The puncture needle body 20 is fixed by the first fastening screw 11, and a fixing plate 12 is fixed to the top of the base plate 1 by bolts. A scale 13 and a protractor 14 are fixed to one side of the fixing plate 12 by bolts. The sliding block 6 is pulled to slide on the support rod 5, thereby driving the connecting frame 9 to move, and at the same time driving the infrared laser emitter 8 to move, so that the infrared ray moves along the scale 13, thereby adjusting the distance between the infrared laser emitter 8 and the base plate 1, that is, adjusting the puncture length of the puncture needle, the bottom end of the scale 13 contacts the top of the base plate 1, and the center point of the protractor 14 corresponds to the rotation center of the iron movable frame 4. Rotating the iron movable frame 4 causes the infrared ray emitted by the infrared laser emitter 8 to rotate along the protractor 14, thereby driving the puncture needle body 20 to rotate, and then adjusting the puncture angle of the puncture needle body 20.

[0033] The top ends of the two support rods 5 are welded with limit blocks 15, which prevent the sliding block 6 from slipping off. The top of the bottom plate 1 is embedded with an arc panel 16. One side of the iron movable frame 4 is fixed with a first magnet block 17 by bolts.

Then, fix the puncture needle body 20 by the first fastening screw 11, and then rotate the iron movable frame 4 to make the infrared light emitted by the infrared laser emitter 8 rotate along the protractor 14, thereby driving the puncture needle body 20 to rotate, and then adjust the puncture angle of the puncture needle body 20, and then fix it by the second fastening screw 18, and then press the connecting frame 9 downward to drive the puncture needle body 20 to move downward, and then pierce the puncture needle body 20 into the patient's body.

[0035] Example 2

[0036] Reference Figure 6-Figure 7, an ultrasonic guiding device for facilitating precise puncture, comprising a guide groove 24 provided on the top of a bottom plate 1, a slider 25 slidably connected in the guide groove 24, a pad 26 fixed at one end of the slider 25 by bolts, the pad 26 is designed to serve as a bottom support when the puncture needle body 20 is inserted into the mounting tube 10, the upper surface of the pad 26 is flush with the upper surface of the bottom plate 1, an iron plate 27 is embedded in the bottom inner wall of the guide groove 24, a second magnet block 28 is fixed to the other end of the slider 25 by bolts, the second magnet block 28 is attracted to the iron plate 27, a handle 29 is fixed to the top of the slider 25 by bolts, after the puncture needle body 20 is fixed, the operator holds the handle 29 to slide the slider 25 to drive the pad 26 to slide in the guide groove 24, so that the puncture needle body 20 is separated from the pad 26, and a limiting strip 30 is fixed to the top of the bottom plate 1 by bolts.

[0037] Working principle of this embodiment: When in use, the pad 26 is designed to serve as a bottom support when the puncture needle body 20 is inserted into the mounting tube 10.
