剪刀式血管密封器
相关申请的交叉引用
本申请要求2019年10月19日提交的美国临时号62/747725的优先权。
背景技术
1.技术领域
本发明涉及电外科血管密封器，更具体地说，涉及一种具有偏置枢轴以改善人体工程学的血管密封器。
2.相关技术描述
电外科血管密封器用于在外科手术过程中阻塞血管和止血。血管密封器的钳口与电外科发生器互连，所述电外科发生器可以选择性地向钳口供应射频(RF)能量，以干燥和密封已被夹持在钳口之间的血管。常规的血管密封器具有可响应于用户激活而铰接的钳口。例如，钳口可定位在连接到公共铰链销的轴的端部上，使得钳口响应于位于轴的另一端的手柄或手指握柄的用户运动而剪切。然而，由于能量的损失和不平衡的力导致无效的夹紧和用户的手疲劳，这种结构布置在机械上效率低下。因此，需要改进血管密封器的铰链，以提供有效的机械夹紧，同时优化用户的人体工程学。对于开放式手术，还需要使钳口尖端的视野最大化。剪刀式装置可能体积庞大，从而在某些方向上缩小了外科医生的视野。
大多数血管密封装置还使用刀片来分割组织，外科医生可通过操纵触发器来手动部署刀片。在夹紧位置部署钳口时，刀片通过刀轨沿两个钳口的中心向下移动。在以与夹持面(密封表面)相同平面上的轴线为轴进行枢转的装置中，刀片穿过枢轴的中心。为了为刀片伸出的插槽提供间隙并提供足够的机械稳定性，枢轴直径较大(6-7毫米)，需要围绕枢轴的较大部分才能容纳它。
发明内容
本发明是一种在提供人体工程学设计的同时具有有效夹紧的血管密封器。电外科装置包括第一轴，所述第一轴沿着纵向轴线从第一端部延伸到第二端部，并且具有与第一端部相关联的钳口。第一轴包括沿其中间部分定位的柄脚，所述柄脚偏离纵向轴线。第二轴从第一端部延伸到第二端部，并具有与第一端部相关联的第二钳口。第二轴枢转地联接至第一轴的柄脚。第二轴包括具有预定长度的狭槽，所述狭槽接受第一轴的枢轴。第二轴包括第一部分，所述第一部分沿着第一轴线从第二端部延伸到狭槽。第二轴包括第二部分，所述第二部分沿着第二轴线延伸狭槽的预定长度。第二轴包括第三部分，所述第三部分沿着第三轴线从狭槽延伸到第一端部。第二轴包括限定狭槽的一对侧壁。枢轴销延伸穿过第二轴的一对侧壁和第一轴的柄脚。止动件沿着第二轴定位。定向第二轴的第一轴线、第二轴线以及第三轴线，使得当第一钳口和第二钳口彼此接触时，第二轴的第一部分与第一轴的止动件接触。电外科控制器安装在第一轴上并支撑止动件。
附图说明
通过结合附图阅读以下详细描述，将更全面地理解和领会本发明，其中：
图1是根据本发明的血管密封器的侧视图；
图2是根据本发明的血管密封器的相对侧视图；以及
图3是根据本发明的用于血管密封器的偏置枢轴的第一透视图；
图4是根据本发明的用于血管密封器的偏置枢轴的第二透视图；以及
图5是根据本发明的血管密封器的轴的侧视图。
具体实施方式
参照附图，其中相同的附图标记始终表示相同的部分，在图1和图2中可以看到根据本发明的血管密封器10。血管密封器10包括一对钳口12和钳口14，每个钳口安装到相应的轴16和轴18的一端。轴16和轴18的相对端形成用户手柄，并且因此可以包括安装到轴16和轴18中的每一个上的指孔20和指孔22，以允许用户容易地抓握。轴16和轴18在其中间部分通过枢轴24可枢转地彼此联接。如本领域技术人员应认识到的那样，通过以剪切运动驱动指孔20和指孔22以选择性地打开和闭合钳口12和钳口14，来操作血管密封器10。可以将电外科控制器24安装到轴18，以向钳口12和钳口14提供射频(RF)能量，并允许用户在钳口12和钳口14围绕要治疗的组织闭合时选择性地给钳口12和钳口14通电以执行电外科操作。
枢轴24包括从轴18的纵向轴线A-A横向延伸的柄脚30。柄脚30包括枢轴销34，所述枢轴销穿过柄脚30并在两个方向上向外延伸以接合轴18。轴16基本上是线性的，使得枢轴34偏离轴16的纵向轴线A-A。轴18沿着第一纵向轴线X-X从指孔20延伸到靠近枢轴24的点。
参考图3和图4，轴16包括穿过其中形成的纵向狭槽38，以限定两个相对的侧壁40和侧壁42。狭槽38的尺寸可接纳柄脚30，使得侧壁40和侧壁42位于柄脚30的两侧。侧壁40和侧壁42包括用于接纳枢转销34的相应的枢转孔42和枢转孔44，从而将联接轴16枢转至轴18。一对衬套46和衬套48可围绕枢轴销34定位在狭槽38中，以接合并支撑轴16和轴18彼此的联接。轴18的侧壁40和侧壁42从枢转孔42和枢转孔44沿着与轴线X-X倾斜的第二纵向轴线Y-Y延伸。在靠近钳口12和钳口14的点处，侧壁40和侧壁42连接在一起以闭合狭槽38，并且沿着与轴线X-X和轴线Y-Y都倾斜的第三轴线Z-Z延伸。如图2所示，轴线X-X、轴线Y-Y以及轴线Z-Z相对于彼此定位，从而钳口12和钳口14将在轴16和轴18已经枢转的点处彼此完全接合，使得轴16刚接触与轴18相关联的止动件48，如图所示位于电外科控制器24的一侧。在图5中可以看到，对于具有特定尺寸(以英寸为单位)的装置，轴线Z-Z相对于轴线Y-Y的优选角度关系如图5所示。更具体地说，对于44.3毫米的总钳口长度，轴线Z-Z和轴线Y-Y之间的角度约为28度，枢轴和钳口中心线之间的偏离为6.5毫米。
本发明的偏置34枢轴减小了装置10的体积，从而在某些方向上增加了外科医生的视野(与居中的枢轴相比)。另外，使枢轴偏离可以允许使用较小直径的销来使轴绕其旋转(例如2毫米)，从而减小了装置的体积并在需要时提供了刀片行进的位置。
