Abstract
A universal inner diameter mounting ring contains an annular groove within its inner circumference, the ring being integral with a microscope drape. A microscope adapter housing having a universal outer diameter with a protruding annular ring around its circumference engages the groove on the mounting ring. The adapter engages the inner mounting threads of a microscope body at a first end and the threads of an objective lens housing at a second end.

In a disposable thin polymer microscope drape assembly for maintaining a sterile envelope around an operating room microscope having a mounting ring housing integral with a drape for engagement with an objective lens housing of a microscope, the improvement comprising:
- an inner diameter of the mounting ring housing corresponding to an outside diameter of an adapter ring housing;
- a means for attaching the mounting ring housing to the adapter ring housing;
- a first end of the adapter ring housing having a means for engaging a microscope body;
- a second end of the adapter ring housing having a means for engaging a microscope objective lens housing;
- and
- the mounting ring housing having a depth to enclose a lower end of the microscope objective lens housing and retain a clear plastic lens.
In a disposable microscope drape assembly for maintaining a sterile envelope around an operating room microscope having a mounting ring housing integral with a drape for engagement an objective lens housing of a microscope, the improvement comprising:
- an inner wall diameter of the mounting ring housing corresponding to an outside wall diameter of an adapter ring housing;
- a first end of the adapter ring having threads compatibly engaged to threads within a body of the microscope;
- a second end of the adapter ring housing having threads compatibly engaged to threads in a top end of a microscope objective lens housing, the objective lens housing having a descending annular skirt at a bottom end;
- and
- the mounting ring having a depth sufficient to enclose the microscope objective lens housing skirt and having an annular groove on the inner wall to receive an annular protruding member on the outer wall of the adapter ring housing so that the assembly is locked in place over the microscope but can be disassembled for disposal of the mounting ring and drape.
