50mm的带有颜色的标记带260，标记带260与输送钢缆200的远端之间的距离为400-900mm。可将弹簧管230进行发黑或者发蓝处理以形成标记带260，也可以通过粘接或热熔附着一段有颜色的高分子材料进行标记，用于提示给操作者输送钢缆200进入人体或动物体的长度。
请参考图5，芯丝300包括金属杆310和加强管320，且加强管320套设在金属杆310的近端段。为了使芯丝300能够更好地支撑植入体100由卷曲状变为直线状，可以在芯丝300的远端设置一段抗弯曲力从中间段向两端逐渐增强的导引段311。导引段311的远端的直径与芯丝300主体部分的直径相同，导引段311的远端至导引段311的中间段的直径逐渐减小，导引段311的中间段至导引段311的近端的直径逐渐增大，直至直径增大到与芯丝300主体部分的直径相同。加强管320套设在金属杆310的近端段，用于增强金属杆310近端段的强度，通常是由金属管或高分子管制成。金属杆310和加强管320可通过焊接或者粘接的方式连接，其中金属杆310的直径为0.5-1.5mm，加强管的外径为0.8-2.5mm。
请一并参考图6-图8，连接件120插入到收口钢套210内，且在芯丝300从输送钢缆200的远端穿出后即可实现植入体100与输送钢缆200的连接。此时，芯丝300将第一夹杆2111和第二夹杆2112分别朝向收口钢套210的内壁撑开，且第一夹杆2111和第二夹杆2112构成的外径大于植入体100的连接件120的管状体近端的内径但小于管状体远端的内径。之后，控制芯丝300继续穿入植入体100的内部，可使植入体100由卷曲状变为直线状。
请一并参考图9-图10，实施例1的输送手柄400上设有第一控件410，且在中空的植入体100与输送钢缆200的远端连接时，第一控件410控制芯丝300(图未示)的远端伸入植入体100内以将卷曲状的植入体100撑直，进而能够实现植入体100在输送器上的装载。第一控件410还能控制芯丝300从植入体100内抽出以释放被撑直的植入体100并使植入体100恢复卷曲状，进而实现植入体100在目标病灶处的释放。优选地，请参考图11，第一控件410包括第一 按键411和导轨412，导轨412为由上下两个杆组成的中空体，第一按键411套设于导轨412的外侧且可沿导轨412进行轴向滑动，芯丝300的近端从导轨412的远端伸入导轨412的内部并与第一按键411连接。芯丝300和第一按键411可通过螺钉压紧连接，或者通过焊接或粘接的方式固定在一起。第一按键411在导轨412上的直线运动方式可采用丝杠螺母机构或齿轮齿条机构等方式，在此不做限定。输送手柄400与芯丝300和输送钢缆200的装配爆炸图请参考图12。可以理解的是，其他实施例中，导轨412可仅由一个杆组成，或者导轨412也可以为管状的中空体。
输送器上设置的第一控件410通过控制芯丝300在输送钢缆200和植入体100连接后形成的通道内的行程，能够简单、便捷地实现植入体100在输送器上的装载和释放，可用在对植入体100的装载、输送、释放和回收的整个植入过程中。且植入体100在装载时不需要借助其他的装载工具，只需将植入体100的连接件120插入输送钢缆200的收口钢套210内，然后通过第一控件410控制芯丝300插入植入体100内即可完成对植入体100的装载。装载后的植入体100被芯丝300约束成直线状，因而可通过输送器继续进行对植入体100的输送操作。待将植入体100输送到目标位置后，通过第一控件410控制芯丝300从植入体100抽出至输送钢缆200内，即可实现对植入体100的释放。在回收植入体100时，可借助其他工具将植入体100的连接件120插入到输送钢缆200的收口钢套210内，然后再通过第一控件410控制芯丝300插入植入体100内并使植入体100呈直线状，便可通过撤出输送器进而回收植入体100。
