Abstract
A microscope for operation body 1 having an objective lens 4 and eyepieces 5 is combined with a cap that is capable of covering the entire part of the microscope body 1 and which is made of a sterilizable elastic material such as rubber. A retaining portion 7 projecting to retain the cap is provided on the microscope body 1 and a mounting portion engageable with the retaining portion 7 is provided on the cap.
Claims43
A sterile instrument cover for covering an exterior of a surgical microscope having at least a main body portion, a moveable lens mount portion that is moveable relative to the main body portion, and a connecting portion between the moveable lens mount portion and the main body portion, the sterile instrument cover comprising:
- a deformable portion for covering an exterior surface of the connecting portion of the microscope, the deformable portion conforming to movement of the moveable lens mount portion relative to the main body portion;
- and
- a non-deformable portion having upper and lower cap portions connected by the deformable portion for covering exterior surfaces of at least a part of the main body portion and at least a part of the moveable lens mount portion such that the main body portion is substantially contained within and covered by the lower cap portion, the moveable lens mount portion is substantially contained within and covered by the upper cap portion, and the deformable and non-deformable portions cover an entire exterior surface of the microscope.
A method of placing a sterile instrument cover over an exterior of a surgical microscope having at least a main body portion, a moveable lens mount portion, and a connecting portion between the main body portion and the moveable lens mount portion, the method comprising the steps of:
- providing a sterile instrument cover having a deformable portion to conform to movement of the connecting portion of the microscope as the moveable lens mount portion of the microscope moves relative to the main body portion thereof, and a substantially non-deformable portion having upper and lower cap portions connected by the deformable portion to conform to exterior surfaces of both at least a part of the main body portion and at least a part of the moveable lens mount portion of the microscope;
- opening the sterile instrument cover and slipping the sterile instrument cover over the microscope;
- and
- fitting the sterile instrument cover on to the microscope such that an entire exterior surface of the microscope is covered by the deformable and non-deformable portions with the main body portion being substantially contained within and covered by the lower cap portion, and with the moveable lens mount portion being substantially contained within and covered by the upper cap portion.
A sterile instrument cover for covering an exterior of a surgical microscope having at least a main body portion, a moveable lens mount portion that is moveable relative to the main body portion, and a connecting portion between the moveable lens mount portion and the main body portion, the sterile instrument cover comprising:
- a deformable portion for covering an exterior surface of the connection portion while adaptably conforming to movement of the connecting portion of the microscope as the moveable lens mount portion of the microscope moves relative to the main body portion thereof;
- and
- a non-deformable portion having upper and lower cap portions connected by the deformable portion for covering exterior surfaces of at least a part of the main body portion and at least a part of the moveable lens mount portion of the microscope such that the main body portion is substantially contained within and covered by the lower cap portion, the moveable lens mount portion is substantially contained within and covered by the upper cap portion, and the deformable and non-deformable portions cover an entire exterior surface of the microscope, the non-deformable portion formed of a material capable of withstanding a sterilizing process.
A sterile surgical microscope comprising:
- a microscope main body;
- a movable lens mount-portion that is movable relative to said main body;
- a connecting portion defined between said main body and said movable lens mount portion;
- and
- a cover member covering said microscope main body, said movable lens mount portion and said connecting portion, said cover member including:
- a deformable portion for adaptably conforming to an exterior surface of said connecting portion as said movable lens mount portion moves relative to said main body, said deformable portion conforming to follow the movement of said movable lens mount portion at said connecting portion, and
- a non-deformable portion having upper and lower cap portions connected by said deformable portion for conforming to entire exterior surfaces of both at least a part of said main body and at least a part of said movable lens mount portion, said non-deformable portion conforming to the exterior of said main body and the exterior of said movable lens mount portion, wherein the main body portion is substantially contained within and covered by the lower cap portion,
- wherein the moveable lens mount portion is substantially contained within and covered by the upper cap portion, and
- wherein said cover member covers the entire exterior surfaces of said main body, said movable lens mount portion, and said connecting portion.
A sterile surgical microscope comprising:
- a main body;
- a movable portion that is movable relative to said main body;
- a connecting portion defined between said main body and said movable portion;
- and
- a cover member covering said main body, said movable portion and said connecting portion, said cover member including:
- a deformable portion for adaptably conforming to movement of said connecting portion as said movable portion moves relative to said main body, said deformable portion adaptably conforming to follow the movement of said movable portion at said connecting portion, and
- a non-deformable portion including upper and lower cap portions for conforming to entire exterior surfaces of both at least a part of said main body and a part of said movable portion, said non-deformable portion conforming to the exterior of said main body and the exterior of said movable portion, said non-deformable portion being formed of a material capable of withstanding a sterilizing process,
- wherein the main body portion is substantially contained within and covered by the lower cap portion,
- wherein the moveable lens mount portion is substantially contained within and covered by the upper cap portion,
- wherein said cover member covers entire exterior surfaces of said main body, said movable portion, and said connecting portion, and
- wherein said cover member is divided into at least two parts.
A sterile instrument cover for covering an exterior of a surgical microscope having at least a main body portion, a moveable lens mount portion that is moveable relative to the main body portion, and a connecting portion between the moveable lens mount portion and the main body portion, the sterile instrument cover comprising:
- a lower cap portion for fixedly conforming to an exterior surface of at least a part of the main body portion of the microscope such that the main body portion is substantially contained within and covered by the lower cap portion;
- an upper cap portion for fixedly conforming to an exterior surface of at least a part of the moveable lens mount portion such that the moveable lens mount portion is substantially contained within and covered by the upper cap portion;
- and
- a deformable portion for adaptably conforming to an exterior surface of the connecting portion of the microscope as the moveable lens mount portion moves relative to the main body portion, the deformable portion disposed to connect the lower and upper cap portions.
