如图1至图10所示，本发明揭示了一种剪刀式电流集成手术器械，包括枢轴连接形成剪式结构的第一轴构件和第二轴构件，所述第一轴构件和第二轴构件自二者的枢轴连接点向前延伸形成可开合的钳口、向后延伸形成中空的第一壳体1和第二壳体2，所述第一壳体1内设置有刀片3和控制所述刀片3在所述钳口内伸缩移动的控制机构，所述控制机构包括驱动刀片3移动的驱动机构和控制所述驱动机构开启的触发机构，所述驱动机构包括依次连接的摇臂6、旋臂4和进刀手柄5，所述摇臂6与所述刀片3相连接，所述进刀手柄5位于所述第一壳体1外并驱动所述旋臂4以二者的连接处为旋转中心同步旋转，所述旋臂4的旋转带动所述摇臂6驱动所述刀片3同步移动；所述触发机构包括弹簧支架7和限位拨叉8，所述限位拨叉8与所述第一壳体1内的圆轴销101枢转连接，且其外端外凸于所述第一壳体1的内侧壁，其内端与所述弹簧支架7卡接，所述限位拨叉8通过旋转驱动所述弹簧支架7做直线运动，进而使得所述弹簧支架7与所述旋臂4相卡接或相分离。初始状态下，所述钳口张开，所述第一壳体1和第二壳体2相分离，所述钳口张开，所述弹簧支架7的端部与所述旋臂4卡接并限制所述旋臂4的旋转，所述刀片5内缩于所述第一壳体1；第二状态下，所述钳口闭合，所述第一壳体1和第二壳体2的内侧壁靠近且不相贴合；第三状态下，所述钳口闭合，所述第一壳体1和第二壳体2的内侧壁在手持压力的作用下贴合，此时，所述限位拨叉8的外端与所述第二壳体2的内侧壁抵接，并旋转驱动所述弹簧支架7与所述旋臂4分离，所述进刀手柄5可驱动所述旋臂4旋转，使所述刀片5在所述钳口内伸缩移动。
具体的如图2-5、7所示，所述第一壳体1内设置有支架102，所述支架102优选为金属制成，所述旋臂4的第一端401的轴心插设有旋转轴11，所述旋转轴11的表面对称设置有一字槽1101，所述旋转轴11穿设于所述金属支架102上，且所述旋转轴11的一端或两端连接有所述进刀手柄5。所述一字槽1101的设置使得所述旋转轴11的表面为非圆形，从而保证所述旋转轴11与所述第一端401、进刀手柄5的连接处不会产生相对转动，确保所述进刀手柄5的旋转可带动所述旋臂4同步旋转。在优选实施例中，所述旋转轴11的两端都设置有所述进刀手柄5，使得使用者从所述第一壳体1的两侧均可以操作所述进刀手柄5，来同时满足左、右手的使用习惯。
为了进一步便于操作，所述进刀手柄5的端部形成直径较大的接触凸点501，来增大所述进刀手柄5的接触面积，提高使用者拨动所述进刀手柄5的稳定性，减少打滑。所述第二壳体2上设置有与所述进刀手柄5的运动轨迹相匹配的避位凹部201，进一步提高所述进刀手柄5的移动流畅性和稳定性。所述第二壳体2与所述限位拨叉8相抵接的部位还设置有开口，使得所述限位拨叉8的顶部可以部分插设于所述第二壳体2内，并与所述第二壳体2 内的第二金属支架202抵接，来提高所述限位拨叉8与所述第二壳体2之间抵接的稳定性。所述限位拨叉8的顶部形成有弧形面，来尽可能减少其与所述第二壳体2之间硬接触后造成的磨损，并有利于所述限位拨叉8的旋转。
如图5、7所示，本方案中的所述第一端401的外表面为圆弧面4011，且所述圆弧面4011与所述旋臂4的杆身连接处形成有限位卡口403，所述弹簧支架7的端部设置有与所述限位卡口403相匹配的凸块701，所述弹簧支架7的移动驱动所述凸块701与所述限位卡口403相卡接或相分离。所述凸块701优选为圆柱体结构，所述圆弧面4011的设置使得当所述弹簧支架7复位回缩时，即使所述旋臂4没有复位，所述凸块701会与所述圆弧面4011抵接，并不会阻碍所述第一端401的旋转，所述第一端401旋转复位时，所述凸块701会沿所述圆弧面4011滑动直至与所述限位卡口403卡接。在其他可行的实施例中，所述第一端401和所述弹簧支架7的端部之间也可以采用其他可行的卡接结构，例如所述弹簧支架7的端部形成卡口，所述第一端401的外边缘形成凸块。
