[0048] The installation and fixation of the positioning plate 705 is achieved by providing the mounting plate 719, the protrusion 721 is driven to move and reset by providing the reset spring 725, and the space for the column 726 to move and avoid is provided by providing the guide hole 722.
[0049] In this embodiment, a rotating disk 727 is rotatably connected to the inner wall of the positioning disk 705 , a protrusion 721 is fixedly connected to the surface of the rotating disk 727 , and one end of the return spring 725 is fixedly connected to the surface of the protrusion 721 .
[0050] The protrusion 721 is provided to facilitate an operator to push the protrusion 721 to drive the rotating disk 727 to rotate as a whole. The position of the arc hole 724 can be changed by providing the rotating disk 727 .
[0051] In this embodiment, an arc hole 724 is opened on the surface of the turntable 727, and a column 726 is installed on the inner wall of the arc hole 724. One end of the column 726 is fixedly connected to the roller frame 723. The column 726 is installed inside the guide hole 722, and a wire hole 728 is opened on the surface of the positioning plate 705.
[0052] The arc hole 724 is provided to affect the movement of the column 726, and the roller frame 723 is provided to position and clamp the medical catheter to be used later to prevent the catheter from bending, entanglement and failure to complete the diversion operation, and the wire hole 728 is provided to avoid the catheter.
[0053] The working principle of the present invention is: an intracardiac puncture positioning device, when the user uses it, after the patient lies on the external bed, the user rotates the positive and negative screw rods 706, so that a pair of clamping plates 708 are close to each other, the syringe 4 is clamped and kept stable, and then the operator rotates the first screw rod 701 to adjust the position of the height adjustment plate 2, and then rotates the second screw rod 702 to adjust the height of the sleeve 3, and then continues to slide the slide bar 6. After adjusting the position of the slide bar 6 in the sleeve 3, the height of the slide bar 6 is changed by rotating the threaded rod 703, the slide bar 6 is squeezed, the friction is increased, and the position of the slide bar 6 is fixed. At this time, the needle 5 is close to the skin position of the patient where the needle is needed. The operator then rotates the worm 714, which rotates in coordination with the turbine 718 to drive the adjustment platform 704 to slide on the surface of the fixed arc plate 712. In this process, the movement of the adjustment platform 704 drives the angle position of the pointer 710 to change through the L-shaped linkage block 715. When the adjustment platform 704 is perpendicular to the bed, the pointer 710 indicates the zero scale line position on the surface of the angle disk 711. As the overall angle of the adjustment platform 704 changes, the overall angle of the syringe 4 is driven to change, and at the same time, the angle of the pointer 710 changes, so as to understand the vertical angle of the overall rotation of the adjustment platform 704, so as to better perform the operation. To perform precise acupuncture, by setting the pointer 710, the specific angle of rotation is accurately observed. Since the needle 5 is close to the skin that needs to be acupunctured, after adjusting the angle of the syringe 4, the operator continues to rotate the first screw 701 to drive the height adjustment plate 2 and the syringe 4 to move as a whole, so that the needle 5 is inserted into the patient's pericardium. The operator operates the movable plug rod of the syringe 4 to collect the effusion. After manual extraction, the needle 5 is manually separated from the syringe 4. At this time, one end of the needle 5 is connected to the external catheter located in the wire hole 728 to perform the diversion operation. When the external catheter is inserted into the wire hole 728, the operator can push the bump 721, drives the turntable 727 to rotate as a whole. The rotation of the turntable 727 changes the position of the arc hole 724. The arc hole 724 affects the movement of the column 726 and cooperates with the guide hole 722 to drive multiple roller frames 723 to move away from each other. After loosening the protrusion 721, under the action of the reset spring 725, the multiple roller frames 723 are driven to move closer to each other, and the external medical catheter located in the wire hole 728 is positioned and clamped. The advantage of this is that it prevents the catheter from bending, entanglement and bending and making it impossible to complete the diversion operation. With the above structure, the needle is positioned accurately, the auxiliary equipment guides the needle, the angle will not deviate, and the safety of the operation is improved.
[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