进一步地，请参考图13，第一按键411上与导轨412接触的部分设有球头件4111，球头件4111优选为滚珠，导轨412的至少与第一按键411接触的面上沿导轨412的轴向间隔地设有多个第一突出部4121，且当第一按键411沿导轨412滑动时，球头件4111与第一突出部4121配合可发出声音，能够提升操作输送手柄时的使用体验。
优选地，本实施例中，输送手柄400上还设有第二控件420，且第二控件420在控制芯丝300相对于输送手柄400静止时，芯丝300在输送钢缆200内不能移动，此时芯丝300处于锁紧状态；第二控件420在未控制芯丝300相对于 输送手柄400静止时，芯丝300处于解锁状态，此时通过第一控件410可控制芯丝300在输送钢缆200内相对输送手柄400移动。
优选地，请一并参考图9和图14，第二控件420包括旋钮421、锁紧座422和锁紧块423，锁紧座422为侧表面上具有一开孔4221的环状体，芯丝300贯穿于锁紧座422的腔体，锁紧块423可从开孔4221伸入锁紧座422的内部，旋钮421为环状体且套设于锁紧座422和锁紧块423的外侧。旋钮421包括相连的第一旋转区4211和第二旋转区4212(图未标，即旋钮421中除第一旋转区4211之外的部分)，以旋钮421的圆心为基准，则第一旋转区4211的内径大于第二旋转区4212的内径，当旋转旋钮421使锁紧块423与第二旋转区4212的内壁接触时，锁紧块423将芯丝300锁紧在锁紧座422的内壁上，当旋转旋钮421使锁紧块423的距离芯丝300较远的一端对应第一旋转区4211的内壁时，芯丝300与锁紧座422之间无相互作用力，也即芯丝300与锁紧座422虽可接触但相互之间无作用力，或者芯丝300与锁紧座422完全分离。
请再次参考图9，第二控件420设置在输送手柄400的远端，且在输送手柄400上距离旋钮421较近的位置设有标识424和标识425，在旋钮421上也设有一个标识426。当旋转旋钮421直到旋钮421上的标识426与输送手柄400上的标识424对齐时，芯丝300被束缚在锁紧座422的内壁和锁紧块423之间，芯丝300需要克服锁紧座422的内壁和锁紧块423对芯丝300的挤压而产生的摩擦力才能移动，因而芯丝300被锁紧块423锁紧在锁紧座422的内壁上，此时通过第一控件410无法使芯丝300(图未标)在输送钢缆200内移动。当旋转旋钮421直到旋钮421上的标识426与输送手柄400上的标识425对齐时，芯丝300从锁紧座422的内壁和锁紧块423之间的束缚中解脱，此时通过第一控件410可控制芯丝300在输送钢缆200内的移动。
通过在输送手柄400上设置第二控件420，可保证植入体100在被芯丝300撑直后持续保持直线状，以便于输送器对植入体100的安全输送，避免了因在输送过程中的误操作而使植入体100在未到达指定位置时被提前释放。
可以理解的是，在其他实施例中，输送手柄400上也可以未设有第二控件420，只要第一控件410可以控制芯丝300移动即可。
优选地，本实施例中，输送手柄400上还设有第三控件430，当第一控件410控制芯丝300在植入体100内移动时，芯丝300的远端较输送钢缆200的远端更靠近植入体100的远端，此时，植入体100不能被释放，第三控件430处于初始的锁定状态；当操作第三控件430以使第一控件410能够控制芯丝300从植入体100内完全抽出，此时，第三控件430处于解锁状态，植入体100被释放并呈卷曲状。操作第三控件430可使其在锁定状态和解锁状态中切换。
优选地，请参考图15，第三控件430包括第二按键431、撬动段432和第一弹性部件433，撬动段432的一端与第二按键431抵接，另一端与第一弹性部件433的一端连接，第一弹性部件433的另一端固定在输送手柄400的内壁上，撬动段432的撬动支点4321固定在输送手柄400的内壁；第二按键431在未被按压时，第一弹性部件433处于压缩状态，且撬动段432的与第一弹性部件433连接的一端在第一弹性部件433的反压缩作用下阻挡第一控件410(图未标)控制芯丝300(图未标)朝向输送手柄400的近端移动；第二按键431在被按压时撬动撬动段432的与第一弹性部件433连接的一端朝向输送手柄400的内壁移动，并进一步压缩第一弹性部件433，能够解除第三控件430对第一控件410控制芯丝300朝向输送手柄400的近端移动的限制。第一弹性部件433优选为弹簧。
