[0002] With the improvement of people's living standards, the number of obese people is increasing, and the difficulty of spinal anesthesia positioning and puncture has increased. This operation needs to be completed by an anesthesiologist with rich experience in spinal anesthesia. Moreover, the puncture is completely based on touch, that is, the touch of breaking through the dura mater to determine whether the puncture is successful. It is completely a blind puncture. With the development of ultrasound imaging technology in recent years, it is now possible to achieve visual and precise spinal anesthesia puncture through an ultrasound machine.

[0003] However, currently, medical ultrasound machines are ultrasound devices for examination, and it is very inconvenient to use them as an aid for spinal anesthesia puncture. For the original puncture operation that requires two hands, one hand needs to hold the ultrasound probe and the other hand needs to perform the puncture operation, which is inconvenient. In addition, the ligaments between the vertebrae in the back are high-density tissue. The ordinary ultrasound machines used for examination are for examining soft tissues, so the imaging is very blurred and only a general view can be seen. Therefore, those skilled in the art have proposed a mobile special ultrasound device for puncture to solve the problems raised in the background art.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It should be noted that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size and illustrated, and any dimensions are only exemplary and not limiting.

[0030] Embodiment 1:

[0031] Please refer to Figure 1 - Figure 6As shown in the figure, a movable special-purpose ultrasound device for puncture includes a support column 1. The bottom of the support column 1 is fixedly connected to a base 2. A leg 21 is fixedly connected to the side of the base 2. A universal wheel 22 is provided at the bottom of the leg 21. A ultrasonic mainframe microcomputer 3 is fixedly connected to the support column 1. An articulated arm 4 is provided outside the support column 1 below the ultrasonic mainframe microcomputer 3. A detection assembly 5 is provided at the end of the articulated arm 4. The detection assembly 5 includes an adjustment member 51 provided at the end of the articulated arm 4. An ultrasonic probe 52 is provided on the adjustment member 51. An observation assembly 6 is provided outside the support column 1 above the ultrasonic mainframe microcomputer 3. The observation assembly 6 includes an arm 61 provided on the support column 1. A display screen 62 is provided at the end of the arm 61. The support column 1 is the main body structure of the entire device, used to connect the base 2, the articulated arm 4, the ultrasonic mainframe microcomputer 3 and the observation assembly 6, playing a role in support and fixation, ensuring the stability of the device and the reliability of operation. The base 2 plays a role in stable support. Its side is connected to the leg 21 and the universal wheel 22, facilitating the movement and fixation of the device, and being suitable for flexible use in different medical scenarios. Among them, the universal wheel 22 is a foot-operated locking setting. The ultrasonic mainframe microcomputer 3 is used as the core component of the device. The ultrasonic mainframe microcomputer 3 is responsible for processing ultrasonic signals, generating images, and displaying them through the display screen 62. It also has intelligent processing functions, such as automatically calculating the depths of the epidural space and the subarachnoid space, providing more accurate auxiliary functions. The ultrasonic mainframe microcomputer converts the original echo signals of the ultrasonic probe into high-resolution two-dimensional or three-dimensional images through a beamforming algorithm, and real-time displays the anatomical structures (such as ligaments, bones, and the trajectory of the puncture needle) at the puncture site. The steps of the image reconstruction algorithm (beamforming) are as follows: Delay and sum: The echo signals of each element in the receiving array are compensated for time delay according to their geometric positions to align the signals from the same target; Signal synthesis: The aligned signals are weighted and summed to enhance the target signal and suppress noise; Dynamic focusing: Dynamically adjust the delay parameters for different depths to optimize the image resolution; The algorithm is: where I(x,z) is the pixel intensity at the coordinate (x,z) in the image, w n is the weight coefficient of the nth element (usually used to suppress sidelobes), s n (t) is the time-domain signal received by the nnth element, x n is the position coordinate of the nth element;

[0032] The robotic arm 4 is used to install and adjust the position and angle of the exploration component 5. It realizes multi-degree-of-freedom movement through multiple joints and connecting plates, can flexibly adjust the position of the ultrasonic probe 52, adapt to the body positions and puncture requirements of different patients. The exploration component 5 is used to explore the puncture site in real time. The adjusting member 51 is used to realize multi-angle adjustment of the ultrasonic probe 52. The ultrasonic probe 52 is used to obtain ultrasonic images of the puncture site, provide more comprehensive real-time images by exploring the sagittal plane and the coronal plane, and ensure the accuracy of puncture. The observation component 6 is used to display the images of the ultrasonic probe 52. The support arm 61 is used to realize multi-angle adjustment of the display screen 62, ensuring that doctors can conveniently observe the images during the operation. The display screen 62 is used to display the images of the ultrasonic probe 52, provide real-time puncture depth, direction and anatomical structure information, and the display screen 62 is provided with a voice control function, so that the ultrasonic instrument can be voice-controlled.

