Abstract

This invention relates to an apparatus for incrementally advancing functional probes through tissue.

Claims

1. 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.

2. The device of claim 1 wherein anchor has a distal face adapted to attach to skin.

3. The device of claim 1 wherein the anchor has a distal face adapted for bony fixation.

4. The device of claim 1 wherein the anchor has a distal face adapted to attach to an external apparatus.

5. The device of claim 1 wherein the anchor has a distal face comprising an adhesive.

6. The device of claim 1 wherein the plate further comprises an annulus extending proximally from the proximal face, formed around the throughhole.

7. The device of claim 6 wherein the annulus has a laterally extending proximal lip.

8. The device of claim 7 wherein the housing further comprises a recess adapted to receive the lip of the annulus.

9. The device of claim 8 wherein the anchor and recess are adapted so that the housing can be at least partially rotated about the first throughhole.

10. The device of claim 8 wherein the recess has a shape comprising a portion of a sphere.

11. The device of claim 1 wherein the bearing further comprises:

ii) an annulus formed upon the proximal portion of the bearing and further having a proximal end portion and a laterally extending proximal lip, and

iii) a third throughhole extending from the distal portion of the substantially spherical portion to the proximal portion of the annulus, defining a proximal opening and a distal opening.
