除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。术语“上”、“下”、“左”、“右”“前”、“后”、“顶”、“底”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
需要说明的是，根据本公开实施例的外科手术器械用于结扎目标组织；在下面的描述中，以目标组织作为参照，前端是指靠近目标组织的一端而后端是指远离目标组织的一端，前侧是指靠近目标组织的一侧而后侧是指远离目标组织的一侧。
例如，在手术过程中，由于对结扎夹数量的要求，使得操作者需要多次 进行施夹操作，这样既降低了工作效率，增加手术时间，增大患者出血量，延长患者恢复时间，也增加了患者的经济压力。于是，能够连续送夹的外科手术器械应运而生，但是能够连续送夹的外科手术器械的夹仓装置体积较大，从而增加了储藏医疗器械的压力。
请参见图1至图4，根据本公开实施例的外科手术器械包括握持部100及与握持部100连接的工作部200，握持部100或工作部200包括驱动装置2；工作部200包括：限定内腔的外壳1；设置在内腔中且与驱动装置2连接的击发施力件3；与击发施力件3连接的击发套管4；以及由驱动装置2驱动的夹仓装置5。外壳1上设置有安装口11，夹仓装置5通过安装口11与工作部200可拆卸连接。将夹仓装置5整体与工作部200可拆卸设置，当夹仓装置5内的结扎夹53用完后，可从安装口11处将夹仓装置5取出以更换新的夹仓装置5，实现握持部100及工作部200的重复利用，达到节约资源及成本的效果。另外，将夹仓装置5整体与工作部200可拆卸设置，从而可以将夹仓装置5和工作部200分别单独存放，增加了储藏医疗器械的灵活度，降低了储藏医疗器械的压力。
如上所述，握持部100和工作部200包括驱动装置2。在此情形下，整个驱动装置2设置于握持部100；或者，整个驱动装置2设置于工作部200；或者，驱动装置2的一部分设置于握持部100而驱动装置2的另一部分设置于工作部200。
例如，击发套管4设置在外壳1所限定的内腔之外；击发套管4的后端与击发施力件3连接；如下所述的设置在夹仓壳体51前端的开口513与击发套管4连通，如下所述的至少两个仓体52展开后经夹仓壳体51前端的开口513依次进入击发套管4，且如下所述的夹钳59穿过击发套管4并从击发套管4的前端露出。
例如，如图1所示，击发套管4上设置有拨盘41，用于调节施夹角度。
根据本公开的实施例，提供一种夹仓装置5，该夹仓装置5与如上所述的工作部200可拆卸连接。例如，结合图5至图13，夹仓装置5包括：夹仓壳体51，具有彼此相对的顶板511和底板512；至少两个层叠设置在夹仓壳体51内的仓体52，该至少两个仓体52位于顶板511和底板512之间，每个仓体52内设置有结扎夹53和/或推夹组件54。进一步地，夹仓装置5构造 为：当位于底层的仓体52被外力推动沿仓体52的纵长方向移动以与上层的仓体52错开时，上层的仓体52向下移动一层，从而在外力的推动下，层叠设置的至少两个仓体52展开且展开后相邻两个仓体52不再彼此层叠。进一步地，至少两个仓体52包括收纳结扎夹53的第一仓体523和收纳推夹组件54的第二仓体524，展开后第一仓体523位于第二仓体524的前侧，且展开后，推夹组件54在外力的作用下推动结扎夹53向前运动以实现送夹。
例如，至少两个仓体52在展开之后位于同一层。例如，至少两个仓体52在展开之后经由夹仓壳体1的开口513依次进入击发套管4。
例如，由于展开后第一仓体523位于第二仓体524的前侧，因此在展开前第一仓体523层叠设置在第二仓体524的下方，即在展开前第一仓体523比第二仓体524更靠近底板512。
例如，仓体52的纵长方向为从仓体52的后端至前端的方向。例如，仓体52的纵长方向平行于击发套管4的长度方向。
例如，参见图5，夹仓装置5还包括设置在夹仓壳体51内的弹性组件55，弹性组件55位于层叠设置的至少两个仓体52与夹仓壳体51的顶板511之间，弹性组件55包括压板551及设置在压板551与夹仓壳体51的顶板511之间且处于压缩状态的弹性件552，当位于底层的仓体52被外力推动沿仓体52的纵长方向移动以与上层仓体52错开后，弹性件552在其弹力作用下推动压板551以推动上层设置的仓体52下移一层。例如，该弹性件552为弹簧，诚然，该弹性件552也可为其他，只要达到上述效果即可。
