A force dissipating impactor device comprises a bar member including a hollow shaft, a first end, and a second end. The first end of the impactor device provides an impaction surface and the opposite second end of the impactor device provides an implant engagement surface. The implant engagement surface is contoured to mate with a surface of the implant member. The impaction surface is configured to be struck with a mallet or other tool. A plurality of holes are provided in the shaft and penetrate the surface of the bar member. The plurality of holes provided on the shaft surface of the bar member may be arranged such that a line passing axially along the shaft surface intersects at least one of the plurality of holes. Further, the plurality of holes may be arranged in a staggered matrix around the shaft surface. |
