Methods and devices for joining transmission components
First Claim
1. An ultrasonic surgical device comprising:
- a transducer assembly adapted to vibrate at an ultrasonic frequency in response to electrical energy;
a mounting device having a first end and a second end, the mounting device having a length which is substantially equal to an integral number of one-half wavelengths of the ultrasonic frequency, the mounting device being adapted to receive the ultrasonic vibration from the transducer assembly and to transmit the ultrasonic vibration from the first end to the second end of the mounting device, the first end of the mounting device being coupled to the transducer assembly near an antinode;
a transmission rod having a first end and a second end, the transmission rod having a length which is substantially equal to an integral multiple of one-half wavelengths of the ultrasonic frequency, the transmission rod being adapted to receive the ultrasonic vibration from the mounting device and to transmit the ultrasonic vibrations from the first end to the second end of the transmission rod, the first end of the transmission rod being coupled to the second end of the mounting device by a non-threaded interface near an antinode; and
an end effector having a first end and a second end, the end effector being adapted to receive the ultrasonic vibrations from the transmission rod and transmit the vibrations from the first end to the second end of the end effector;
the first end of the end effector being coupled to the second end of the transmission rod, and the second end of the end effector being disposed near an antinode.

Abstract
A coupling structure releasably attaches a plurality of transmission members to each other. Non-vibratory structures hold a second end of the first transmission member in contact with a first end of the second member. A method including the steps of providing a first non-vibratory structure carrying the first transmission member, and providing a second non-vibratory structure carrying the second transmission member. The method also includes the steps of attaching the first non-vibratory structure to the second non-vibratory structure to hold a coupling end of the first transmission rod in contact with a coupling end of the second transmission rod without the use of a threaded connection between the first and second components.
