Description

Technical Field

[0001] This utility model belongs to the technical field of circumcision staplers, specifically a novel circumcision stapler. Background Technology

[0002] Phimosis or paraphimosis is a common physiological problem in men. Circumcision is an effective way to solve this problem. Traditional circumcision often involves manual excision and suturing, which is a complex procedure that requires a high level of skill from the surgeon, takes a long time, and is prone to complications such as bleeding, infection, and poor wound healing. With the development of medical technology, circumcision staplers have been gradually applied in clinical practice. These staplers use the inner and outer rings to cut and anastomose the foreskin, simplifying the surgical procedure and shortening the operation time.

[0003] However, existing circumcision staplers still have some problems in use. For example, when cutting the foreskin tissue, the foreskin tissue tends to slide between the inner and outer rings, leading to inaccurate cutting positions and affecting the surgical outcome. Furthermore, the blood flow blocking effect on the foreskin tissue is not ideal, which may increase the risk of postoperative bleeding. (Utility Model Content)

[0004] To overcome the above-mentioned defects, this utility model provides a novel circumcision stapler.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel circumcision stapler, comprising an inner ring and an outer ring. The inner ring supports the inner side of the foreskin, and the outer ring consists of a pair of interlocking outer ring buckles. A blunt blade is provided on the inner side of each outer ring buckle, and several protrusions are provided on one side of the blunt blade. During the process of fastening the outer ring buckle to the outer side of the inner ring, the protrusions can compress the foreskin tissue located on the outer side of the inner ring in front of the blunt blade, fixing it relative to the inner and outer rings. This prevents relative sliding when the blunt blade compresses the foreskin tissue against the outer wall of the inner ring and blocks blood flow to the foreskin. The protrusions on the side of the blunt blade on the inner side of the outer ring buckle effectively compress the foreskin tissue during locking of the outer ring, fixing it relative to the inner and outer rings, preventing slippage of the foreskin tissue during cutting, ensuring the accuracy of the cutting position, and improving the surgical outcome.

[0006] Specifically, the outer ring latch includes a main outer ring and a secondary outer ring, which are rotatably connected on one side and have interlocking locking teeth on the other side.

[0007] Specifically, the inner ring is annular, with a concave portion on its outer side wall, and also includes a silicone rubber gasket ring, which is sleeved on the concave portion and forms an integral part with the inner ring.

[0008] Specifically, one side extends outward to form an anastomosis portion, which can fit with the coronal sulcus. The anastomosis portion has a notch with chamfered edges around it, and the notch is used to place the frenulum of the penis.

[0009] Specifically, the anastomosis is inclined, with its inclination angle matching the coronal sulcus, and the notch corresponds to the position of the frenulum of the penis in the coronal sulcus.

[0010] Specifically, it also includes a thruster for connecting to the inner ring. The thruster includes a body and a thrust handle, which is integrally formed with the body and has anti-slip texture.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] The protrusion on the blunt blade side of the inner side of the outer ring lock can effectively compress the foreskin tissue when locking the outer ring, making it relatively fixed with the inner and outer rings, preventing the foreskin tissue from sliding during the cutting process, ensuring the accuracy of the cutting position, and improving the surgical effect.

[0013] The anastomosis of the inner ring fits snugly against the coronal sulcus and has a notch corresponding to the position of the frenulum of the penis, which can better adapt to the physiological structure of the penis, protect the frenulum of the penis during the operation and avoid damage;

[0014] The use of silicone rubber gaskets increases the friction between the inner ring and the foreskin tissue. At the same time, because silicone rubber is soft, it can reduce damage to the foreskin tissue and is beneficial to postoperative recovery. Attached Figure Description

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a novel circumcision stapler, including an inner ring 10 and an outer ring 20. The inner ring 10 is used to support the inner side of the foreskin. The outer ring 20 consists of a pair of interlocking outer ring buckles 201. A blunt blade 202 is provided on the inner side of the outer ring buckle 201. A plurality of protrusions 203 are provided on one side of the blade of the blunt blade 202. During the process of fastening the outer ring buckle 201 to the outer side of the inner ring 10, the protrusions 203 can press against the blunt blade 202 and be located on the inner side of the inner ring 10. The foreskin tissue outside the inner ring 10 is fixed relative to the inner ring 10 and the outer ring. This prevents relative sliding when the blunt blade 202 squeezes the foreskin tissue against the outer wall of the inner ring 10 and blocks blood flow to the foreskin. The protrusion 203 on one side of the blunt blade 202 inside the outer ring lock 201 can effectively squeeze the foreskin tissue when locking the outer ring 20, fixing it relative to the inner ring 10 and the outer ring 20. This prevents the foreskin tissue from sliding during the cutting process, ensures the accuracy of the cutting position, and improves the surgical effect.

