Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A laser surgical unit for use in a surgical operation to perform vaporization and incision of a living tissue, said laser surgical unit comprising: a laser generator for generating a laser beam of a predetermined wavelength; an optical guide which has a first end optically coupled to said laser generator and a second end opposite said first end for guiding said laser beam from said first end to said second end; and a contact laser probe which is connected to said second end of the optical guide to emit said laser beam on living tissue and which includes a specific portion comprising a hydroxyl group in an amount between 0.5 and 10 ppm.
Claim 2
Dependent Claim
113 words
A laser surgical unit for use in a surgical operation to perform vaporization and incision of a living tissue, said laser surgical unit comprising: a laser generator for generating a laser beam of a predetermined wavelength; an optical guide which has a first end optically coupled to said laser generator and a second end opposite said first end for guiding said laser beam from said first end to said second end; and a contact laser probe which is connected to said second end of the optical guide to emit said laser beam on living tissue and which includes a specific portion comprising a hydroxyl group in an amount between 0.5 and 10 ppm.
Claim 3
Dependent Claim
45 words
A laser surgical unit as claimed in claim 1, said contact laser probe having a support portion and a tip portion supported by said support portion to emit said laser beam through said tip portion, wherein said specific portion is restricted to said tip portion.
Claim 4
Dependent Claim
23 words
A laser surgical unit as claimed in claim 2, wherein said tip portion is coated with a coating film containing the hydroxyl group.
Claim 5
Dependent Claim
24 words
A laser surgical unit as claimed in claim 1, wherein said specific portion is restricted to a surfacial area of said contact laser probe.
Claim 6
Dependent Claim
21 words
A laser surgical unit as claimed in claim 1, wherein said laser beam has a wavelength between 1.5 through 15 μm.
Claim 7
Dependent Claim
34 words
A laser surgical unit as claimed in claim 1, wherein said laser beam is selected from the group consisting of an Er:YAG laser beam, a Ho:YAG laser beam, and a CO 2 laser beam.
Claim 8
Dependent Claim
90 words
A laser therapeutic method comprising the steps of providing a contact laser probe including a hydroxyl group in an amount of between 0.5 and 10 ppm, bringing the contact laser probe into contact with living tissue, delivering a laser beam from said contact laser probe, and irradiating said living tissue by said laser beam to perform vaporization and incision of said living tissue while said contact laser probe is heated by a portion of said laser beam absorbed in said contact laser probe, to perform hemostasis in said living tissue.
Claim 9
Dependent Claim
90 words
A laser therapeutic method comprising the steps of providing a contact laser probe including a hydroxyl group in an amount of between 0.5 and 10 ppm, bringing the contact laser probe into contact with living tissue, delivering a laser beam from said contact laser probe, and irradiating said living tissue by said laser beam to perform vaporization and incision of said living tissue while said contact laser probe is heated by a portion of said laser beam absorbed in said contact laser probe, to perform hemostasis in said living tissue.
