Problems solved by technology

Since the green laser absorption layer is shallow, the corresponding coagulation layer is also shallow, so the hemostatic effect is not as good as that of the Nd:YAG laser with a near-infrared laser wavelength of 1064nm.

Embodiment Construction

[0022] The main design solutions of the present invention are described by way of some examples. While the specific examples necessarily bring some limitations to the description of the invention, the above summary of the invention together with these illustrations should be able to explain the principles of the invention.

[0023] figure 1 It is a schematic diagram of a Q-switch intracavity frequency-doubling dual-wavelength laser 20 continuously pumped by a semiconductor laser according to the first design of the present invention. The dual-wavelength laser 20 includes a laser head 21 and a laser controller 10 . The laser controller 10 is connected with the laser head 21 through the main cable 11, provides DC driving current for the semiconductor laser pump head 23 and delivers modulated RF radio frequency power to the Q-switch 50 in the laser head. The cooling and temperature control system of the laser is not shown in this figure. The laser head 21 consists of a semicon...

Abstract

The present invention relates to a laser surgery therapeutic apparatus of high power, dual wavelength and continuous pumping for flash evaporating and therapying soft tissue of human body and a method therefor. The dual wavelength laser generates synchronously laser pulse sequence of visible high power second harmonic of thousands of Hertz and near infrared middle-low power fundamental wave. When the laser is used for prostate operation, the prostate operation will be more hemostatic by using near infrared middle-low power 1064 nm Nd: YAG laser, and the body of prostate with hyperplastic symptom can be extremely effectively removed and evaporated by double frequency 532 nm green laser with high power, so that the urethra can be enlarged.

Description

technical field [0001] The present invention relates to the field of treating soft tissue of human body with continuously pumped Q-opened solid-state laser, especially the field of high-power laser prostatectomy. Background technique [0002] Benign prostatic hyperplasia (BPH) causes urinary frequency, painful urination, and urinary retention. Transurethral surgical resection of obstructed prostate tissue has been the "gold standard" in urological treatment of BPH. Although transurethral resection of the prostate (TURP) is a minimally invasive surgical procedure, it is associated with significant complications mainly due to high blood loss. Laser technology offers a viable treatment option for this common blood loss problem. Over the years, urologists and laser practitioners have used different types of lasers to treat BPH in hopes of finding one that works as well as or better than TURP. The effect of laser prostatectomy depends directly on many factors, including laser ...
