In order to limit the fixed cylinder 3, the upper end of the fixed cylinder 3 extends out of the needle cylinder 1 and is coaxially provided with a fixed block 7, and the lower end face of the fixed block 7 can be contacted with the upper end face of the needle cylinder 1.

In order to move the push rod 4 up and down, the upper end of the push rod 4 extends out of the fixed cylinder 3 and is provided with a push plate 8 in the left-right direction, and the push rod 4 is sleeved with a spring 9 positioned between the push plate 8 and the fixed cylinder 3.

In order to carry out spacingly to push

pedal

8, 7 left and right sides of fixed block seted up opening draw-in groove 10 up respectively, the coaxial opening spacing groove 11 that faces outwards of seting up on fixed block 7, push pedal 8's the left and right sides is equipped with respectively and inserts the elastic rod 12 in its draw-in groove 10 that corresponds the side, the lower extreme of two elastic rods 12 can be relative or swing mutually and be equipped with stopper 13 respectively, stopper 13's up end can contact with the last lateral wall of spacing groove 11, stopper 13's lower terminal surface is the low outer high inclined plane of interior.

In order to enable the lower ends of the two elastic rods 12 to swing oppositely or oppositely, a rotating ring 14 is coaxially and rotatably connected in the limiting groove 11, arc-shaped plates 15 are coaxially arranged on the left side and the right side in the rotating ring 14 respectively, the thickness of each arc-shaped plate 15 is gradually reduced along the clockwise direction, and the inner edge surface of each arc-shaped plate 15 can be in contact with the limiting block 13 on the corresponding side.

In order to restore the rotating ring 14, a placing groove communicated with the limiting groove 11 is coaxially formed in the fixing block 7, a coil spring 16 is coaxially arranged in the placing groove, and the free end of the coil spring 16 is fixedly connected with the rotating ring 14.

In order to facilitate the observation of the depth of the needle cylinder 1 penetrating into the human body, the needle cylinder 1 is provided with scale marks 17.

When the utility model is used, the initial state of the device is that the cutting knife 6 is positioned below the sampling opening 2, the upper end surface of the limiting block 13 is contacted with the upper side wall of the limiting groove 11, and the reading of the set scale mark 17 is increased from bottom to top;

when the device is held by hand, the lower end surface of the needle cylinder 1 is an inclined surface, so that the needle cylinder 1 can be penetrated into a human body, meanwhile, the reading of the scale mark 17 which is level with the skin of the human body is observed, the reading of the scale mark 17 is the depth of the needle cylinder 1 penetrated into the human body, and when the reading of the scale mark 17 is consistent with the measured depth of a tumor, the penetration of the needle cylinder 1 is stopped;

when the needle cylinder 1 stops being pierced, the sampling opening 2 is positioned in the tumor, at the moment, the tumor tissue is extruded into the needle cylinder 1 from the sampling opening 2, the rotating ring 14 is rotated clockwise, the rotating ring 14 drives the arc-shaped plate 15 to rotate clockwise and enables the coil spring 16 to contract, along with the rotation of the rotating ring 14, the inner edge surface of the arc-shaped plate 15 is gradually contacted with the limiting block 13 on the corresponding side, because the thickness of the arc-shaped plate 15 is gradually reduced along the clockwise direction, along with the rotation of the arc-shaped plate 15, the arc-shaped plate 15 drives the limiting block 13 on the corresponding side to move inwards, and the limiting block 13 drives the lower ends of the two elastic rods 12;

when the upper end face of the limiting block 13 is separated from the upper side wall of the limiting groove 11, the push plate 8 drives the push rod 4 to move upwards under the action of the spring 9, the push rod 4 drives the cutting knife 6 to move upwards through the slide block 5, the cutting knife 6 cuts the tumor tissue in the needle cylinder 1, meanwhile, the slide block 5 drives the cut tumor tissue to move upwards, the rotating ring 14 is loosened, and the rotating ring 14 drives the arc-shaped plate 15 to rotate anticlockwise and reset under the action of the coil spring 16;

the tumor tissue in the needle cylinder 1 is cut off, the tumor tissue is continuously extruded into the needle cylinder 1 through the sampling port 2, at the moment, the push plate 8 can be pressed downwards, the push plate 8 drives the push rod 4 to move downwards and extrude the spring 9, the push rod 4 drives the cutting knife 6 to move downwards through the slider 5, meanwhile, the push plate 8 drives the limiting block 13 to move downwards through the elastic rod 12, and the limiting block 13 is inserted into the clamping groove 10, and because the lower end surface of the limiting block 13 is an inclined surface with a low inner part and a high outer part, the upper end of the outer side wall of the clamping groove 10 drives the limiting block 13 to swing inwards;

when the lower end surface of the sliding block 5 is contacted with the tumor tissue in the needle cylinder 1, the sliding block 5 continuously moves downwards, and the lower end surface of the sliding block 5 is a conical surface with a small lower part and a large upper part, the tumor tissue in the needle cylinder 1 is extruded out from the sampling port 2 by the sliding block 5, when the cutting knife 6 is positioned below the sampling port 2, the upper end surface of the limiting block 13 is contacted with the upper side wall of the limiting groove 11, the device is restored to the initial state, and the tumor tissue is extruded into the needle cylinder 1 through the sampling port 2;

repeating the above operation, continuously cutting the tumor tissue in the needle cylinder 1, and after enough samples are cut, pulling out the needle cylinder 1 from the human body, wherein the samples are not lost in the process of pulling out the needle cylinder 1 because the cut samples are all positioned in the needle cylinder 1;

after the needle cylinder 1 is pulled out of a human body, the fixing block 7 is rotated clockwise, the fixing block 7 drives the fixing cylinder 3 to rotate clockwise, meanwhile, the fixing cylinder 3 drives the push rod 4 to move upwards through the push plate 8, and the push rod 4 drives the cutting knife 6 and the sample of the needle cylinder 1 to move upwards through the slide block 5, so that the sample is moved out of the needle cylinder 1.
