Detailed implementation manner

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0022] Example 1, please refer to Figure 1 and Figure 2 , a contrast examination device for cardiovascular medicine clinical surgery, including two brackets 1. A contrast component 6 is fixedly connected to the common side of the two brackets 1 close to each other. A regulating component 4 is fixedly connected to the left side of the bracket 1. A sliding component 3 is fixedly connected to the upper end of the regulating component 4. A fixing component 5 is fixedly connected to the front part of the upper end of the sliding component 3. A control component 2 is fixedly connected to the front side of the sliding component 3.

[0023] During the implementation of this embodiment, first, medical staff need to debug the internal parameters of the control component 2. Further, make the patient lie on the upper part of the sliding component 3, put his right arm into the fixing component 5 and fix it. Subsequently, the medical staff can disinfect the patient's right arm to make it meet the puncture contrast standard. Further, the medical staff can adjust the positions of the regulating component 4 and the sliding component 3 through the control system inside the control component 2, so that the sliding component 3 extends to the detection position of the contrast component 6. Subsequently, the contrast component 6 will, under the control of the control component 2, detect the data of the patient for contrast.

[0024] By setting the adjustment component 4 to cooperate with the sliding component 3, when a patient undergoes an examination, due to differences in body height, weight, and build, the device can be flexibly adjusted to ensure the accuracy and comfort of the contrast detection, improving the success rate of the operation. Further, by setting the sliding component 3 to cooperate with the fixing component 5, when fixing the patient's right forearm, fine-tuning can be performed according to its specific size and shape to ensure firm fixation without causing compression, guaranteeing the stability and safety of the patient during the detection process and improving the contrast effect.

[0025] For further reference Figure 3 As shown, the contrast component 6 includes a base 61. An arc is provided on the left side of the bottom of the base 61. A support block 63 is fixedly connected to the upper end of the base 61. A second motor 62 is fixedly connected to the right side of the support block 63. The output end of the second motor 62 is fixedly connected to a transmission shaft through a coupling. A rotating arm 64 is fixedly connected to the right side of the transmission shaft. A third motor 65 is fixedly connected to the rear of the rotating arm 64. The output end of the third motor 65 is fixedly connected to a gear. A C-shaped arm 66 is slidably connected to the left side of the rotating arm 64. The right side of the outer surface of the C-shaped arm 66 is engaged with the gear. An X-ray tube 67 is fixedly connected to the upper left side of the C-shaped arm 66. An image detector 68 is fixedly connected to the bottom left side of the C-shaped arm 66.

[0026] During this implementation process, when medical staff perform a cardiac angiography on a patient, the second motor 62 and the third motor 65 can be precisely adjusted through the control component 2. During the rotation of the second motor 62, the rotating arm 64 will drive the C-shaped arm 66 to rotate around the patient, ensuring that the X-ray tube 67 and the image detector 68 are accurately aligned with the heart area, capturing high-quality contrast images in real time, and improving the diagnostic accuracy. If the debugging result is not satisfactory, medical staff can also finely adjust the rotation angle of the C-shaped arm 66 through the gear fixedly connected to the output end of the third motor 65 until the best contrast effect is achieved, ensuring image clarity and diagnostic accuracy; Further, by setting the gear fixedly connected to the output end of the third motor 65 to cooperate with the right side of the outer surface of the C-shaped arm 66, the C-shaped arm 66 can be kept stable during rotation, avoiding image blurring caused by vibration, ensuring the accuracy of the contrast data. At the same time, the precise cooperation between the gear and the C-shaped arm 66 reduces mechanical errors, improves the overall operating efficiency of the device, and guarantees the smoothness and efficiency of the diagnostic process. In addition, the C-shaped arm 66 can rotate flexibly around the rotating arm 64 to ensure that the X-ray tube 67 and the image detector 68 are accurately aligned with the patient's heart area, obtaining high-definition contrast images in real time, and further improving the diagnostic accuracy and surgical safety; It should be noted that: The C-shaped arm 66 is made of high-strength alloy material, with good fatigue resistance and wear resistance, ensuring no deformation during long-term use. Its surface is coated with an anti-slip coating to increase the operating stability and reduce the risk of accidental sliding; The above is a very mature technical means in the prior art. In this solution, only its function of emitting X-rays is utilized, and its working principle and circuit connection are not elaborated in detail; The above is a mature technical means in the prior art. In this solution, only its function of receiving the X-rays transmitted through the patient's body to form a digital image is utilized, and then the digital image is displayed inside for medical staff to observe and analyze in real time. Here, its working principle and circuit connection are not elaborated; Furthermore, the second motor 62 and the third motor 65 above are both conventional designs in the prior art. In this solution, only their function of transmitting power is utilized, and their working principle and circuit connection are not elaborated in detail.

