the patient lies on the back, and the trachea cannula is taken from the central middle head position after full anesthesia takes effect. The lateral X-ray of the C-arm shows complete overlap of the bilateral bony auditory canals. The puncture point was selected 3cm outside the affected oral horn. Under the guidance of X-ray, the puncture needle is inserted towards the inner edge of the pupil on the same side and 3cm in front of the horizontal external auditory canal of the zygomatic arch. When the needle tip reaches the cranial base foramen ovale, the needle core is withdrawn, the catheter body 11 of the utility model is placed in the Meckel cavity along the puncture needle, and then the guide wire is withdrawn.
Firstly, the three stop valves are closed, a second injector 7 with the specification of 5ml is connected to the second side pipeline 33, then the second side valve 331 is opened, air is pumped outwards through the second injector 7, part of air in the catheter body 1 is pumped into the second injector 7, then the second side valve 331 is closed, and the second injector 7 is taken down and is exhausted; the above steps are repeated until the air cannot be pumped out, and finally the second side valve 331 is closed to prevent the external air from entering the catheter body 1. Because the gas in the catheter body 1 is pumped out, a low-pressure environment is formed in the catheter at the moment, and the influence of the gas on the operation pressure measurement is reduced.
Then the portable handheld digital pressure gauge and the first injector 6 with the specification of 2ml are taken, the contrast medium is extracted from the first injector 6, then the first injector 6 is connected to the first side pipeline 32, the pressure measuring pipe 34 is sleeved on the pressure measuring interface 5 of the portable handheld digital pressure gauge, and the portable handheld digital pressure gauge is zeroed.
Then, the first side valve 321 and the main valve 311 are opened, the balloon 2 is inflated with the non-ionic contrast agent Omnipaqne under the X-ray monitoring, the contrast agent enters the main pipeline 31 and the catheter body 1 through the first side pipeline 32, and the contrast agent flows to the front end of the catheter body 1 to inflate the balloon 2. The pressure change in the sacculus 2 is monitored by taking the pressure value change of the portable handheld digital pressure gauge, and after the sacculus 2 is expanded to a satisfactory pear-shaped shape, a side X-ray perspective image and the pressure value are collected. The saccule 2 is emptied after continuous pressing for 3min, and then the saccule and the puncture needle are withdrawn together. The change in pressure within the balloon from formation of the satisfactory "pear" shape to the final release of the balloon 2 was recorded (3 min).
