The present invention relates to a prepuce
cutting device, which solves the technical problem of the defect of the prior prepuce
cutting device which can not expand along with the prepuce erection. The present invention provides an open-loop prepuce
cutting device which comprises a cutting ring and a
bandage; the external circumference of the cutting ring is provided with an annular groove and the
bandage can bind the prepuce in the annular groove; the cutting ring with certain flexibility is provided with a fracture; the
bandage can be a retractable flexible bandage and the flexible bandage can select sterilized and disinfected nylon line, suture, flexible
rubber ring, etc., so the abundant prepuce of the patient is bound on the cutting ring and the partial prepuce naturally falls off due to
avascular necrosis. As the cutting device is the open-
loop design, the internal
diameter can be automatically adjusted, and when the prepuce erects, the ring can expand, and when the
penis weakens, the ring can synchronously shrink, thus greatly reducing the patient pain. The present invention with the advantages of simple structure, convenient use, low cost and less pain is applied in the prepuce cutting operation.
