Abstract:
In order to control the pressure in an abdominal cavity of a patient and a pressure in a hollow organ, a medical system includes: a first pressure sensor for measuring the pressure of a gas in the abdominal cavity; a first port for insufflating and evacuating the abdominal cavity; a second pressure sensor for measuring the pressure of a gas in the hollow organ; a second port for insufflating and evacuating the hollow organ; an air supply apparatus connected to the second port for controlling the air supply and evacuation based on the output by the first and second pressure sensors; a third port connected to the second pressure sensor in the air supply apparatus; an endoscope connected to the air supply apparatus; a pneumoperitoneum needle connected to the first port; and a puncture needle connected to the second port.
