Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
A hand-held portable laser generating system for use in surgical applications comprising outer casing means having a first half section and a second half section, each of said first half section and said second half section having a plurality of grooves formed in an interior portion thereof which together form a plurality of annular interior grooves in said outer casing means when said first half section and said second half section are joined together, said first and second half portions of said outer casing means further defining a tip portion having a groove therein through which a bundle of optical fibers may pass; means for generating a laser beam disposed within said outer casing means; O-ring means positioned in said grooves for surrounding and supporting said generating means, whereby said generating means may be precisely positioned in said outer casing means; and means for carrying a laser beam produced by said generating means to a surgical tool, said carrying means being disposed in said groove.
Claim 2
Dependent Claim
165 words
A hand-held portable laser generating system for use in surgical applications comprising outer casing means having a first half section and a second half section, each of said first half section and said second half section having a plurality of grooves formed in an interior portion thereof which together form a plurality of annular interior grooves in said outer casing means when said first half section and said second half section are joined together, said first and second half portions of said outer casing means further defining a tip portion having a groove therein through which a bundle of optical fibers may pass; means for generating a laser beam disposed within said outer casing means; O-ring means positioned in said grooves for surrounding and supporting said generating means, whereby said generating means may be precisely positioned in said outer casing means; and means for carrying a laser beam produced by said generating means to a surgical tool, said carrying means being disposed in said groove.
Claim 3
Dependent Claim
35 words
A hand-held portable laser generating system according to claim 1, wherein said tip portion is sealed by means of an optical transmitting window, whereby said outer casing may be sterilized without damaging said generating means.

Dependent Claim
19 words
A hand-held portable laser generating system according to claim 1 wherein said generating means comprises a helium neon tube.
Claim 5
Dependent Claim
25 words
A hand-held portable laser generating system according to claim 1 wherein said generating means is a flash tube excited neodymium, doped yttrium, aluminum garnet crystal.
Claim 6
Dependent Claim
33 words
A hand-held portable laser generating system according to claim 1 wherein said generating means comprises a laser crystal excited via radiation transported from a remotely sited power supply via an optical fiber bundle.
Claim 7
Dependent Claim
25 words
A hand-held portable laser generating system according to claim 1 wherein said generating means comprises the output end of a phased array composite fiber oscillator.
