The angle adjustment mechanism can adjust and position the angle of the movable rod 9. The length adjustment mechanism can adjust the length of the movable rod 9 from the fixed rod 8 and position;

The bottom of the movable rod 9 is fixed with a circular adjustment frame 10, and the left and right sides of the circular adjustment frame 10 are symmetrically provided with a first chute 11, and each of the first chute 11 is slidably installed. There are first sliders 12, and two first sliders 12 make circular movements around the central axis of the circular adjustment frame 10 in the corresponding first chute 11, and the inside of each first slider 12 is The first connecting rod 13 is installed in rotation, and the middle part of the circular adjustment frame 10 is provided with a clamping block 14, and the other end of each of the first connecting rods 13 is fixedly connected with the clamping block 14. Under the cooperative action of a slider 12 and two first connecting rods 13, the clamping block 14 can follow the two first sliders 12 to rotate around the central axis of the circular adjustment frame 10 in the circular adjustment frame 10, and can Following the rotation of the two first connecting rods 13 around the central axis of the first connecting rods 13, the front and rear sides of the circular adjustment frame 10 are symmetrically rotated and installed with engaging pieces 15, and the two engaging pieces 15 are directed in opposite directions. The two connecting pieces 15 are rotatably equipped with a second connecting rod 66, and the other ends of the two second connecting rods 66 are fixedly connected to the clamping block 14. When the connecting piece 15 at the front rotates, the The cooperation of the two connecting pieces 15 and the two second connecting rods 66 can make the clamping block 14 swing in the circular adjustment frame 10, and the front end of the connecting piece 15 at the front is fixedly equipped with a knob 16, and the clamping piece The inside of the holding block 14 is detachably equipped with a puncture needle 17, and the inside of the puncture needle 17 is slidably installed with a needle core 18. Under the cooperation of the connecting rod 13 and the second connecting rod 66, the puncture needle 17 follows the clamping block 14 to make an 8-shaped movement in the curved surface, so that the puncture needle 17 can face multiple directions;

When performing a puncture, the medical staff first raises the arc-shaped support 5 so that the arc-shaped support 5 is in an open state. The patient lies on the hospital bed with his head resting on the headrest 2 and the neck is located on the base plate 1, and the arc-shaped support 5 is rotated. , so that the right end of the arc-shaped support 5 is plugged into the slot 6, and the arc-shaped support 5 is in a closed state at this time, select a suitable puncture needle 17 and install it in the clamping block 14, and drive the arc-shaped support 5 to move through the power assembly , preliminarily adjust the position of the puncture needle 17, so that the puncture needle 17 and the puncture site are roughly in the same vertical plane;

When the puncture site is on the side of the neck, the angle of the fixed rod 8 is adjusted by the angle adjustment mechanism, thereby adjusting the angle of the circular adjustment frame 10, further adjusting the position of the puncture needle 17, so that the puncture needle 17 is further aligned The puncture site: adjust the length of the movable rod 9 extending from the fixed rod 8 through the length adjustment mechanism, so that the puncture needle 17 slowly approaches the puncture site, and stop adjusting the length adjustment mechanism;