[0027] For further details, please refer to Figure 4 As shown, the control component 2 includes a support leg 21. A keyboard 22 is fixedly connected to the upper end of the support leg 21. A control terminal 23 is fixedly connected to the right side of the support leg 21. A lead protection shell 24 is provided on the upper end of the control terminal 23.

[0028] During the implementation of this embodiment, it should be noted that the material of the lead protection shell 24 is high-strength lead alloy, which has excellent radiation shielding performance, effectively protecting medical staff from X-ray damage, and at the same time will not affect the operator's line of sight and operation flexibility for pushing the hose of the patient's right arm, ensuring the safety and efficiency of the diagnosis and treatment process. Furthermore, the second motor 62, the third motor 65, the X-ray tube 67, and the image detector 68 mentioned above are all controlled by the keyboard 22 and the control terminal 23. And after the image detector 68 collects the X-ray data penetrating the patient's body, it can be displayed in real time on the display in front of the control terminal 23, which is convenient for medical staff to accurately judge the condition and adjust the treatment plan in time; The control terminal 23 in this solution is a conventional technical means in the prior art. In this solution, only its function of controlling is utilized, and its working principle and circuit connection are not elaborated in detail; Embodiment 2. On the basis of Embodiment 1, this embodiment further realizes the purpose of making adaptive adjustments according to the body shapes of different patients. Please refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, the adjusting component 4 includes two second fixing plates 41. The bottoms of the two second fixing plates 41 are fixedly connected to a lifting plate 43 in common. Both bottoms of the two lifting plates 43 are slidably connected to two mirror-image matching blocks 44. The bottoms of the two second fixing plates 41 are fixedly connected to a transmission component 42 at both ends. The bottoms of the matching blocks 44 on the same side are rotatably connected to a lifting component 45. The transmission component 42 includes two connecting columns 421. A first motor 422 is fixedly connected to the side where the two connecting columns 421 are close to each other. The first motor 422 is wound with two mirror-image first transmission belts 423. The first transmission belts 423 on the sides away from each other are wound with a first threaded rod 424. The right sides of the two first threaded rods 424 are rotatably connected to the right lifting plate 43. The lifting component 45 includes a support shell 451. A first sliding groove 452 is opened at the bottom of the support shell 451. Two first connecting blocks 454 are slidably connected to the inner cavity of the first sliding groove 452. A first shearing plate 455 is rotatably connected to the right side of the front first connecting block 454. A second shearing plate 456 is rotatably connected to the right side of the rear first connecting block 454. Electric telescopic rods 453 are arranged at the upper ends of the two first connecting blocks 454 on the same side. The sliding component 3 includes a sliding pad 31. A first fixing plate 32 is fixedly connected to the right side of the bottom end of the sliding pad 31. Threaded holes 34 are opened at the front and rear sides of the first fixing plate 32. A limiting hole 35 is opened at the front part of the upper end of the sliding pad 31. A pillow 33 is fixedly connected to the right side of the upper end of the sliding pad 31.

[0029] In the implementation process, when the patient needs to adjust the position, the medical staff can start the two electric telescopic rods 453 through the control end 23, so that the two electric telescopic rods 453 contract. During the contraction of the two electric telescopic rods 453, the first connecting blocks 454 installed at the bottoms of the electric telescopic rods 453 will approach each other in the inner cavity of the first sliding groove 452, so that the first shearing plate 455 and the second shearing plate 456 generate relative movement, and then drive the left and right lifting plates 43 to rise, realizing the adjustment of the vertical height of the patient. Further, after the vertical height of the patient is adjusted, the medical staff can control the first motor 422 to rotate the output end through the control end 23. While the output end of the first motor 422 rotates, the two first transmission belts 423 wound on the output end thereof will drive the first threaded rods 424 wound on the other side to rotate. Under the rotation of the front and rear first threaded rods 424, the first fixing plate 32 will drive the sliding pad 31 fixedly connected to the upper end to move towards the imaging component 6, thus realizing the precise adjustment of the horizontal position of the patient; By setting that during the contraction process of the electric telescopic rod 453, it can drive two connecting blocks 454 fixedly connected to the bottom to approach each other, thereby realizing the coordinated movement of the first shear plate 455 and the second shear plate 456. Thus, while the bottoms of the second shear plate 456 and the first shear plate 455 approach each other, their upper parts also approach each other. Furthermore, the verticality of the patient can be adjusted, enabling this device to adapt to the needs of different patients and ensuring the comfort and safety during the treatment process; Further, it should be noted that the electric telescopic rod 453 mentioned above is a conventional technical means in the prior art. In this solution, only its function of transmission is utilized, and its working principle and circuit connection are not elaborated in detail.

