Background

The minimally invasive treatment technology has replaced the traditional open surgery and becomes the most important treatment means for urinary calculus. In order to improve the removal rate of the calculi, after the calculi are crushed by laser, some calculi with larger volume which can not be discharged with urine need to be taken out by medical staff. At present, the calculus is usually clamped by using an operating forceps, however, in the minimally invasive surgery process, the operating forceps are inconvenient to operate, the wound is easily expanded by opening and closing the forceps handles, great damage is caused to a patient, in addition, each time one calculus is clamped, the calculus needs to be moved out of the body, when a plurality of calculi are taken out, the operating forceps need to continuously stretch into and extend out through the wound, time and energy are wasted, and other medical personnel need to continuously pull at the wound to keep the expanded state, so that manpower is consumed.
