The ornamental design for a surgical instrumentshaft with hole pattern, as shown and described.
FIG. 1 is a perspective view of a surgical instrument shaft with hole pattern of my new design;
FIG. 2 is a top plan view thereof; and,
FIG. 3 is a first side view thereof.
The environmental structure depicted in broken lines of even length and in dotted lines forms no part of the claimed design. The surface shading lines also form no part of the claimed design but are intended to depict curvature of the shaft that includes the claimed hole pattern. Portions of the article beyond the broken away symbols form no part of the claimed design.
