目前，对于良性前列腺增生的治疗手段有药物治疗和手术治疗两种方式，其中手术治疗包括：(1)经尿道前列腺电切术；(2)耻骨上或耻骨后前列腺切除术；(3)激光前列腺剜除术或切除术；(4)植入物的微创伤治疗术等。现有技术中的一种用于良性前列腺增生的永久性植入物产品的作用机制是通过输送系统向体内植入植入物，利用植入物机械性地将前列腺两叶分开，使其不再阻塞尿道。向体内植入植入物可以持续地缓解BPH患者的症状，且无需进行前列腺组织的切除与消融，减轻患者的痛苦，可使患者尽快恢复正常生活。
现有技术中输送系统首先利用穿刺针将植入物植入人体，然后回撤穿刺针，最后利用输送系统上的剪断推送机构剪切植入物上多余的连接件。然而现有输送系统的结构缺陷，使得医护人员在使用的过程中易出现误操作，而导致穿刺针回撤与剪断推送机构剪切连接线同时进行，从而造成植入物植入失败；现有输送系统在使用时也易因器械故障而在释放植入物时出现卡阻，导致植入物释放失败，这些问题影响了输送系统的使用可靠性。

具体实施方式
为使本发明的目的、优点和特征更加清楚，以下结合附图对本发明作进一步详细说明。需说明的是，附图均采用非常简化的形式且均使用非精准的比例，仅用以方便、明晰地辅助说明本发明实施例的目的。
如在本说明书中所使用的，单数形式“一”、“一个”以及“该”包括复数对象，复数形式“多个”包括两个以上的对象，除非内容另外明确指出外。如在本说明书中所使用的，术语“或”通常是以包括“和/或”的含义而进行使用的，除非内容另外明确指出外，以及术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接。可以是机械连接，也可以是电连接。可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。附图中相同或相似的附图标记代表相同或相似的部件。
本实施例提供了一种植入物输送系统及用于该植入物输送系统的操作系统。所述植入物输送系统用于向人体内输送医用植入物。为便于理解，在下文的描述中以治疗良性前列腺增大为例来介绍该植入物输送系统。
本实施例中采用所述植入物输送系统向前列腺组织植入医用植入物，利用植入物输送系统中的植入物机械性地将前列腺的两叶分开而使尿道通畅。图1示出了医用植入物植入前列腺的示意图。如图1所示，所述植入物输送系统包括植入物1，所述植入物1包括依次连接的远端锚定件11、连接件12和近端锚定件13。其中，所述远端锚定件11与所述连接件12可压接固定装配，并预先安装于一穿刺针(图1中未示出)内，而所述近端锚定件13预先安装在一输送管(图1中未示出)内。采用所述植入物输送系统输送植入物1时，所述穿刺针首先携带远端锚定件11刺入前列腺S的包膜，并将所述远端锚定件11定位在前列腺S的远端上，之后所述植入物输送系统回收穿刺针并拉紧所述远端锚定件11，然后所述植入物输送系统将所述近端锚定件13推送至与所述连接件12接合，以使所述近端锚定件13定位在前列腺S的近端，最后所述植入物输送系统剪断植入物1上多余的连接件12以完成整个输送过 程。根据患者的情况，需要在前列腺的两叶上各植入4-6个植入物1，通过植入物1将前列腺两叶分开而使尿道P通畅。这里所述的“近端”是指前列腺组织中紧邻尿道的部分，而所述“远端”则是相对于所述近端而言，距离所述尿道较远的前列腺组织。
在将所述远端锚定件11植入前列腺组织中时，所述穿刺针刺入前列腺组织的深度一般为30-35mm。如图2所示，为使穿刺针2更好地刺入前列腺组织，穿刺针2的头端被设计为弧形结构，优选该弧形结构的弧度为90°。进一步地，如图3所示，所述穿刺针2的头端还设计有刃脚，该刃脚的角度可为15°-20°，例如该刃脚的角度可为17°、18°、19°等。所述穿刺针2的头端，是指穿刺针2首先接触前列腺组织的一端。
