1. Patients should have an examination before operation. If there is no wrapping dermatitis or balanitis in the foreskin, they can have surgery. Before and on the day of operation, patients should be instructed to clean their private parts. 2, if complicated with foreskin, penitencis, need to choose drugs and local immersion treatment, such as inflammation subsided before surgery. Operation process of foreskin: 1, cleaning and disinfection. After the trousers are laid flat on the knees, the skin is prepared and scraped clean, then the part is washed with soapy water and salt water, and disinfected with1:1000 bromogeramine. Patients with phimosis are injected with bromogeramine into the skin bag for disinfection with a syringe connected with a venipuncture needle. 2, anesthesia. Local anesthesia or penile cavernous anesthesia, children can add basic anesthesia. Cover the glans with a glans cap after anesthesia. 3. Bonding separately. For those with narrow prepuce mouth and adhesion between prepuce and penis head, first use hemostatic forceps to enlarge prepuce mouth, then use two hemostatic forceps to pick up the middle part of the dorsal edge (the distance between the two pliers is 0.2cm), and use slotted probe to separate the adhesion until the penis head and penis head are completely separated. Then clean the skin and penis head with sterile normal saline. 4. Design the incision. Hold the foreskin strap with hemostatic forceps and lift the foreskin. Use the tip of the knife to make all marks at the position 0.5cm away from the distal edge of the coronal groove of the foreskin, and prepare a circular incision to prevent excessive resection. 5. Dorsal incision. Use scissors to cut off the inner and outer plates of foreskin along the exploratory groove, and the inner plate of foreskin should also be cut to about 0.5cm away from the edge of crown groove. 6. Remove the foreskin. Align the inner and outer plates of the foreskin, pull out the hemostatic forceps clamped at the back of the foreskin and the lace, and then check whether the incision of the outer plate of the foreskin is suitable for circumcision. If appropriate, cut off the right skin flap along the incision about 0.5cm away from the coronary sulcus with bending scissors, and then cut off the left side. The inner plate and the outer plate at the prepuce frenum can be left uncut, or more can be kept. 7. Stop bleeding. Retract the penis skin upward, and stop bleeding after revealing the bleeding point. Special attention should be paid to ligating the superficial dorsal vein of penis in the middle of dorsal side of penis. 8. suture. First, sew a needle on the back, abdomen and left and right sides of the circular incision with a thin thread, and the ligation should not be too tight, so as to avoid damage to the skin when tissue edema occurs. The suture is not cut short, and it is reserved for fixed dressing. Then sew 1 ~ 2 stitches every two stitches, and the stitches should come out near the knife edge. 9. bandages. Wrap a piece of vaseline gauze around the foreskin incision (the raw edge is folded inward), fix it with long suture, and then wrap several layers of gauze.
