[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] like Figures 1 to 5 A stepped locking disposable circumcision stapler is provided, including a sleeved outer ring 11 and an inner ring 12. The outer ring 11 includes a first half ring 1 and a second half ring 2. The first half ring 1 and the second half ring 2 are arranged opposite to each other and can be closed to form a ring structure. The outer side of the first semi-ring 1 is provided with a first limiting block 3, and the outer side of the second semi-ring 2 is provided with a second limiting block 4; The first limiting block 3 and the second limiting block 4 are respectively provided with locking teeth 7 on their opposite sides. The cross-section of the locking teeth 7 is serrated, which is used to enhance the locking stability between the two.

[0021] In addition, the first limiting block 3 is provided with stepped slots 6 distributed along its length direction, and the stepped slots 6 are arranged in a stepped shape. The bottom of the second limiting block 4 is fixedly provided with a locking block 5, which is suitable for embedding into the stepped slot 6 and engaging with the stepped slot 6.

[0022] In addition, the locking teeth 7 are disposed on the adjacent sides of the first limiting block 3 and the second limiting block 4, and the locking teeth 7 of the two are engaged with each other.

[0023] The inner walls of the first semi-ring 1 and the second semi-ring 2 are respectively provided with a ring cutting blade 8. The cross-section of the ring cutting blade 8 is arc-shaped and is integrally set with the inner wall of the semi-ring.

[0024] In addition, the first half-ring 1 and the second half-ring 2 are respectively provided with connecting sleeves 9 at the ends away from the limiting block, and the two connecting sleeves 9 are rotatably connected by the limiting shaft 10.

[0025] The first half-ring 1 and the second half-ring 2 are integrally molded structures, made of medical-grade plastic, steel, or other materials. The material can be selected as needed. The integral molding of the first half-ring 1 and the second half-ring 2 is to improve overall strength and avoid excessive joints that could affect the product's strength performance.

[0026] In addition, the stepped slot 6 has inclined edge structures on both sides, and the shape of the locking block 5 matches that of the stepped slot 6. This design is to reliably lock the locking block 5 into the stepped slot 6 and prevent slippage.

[0027] In addition, the card block 5 and the second limiting block 4 are integrally formed structures, and the front end is provided with a guide slope to facilitate insertion into the stepped card slot 6.

[0028] Specifically: The stepped locking disposable circumcision stapler includes a first half-ring 1 and a second half-ring 2, which are rotatably connected by a limiting shaft 10 to achieve opening and closing action. A first limiting block 3 is fixedly installed on the outer side of the first half-ring 1, and a second limiting block 4 is fixedly installed on the outer side of the second half-ring 2.

[0029] The first limiting block 3 has three stepped slots 6 arranged in a stepped pattern, with the depth of each slot gradually increasing to improve the reliability of locking. The bottom of the second limiting block 4 extends into an integrally formed locking block 5, with a guide slope at its front end to facilitate engagement into the stepped slots 6.

[0030] Furthermore, the first limiting block 3 and the second limiting block 4 are respectively provided with serrated locking teeth 7 on their opposite sides. When the two are closed, the locking teeth 7 engage with each other, enhancing the locking stability and preventing loosening during the operation. In addition, multiple locking positions are provided by setting several locking teeth. The surgeon can select the appropriate position for locking according to the actual situation of the patient's foreskin, realizing adjustable and precise control of the locking force.

[0031] The inner walls of the first semi-ring 1 and the second semi-ring 2 are respectively embedded with arc-shaped circumferential cutting blades 8. The distal ends of the two semi-rings are provided with connecting sleeves 9, which are rotatably connected by limiting shafts 10, making it convenient for the operator to hold and operate.

[0032] Furthermore, the stepped grooves 6 arranged in a stepped pattern cooperate with the locking block 5 to achieve precise control of the locking force. The locking teeth 7 are located on the opposite sides of the first limiting block 3 and the second limiting block 4. When the stapler is closed, the serrated locking teeth 7 mesh with each other to prevent horizontal displacement during the operation. The integrity of the stapler is checked to ensure that the circumferential cutting edge 8 is undamaged and that the guide bevel of the locking block 5 facilitates insertion into the stepped grooves 6.

[0033] The specific working principle is as follows: when cutting the foreskin, the inner ring 12 and the outer ring 11 cooperate with each other. The outer ring 11 includes the first half ring 1 and the second half ring 2. In this embodiment, we mainly talk about the relevant structure of the outer ring 11.

[0034] Specifically: Before using the first half-ring 1 and the second half-ring 2, first open the first half-ring 1 and the second half-ring 2 around the limiting shaft 10, put the patient's foreskin into the stapler, and adjust the position of the foreskin so that the part to be removed is below the circumferential cutting edge 8; then rotate the second half-ring 2 so that the first half-ring 1 and the second half-ring 2 gradually close, insert the locking block 5 on the second limiting block 4 into the stepped locking groove 6 of the appropriate height on the first limiting block 3. At this time, the locking teeth 7 on the first limiting block 3 and the second limiting block 4 engage with each other, completing the locking and fixing of the outer ring 11 of the stapler; make the circumferential cutting edge 8 close to the foreskin, and the inner ring also close to the other side of the foreskin. The foreskin should be placed between the inner ring and the outer ring. Within 2-4 weeks, the foreskin relies on the pressure of the inner and outer rings to cut off the blood supply, and the excess foreskin necroses, completing the cutting. It should be noted that the foreskin is completely removed by clamping it with the inner and outer rings until it necroses, which takes time. After the surgery, the inner and outer rings are placed on the foreskin and penis until the foreskin in the designated area necroses and the wound heals before the inner and outer rings are removed.

[0035] This embodiment also provides a method for applying a stepped locking disposable circumcision stapler, characterized by the following specific steps: (1) Open the stapler: rotate the first half ring 1 and the second half ring 2 around the limiting shaft 10 to separate them and form an open state; (2) Placement of foreskin tissue: The patient's foreskin is put into the stapler and the position is adjusted so that the part to be removed is below the circumferential cutting edge 8, that is, placed between the outer ring 11 and the inner ring 12; (3) Close and lock the outer ring: Rotate the second half ring 2 to close it with the first half ring 1, that is, close the outer ring 11. By embedding the card block 5 into the stepped card slot 6, the card teeth 7 on the first limit block 3 and the second limit block 4 mesh with each other to achieve locking and complete the outer ring locking. (4) Cutting: The part to be cut is tightly clamped between the outer ring 11 and the inner ring 12. After a period of blood loss and necrosis, the cutting is completed. That is, within 2-4 weeks, the foreskin relies on the pressure of the inner ring 12 and the outer ring 11 to cut off the blood supply, and the excess foreskin necroses, thus completing the foreskin cutting and anastomosis.

[0036] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
