Circumcision performed by using special instruments generally means circumcision is completed by simultaneously cutting and anastomosing the inner and outer plates of the foreskin by using a foreskin anastomosis instrument, and the operation mode has the characteristics that: short operation time, less bleeding, no need of needle and thread sewing, neat and beautiful appearance and less postoperative scar. Therefore, the foreskin anastomat has great advantages in the circumcision.

However, the foreskin staplers currently in use suffer from the following problems: firstly, the existing foreskin anastomat (such as a 'business ring') is not used for one-time cutting in an operation, but needs a patient to carry the anastomat after the operation, and the foreskin incision is sleeved by 'pressurizing' for several days, so that the life of the patient after the operation is inconvenient, and the problems of foreskin edema, incision pain and the like are easily caused; secondly, when the foreskin is cut in the operation, the base part of the existing foreskin anastomat can shield part of the penis body and the glans part, so that a doctor cannot adjust the length of the foreskin or the frenulum which needs to be reserved under the direct vision condition and cannot accurately adjust the range of the foreskin excision, and therefore, the problems of insufficient safety and low accuracy of the operation are caused due to the possibility of misoperation of excessive or insufficient foreskin excision.
