A patient-referenced surgical support frame and method of use are provided. Accordingly, shielding of necessary light can be better avoided compared with a diaphragm for changing the light-shielding area in a rotationally symmetric manner, for example, a diaphragm for narrowing the opening concentrically, making it possible to improve contrast performance while minimizing brightness reduction. The groove penetrates a front edge of the corresponding side surface and slants outward gradually from a front edge to a rear edge. The width of the ridge structure is a ridge width where the distribution of ordinary light of the light waves propagated through the optical waveguide changes and the distribution of extraordinary light of the light waves does not change, the angle of the ridge structure is less than 90\xb0, and the waveguide-type polarizer has a function of transmitting extraordinary light. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation.
