Abstract:
A laser light transmitting probe having at least one flat surface, which transmits laser light to living tissue to permit an incision, vaporization, an exfoliation and hemostasis. According to a preferred embodiment, a base portion of the probe is provided with a cylindrical part, a conical part and two flat surfaces formed on the both sides of the conical part. A surface layer, which contains laser light absorbing particles, laser light scattering particles having a larger refractive index than that of the material of the probe and a binder made from a laser light transmissible material, is formed on the flat surface for effective laser light irradiation. Due to the structure of a flat part provided with the flat surfaces, various types of surgical treatments can be performed for various types of treated target are of tissue with only this probe.

Abstract:
Laser light apparatus for medical treatment to permit amputations, incisions, vaporization of living tissues of an animal such as a human body, thermal therapy and the like. This apparatus consists of a laser light generator, a laser light transmissive probe system and a laser light transmitting system. The laser light transmissive probe system is provided with an opposed pair of laser light transmissive probes. The opposed pair of probes can be controlled by a medical operator so as to be moved into or out of contact with each other at their laser light emitting portions. Laser light is transmitted to the opposed pair of probes from the laser light generator through the laser light transmitting system. Then, a target area of living tissues is pinched by the opposed pair of laser light transmissive probes so as to be disposed between the opposed pair of laser light emitting portions.

It includes a laser light emitting means, a coolant supply passage located in the balloon, a coolant discharge passage located in the balloon for discharging the coolant, and a coolant circulating means for supplying the coolant to the balloon through the coolant supply passage to inflate the balloon while discharging the coolant through the coolant discharge passage.
Abstract:
A laser light irradiation apparatus used for medical treatment of tissues. According to a preferred embodiment, the apparatus comprises a probe, an optical fiber feeding laser light into the probe and a lead wire for detecting a temperature being inserted through and projecting from the probe. Then, the probe contains laser light scattering particles for uniform irradiation of the laser light against the tissues. Further, the probe is fabricated from a laser light tramissive synthetic material, and the fore end of a core of the optical fiber and the inserting part of the lead wire are in the synthetic material of the probe for easy molding for this apparatus.
Abstract:
A laser light irradiation apparatus used for medical treatment of living tissues. According to a preferred embodiment, the apparatus comprises a probe and a plural number of optical fibers. The optical fibers surround the axis of the probe. Laser light goes through each optical fiber and is applied to the probe. Then, the laser light is emitted from the probe to uniformly irradiate the tissues, and if desired, against the tissues over a broad area. Further, a guide wire and/or a lead wire for detecting a temperature can be placed so as to be coaxial with the probe. Therefore, a perforation of a normal part of the blood vessel can be prevented.

Abstract:
The present invention provides a medical surgical or dental laser light irradiating apparatus which enables operators as well as third persons to precisely view the treatment. The medical laser light irradiating apparatus of the present invention comprises an optical fiber 3 for emitting from its front end the laser light which is incident upon the rear end thereof from said laser light supply means, a handpiece 1 for holding said optical fiber 3, an light incident face 21 which is made integrally with said handpiece 1 so that it faces at least a laser light irradiated area, imaging means 20 for imaging of at least laser light irradiated area based upon the light which is received through the light incident face 21, display means 30 for displaying a result of imaging from said imaging means 20, and jetting means 40, 40A, 41, 42 for jetting an air to an area in front of said light incident face 21.
Abstract:
The present invention relates to a target material which enables, for example, the blotch to be uniformly and efficiently irradiated with laser light for elimination thereof.In order to modify the living tissue by being irradiated with laser light, the liquid target including laser light absorbing powders having a particle size of not larger than 40 .mu.m, which are dispersed in a dispersing medium is applied on the surface of the living tissue. Then the surface of the tissue on which the target material is applied is irradiated with the laser light. The laser light causes the temperature of the target material to be elevated so that vaporization of the tissue occurs.
