Just some excerpts:

“[0045] In some embodiments, second engagement member 234 is a non-uniformly shaped protrusion configured to facilitate interference fit bonding 235 between elongated body 231 and blade 232. In other embodiments the second engagement member 234 is disposed on the the distal end of blade 232 rather than on the proximal end of the elongated body 231, such that the non-uniformly shaped protrusion is still configured to facilitate interference fit bonding 235 between elongated body 231 and blade 232. Additionally, in some embodiments, blade 232 is injection molded about second engagement member 234 to solidify and define interference fit bonding 235 between elongated body 231 and blade 232. The injection molding process allows for blade 232 to be formed from amorphous materials, e.g., metallic amorphous materials or metallic glass amorphous materials, that have higher material strength properties than the titanium or titanium alloys that are used to form elongated body 231. The injection molding process also avoids the added manufacturing cost of machining intricate features onto blade 232.”


“[0012] A method of manufacturing a waveguide of an ultrasonic surgical instrument provided in accordance with aspects of the present disclosure includes forming an elongated body defining a non-uniformly shaped protrusion extending from a distal end of the elongated body and injection molding an amorphous material over the non-uniformly shaped protrusion to form a blade fixedly engaged with and extending distally from the elongated body”
