    摘要： A circular stapler apparatus for stapling tissue has a circular stapling head operable to drive staples toward an anvil to form the staples in a circular array. The anvil includes an anvil head, a proximal shaft extending proximally from the anvil head and having a proximal end disposed in a first plane, and a first pivot connecting the anvil head to the proximal shaft. The first pivot is operable to be disposed in a second plane that is laterally offset from the first plane. The anvil is configured to rotate via movement through multiple pivot points. The anvil may be configured to rotate to a position in which a portion of the anvil head is disposed below the first pivot and between the first pivot and the proximal shaft such that the anvil head is acutely angled with respect to a longitudinal axis of the proximal shaft.

    摘要： Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.
