用于致动外科器械的方法和装置
摘要：
本发明提供了用于致动外科器械的各种示例性方法和装置。通常，外科装置可包括一个或多个致动轴，所述一个或多个致动轴被构造成能够有利于所述装置的致动。在示例性实施方案中，所述装置可包括四个致动轴，其中两个致动轴用以有利于所述装置的关节运动，一个致动轴用以有利于所述装置的远侧端部处的钳口的打开和闭合，并且一个致动轴用以有利于移动所述装置的切割元件。在示例性实施方案中，所述一个或多个致动轴中的每一者可包括远侧细长构件和近侧细长构件，所述近侧细长构件具有附接到所述远侧细长构件的远侧端部的近侧端部。所述近侧细长构件可为刚性的，并且所述远侧细长构件可为柔性的。
摘要（英）：

Various exemplary methods and devices for actuating surgical instruments are provided. In general, a surgical device can include one or more actuation shafts configured to facilitate actuation of thedevice. In an exemplary embodiment, the device can include four actuation shafts, two actuation shafts to facilitate articulation of the device, one actuation shaft to facilitate opening and closing of jaws at a distal end of the device, and one actuation shaft to facilitate moving a cutting element of the device. In an exemplary embodiment, each of the one or more actuation shafts can include a distal elongate member and a proximal elongate member having a proximal end attached to a distal end of the distal elongate member. The proximal elongate member can be rigid, and the distal elongate member can be flexible.
