具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实 施例，都属于本公开保护的范围。
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”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。
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，增加了手术时间，增大了患者出血量，延长了患者恢复时间，也增加了患者的经济压力。于是，能够连续送夹的施夹钳应运而生，但是能够连续送夹的夹仓装置通常体积较大，从而增加了储藏医疗器械的压力。
请参见图1至图11，本公开的实施例提供一种外科手术器械，包括握持部200及与握持部200连接的工作部100，握持部200和工作部100包括驱动装置2。工作部100包括：限定内腔11的外壳1；设置在外壳1内且与驱动装置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；及由驱动装置2驱动的夹仓装置5。外壳1上开设有开口12，夹仓装置5通过开口12以经过内腔11进而插入至击发套管4内。将夹仓装置5整体与工作部100可拆卸设置，当夹仓装置5内的结扎夹524用完后，可从开口12处将夹仓装置5取出以更换新的夹仓装置5，实现握持部200及工作部100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100可拆卸设置，从而可以将夹仓装置5和工作部100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。
需要说明的是，握持部200和工作部100包括驱动装置2包括以下情形：整个驱动装置2设置于握持部200；或者，整个驱动装置2设置于工作部100；或者，驱动装置2的一部分设置于握持部200而驱动装置2的另一部分设置于工作部100。
例如，击发套管4设置在外壳1所限定的内腔11之外。例如，根据需要， 击发套管4上设置有拨盘，用于调节施夹角度。
本公开实施例提供一种夹仓装置。请具体参见图3至图10，夹仓装置5包括：具有腔体511的夹仓壳体51、夹仓组件52、以及推动夹仓组件52实现送夹的推夹组件53，推夹组件53包括推夹片531和推片523。腔体511内设置有第一弹性件54及致使第一弹性件54处于被压缩状态的制动件55，第一弹性件54可沿腔体511的纵长方向舒展；当第一弹性件54处于被压缩状态时，夹仓组件52和推片523收容在腔体511内，并且沿腔体511的纵长方向，制动件55位于第一弹性件54和夹仓组件52之间并位于第一弹性件54与推片523之间；当制动件55作用于第一弹性件54上的力撤销时，第一弹性件54在其弹力的作用下推动夹仓组件52和推片523从腔体511内移出，从而第一弹性件54处于舒展状态并且推片523与推夹片531连接。
例如，当第一弹性件54处于被压缩状态时，夹仓组件52和推片523收容在腔体511内是指：夹仓组件52的至少部分或全部收容在腔体511内，并且推片523的至少部分或全部收容在腔体511内。为了夹仓装置5更加小巧化，夹仓组件52全部收容在腔体511内，并且推片523全部收容在腔体511内。
例如，可以在制动件55上施加外力，以使得制动件55作用于第一弹性件54上的力撤销。
例如，当夹仓装置5安装至工作部100时，第一弹性件54因为制动件55的作用处于被压缩状态。
例如，推夹片531至少部分收容在腔体511内，并且推夹片531的远离如下所述的夹钳522的端部突出于腔体511。例如，推夹片531的两端皆设置在腔体511外，其余部分设置在腔体511内。
例如，沿腔体511的纵长方向，制动件55设置在第一弹性件54及夹仓组件52之间；夹仓壳体51上设置有第一通孔512及第二通孔513，制动件55与第一通孔512卡持以使得第一弹性件54处于被压缩状态，此时夹仓组件52被收容在腔体511内；制动件55与第二通孔513卡持以使得第一弹性件54处于舒展状态，此时夹仓组件52被推移出腔体511外。
例如，参见图12，制动件55包括具有容置孔的滑块550、设置在滑块的容置孔内的第三弹性件551及设置在第三弹性件551两端的卡件552；当第 一弹性件54处于压缩状态，设置在第三弹性件551两端的卡件552在第三弹性件551的弹力作用下与第一通孔512卡持；当外力作用于卡件552，卡件552与第一通孔512脱离，从而第一弹性件54在其弹力的作用下推动夹仓组件52和推片523移动；当第一弹性件54处于舒展状态，设置在第三弹性件551两端的卡件552在第三弹性件551的弹力作用下与第二通孔513卡持。
