    摘要： An ultrasonic handpiece is used for augmenting a bone screw. The handpieces comprise a housing, an ultrasonic converter shiftingly accommodated in the housing, and a sonotrode connected to one end of the ultrasonic converter. The sonotrode protrudes from the housing into the bone screw. An adjuster wheel is adjustably connected to the housing. A spring is provided the ends of which are supported by the ultrasonic converter and the adjuster wheel, respectively. The ultrasonic converter is preloaded in the direction away from the adjuster wheel by setting the adjuster wheel, thereby the sonotrode is urged with a selected force into the bone screw and the augmentation material is pressed out of the bone screw and into the bone.

    摘要： A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

    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.
