Surgical instruments with movable member
First Claim
1. A surgical instrument comprising:
- a hollow shaft having an inner passage;
a working piece mounted to the distal end of said shaft;
an ultrasonic transducer to produce vibratory mechanical energy that is applied to said shaft to be deliberately propagated along said shaft to vibrate said working piece, wherein the vibratory mechanical energy along said shaft has a pattern with at least one nodal point of reduced energy;
a movable member pivotally mounted on said shaft at a said nodal point of the vibratory mechanical energy in cooperative relationship to said working piece;
a connecting element extending along the shaft inner passage having one end exiting thorough an opening in said shaft and connected to said movable member; and
an actuating member connected to said connecting element which upon actuation pushes and pulls on said connecting element to move said movable member toward and away from said working piece.

Abstract
A surgical instrument includes a hollow shaft having an inner passage and a working piece at the distal end of the shaft. A movable member is pivotally mounted on the shaft in cooperative relationship to the working piece and a connecting element extends along the shaft inner passage and has one end exiting thorough an opening in said shaft and connected to the movable member. An actuating member is connected to the connecting element which upon actuation pushes and pulls on the connecting element to move the movable member toward and away from the working piece. An ultrasonic transducer can supply mechanical energy to the shaft to vibrate the working piece, the movable member is mounted to the shaft at a nodal point of the energy pattern along the shaft and the opening in the shaft for exit of the connecting element to the movable member is also at a nodal point.
