具体实施方式
为了使本技术领域的人员更好地理解本公开方案，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分的实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本公开保护的范围。
下面通过具体实施例，分别进行详细的说明。
如图1-12所示，一种可脱式吻合夹，包括夹子框架1和连接于所述夹子框架1的第一咬合件2和第二咬合件3，其中，第一咬合件2和/或第二咬合件3与所述夹子框架1是可拆卸连接。将至少一个咬合件与夹子框架设计成可拆卸式，在取出吻合夹时，可先将可拆卸的咬合件与夹子框架分离后再移除，能够安全、简便地将吻合夹取出。在实际应用过程中，本领域技术人员可选择将所有的咬合件都设置成与夹子框架可拆卸连接，也可选择其中一个或多个设置成与夹子框架可拆卸连接；此外，虽然本实施例是弧形吻合夹，本领域人员应当理解，可拆卸的咬合件也可用于其他形状的吻合夹，例如3个及以上的咬合件异形吻合夹。
本实施例中，所述夹子框架1是封闭式外框架。该方案中，采用封闭式外框架，能够在现有的单体式吻合夹基础上，不改变原有单体式吻合夹的外形结构，只需将其内部的咬合件设计成可拆卸式即可，能够保证本方案的可脱式吻合夹与现有的单体式吻合夹具有相同的外框结构，从而不需要单独设计施夹帽，无论从生产、设计等角度均具有一定的优势；此外，本方案的设计，还能够利用现有的单体式吻合夹，在现有单体式吻合夹的基础上进行加工/改型，只需将现有单体式吻合夹内部的咬合件设置成分离、拆卸式即可。
本实施例中，第一咬合件2和第二咬合件3是连接于所述封闭式外框架内部的齿片，所述齿片上具有至少一个齿4。
本实施例中，所述封闭式外框架包括上臂5、左侧臂6、下臂7和右侧臂8，所述上臂5、左侧臂6、下臂7和右侧臂8依次连接形成所述封闭式外框架。
本实施例中，第一咬合件2和第二咬合件3分别连接于所述上臂5和下臂7，其中所述第一咬合件2与所述上臂5可拆卸连接和/或所述第二咬合件3与所述下臂7可拆卸连接。
本实施例中，第一咬合件2和/或第二咬合件3包括至少一个固定槽，所述夹子框架1至少包括与所述固定槽插接配合的凸起。通过槽和凸起的卡槽式配合，实现咬合件与夹子框架的可拆卸连接。当然，本领域技术人员应当理解，其他可拆卸的机械连接也可用于本方案，例如夹持连接等等。
本实施例中，所述固定槽包括第一固定槽9和第二固定槽10，所述第一固定槽9和第二固定槽10设置于咬合件2(3)的相反侧面，所述夹子框架1包括与第一固定槽9和第二固定槽10插接配合的第一凸起11和第二凸起12。通过将第一固定槽9和第二固定槽10设置于咬合件2(3)的相反侧面，能够在咬合件2(3)的两侧分别进行固定，例如本实施例中，第一固定槽9负责咬合件2(3)的后部的固定，第二固定槽10负责咬合件2(3)前部的固定，如此设置，能够保证在吻合夹被激发后夹紧组织的瞬间，咬合件2(3)不发生位移。

本实施例中，所述第二固定槽10和第三固定槽13分别位于所述第一固定槽9的两侧，其中所述第二固定槽10和第三固定槽13位于所述咬合件2(3)的相同侧面。如此设置，能够使咬合件2(3)的固定更为稳定，可保证咬合件2(3)在径向方向(左右方向)不发生位移。
本实施例中，所述固定槽采用冲压槽的形式，冲压切舌工艺在咬合件2(3)上成型，冲压深度与咬合件2(3)厚度相同。
本实施例中，所述第一固定槽9上设置有突出部15，所述第一凸起11上设置有与所述突出部15配合的固定孔16。通过突出部15和固定孔16的卡和，能够使得咬合件2(3)在于夹子框架1装配后，保持咬合件2(3)在轴向(上下方向)位置不发生位移。优选地，突出部15垂直于第一固定槽9的底面。当然，本领域技术人员应当理解，所述突出部15也可以设置于第一凸起11上，相应地固定孔16设置于所述第一固定槽9上。此外，也可以将突出部或固定孔设置于第二固定槽10上，相应地在第二凸起12上设置固定孔或突出部，或者将突出部或固定孔设置于第三固定槽13上，相应地在第三凸起14上设置固定孔或突出部。作为优选地，也可以在所有固定槽上设置突出部或固定孔，相应地在所有凸起上设置固定孔或突出部。本方案中，通过卡槽式和突出部、孔吻合式的复合固定设计，使吻合夹在使用的过程中，既能保证在激发前和激发过程中咬合件不发生位移，又能保证患者创口在愈合后能够较为方便拆卸取下。
本实施例中，所述突出部15为半球型凸起，具体地，可通过拉深工艺向下冲压成型。
