Surgical steps of circumcision

2. Cleaning and disinfection: wash the local area with soapy water and salt water, and disinfect it with 1: 1000 bromogeramine; For phimosis, connect the syringe with the intravenous puncture needle, and inject the new geminium solution into the capsule for disinfection.

(1) Pick up the dorsal foreskin with hemostatic forceps; (2) Stripping the foreskin adhesion with a slotted probe.

3. The patients with narrow prepuce mouth and adhesion between prepuce and penis head were separated and adhered. First, the prepuce mouth was enlarged with hemostatic forceps, and then the middle part of the back edge was clamped with two hemostatic forceps (the distance between the two forceps was 0.2cm). Separate adhesion with slotted probe until the penis head is completely separated from the foreskin. Then clean the skin and penis head with sterile normal saline.

4. Design the incision, clamp 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. Cut off the inner and outer plates of foreskin along the exploratory groove with scissors for the dorsal incision, and cut the inner plate of foreskin to a position about 0.5cm away from the edge of the crown groove.

(3) Circumcision along the exploratory groove (4) Circumcision at the position 0.5cm away from the crown groove.

6. Incite the foreskin, align the inner and outer plates of the foreskin, pull out the hemostatic forceps and the tie behind the foreskin, and then review whether the incision of the outer plate of the foreskin is suitable as the incision of 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 upwards 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 penis back.

5] The foreskin at the lacing should be preserved. 6] Ligate superficial dorsal vein of penis to stop bleeding.

8. Use a thin thread to sew a needle on the back, abdomen and left and right sides of the circular incision. Ligation should not be too tight, so as not to damage 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.

(7) Suture the inner and outer panels, and (8) Fix vaseline gauze with suture.

9. Bandage: wrap a layer of vaseline gauze around the incision of the foreskin (the raw edge is folded inward), fix it with long suture, and then wrap several layers of gauze.
