Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laser treatment apparatus, and more particularly to a laser treatment apparatus capable of performing treatment by irradiation of laser light and treatment by application of ultrasonic waves simultaneously or individually. .

[0002]

2. Description of the Related Art It is already known to irradiate a part of a body (for example, a pain site) with laser light for treatment or to apply ultrasonic waves for treatment. However, these are currently separately configured as a laser treatment device or an ultrasonic treatment device.

[0003]

However, as described above, when the laser treatment device and the ultrasonic treatment device are separately configured, even if the laser treatment and the ultrasonic treatment are attempted to be performed on the same site, Cannot be performed at the same time, and the treatment time is the sum of the two, resulting in the problem that the treatment requires a long time. Further, since the laser treatment device and the ultrasonic treatment device are separately configured, not only the cost is high, but also a large space is required, which is uneconomical. Furthermore, the probe had to be replaced by laser treatment and ultrasonic treatment, and workability was extremely poor.

[0004]

In order to solve the above-mentioned problems, the present invention has (1) an ultrasonic transducer and an optical fiber for emitting a laser beam in the vibration direction of the ultrasonic transducer,
The laser light emitting end face portion of the optical fiber is opened to the free vibration end face of the ultrasonic oscillator, and further, (2) the optical emitting end face portion of the optical fiber has a lens integrally. Alternatively, (3) a lens is provided on the free vibration end face of the ultrasonic transducer so as to face the end face of the optical fiber.

[0005]

[Operation] The laser light irradiation unit and the ultrasonic transducer unit are integrated,
Laser light treatment and ultrasonic treatment can be performed simultaneously or separately with a single probe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view for explaining an embodiment of a laser probe 16 according to the present invention.
A cable in which an optical fiber 2, a lead wire 3 and the like are provided, and an end portion (not shown) of the cable 1 is connected to a laser oscillator. Reference numeral 11 is a piezoelectric vibrator, 12 is a piezoelectric vibrator holding member for stacking the pressure generating vibrators 11, and 1
Reference numeral 3 denotes a vibrator integrally attached to the piezoelectric vibrator 11, reference numeral 14 denotes a cover for housing the piezoelectric vibrators 11 to 13, and the piezoelectric vibrator holding member 12 is fixed to an inner wall of the cover 14. ing. In addition, 15 is a cable 1
The cover 14 is fixed to the cable fixing device.

A switch 16 is attached to the outer peripheral surface of the cover 14, and by operating the switch 16, laser light is emitted from the tip of the optical fiber 2, or
Although the piezoelectric vibrator 11 vibrates ultrasonically in the direction of the arrow, these can be performed simultaneously or individually.

An end (not shown) of the cable 1 is connected to a laser light generator, and the laser light generator is connected to the laser light generator.
There are keys for adjusting the output of laser light, keys for adjusting the voltage applied to the ultrasonic vibrator, etc.By adjusting these, laser light and ultrasonic waves can be supplied simultaneously or separately. Has become. That is, when the switch 16 is pushed after operating the key provided in the laser light generator, the laser light irradiation and the ultrasonic wave application can be performed at the same time or one of them.

Through holes 12a and 13a are provided in the central portions of the piezoelectric vibrator holding member 12 and the vibrator 13,
The light emitting end side of the optical fiber 2 is inserted through these through holes. The optical fiber 2 may be fixed to the ultrasonic vibrator holding member 12, but is free to move relative to the vibrator 13. Therefore,
When the surface 13 ′ of the oscillator 13 is applied to the treated area and the switch 16 is pressed, the laser light from the optical fiber 2 and the vibration of the oscillator 13 can be applied to the treated area simultaneously or separately. .

It is also possible to diffuse the laser light emitted from the tip of the optical fiber 2 by integrally attaching the lens 4 to the tip of the optical fiber 2. It is also possible to integrally attach the lens 17 to the tip of the through hole 13a of the laser. When the lens 17 is attached to the oscillator 13, the intensity of the laser light to be emitted is the vibration of the oscillator. The therapeutic effect can be accelerated depending on the condition.

[0011]

As is apparent from the above description, according to the present invention, irradiation of laser light and application of ultrasonic vibration can be performed simultaneously or separately by using a single probe, so that the treatment time can be increased. Can be shortened and the treatment efficiency can be improved. Moreover, since it is not necessary to replace the probe between the laser light treatment and the ultrasonic treatment, the work efficiency can be remarkably improved.
