Abstract
Abstract A system for microsurgical operation using lasers provides a laser microscope having a housing which carries optical means for viewing an operative field producing an image which is enlarged by the microscope and laser means for selectively concentrating a laser beam on the operative field. Multiple operating room video cameras each generate a video signal and allow simultaneous or selective viewing of the enlarged operative field or a normal operative field so that surgical assistants can view the entire operative procedure while the laser surgeon is operating in either the enlarged or normal field image. One or more video monitors are interfaced with the multiple cameras for selectively displaying either the normal or enlarged image of the operative field.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A system for microsurgical operation using lasers comprising: a. A laser microscope system having a housing which carries optical means for viewing an operative field image which is enlarged by the microscope and laser means for selectively concentrating a laser beam on the operative field; b. multiple operating room video cameras each generating a video signal and allowing simultaneous or selective viewing of the enlarged operative field image or of a normal operative field, or of a gross view of the operating room area so that surgical assistants selected and persons not in the operating room can view the operative procedure while the laser surgeon is operating, in either the enlarged or normal field image; and c. one or more video monitors interfaced with the multiple cameras for selectively displaying either the normal or enlarged images of the operative field in the operating room and in remote locations.
Claim 2
Independent Claim
148 words
A system for microsurgical operation using lasers comprising: a. A laser microscope system having a housing which carries optical means for viewing an operative field image which is enlarged by the microscope and laser means for selectively concentrating a laser beam on the operative field; b. multiple operating room video cameras each generating a video signal and allowing simultaneous or selective viewing of the enlarged operative field image or of a normal operative field, or of a gross view of the operating room area so that surgical assistants selected and persons not in the operating room can view the operative procedure while the laser surgeon is operating, in either the enlarged or normal field image; and c. one or more video monitors interfaced with the multiple cameras for selectively displaying either the normal or enlarged images of the operative field in the operating room and in remote locations.
Claim 3
Dependent Claim
67 words
The laser surgical system of claim 1 further comprising one or more closed circuit television loops communicating with a remote location which includes: a. a video camera recording an image of the remote location; b. a monitor at the remote location which displays at least one of the operating room video camera signals; and c. switch means for terminating the video signal to the remote location monitor.
Claim 4
Dependent Claim
25 words
The laser surgical system of claim 1, wherein the remote location communicates with the operating room via a loop forming an audio and visual link.
Claim 5
Dependent Claim
43 words
The laser surgical system of claim 1, wherein the laser microscope includes a floor mounted adjustable stand positioned under the elevated surface means so that components supporting operation of the laser microscope can be connected thereto from a position above the laser microscope.
Claim 6
Dependent Claim
17 words
The laser surgical system of claim 1 further comprising recorder means for recording each video camera signal.
Claim 7
Dependent Claim
24 words
The laser surgical system of claim 5 further comprising character generator means for adding patient information to one or more of the video signals.
Claim 8
Dependent Claim
44 words
The laser surgical system of claim 1 further comprising elevated surface means suspended above the operative field for carrying one or more components of the laser microscope which activate the laser microscope and are separate components from the microscope optics viewed by the surgeon.
Claim 9
Dependent Claim
137 words
The laser surgical system of claim 7, wherein the elevated surface means comprises: a. a generally vertical pedestal extendable and retractable with respect to the ceiling area of an operating room in which the laser surgical operative procedure is to be performed; b. horizontal surface means radiating from the pedestal for providing an expansive surface upon which separate electrical components can be placed; c. electrical supply means for supplying electrical power to the pedestal; d. electrical terminal means on the surface of the pedestal and connected to the electrical supply means for supplying electrical power connections for the components; e. an internal pedestal space; and f. one or more apertures in the pedestal wall and communicating with the internal pedestal space so that component cables can travel from the expansive work surface to the internal pedestal space.
Claim 10
Dependent Claim
37 words
The laser surgical system of claim 8, wherein the pedestal includes a telescoping arm which can retract the expanded surface to a position generally coplanar the ceiling of an operating room in which the surface is disposed.
Claim 11
Dependent Claim
30 words
The laser surgical system of claim 9, wherein the expanded surface is a generally flat horizontal surface mounted at generally right angles to the lower end portion of the pedestal.