例如，卡件552的远离第三弹性件551的端面为弧面，有利于卡件与第一通孔512和第二通孔513卡持。例如，卡件552为球体。
例如，夹仓组件52包括结扎夹524以及用以放置结扎夹524的夹子托盘521。例如，夹仓装置5还包括夹钳522，设置在夹仓组件52的远离第一弹性件55的一侧并与夹子托盘521连接。夹钳522与夹子托盘521之间的连接方式为常规方式，在此不做赘述。例如，当第一弹性件54处于被压缩状态时，夹仓组件52、推片523以及推夹片531层叠设置并且推片523夹设在夹仓组件52和推夹片531之间；推片523靠近推夹片531的一侧设置有凸块525，当第一弹性件54处于舒展状态时，凸块525与推夹片531卡持以使得推片523与推夹片531连接。例如，通过凸块525和卡槽5315卡接，以使得推夹片531与推片523连接。例如，推片523上设置有若干个朝向夹钳522的棘齿，棘齿抵持结扎夹524，从而在第一弹性件54处于舒展状态时，在推夹片531的驱动下推片523的棘齿推动结扎夹524朝向夹钳522移动。
例如，在第一弹性件54处于压缩状态时以及处于舒展状态时，推片523均覆盖夹子托盘521，并且推片523上的棘齿面向放置在夹子托盘521中的结扎夹524。
例如，如上所述，当第一弹性件54处于被压缩状态时，夹仓组件52、推片523以及推夹片531层叠设置并且推片523夹设在夹仓组件52和推夹片531之间，在此情形下，如图5所示，推片523和夹仓组件52层叠于推夹片531下方；然而本公开实施例不局限于此，推片523和夹仓组件52也可以层叠于推夹片531上方。需要说明的是，不论推片523和夹仓组件52层叠于推夹片531下方还是上方，推片523均夹设在夹仓组件52和推夹片531之间。
例如，当第一弹性件54处于被压缩状态时，夹钳522自腔体511露出。
例如，当第一弹性件54处于舒展状态时，推片523上的凸块525与推夹片531卡持。例如，推夹片531上设置有供凸块525滑动的长槽5311(例如， 凸块525以突出于推夹片531的状态在长槽5311中滑动)，并且沿腔体511的纵长方向，长槽5311具有远离夹钳522的第一端和靠近夹钳522的第二端；当第一弹性件54处于被压缩状态时，凸块525处于第一端；当第一弹性件54处于舒展状态时，凸块525滑动至长槽5311的第二端以与推夹片531卡持。例如，长槽5311上至少部分覆盖有与推夹片531连接的弹片5312，弹片5312与长槽5311的第二端围设形成有用以与凸块525相配合的卡槽5315。例如，弹片5312的朝向长槽5311的第二端的边缘为弧形，该弧形朝向远离长槽5311的第二端的方向凹陷。如图5所示，推片523和夹仓组件52层叠于推夹片531下方，而弹片5312覆盖在推夹片531上方；也就是，弹片5312与推片523和夹仓组件52位于推夹片531的相反侧。例如，弹片5312具有朝向推夹片531设置的内表面5313，内表面5313为斜面5314，斜面5314倾斜设置为使得斜面5314的靠近夹钳522的一端比斜面5314的远离夹钳522的一端更靠近推夹片531，凸块525沿斜面5314滑移至卡槽5315并与卡槽5315卡持。例如，在图5中，推片523和夹仓组件52层叠于推夹片531下方，在此情形下，斜面5314自靠近夹钳522的一端向远离夹钳522的一端向上倾斜设置。通过设置斜面5314，可以更好地引导凸块525进入卡槽5315。
例如，弹片5312包括第一片状部5316、折弯部5317和第二片状部5318，折弯部5317连接在第一片状部5316和第二片状部5318之间，内表面5313设置在折弯部5317上，第二片状部5318比第一片状部5316靠近夹钳522并且第一片状部5316与推夹片531之间的高度差大于第二片状部5318与推夹片531之间的高度差。例如，第一片状部5316与推片523之间的高度差略大于凸块525的厚度，第二片状部5318与推片之间的高度差小于凸块525的厚度。例如，卡槽5315由第二片状部5318的末端边缘与长槽5311的第二端围设形成，该第二片状部5318的末端边缘为内凹的弧形。
例如，也可在凸块525上设置有斜面5314；在此情形下，凸块525的远离推片523的表面为斜面5314，斜面5314倾斜设置为使得斜面5314的靠近夹钳522的一端比斜面5314的远离夹钳522的一端更靠近推夹片531。例如，在图5中，推片523和夹仓组件52层叠于推夹片531下方，在此情形下，斜面5314自靠近夹钳522的一端向远离夹钳522的一端向上倾斜设置。通过设置斜面5314，可以更好地引导凸块525进入卡槽5315。
