Surgical devices with articulating end effectors and methods of using surgical devices with articulating end effectors

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.

主权项

1. A surgical device, comprising:
a proximal handle portion; a first elongate shaft extending distally from the proximal handle portion; a second elongate shaft extending distally from the proximal handle portion and being disposed within a first passageway of the first elongate shaft; a third elongate shaft extending distally from the proximal handle portion and being disposed within a second passageway of the second elongate shaft; a first jaw having a proximal end operatively connected to a distal end of the first elongate shaft; and a second jaw having a proximal end operatively connected to a distal end of the second elongate shaft, the first and second elongate shafts being configured to simultaneously rotate about a longitudinal axis of the third elongate shaft with the third elongate shaft being stationary relative thereto, the rotation of the first and second elongate shafts angularly orienting the first and second jaws relative to the longitudinal axis of the third elongate shaft.
