Laminated ultrasonic end effector
First Claim
1. A laminated ultrasonic end effector having a distal end and a proximal end and comprising at least two stamped pieces of sheet stock which are laminated together and at least one lumen extending from the distal end to the proximal end and wherein first and second stamped pieces of sheet stock are laminated together, and each of the stamped first and second pieces of sheet stock defines half of a cylindrical connector at a proximal end of the laminated ultrasonic end effector which has threads stamped into an interior surface of each half cylindrical connector, such that the first and second half pieces define a cylindrical connector having threads on the interior surface thereof providing a threaded connector connecting to an acoustic transmission assembly.

Abstract
A laminated ultrasonic waveguide and a method of fabrication thereof including stamping at least two pieces of sheet stock to form stamped parts of the laminated ultrasonic waveguide. The stamped parts are then laminated together to form a laminated ultrasonic waveguide for transferring ultrasonic acoustic energy along a longitudinal axis of the laminated ultrasonic waveguide. The laminated ultrasonic waveguide may be part of an ultrasonic surgical instrument having an active tip end-effector, which is placed in contact with tissue of a patient to couple ultrasonic energy transferred along the laminated ultrasonic waveguide to the tissue. The stamped pieces of sheet stock can also be stamped to form one or more channels extending along the length of the laminated ultrasonic waveguide. The laminated ultrasonic waveguide can also define a connector at a proximal end thereof to transfer ultrasonic energy into the laminated ultrasonic waveguide. In different embodiments, the laminated ultrasonic waveguide comprises first and second (and third or more) stamped pieces of sheet stock that are laminated together.
