Description

Technical Field

[0001] The utility model relates to the technical field of circumcision suture devices, and more specifically, to a split type circumcision suture device gasket and a gasket device. Background Art

[0002] The circumcision stapler is a medical device used to assist in circumcision surgery. It can replace the manual cutting and suturing process of the human body. By using the stapler, the circumcision and suturing can be completed at one time, greatly shortening the operation time.

[0003] Most existing circumcision staplers use staplers to directly suture the incision after circumcision. There is a certain gap between the staplers, and there is no stapler to close the gap, which is easy to bleed and cause nail embedment (the new penis tissue embeds the staples in the penis tissue). In order to prevent the embedment of the staples, a layer of annular silicone pad is added between the staples and the foreskin. After suturing, the annular silicone pad is nailed to the foreskin to compress the wound and fill the gap between the staples, which reduces bleeding and prevents the occurrence of the embedment of the staples. After suturing, the annular silicone pad is broken into several small sections to prevent the annular silicone pad from tightening when the penis becomes larger after surgery, causing ischemic necrosis of the penis, scar formation or trauma.

[0004] The utility model with Chinese patent announcement number CN212281486U discloses a gasket and a gasket device for a foreskin suture device. The gasket of the foreskin suture device of the patent is provided with a plurality of arc segments and a plurality of U-shaped connecting segments, and the plurality of arc segments are connected by the plurality of U-shaped connecting segments to form a circle or a nearly circle (ring shape). The gasket of the foreskin suture device is embedded above the nail outlet on the nail magazine seat through the pad cavity and the groove on the nail magazine seat. The gasket of the foreskin suture device has two working modes: during the circumcision process, the U-shaped connecting segment bends inward, and the inner circumcision knife will cut off the U-shaped connection during the process of cutting the foreskin; if the U-shaped connection is not cut off, the U-shaped connection can be adaptively opened when the patient's penis becomes larger. Both working modes can prevent the annular silicone pad from tightening when the penis becomes larger after surgery, which may cause ischemic necrosis of the penis, scar formation or trauma;

[0005] Then, combined with the drawings in the specification, it can be seen that in the working mode of the above-mentioned circumcision suture gasket, the inner circumcision knife will cut off the U-shaped connection, and the cut end will inevitably be not smooth enough, which will cause discomfort to the patient after the operation and even cause new wounds. Although the retained U-shaped connection can adapt to the size of the penis, the U-shaped connection will still have a large lateral pulling force. Repeated pulling will make it difficult for the suture wound to heal and even cause the suture staples to loosen and fall off prematurely before the wound is healed. Utility Model Content

[0006] To overcome the above-mentioned defects of the prior art, the present utility model provides a split foreskin cutting and suturing device gasket and gasket device to solve the problems raised in the above-mentioned background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: A split foreskin cutting and suturing device gasket, comprising a plurality of arc-shaped gaskets.

[0017] The technical effects and advantages of the present utility model:

[0018] 1. First, in the present utility model, multiple arc-shaped gaskets are completely separated, and chamfering is performed around the arc-shaped gaskets to make the surface of the arc-shaped gaskets smoother. During the operation, it is not necessary to cut and separate the arc-shaped gaskets, reducing the damage to the foreskin caused by the incision edges and the resulting discomfort, and moderately reducing the lateral pulling force on the suturing staples when the penis enlarges after the operation, thereby reducing the problem of large-scale bleeding due to wound pulling and slow healing, and also reducing the problem of premature loosening and falling off of the suturing staples due to multiple pulls before the wound heals;

[0019] 2. The present utility model also combines the arc-shaped protrusions and the L-shaped block structure, and makes the second L-shaped block easier to fit into the U-shaped groove, facilitating installation and use. By setting the material of the arc-shaped gasket as a flexible plastic material, it is convenient for the arc-shaped gasket to produce elastic buffering as the penis enlarges, and it will not cause excessive bleeding due to excessive lateral pulling of the suturing staples, resulting in slow healing. This not only reduces the situation of premature loosening and falling off of the suturing staples due to multiple large-scale pulls before the wound heals, but also does not affect the natural falling off of the suturing staples after the wound heals;

[0020] In summary, through the mutual influence of the above multiple functions, it is not necessary to cut and separate the arc-shaped gasket during the operation, reducing the damage to the foreskin caused by the incision edges and the resulting discomfort, and appropriately reducing the lateral pulling amplitude on the suturing staples when the penis enlarges after the operation, thereby reducing the problems of wound pulling bleeding and slow healing, and also avoiding the premature falling off of the suturing staples, and exactly controlling the falling-off time of the suturing staples after the wound heals.
