benign prostate hyperplasia (BPH) ablation treatment, 
novel, Modularized and compact structure,Stable, long life laser system 

Since the wavelength is highly absorbed by water and haemoglobin , so the vaporization and coagulation to the prostate tissue can be realised simultaneously. The high power laser energy is transmited by the special side fiber through the endoscopy in visible , its currently the most advanced minimally invasive treatment method. Compared to the traditional surgery, this procedure is a low- trauma, low-pain, low-risk, comfortable and fast recovery .
