1. A medical apparatus, comprising:
- an ultrasonic transducer; and
an ultrasonic energy-activated tool coupled to said ultrasonic transducer for conducting a medical procedure under ultrasonic energy, said tool comprising;
an operating tip on the distal end of the tool; and
a male connector component on the proximal end of said tool for coupling said tool to said ultrasonic transducer, said male connector component comprising;
a shank barrel configured to engage a correspondingly shaped recess defined by a female connector component; and
a stud member having a tip barrel and an interrupted threaded portion, said threads interrupted by a pair of diametrically opposed longitudinal flats, said threaded portion disposed between said shank barrel and said tip barrel, said tip barrel being configured to engage a correspondingly shaped recess defined by the female connector component, said shank barrel and said tip barrel being concentrically positioned about a longitudinal axis of said stud member to concentrically position the male connector component with the female connector component when engaged.

Abstract
Disclosed is a mechanical junction for facilitating the rapid attachment and removal of ultrasonic surgical components for the transfer of ultrasonic energy across the junction from an ultrasonic transducer to an ultrasonically activated tool bit. The junction achieves a high, evenly distributed compressive force to optimize propagation of the ultrasonic energy from the transducer to a tool bit, while maintaining a relatively small outside diameter of the ultrasonic tool. Also disclosed are a plurality of ultrasonic energy activated tool tips for introducing and removing an orthopedic prosthesis.

14. A method of removing adhesive from a bone cavity, said adhesive of the type modified by ultrasonic energy, said method comprising the steps of:
-
positioning an ultrasonic energy-activated tool in contact with adhesive in the bone cavity, said tool comprising a generally arrow-shaped projection having a leverage surface; energizing said tool with ultrasonic energy; embedding said projection of said tool in the adhesive; rotating said tool through an edge of less than 360°
to position said leverage surface of said tool beneath unmodified adhesive;deenergizing said tool with said leverage surface positioned beneath unmodified adhesive; leveraging adhesive surrounding said tool from the cavity in the bone; and retracting said tool from said cavity to remove a portion of said adhesive. - View Dependent Claims (15, 16, 22, 23, 24, 25, 26, 27, 28)

17. A method of removing material from an interior surface of a bone, said material of the type modifiable by ultrasonic energy, said method comprising the steps of:
-
providing an ultrasonic energy-activated tool comprising a leverage surface; modifying a portion of the material with ultrasonic energy to provide a pathway for advancing said leverage surface through modified material; advancing said leverage surface of said tool through said pathway; rotating said tool to interlock said leverage surface beneath unmodified material proximal to said leverage surface; and retracting said tool from said interior surface to remove a portion of the material. - View Dependent Claims (29, 30, 31)
