1. A surgical instrument comprising:
a probe tip for probing positions in a space;
a tool interface, separate from the tip; and
an optically trackable target;
wherein the optically trackable target is configured to provide optical information with which to determine the positions;
wherein the tool interface is configured to mate with a surgical tool such that the optical trackable target then provides optical information with which to determine positional information for the surgical tool in the space; and
wherein the tool interface comprises channel surfaces defining a channel having a V-shape, the channel surfaces configured to receive a shaft of the tool for coupling the instrument to the surgical tool.
