具有刀替换特征结构的超声外科器械
摘要：
本发明公开了一种设备，所述设备包括轴组件和端部执行器。所述轴组件包括第一联接构件和第二联接构件。所述第一联接构件和所述第二联接构件被构造成能够从第一位置朝向彼此挠曲至第二位置。所述第一联接构件和所述第二联接构件在所述第一位置限定枢转轴线。所述端部执行器包括超声刀和夹持臂。所述夹持臂被构造成能够在所述第一联接构件和所述第二联接构件处于所述第二位置时与所述轴组件联接或分离。所述夹持臂被构造成能够在所述第一联接构件和所述第二联接构件处于所述第一位置时围绕所述枢转轴线朝向和远离所述超声刀枢转。
摘要（英）：

An apparatus includes a shaft assembly and an end effector. The shaft assembly includes a first coupling member and a second coupling member. The first coupling member and the second coupling member are configured to flex toward each other from a first position to a second position. The first coupling member and the second coupling member define a pivot axis in the first position. The end effector includes an ultrasonic blade and a clamp arm. The clamp arm is configured to couple or decouple with the shaft assembly when the first coupling member and the second coupling member are in the second position. The clamp arm is configured to pivot toward and away the ultrasonic blade about the pivot axis when the first coupling member and the second coupling member are in the first position.