例如，参见图5，夹仓壳体51的顶板511设置有容纳槽553，弹性件552的靠近顶板511的端部插入容纳槽553并连接到顶板511。由于弹性件552的靠近顶板511的端部插入容纳槽553，容纳槽553可以引导弹性件552竖直向下运动，以利于弹性件552推动压板551向下运动。
例如，如图5所示，容纳槽553为自顶板551朝向底板512延伸的筒状槽，但是本公开实施例不局限于此，容纳槽553也可以为其他结构，只要达到上述效果即可。
例如，参见图5，夹仓壳体51的前端具有开口513，当位于底层的仓体52被外力推动沿所述仓体52的纵长方向移动以与上层的仓体52错开时，位于底层的所述仓体52经所述开口513至少部分运动至所述夹仓壳体51之外。 例如，位于底层的所述仓体52经所述开口513至少部分运动至所述夹仓壳体51之外并进入击发套管4。
例如，参见图5至图12，每个仓体52包括：彼此相对设置的仓板521和齿条板522；以及挡板5211，设置在仓板521和齿条板522之间并连接仓板521和齿条板522。例如，进一步地，每个仓体52包括：位于仓体52的前端的开口部，以供结扎夹53和/或推夹组件54移出至仓体52之外；以及位于仓体52的后端的开口部，以供结扎夹53和/或推夹组件54移入至仓体之52内。例如，进一步地，齿条板522的远离仓板521的一侧设置有齿条，夹仓壳体51的底板512具有开口槽5121，开口槽5121露出齿条板522的齿条，外力施加至所述齿条以推动齿条板522移动，从而带动仓体52移动。
例如，为了生产及装配的便捷性，挡板5211与仓板521和齿条板522中的至少之一可拆卸连接。
例如，每个仓体52具有与外力相配合的齿条板522，外力推动齿条板522移动以推动仓体52移动。仓体52可一体设置，也可分体设置。例如，在本公开实施例中，为了生产及装配的便捷性，仓体52为分体式设置。仓体52还包括盖设在齿条板522上以与齿条板522形成腔体的仓板521。于仓体52的纵长方向上，仓体52的前后端具有开口部，以供结扎夹53和/或推夹组件54移出至该仓体52外进入与该仓体52相邻的仓体52内。仓板521连接自仓板521两侧向齿条板522延伸的挡板5211(例如，挡板5211与仓板521一体成型)，齿条板522上设置有与挡板5211卡持的凸块5221。例如，在本公开实施例中，齿条板522上设置有四个凸块5221，四个凸块5221分别两两设置在齿条板522的两侧边上。齿条板522的宽度等于两挡板5211之间的距离，沿仓体52的宽度方向上，两个凸块5221正好与挡板5211卡持，从而将实现齿条板522与挡板5211的连接。
例如，至少两个仓体52构造为：展开后相邻两个仓体52的相邻的端部彼此连接。这样一来，展开后相邻两个仓体52彼此连接，有利于结扎夹53和推夹片543向前运动。例如，展开后相邻两个仓体52的相邻的端部分别设置有第一挂钩5212及与第一挂钩5212相配合的第一卡槽5213，从而展开后相邻两个仓体52通过第一挂钩5212与第一卡槽5213卡合以实现连接。
例如，对于相邻的两个仓体52，可以于在前的仓体52的后端设置第一 挂钩5212而于在后的仓体52的前端设置第一卡槽5213；在此情形下，第一挂钩5212向上弯曲，第一卡槽5213的开口向下；当在前的仓体52与在后的仓体52错开而使得在后的仓体52下降时，第一卡槽5213与第一挂钩5212卡和。例如，对于相邻的两个仓体52，可以于在前的仓体52的后端设置第一卡槽5213而于在后的仓体52的前端设置第一挂钩5212；在此情形下，第一卡槽5213的开口向上，第一挂钩5212向下弯曲；当在前的仓体52与在后的仓体52错开而使得在后的仓体52下降时，第一卡槽5213与第一挂钩5212卡和。
例如，第一挂钩5212和第一卡槽5213设置在仓体52的挡板5211上。
例如，仓体52的两端分别设置有第一挂钩5212及与第一挂钩5212相配合的第一卡槽5213，第一挂钩5212及第一卡槽5213分别设置在挡板5211的两端，相邻的两个仓体52在外力的推移下错位后通过第一挂钩5212与第一卡槽5213卡合以实现连接。例如，位于最底层的仓体52(也就是，展开后位于最前侧的仓体52)只在其后端设置有第一挂钩5212或第一卡槽5213，位于最顶层的仓体52(也就是，展开后位于最后侧的仓体52)只在其前端设置有第一卡槽5213或第一挂钩5212。相邻的两个仓体52的第一挂钩5212与第一卡槽5213相邻设置，即前侧的仓体52的第一挂钩5212与后侧的仓体52的第一卡槽5213相邻设置或者前侧的仓体52的第一卡槽5213与后侧的仓体52的第一挂钩5212相邻设置。为了方便结扎夹53与推夹组件54在仓体内的移动，第一卡槽5213与第一挂钩5212设置在仓体52的同一挡板5211上。
