Claims
- 1. An end effector for an ultrasonic surgical instrument, said end effector comprising:
an ultrasonic blade having a proximal and a distal end; a clamp arm having a proximal and a distal end and configured for movement with respect to the blade; the clamp arm having a clamping surface and positioned for clamping tissue between the clamping surface and the blade; and the clamping surface defining at least one longitudinal axis, the longitudinal axis defining a raised clamping surface.
- 2. The end effector of claim 1, wherein the cross section of the raised clamping surface is a rectangle.
- 3. The end effector of claim 1, wherein the cross section of the raised clamping surface is a triangle.
- 4. The end effector of claim 1, wherein the cross section of the raised clamping surface is rounded.
- 5. The end effector of claim 1, wherein the raised clamping surface has a first dimension at the proximal end of the clamp arm and a second dimension at the distal end of the clamp arm.
- 6. The end effector of claim 1, wherein the cross section of the clamping surface is rounded.
- 7. The end effector of claim 1, wherein the raised clamping surface is non-linear with respect to the at least one longitudinal axis.
- 8. The end effector of claim 7, wherein the cross section of the raised clamping surface is a rectangle.
- 9. The end effector of claim 1, wherein the blade has a rounded cross section.
- 10. An end effector for an ultrasonic surgical instrument, said end effector comprising:
an ultrasonic blade having a proximal and a distal end; a clamp arm having a proximal and a distal end and configured for movement with respect to the blade; the clamp arm having a clamping surface and positioned for clamping tissue between the clamping surface and the blade; and the clamping surface defining two longitudinal axes, and each longitudinal axis defining a raised clamping surface.
- 11. The end effector of claim 10, wherein the cross section of at least one of the raised clamping surfaces is a rectangle.
- 12. The end effector of claim 10, wherein the cross section of at least one of the raised clamping surfaces is a triangle.
- 13. The end effector of claim 10, wherein at least one of the raised clamping surfaces has a first dimension at the proximal end of the clamp arm and a second dimension at the distal end of the clamp arm.
- 14. The end effector of claim 10, wherein the cross section of at least one of the clamping surfaces is rounded.
- 15. The end effector of claim 10, wherein at least one of the raised clamping surfaces is non-linear with respect to a longitudinal axis.
- 16. The end effector of claim 15, wherein the cross section of the raised clamping surface is a rectangle.
- 17. An end effector for an ultrasonic surgical instrument, said end effector comprising:
an ultrasonic blade having a proximal and a distal end; a clamp arm having a proximal and a distal end and configured for movement with respect to the blade; the clamp arm having a clamping surface and positioned for clamping tissue between the clamping surface and the blade; and the clamping surface defining a “U”-shaped channel.
- 18. The end effector of claim 10, wherein the blade has a rounded cross section.
