Patent ID: 7326203

Claim:
A device for therapeutically treating bone, comprising: a) a housing having a base portion, a distal face and a first passage opening onto the distal face and forming a longitudinal axis, b) a probe adapted to advance through the first passage along the longitudinal axis, the probe having a functional element thereon, the probe having a distal end portion having a sharp tip shaped to pierce cortical bone, c) an advancement mechanism adapted to advance the probe through the first passage, and d) an anchor rotatably attached to the distal face of the housing and adapted to provide rotation of the housing about the longitudinal axis, wherein the anchor comprises: a plate comprising: i) a proximal face, ii) a distal face, iii) a first throughhole extending from the proximal face to the distal face, wherein at least a portion of the throughhole forms a portion of a substantially spherical recess, and iv) a second different throughhole extending from the proximal face to the substantially spherical recess, wherein the throughholes have separate proximal openings, a bearing comprising: i) a substantially spherical portion disposed in the substantially spherical recess; and a lock screw inserted into the second throughhole of the plate and fixing the orientation of the bearing.
