A device for extraction of pins of fixation means for fixation of bone fragments at bone fractures is adapted to pull a pin (7) of the fixation means in a backwards direction relative to a sleeve (6) of the fixation means in order to withdraw a front part (11) of the pin (7) from bone material of one of the bone fragments (3, 4) and into the sleeve (6). The extraction device (1) includes members (12, 13, and 14) which are provided to draw or pull the pin (7) backwards relative to the sleeve (6) without thereby subjecting the pin (7) to torsional forces in relation thereto. |
