DEVICE AND METHOD FOR PREPARING A RECESS IN A BONE |
摘要 |
A punching device for preparing a recess in a bone has a punching tool usable for such a punching device. An implant usable with the punching tool is provided and a method for preparing a recess in a bone are disclosed. The punching device comprises an ultrasonic sonotrode and a punching tool which is fixable to the sonotrode at its proximal extremity. At its distal extremity, the punching tool has a thin-walled portion having a non-rotational symmetric cross-section. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. Subsequently, an implant can be held in such recess. Due to its lack of rotational symmetry, the implant may absorb rotational forces around its longitudinal axis. |