接下来请参阅图4至图8，在本发明的一个实施例中，可以通过手动操作来完成植入物的释放。具体地，所述植入物输送系统包括相互连接的操作系统3和输送管4，所述输送管4至少包括第一管道41和第二管道42，所述第一管道41用于容纳所述穿刺针(图3及图4中未示出)，并与所述穿刺针间隙配合，以使所述穿刺针能够在第一管道41内沿轴向移动。所述第二管道42用于容纳所述近端锚定件(图3及图4中未示出)，所述近端锚定件可在所述第二管道42中沿轴向移动。所述操作系统3包括壳体31和触发装置32，所述壳体31具有内腔(图中未标注)，所述触发装置32的一部分构件设置于所述内腔中，另一部分构件则位于所述壳体31外，具体根据实际情况设置。所述输送管4与所述壳体31连接，并与所述内腔相贯通，所述穿刺针与所述触发装置32连接，所述触发装置32用于释放以及回收所述穿刺针，同时还用于剪断所述植入物上多余的连接件12。所述触发装置32与所述穿刺针、所述近端锚定件的位置关系、连接关系，以及触发装置32的具体工作方式将在下文中进行描述。
可选地，本实施例中所述壳体31包括相互拼接的第一壳体(图中未标注)和第二壳体(图中未标注)，所述第一壳体和所述第二壳体之间形成所述内腔。采用拼接式的壳体31便于组装操作系统3，简化生产过程。
如图8所示，所述触发装置32至少包括回撤锁321、剪断锁322及剪断 推送机构323，其中所述回撤锁321及所述剪断锁322均部分位于所述内腔中，所述剪断推送机构323用于剪切所述植入物上多余的连接件12。在释放植入物之前，所述操作系统3处于初始位置，在所述初始位置，所述回撤锁321被锁定，且所述回撤锁321还用于锁定所述剪断锁322，而所述剪断锁322用于锁定所述剪断推送机构323。当所述回撤锁321被解锁后，所述回撤锁321能够在外力的作用下解除对所述剪断锁322的锁定，进而所述剪断锁322能够在外力的作用下解除对所述剪断推送机构323的锁定。可理解，在将所述操作系统3应用于植入物输送系统中，并用于输送植入物时，所述回撤锁321在穿刺针释放之后再解锁。也就是说，在本实施例中，在所述初始位置，利用所述回撤锁321锁定剪断锁322，可避免在穿刺针释放前或释放中出现剪断锁322提前解锁的误操作。另外，本实施例中所述“外力”是指对于接受作用力的元件而言，所述作用力来自其他元件或机构。
进一步地，所述触发装置32还包括限位机构324、释放器325及传动器326，所述释放器325可转动地设置于所述内腔中并与所述穿刺针连接，所述传动器326可活动地设置于所述内腔中并与所述回撤锁321连接。在所述初始位置，所述限位机构324用于锁定所述回撤锁321。所述释放器325在外力作用下沿第一方向旋转预定角度，以释放所述穿刺针而使所述穿刺针刺入前列腺组织中。当所述释放器325转过所述预定角度时，所述释放器325撞击所述限位机构324而对所述限位机构324施加作用力，以使所述限位机构324产生变形而解除对所述回撤锁321的锁定。之后，所述回撤锁321便可在外力的作用下解除对所述剪断锁322的锁定，同时所述回撤锁321还用于驱动所述传动器326运动，并由所述传动器326驱动所述释放器325沿第二方向运动，所述第二方向与所述第一方向相反。利用限位机构324锁定回撤锁321，并通过释放器325来解除限位机构324对所述回撤锁321的锁定，同时所述回撤锁321在解除对剪断锁322的锁定过程中，所述回撤锁321还驱动传动器326运动，进而推动释放器325反向转动以回收所述穿刺针，最后所述剪断锁322解除对所述剪断推送机构323的锁定，以使所述剪断推送机构323启动。可理解，本实施例所述的第一方向为顺时针方向时，所述第二方向为 逆时针方向，反之亦可。