在第二按键431未被按压时，第三控件430处于锁定状态，撬动段432的与第一弹性部件433连接的一端在第一弹性部件433的反压缩作用下抵压在第一控件410的导轨412上，阻碍了第一按键411朝近端的移动，此时，第一按键411无法沿导轨412移动到导轨412的近端的末端位置，因而芯丝300也就无法随着第一按键411移动至导轨412的近端的末端位置，而导轨412的近端的末端位置是芯丝300的近端在轴向方向上朝近端移动的最远点，只有芯丝300的近端到达导轨412的近端的末端位置，也即芯丝300从植入体100内完全抽出，植入体100才能被释放。在芯丝300的近端到达导轨412的近端的末端位置之前，也即芯丝300还未从植入体100内完全抽出时，通过滑动第一按键411朝向远端移动，仍可继续操作以将植入体100撑直。
在第二按键431被按压直至撬动段432的与第一弹性部件433连接的一端 朝向输送手柄400的内壁移动且不再对第一按键411的轴向移动产生阻碍时，第三控件430处于解锁状态，设置在输送手柄400内部并与第二按键431连接的第五弹性部件434被压缩，同时，第二按键431推动撬动段432的与第二按键431连接的一端朝远离第二按键431的方向移动，在撬动支点4321的作用下，撬动段432的与第一弹性部件433连接的一端朝远离导轨412的方向移动，从而解除对第一按键411朝向近端移动的阻碍，此时，第一按键411能够带动芯丝300移动至导轨412的近端的末端位置，从而解除植入体100的连接件120与输送钢缆200的收口钢套210的连接，进而可对植入体100进行释放。在松开第二按键431后，第五弹性部件434回位并带动第二按键431移动到被按压前所处的位置。第五弹性部件434优选为弹簧。
需要说明的是，撬动段432的与第一弹性部件433连接的一端与导轨412的近端的末端之间的距离L1，可根据植入体100的连接件120与输送钢缆200的收口钢套210由连接状态变为未连接状态的过程中芯丝300移动的最小距离L2而定，且L1大于或等于L2。
通过在输送手柄400上设置第三控件430，以限制植入体100在未被释放时芯丝300朝向近端移动的最远位置，从而避免在植入体100未被确认需要释放时因误操作而使植入体100被释放的情况的发生，且只有在第三控件430处于解锁状态时，植入体100才能被成功释放，提高了植入体100在植入过程中的安全性。
可以理解的是，在其他实施例中，输送手柄400上也可以未设有第三控件430，只要第一控件410可以控制芯丝300移动即可。
进一步地，输送手柄400上还设有第四控件440和若干个档位451，其中，不同的档位451距离输送手柄400的远端的末端的距离不同，第四控件440用以选择一个合适的档位451以限定芯丝300的远端穿出输送钢缆200的远端的最大距离。
由于人体肺脏的解剖结构比较复杂，相应地有多种不同规格的植入体100，不同规格的植入体100在由空间弯曲状展开成直线状后的长度不同，展开后的长度通常为50-200mm。在输送手柄400上设置不同的档位451，且当第四控件 440与某一档位451配合时，第一控件410控制芯丝300的远端穿出输送钢缆200的远端的最大距离被限定，从而可以根据输送器上档位451设置的不同而使输送器只能装载与相应档位451匹配的植入体100。
