By adjusting the connection angle between the strip plate Ⅰ1 and the strip plate Ⅱ2, the suction cup 5 at the bottom of the strip plate Ⅰ1 and the strip plate Ⅱ2 can be directly adsorbed at the puncture position, and the positioning member 9 of the limited puncture needle can be flexibly adjusted by the driving member 7 and the adjusting member 8, so that the puncture needle can perform puncture at different angles under the support and limit conditions.

[0022] like Figure 3 and Figure 4 As shown, the driving member 7 includes a screw rod 701 and a motor 702. The screw rod 701 is symmetrically rotatably connected to the inner groove of the mounting plate 601. The screw rod 701 is threadedly connected to the sliding block 602 on the same side. The motor 702 is installed on one side of the groove of the mounting plate 601, and the output shaft of the motor 702 is connected to the screw rod 701.

[0023] like Figure 1 , Figure 3 and Figure 4As shown, the adjusting member 8 includes: a gear 801, which is installed on the rotating shaft of the circular mounting frame 603; a rack 802, which is slidably installed on the inner side of the mounting plate 601, and the rack 802 can mesh with the gear 801; an electric push rod 803, which is fixedly installed on the inner side of the mounting plate 601, and the push rod of the electric push rod 803 is connected to the rack 802; a positioning card plate 804, the top surfaces of the strip plates Ⅰ1 and Ⅱ2 are close to the outer side of the mounting plate 601 and are provided with sliding grooves, and the positioning card plate 804 slides through the sliding grooves and is symmetrically slidably connected to the strip plates Ⅰ1 and Ⅱ2 The top surface of the positioning card plate 804 is evenly provided with a row of fine card holes for positioning; the connecting rod 805 is fixedly connected to the positioning card plate 804, and the limiting block is fixedly connected to the connecting rod 805; the driving plate 806 is fixedly connected to the end of the rack 802 away from the gear 801, and the driving plate 806 is provided with a guide groove, and the connecting rod 805 is slidably connected in the guide groove of the driving plate 806. The limiting block on the connecting rod 805 is limited up and down on the driving plate 806. When the driving plate 806 slides up and down following the rack 802, the driving plate 806 will pass through the limiting block The connecting rod 805 and the positioning card plate 804 are synchronously driven to move synchronously, and the connecting rod 805 can slide left and right relative to the driving plate 806; the connecting block 807 is fixedly connected to the outer side of the sliding block 602, and the lower part of the connecting block 807 is fixedly connected with a card pin adapted to the card hole on the positioning card plate 804. When the rack 802 is driven downward by the electric push rod 803 to disengage from the meshing with the gear 801, the rack 802 synchronously drives the connecting rod 805 and the positioning card plate 804 to move downward through the driving plate 806, so that the card hole on the positioning card plate 804 no longer blocks the connecting block 807 The card pin on the drive member 7 can drive the sliding block 602 and the circular mounting frame 603 to slide and adjust the puncture position. When adjusted to the required position, the electric push rod 803 is controlled to drive the rack 802 to engage the gear 801, and the card hole of the positioning card plate 804 is inserted into the card pin of the connecting block 807. When the rack 802 engages the gear 801, the mounting plate 601 slides, so that the circular mounting frame 603 can accurately rotate at the positioning point to adjust the puncture support angle. At the same time, because the rack 802 engages the gear 801, the adjusted puncture support angle cannot be changed at will.

[0024] like Figure 1 , Figure 5 , Figure 6 and Figure 8As shown, the positioning member 9 includes: an arc slider 901, which is slidably installed in the inner ring of the ring mounting frame 603; an arc silicone plate 902, which is installed inside the arc slider 901, and a needle hole adapted to the size of the puncture needle is opened at the center of the arc silicone plate 902; a damping telescopic rod 903, which is arranged between the ring mounting frame 603 and the arc slider 901, and the arc slider 901 can provide a certain resistance when sliding in the ring mounting frame 603, thereby improving the accuracy of puncture by slowing down the speed of the puncture needle; the arc slider 901 01 and the arc silicone plate 902 are both arcs with notches, and the arc silicone plate 902 is detachably installed in the arc slider 901, and the arc silicone plate 902 can be easily replaced on the arc slider 901; a guide rod 12 for guiding is arranged between the circular ring mounting frame 603 and the arc slider 901, and the guide rod 12 passes through the arc slider 901, and a spring II 13 is arranged on the guide rod 12 between the circular ring mounting frame 603 and the arc slider 901, and the spring II 13 can provide elastic force for the arc slider 901 to reset after being compressed.

