The present invention relates to surgical devices, particularly to a circumcision apparatus and more particularly to a blood vessel docking apparatus of a built-in or valgus circumcision device; a built-in or valgus graduated circumcision device; a prepuce circumcision stapler with an indication device, which is, more particularly, of a built-in type and a valgus type; an operation-visible circumcision stapler.
Refer to the blood vessel docking apparatus of a built-in or valgus circumcision device. 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 process 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.
For the built-in type, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, in the prior art, a circumcision cover only cooperates with a comprehensive cover and the circumcision and U-nail hemostasis are performed after clamping is completed. Since the position of the nail groove disposed in the comprehensive cover is always invisible, the prepuce blood vessel cannot be accurately positioned, and the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during surgery. Thus, the surgical hemostasis effect is not good. Even the nail head of the U-nail may be right hammered into the blood vessel, and surgery risk is caused as blood cannot be punctually stopped.
For the valgus type, a circumcision device in which a prepuce incision is sutured using suturing nails at one time was developed in this field. However, in the prior art, a valgus circumcision device only adopts an upper cover and a lower cover cooperating with each other and an inner ring and an inner comprehensive cover cooperating with each other, and the circumcision and U-nail hemostasis are performed after clamping is completed. Since the position of the internally disposed nail groove is always invisible, the prepuce blood vessel cannot be accurately positioned, and the U-nail in the U-nail groove cannot accurately correspond to the prepuce blood vessel during surgery. Thus, the surgical hemostasis effect is not good, even the nail head of the U-nail may be right hammered into the blood vessel, and surgery risk is caused as blood cannot be punctually stopped.
Refer to the built-in or valgus graduated circumcision device. 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.

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.
For the built-in type circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves arranged in a comprehensive cover will be invisible once the cooperation of the comprehensive cover and a circumcision cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.
For the valgus circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves of an inner comprehensive cover in a lower cover will be invisible once the cooperation of an upper cover and the lower cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.

For the valgus prepuce circumcision device, a prepuce incision is sutured using suturing nails at one time. However, in the prior art, the positions of nail grooves of an inner comprehensive cover in a lower cover will be invisible once the configuration of the inner ring and the cooperation of an upper cover and the lower cover is completed. Therefore, U-nails in the U-nail grooves cannot accurately correspond to prepuce blood vessels during surgery, resulting in a poor surgical hemostasis effect. Even the nail heads of the U-nails may be just hammered into the blood vessels, resulting in a surgery risk as bleeding cannot be punctually stopped.
