Abstract
The invention relates to equipment consisting of awl and rasp for preparing the medullary cavity when implanting endoprostheses in long bones. According to the invention, each of the shafts is designed as a hollow body. At the cutting teeth arranged on the outer side of the shaft, there are openings which are directed into the shaft interior. The excavated material collects in the hollow space of the awl or rasp shaft and can be removed from there via apertures at the proximal end and distal end of the shaft by irrigation and/or suction, or is removed together with the instrument after the latter has been used.
