FIG. 2 is a rear, right, and top side perspective view thereof.

FIG. 5 is a right side view thereof.

FIG. 6 is a left side view thereof.

FIG. 7 is a bottom view thereof; and,

The appearance of the surgical gas diffuser between the break lines forms no part of the claimed design.

The surface shading is an artefact of filing in the United States of America and does not necessarily form part of the claimed design. The inventors and applicant contemplate removal of a portion or all of the surface shading.

The references to “left,” “right,” “front,” “rear,” “top,” and “bottom” in the figure descriptions are not meant to require certain in-use orientation; the surgical gas diffuser according to the claimed design may be used in any orientation.
