Impacting device and method
An impacting device including a head having a longitudinal axis, a lateral surface and a base surface. The impacting device also includes a recess positioned in the head having a first channel and a second channel, the first and second channels being operably connected to each other. The first and second channels are at an angle with respect to each other when viewed in a plane parallel to the longitudinal axis.
1. An impacting device comprising:
an elongated shaft extending along a first longitudinal axis;
an impacting head configured to be removably attached to the shaft and extending along a second longitudinal axis angled relative to the first longitudinal axis and having a lateral surface and a base surface formed to impact a bone implant when said impacting device is attached to the shaft; and
a recess positioned in the head having a first channel and a second channel, the first and second channels being connected to each other, wherein the first and second channels are at an angle with respect to each other when viewed in a plane parallel to the second longitudinal axis and wherein the first and second channels do not intersect the base surface.
2. The impacting device of claim 1 wherein the first channel is an insertion channel and the second channel is a locking chamber for receiving a guide means, the locking chamber having at least one projection for holding the guide means in the locking chamber.
3. The impacting device of claim 2 , wherein the locking chamber is sized and configured so that the head is rotatable on the guide means about the second longitudinal axis.
4. The impacting device of claim 3 , wherein the locking chamber has a first sloping surface and a second sloping surface.
5. The impacting device of claim 4 , wherein the first and second sloping surfaces form a V-shape.
6. The impacting device of claim 1 , wherein the first and second channels intersect the lateral surface but not the base surface.
7. The impacting device of claim 1 , wherein the angle is between about 20° and about 70°.
8. The impacting device of claim 1 , wherein the second longitudinal axis and the first channel create a further angle between about 20° and 70° when viewed in the plane.
9. The impacting device of claim 2 , wherein a first one of the projections is disposed at a first end of the first channel and a second one of the projections is disposed at a second end of the first channel.
10. The impacting device of claim 9 , wherein the first and second ones of the projections bound the second channel towards an exterior of the head.
11. The impacting device of claim 1 , wherein the head is substantially cylindrical.
12. The impacting device of claim 1 , further comprising a handle operably associated with the shaft, wherein the handle has at least one flat side.
13. The impacting device of claim 5 , wherein the V-shape has a highest point substantially near a center of the second channel.
14. The impacting device of claim 1 , wherein the first and second channels do not intersect an upper surface opposite the base surface.
15. The impacting device of claim 1 , wherein the base surface is substantially continuous and includes no openings therein.
16. The impacting device of claim 1 , wherein the lateral surface and the base surface both intersect the second longitudinal axis.
