Prepare 1 before prepuce operation, the night before operation and the day of operation, and ask patients to clean this part. 2, complicated with foreskin, penitencis, need to choose drugs and local immersion treatment, surgery after inflammation subsided. Local anesthesia or cavernous anesthesia; Children can be given basic anesthesia.

Guiding opinions:

Operating steps 1, supine position. 2. Cleaning and disinfection: wash the local area with soapy water and salt water, and disinfect it with 1: 1000 bromogeramine disinfectant; For phimosis, connect the syringe with the intravenous puncture needle, and inject the new geminium solution into the capsule for disinfection. 3. To separate adhesion with narrow prepuce mouth and adhesion between prepuce and penis head, first enlarge the prepuce mouth with hemostatic forceps, and then clamp the middle part of the dorsal edge with two hemostatic forceps (the distance between the two forceps is 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. 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, use a curved scissors to cut along the edge about 0 from the crown groove. Cut off the right flap at the 5cm incision, 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. 8. sew with thin thread. First, 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. 9. Bandage Wrap a layer of vaseline gauze around the incision of the foreskin (the raw edge is folded inward), fix it with a long suture, and then wrap several layers of gauze. Operational considerations 1. In circumcision, the broken end of the blood vessel between the inner and outer plates often retreats to the proximal side, and it must be found and ligated, otherwise a large hematoma can be formed. 2, circumcision should not be too much, so as not to cause penile erection pain. Generally, the inner prepuce plate should be cut to about 0.5cm away from the coronary sulcus. You can't leave too little lace. The postoperative treatment was 1, and sedatives were taken before going to bed within 3~4 days after operation to prevent pain and bleeding caused by penile erection. Tell the patient not to wet the gauze when urinating.
