The invention belongs to the field of medical instruments, and particularly relates to a hard laser cystoscope system, which comprises a hard cystoscope, a cold light source host, a camera shooting host and a monitor. The cold light source host, the camera shooting host and the monitor are connected with the hard cystoscope, and the hard cystoscope is further provided with a laser scalpel operating device used for treatment and a laser scalpel system host used with the laser scalpel operating device. The hard laser cystoscope system organically combines cystoscope technology with laser technology, can be specifically divided into a separating mode and an integral mode. As the laser scalpel technology has ability of generating high energy and realizing highly focusing within a short time, laser with suitable wavelengths is selected according to properties of lesions, and treatment methods include that tumor in a bladder of a patient is incised and irradiated, blood of wounds is stopped and the like are realized. The advanced laser scalpel technology is led into cystoscope surgery, and the advanced laser scalpel technology and the cystoscope surgery are organically designed and combined, so that diagnosis of the cystoscope and a laser treatment effect are combined. By the aid of characteristics that incisions of a laser scalpel are smooth, bleeding is low and infection is not easy, surgery recovery rate and accuracy are effectively improved, recurrence rate is reduced, medical quality and medical safety are improved, and unexpected diagnosis and treatment effects are obtained.
