Surgical device
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 law, 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, and a ball bearing disposed within the channel.
1. A surgical device, comprising:
a first jaw; and
a second jaw coupled to and movable relative to the first jaw, along a pivot axis, between a closed position and an intermediate open position while within a plane, the plane intersecting the first and second jaws, the second jaw being movable relative to the first jaw between the intermediate open position and a fully opened position at least rotationally around the pivot axis, the pivot axis being located within 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.
2. The surgical device according to claim 1 , wherein the second jaw is configured to move relative to the first jaw between the closed and intermediate open positions by translating along a longitudinal axis extending through and parallel with the plane.
3. The surgical device according to claim 1 , further comprising a first drive shaft, wherein rotation of the first drive shaft moves the second jaw relative to the first jaw between the closed position and the intermediate open position.
4. The surgical device according to claim 3 , wherein the first jaw and the second jaw include a camming arrangement configured to move the first and second jaws between the intermediate open and fully opened positions.
5. The surgical device according to claim 4 , 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, wherein the camming arrangement includes a channel disposed along at least one of the arm or the sleeve, and a cam follower disposed within the channel.
6. The surgical device according to claim 3 , further comprising:
a second drive shaft; and
a surgical member disposed within the first jaw and operatively coupled to the second drive shaft such that rotation of the second drive shaft moves the surgical member.
7. The surgical device according to claim 6 , wherein the surgical member includes at least one of a cutting element or a stapling element.
8. The surgical device according to claim 7 , further comprising an electromechanical driver operatively coupled to the second drive shaft to rotate the second drive shaft.
9. The surgical device according to claim 1 , further comprising:
a further drive shaft; and
a surgical member disposed within the first jaw and operatively coupled to the further drive shaft such that rotation of the further drive shaft moves the surgical member.
10. A surgical device, comprising:
a first jaw;
a second jaw coupled to and movable relative to the first jaw between a closed position and an intermediate open position while within a plane, the plane intersecting the first and second jaws, the second jaw being movable relative to the first jaw between the intermediate open position and a fully opened position about a pivot axis, the pivot axis being located within 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; and
a first drive shaft, wherein rotation of the first drive shaft moves the second jaw relative to the first jaw between the closed position and the intermediate open position.