[0025] like Figure 1 and Figure 5As shown, a scale plate 14 for assisting precise adjustment is provided on the outer side of the mounting plate 601, and fine scales corresponding to the holes on the positioning card plate 804 are provided on the scale plate 14. When the motor 702 drives the sliding block 602 to slide on the mounting plate 601 through the screw rod 701, the connecting block 807 slides synchronously with the sliding block 602 and indicates on the scale plate 14, thereby assisting medical personnel to accurately adjust the required position for puncture. First, when using the device for puncture positioning, the doctor can first adjust the angles of the strip plate I1 and the strip plate II2 according to the patient's specific situation, so that the suction cup 5 at the bottom of the device is in close contact with the skin surface of the predetermined puncture site to ensure the stability of the positioning device, and first start the electric push rod 803, the push rod of the electric push rod 803 contracts and pulls the rack 802 downward, so that the rack 802 is disengaged from the meshing with the corresponding gear 801, and the downward-moving rack 802 will synchronously drive the driving plate 806 to move downward, and at this time, the driving plate 806 will drive the positioning card plate 804 to move downward in the slide groove of the strip plate I1 or the strip plate II2 through the connecting rod 805, and the positioning card plate 804 on the downward-moving The card hole will be disengaged from the limit of the card pin on the connecting block 807, and then by starting the motor 702, the output shaft of the motor 702 will synchronously drive the screw rod 701 to rotate, and the rotating screw rod 701 drives the sliding block 602 to translate on the inner side of the mounting plate 601 through the thread, thereby driving the annular mounting frame 603 to move with the sliding block 602. In this process, since the gear 801 is not engaged with the rack 802, the sliding block 602 can drive the annular mounting frame 603 and the connecting block 807 to move on the mounting plate 601. At this time, the doctor can accurately control the adjustment of the annular mounting frame 603 by observing the position change between the scale plate 14 and the connecting block 807. The distance and position of the joints are adjusted. When the annular mounting frame 603 is accurately adjusted to the required puncture position, the motor 702 is turned off and the push rod is enabled again. At this time, the electric push rod 803 pushes the rack 802 upward. When the rack 802 meshes with the gear 801, the rack 802 will also drive the connecting rod 805 and the positioning card plate 804 to reset and move upward through the driving plate 806, and make the card hole on the positioning card plate 804 card into the card pin on the well-positioned connecting block 807, so that the annular mounting frame 603 is firmly positioned at the position where puncture is required. At this time, the motor 702 is enabled to drive the screw rod 701 again, and the screw rod 701 drives the sliding block 602 and the annular mounting frame 603 to move, so that the gear The wheel 801 meshes with the rack 802, and the annular mounting frame 603 is positioned so that the mounting plate 601 will slide on the corresponding strip plate Ⅰ1 or strip plate Ⅱ2, so that the annular mounting frame 603 can rotate at the positioning point to adjust the puncture angle. After the puncture angle is adjusted, the motor 702 is turned off. Since the gear 801 is always meshed with the rack 802, the annular mounting frame 603 can stably maintain the adjusted support angle. Therefore, according to the actual puncture needs, by separately controlling the motor 702 and the electric push rod 803, the doctor can flexibly and accurately adjust the position and angle of the puncture needle according to the actual needs, ensuring that the puncture needle can accurately reach the target position.When the position and angle of the circular mounting frame 603 are adjusted, the puncture needle can be inserted through the pinhole in the center of the arc silicone plate 902. At this time, the arc silicone plate 902 will hold and limit the puncture needle. At the same time, driven by the friction of the puncture needle, the arc silicone plate 902 and the arc slider 901 will slide inside the circular mounting frame 603. The sliding arc slider 901 will be guided by the guide rod 12 and pressed on the damping telescopic rod 903 and the spring II 13 at the same time. The damping telescopic rod 903 provides appropriate resistance and cooperates with the elastic force provided by the spring II 13 for buffering, which helps to control the insertion speed of the puncture needle, thereby helping to improve the accuracy of puncture.

[0026] Embodiment 2: Based on embodiment 1, Figure 1 and Figure 7 As shown, a guide assembly 10 is provided on the circular mounting frame 603, and the guide assembly 10 includes: a guide frame 101, which is symmetrically fixed on the opening side of the circular mounting frame 603, and the guide frame 101 is symmetrically provided with sliding openings; a guide plate 103, which is symmetrically slidably connected to the sliding opening between the two guide frames 101 through a connecting frame 102, and the guide plate 103 is semicircular, and the symmetrical guide plates 103 can form a complete circular guide bucket; a spring I 104, which is arranged between the ends of the two connecting frames 102 away from the guide plate 103.

[0027] like Figure 1 , Figure 5 and Figure 6 As shown, a limiting member 11 is also provided on the circular mounting frame 603, and the limiting member 11 includes: a pressing plate 111, which is slidably installed on the top of the circular mounting frame 603 through a sliding rod, and the pressing plate 111 is used to cooperate with the arc silicone plate 902 to clamp and limit the puncture sheath; a threaded rod 112, which is fixed to the pressing plate 111 at the rod end after the sliding rod passes through the circular mounting frame 603; an adjusting thread block 113, which is rotatably installed on the top of the circular mounting frame 603, and the adjusting thread block 113 and the threaded rod 112 are threadedly adapted. By twisting the adjusting thread block 113, the threaded rod 112 drives the pressing plate 111 to slide down in the circular mounting frame 603 and be limited on the puncture sheath.

[0028] After the puncture needle successfully penetrates the artery, the doctor inserts a guide wire through the needle hole of the puncture needle. After the guide wire also enters the blood vessel, the puncture needle is withdrawn and slid into a catheter sheath along the guide wire. During the process of inserting the catheter sheath, the catheter sheath will be inserted along the guide of the guide plate 103. At this time, the catheter sheath will be squeezed on the guide plate 103. The squeezed guide plate 103 will drive the connecting frame 102 to open outward. At this time, the opened connecting frame 102 will stretch the spring I 104. Under the elastic force of the spring I 104, the guide plate 103 on the connecting frame 102 will fit inward and limit the catheter sheath, and on the guide plate 10 3, the catheter sheath can be accurately placed in the puncture position. When the catheter sheath is correctly placed, the doctor twists the adjusting thread block 113 to make the rotating adjusting thread block 113 thread drive the threaded rod 112 to move downward, so that the threaded rod 112 drives the pressure plate 111 to contact and limit the position on the catheter sheath to prevent the movement of the puncture sheath during the puncture process. Finally, a thinner catheter is inserted into the catheter sheath that has been fixed in position, and it is guided to the target area. An appropriate amount of contrast agent is injected into the target area through the catheter. Finally, X-rays or digital subtraction angiography technology are used to obtain detailed vascular images, which can help doctors understand the condition of the lesions.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
