在该实施例中，凸块61与钉带本体42也可以是分体设置的。如图6～11所示，两排所述吻合钉41之间设置有一连杆6，所述连杆6的顶部设置有所述凸块61即所述凸块61设于所述连杆6靠近钉仓组件的钉仓面的一侧。所述凸块61从所述钉带本体42的一侧边向上伸出。为了更清楚地示出钉带4和连杆6的配合结构，在图7中省去了最外侧的一个限位件5。进一步地，所述钉带本体42与各个所述凸块61对应的位置分别开设有用于容纳所述凸块61的凸块容纳口421。凸块61从凸块容纳口421中穿出而突出于所述钉仓组件面。连杆6也可以和限位件5共同限定吻合钉41的容纳空间和出钉方向。吻合钉41在被击发时，两侧同时受到限位件5的侧面引导和连杆6的侧面引导，可以顺畅地从钉带本体42表面的开口中穿出，而不会发生偏离轴向方向的偏摆而造成卡钉现象。其中，限位件5和连杆6优选采用比较硬的金属，例如不锈钢等制成。In this embodiment, the
由于现有技术中采用单个吻合钉的结构中，每个吻合钉是单独安装在一个钉孔里面的，其不会存在吻合钉的定位问题。而在采用钉带4的结构中，由于不再设置单独的每个钉孔，因此，需要进一步解决钉带4中吻合钉41的定位问题。如图8所示，在该实施例中，连杆6还可以与限位件5一起限定吻合钉41在钉仓组件中的位置。即每排吻合钉41设置于其一侧的限位件5和一侧的连杆6之间。每两个相邻的连杆6和限位件5一起限定了一个沿吻合器轴向方向的吻合钉容纳空间。吻合钉41的上下运动只能限定在此吻合钉容纳空间中，既不会向限位件5的一侧偏离，也不会向连杆6的一侧偏离。在吻合钉41向钉仓组件面运动而与钉带本体42脱离的过程中，吻合钉41的运动方向也被连杆6和限位件5而限定，可以准确地定位到组织上需要吻合的位置。Since in the prior art structure using a single staple, each staple is individually installed in a staple hole, there is no problem of staple positioning. However, in the structure using the
因此，该实施例不仅解决了手术时钉带4中吻合钉41方便脱离的问题，还进一步解决了钉带4中吻合钉41定位的问题。Therefore, this embodiment not only solves the problem of convenient disengagement of the
在该实施例中，所述凸块61的远端侧面611为从远端侧向近端侧逐渐上升的斜面，且所述远端侧面611整体呈顺滑设置，即远端侧面611的顶端平滑过渡至凸块61的顶面，例如在远端侧面611和凸块61的顶面之间设有顺滑的倒角，以防止在吻合器闭合时，锋利的边角对组织造成损伤。所述凸块61与所述远端侧面611相对的近端侧面613，即与所述连接端412相邻的近端侧面613，也设为从远端侧向近端侧逐渐上升的斜面，以提高与连接端412的配合效果。进一步地，近端侧面613可以形成为刃口，以加强对连接端412的剪切效果。在一优选的实施方式中，在初始状态下，所述连接端412与所述近端侧面613之间设有一定的间隔，以保证所述吻合钉41在旋转的过程中的形变，不会受到所述近端侧面613的阻挡，并且保证所述吻合钉未完全成型之前，不与钉带分离。In this embodiment, the