换言之，本实施例所述的操作系统3应用于植入物输送系统时，在对植入物进行释放之前，所述触发装置32处于所述初始位置，并且在所述初始位置，所述限位机构324、所述回撤锁321、所述剪断锁322及所述剪断推送机构323处于相互锁定的状态。而且只有在外力的作用下使所述释放器325旋转以释放穿刺针之后，才能够解除对所述回撤锁321的锁定，进而所述剪断锁322才可解锁。由此，可使得所述输送系统完全按照预定顺序释放，这样一环环锁定的效果在于：所述输送系统在输送植入物时按照预定顺序进行解锁触发，避免出现操作顺序错误而导致植入物释放失败的问题，以提高所述植入物输送系统的可靠性及安全性。
可选地，所述触发装置32还包括释放锁，在所述初始位置，所述释放锁用于锁定所述释放器325。具体而言，所述释放锁包括第一操作机构327和第二操作机构328，在所述初始位置，所述第一操作机构327用于锁定所述第二操作机构328，所述第二操作机构328用于锁定所述释放器325。
实践中，所述第一操作机构327可在外力的作用下运动而实现对所述第二操作机构328的解锁。所述第二操作机构328可在外力的作用下运动而实现对所述释放器325的解锁。所述回撤锁321可在外力的作用下运动而实现对所述剪断锁322的解锁。所述剪断锁322可在外力的作用下运动而实现对所述剪断推送机构323的解锁。
接下来结合图8至图15介绍所述触发装置32中各个组成部件的可选结构及装配关系。应理解，以下实施例中所述触发装置32的各个组成部件的具体结构及装配关系仅仅是本发明的一种实现方式，其并不是唯一选择，因而不应当对发明构成限制。

请参阅图8及图9，在所述初始位置，所述第三限位部3271抵靠在所述 操作部3281上，以实现对所述第二操作机构的328的锁定。请参阅图8及图10，所述第四限位部3282抵靠在所述第一限位部3284上，同时所述第一限位部3284抵靠在所述释放器325上，以实现对所述释放器325的锁定。请参阅图8及图14，所述第一限位柱3241可用于限制所述回撤锁321沿第三方向转动，例如所述第一限位柱3241通过抵靠在所述传动器326的突出部3262上来限制所述回撤锁321沿第三方向运动。请参阅图8及图11，所述第二限位柱3242可用于抵靠在所述回撤锁321上，例如所述第二限位柱3242可用于抵靠在所述第五限位部3212上以限制所述回撤锁321沿第四方向转动，从而所述回撤锁321被所述限位机构324锁定。请参阅图11及图12，所述第五限位部3212抵靠在所述剪断锁322上，较佳地，所述第五限位部3212抵靠在所述第六限位部3221上，以实现对所述剪断锁322的锁定，如此设置，一方面可简化触发装置32的结构，减小操作系统3的体积，另一方面在本实施例中只要第五限位部3212与第六限位部3221分离即可实现对剪断锁322的解锁，相较于其他形式例如结构断裂、结构变形等解锁方式，可降低各锁定机构的解锁难度，进而降低植入物释放时出现卡阻的风险。同时，请参阅图13，在所述初始位置，所述第一抵推部3251与所述第二限位柱3242之间存在周向间隔，所述第三抵推部3252与所述第二抵推部3261之间存在周向间隔。另外，本实施例中，所述第三方向与所述第四方向相反，例如所述第三方向可为顺时针方向，第四方向为逆时针方向，反之亦可。
本实施例中，所述第一操作机构327为一安全机构，其只有在受到外力的作用下才可以发生运动。请继续参阅图9及图10并结合图15及图16，首先拨动所述第一拨动部3273，使得第一操作机构327转动，从而所述第三限位部3271不再抵靠在所述操作部3281上。然后按压所述操作部3281，以使所述操作部3281转动，从而所述第四限位部3282抵推所述第一限位部3284，进而所述第一限位部3284随之转动，并远离所述释放器325。之后所述释放器325可在驱动力的作用下旋转(例如顺时针转动)预定角度以释放所述穿刺针(如图17所示)，并且当释放器325旋转至极限位置后，释放器325上的第一抵推部3251撞击所述第一限位柱3241，以使所述第一限位柱3241产 生变形而解除对所述回撤锁321沿第三方向运动的限制，同时所述第三抵推部3252与所述第二抵推部3261相接触。