Detailed implementation manner

[0026] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. Obviously, what is described is only a part of the present invention, not all of it. Based on the present invention, all other innovations obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0027] As Figures 1-12 shown, the present invention provides an ultrasonic intelligent guiding and assisting puncture device, including an ultrasonic probe 1, an adsorption rack 2 is assembled on the outside of the ultrasonic probe 1, a traction mechanism 3 is arranged around the adsorption rack 2, an angle mechanism 4 is arranged on one outer side of the adsorption rack 2, and a puncture needle 5 is assembled on the angle mechanism 4.

[0028] This invention uses the ultrasonic probe 1 to assist the puncture needle 5 to puncture the patient's skin surface, and improves the puncture accuracy of the puncture needle 5 through the adsorption rack 2, the traction mechanism 3 and the angle mechanism 4, reducing the pain impact on the patient caused by secondary puncture.

[0029] Before using this puncture device, apply ultrasonic coupling agent to the area of the patient that needs to be punctured for examination. The ultrasonic coupling agent is an aqueous preparation, which is relatively safe and will not cause irritation to the human skin or mucous membrane. Patients can rest assured. It is a substance that must be used in ultrasonic scanning. Generally, it will be applied to the skin or mucous membrane, which can fill the tiny gaps between the probe and the skin and prevent the tiny amount of air in the gaps from affecting the penetration of ultrasonic waves.

[0030] After applying the ultrasonic coupling agent, the adsorption rack 2 on one side of the adsorption cavity 202 in the device can be placed in close contact with the patient's skin surface. The specific placement process is as follows: When holding the adsorption rack 2 and placing it on the skin surface, due to the squeezing force on the skin surface, the second spring 310 between the lifting block 309 and the upper top plate 313 is compressed, driving the lifting block 309 and the connecting rope 308 near one end of the lifting block 309 to move upward towards the upper top plate 313. Among them, the sliding rod mechanism 314 between the lifting block 309 and the upper top plate 313 restricts the circumferential rotation of the lifting block 309. One end of the connecting rope 308 in the device is fixedly connected to the driving rack 306, and the first spring 307 fixedly connected between the bottom of the driving rack 306 near one end of the connecting rope 308 and the outer top of the adsorption rack 2 makes the initially stretched first spring 307 gradually reduce its stretching, driving the driving rack 306 fixedly connected to one end of the connecting rope 308 to move along the sliding groove 201 towards the periphery of the adsorption rack 2. The cooperation between the sliding groove 201 and the sliding rail 312 prevents the driving rack 306 from deflecting and dislocating. The driving rack 306 moves along the sliding groove 201 towards the periphery of the adsorption rack 2, causing the driven gear 305 meshed with the upper part of the driving rack 306 to rotate, driving the first connecting shaft 304 fixedly connected to the central position of the driven gear 305 to rotate, and making the folding plates 303 fixedly connected to the circumferential surface of the four first connecting shafts 304 perform a rotational movement centered on the first connecting shaft 304. The end of the folding plate 303 near the clip 302 gradually moves away from the adsorption rack 2, driving the elastic scraping belt 301 clamped between the four clips 302 to move and expand towards the outer periphery of the adsorption rack 2. The elastic scraping belt 301 with elasticity and a width of about 1 cm can scrape the ultrasonic coupling agent on the patient's skin surface towards the outer periphery of the adsorption rack 2. After the elastic scraping belt 301 completely moves to the outer periphery of the adsorption rack 2, the outer bottom of the adsorption rack 2 gradually comes into contact with the patient's skin. When the outer bottom of the adsorption rack 2 is completely in contact with the patient's skin, the traction mechanism 3 stops operating internally. At this time, the micro vacuum pump 101 provided on one side of the ultrasonic probe 1 is started, and the air in the several adsorption cavities 202 separated by the inner wall of the adsorption rack 2 is extracted along the corrugated pipe 102, the air extraction pipe 103 and the ventilation pipe 203, so that the air in the several adsorption cavities 202 gradually decreases, forming a pressure difference between the inner wall of the adsorption rack 2 and the outside world, making the outer bottom of the adsorption rack 2 adsorb on the patient's skin surface, improving the stability of the device, facilitating the fixation of the inspection position of the ultrasonic probe 1 and the stable puncture of the puncture needle 5, facilitating the ultrasonic probe 1 to detect the lesion position, and improving the safety of use.

[0031] After the adsorption frame 2 is placed on the patient's skin surface in a fitting manner on one side of the adsorption cavity 202, puncture needs to be performed. The specific puncture process is as follows: Insert the puncture needle 5 into the sleeve provided at the top of the angle plate 402. The puncture needle 5 can move up and down along the inner wall direction of the sleeve. Then, calculate the puncture angle according to the lesion position. The limiting blocks 406 respectively fixed to the opposite outer sides of the adsorption frame 2 are respectively rotationally matched with the two rotating rods 405. By rotating the connecting plate 407 fixed to the circumferential surface of the rotating rod 405, drive the two second rotating plates 404 fixedly connected to the circumferential surface of the rotating rod 405 to perform a rotational movement centered on the rotating rod 405, drive the first rotating plates 403 respectively rotationally matched with one ends of the two second rotating plates 404 to rotate, and thus drive the angle plate 402 rotationally matched between the two first rotating plates 403 to perform a rotational movement centered on one end of the horizontal plate 401, realizing the angle adjustment of the puncture needle 5. After the angle adjustment of the puncture needle 5 is completed, fixedly connect the connecting plate 407 and the mounting ring 205 through bolts. The angle sensor provided on the connecting plate 407 can measure the rotation angle of the rotating rod 405 in real time, achieving that the angle adjustment direction of the puncture needle 5 is consistent with the moving direction of the ultrasonic probe 1, which is beneficial to accurately exploring with the ultrasonic probe 1 during the puncture process.

[0032] During the puncture process of the puncture needle 5, the ultrasonic probe 1 can move horizontally and even change the exploration angle of the ultrasonic probe 1. The ultrasonic probe 1 will be affected by the metal puncture needle 5, so changing the exploration angle of the ultrasonic probe 1 can reduce this influence. The limiting rods 104 provided on the opposite sides of the ultrasonic probe 1 can move horizontally along the two limiting grooves 204 opened on the adsorption frame. The sliding fit between the two horizontal frames 105 and the limiting rods 104 further improves the exploration stability of the ultrasonic probe 1.

[0033] The above-mentioned cooperation between the traction mechanism 3 and the adsorption frame 2 improves the stability of the device, and adjusts the angle between the puncture needle 5 and the adsorption frame 2 and the angle between the puncture needle 5 and the ultrasonic probe 1 through the traction mechanism 3.
