Patent ID: 8801725

Claim:
An instrument for determining the proper orientation for repairing a defect site on a tissue surface, comprising: a shaft having a first end configured to contact the tissue surface, a second end opposite the first end, and a central bore defined by an outer wall extending between the first and second ends, the outer wall having a plurality of channels defined therein; a plurality of probes operatively coupled to the shaft, each probe being slidably disposed within one of the channels in the outer wall of the shaft and including a first end configured to extend past the first end of the shaft and a second end configured to be contained without the second end of the probe extending beyond the second end of the shaft; a biasing member operatively coupled to each of the probes, the biasing members configured to actively bias the first end of the probe past the first end of the shaft and to allow displacement of the second end of the probe within the channel in which the probe is disposed; and at least one indicator operatively coupled to the plurality of probes, the at least one indicator being configured to display the displacements of the probes relative to the first end so that the displacements of the probes may be compared.
