[0033] Ultrasound probe 1, fixing device 2, cable 3, puncture needle 4, anesthetic drug injection channel 5, sensor 6, encoder 7, high-performance processor 8, human-computer interaction interface 9, robotic arm 10;

[0034] A robotic arm 10 is fixed above the human-machine interaction interface 9 by screws; a high-performance processor 8 is embedded on the front of the robotic arm 10; the high-performance processor 8 is respectively connected to the ultrasound probe 1, the sensor 6, and the encoder 7 through cables 3; a puncture needle 4 is provided at the front end of the robotic arm 10; and the ultrasound probe 1 is fixed to the front end of the robotic arm 10 by a fixing device 2.

[0035] The right side of the fixing device 2 provided in the embodiment of the utility model is fixed with a sensor 6 by screws.

[0036] An encoder 7 is embedded on the right side of the sensor 6 provided in the embodiment of the utility model.

[0037] The puncture needle 4 provided in the embodiment of the utility model is provided with an anesthetic injection channel 5 .

[0038] The utility model is specifically implemented as follows:

[0039] 1. Design and implementation of ultrasound probe 1

[0040] The ultrasound probe 1 uses a high-frequency linear array probe, which can obtain high-resolution ultrasound images to more accurately display the target nerve and its surrounding tissue structure. The probe is designed with a special fixing device 2, which can be stably fixed on the mechanical arm 10 to ensure that it will not move during the puncture process.

[0041] The ultrasonic probe 1 is connected to the control system via a cable 3 to transmit image data in real time. The control system has a built-in image processing algorithm that can automatically analyze the image data, identify and mark the location and depth information of the target nerve.

[0042] 2. Design and implementation of puncture needle 4

[0043] The puncture needle 4 adopts a special slender structure, and the needle tip is designed to be flexible to meet the puncture requirements of different parts. An anesthetic drug injection channel 5 is arranged inside the puncture needle 4 to ensure that the drug can be accurately injected around the target nerve.

[0044] The puncture needle 4 is connected to the mechanical arm 10 through a precise connection mechanism, which can realize the precise movement of the needle tip in three-dimensional space. The mechanical arm 10 adopts a multi-joint design and is driven by a servo motor to realize multi-degree-of-freedom control of the puncture needle 4.

[0045] 3. Design and implementation of robot arm 10

[0046] The mechanical arm 10 is made of lightweight materials to reduce the impact on the operation accuracy. The mechanical arm 10 is internally integrated with a sensor 6 and an encoder 7, which can provide real-time feedback on the position and posture information of the mechanical arm 10 to ensure that the puncture needle 4 can accurately reach the target position.

[0047] The mechanical arm 10 is driven and controlled by a control system. The control system calculates the motion trajectory and speed of the mechanical arm 10 according to the image data of the ultrasound probe 1 and the operation instructions of the doctor, and then drives the mechanical arm 10 to move accurately through the motor driver.

[0048] 4. Design and implementation of control systems

[0049] The control system is the core part of the entire device, which is responsible for receiving image data from the ultrasound probe 1, processing data, analyzing the location of the target nerve, and controlling the mechanical arm 10 to drive the puncture needle 4 for precise puncture.

[0050] The control system uses a high-performance processor and image processing algorithm, which can process ultrasound image data in real time and accurately identify the location and depth information of the target nerve. At the same time, the control system also has a human-computer interaction interface 9, which can display ultrasound images, puncture paths, puncture depth and other information to facilitate doctors to operate and monitor.

[0051] During the operation, the doctor can set the puncture target point through the human-machine interface 9 of the control system, and the control system will automatically calculate the best puncture path and puncture depth, and control the mechanical arm 10 to drive the puncture needle 4 for precise puncture. At the same time, the control system can also monitor various parameters during the puncture process in real time, such as puncture speed, puncture depth, etc., to ensure the safety and accuracy of the puncture process.