例如，推夹组件53还包括伸入至腔体511内且与第一弹性件54连接的推杆532以及设置在推杆532上且可相对于推杆532滑动的推块533，推块533位于腔体511之外且推夹片531与推块533连接。例如，推块533上设置有与驱动装置2啮合的齿条；进一步地，推块533上设置有与驱动装置2的小齿轮24啮合的齿条。例如，推夹组件53还包括套设在推杆532上的第二弹性件534，第二弹性件534夹持在夹仓壳体51与推块533之间。第二弹性件534为缓冲作用，防止推块533与夹仓壳体51之间发生刚性冲击以保护推杆532、推块533及推夹片531。例如，推杆532的端部(即推杆532的远离第一弹性件54的端部)上还设置有与开口12卡持的止位件535及拉块537，拉块537比止位件535远离推杆532。止位件535用以防止在驱动装置2驱动推夹组件53时夹仓装置5全部进入腔体511内从而致使整个装置无法工作，拉块537用以在夹仓组件52内的结扎夹524全部用完时，可通过拉块537将整个夹仓装置5拉出以替换。
例如，驱动装置2包括电机21、与电机21连接的锥齿轮22、与锥齿轮22啮合的齿条组件23及构造为可与齿条组件23啮合的小齿轮24，齿条组件23包括与锥齿轮22啮合的螺杆231及与螺杆231连接的第一齿条232，第一齿条232连接击发施力件3，小齿轮24构造为可与第一齿条232啮合。承上述，为了与驱动装置2更好的连接，推块533上设置有与驱动装置2的齿轮啮合的齿条536，该齿条与小齿轮24啮合。本公开实施例的外科手术器械送夹及击发过程为：电机21转动驱动锥齿轮22转动以带动螺杆231后退进而带动第一齿条232后退，第一齿条232后退直至与小齿轮24啮合进而带动小齿轮24顺时针旋转，小齿轮24顺时针旋转进而推动推块533在推杆532上向前移动，推块533向前移动从而驱动推夹片531送夹；电机21转动驱动锥齿轮22转动以带动螺杆231前移进而带动第一齿条232前移，第一齿条232前移与小齿轮14分离，第一齿条232继续前移带动击发施力件3前移，击发施力件3前移进而带动击发套管4相较于夹仓装置5前移以使得夹钳522闭合完成击发动作，结扎夹例如被施加到目标组织上。
请结合图2及图3，击发施力件3包括与第一齿条232连接的击发块31及用以连接击发块31与击发套管4的连接块32，击发套管4与外壳1滑动连接，击发套管4具有向外翻折设置的裙边41，该裙边41与连接块32抵持 连接。驱动装置2驱动击发块31向前移动以驱动连接块32移动进而驱动裙边41以使得整个击发套管4移动。外壳1上设置有凸起，击发套管4上设置有沿凸起滑动的滑槽42。击发套管4上还设置有开孔43，当第一弹性件54处于被压缩状态时，制动件55位于开孔43处，外力通过开孔43施加在制动件55上以使得制动件55作用于第一弹性件54上的力撤销。该开孔43的位置与第一通孔512的位置相同，制动件55穿过第一通孔512与开孔43卡持，施加外力在开孔43及第一通孔512以使得制动件55滑动至第二通孔513处。外力可以直接通过人体手部施加，亦可通过外部器件施加，例如镊子等，在此不做具体限定，根据实际情况而定。例如，亦可在击发套管4上与第一通孔512位置对应处设置有小突起，当第一通孔512达到小突起处，小突起将制动件55向内挤压以使得制动件55从第一通孔512处滑移至第二通孔513处并与第二通孔513卡持，在此不做限定。
为了布局的合理性及外观上的美观性，握持部200包括握持外壳201，握持外壳201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200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201上且耦合至控制电路的第一开关202及第二开关203，其中，第一开关202用于驱动夹仓装置5实现送夹动作，第二开关203用于驱动击发施力件3进而驱动击发套管4相较于夹仓装置5移动以结扎目标组织。诚然，驱动装置2、控制电路、第一开关202及第二开关203也可至少部分设置在工作部100上，根据实际情况而定，在此不做具体限定。
在本公开实施例中，上述第一弹性件54、第二弹性件534及第三弹性件551皆为弹簧。诚然，在其他实施例中，第一弹性件54、第二弹性件534及第三弹性件551也可为其他具有弹性的部件，根据实际情况而定，在此不做具体限定。
根据本公开的实施例，夹仓装置包括第一弹性件54和制动件55，第一弹性件54在制动件55的作用下将夹仓组件52至少部分(优选地，全部)收容在腔体511内，当制动件55作用于第一弹性件54上的力撤销，第一弹性件54在其弹力作用下将夹仓组件52推移出腔体511外，然后再进行送夹动作，在实现连续送夹的同时，夹仓装置5的整体结构变得小巧而轻便，从而有助于减小储藏医疗器械的压力。
以上所述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，都应当认为是本公开的保护范围。
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。
