Bone removing device
A bone removing device. The device includes a gearing mechanism and a bone removing device housing containing the gearing mechanism. A first non-oscillating surface is operably connected to the gearing mechanism and a first oscillating rasping surface is operably connected to the gearing mechanism. When the gearing mechanism of the bone removing device is operated, the first oscillating rasping surface is oscillated. The first non-oscillating surface may comprise a rasping surface.
1. A bone removing device comprising:
a gearing mechanism,
a bone removing device housing containing the gearing mechanism,
a first non-oscillating surface operably connected to the gearing mechanism, and
a first oscillating rasping surface operably connected to the gearing mechanism,
wherein, when the gearing mechanism is operated, the first oscillating rasping surface is oscillated within a first plane, and
wherein a distance between the first plane and the first non-oscillating surface is adjustable.
2. The bone removing device of claim 1 , wherein
the distance between the first plane and the first non-oscillating surface is a manually adjustable distance.
3. The bone removing device of claim 2 , further comprising
a manually operated height adjuster for adjusting the manually adjustable distance between the first non-oscillating surface and the first plane.
4. The bone removing device of claim 3 , wherein
the manually operated height adjuster comprises a twistable outer housing comprising geared teeth on a first end,
wherein the geared teeth are configured to operate a rack and pinion mechanism so as to increase the distance between the non-oscillating surface and the first plane.
5. The bone removing device of claim 1 ,
wherein a proximal end of the bone removing device housing is adapted to receive a surgical instrument.
6. The bone removing device of claim 5 ,
wherein the surgical instrument comprises a rotating surgical instrument.
7. The bone removing device of claim 6 ,
wherein the rotating surgical instrument is configured to rotate a main drive shaft contained within the bone removing device housing.
8. The bone removing device of claim 7 ,
wherein the main drive shaft is connected to a planetary drive system.
9. The bone removing device of claim 8 ,
further comprising a sun gear and a main planetary gear,
wherein the planetary drive system is configured to provide a ratio between the sun gear and the main planetary gear in order to increase revolutions per minute created by the rotating surgical instrument.
10. The bone removing device of claim 9 , further comprising
an intermediate housing containing a vertical beveled gear and a horizontal beveled gear,
wherein the vertical beveled gear and the horizontal beveled gear are configured to translate a rotational motion into an oscillating linear motion of the first oscillating rasping surface.
11. The bone removing device of claim 10 ,
wherein the horizontal beveled gear comprises a protruding peg that engages an oscillating drive shaft.
12. The bone removing device of claim 11 ,
wherein the first oscillating rasping surface is removably seated within a cavity defined by a main chassis.
13. The bone removing device of claim 1 ,
wherein the first non-oscillating surface comprises an adjustable non-oscillating surface.
14. The bone removing device of claim 13 , further comprising:
a height adjustment knob comprising a geared face.
15. The bone removing device of claim 14 , further comprising:
a spur gear,
wherein the geared face of the height adjustment knob engages the spur gear
and rotation of the height adjustment knob adjusts a distance between
the first non-oscillating surface and
the first oscillating rasping surface.
16. The bone removing device of claim 15 , further comprising:
a worm gear drive connected to the spur gear.
17. The bone removing device of claim 1 ,
wherein the first oscillating rasping surface comprises a plurality of teeth.
18. The bone removing device of claim 1 , wherein the bone removing device comprises
a second non-oscillating surface operably connected to the gearing mechanism, and
a second oscillating rasping surface operably connected to the gearing mechanism,
wherein, when the gearing mechanism is operated, the first and the second oscillating rasping surfaces are oscillated.
19. The bone removing device of claim 1 ,
wherein the first non-oscillating surface comprises a rasping surface.
20. The bone removing device of claim 10 ,
wherein the oscillating drive shaft is detachably connected to the first oscillating rasping surface.
