Abstract: According to one embodiment of the invention, a system for removing a cover from a medical instrument includes a flexible cover configured to cover at least a portion of a medical instrument, an insertion element coupled proximate a first end of the flexible cover, a pair of substantially parallel perforations formed in the insertion element, a pair of substantially parallel score lines formed in the cover and aligned with the pair of substantially parallel perforations. A portion of the insertion element between the pair of substantially parallel perforations is removable from the insertion element and a portion of the flexible cover between the pair of substantially parallel score lines is removable from the flexible cover when a force is applied to the portion of the insertion element between the pair of substantially parallel perforations.

Abstract: According to one embodiment of the invention, a microscope drape coupling system includes a first adapter configured to couple to a first objective lens barrel of a first microscope, a housing configured to rotatably couple to the first adapter, and a substantially flat transparent protective lens coupled within the housing such that a geometric normal to the transparent protective lens forms an angle with respect to an optical axis of a first objective lens housed within the first objective lens barrel when the housing is coupled to the first objective lens barrel.