例如，推夹组件54包括于外力作用下相对仓体52可前后移动的移动件及被移动件推动以相对仓体52向前移动的推夹片543，相邻两个移动件在展开后彼此连接，移动件上设置有第一棘齿5422，推夹片543上设置有至少两个与第一棘齿5422抵持的第一长槽口5431。例如，至少两个第一长槽口5431包括在前的第一长槽口5431和在后的第一长槽口5431，第一棘齿5422首先抵持在在前的第一长槽口5431上，移动件向前移动，第一棘齿5422推动推夹片543向前运动；然后，移动件向后移动使得第一棘齿5422抵持在在后的第一长槽口5431上；然后，移动件再向前移动，第一棘齿5422推动推夹片543向前运动。
例如，移动件可以一体设置，也可以分体设置。例如，在本公开实施例中，为了方便加工制造，移动件包括层叠设置的第一移动部541及第二移动部542，第二移动部542比第一移动部541更靠近推夹片543，第二移动部542固定至第一移动部541，第一棘齿5422设置在第二移动部542上，推夹片543设置在第二移动部542的上方。例如，第一移动部541上设置有沿第一移动部541宽度方向开设的开口5411，第二移动部542上设置有与开口5411卡持的卡件5421，将卡件5421卡入开口5411以实现第二移动部542固定至第一移动部541。
例如，展开后相邻两个移动件的第一移动部541的相邻的端部分别设置第二挂钩5412及与第二挂钩5412相配合的第二凹槽5413，从而展开后相邻两个移动件通过第二挂钩5412与第二凹槽5413卡合以实现连接。
例如，在第一移动部541的要设置第二凹槽5413的端部，在第一移动部541的侧面形成第二凹槽5413；第一移动部541的设置有第二挂钩5412的端部伸出仓体52外，以与相邻的第一移动部541的第二凹槽5413卡和，从而使得相邻两个第一移动部541更好的连接。第一移动部541上设置有第二挂钩5412及与第二挂钩5412相配合的第二凹槽5413，第二挂钩5412及第二凹槽5413分别设置在第一移动部541的两侧。相邻的两个仓体52在外力的推移下错位后通过第一挂钩5212与第一卡槽5213卡合以实现连接时，相邻的两个推夹组件54通过设置在第一移动部541两侧的第二挂钩5412及第二凹槽5413实现连接。
例如，对于相邻的两个第一移动部541，可以于在前的第一移动部541的后端设置第二挂钩5412而于在后的第一移动部541的前端设置第二凹槽5413；在此情形下，第二挂钩5412向上弯曲；当在前的仓体52与在后的仓体52错开而使得在后的仓体52下降时，第二挂钩5412与第二凹槽5413卡和。例如，对于相邻的两个第一移动部541，可以于在前的第一移动部541的后端设置第二凹槽5413而于在后的第一移动部541的前端设置第二挂钩5412；在此情形下，第二挂钩5412向下弯曲；当在前的仓体52与在后的仓体52错开而使得在后的仓体52下降时，第二凹槽5413与第二挂钩5412卡和。
例如，仓体52与推夹片543之间设置有止位结构，止位结构包括第二棘 齿5214以及与第一长槽口5431平行且与第一长槽口5431错位设置的第二长槽口5432。例如，第一长槽口5431与第二长槽口5432均与推夹片543的长度方向平行。例如，错位设置是指第一长槽口5431与第二长槽口5432无重叠部分；具体而言，在垂直于推夹片543的方向上，第一长槽口5431与第二长槽口5432无重叠部分；并且在推夹片543的宽度方向上，第一长槽口5431与第二长槽口5432无重叠部分。第二长槽口5432设置在仓体52(例如，仓体52的仓板521)和推夹片543其中之一上，第二棘齿5214设置在仓体52(例如，仓体52的仓板521)和推夹片543另一个上。例如，第一棘齿5422与第二棘齿5214径向设置。