Wherein, the injection port 85 or the suction liquid inlet 510 of the automatic suction controller 5 is connected with one end of the plastic extension tube 3 through the joint 4, the liquid inlet 87 is provided with a rubber plug 811, and the suction liquid outlet 511 is connected with the suction liquid storage bag 7 through the pipeline 6. The input end of the suction electromagnetic valve 57 is communicated with the suction liquid inlet 510, and the output end of the flow sensor 59 is communicated with the suction liquid inlet 510. The display module 51, the key module 52 and the USB interface 53 are arranged outside the shell of the automatic suction controller 5, the display module 51 is an LCD display screen, and the microprocessor 54 is a single chip microcomputer. The injection cavity 84 is installed in the automatic injection device 8 through the injection cavity mounting seat 88, and the micro electric push rod 81 is installed in the automatic injection device 8 through the push rod front mounting seat 89 and the push rod rear mounting seat 810. The head of the hollow metal needle head 1 is arc-shaped, and the plastic handle 2 wraps the tail end of the hollow metal needle head 1.

The working principle is as follows:

before use, if it is desired to inject a drug into the abdominal cavity, the prepared drug is first inserted into the rubber plug 811 through the needle and then injected into the injection cavity 84. Then the joint 4 is arranged at the injection port 85, and then the plastic extension tube 3, the plastic handle 2 and the hollow metal needle 1 are arranged in sequence. When the injection operation is required, the microprocessor 54 controls the micro electric push rod 81 and the injection solenoid valve 86 to act only by pressing the injection function key of the key module 52, at this time, the injection solenoid valve 86 is closed, the micro electric push rod 81 is pushed forward slowly, and the piston 83 is driven to inject the medicine in the injection cavity 84 into the abdominal cavity through the injection port 85 and finally through the hollow metal needle 1.

When liquid (such as bile or blood) in the abdominal cavity needs to be sucked, the connector 4 is arranged on the suction liquid inlet 510, then the plastic extension tube 3, the plastic handle 2 and the hollow metal needle head 1 are sequentially arranged, and the hollow metal needle head 1 is punctured into the lumen of the vessel. Then, by operating the suction function key of the key module 52, the microprocessor 54 controls the suction solenoid valve 57 to open, controls the micro suction pump 58 to suck, and the suction liquid enters the suction liquid storage bag 7 through the suction liquid outlet 511, flows through the pipeline, detects the flow rate through the flow rate sensor 59, and displays the suction value on the display screen. When the suction reaches the preset value, the microprocessor 54 controls the suction solenoid valve 57 to close, controls the micro suction pump 58 to close, stops the suction, and simultaneously the voice module prompts the end of the suction. In addition, the doctor may temporarily stop the suction operation according to the actual operation of the button.

The USB interface is a charging port of the whole device and can be externally connected with a power supply to charge the battery module. Because foretell injection, suction function all realize automatic suction through the operation button operation, have reduced manual operation's burden, only need be absorbed in the operation to the controller after the doctor has installed outside pipeline, avoid manual operation to appear touching the pipeline easily and lead to the joint to fall, take place the problem of liquid pollution. And the amount of the suction is intelligently controlled, and the numerical value can be displayed, so that doctors can know the suction condition conveniently. Whether the punctured vessel is a bile duct or a blood vessel is determined according to whether bile or blood is extracted.