接着，按压所述回撤锁321，使得所述回撤锁321顺时针转动，从而所述第五限位部3212远离所述剪断锁322以解除对所述剪断锁322的锁定。与此同时，所述回撤锁321还带动所述传动器326逆时针转动(以释放穿刺针时所述释放器325顺时针转动为前提)，这样所述第二抵推部3261可抵推所述第三抵推部3252进而推动所述释放器325逆时针转动以回收所述穿刺针。最后，推动第二拨动部3224以使所述剪断锁322运动来解除对所述剪断推送机构323的锁定。
应知晓，本实施例中用于驱动所述释放器325转动以释放所述穿刺针的驱动力可由电机、弹簧机构或磁力机构等装置提供，对此本实施例不做限定，图示中亦未示出。对于本领域技术人员而言，不论采用何种装置来提供驱动力，该机构与所述释放器的配合都是常规技术手段，故而此处不作详细介绍。另外，通过所述回撤锁321的顺时针转动带动所述传动器326进行逆时针转动，是本领域技术人员所熟知的公知常识。此外，所述第一操作机构327、第二操作机构328、回撤锁321以及剪断锁322的运动可通过按压、转动、滑动等多种方式实现，对此，本实施例并不作严格限制。
在触发装置32的解锁过程中，所述释放器325撞击所述第一限位柱3251时可发出撞击声，以便于操作者知晓释放器325已旋转到极限位置。同时，所述传动器326上还可设置有棘齿3264，壳体31上对应地设置有接触片313，所述接触片313与所述棘齿3264接触。所述传动器326转动时，所述棘齿3264因与所述接触片313接触而发出拨齿声，这样当所述传动器326转动到极限位置而停止转动时，拨齿声消失，亦可方便操作者使用。
另外，在其他实施例中，所述第二操作机构328也可不包括第一限位部3284，此时，所述操作部3281上的第四限位部3282用于直接抵靠在所述释放器325上以实现对所述释放器325的锁定。
进一步地，如图8、图18及图19所示，所述剪断推送机构323包括滑槽3231、第一推送块3232、推送弹性件3233、第二推送块3234、第二限位部3235、推杆3236及剪断部3237。所述滑槽3231可为长条状并设置于所述内 腔中，所述第一推送块3232和所述第二推送块3234均可活动地设置在所述滑槽3231上，所述推送弹性件3233连接所述第一推送块3232和所述第二推送块3234。所述第二限位部3235位于所述第一推送块3232和所述第二推送块3234之间，并可转动地设置于内腔中。所述推杆3236的一端与所述第一推送块3232连接，另一端伸入所述输送管4的第二管道42中，并用于推送容纳于所述第二管道42中的近端锚定件13。所述剪断部3237设置于所述第二管道42中，并位于所述近端锚定件13远离所述壳体31的一侧，且所述剪断部3237与所述第二推送块3234连接。本实施例中，所述推送弹性件3233包括但不限于弹簧。
在所述初始位置，所述推送弹性件3233处于伸长状态(相对于推送弹性件的原长而言)。所述第一推送块3232用于与所述剪断锁322上的卡锁钩3222连接，这样，所述第一推送块3232被锁定。所述第二限位部3235用于抵靠在所述第二推送块3234上，以使所述第二推送块3234保持静止。在所述剪断锁322被解锁之后，所述剪断锁322可在外力的作用下转动，以使所述第一推送块3232与所述剪断锁322相脱离。这样，所述推送弹性件3233释放弹力，并带动所述第一推送块3232沿所述滑槽3231向所述第二推送块3234移动(以图18中所示方位为例，所述第一推送块3232向左移动)，直至所述第一推送块3232撞击所述第二限位部3235，使得所述第二限位部3235转动而远离所述第二推送块3234，从而第二推送块3234可在所述推送弹性件3233的作用下沿所述滑槽3231朝向所述第一推送块3232移动(即向右移动)。在此过程中，所述推杆3236随所述第一推送块3232向左移动，并推动所述近端锚定件13向左运动，所述剪断部3237则随第二推送块3234向右运动，直至所述近端锚定件13卡在植入物1的连接件12上，之后所述剪断部3237可剪切所述植入物1上多余的连接件12。
