[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a biopsy needle with an auxiliary operation component, including an outer set 1, the outer set 1 has a sampling needle structure 5 built in, the sampling needle structure 5 includes a puncture needle 51, the puncture needle 51 is built in the outer set 1, the outer set 1 and the puncture needle 51 are existing puncture sampling technologies, and the operation process is as follows: the outer set 1 cooperates with the tip of the puncture needle 51 to smoothly penetrate the patient's skin tissue, and at the sampling position, the puncture needle 51 is pushed out through the circular block 53, so that the sampling port above the puncture needle 51 can smoothly perform sampling operations on the tissue;

[0021] The puncture needle 51 slides in the middle of the connecting plate 3, and a circular block 53 is fixedly connected to the right end of the puncture needle 51. A first spring 52 is fixedly connected between the circular block 53 and the connecting plate 3. The elastic force of the first spring 52 can control the circular block 53 to reset to the right, so that the puncture needle 51 is retracted to the right into the outer sleeve 1, and the sampling port is built into the outer sleeve 1, avoiding the problem of contamination of the sampled tissue inside the sampling port;

[0022] The circular block 53 is located between the two ferrules 7, and the sampling needle penetrates and slides in the middle of the connecting plate 3, and the connecting plate 3 is fixedly connected to the right end of the outer set 1. Two openings 2 are provided on the upper and lower sides of one side of the connecting plate 3, and each opening 2 is provided with an elastic structure 6, and the elastic structure 6 includes a connecting block 63, and the connecting block 63 is fixedly connected to the bracelet 4. The connecting block 63 plays the role of connecting the bracelet 4 and the movable block 62, so that the movement of the bracelet 4 can control the movable block 62 to move;

[0023] A movable block 62 is fixedly connected to one side of the connecting block 63, and the inner cavity of the movable block 62 slides on the guide rod 61, and the guide rod 61 is fixedly connected to the upper and lower walls of the opening 2. The guide rod 61 can guide the movable block 62, so that the movable block 62 can slide smoothly, and avoid the problem that the wristband 4 and the connecting plate 3 are separated and affect the puncture operation;

[0024] A second spring 64 is fixedly connected to one side of the movable block 62, and the second spring 64 is arranged side by side with the guide rod 61, and an arc block 65 is fixedly connected to one end of the second spring 64, and the arc block 65 is fixedly connected to one side of the connecting plate 3. The elastic force of the second spring 64 can control the movable block 62 to reset, so that the connecting block 63 drives the bracelet 4 to reset, and then the ferrule 7 can be driven to separate from the circular block 53, which facilitates the operation of the circular block 53;

[0027] When sampling, first squeeze and tighten the bracelet 4, so that the bracelet 4 drives the two connecting blocks 63 and the movable block 62 to move, so that the movable block 62 drives the second spring 64 to deform, and the ferrule 7 is engaged with the circular block 53. At this time, the puncture needle 51 can be intermittently penetrated into the patient's skin tissue. At the sampling position, the bracelet 4 is released, so that the elastic force of the second spring 64 drives the connecting block 63 to reset, so that the bracelet 4 is reset and drives the ferrule 7 to separate from the circular block 53. At this time, the circular block 53 can be pushed to squeeze the first spring 52 to deform, so that the puncture needle 51 continues to penetrate into the sampling area, and the sampling port leaks out to sample the tissue. Then release the circular block 53, and the elastic force of the first spring 52 drives the puncture needle 51 to be retracted into the outer set 1, so that the sampling port is located in the outer set 1. At this time, tighten the bracelet 4 again to engage the ferrule 7 with the circular block 53, and then pull out the puncture needle 51.
