[0023] Please refer to Figures 1-4An embodiment of the present invention is as follows: an artificial intelligence-assisted device for arteriovenous fistula puncture of dialysis patients with vascular imaging display, comprising a base 1, a support column 2 and a vascular imaging display 4, wherein the upper end of the base 1 is fixedly connected to the support column 2, the upper end of the support column 2 is movably connected to a movable rod 3, the end of the movable rod 3 is installed with the vascular imaging display 4, an adjustment mechanism 5 is arranged on the left side of the base 1, and a puncture needle 6 is arranged on the left end of the adjustment mechanism 5,

[0024] The adjusting mechanism 5 includes a universal joint 501, a connecting member 502, a positioning rod 503, a first support frame 504, a second support frame 505, a first guide plate 506, a second guide plate 507, a slide groove 508, a first motor 509 and a second motor 510. The universal joint 501 is arranged on the left side of the support column 2, the connecting member 502 is arranged on the left end of the universal joint 501, the positioning rod 503 is arranged on the left end of the connecting member 502, the first support frame 504 is connected to the left side of the support column 2, the second support frame 505 is arranged at the center position of the first support frame 504, the first guide plate 506 is arranged on the inner side of the first support frame 504, the second guide plate 507 is arranged on the inner side of the second support frame 505, the slide groove 508 is opened on the inner sides of the first guide plate 506 and the second guide plate 507, the first motor 509 is arranged on the upper end of the second support frame 505, and the second motor 510 is arranged on the rear end of the second support frame 505;

[0025] The device solves the problem that nurses currently rely on hand feeling to perform punctures, and that multiple punctures are likely to cause secondary injuries to patients with poor vascular conditions, by providing the adjustment mechanism 5 and the needle insertion assembly 7.

[0026] Furthermore, the connector 502 is provided with a needle insertion assembly 7, which includes a small electric push rod 71 and a guide groove 72. The small electric push rod 71 is fixedly installed at the center of the connector 502, and the guide groove 72 is provided in the positioning rod 503. The left end of the guide groove 72 is inserted with a puncture needle 6, and the output end of the small electric push rod 71 is in contact with the inner end of the puncture needle 6. Figure 3 As shown, this structure is used to start the small electric push rod 71 so that the output end pushes the puncture needle 6 to move along the guide groove 72. The advancement of the small electric push rod 71 can control the insertion depth of the puncture needle 6 to avoid exceeding the puncture range.

[0027] Further, the first support frame 504 and the second support frame 505 are fixedly installed on the left side of the support column 2 with the universal joint 501 as the center. The first support frame 504 and the second support frame 505 are C-shaped. The right end of the universal joint 501 is movably connected to the support column 2. The other end of the universal joint 501 is fixedly connected with a connecting piece 502. The right end of the positioning rod 503 is fixedly connected with the connecting piece 502. The two ends of the first guide plate 506 are respectively rotatably connected to the upper and lower ends of the first support frame 504. The two ends of the second guide plate 507 are respectively rotatably connected to the front and rear ends of the second support frame 505. The first guide plate 506 and the second guide plate 507 are semi-circular. The diameter of the sliding groove 508 is adapted to the positioning rod 503. The sliding groove 508 sequentially passes through the first guide plate 506 and the second guide plate 507. As Figure 2 shown, this structure is used to project the positions of arterial and venous blood vessels through the vascular imaging display 4. According to the blood vessel positions, the first motor 509 is started. Driven by the first motor 509, the first guide plate 506 rotates on the X-axis. At the same time, the second motor 510 is started. Driven by the second motor 510, the second guide plate 507 rotates on the Y-axis. Rotationally connected to the support column 2 through the universal joint 501, the positioning rod 503 in the sliding groove 508 reaches the specified position under the cooperation of the first motor 509 and the second motor 510, facilitating puncture at any angle.

[0028] Further, an angle sensor 8 is fixedly installed at the central position of the universal joint 501. The output end of the angle sensor 8 faces the central position of the connecting piece 502. As Figure 3 shown, this structure is used to synchronize the rotation angle of the universal joint 501 through the angle sensor 8, calibrate and indicate the angle of the universal joint 501, avoid causing errors, and improve the accuracy of the device.

[0029] Further, two groups of indicator lights 9 are fixedly installed on the front surface of the support column 2. The two groups of indicator lights 9 are respectively electrically connected to the first motor 509 and the second motor 510. As Figure 4 shown, this structure is used through the two groups of indicator lights 9. When the first motor 509 drives the positioning rod 503 to reach the specified X-axis, one group of indicator lights 9 lights up green, indicating that the specified position has been reached. When the specified position has not been reached or the position deviates from the specified position, the indicator light 9 connected to the X-axis lights up red. When the second motor 510 drives the positioning rod 503 to reach the specified Y-axis, the corresponding indicator light 9 lights up green, and when the specified position has not been reached, it lights up red in the same way.

[0030] Further, a voice module 10 is installed on the surface of the support column 2 above the indicator lights 9. The voice module 10 is electrically connected to the angle sensor 8, and the voice module 10 is electrically connected to the small electric push rod 71. As Figure 4As shown, this structure is used to announce the angle of the positioning rod 503 through the voice module 10, and announce the depth of the puncture needle 6 during needle insertion.

[0031] Furthermore, a laser emitter 11 is installed at the left end of the positioning rod 503. The output end of the laser emitter 11 is located at the inner bottom side of the positioning rod 503. The color of the light irradiated by the laser emitter 11 is different from and darker than the color projected by the blood vessel imaging display 4, which is convenient for medical staff to distinguish and observe. As Figure 4 shown, this structure is used to directly see the puncture position of the positioning rod 503 through the laser emitter 11 and disinfect and clean this position.

[0032] Working principle: As Figure 1 and Figure 2 shown, place the patient's limb on the surface of the base 1, adjust the movable rod 3 correspondingly according to the patient's body type to make the projection of the blood vessel imaging display 4 clear. The irradiated image of the blood vessel imaging display 4 is projected on the local area of the patient's internal fistula. Then, according to the blood vessel positions of the patient's artery and vein, start the first motor 509. Driven by the first motor 509, the first guide plate 506 rotates on the X-axis. At the same time, start the second motor 510. Driven by the second motor 510, the second guide plate 507 rotates on the Y-axis. The positioning rod 503 in the chute 508 is rotationally connected to the support column 2 through the universal joint 501. Under the cooperation of the first motor 509 and the second motor 510, as Figure 3 and Figure 4 shown, through the irradiation of the laser emitter 11, the puncture position of the positioning rod 503 can be directly seen, and this position can be disinfected and cleaned. At the same time, the angle sensor 8 can synchronize the rotation angle of the universal joint 501, proofread and indicate the angle of the universal joint 501 to avoid errors. When the first motor 509 drives the positioning rod 503 to reach the specified X-axis, a group of indicator lights 9 turn on the green light, indicating that the specified position has been reached. When it does not reach the specified position or deviates from the specified position, the indicator light 9 connected to the X-axis turns on the red light. When the second motor 510 drives the positioning rod 503 to reach the specified Y-axis, the corresponding indicator light 9 turns on the green light. Similarly, when it does not reach the specified position, the red light turns on. When the specified position is reached, start the small electric push rod 71 to make the output end push the puncture needle 6 to move along the guide groove 72. The advancement of the small electric push rod 71 can control the needle insertion depth of the puncture needle 6 to avoid exceeding the puncture range. The voice module 10 announces the angle of the positioning rod 503, and announces the depth of the puncture needle 6 during needle insertion. The above is the entire working principle of the present invention.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