具体而言，当第二长槽口5432设置在推夹片543上、第二棘齿5214设置在仓体52上时，第一棘齿5422自移动件向上且向前延伸，第二棘齿5214自仓体52(例如，仓体52的仓板521)向下且向前延伸；当第二长槽口5432设置在仓体52上、第二棘齿5214设置在推夹片543上时，第一棘齿5422自移动件向上且向前延伸，第二棘齿5214自推夹片543向上且向后延伸。于结扎夹53移动方向上，相邻两个第一长槽口5431分别为前侧第一长槽口与后侧第一长槽口，前侧第一长槽口及后侧第一长槽口皆具有与第一棘齿5422抵持的抵持面，移动件在外力作用下前移以推动推夹片543前移，第一棘齿5422与前侧第一长槽口的抵持面抵持以推动推夹片543前移；移动件在外力作用下后移，推夹片543由于第二长槽口5432与第二棘齿5214的配合与仓体52保持固定；第一棘齿5422后移至后侧第一长槽口且与其抵持面抵持。
本公开实施例中的推夹组件54可只设置有一个，也可设置有多个。在本实施例中，根据击发套管4的长度，例如推夹组件54设置有三个。诚然，在本公开实施例中，推夹组件54的个数可以为其他，根据实际情况而定，在此不做具体限定。
为了更好的区别三个推夹组件54，三个推夹组件54分别称为第一推夹组件544、第二推夹组件545及第三推夹组件546，第一推夹组件544直接与结扎夹53接触以推动结扎夹53前移，第二推夹组件545与第一推夹组件544连接，第三推夹组件546与第二推夹组件545连接。第一推夹组件544、第二推夹组件545及第三推夹组件546结构大致相同，仅第一移动部541及推夹片543的结构略有不同。第一推夹组件544的第一移动部541只有远离结 扎夹53的一端设置有第二凹槽5413或第二挂钩5412，第一推夹组件544的推夹片543的靠近结扎夹的端部设置有与结扎夹53抵持的突伸块，以使得推夹片543在第一移动部541及第二移动部542的推移下更好的推动结扎夹53前移。
例如，夹仓壳体51内还设置有与推夹组件54连接的推杆56。例如，推杆56设置在位于最后侧的推夹组件的后侧且与位于最后侧的推夹组件54连接；位于最后侧的推夹组件的第一移动部541的前端设置有第二挂钩5412或第二凹槽5413，后端设置有槽口5414，推杆56的端部设置有与槽口5414卡持的突出部561。例如，在本公开实施例中，该推杆56与第三推夹组件546连接；第三推夹组件546的第一移动部541与推杆56连接，其第一移动部541的前端设置有第二挂钩5412或第二凹槽5413，后端设置有槽口5414，推杆56的端部设置有与槽口5414卡持的突出部561。第二推夹组件545的第一移动部541的一端设置有第二挂钩5412，另一端设置有第二凹槽5413，以将第一推夹组件544与第三推夹组件546连接。
例如，在本公开实施例中，第一仓体523与结扎夹53形成第一夹仓组件527，展开后位于最前侧的第一夹仓组件527还包括夹钳59，夹钳59设置在该最前侧的第一夹仓组件527的前侧且与该最前侧的第一夹仓组件527的第一仓体523连接。例如，在第一仓体523内仅设置结扎夹53，而不设置推夹组件54。在本公开实施例中，例如第一夹仓组件527仅设置一个，但是本公开实施例不对第一夹仓组件527的个数作具体限定。
例如，第二仓体524内仅设置有推夹组件54，该推夹组件54为第二推夹组件545，第二仓体524与第二推夹组件545形成第二夹仓组件528。
例如，至少两个仓体52还包括设置在第一仓体523与第二仓体524之间的第三仓体525，展开后第三仓体525位于第一仓体523与第二仓体524之间且连接第一仓体523及第二仓体524，第三仓体525内设置有结扎夹53和推夹组件54，第三仓体525与结扎夹53、推夹组件54形成第三夹仓组件529，该推夹组件54为第一推夹组件544。

例如，根据本公开实施例的外科手术器械还包括控制驱动装置2的第一开关102及第二开关103。例如，为了布局的合理性及外观上的美观性，握持部100包括握持外壳101，握持外壳101形成有收容腔，驱动装置2至少部分设置在所述收容腔内。握持部100还包括设置在收容腔内且与驱动装置2电连接的控制电路、设置在握持外壳101上且耦合至控制电路的第一开关102及第二开关103，其中，第一开关102用于控制驱动装置2以驱动夹仓装置5实现送夹动作，第二开关103用于控制驱动装置2以使得击发施力件3驱动击发套管4相较于夹仓装置5移动以实现送夹，结扎目标组织。诚然，驱动装置2、控制电路、第一开关102及第二开关103也可至少部分设置在工作部200上，根据实际情况而定，在此不做具体限定。
