The high-power holmium laser has accurate cutting capability, and the principle is that the laser beam with stronger power than high-frequency current and common laser power is emitted, and the hyperplasia glands are completely enucleated from the prostate capsule like orange peeling. The cut-off hyperplastic prostate is crushed into smaller particles, and the particles are sucked out of the body by a planing system. The technique has very little effect on the organism of the patient in operation, and particularly has effectiveness and safety for large-sized prostate, elderly or prostate patients combined with other diseases of the whole body. Meanwhile, for a part of benign prostatic hyperplasia patients with complicated vesical calculus or urethral stricture, two diseases can be puzzled simultaneously by only one hospitalization and anesthesia, so that a 'double-carving at one arrow' is realized.
