MEDICAL DISRUPTING TOOL AND TOOL SET WITH SUCH MEDICAL DISCONTINUING TOOLS FOR GENERATING BONE PENES SUITABLE FOR TRANSPLANTATION

摘要

The first medical cutting tool 1 according to the invention for producing bone chips suitable for transplantation is provided with a shaft 2 which is provided with a receptacle 4 arranged at the proximal end of the shaft by a drive unit. At the distal end of the shaft, a bone chip formation section 3 is arranged, which forms the core of the medical, cutting tool 1. Due to the specific combination of the features of the embodiment according to the invention with a cutting area 5 with a point angle 6 between 110 ° and 170 °, with 2 to 3 teeth 7, which pass into minor cutting edges 8, with a helix angle 9 between 30 ° and 50 ° and with a Diameter between 2mm and 5mm succeeds according to the invention to significantly increase the vitality of the bone chips obtained in comparison to the common, known bone augers or bone milling machines, which is of key importance for the suitability in the context of a transplantation. The load on the remaining bones is also reduced and, in combination with the increased vitality of the bone chips, a faster and gentler implantation in connection with the bone chips is possible.