例如，驱动装置2包括电机21、与电机21连接的锥齿轮22、第一齿轮24、第二齿轮25、第三齿轮27、击发轴31、齿条组件23以及切换按钮6，其中，第一齿轮24与第三齿轮27共轴。例如，驱动装置2构造为：不拨切换开关6且按下第一按钮102时，电机21提供动力且将动力传动至锥齿轮22，锥齿轮22将动力传动至与其连接的第三齿轮27，使第三齿轮27逆时针转动，第三齿轮27逆时针转动带动与其共轴的第一齿轮24逆时针转动，第一齿轮24逆时针转动带动底层的仓体52往前运动，以使得至少两个仓体展开。例如，第一齿轮24与底层的仓体52的齿条板522啮合以带动底层的仓体52往前运动。例如，驱动装置2构造为：拨切换开关6且按下第一按钮102时，电机21提供动力并将动力传动至锥齿轮22，锥齿轮22将动力传动至与其连接的击发轴31以使得击发轴31旋转，旋转的击发轴31带动与其连接的齿条组件23后退，齿条组件23后退以与第二齿轮25啮合并带动第二齿轮25逆时针转动，逆时针旋转的第二齿轮25推动推夹组件54往前运动，推 夹组件54推动结扎夹53往前运动，以实现送夹。例如，逆时针旋转的第二齿轮25推动推杆56往前运动，推杆56推动推夹组件54的推夹片543往前运动，推夹片543将结扎夹53送入夹钳59，以实现送夹。例如，驱动装置2构造为：拨切换开关6且按下第二按钮103时，电机21提供动力并将动力传动至锥齿轮22，锥齿轮22将动力传动至与其连接的击发轴31，击发轴31旋转且旋转方向与上述送夹过程相反，反方向旋转的击发轴31带动齿条组件23向前运动，向前运动的齿条组件23带动与其啮合(在上述送夹过程中已经啮合)的第二齿轮25顺时针旋转，第二齿轮25顺时针旋转带动推夹组件54后退，齿条组件23继续向前运动而与第二齿轮25分离，齿条组件23继续向前运动将动力传动至击发套管4以使击发套管4击发，结扎夹被夹到目标组织。例如，第二齿轮25顺时针旋转带动推杆56后退，从而推杆56带动推夹组件54的推夹片543后退。例如，击发套管4击发，以使夹钳59闭合，从而结扎夹53被夹到目标组织。
例如，于仓体52的移动方向上，第一齿轮24设置在第二齿轮25的前方。
例如，外壳1上设置与击发轴31连接的切换按钮6，往左拨动切换按钮6使得齿条组件23与第二齿轮25啮合。例如，为了更好的与第一齿轮24连接，仓体52的齿条板522的朝向第一齿轮24的一侧设置有与第一齿轮24啮合的齿条。例如，电机21转动驱动锥齿轮22转动以带动齿条组件23后退，齿条组件23后退直至与第二齿轮25啮合进而带动第二齿轮25逆时针转动，第二齿轮25逆时针转动带动第一推块57朝向夹钳59移动以带动推杆56前移，推杆56伸入至腔体内以推动移动件移动，移动件带动推夹片543向前移动进而驱动结扎夹53前移。例如，电机21转动驱动锥齿轮22转动以带动齿条组件23前移，进而带动第二齿轮25顺时针转动，第二齿轮25顺时针转动带动第一推块57后移以带动推杆56后移，推杆56带动移动件后移，由于第一棘齿5422与第一长槽口5431的配合，第一棘齿5422在后退过程中无法抵持第一长槽口5431，所以在移动件后移时，推夹片543保持不动；齿条组件23继续前移以使得击发套管4前移直至使得夹钳59闭合完成击发。
例如，重复执行上述送夹过程和击发过程，以实现连续送夹。
例如，当夹仓装置中的夹子全部用完后，更换新的夹仓装置，使新的夹仓装置中的至少两个仓体展开，然后进行送夹和击发。
根据本公开实施例，通过将至少两个仓体52层叠设置在夹仓壳体51内，每个仓体52内设置有结扎夹53和/或推夹组件54，位于底层仓体52被外力推动沿仓体52的纵长方向移动以与上层仓体52错开时，上层仓体52向下移动一层；这样一来，至少两个层叠设置的仓体52被外力推动以展开；设置有推夹组件54的仓体52设置在设置有结扎夹53的仓体52后方以推动结扎夹53前移实现送夹，使得夹仓装置5的整体结构变得小巧而轻便，在实现连续送夹的同时，还有助于减小储藏器械的压力。
以上所述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，都应当认为落入本公开的保护范围。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
