Surgical guide with cut resistant inserts

A resection guide configured to guide a resection tool toward a skull, the resection guide comprising:

• a connection body configured to receive a portion of the skull, the connection body defining a lower surface shaped and configured to conform to the portion of the skull;
• a resection guide body coupled to the connection body so as to project from the connection body along a first direction away from the skull when the connection body receives the portion of the skull, the resection guide body defining an upper surface spaced from the lower surface of the connection body along the first direction, and a pair of opposed walls, the pair of opposed walls defining respective inner surfaces that at least partially define at least one resection guide opening that extends from the upper surface to the lower surface along the first direction, the at least one resection guide opening having a length that extends along a second direction that is perpendicular to the first direction, wherein the length of the opening is greater than a cross-sectional dimension of the connection body, the cross-sectional dimension being parallel to the second direction, wherein the resection guide body is at least partially made from a first material;
• and
• a guide member including a guide member body and a tab that extends out with respect to the guide member body, the guide member configured to be at least partially inserted in the at least one resection guide opening such that at least a portion of the guide member body is aligned with each of the opposed inner surfaces along a third direction that is perpendicular to the first direction and the second direction, and the tab is aligned with the walls along the first direction, the guide member having a guide member opening that extends through the guide member body, the guide member opening elongate along a resection axis, the guide member opening configured to receive at least a portion of the resection tool and guide the resection tool along the resection axis, wherein the guide member is at least partially made of a second material that is harder than the first material.