优选地，请一并参考图16-图18，对于在输送手柄400上设置的每一个档位451，在输送手柄400的内壁对应设有一个第二突出部452，第四控件440(图未标)包括第三按键441、卡位块442和限位块443，卡位块442上设有与第二突出部452配合的第一凹槽4421，且与第一凹槽4421相对的一侧设有若干个第二凹槽4422，限位块443的一侧设有与第二凹槽4422配合的第三突出部4431，且另一侧的远端设有第四突出部4432，卡位块442与限位块443通过至少一个第二弹性部件444连接。优选地，输送手柄400上设有3个档位451，相应地，输送手柄400的内壁上设有3个第二突出部452。优选地，卡位块442上设有4个第二凹槽4422，限位块443上设有2个第三突出部4431，卡位块442与限位块443通过2个第二弹性部件444连接，且第二弹性部件444与第三突出部4431间隔设置，第二弹性部件444的一端与限位块443连接，另一端垂直地固定在卡位块442中无需与第三突出部4431配合的第二凹槽4422内。限位块443上设置的第四突出部优选地设置在限位块443的远端，且抵压在导轨412的远端以阻碍第一按键411(图未标)朝向远端的移动。第二弹性部件444优选为弹簧。
在输送手柄400(图未标)的近端设有一个长条形的开口445，设置的不同档位451分别分布在开口445的轴向边缘。第三按键441的顶部位于开口445的上方且与开口445间隔一定距离，其底部伸入开口445内并与卡位块442连接，连接方式可以为卡扣连接或粘结等方式。第三按键441与卡位块442连接后可作为一个整体沿着开口445进行轴向移动。
在第三按键441未被按压时，第二弹性部件444处于被压缩状态，且在第二弹性部件444的反压缩作用下第二突出部452与第一凹槽4421卡合，从而被卡合的第二突出部452对应的档位451被选定。请参考图19，在第三按键441被按压直至第二突出部452从第一凹槽4421中抽出时，卡位块442的第二凹槽4422与限位块443的第三突出部4431卡合，且卡位块442和限位块443均随着第三按键441的移动而移动。请一并参考图20-图21，当卡位块442和限位块 443随着第三按键441的移动而移动到当前所选档位451对应的第二突出部452的位置，且第一凹槽4421与当前的第二突出部452在松开第三按键441后卡合，从而通过第四控件440成功更换档位451，也即重新限定了芯丝300的远端穿出输送钢缆200的远端的最大距离。
可以理解，当选择最远端的档位451时，芯丝300的远端穿出输送钢缆200的远端的最大距离与其他档位451相比值最大，对应可装载最大规格的植入体100；当选择最近端的档位451时，芯丝300的远端穿出输送钢缆200的远端的最大距离与其他档位451相比值最小，对应可装载最小规格的植入体100。
可以理解的是，在其他实施例中，输送手柄400上也可以未设有第四控件440，只要第一控件410可以控制芯丝300移动即可。
可以理解的是，本发明用于输送的具有至少一个腔体的植入体也可以为输送用于栓塞的弹簧圈，不限于本实施例中的用于肺减容的植入体，只要输送的植入体在输送时被芯丝撑直且释放后呈卷曲状即可。
实施例2
实施例2中与实施例1相同的部分在此不再赘述，请参考图22，其区别主要在于，第四控件440包括第四按键446和档位底板447，第四按键446的中部固定在输送手柄400(图未标)上，第四按键446与档位底板447相对的一侧的两端分别设有一个限位凸台4461，档位底板447与第四按键446相对的一侧设有至少两个第三凹槽4471，第四按键446与档位底板447通过与第三凹槽4471配合的限位件4462连接；第四按键446通过控制限位件4462与不同的第三凹槽4471的配合以限制第一控件410(图未标)控制芯丝300(图未标)穿出输送钢缆200(图未标)的远端的距离。