[0033] Specifically, the robotic arm 4 includes a first receiving plate 41 rotatably connected to the support column 1. A fixed shaft 42 is fixedly connected to the end of the first receiving plate 41. A sleeve 43 is sleeved outside the fixed shaft 42. A first fixing plate 44 is fixedly connected to the outside of the sleeve 43. The first receiving plate 41, the fixed shaft 42, the sleeve 43 and the first fixing plate 44 are all used for the connection and support of the robotic arm 4, ensuring the stability and adjustability of the robotic arm 4.

[0034] Furthermore, the robotic arm 4 further includes a first joint 45 and a second joint 46. One end of the first joint 45 is fixedly connected to a first connecting plate 451, and the other end of the first joint 45 is fixedly connected to a second fixing plate 452. One end of the second joint 46 is fixedly connected to a second connecting plate 461. The first joint 45 and the second joint 46 are used to provide multi-angle adjustment functions, enabling the ultrasonic probe 52 to flexibly move to the required position. The first joint 45 and the second joint 46 are connected through the first connecting plate 451, the second fixing plate 452 and the second connecting plate 461.

[0035] Furthermore, multiple legs 21 and universal wheels 22 are provided and are evenly distributed in a circle. The first connecting plate 451 is hinged to the first fixing plate 44, the second fixing plate 452 is hinged to the second connecting plate 461, and the exploration component 5 is arranged at one end of the second joint 46 away from the second connecting plate 461.

[0036] As can be seen from the above, when using this movable special ultrasound device for puncture, doctors can adjust the positions and angles of the ultrasound probe 52 by adjusting the joints of the robotic arm 4 according to the specific body positions of patients and the requirements of the puncture sites. For example, when it is necessary to puncture the spinal canal in the patient's waist, the doctor can first appropriately adjust the angles of the first joint 45 and the second joint 46 of the robotic arm 4 so that the ultrasound probe 52 can accurately align with the spinal canal area in the patient's waist. Through this multi-degree-of-freedom adjustment function, the robotic arm 4 can flexibly move the ultrasound probe 52 to the optimal position, thereby providing doctors with clear and accurate ultrasound images to assist in the puncture operation, solving the problem in traditional puncture operations that doctors need to hold the ultrasound probe 52 with one hand and perform the puncture operation with the other hand, which is inconvenient to operate and prone to fatigue. Moreover, in this embodiment, the robotic arm 4 can fix the ultrasound probe 52, and doctors do not need to hold the probe by hand, thus liberating both hands, enabling more flexible puncture operations, reducing the operation difficulty and the trauma to patients. A disposable sterile plastic film sleeve is also sleeved outside the robotic arm 4, and one end of the disposable sterile plastic film sleeve is in a closed state to meet the sterile principle after the operation;

[0037] The ultrasound probe 52 emits sound waves and receives echoes, and uses the ultrasonic ranging formula: The depth of the puncture needle is calculated in real time, where d is the distance between the target tissue and the ultrasound probe, υ is the propagation speed of ultrasonic waves in human soft tissues, and t is the time interval from the emission of ultrasonic waves to the reception of the reflected signal. Through the improvement of the intelligent system of this device, the imaging of low-density ligaments is faded, and the display of high-density bones and puncture needles is deepened, enabling the boundary of the epidural space and the subarachnoid space to be displayed more clearly, making the position of the needle tip obvious at a glance. The system measures the echo time t, combines the sound speed υ, directly outputs the target depth d, and displays it in real time on the display screen;

[0038] This device automatically calculates the depths of the epidural space and the subarachnoid space and displays them in a corner of the screen. At the same time, it is equipped with color Doppler technology to display blood vessels and drug injection sites in real time, providing doctors with more comprehensive information support. The Doppler frequency shift formula is: Among them, f d is the Doppler frequency shift (unit: Hz), υ is the blood flow or drug flow velocity (unit: m / s), f 0 is the emission frequency of the ultrasound probe (unit: Hz), θ is the angle between the sound beam direction and the blood flow direction (unit: degree), and c is the sound speed (540 m / s).

[0039] Embodiment 2:

[0040] Please refer to Figure 4As shown, this embodiment is basically the same as the previous one, except that the adjusting member 51 includes a first base 511 and a second base 514. The first base 511 is fixedly connected to one end of the second joint 46 away from the second connecting plate 461. A connecting shaft 512 is arranged between the first base 511 and the second base 514. First universal shafts 513 are rotatably connected to both ends of the connecting shaft 512. The first base 511 is used to carry the overall adjusting member 51, the second base 514 is used to carry the ultrasonic probe 52, and the connecting shaft 512 and the two first universal shafts 513 are used to drive the second base 514 to achieve angle adjustment.

