Urological diode laser systems having a glass-fiber application system

摘要

The invention relates to a system for medicinal treatment, in particular for treating benign prostatic hyperplasia BPH, for use in the event of tumor resection or for use in thoracic surgery. The system comprises a diode laser device for producing a laser beam and to an application system based on optical wave guides that can be endoscopically introduced into a patient. Said system is designed in such a manner that the laser beam, produced by the diode laser device is guided through the application system and is emitted by said application system so that biological tissue can be treated in a selective manner with the emerging laser beam.

主权项

1. A medical treatment system comprising:
a diode laser system for the generation of laser radiation; and an application system based on optical waveguide, which can be inserted endoscopically into the patient; wherein said laser radiation has a wavelength in the spectral range of 800-2000 nm; wherein said medical treatment system is constructed in a way that the laser radiation generated by the diode laser system is transmitted through the application system and emitted by the application system, so that biological tissue can be treated selectively with the emitted laser radiation; wherein said laser system emits light at a first wavelength λ1 and wherein said laser system also emits a light at a second wavelength λ2, which is different from the wavelength λ1; wherein the wavelength λ1 is selected within the spectral region from 800 to 1100 nm and where the wavelength λ2 from the spectral region from 1400 to 1500 nm or from 1900 to 2000 nm; wherein said medical treatment system is configured to operate in a mixed mode where laser radiation is emitted by the application system as a combination of simultaneous continuous emission (cw) and pulsed emission; wherein said medical treatment system is configured to control a parameter of the continuous emission of the laser radiation separately from a parameter of the pulsed emission of the laser radiation.
