ABSTRACT:
An objective lens cover assembly for employment in a sterile or nonsterile disposable operating microscope drape. The assembly includes a housing adapted to frictionally engage the objective lens frame of the microscope, and to removably receive a lens cover in positive locking and sealing engagement therewith. The housing includes a circumferential flange for seating the lens cover, and a resilient peripheral portion extending downwardly from said flange for receiving the lens cover. The resilient peripheral portion includes resilient lens cover retaining means including a plurality of inwardly deflectable projections, each having a base face spaced from the circumferential flange to define lens cover retaining slots. When the lens cover is received in the housing, the lens cover deflects the lens cover retaining means outwardly to seat the lens cover in the retaining slots. The lens cover is disengaged from the housing by flexing the lens retaining means outwardly.
