(2) the ultrasonic probe is correspondingly and axially extended into the fixed sleeve, so that the ultrasonic probe is slowly arranged in the inner sleeve body, the fixed rubber ring is pinched by hands to stretch the fixed sleeve and the probe sleeve to the tail end of the ultrasonic probe, and the elastic fixed rubber ring, the inner wall of the fixed sleeve and the inner wall of the inner sleeve body are correspondingly attached to the periphery of the ultrasonic probe;
(3) observing whether bubbles exist between the ultrasonic probe and the fixed sleeve and between the ultrasonic probe and the sleeve body of the probe sleeve, if so, slightly pressing the bubbles out of the sleeve opening of the fixed sleeve by using a finger; if no bubble exists, performing the step (4);
(4) smearing 3-5 g of medical coupling agent at the anus of a patient for lubrication, slowly placing an ultrasonic probe and a probe sleeve into the anus of the patient, keeping a liquid inlet pipe and a liquid outlet pipe outside the patient until an ultrasonic imager can observe the depth of the corresponding rectum through the ultrasonic probe, and fixing the ultrasonic probe to prevent the ultrasonic probe from sliding out of the anus of the patient;
(5) closing a clamping device of a liquid outlet pipe of the liquid injection cavity, connecting an injector with a liquid inlet pipe of the liquid injection cavity through a connector, outwards pumping air in the liquid injection cavity for multiple times through the injector until a piston of the injector is difficult to outwards pull, and closing the clamping device of the liquid inlet pipe of the liquid injection cavity;
(6) after the physiological saline is extracted by the injector, the injector is connected with the connector of the liquid inlet pipe, the clamping device of the liquid inlet pipe is opened, the physiological saline is injected slowly into the liquid injection cavity, after the physiological saline is visible in the liquid outlet pipe, the connector of the liquid outlet pipe is placed into the container, the clamping device of the liquid outlet pipe is opened, the physiological saline flows into the container, and after the injector completely injects the physiological saline, the clamping devices of the liquid outlet pipe and the liquid inlet pipe are closed;
(7) observing an image generated by an ultrasonic imaging instrument connected with the ultrasonic probe, if the image has an unclear part, indicating that gas remains in the liquid injection cavity, and repeating the step (6) for a plurality of times to continue injecting the physiological saline into the liquid injection cavity until the image is clear; if the image is clear, indicating that no gas remains in the liquid injection cavity, performing step (8);
(8) and opening the clamping device of the liquid inlet pipe, continuously injecting normal saline into the liquid injection cavity for multiple times through the liquid inlet pipe by using the injector, continuously and slowly filling the liquid injection cavity with the normal saline, extruding the outer sleeve body by the normal saline to expand to generate tension, enabling the outer sleeve body to be tightly attached to the inner wall of the rectum intestinal canal, and injecting the normal saline until the ultrasonic probe scans the image generated by the ultrasonic imaging instrument is satisfied or the patient feels uncomfortable and stops.
9. The method for using the gas interference prevention device for the transrectal ultrasound probe according to claim 8, wherein in the step (8), when the rectum is scanned by the ultrasound probe, the position of the ultrasound probe is adjusted by swinging according to the angle to be detected, so as to obtain the required image on the ultrasound imager.
10. The use method of the device for preventing gas interference of the transrectal ultrasound probe according to claim 8, wherein the liquid inlet pipe and the liquid outlet pipe are both flexible pipes, the fixing sleeve and the probe sleeve are both made of rubber, and the connecting ring is made of rubber or soft plastic.
