[0024] Embodiment 1:

[0025] like Figure 1-3 shows a bonding tool for the inner catheter of a rotary biopsy needle, comprising a base plate 1 and a pad 2, the pad 2 being fixed on the top of the base plate 1, with a positioning plate 21 and a fixing plate 24 provided at both ends of the pad 2 respectively, the positioning plate 21 and the fixing plate 24 positioning the inner knife tube 8, a positioning block is provided in the middle of the pad 2, the positioning block is provided with a positioning groove, a power unit is provided under the pad 2, the power unit is used for driving the inner knife sleeve 9 to move to the positioning groove; wherein the inner knife tube 8 between the limit block 3 and the top block 4 is the glue dispensing position.

[0026] The power unit includes a cylinder 5 and a push block 6. The cylinder 5 is fixed under the pad 2. The cylinder 5 drives the push block 6 to move. The push block 6 passes through the pad 2 through the through groove 26. The through groove 26 corresponds to the positioning groove. The top of the push block 6 abuts against the end of the inner tool sleeve 9. A groove is set on the top of the push block 6, and the groove wall is in contact with the inner tool tube 8, thereby limiting the position of the inner tool tube 8 and pushing the inner tool sleeve 9.

[0027] A guide plate 23 is also provided on the backing plate 2 , and the guide plate 23 supports the inner knife sleeve 9 .

[0028] A top block 4 is provided in the middle of the pad 2, and the top of the top block 4 supports the inner knife tube 8, and the top block 4 is used to limit the inner knife sleeve 9; an adjustment groove and a locking bolt are provided on the positioning block, and the locking bolt passes through the adjustment groove and cooperates with the thread of the pad 2, and the locking bolt fixes the positioning block to the pad 2, and the adjustment groove is strip-shaped; the position of the positioning block is adjustable to facilitate the positioning adaptation of the inner knife sleeves 9 of different lengths, and the setting of the top block 4 assists in limiting the positioning position of the inner knife sleeve 9.

[0029] A fixing groove 27 is provided on the fixing plate 24, and a positioning piece 7 is provided at the center of the fixing groove 27. The positioning piece 7 is clamped and positioned with the cutter head of the inner knife tube 8. The cutter head of the inner knife tube 8 is the blade part. Directly positioning it with a plate will easily damage the cutter head and the positioning accuracy is poor. Therefore, the fixing groove 27 limits the cutter head to prevent it from moving left and right. The positioning piece 7 cooperates with the positioning plate 21 to limit the two ends of the inner knife tube 8 to prevent the inner knife tube 8 from moving forward and backward.

[0030] A limiting plate 22 is provided between the top block 4 and the positioning plate 21 . A limiting groove 25 is provided on the limiting plate 22 . The limiting groove 25 is used to position the inner knife tube 8 .