[0041] Specifically, a first guide ring 515 and a second guide ring 517 are respectively arranged between the first base 511 and the second base 514. A first connecting rod 516 is rotatably connected to the first guide ring 515, and a second connecting rod 518 is rotatably connected to the second guide ring 517. Both the first guide ring 515 and the second guide ring 517 are used to provide guidance for the connecting shaft 512 in the up, down, left, and right directions. The first connecting rod 516 and the second connecting rod 518 are respectively used to carry the first guide ring 515 and the second guide ring 517, and the first guide ring 515 and the second guide ring 517 can rotate on the first connecting rod 516 and the second connecting rod 518.

[0042] Furthermore, the two first universal shafts 513 are respectively rotatably connected to the ends of the first base 511 and the second base 514, and the ultrasonic probe 52 is arranged on the second base 514.

[0043] As can be seen from the above, during the puncture process, when the doctor needs to make more precise angle adjustments to the ultrasonic probe 52, the adjusting member 51 can be used to achieve this. For example, when the ultrasonic probe 52 needs to explore the spinal canal from the sagittal plane angle, the doctor can adjust the angles of the first universal shaft 513 and the connecting shaft 512 so that the ultrasonic probe 52 can accurately align with the sagittal plane of the spinal canal. At the same time, if exploration from the coronal plane angle is required, the doctor can adjust the angle of the adjusting member 51 again so that the ultrasonic probe 52 can switch to the coronal plane angle. Through this multi-angle adjustment function, the ultrasonic probe 52 can explore the puncture site in real time, detect the needle insertion depth and needle insertion direction of the spinal anesthesia needle in the spinal canal in real time, thereby providing more comprehensive and accurate image information for the doctor, assisting in the precise progress of the puncture operation, and solving the problem that the traditional single probe cannot see the complete depth due to angle limitations, resulting in possible detection dead angles during the puncture process and affecting the accuracy of the puncture. Moreover, the adjusting member 51 in this embodiment can enable the ultrasonic probe 52 to perform multi-angle adjustment, thus solving this problem, improving the accuracy of the puncture, detecting the needle insertion depth and needle insertion direction of the spinal anesthesia needle in the spinal canal in real time, and ensuring that the puncture needle can accurately reach the target site, such as the epidural space or the subarachnoid space.

[0044] Embodiment 3:

[0045] Please refer to Figure 5 - Figure 6 As shown, this embodiment is basically the same as the previous one, except that the support arm 61 includes a second receiving plate 611 rotatably connected to the support column 1, and a connecting seat 612 is rotatably connected to the second receiving plate 611. The second receiving plate 611 is used to receive the overall observation assembly 6, and the connecting seat 612 is used to receive the first support rod 613.

[0046] Specifically, the support arm 61 further includes a first support rod 613 rotatably connected to the connecting seat 612. A receiving seat 614 is fixedly connected to the outside of the first support rod 613, and a second support rod 615 is rotatably connected to the receiving seat 614. A second universal shaft 616 is fixedly connected to the end of the second support rod 615. The receiving seat 614 is used to receive the second support rod 615, and the second universal shaft 616 is used to receive the display screen 62.

[0047] Furthermore, a connecting buckle 621 is fixedly connected to the display screen 62, and a hole is provided in the connecting buckle 621. The end of the second universal shaft 616 is clamped in the hole. Through this structural design, the display screen 62 can be firmly installed on the support arm 61 and can move flexibly with the adjustment of the support arm 61. The connecting buckle 621 is used to fix the connection between the display screen 62 and the support arm 61 to ensure that the display screen 62 will not loosen during the adjustment process.

[0048] As can be seen from the above, during the puncture operation, the doctor needs to flexibly adjust the angle and position of the display according to his own operating habits and the patient's body position in order to better observe the ultrasound image. For example, when the doctor performs a puncture operation on one side of the patient, the doctor can adjust the angles of the second receiving plate 611, the connecting seat 612, the first support rod 613, the receiving seat 614 and the second support rod 615 of the support arm 61 to adjust the display screen 62 to a position where the doctor can observe clearly and comfortably. At the same time, since the second universal shaft 616 is connected to the connecting buckle 621 of the display screen 62, the doctor can further finely adjust the angle of the display screen 62 to ensure that the image can be observed from the best perspective. Through this multi-angle adjustment function, the support arm 61 can ensure that the doctor can always operate in the most comfortable posture and from the best perspective during the puncture process, avoid fatigue caused by frequent movement of the body or head, improve work efficiency, and thus improve the efficiency and accuracy of the entire puncture operation.
