Abstract

A surgical device includes a first jaw and a second jaw moveable relative to the first jaw between a first position, in which the first and second jaws are aligned within a plane, and a second position, in which the second jaw is in non-parallel correspondence to the plane. The surgical device may include a surgical member, e.g., a cutting and/or stapling element, disposed within the first jaw, and a second driver configured to cause relative movement of the surgical member in a direction parallel to the plane. The first and second jaws may include a camming arrangement that is configured to move the second jaw between the first and second positions. The camming arrangement may include a channel disposed along at least a portion of one or both of the first and second jaws, a ball bearing disposed within the channel.

Claims

1. A method of operating a surgical device, comprising:

moving a second jaw relative to a first jaw between a closed position and an intermediate open position while within a plane;

moving the second jaw relative to the first jaw between the intermediate open position and a fully opened position at least rotationally about an axis located within the plane;

rotating a first drive shaft about a rotation axis, the first drive shaft configured to move the second jaw between the closed, intermediate open, and fully opened positions, wherein the first jaw and the second jaw include a camming arrangement; and

engaging the camming arrangement when the first and second jaws are moved between the intermediate open and fully opened positions.

2. The method according to claim 1, further comprising:

rotating a second drive shaft; and

moving a surgical member disposed within the first jaw in a direction parallel to the plane and in accordance with the rotation of the second drive shaft.

3. The method according to claim 2, wherein the surgical member includes at least one of a cutting element or a stapling element.

4. The method according to claim 2, wherein the second drive shaft is rotated by an electromechanical driver.

5. The method according to claim 1, wherein the first drive shaft is rotated by an electromechanical driver.

6. The method according to claim 1, wherein the second jaw includes an arm and the first jaw includes a sleeve attached thereto, the arm configured to move longitudinally within and relative to the sleeve, the sleeve and the arm including the camming arrangement that is configured to move the second jaw at least between the intermediate open position and the fully open position, wherein the camming arrangement includes a channel disposed along at least one of the arm and the sleeve, a cam follower disposed within the channel.

7. A method of operating a surgical device, comprising:

moving a second jaw relative to a first jaw between a closed position and an intermediate open position while within a plane, the plane intersecting the first and second jaws; and

moving the second jaw relative to the first jaw between the intermediate open position and a fully opened position at least rotationally around an axis, the axis being located within the plane and parallel with the plane, wherein in the fully opened position, at least a distal end of the second jaw is disposed outside of the plane and out of alignment with a distal end of the first jaw.

8. The method according to claim 7, wherein moving the second jaw relative to the first jaw between the closed and intermediate open positions includes moving the second jaw along a longitudinal axis extending through and parallel with the plane.
