Attachments of components of ultrasonic blades or waveguides
First Claim
1. A connection union for an ultrasound therapy system comprising:
- a first component and a second component of the ultrasound therapy system are complementary components, which engage each other with a complementary fitting, a compression fitting over the connection union is formed by a deformed female coupling member which is deformed around the complementary fitting of the first and second components by an electromagnetic metal forming operation which compressively deforms the female coupling member over the complementary fitting of the first and second components of the connection union.

Abstract
A connection union and method for securing together first and second components of an ultrasonic waveguide or blade. The first and second components of the ultrasonic waveguide or blade are formed as complementary components which engage each other with a complementary fitting. Then a compressed fit over the connection union is formed by an electromagnetic metal forming operation which compressively deforms a female coupling member over the connection union. The female coupling member can comprise a separate sleeve which is compressed over the connection union by the electromagnetic metal forming operation. Alternatively, the female coupling member can comprise a terminal end of one of the first and second components which includes a longitudinally extending recess which forms an outer circumferentially extending sleeve which is compressed over the connection union by the electromagnetic metal forming operation. In several embodiments, the first and second components are butted together, and each butted end of the first and second components includes at least one circumferentially extending ridge, around which the female coupling member is deformed during the electromagnetic metal forming operation to form an undercut in the female coupling member. In disclosed embodiments, the first component comprises the shaft of an ultrasonic waveguide or blade and the second component comprises a distal tip end of the ultrasonic waveguide such as an end-effector.
