A surgical shield includes an at least partially rigid shield member extending in at least two spatial dimensions, at least one flexible sheet member, and a coupling element. The shield member has an aperture traversable by a surgical instrument, while the coupling element is provided on the shield member for releasably connecting the shield member to the instrument. The flexible sheet member is attached to the shield member so as to define, with the shield member, an enclosure having one open side opposing the shield member.