[0025] Furthermore, the outer ring buckle 201 includes a main outer ring 204 and a secondary outer ring 205, which are rotatably connected on one side and have interlocking locking teeth on the other side. It can be understood that, in order to lock the main outer ring 204 and the secondary outer ring 205, a male buckle 206 is provided at the end of the main outer ring 204 and a female buckle 207 is provided at the end of the secondary outer ring 205. More specifically, the male buckle 206 and the female buckle 207 are provided with three rows of teeth 209, that is, the main outer ring 204 and the secondary outer ring 205 are engaged to the maximum extent that all three rows of teeth 209 are engaged, at which time the inner ring 10 fits the outer ring most tightly. Similarly, the main outer ring 204 and the secondary outer ring 205 are engaged to the minimum extent that one row of teeth is engaged, at which time the engagement is the lowest and the inner ring 10 fits the outer ring most loosely. Therefore, the tightness of the fit between the inner ring 10 and the outer ring can be adjusted according to the actual situation to ensure the comfort of the patient.

[0026] Furthermore, after the male buckle 206 and female buckle 207 engage with the main outer ring 204 and the secondary outer ring 205, a prying groove 208 will remain on the male buckle 206. It can be understood that the prying groove 208 is elongated, and its length direction is perpendicular to the orientation of the three rows of teeth 209 on the male buckle 206 or the female buckle 207. Therefore, when the prying groove 208 is pried open, the teeth on the male buckle 206 move along the surface of the teeth on the female buckle 207 until the two disengage, thus separating the main outer ring 204 and the secondary outer ring 205.

[0027] Furthermore, the inner ring 10 is annular, with an inner recess 101 on its outer side wall, and also includes a silicone rubber gasket 30. The silicone rubber gasket 30 is fitted onto the inner recess 101 and forms an integral part with the inner ring 10. It can be understood that when the outer ring is in the engaged state, the blunt knife 202 abuts against the silicone rubber gasket 30. Therefore, the silicone rubber gasket 30 and the blunt knife 202 squeeze each other, blocking blood flow and more effectively preventing bleeding during or after the operation.

[0028] Furthermore, it also includes a thruster 40, which is used to connect the inner ring 10. The thruster 40 includes a body 401 and a thrust handle 402. The thrust handle 402 is integrally formed with the body 401, and the thrust handle 402 is provided with anti-slip texture 403.

[0029] In practical use: After the inner ring 10 is put on, the pusher 40 is inserted into the inner ring 10, so that medical staff can push and adjust the inner ring 10 through the push handle, which makes it convenient for medical staff to observe the treatment site. Then, the medical staff rotates the main outer ring 204 and the secondary outer ring 205 to make them lock together, separating the tissue to be removed from the tissue to be preserved. This causes the blunt blade 202 on the inner side of the main outer ring 204 and the secondary outer ring 205 to squeeze the foreskin. Before this, the protrusion 203 will fix the foreskin tissue first, forming multiple fixing points between the inner ring 10 and the outer ring. Due to the effect of the fixing points, when the blunt blade 202 squeezes the foreskin tissue, the foreskin tissue will not slide relative to the inner ring 10 and the outer ring. Then the cutting surgery can be performed. Example

[0030] The inner ring 10 extends outward from one side to form an anastomosis portion 102, which can fit with the coronal sulcus. A notch 103 is provided on the anastomosis portion 102, and the notch 103 is chamfered around its perimeter. The notch 103 is used to place the penile frenulum to avoid overcutting of the frenulum and surrounding tissues, which could lead to complications such as hematoma, edema, and slow healing.

[0031] Furthermore, the anastomosis portion 102 is inclined, and its inclination angle matches the coronal sulcus. The notch 103 corresponds to the position of the frenulum of the penis in the coronal sulcus. It can be understood that the inclined setting of the anastomosis portion 102 allows the remaining foreskin after removal to fit better with the coronal sulcus, avoiding over-cutting or under-cutting, and improving postoperative aesthetics and comfort.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