进一步的，所述旋臂4的第二端402处设置有一凸杆4021，所述凸杆4021穿设于所述摇臂6的端部连接孔601内，所述凸杆4021绕所述旋转轴11做圆弧运动，所述金属支架102上设置有一与所述凸杆4021的运动轨迹相匹配的限位滑槽10，所述凸杆4021滑动卡设于所述限位滑槽10内。所述限位滑槽10的设置可以限定所述旋臂4的第二端402的移动范围，从而限定所述刀片3的移动范围和移动长度，并且所述限位滑槽10的设置可以有效保证所述凸杆4021的移动稳定性和流畅性，尽可能地减少晃动，避免所述刀片3移动的卡顿。
所述驱动机构还包括一复位拉簧12，所述复位拉簧12的一端套设于所述摇臂6的端部的卡槽602上，另一端设置于所述第一壳体1的内壁上，所述复位拉簧12的弹力驱动所述摇臂6、旋臂4回复至初始状态。所述复位拉簧12的设置使得当所述进刀手柄5不受外力驱动转动时，所述复位拉簧12的弹力拉动所述旋臂4自动回复至初始状态，相比于仅有所述进刀手柄5控制的手动模式，所述复位拉簧12的设置可以进一步简化操作，避免所述刀片3伸出后忘记缩回就打开所述钳口的情况，提高使用安全性。另一方面，所述复位拉簧12的弹力可以抵消一部分所述旋臂4旋转产生的驱动力，起到减速作用，提高所述进刀手柄5的控制感，避免用力过大造成所述进刀手柄5与第一壳体1之间不必要的损坏。
如图4-6所示，所述弹簧支架7包括相套接的支杆702和复位弹簧703，所述凸块701设置于所述支杆702的前端，所述支杆702上设置有与所述限位拨叉8的内端卡接的圆凸柱704，所述限位拨叉8驱动所述支杆702远离所述第一端401，所述复位弹簧703驱动 所述支杆702复位。优选实施例中的所述第一壳体1的内侧壁为平直表面，所述支杆702与所述第一壳体1的内侧壁平行设置，所述支杆702的移动方向与其延伸方向一致，来尽可能地缩小所述第一壳体1的径向宽度，优化各部件之间的排布，节约所述第一壳体1的内部空间。当然，在其他可行实施例中，所述支杆702也可以不与所述第一壳体1的内侧壁平行。
所述金属支架102上设置有一字型的支杆滑槽1021，所述支杆702的背面具有滑块7021，所述滑块7021滑动嵌设于所述支杆滑槽1021内。所述支杆滑槽1021的延伸方向与所述弹簧支架7的移动方向一致，来使得所述支杆滑槽1021对所述弹簧支架7的移动起到限位作用，并对所述弹簧支架7提高侧向支撑力，保证所述弹簧支架7的直线移动，避免其发生侧向移动，来提高所述弹簧支架7直线移动的稳定性和流畅性。
进一步的，所述触发机构还包括一弹片9，所述弹片9设置于所述第一壳体1内，所述限位拨叉8的侧部具有一可拨动所述弹片9的凸部801，当所述弹簧支架7与所述旋臂4分离时，所述凸部801自所述弹片9的内侧移动至其外侧，以拨动所述弹片9发出提示音。所述弹片9优选为金属片，使其不易折断，并与所述凸部801之间产生较为清脆的提示音。所述弹片9与所述凸部801之间产生的提示音可以及时告知使用者钳口已经将电极片18之间的组织夹紧，可以按压按钮24开始进行电切，同时所述弹簧支架7已与所述旋臂4分离，即所述驱动机构已经解锁，所述进刀手柄5可以控制所述旋臂4进行旋转来驱动刀片3进行移动切割，便捷实际操作，从而避免使用者在所述触发机构锁止所述驱动机构的情况下旋转所述进刀手柄5造成损坏。
