[0027] Specifically, before performing a puncture on a patient, the fixing frame 1 is set up on the patient's bed, and the fixing frame 1 is fixed to the bed using the clamping frame 2 and the fastening bolt 1 3 so that the fixing frame 1 is located above the patient's chest cavity. The fastening bolt 3 515 is loosened, and the adjustment frame 509 is rotated so that the adjustment frame 509 drives the threaded rod 2 511 to move closer to the threaded rod 1 510, and the sliding rod 2 516 is lifted to move the rotating platform 521 to a position above the patient's chest cavity and relatively close to the patient's chest cavity. The fastening bolt 3 515 is tightened, and the fastening bolt 4 518 and the fastening bolt 2 503 are loosened so that the rotating platform 521 can be moved laterally to the position close to the patient's heart puncture. To locate the puncture point, tighten the fastening bolt 4 518 and the fastening bolt 2 503, rotate the adjusting frame 509 again and overcome the elastic force of the elastic spring 508 to press the locking piece 507, so that the locking piece 507 is released from the clamping connection with the rack 1 506, and the movable piece 2 505 slides on the upper cross bar 504, so that the whole formed by the threaded rod 1 510, the adjusting frame 509 and the threaded rod 2 511 pushes and pulls the rotating table 521, and with the help of the sleeve 527 on the telescopic rod 526, the rotating table 521 can be rotated on the movable sleeve 520, so that the directional cylinder 4 can be aligned with the puncture point at a certain angle.

[0028] In a specific application scenario, the positioning and angle-fixing module 5 is mainly suitable for the positioning and angle-fixing link in the positioning and angle-fixing process, that is, the positioning and angle-fixing module 5 uses the movable sleeve 520, the rotating table 521 and the directional cylinder 4 to help doctors accurately locate the puncture position and angle when performing cardiology puncture treatment on patients, thereby effectively reducing the impact of puncture deviation or failure on the treatment effect, reducing harm to patients, and improving the safety of treatment.

[0029] Reference Figure 6 and Figure 7In a preferred embodiment, a cardiology puncture device includes a cardiology puncture assembly as described above, and further includes a syringe 6, one end of the syringe 6 is plugged with a puncture needle 7, the outside of the syringe 6 is plugged with the inner wall of the directional cylinder 4, the outside of the rotating platform 521 is connected to a mounting seat 9 by bolts, a circular hole is opened on the mounting seat 9, an adjusting screw 8 is connected to the circular hole by rotating on a bearing, and a gear ring 11 is connected to the outside of the adjusting screw 8 by bolts; the gear ring 11 is rotatably connected to the side opposite to the mounting seat 9 by a bearing, and a locking ring 10 is provided on the outside of the gear ring 11, and the inner wall of the locking ring 10 is connected by bolts. There is a rack 2 12, and the rack 2 12 is clamped with the gear ring 11; the outside of the locking ring 10 is slidably connected to a guide buckle 13, and the guide buckle 13 is connected to the side opposite to the mounting seat 9 by bolts, and the side of the guide buckle 13 away from the gear ring 11 is connected to a spring 2 14 by bolts, and the end of the spring 2 14 away from the guide buckle 13 is connected to the inner wall of the locking ring 10 by bolts; the outside of the adjusting screw 8 is rotatably connected to the transmission ring 15 through an external thread, and the outside of the transmission ring 15 is connected to the outside of the slider 525 close to the side of the transmission ring 15 by bolts, and the transmission ring 15 is located on the side of the mounting seat 9 away from the locking ring 10.

[0030] Specifically, after the syringe 6 is inserted into the directional cylinder 4 and fixed, the puncture needle 7 is installed on the syringe 6, and the locking ring 10 is pushed up by overcoming the elastic force of the spring 2 14. Under the guidance of the guide buckle 13, the locking ring 10 moves up, so that the rack 2 12 releases the lock on the gear ring 11, and the adjusting screw 8 is rotated. The rotating adjusting screw 8 will push the transmission ring 15 connected to the slider 525 to move, so that the slide 523 drives the syringe 6 in the directional cylinder 4 to move toward the patient's puncture position and finally completes the patient's cardiology puncture as the adjusting screw 8 continues to rotate. After the puncture reaches the position, the locking ring 10 is released. Under the elastic force of the spring 2 14, the locking ring 10 returns to its original position, so that the rack 2 12 locks the gear ring 11, and the adjusting screw 8 no longer rotates.

[0031] In a specific application scenario, the device uses the adjusting screw 8, the locking ring 10, the rack 2 12 and the gear ring 11 to enable the device to stably puncture the puncture needle 7 into the patient's chest cavity during the puncture operation, and when the puncture is in place, ensure that the position of the puncture needle 7 will not shift with the movement of the doctor or the patient, thereby avoiding the needle tip of the puncture needle 7 being pulled out or shifting in the patient's body, causing puncture failure or scratching of internal organs, thereby reducing the risk.

[0032] Working principle: Before performing puncture on the patient, the fixing frame 1 is set up on the patient's bed, and the fixing frame 1 is fixed to the bed using the clamping frame 2 and the fastening bolt 1 3 so that the fixing frame 1 is located above the patient's chest cavity. The fastening bolt 3 515 is loosened, and the adjustment frame 509 is rotated so that the adjustment frame 509 drives the threaded rod 2 511 closer to the threaded rod 1 510, and the sliding rod 2 516 is lifted to move the rotating platform 521 to a position above and closer to the patient's chest cavity. The fastening bolt 3 515 is tightened. , loosen the fastening bolt 4 518 and the fastening bolt 2 503, so that the rotating platform 521 can be moved horizontally to a position close to the patient's cardiac puncture point, tighten the fastening bolt 4 518 and the fastening bolt 2 503, rotate the adjustment frame 509 again and overcome the elastic force of the elastic spring 508 to press the locking piece 507, so that the locking piece 507 is released from the clamping of the rack 1 506, and the movable piece 2 505 slides on the upper cross bar 504, thereby making the threaded rod 1 510, the adjustment frame 509 and the threaded rod 2 51 1 pushes and pulls the rotating platform 521, and the sleeve 527 is extended or shortened on the telescopic rod 526, so that the rotating platform 521 can rotate on the movable sleeve 520, so that the directional cylinder 4 can be aligned with the puncture point at a certain angle. After the syringe 6 is inserted into the directional cylinder 4 and fixed, the puncture needle 7 is installed on the syringe 6, and the elastic force of the spring 14 is overcome to push the locking ring 10 upward. Under the guidance of the guide buckle 13, the locking ring 10 moves upward, thereby releasing the rack 12. In addition to locking the gear ring 11, the adjusting screw 8 is rotated. The rotating adjusting screw 8 will push the transmission ring 15 connected to the slider 525 to move, so that the slide 523 drives the syringe 6 in the directional cylinder 4 to move toward the patient's puncture position and finally completes the patient's cardiology puncture as the adjusting screw 8 continues to rotate. After the puncture reaches the position, the locking ring 10 is released. Under the elastic force of the spring 2 14, the locking ring 10 returns to its original position, so that the rack 2 12 locks the gear ring 11, and the adjusting screw 8 no longer rotates.
