Abstract
Abstract A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity, wherein the eyepiece and the lens means are configured to facilitate stereoscopic viewing. In a variation of the surgical microscope, a plurality of binocular eyepieces are attached to the microscope body to allow multiple persons to contemporaneously view the magnified object image.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
118 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity, wherein the coupling means comprises a sleeve having an interior in which the supplementary lens is positioned, the sleeve having an aperture in a side thereof in communication with the interior to facilitate interchanging the supplementary lens with other lenses without decoupling the sleeve from the lens means.
Claim 2
Dependent Claim
118 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity, wherein the coupling means comprises a sleeve having an interior in which the supplementary lens is positioned, the sleeve having an aperture in a side thereof in communication with the interior to facilitate interchanging the supplementary lens with other lenses without decoupling the sleeve from the lens means.
Claim 3
Dependent Claim
87 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity and allowing the supplementary lens to be interchanged with an alternate lens without moving the microscope body.
Claim 4
Dependent Claim
87 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity and allowing the supplementary lens to be interchanged with an alternate lens without moving the microscope body.
Claim 5
Dependent Claim
105 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means comprising a cannula having a passage in which the supplementary lens may be removably positioned, the cannula having a distal end configured for introduction into the body cavity through a percutaneous penetration, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity.
Claim 6
Dependent Claim
105 words
A surgical microscope comprising a microscope body, lens means attached to the microscope body for magnifying an object image, an eyepiece attached to the microscope body for viewing the magnified object image, and coupling means attached to the microscope body for retaining a supplementary lens in optical alignment with the lens means, the coupling means comprising a cannula having a passage in which the supplementary lens may be removably positioned, the cannula having a distal end configured for introduction into the body cavity through a percutaneous penetration, the coupling means being configured for introducing the supplementary lens through a percutaneous penetration into a body cavity.
Claim 7
Dependent Claim
18 words
The surgical microscope of claim 3 wherein the coupling means further comprises a sleeve disposed within the cannula.
Claim 8
Dependent Claim
21 words