如图8-9所示，本方案中的所述第一轴构件还包括与所述第一壳体1连接的第一连接部13和第一钳臂14，所述第二轴构件还包括与所述第二壳体2相连的第二连接部15和第二钳臂16，所述第一连接部13上设置有两个连接圆柱1301，所述第二连接部15上可转动地设置有一焊接圆片1501，所述焊接圆片1501与所述连接圆柱1301焊接，使得所述第一连接部13与第二连接部15枢轴连接，所述第一钳臂14和所述第二钳臂16构成所述钳口。所述第一连接部13、第二连接部15优选使用金属制成。
所述第一钳臂14和所述第二钳臂16在优选实施例中为对称设置并向一侧弯曲延伸，在其他可行的实施例中，所述第一钳臂14和所述第二钳臂16也可以具有其他形状。
具体的，所述第一钳臂14和第二钳臂16均具有绝缘外壳17，所述绝缘外壳17优选为包塑制成。所述第一连接部13、第二连接部15的前端分别插设于所述绝缘外壳17内，所述第一钳臂14和第二钳臂16相对的内表面均设置有通过导线20与开关21电线连接的电 极片18，所述电极片18为所述钳口夹持住组织后与对组织进行凝结的接触面，每个所述电极片18上至少设置有一绝缘片，所述绝缘片可以是本领域技术人员所熟知的任何形状，所述绝缘片的材料不限制，可由任何可绝缘的材料制成，在优选实施例中，所述绝缘片优选为绝缘凸点19，绝缘凸点19优选为陶瓷制成。所述绝缘凸点19的设置使得当钳口内不夹持组织时，两个所述电极片18之间不会紧贴合，来保证两个电极片18之间的绝缘，本方案中分别在所述电极片18的前端或中间设置，在其他可行的实施例中，所述电极片18上也可以设置多个所述绝缘凸点19。每个所述电极片18与所述第一连接部13、第二连接部15的前端之间设置有一绝缘隔层(图中未示出)，来隔开所述电极片18和所述第一连接部13、第二连接部15。
为了使得所述刀片3在所述第一钳臂14、第二钳臂16之间进行伸缩运动，每个所述电极片18的轴线处均设置有一可使所述刀片3通过的刀片滑槽1801。所述刀片滑槽1801向所述金属支架102靠近所述第一壳体1的内侧壁处延伸设置，来容置所述刀片3并使所述刀片3具有足够的滑动距离。
如1、2、3、10所示，所述第一壳体1、第二壳体2的尾端外侧壁上分别设置有用于手持的指圈25，所述指圈25的外壁包覆有护圈软胶，来提高所述指圈25的使用舒适度。
两个所述指圈25之间的所述第二壳体2内设置有电路板23，所述电路板23上设置有所述开关21，所述开关21上设置有弹性按钮24，所述弹性按钮24外凸于所述第二壳体2的内侧壁与所述第一壳体1的内侧壁相对。所述弹性按钮24的弹性来自于其与所述开关21之间设置有弹簧2401，所述弹簧的设置使得所述弹性按钮24按压后进行复位。所述弹性按钮24外凸所述第二壳体2的结构设置使得在第二状态下，所述第一壳体1的内壁与所述弹性按钮24的外表面抵接来触发所述开关21，使得所述电极片18可以通电使用。
本方案中的所述第一壳体1、第二壳体2的内表面优选为平直表面，当钳口从张开到闭合过程中，限位拨叉8不和第二壳体2的平直表面接触，限位拨叉8不发生位移，弹簧支架7的凸块701与限位卡口403不脱离，即旋臂4不解锁。当钳口完全闭合后，第二壳体2和第二金属支架202发生弹性形变后开始和限位拨叉8接触，限位拨叉8开始发生位移，弹簧支架在限位拨叉8的作用下和旋臂4的限位卡扣403解锁。同时该弹性形变触发所述弹性按钮24，这样的结构设置进一步简化了操作步骤，进一步便于在手持状态下快速开启使用，进行夹持和切割。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书 作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
