[0002] Male circumcision is not only of great significance for reducing male penile skin infections and urinary tract infections, but also can reduce the incidence of balanitis in adult men, reduce the incidence of vaginal infections and cervical cancer in their spouses, and even has important significance in preventing sexually transmitted diseases including AIDS and reproductive system tumors. At present, manual circumcision and the method of circumcision staplers are usually used to treat redundant prepuce. Compared with the manual cutting and suturing of manual circumcision, the circumcision stapler has the characteristics of smooth incisions, short operation time, and simple operation.

[0003] Related technologies disclose a circumcision stapler, including a stapler body, on which a pusher plate, a staple cartridge, and an anvil assembly are provided, and a plurality of suture staples for suturing the incision are arranged in the staple cartridge; the suture staple includes a staple base and staple legs arranged at both ends in the length direction of the staple base. The anvil assembly and the staple cartridge cooperate with each other to clamp the target tissue. When the stapler is in the firing state, the pusher plate cooperates with the staple cartridge to drive the suture staples in the staple cartridge into the target tissue to complete the suture.

[0004] However, most of the existing circumcision staplers use metal suture staples. After the operation, the suture staples are easily wrapped by tissues and are not easy to fall off. When the staples fall off after the operation, the patient has to endure pain again, so there is room for improvement. Utility Model Content

[0005] In order to improve the problem that the suture staples are easily wrapped by tissues and are not easy to fall off, the present application provides a foreskin stapler with an auxiliary sheet.

The anvil assembly 14 is arranged on the side of the staple magazine 12 away from the staple cartridge 11, and the anvil assembly 14 cooperates with the staple magazine 12 to clamp the target tissue.

[0038] Referring to Figure 2 and Figure 3 , the auxiliary sheet assembly 2 includes a base ring 21 and an auxiliary ring 22. The base ring 21 is attached to the side wall surface of the staple magazine 12 away from the staple cartridge 11. The auxiliary ring 22 is connected to one end of the base ring 21 close to the axis, and the auxiliary ring 22 is attached to the inner side wall of the circumcision knife 13. The base ring 21 and the auxiliary ring 22 are made of a hemostatic elastic soft material. In this embodiment, the base ring 21 and the auxiliary ring 22 are made of medical rubber material.

[0039] Referring to Figure 2 and Figure 3, when the stapler is in the firing state, the circumcision knife 13 penetrates through one end of the base ring 21 close to the axis and then cuts the target tissue, and the staples penetrate through the base ring 21 and suture the target tissue. At this time, the base ring 21 abuts against the skin, the staple base of the staples abuts against the base ring 21, and the two staple legs of the staples penetrate through the base ring 21 and the skin and are squeezed to be buckled with each other; the base ring 21 separates the skin from the staple base of the staples, reducing the possibility of discomfort caused by the contact between the staples and the skin, and at the same time reducing the possibility of the staple base being wrapped by tissues, which is convenient for staple removal after surgery.

[0040] Refer to Figure 4 , an incision part 213 for the circumcision knife 13 to pass through is arranged at the inner diameter end of the base ring 21 close to the axis.

[0041] Refer to Figure 5 , a plurality of separation grooves 212 are further arranged on the base ring 21. When the foreskin stapler is in the firing state, the circumcision knife 13 penetrates through the base ring 21 at the incision part 213. At this time, in the horizontal direction, the base ring 21 breaks from the separation grooves 212 into a plurality of arc shapes. In this embodiment, the separation groove 212 is a rectangular notch in the horizontal direction, and the length dimension of the separation groove 212 is smaller than the width dimension of the base ring 21.

[0042] Refer to Figure 6 , a plurality of cushion blocks 211 are arranged on the side wall of the base ring 21 close to the staple cartridge 12, and the plurality of cushion blocks 211 are evenly distributed along the circumferential direction of the base ring 21. The width dimension of the cushion block 211 is adapted to the width dimension of the staple hole 121, and the length dimension of the cushion block 211 is slightly smaller than the length dimension of the staple hole 121. Relief grooves 4 are respectively arranged through the staple cartridge 12 at both ends in the length direction of the staple hole 121. When the foreskin stapler is in the initial state, the staple base of the staples is located in the staple hole 121 and abuts against the cushion block 211, and the top legs of the staples are respectively located in the relief grooves 4.

[0043] Refer to Figure 6 and Figure 7 , an embedding part 5 for the staple base of the staples to be embedded is arranged on one side of the cushion block 211 away from the base ring 21. In this embodiment, the embedding part 5 is a notch in a semi-circular shape in the vertical direction.
