Description

Technical Field

[0001] The present invention relates to the technical field of nerve block anesthesia, and in particular to an intelligent auxiliary device for nerve block anesthesia. Background Art

[0002] Nerve block anesthesia is a commonly used local anesthesia method in clinical practice. It is to inject local anesthetics around nerve trunks, plexuses or ganglia, and produce anesthesia in the area controlled by the nerve by blocking the conduction of nerve impulses. It has many advantages. In surgical applications, it can provide good anesthesia conditions for a variety of surgical operations. For example, brachial plexus block can be used for upper limb surgery, and sciatic nerve block can be used for lower limb surgery, reducing the risk of complications of cardiopulmonary and other systems that may be caused by general anesthesia. In addition, patients recover relatively quickly after surgery, and discomfort reactions such as nausea and vomiting are less common. At the same time, for some chronic painful diseases, such as postherpetic neuralgia and trigeminal neuralgia, nerve block anesthesia can be used as an effective treatment method to block the conduction of pain signals and relieve pain. However, nerve block anesthesia is not without risks. The operation process requires precise positioning of the nerves, otherwise it may lead to poor anesthesia or complications, such as nerve damage and local hematoma formation. In addition, toxic reactions may also be caused by drugs entering blood vessels by mistake. Therefore, the operator must have solid anatomical knowledge and rich operating experience, and conduct a comprehensive assessment of the patient before the operation, and prepare appropriate rescue equipment and drugs to ensure the safety and effectiveness of the anesthesia process.

[0003] Traditional nerve block anesthesia often requires the use of ultrasonic imaging for assistance, which requires the doctor to hold the ultrasonic device in one hand and the needle in the other hand to perform the anesthesia operation. Since human hands are prone to fatigue, the pressure of the hand on the ultrasonic device may not be sustained, which may cause inaccurate visualization of the anesthetic needle and nerve position, which may result in poor anesthesia effect.

[0025] Please see attached Figure 2 The intelligent control unit includes an image processing and neural recognition module, a robotic arm control module, and a data storage and communication module. The image processing and neural recognition module is used to process, analyze, and identify the nerve position distribution information in the image. The robotic arm control module is used to generate motion instructions for the robotic arm 2 according to the nerve position information and send them to the robotic arm control system. The data storage and communication module is used to store data during the operation of the system and realize data communication between the various units of the system.

[0026] Specifically, the image processing and nerve recognition module can help medical staff find the patient's nerve location in advance, saving time for subsequent nerve block anesthesia.

[0027] Please see attached Figure 2 -Attached Figure 4 A gear ring 8 is provided on the outer wall of the ultrasonic detector 7, and a horizontal rotation mechanism is provided on the inner wall of the gear ring 8. A fixed frame 9 is fixedly connected to the outer wall of the gear ring 8, and a support leg 10 is fixedly connected to the inner wall of the fixed frame 9. A clamping ring 15 is provided between the two support legs 10. The two clamping rings 15 are slidably connected through a first connecting column 14. The outer wall of the clamping ring 15 is fixedly connected to the output end of the first electric push rod 16. The side of the first electric push rod 16 away from the output end is provided inside the support leg 10, and a lifting mechanism is provided inside the support leg 10.

[0028] Specifically, the gear ring 8 can be used to install the fixed frame 9, the fixed frame 9 can locate the position for medical staff to insert the needle, and the clamping ring 15 can be moved to the position for needle insertion. The support legs 10 can support the clamping ring 15, and the clamping ring 15 can support the anesthetic needle. The first connecting column 14 can enable the two clamping rings 15 to be opened and closed and adjusted while transmitting rotational motion, ensuring that the rotation angles of the two clamping rings 15 are the same. The first electric push rod 16 can push and pull the clamping ring 15.

[0029] Please see attached Figure 2 -Attached Figure 3 The horizontal rotation mechanism includes a first gear 11, the tooth end of the first gear 11 is meshed with the inner wall of the gear ring 8, the first gear 11 is internally fixedly connected to one end of the first transmission shaft 12, the other end of the first transmission shaft 12 is fixedly set at the output end of the first motor 13, and the outer wall of the first motor 13 is fixedly connected to the inner wall of the ultrasonic detector 7.

[0030] Specifically, the rotational force transmitted by the first transmission shaft 12 can be transmitted to the gear ring 8 through the first gear 11, and the rotational force output by the first motor 13 can be transmitted to the first gear 11 through the first transmission shaft 12, thereby driving the gear ring 8 to rotate on the outer wall of the ultrasonic detector 7. When the ultrasonic detector 7 is positioned on the patient's skin, pressure will be applied. At that time, it will be inconvenient for the ultrasonic detector 7 to rotate. The rotation of the gear ring 8 can drive the fixed frame 9 to rotate around the ultrasonic detector 7, thereby assisting medical staff to locate the most suitable needle insertion position. When the medical staff has completed the needle insertion, the anesthetic needle is clamped by the clamping ring 15, thereby maintaining the best position for anesthesia for a long time.

[0031] Please see attached Figure 5 -Attached Figure 8 The lifting mechanism includes a sliding block 20 and a fixed frame 18. The sliding block 20 fits inside the fixed frame 18.

[0032] Specifically, the sliding block 20 can drive the first electric push rod 16 to slide up and down, and then drive the clamping ring 15 to slide up and down, thereby fine-tuning the position of the anesthesia needle and further improving the auxiliary clamping effect. The fixed frame 18 can limit the sliding block 20, so that the sliding block 20 can slide stably axially on the fixed frame 18, and the second motor 22 can output the rotational force, which can be output to the second gear 26 through the second transmission shaft 27, and the rotational force can be transmitted to the tooth end of the rack 39 through the second gear 26, thereby driving the sliding block 20 to move up and down along the rack 39 between the fixed frame 18.

[0034] Specifically, the meshing of the tooth groove 32 and the bar-shaped teeth can enable the second transmission shaft 27 to output the rotational force to the second gear 26, and also allow the second gear 26 to slide on the surface of the second transmission shaft 27. The second electric push rod 21 can output the thrust to the connecting block 23. The connecting block 23 can be used to install the top column 38. The top column 38 is located inside the slide groove 33, so that the second gear 26 can be pushed and pulled by the top column 38 without hindering the rotation of the second gear 26. The meshing state of the second gear 26 can be changed, and it can be meshed with the rack 39 or the third gear 29. The second connecting column 25 can be used to connect the card block 24, and the card block 24 can be used to be stuck on the surface of the rack 39. Therefore, when the second gear 26 is not in the state of the rack 39, the height position of the sliding block 20 can be maintained by the card block 24.

[0035] Please see attached Figure 7 A second limit block 37 is fixedly connected to the outer wall of the second transmission shaft 27, and two second limit blocks 37 are located between the bar-shaped teeth.
