Abstract
A surgical instrument includes an elongated transmission waveguide defining a longitudinal axis. The transmission waveguide has a distal end and a proximal end. The at least one strike surface is formed on the proximal end and is configured to receive vibratory energy.
Claims22
A surgical instrument, comprising:
- an elongated vibrational transmission waveguide defining a longitudinal axis, the waveguide having a distal end and a proximal end;
- and
- at least one strike surface formed on the proximal end, the at least one strike surface being configured to receive vibratory energy in the form of mechanical impacts.
A surgical instrument, comprising:
- an elongated ultrasonic transmission waveguide defining a longitudinal axis, the waveguide having a distal end and a proximal end;
- and
- an ultrasonic slide hammer having a distal end and a proximal end, the ultrasonic slide hammer positioned on the proximal end of the waveguide, the ultrasonic slide hammer comprising a transducer configured to produce vibrations at a predetermined frequency.
An ultrasonic instrument, comprising:
- a housing defining a longitudinal axis, the housing having a distal end and a proximal end;
- a transducer configured to produce vibrations at a predetermined frequency along the longitudinal axis;
- and
- a strike plate assembly positioned at the proximal end of the housing, the strike plate assembly comprising a flange defining a strikeable surface having an area configured to receive a mechanical impact and at least one support member coupled to the strike plate and to the housing.
