[0031] Specifically: one side of the inner cavity of the rotator 2 is movably connected to one side of the surface of the negative pressure cylinder 1. When in use, the liquid storage barrel 4 is connected to the surface of the drainage pipe 11 through the threaded connection of the connecting port 13, so that the scraped tissue and liquid are collected. There are two fixing blocks 5 to facilitate the fixation of the electric vacuum pump 6. One end of the first air pipe 7 extends to the outside of the negative pressure cylinder 1, and the second air pipe 8 is located on one side of the inner cavity of the negative pressure cylinder 1 to form a negative pressure state inside the negative pressure cylinder 1. The air outlet pipe 9 and the first one-way valve 10 ensure that the gas generated by the piston cover 18 will not be blown into the patient's uterine cavity when it is reset, so as to prevent harm to the patient. The tissue and liquid sucked into the negative pressure cylinder 1 can be drawn into the liquid storage barrel 4 through the second one-way valve 12 and the drainage pipe 11. The connecting port 13 can connect the drainage pipe 11 and the liquid storage barrel 4. Specific embodiment 2

[0033] See also Figure 1-5 On the basis of the specific embodiment 1, the scraping and suction member includes a disassembly and assembly port 14, which is opened on one side of the rotator 2. The inner cavity of the disassembly and assembly port 14 is threadedly connected to a scraping spoon handle 15, one end of the scraping spoon handle 15 is fixedly connected to a scraping spoon head 16, and the inner cavity of the scraping spoon handle 15 is connected to a suction tube 17. One end of the suction tube 17 extends to the inner cavity of the scraping spoon head 16, and the other end of the suction tube 17 extends to the inner cavity of the negative pressure cylinder 1. The inner cavity of the negative pressure cylinder 1 is slidably connected to a piston cover 18, and a sealing ring is fixedly connected to the surface of the piston cover 18. The liquid storage barrel A filter plate 19 is fixedly connected to the inner cavity of the rear cover 3. One side of the surface of the liquid storage barrel 4 is connected to a discharge pipe 20, and a valve is provided on the surface of the discharge pipe 20. A controller 21 is fixedly connected to the top of one side of the rear cover 3. The input end of the electric vacuum pump 6 is electrically connected to the output end of the controller 21 in a one-way manner. A circular hole is provided in the inner cavity of the rear cover 3. One end of the first air pipe 7 extends to the outside of the rear cover 3 through the inner cavity of the circular hole. A threaded groove is provided on one side of the surface of the scraper handle 15. One end of the scraper handle 15 is threadedly connected to the inner cavity of the disassembly and assembly port 14 through the surface of the threaded groove.

[0034] Specifically, the suction tube 17 is arranged in the inner cavity of the scraper handle 15, and its two ends are respectively connected to the scraper head 16 and the outside of one end of the scraper handle 15, so as to absorb the tissue and liquid inside the uterine cavity. The tissue and liquid are drawn into the negative pressure cylinder 1 through the suction tube 17 for subsequent collection. The movement of the piston cover 18 can generate negative pressure inside the negative pressure cylinder 1, thereby adsorbing tissue and liquid. When the piston cover 18 moves in the opposite direction, the piston cover 18 can be reset, and the pressure generated when the piston cover 18 is reset is discharged through the air outlet pipe 9 and the first one-way valve 10. The disassembly port 14 can connect and disassemble the rotator 2 and the scraper handle 15, so as to facilitate cleaning of the scraper head 16 and the inside of the negative pressure cylinder 1.

[0035] The piston cover 18 is the main device for generating negative pressure inside the negative pressure cylinder 1. The piston cover 18 is driven to move by the electric vacuum pump 6, so that negative pressure is generated inside the negative pressure cylinder 1. The sealing ring is fixed on the surface of the piston cover 18, so that the surface of the piston cover 18 is sealed with the inner cavity of the negative pressure cylinder 1. The filter plate 19 is fixed to the inner cavity of the liquid storage barrel 4, dividing the inner cavity of the liquid storage barrel 4 into two parts. The filter plate 19 can separate the tissue and liquid into two parts for separate collection. The discharge pipe 20 is connected to the bottom of one side of the inner cavity of the liquid storage barrel 4. Its main function is to discharge and collect the liquid. The controller 21 can control the electric vacuum pump 6, thereby controlling the movement rate of the piston cover 18 and the speed of scraping and sucking the tissue and liquid to prevent the patient from feeling uncomfortable due to too fast speed and the scraping and sucking being not clean due to too slow speed. The circular hole connects the first trachea 7 with the outside world, which is convenient for the electric vacuum pump 6 to absorb and release gas. The scraper handle 15 and the rotator 2 are connected by the threaded groove, which is convenient for disassembly and assembly of the scraper head 16 for use and cleaning.

[0036] The working principle of the utility model is as follows: when continuous scraping and suctioning of the uterine cavity for artificial abortion is required, first, the scraper handle 15 is screwed into the connecting port 13 through the threaded groove, so that the rotator 2 is connected to the scraper head 16, and then the scraper head 16 is inserted into the uterine cavity to be scraped and suctioned, and then the rotator 2 is rotated, the rotator 2 drives the scraper handle 15 to rotate, and the scraper handle 15 drives the scraper head 16 to rotate, and the scraper head 16 scrapes out the tissue in the uterine cavity;

[0037] After the tissue is scraped out, the electric vacuum pump 6 can be started through the controller 21. The electric vacuum pump 6 generates negative pressure in the negative pressure cylinder 1 through the first air pipe 7 and the second air pipe 8, so that the piston cover 18 moves. The piston cover 18 moves toward the rear end of the inner cavity of the negative pressure cylinder 1, so that the suction tube 17 adsorbs the tissue and liquid inside the uterine cavity. When doing the equipment work, the drainage pipe 11 is connected with the disassembly and assembly port 14 at the top of the liquid storage barrel 4 so that the tissue and liquid can be collected in the liquid storage barrel 4. When the tissue and liquid are sucked into the negative pressure cylinder 1, the tissue and liquid are drawn into the liquid storage barrel 4 through the drainage pipe 11 and the second one-way valve 12. When the tissue and liquid are collected in the liquid storage barrel 4, the tissue and liquid are separated by the filter plate 19, and finally the liquid is discharged and collected through the discharge pipe 20 and the valve, the connecting port 13 is separated from the drainage pipe 11, and the tissue is discharged and collected, thereby completing the scraping and suction work of artificial abortion.
