Claims8
An ultrasonic blade coupler, comprising:
- mounting means at one end of the blade coupler for mounting the blade coupler to an ultrasonic energy source;
- and
- a blade element at an other end of the blade coupler comprising a titanium alloy comprising about 6 weight % aluminum and about 4 weight % vanadium and the remainder titanium and trace elements, said blade element being coated with nickel-chrome, to thereby render it sharpenable.
A method for producing an ultrasonic blade coupler, said method comprising the steps of:
- providing a blade coupler having a blade element comprising a titanium alloy comprising about 6 weight % aluminum and about 4 weight % vanadium and the remainder titanium and trace elements;
- and
- coating said blade element with nickel-chrome to facilitate a formation of a sharpenable cutting edge on the blade element.
