Abstract

A surgical device. The surgical device may comprise a transducer configured to provide vibrations along a longitudinal axis and an end effector coupled to the transducer and extending from the transducer along the longitudinal axis. The surgical device also may comprise a lower jaw extending parallel to the end effector. The lower jaw may comprise a clamp face extending toward the longitudinal axis. Also, the lower jaw may be slidable relative to the end effector to bring the clamp face toward a distal end of the end effector.

Claims

1. A surgical device comprising:

a transducer configured to provide vibrations along a longitudinal axis;

a blade coupled to the transducer and extending from the transducer along the longitudinal axis, wherein the blade defines a central lumen therein, and wherein the blade further comprises at least one member extended across at least a portion of the central lumen and fixedly secured to the blade at about a distal end of the blade; and

a lower jaw extending parallel to the blade, the lower jaw comprising a clamp face extending toward the longitudinal axis, wherein the lower jaw is slidable relative to the blade to bring the clamp face toward the distal end of the blade.

2. The device of claim 1, further comprising a polymeric clamp pad positioned between the clamp face and the blade.

3. The device of claim 1, further comprising a sheath positioned around at least a portion of the blade.

4. The device of claim 1, wherein the blade comprises a waveguide.

5. The device of claim 1, wherein the at least one member comprises two members and wherein the two members intersect one another at a right angle.

6. The device of claim 1, wherein the at least one member comprises a wire.

7. The device of claim 1, wherein the at least one member extends proximally through the central lumen.

8. The device of claim 7, wherein the at least one member extends proximally through the central lumen in a direction that is not parallel to the longitudinal axis.

9. The device of claim 7, wherein the at least one member comprises a first section and a second section, wherein the first section is positioned at a first angle relative to the longitudinal axis, and wherein the second section is positioned at a second angle relative to the longitudinal axis.

10. The device of claim 9, wherein the first angle is larger than the second angle.

11. The device of claim 1, wherein the clamp face comprises a plug feature extending toward the distal end of the blade, wherein the plug feature is at least partially received into the central lumen when the clamp face is brought toward the distal end of the blade.

12. The device of claim 11, wherein the plug feature has a cross-sectional area smaller than a cross-sectional area of the lumen.

13. The device of claim 1, wherein the blade comprises a distal portion and a proximal portion, and wherein the distal portion and the proximal portion are coupled.

14. The device of claim 13, wherein the distal portion and the proximal portion are coupled by at least one method selected from the group consisting of press fitting, welding, brazing, adhesive bonding, and threading.

15. The device of claim 1, wherein the lower jaw defines a lumen having an opening at a distal portion of the lower jaw.

16. The device of claim 15, wherein the blade defines a cavity configured to at least partially cover the opening when the clamp face is brought toward the distal end of the blade.

17. The device of claim 15, wherein the opening is positioned within a well, defined by the lower jaw, and wherein the blade is configured to at least partially cover the well when the clamp face is brought toward the distal end of the blade.

18. The device of claim 1, wherein the blade is stationary while the lower jaw slides proximally relative to the blade.

19. The device of claim 1, wherein the lower jaw is stationary while the blade slides distally relative to the lower jaw.

20. The device of claim 19, further comprising a frame member coupled to the blade, wherein the frame member defines a slot, wherein the blade comprises at least one pin configured to be received by the slot, and wherein the slot is oriented to exert a torque on the blade as the blade slides distally.

21. A method for processing a surgical device for surgery, comprising:

obtaining the surgical device of claim 1;

detaching the lower jaw extending parallel to the blade; and

performing one of the following actions;

reforming the clamp face of the lower jaw, resterilizing the lower jaw extending parallel to the blade, reattaching the resterilized lower jaw extending parallel to the blade;

or attaching another sterilized lower jaw extending parallel to the blade.
