  • Patent number: 10265084
    Abstract: Perforator for drilling bone tissue, comprising a drive shaft (12) with rotation axis (t), a drill head (14) with the same rotation axis (t), a chipping head (16) arranged coaxially around the later. A first connecting profile (20) is provided on a proximal end (18) of the drill head (14), and a second connecting profile (24) is provided on a distal end (22) of the drive shaft (12) for cooperating with the first connecting profile (20) in order to transfer rotational movement of the drive shaft (12) to the drill head (14), and the drill head (14) and the chipping head (16) being connected to each other displaceably along the rotation axis (t).

  • Publication number: 20170027594
    Abstract: The invention relates to a perforator (10) for drilling bone tissue, comprising: —a drive shaft (12) with rotation axis (t), —a drill head (14) with the same rotation axis (t), —a chipping head (16) arranged coaxially around the drill head (14) characterised by that a first connecting profile (20) is provided on a proximal end (18) of the drill head (14), and a second connecting profile (24) is provided on a distal end (22) of the drive shaft (12) and the drill head (14) is arranged so as to be displaceable with respect to the chipping head (16) along the rotation axis (t) between a proximal position and a distal position, and in the proximal position the second connecting profile (24) on the distal end (22) of the drive shaft (12) cooperates with the first connecting profile (20) such as to transmit rotational motion from the drive shaft (12) to the drill head (14), and in the distal position the first connecting profile (20) on the proximal end (18) of the drill head (14) and the second connecting profile (