通过以上介绍可知，本实施例所提供的输送系统中，在初始位置所述第一操作机构327、第二操作机构328、回撤锁321、剪断锁322及剪断推送机构323均处于联锁的状态。而在释放植入物的过程中，首先施加作用力以使第一操作机构327运动而解除对所述第二操作机构328的锁定，之后第二操 作机构328可被触发。当第二操作机构328被触发时，所述穿刺针被释放，同时解除对所述回撤锁321的锁定，之后所述回撤锁321可被触发。当所述回撤锁321被触发时，所述穿刺针被回收，同时解除对所述剪断锁322的锁定，之后所述剪断锁322可被触发。当所述剪断锁322被触发时，所述剪断推送机构323即被解除锁定而能够实现剪断功能。这样一来，所述操作系统必须按照预定顺序触发，从而使得所述输送系统可完全按照预定的顺序释放植入物，以避免因触发顺序错误而造成释放失败。
可选地，在所述初始位置，所述回撤锁321还可用于锁定所述第二限位部3235，而当所述回撤锁321受到外力作用时，所述回撤锁321解除对所述第二限位部3235的锁定。具体地，在所述初始位置，所述回撤锁321可抵靠在所述第二限位部3235上以使所述第二限位部3235不能转动，从而实现对所述第二限位部3235的锁定。当所述回撤锁321在外力下运动时，回撤锁321与所述第二限位部3235相脱离而解除对所述第二限位部3235的锁定。
另外，为方便按压所述第二操作机构328，所述第二操作机构328的操作部3281上还可设置按压防滑纹。同理，所述回撤锁321上也可以设置按压防滑纹。
所述输送系统按照上述的释放过程来输送植入物时，有可能会发生卡阻，例如，第二操作机构328转动以解除对释放器325的锁定时发生卡阻。再如，释放器325撞击限位机构324以使所述限位机构324产生变形时发生卡阻。又如，剪断锁322转动而解除对所述剪断推送机构323的锁定，以使所述第一推送块3232撞击所述第二限位部3235时发生卡阻等。任一个程序的卡阻都会导致植入物释放失败。对此，本发明的又一个实施例中，所述的操作系统还包括手动操作机构，所述壳体31上还开设有窗口，也就是说，本实施例利用手动操作机构从所述窗口处伸入所述内腔来触发各个部件，以解决卡阻的问题。
请参阅图20、图21及图22，所述壳体31上开设有与所述内腔相贯通的第一窗口314，当所述释放器325的解锁出现卡阻时，所述手动操作机构33能够从所述第一窗口314伸入所述内腔，并对所述第二操作机构328施加作 用力，使所述第二操作机构328解除对所述释放器325的锁定。具体地，所述第一窗口314被设置在所述壳体31与所述操作部3281相对应的位置，这样所述手动操作机构33可从第一窗口314伸入所述内腔并向所述操作部3281施加作用力，以驱动所述操作部3281转动，并带动所述第一限位部3284转动而远离所述释放器325，从而解除对释放器325的锁定。或者，所述第一窗口314被设置在所述壳体31与所述第一限位部3284相对应的位置，以便于所述手动操作机构33从第一窗口314伸入所述内腔，而对所述第一限位部3284施加作用力，从而所述第一限位部3284转动而远离所述释放器325。本实例中，所述第一限位部3284优选采用弹性材料制作，这样所述第一限位部3284在手动操作机构33的作用下，还可通过变形来解除对所述释放器325的锁定。
