Abstract

Abstract A laser therapeutic apparatus having an oscillator for generating a laser beam, a condenser lens for condensing the laser beam radiated from the oscillator, a plurality of optical fiber cables for guiding the condensed laser beam, and a probe connected to the distal end of each of the optical fiber cables to apply the laser beam to an affected part of a human body. The probe may be detachably connected to the distal end of the optical fiber through an optical connector. A plurality of optical fibers may have their respective laser beam emergent ends dispersedly disposed over the distal end portion of a probe casing constituting the probe. There may be prepared detachable cap-shaped attachments having various sizes which are conformable with various affected parts of patients, and a selected one of the attachments may be attached to the distal end portion of the probe casing. Thus, it is possible to carry out laser therapy efficiently and effectively.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 109 words
A probe, for connection to a laser beam source to irradiate the skin of a patient, comprising: a plurality of individually encased optical fibers, each of said optical fibers having a laser beam emergent end and each being separately connectable and detachable from a laser beam source; and a spring clip connectable to said laser beam emergent ends for disposal around the digit of a patient to hold said laser beam emergent ends at locations remote from each other so that when the spring clip is disposed on the digit of a patient the laser beam emergent ends are disposed for irradiating various spaced apart areas of the digit.
Claim 2
Dependent Claim 109 words
A probe, for connection to a laser beam source to irradiate the skin of a patient, comprising: a plurality of individually encased optical fibers, each of said optical fibers having a laser beam emergent end and each being separately connectable and detachable from a laser beam source; and a spring clip connectable to said laser beam emergent ends for disposal around the digit of a patient to hold said laser beam emergent ends at locations remote from each other so that when the spring clip is disposed on the digit of a patient the laser beam emergent ends are disposed for irradiating various spaced apart areas of the digit.
Claim 3
Dependent Claim 38 words
A probe according to claim 1, wherein said optical fibers extend through holes in said spring clip, each of said holes having a diameter larger than the diameter of a laser beam that emerges from the optical fibers.
Claim 4
Dependent Claim 31 words
A probe according to claim 1, wherein each of said optical fibers includes a second end opposite said laser beam emergent end and an optical connecting disposed on said second end.
