Description

FIELD OF THE INVENTION

The present invention relates to surgical devices, particularly to a circumcision apparatus and more particularly to a B-type valgus circumcision stapler.

BACKGROUND OF THE INVENTION

Refer to the B-type valgus circumcision stapler. The redundant prepuce or phimosis is one of the causes of male urinary system infections and sexually transmitted diseases. The redundant prepuce or phimosis can cause urinary tract infections, resulting in chronic prostatitis, with a series of symptoms, such as pains in back and waist, impotence and premature ejaculation. Therefore, the removal of the redundant prepuce is a good way to prevent these diseases.

Traditionally, surgical removal of the phimosis or redundant prepuce has the main technical points of removal of excess prepuce, hemostasis, and apposition suture of cut edges to skin. A postoperative patient cannot move around, suffers unbearable pain in each change of ointment and endures huge pain when stitches are taken out finally. In addition, incomplete ligating hemostasis will cause prepuce hematoma, thus requiring a surgical treatment again. Furthermore, since the prepuce removal and the hemostasis processes are performed separately, the surgery time is prolonged, and the patient's panic is exacerbated.

A therapeutic method of applying a laser and high-frequency electric surgical knife technology to circumcision has been developed at present. Although this therapeutic method substitutes for scissors cutting and makes a bleeding spot coagulated, the patient's tissues will be burnt and susceptible to infection.

Then, a circumcision device was developed in this field. In the circumcision device, a prepuce incision is sutured using a suturing nail in one step. However, during a surgery using a conventional built-in circumcision stapler in the prior art, a front prepuce and most of a penis are exposed outside, so that the prepuce and the penis are vulnerable to injury or infection. A portion above a prepuce clamping portion of the built-in circumcision stapler is located outside the circumcision stapler, while a U-nail suturing position is located at the top of the circumcision stapler. Once hemorrhage caused by instrument failure or misoperation occurs, a patient is likely to be infected to cause a surgical accident. The built-in circumcision stapler has a built-in circumcision knife, and thus carries out cutting inside and nailing at periphery. In case of a redundant prepuce or the like, the possibility of cutting of overlapped tissues is high, causing pain and risks. In addition, if circumcision and hemostasis with U-nails are performed as soon as appropriate clamping is realized only through cooperation between an upper cover (upper comprehensive cover) and a lower cover (lower comprehensive cover/connecting cover) as well as between an inner ring (prepuce fixing hoop) and an inner comprehensive cover (U-nail top ring and/or thimble guide block), a prepuce blood vessel cannot be accurately positioned as a built-in nail groove is not visible. As a result, the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during the surgery, so that a hemostasis effect is poor. Even, the head of the U-nail may be just hammered into the blood vessels, resulting in a surgery risk as hemostasisis not punctual. Moreover, in the existing technology, as the U-nail is directly hammered into the prepuce, the U-nail is likely to adhere with the prepuce and even U-nail cannot peel off punctually as the U-nail deeply penetrates into the prepuce in a process of waiting for necrosis and defluvium of the prepuce and peeling off of the U-nail after the surgery, causing severe pain to the patient.
