Abstract
Abstract A surgical device includes a first jaw and a second jaw in opposed correspondence with the first jaw. A first driver is configured to cause relative movement of the first jaw and the second jaw in a plane. The first driver is configured to engage a drive shaft rotatable about a rotation axis arranged in non-parallel, e.g., perpendicular, correspondence to the plane. The device may also include a surgical member, e.g., a cutting and stapling element, disposed within the first jaw. A second driver is configured to cause relative movement of the surgical member in a direction parallel to the plane. The second driver is configured to engage a drive shaft rotatable about a rotation axis arranged in non-parallel correspondence to the plane.
