To explore the feasibility and safety of the puncture protection device (independent patent) and the peelable catheter sheath entering peritoneal cavity along the umbilical margin.

Five cases of hydrocephalus were operated with the puncture protection device and the peelable catheter sheath entering peritoneal cavity along the umbilical margin. The safety of puncture and the reliability of catheter were observed under laparoscopic. After the success, 21 cases of hydrocephalus were used guided shunt tubes placed peritoneal cavity according to the above location and method and no guide at the same time.

They were all successful including 5 cases of the puncture under laparoscopic and 21 cases of the puncture no guide. The success rate of puncture is 100% and the average catheter time was 4 min. Abdominal puncture injury and abdominal surgical scar did not happen.

The operation has the advantage of a minimally invasive, safe, simple operation, less complication, which applied puncture protection device (independent patent) and the peelable catheter sheath entering peritoneal cavity along the umbilical margin.
