PROBLEM TO BE SOLVED: To provide a device and a method for easily reaching direct solutions of problems concerning imperfect cardia sphincters by more precisely judging characteristics of a cuff formed by surgery near the interface between the esophagus and the stomach, and adjusting the cuff. according to the strength of the esophagus sphincters. SOLUTION: The calibrator 10 for the surgery of a bottom plica cuff has a pressure calibrator main body 13 and an entrance lead 14. An end of the entrance lead 14 on a patent's side can be connected to the pressure calibrator main body 13, and the other end of the entrance lead 14 has a means to operate the pressure calibrator main body 13 and to measure the pressure on the pressure calibrator main body 13. The cubic volume of the pressure calibrator main body 13 can be expanded to a prescribed volume, and the pressure calibrator main body may be preferably a balloon 3. In the outline of the pressure calibrator main body 13, an expansion set-in surface 16 is formed which can be directly surrounded by the tucked bottom of an internal organ at least when expanded. |