[0030] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, this embodiment realizes the purpose of fixing the patient's right arm. Please refer to Figure 8 、 Figure 9 and Figure 10 As shown, the fixing component 5 includes a housing 51. A hemostasis component 52 is slidably connected to the inner cavity of the housing 51. Three limiting blocks 54 are fixedly connected to the bottom end of the housing 51. A clamping component 53 is slidably connected to the inner cavity of the housing 51. The hemostasis component 52 includes a sliding block 521. A support frame 525 is slidably connected to the bottom of the sliding block 521. Sliding grooves 526 are formed on both the front and rear sides of the support frame 525. A second threaded rod 523 is threadedly connected to the upper end of the sliding block 521. A second connecting block 522 is fixedly connected to the upper end of the second threaded rod 523. A hemostasis block 524 is rotatably connected to the bottom end of the second threaded rod 523. The clamping component 53 includes two rotating columns 531. Second transmission belts 532 are wound around both the front and rear sides of the two rotating columns 531. Threaded sleeves 533 are wound around the upper parts of the four second transmission belts 532. Cross-threaded blocks 535 are threadedly connected to the inner cavities of the four threaded sleeves 533. Clamping blocks 534 are fixedly connected to the ends of the two cross-threaded blocks 535 on the same side that approach each other. Third transmission belts 536 are wound around the front parts of the two rotating columns 531. The other sides of the two third transmission belts 536 are commonly wound around a knob 537.

[0031] During the implementation of this embodiment, when medical staff fix the patient's right arm, the transmission belt three 536 can be adjusted by the knob 537. Subsequently, the two transmission belts three 536 will drive the rotating column 531 connected by winding at the bottom to rotate. During the rotation of the two rotating columns 531, the transmission belt two 532 wound around the outer surface can drive the threaded sleeve 533 to rotate. During the rotation of the threaded sleeve 533, the two cross-threaded blocks 535 on the same side are pushed to approach each other, and then the clamping block 534 is pushed to closely fit the patient's right arm to ensure stable fixation. After the cardiac angiography operation on the patient by the medical staff is completed, the slider 521 can be slid to align the hemostatic block 524 with the patient's blood vessel, and the threaded rod two 523 can be driven by rotating the connecting block two 522 to drive the hemostatic block 524 to stop bleeding at the patient's arm, ensuring smooth blood circulation at the operation site of the patient and reducing postoperative complications.

[0032] Through the cooperation of the knob 537 and the transmission belt three 536, the rotation of the rotating column 531 is realized, driving the threaded sleeve 533 to rotate, pushing the cross-threaded block 535 to approach, and then realizing the close fit of the clamping block 534 to the patient's right arm, thereby ensuring the stable fixation of the arm. After the operation is completed, through the cooperation of the slider 521 and the connecting block two 522, the hemostatic block 524 is driven to perform precise hemostasis, ensuring smooth blood circulation at the operation site, effectively reducing postoperative complications, and improving the surgical safety and comfort of the patient.

[0033] The working principle of the present invention will be further elaborated below in combination with Embodiment 1, Embodiment 2, and Embodiment 3: When medical staff perform a cardiac angiography operation on a patient, first, the patient needs to lie on the sliding pad 31. Subsequently, the patient's right arm is disinfected. After disinfection, the patient's right arm is placed in the clamping assembly 53. If the overall position of the fixing assembly 5 makes the patient uncomfortable, it can be adjusted to a suitable position by cooperating with the limiting holes 35 opened on the surface of the sliding pad 31. Further, the transmission belt three 536 is adjusted by the knob 537 to make the clamping block 534 closely fit the arm to ensure stable fixation. Subsequently, through the cooperation of the control terminal 23 and the keyboard 22, the motor one 422 drives the two threaded rods one 424 to rotate through the two transmission belts one 423 wound around the output end. During the rotation of the two threaded rods one 424, they can cooperate with the threaded holes 34 opened on the front and back sides of the fixing plate one 32, so that the sliding pad 31 moves towards the angiography assembly 6. Subsequently, medical staff can directly observe the position of the hose in the patient's body through the display of the control terminal 23 and adjust the depth and angle of the hose in real time to ensure the accuracy of the surgical operation. Subsequently, the medical staff aligns the X-ray tube 67 and the image detector 68 with the patient's heart to perform cardiac angiography on the patient.
