Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a circumcision stapler. Background Art

[0002] The circumcision stapler is a medical device specifically used for male circumcision surgery. It can complete the surgery in a precise and efficient manner, reduce bleeding, reduce the risk of infection, and shorten postoperative recovery time.

[0003] When using a circumcision stapler, the surgical area must first be thoroughly disinfected and cleaned to ensure a sterile environment. Subsequently, the doctor will select the appropriate glans hood size based on the patient's specific situation and fix it in the appropriate position on the patient's penis. Next, the doctor will adjust the cutting depth and width of the cutting stapler to ensure that it cooperates with the glans hood to achieve the best state. Finally, the doctor activates the cutting stapler and completes the cutting and stapling steps in one go, achieving precise foreskin removal and rapid wound healing.

[0004] Since the penis size and shape vary among patients, it is necessary to prepare glans hoods of various sizes. If the glans hood is too large, it may cause the glans to shift or slip during surgery, affecting the surgical effect; if it is too small, it may cause discomfort or even pain to the patient.

[0005] At the same time, the existing glans hood still has some shortcomings in terms of comfort. Since the glans hood needs to fit tightly with the patient's penis and the patient needs to maintain a certain posture during the operation, the pressure and friction of the glans hood on the patient's skin can easily cause discomfort or pain to the patient.

[0034] An annular knife pad plate 901 is provided on the cover body 9. The annular knife pad plate 901 is arranged around the cover body 9. The knife pad plate is used to fix the skin to be cut so that the skin can be cut together with the annular cutting knife and the knife pad plate.

[0035] An trachea 11 is provided in the guide rod 10, and the trachea 11 and the guide rod 10 are parallel to each other. A cavity is provided on the cover body 9, and the cavity includes a cavity opening 902 and a cavity wall 903. The cavity wall 903 is arranged around the cavity opening 902, and an annular airbag 12 is provided at the cavity opening 902. The cavity wall 903 is covered with a soft film 904, and an annular support sheet 905 is provided on the cavity wall 903. The soft film 904 is connected to the cavity wall 903 through the annular support sheet 905. The soft film 904 and the cavity wall 903 are surrounded by an elastic cavity 906, and the annular support sheet 905 is located in the elastic cavity 906.
