The adsorption mechanism moves upward, drives the transmission mechanism, and drives the temporary storage mechanism. The adsorption mechanism detaches the living tissue, which falls into the temporary storage mechanism for temporary storage.

[0020] The present invention has the following beneficial effects:

[0021] This invention enables convenient sampling of multiple live tissues from different parts of the human body, eliminating the need to waste time storing the live tissues in other containers after each sampling. By controlling the rubber pusher and control tube, two cutting blades can be driven to cut the live tissue, facilitating its detachment from the body and subsequent adsorption. This eliminates the need for cutting blades, improving surgical efficiency and convenience. Furthermore, after the adsorption tube adsorbs the live tissue and moves upward, it automatically drops the tissue into one of the sample storage boxes. During each sampling, the pressure of the force plate on the self-resetting air piston rod causes the airbag to gradually expand, gradually connecting the third permanent magnet with different fourth permanent magnets. This allows different sample storage boxes to move to the right sequentially after adsorption sampling of different live tissues, temporarily storing the tissues and preventing them from falling out or becoming contaminated.

[0042] In an optional embodiment of the invention, the blocking block 15 is made of medical-grade silicone rubber. Medical-grade silicone rubber is non-toxic and harmless, and its softness allows it to effectively block the fourth channel 12.

[0043] In an optional embodiment of the present invention, the cutting blade 50 is made of one of high-speed steel, tungsten steel, or tungsten carbide. High-speed steel, tungsten steel, and tungsten carbide are all materials used in the manufacture of medical knives, and all possess good corrosion resistance, hardness, and toughness.

[0044] A method for using a biopsy device suitable for interventional operating rooms includes the following steps:

[0045] Bring the outer shell 1 close to the living tissue 53, push the adsorption mechanism downward, and use the cutting mechanism to cut the living tissue 53, detaching the living tissue 53 from the human body. The adsorption mechanism moves upward, driving the transmission mechanism, which in turn drives the temporary storage mechanism. The adsorption mechanism detaches the living tissue 53, which then falls into the temporary storage mechanism for temporary storage.

[0046] Implementation process: When the living tissue 53 is attached to the human body and needs to be removed for examination, the outer shell 1 is brought close to the living tissue 53, the rubber head 9 is flattened, and the control tube 10 is pushed down. When the force plate 18 presses down on the self-resetting air piston rod 40, the self-resetting air piston rod 40 inflates the airbag 34 through the air transmission tube 37. The gas at the first one-way valve 36 can only flow from the air transmission tube 37 to the airbag 34, and the gas at the second one-way valve 38 can only flow from the outside to the air transmission tube 37. The airbag 34 inflates and expands, pushing the straight tooth plate 22 to the left, thereby causing the third permanent magnet 23 and the rightmost fourth permanent magnet 24 on the straight tooth plate 22 to... Magnetic connection, the force-applying plate 18 presses down on the pressure plate 41, thereby driving the pressure rod 42 and the two pressure strips 43 to move downwards. This causes the two rollers 44 to push the two wedge-shaped transmission blocks 45 to overcome the elastic force of the third elastic element 47 and move closer together. The two push plates 46 move closer together, thereby pushing the two cutting rods 48 to rotate around the rotating shaft 49. The two cutting blades 50 cut the living tissue 53. At this time, the lower end of the adsorption tube 11 abuts against the living tissue 53. The living tissue 53 blocks the lower end of the adsorption channel 52. The rubber press head 9 is released, and the living tissue 53 is adsorbed under the action of negative pressure in the adsorption tube 11. The control tube 10 is moved upwards, and the pressure plate 41 loses the force-applying plate. After the pressure of 18 is applied, the piston rod moves upward and resets. The two wedge-shaped transmission blocks 45 move away from each other and reset under the elastic force of the third elastic element 47. The two cutting rods 48 reverse and reset under the elastic force of the fourth elastic element 51. The self-resetting air pump piston rod 40 moves upward and resets under the action of the reset spring. The first one-way valve 36 prevents the gas in the air bag 34 from flowing back into the air transmission pipe 37. The second one-way valve 38 allows the outside gas to enter the air transmission pipe 37, thus enabling the self-resetting air pump piston rod 40 to move upward and reset smoothly. When the transmission tooth 19 on the adsorption tube 11 meshes with the spur gear 21, it will drive the spur gear 21 to rotate counterclockwise, thereby causing the spur tooth plate 22 and the third permanent magnet 23 to move downward. Iron 23 drives the fourth permanent magnet 24, slider 25, and protrusion 26 to move down. Protrusion 26 slides in the uppermost inclined strip hole 28, thereby driving the uppermost linkage bar 30 and sample storage box 31 to move to the right. The sample storage box 31 moves to the right below the adsorption tube 11. At this time, the first permanent magnet 16 moves to the left of the second permanent magnet 20. Under the magnetic attraction of the second permanent magnet 20, the first permanent magnet 16 overcomes the elastic force of the first elastic element 17 and moves to the right, thereby causing the blocking block 15 to detach from the inner wall of the fourth channel 12. The fourth channel 12 changes from a blocked state to a connected state. After the living tissue 53 loses its attraction, it falls into the uppermost sample storage box 31 for temporary storage.

[0047] When it is necessary to sample the next living tissue 53, squeeze the rubber head 9 again to move the control tube 10 down. The transmission gear 19 drives the spur gear 21 to rotate clockwise, thereby moving the protrusion 26 up to reset the magnetic connection between the third permanent magnet 23 and the fourth permanent magnet 24. This allows the fourth permanent magnet 24 to move up and down, and the third permanent magnet 23 to move smoothly left and right. The protrusion 26 drives the uppermost transmission plate 27, the linkage bar 30, and the sample storage box 31 to move left to reset. The first channel 4 can prevent the living tissue 53 in the sample storage box 31 from being contaminated or falling out. When the force plate 18 presses down the self-resetting air piston rod 40 again, the airbag 34 expands more, thereby pushing the spur plate 22 to move left. The third permanent magnet 23 moves to the top of the middle fourth permanent magnet 24 and connects magnetically with the middle fourth permanent magnet 24, so that the next living tissue 53 can fall into the middle sample storage box 31 using the same principle.

[0048] The principle of causing the next living tissue 53 to fall into the bottom sample storage box 31 is the same as described above, and will not be repeated here.

[0049] This device is suitable for many diseases that require sampling of living tissue, such as tumors, condyloma acuminata, and swollen lymph nodes. It is applicable to multiple scenarios, such as interventional operating rooms and outpatient clinics.

[0050] This invention enables convenient sampling of multiple live tissues 53 from different parts of the human body, eliminating the need to waste time storing the live tissues 53 in other containers after each sampling. By controlling the rubber pusher 9 and the control tube 10, two cutting blades 50 can be driven to cut the live tissues 53, allowing them to detach from the body and be subsequently adsorbed smoothly without the need for cutting blades, thus improving surgical efficiency and convenience. Furthermore, after the adsorption tube 11 adsorbs the live tissues 53 and moves upward, it automatically drops the live tissues 53 into one of the sample storage boxes 31. During each sampling, the pressure plate 18 presses the self-resetting air piston rod 40, causing the airbag 34 to gradually expand, gradually connecting the third permanent magnet 23 with different fourth permanent magnets 24. This allows different sample storage boxes 31 to move to the right one by one after adsorbing and sampling different live tissues 53, temporarily storing the different live tissues 53, preventing them from falling out, and also preventing contamination of the live tissues 53.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
