Before the device is used, medical personnel firstly sleeve the right side of the shell 4 on the connector 2 so as to enable the shell 4 to be tightly matched and connected with the sampling tube 1, meanwhile, in the tight matching process, the shell 4 forms extrusion force on the blocking blocks 303, further, two blocking blocks 303 are enabled to move towards each other, the first spring 302 is synchronously deformed, the communication hole 304 is coincided with the air suction hole 301, then the sampling needle 13 is sleeved on the right side of the sampling tube 1, in the process that the sampling needle 13 sleeves the sampling tube 1, the sampling needle 13 carries out extrusion force on the closing block 703 so as to enable the closing block 703 to move back along the direction of the groove 701, the second spring 702 is synchronously deformed, at the moment, the closing block 703 carries out clamping force on the outer wall of the sampling needle 13 under the action of the resilience force of the second spring 702 so as to enable the sampling needle 13 to be stably connected with the sampling tube 1, then, the medical personnel can hold the sampling tube 1 by hands, under the assistance of the imaging device in the prior art, the sampling needle 13 is punctured into a breast tumor part of a patient, then the vacuum pump 14 is started through the switch 16, effusion in the breast tumor passes through the sampling needle 13 through the sampling tube 1 through the suction force of the vacuum pump 14, and is discharged into the shell 4 through the mutually overlapped suction hole 301 and the communication hole 304, after the effusion is completely sucked, medical personnel firstly close the vacuum pump 14 through the switch 16 and then manually push the handle 10, so that the handle 10 drives the connecting rod 8 and the handle 901 to move from left to right along the direction of the sampling tube 1, when the handle 901 is contacted with the left side of the sampling needle 13, the sampling needle 13 performs extrusion force on the handle 901 under the action of the pushing force, and further the handle 901 in an unfolded state is stored and processed, the synchronous third spring 902 is deformed, and the aim is that the sampling needle 13 smoothly penetrates through the handle 901 and the tool bit 903 and moves into the breast tumor part, after the knife handle 901 is moved out of the sampling needle 13, the knife handle 901 is reset under the action of the resilience force of the spring 902, the knife handle 901 is in an unfolded state, the knife head 903 at the knife handle 901 is attached to the inner wall of the breast tumor, the handle 10 is rotated to drive the connecting rod 8, the knife handle 901 and the knife head 903 to rotate, the purpose is to enable the knife head 903 to cut the breast tumor tissue, simultaneously, the vacuum pump 14 is opened in the cutting process, the cut breast tumor tissue and effusion generated by cutting are sucked into the sampling tube 1 through the suction force of the vacuum pump 14, the effusion can be sucked into the shell 4 through the action of the filter screen 5, the breast tumor tissue stays in the sampling tube 1, after the suction is finished, medical personnel firstly close the control valve 6 to prevent the effusion from flowing into the sampling tube 1, the vacuum pump 14 is turned off again, and then the handle 10 is pulled leftwards, at this time, the right side of the sampling needle 13 applies extrusion force to the tool shank 901, so that the two tool shanks 901 rotate oppositely along the right direction of the connecting rod 8, and the purpose is to place the tool shanks 901 in a storage state, smoothly move the sampling needle 13 from the inside of the sampling needle 13 into the sampling tube 1, and then move the sampling needle 13 out of the patient. At this time, the medical staff can separate the sampling tube 1 from the sampling needle 13 and the housing 4, and the closing block 703 is moved in the direction of avoiding the groove 701 by the resilience of the second spring 702, then the right side of the sampling tube 1 is blocked, the blocking block 303 moves backwards under the action of the resilience force of the first spring 302, further, by displacing the suction hole 301 and the communication hole 304 to close the end of the connector 2, the above-described configuration, the sample in the sampling tube 1 can be sealed, so that medical staff can conveniently inspect the breast tumor sample subsequently, then the medical staff can move the sampling tube 1 to the inspection position, firstly press the elastic sheet 1201 downwards to make the elastic sheet 1201 separate from the inside of the locking groove 1202, the fixed state of the extraction window 11 is cancelled, and then the extraction window 11 is slid leftwards, so that the breast tumor tissue is extracted through the opened extraction window 11. Afterwards medical personnel can open control valve 6, pass through control valve 6 discharge external with the hydrops in casing 4, afterwards again to casing 4 carry out disinfection processing can, through above-mentioned mode, can absorb breast tumor tissue hydrops at the uniform velocity, still can cut the massive tissue of breast tumor and be convenient for absorb, the breast tumor tissue and the hydrops after will absorbing simultaneously separate, the follow-up sample that detects of being convenient for provides sealed environment for the sample simultaneously, improve the sample success rate. The battery 15 is used for supplying energy to the device, and the vacuum pump 14 is preferably in the type of JFB 370-6A-01.
