Background technique

Circumcision is one of the most common operations in urology. In the prior art, circumcision is performed in the following two ways: namely, traditional circumcision performed with conventional instruments and circumcision performed with special instruments In circumcision operation, the main steps of traditional foreskin anastomosis performed with conventional surgical instruments include: sharp cutting of the foreskin, hemostasis, and suture. This type of operation has problems such as time-consuming, time-consuming and labor-intensive operation.

Circumcision surgery performed with special equipment usually refers to the use of circumcision and circumcision instruments to cut and anastomize the inner and outer plates of the prepuce at the same time to complete the circumcision operation. The characteristics of this type of operation include: short operation time and bleeding The amount is small, no stitches are required, and the appearance is neat, beautiful, and the postoperative scar is small. Therefore, the use of the circumcision stapler has great advantages.

However, the currently used circumcision stapler has the following problems: First, the existing circumcision stapler (such as the "shang ring") is not used for one-time cutting during the operation, but requires the patient to carry the stapler after the operation. Pressing the “foreskin” incision for several days will cause inconvenience to the life of the postoperative patient, and easily lead to problems such as foreskin edema and incision pain; secondly, the base part of the existing foreskin stapler will block the foreskin during the operation Live part of the penis body and glans part, so that the doctor cannot adjust the length of the foreskin or frenulum under direct vision, nor can he accurately adjust the scope of the foreskin resection. Therefore, there is the possibility of misoperation of excessive or insufficient foreskin resection. The safety of the operation is insufficient and the accuracy is not high.