在其中的一个实施方式中，在输送手柄400的近端设有一个开口，在开口的轴向边缘设置有2个不同的档位，分别分布在该开口的近端和远端。第四按键446的顶部位于开口的上方且与开口间隔一定距离，其底部伸入该开口内以与档位底板447配合连接。档位底板447上设有3个相邻的第三凹槽4471。请参考图23，限位件4462(图未标)包括固定管44621、第三弹性部件44622和滚珠44623。固定管44621的一端固定在第四按键446上且位于两个限位凸台 4461的中间位置，第三弹性部件44622收容于固定管44621内且一端与第四按键446连接，另一端与滚珠44623连接。第三弹性部件44622处于被压缩状态，使得限位件4462与档位底板447连接时，滚珠44623被抵压在档位底板447的第三凹槽4471内且部分地收容于固定管44621内。第三弹性部件44622优选为弹簧。
请再次参考图22，当滚珠44623被抵压在最左侧的第三凹槽4471内时，左侧的限位凸台4461高于右侧的限位凸台4461，右侧的限位凸台4461阻碍了第一按键411沿导轨412(图未标)朝向远端的移动，也即当第一按键411移动到与右侧的限位凸台4461接触的位置时，芯丝300(图未标)处于可穿出输送钢缆200(图未标)的远端的最远位置。在当前档位处可装载最小规格的植入体100。
请再次参考图23，当滚珠44623被抵压在位于中间位置的第三凹槽4471内时，左侧的限位凸台4461与右侧的限位凸台4461的高度相同，左侧的限位凸台4461和右侧的限位凸台4461均未能阻碍第一按键411沿导轨412(图未标)朝向远端的移动，此时，芯丝300(图未标)可穿出输送钢缆200(图未标)的远端的最远位置由第一按键411沿导轨412的远端可移动的最远位置决定，且由于第一按键411可移动至导轨412的远端的末端，因而当前档位允许装载最大规格的植入体100(图未标)。
请参考图24，当滚珠44623被抵压在最右侧的第三凹槽4471内时，左侧的限位凸台4461低于右侧的限位凸台4461，右侧的限位凸台4461未能阻碍第一按键411沿导轨412(图未标)朝向远端的移动，左侧的限位凸台4461阻碍了第一按键411沿导轨412(图未标)朝向远端的移动，也即当第一按键411移动到与左侧的限位凸台4461接触的位置时，芯丝300(图未标)处于可穿出输送钢缆200(图未标)的远端的最远位置。在当前档位处可装载规格居中的植入体100(图未标)。
在另一实施例中，限位件4462包括盲管和第四弹性部件，盲管的底部为球头状，第四弹性部件部分地收容于盲管内，且其收容于盲管内的一端与盲管的底部连接，另一端与第四按键446连接。
以植入体100在输送钢缆200内的输送为例，输送过程包括以下步骤：通过支气管镜建立植入体100被植入时的工作通道，具体地，经口或鼻插入支气管镜，且支气管镜在插入体内后可将支气管镜的远端探测到的图像传输至监测器上进行显示，以便操作者引导支气管镜的远端进入到人体肺部的支气管中；借助医学成像设备和已建立的工作通道，通过现有的测量技术获得所需植入的植入体100的规格参数；将输送器的输送鞘管插入到支气管镜的工作通道内，并引导输送鞘管的远端进入到人体内的目标区域；根据测量得到的植入体100的规格参数选择合适的植入体100，并将输送手柄400的第四按键446滑动到与所选植入体100的规格参数匹配的档位；将植入体100的连接件120插入到输送钢缆200的收口钢套210内，推动输送手柄400的第一按键411直至不能移动，此时，植入体100由弯曲状变为直线状，从而完成了对植入体100的装载；旋转旋钮421以将芯丝300锁紧在锁紧座422上；将已装载的植入体100插入到输送鞘管内，推动输送钢缆200以将植入体100输送到支气管中指定的位置；旋转旋钮421以解除对芯丝300的锁定；推动第一按键411直至不能再移动；在确认要释放植入体100时，按住输送手柄400的近端的第二按键431，然后推动第一按键411直至不能再移动，从而完成对植入体100的释放；最后，依次撤出输送钢缆200和输送鞘管，由此便完成了对植入体100的植入；调整支气管镜至合适位置，以便按照上述步骤植入下一个植入体100；待完成对所有植入体100的植入后，撤出支气管镜。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