所述壳体31上还可开设与所述内腔相贯通的第二窗口315，当所述释放器325撞击限位机构324以使所述限位机构324产生变形时发生卡阻，可使所述手动操作机构33从所述第二窗口315伸入所述内腔，并对所述限位机构324施加作用力而使所述限位机构324产生变形。具体地，所述第二窗口315可设置在所述壳体31与所述第一限位柱3241相对应的位置，以方便所述手动操作机构33从第二窗口315处对所述第一限位柱3241施加作用力。作为优选，所述第一限位柱3241采用弹性材料制作。
所述壳体31上还可开设与所述内腔相贯通的第三窗口316，当所述第一推送块3232撞击所述第二限位部3235时发生卡阻，可使所述手动操作机构33从所述第三窗口316伸入所述内腔，并对所述第二限位部3235施加作用力，以使所述第二限位部3235沿远离所述第二推送块3234的方向运动而解除对所述第二推送块3234的锁定。
所述手动操作机构33的具体形式可根据各个窗口的形状、大小来确定。图22示出了一种可选的手动操作机构33的结构示意图，如图22所示，所述手动操作机构33包括第一释放部331、第二释放部332和第三释放部333。在本实施例中，各个窗口的大小、形状均不相同，因此所述第一释放部331、所述第二释放部332及第三释放部333也有所不同，在这种情况下，所述第 一释放部331可用于从第一窗口314伸入所述内腔，所述第二释放部332可用于从所述第二窗口315伸入所述内腔，所述第三释放部333可用于从所述第三窗口316伸入所述内腔。在其他实施例中，所述手动操作机构上也可只设计一个释放部，该释放部可从三个窗口中的任一个伸入所述内腔。
以上介绍了本实施例中的输送系统通过操作系统来实现对所述植入物的输送过程。通过采用可联锁的触发机构来确保输送系统严格按照预定顺序释放植入物，确保输送过程安全可靠。同时利用手动操作机构来消除卡阻问题，进一步提高输送系统使用的有效性。
另外，如图4及图5所示，在实践中所述输送管4通过输送管连接件5与所述壳体31连接。如图23所示，所述输送管连接件5包括卡板51，所述卡板51固定于所述壳体31上，且所述卡板51上设有连接凸台52，所述连接凸台52及所述卡板51上均开设有与所述内腔连通的通孔53，从而所述输送管4可通过所述通孔53与所述内腔贯通。所述连接凸台52的周向外侧壁上还设有圆弧凸起54。
进一步地，为使所述植入物输送系统能够准确可靠地将所述植入物输送至体内，所述植入物输送系统上还连接有内窥镜、鞘管等构件。为此，如图4及图5所示，所述植入物输送系统还包括镜鞘锁6和窥镜锁7。
如图24所示，所述镜鞘锁6包括卡爪锁61和圆弧卡环62，所述卡爪锁61用于连接鞘管，所述圆弧卡环62与圆弧凸起54连接。如图25所示，所述窥镜锁7可转动地设置于所述壳体31上，且所述窥镜锁7包括安装孔71，所述安装孔71用于连接内窥镜。在输送植入物时，所述内窥镜用于伸入体内以观察所述穿刺针是否携带所述远端锚定件到达预定位置，因此，如图6及图7所示，所述输送管4上还相应地设有第三管道43，所述第三管道43用于容纳所述内窥镜。进一步地，所述第一管道41、所述第二管道42及所述第三管道43的管壁相互连接，使得在垂直于输送管4的轴向上，所述第一管道41、第二管道42及第三管道43可排成一列。所述输送管4还包括管道头44，所述管道头44同时与所述第一管道41、第二管道42及第三管道43连接，并且所述管道头44与所述第一管道41连通，以形成穿刺通道。所述管道头44用于 引导穿刺针从直线运动转变为弧线运动，这样所述穿刺针从所述第一管道41经过所述管道头44，再刺入前列腺组织。进一步地，因管道头44上形成有沟槽，故所述管道头44上还包裹有保护膜45，以避免管道头44对人体组织造成不必要的损伤。应知晓，所述输送管4、输送管连接件5、镜鞘锁6、窥镜锁7的具体结构及其与壳体31的连接关系，对于本领域技术人员而言均为公知常识。
进一步地，基于所述的植入物输送系统，本发明实施例还提供了一种植入物输送方法。在输送植入物之前，所述操作系统处于所述初始位置，因此所述植入物输送方法包括：
