[0130] A connecting ring 46 is fixedly mounted on the outer side of the curved rod 25;

[0131] The frame ring 47 is fixed on the outside of the connecting ring 46 .

[0132] Specifically, the filling cylinder 42 can provide stable support for the guide ring 43, the bent rod 25 can provide a moving guide for the guide ring 43, the guide ring 43 can provide support for the filling cylinder 42, the support 35 can provide support for the positioning ring 44, the bent rod 25 can stably support the connecting ring 46, so that the connecting ring 46 can provide support for the frame ring 47, the frame ring 47 and the positioning ring 44 can provide resistance support and limiting effect for the pull rope 45, so that the pull rope 45 can change the moving direction.

[0133] In actual application of this embodiment, the staff can pull out the plug from the inner side of the filling cylinder 42 according to the actual needs, so as to open the opening of the filling cylinder 42, and then inject ink into the inner side of the filling cylinder 42. The ink will flow into the inner side of the perforation 41 along the filling cylinder 42 under the action of gravity, and pass through the rubber ring 40 through the perforation 41 and flow into the inner side of the bellows 38, so that the bellows 38 and the support 35 cooperate to store ink, and then the plug is inserted back into the filling cylinder 42. The bent rod 25 can provide a through channel and moving space for the bellows 38. When the push rod 34 moves, it will drive the bellows 38 and the rubber ring 40 to move together through the support 35 under the action of external force. The rubber ring 40 will drive the guide ring 43 to move together through the filling cylinder 42, so that the guide ring 43 moves along the outer side of the push rod 34, thereby providing a moving guide and support limit function for the filling cylinder 42.

[0134] In another preferred embodiment of the present invention, the support and rotation member comprises:

[0135] A T-ring 48 is fixed to the bottom ring 29 and is located outside the handle 26;

[0136] A second support ring 54 is fixed to a side of the bottom ring 29 close to the handle 26;

[0137] A circular ring 55, fixed to an end of the second support ring 54 away from the bottom ring 29;

[0138] The annular groove 56 is formed at one end of the handle 26 close to the bottom ring 29 , and the circular ring 55 and the second support ring 54 are located inside the annular groove 56 and are engaged with each other.

[0139] Specifically, the bottom ring 29 can provide stable support for the T-ring 48 and the second support ring 54, the second support ring 54 can provide support for the circular ring 55, the handle 26 can provide a space for the ring groove 56, the ring groove 56 can be engaged with the second support ring 54 and the circular ring 55, and provide movement space and support for the second support ring 54 and the circular ring 55, so that the handle 26 can provide rotational support for the bottom ring 29 through the ring groove 56, the circular ring 55 and the second support ring 54, making the bottom ring 29 more stable without affecting the rotation of the bottom ring 29.

[0140] The pull parts include:

[0141] The rotary sleeve 49 is fixed to the end of the T ring 48 away from the bottom ring 29 and is located outside the handle 26;

[0142] A pull rope 45, one end of which is fixed to the outside of the T ring 48 and is located between the T ring 48 and the bottom ring 29;

[0143] The other end of the pull rope 45 passes through the frame ring 47 and the positioning ring 44, and passes through the positioning ring 44 in a U shape and is fixedly connected to the outer side of the rubber ring 40;

[0144] The limiting component is arranged on the outside of the handle 26 , connected to the rotary sleeve 49 , and corresponds to the position of the pressing handle 32 .

[0145] Specifically, the T-ring 48 can provide support for the rotary sleeve 49. The outer side of the rotary sleeve 49 is relatively rough, which can facilitate the staff to push the T-ring 48 to rotate through the rotary sleeve 49. The T-ring 48 can provide support for one end of the pull rope 45 and can provide a space for winding and winding the pull rope 45. At the same time, the bottom ring 29 and the T-ring 48 can cooperate to provide a resistance for the pull rope 45 to prevent the wound pull rope 45 from slipping out of the T-ring 48.

[0146] The limiting parts include:

[0147] The rubber ring 51 is mounted on the outer side of the rotary sleeve 49 and fits with the rotary sleeve 49;

[0148] The ring plate 50 is fixedly mounted on the outer side of the rubber ring 51 to be frictionally connected with the rotary sleeve 49;

[0149] A support rod 52, one end of which is fixed to the outer side of the ring plate 50, and the other end of which extends to the position corresponding to the pressing handle 32;

[0150] The n plate 53 is fixed to one end of the frame rod 52 close to the pressing handle 32.

[0151] In actual application of this embodiment, a cross opening 36 is formed inside the support 35, and four V-shaped sealing strips 39 are symmetrically fixed on the inner side of the cross opening 36. The four V-shaped sealing strips 39 fit each other and have a certain inclination angle and elasticity, and can use their own elasticity to fit each other to close the cross opening 36. The doctor can push the rotary sleeve 49 according to the needs of actual conditions, so that the rotary sleeve 49 rotates counterclockwise under the action of external force, and uses the rotational power to drive the T-ring 48 to rotate together. The T-ring 48 will drive the bottom ring 29 to rotate under the action of external force, so that the bottom ring 29 drives the second support ring 54 and the circular ring 55 to rotate together, and through the annular groove 56, the bottom ring 29 can rotate under the rotation support of the curved rod 25 under the support of the handle 26. At the same time, the T-ring 48 and the bottom ring 29 will reel in the pull rope 45 during the rotation process, so that the pull rope 45 uses the external force to resist and limit the frame ring 47 and the positioning ring 44 as it is reeled in. The rubber ring 40 is then pulled downward to change the moving direction, so that the pull rope 45 pulls the rubber ring 40 downward, so that the rubber ring 40 overcomes the friction force under the action of external force and moves downward along the push rod 34, and pushes the bellows 38 to fold and deform under the support of the support 35. At the same time, the rubber ring 40 drives the filling cylinder 42 and the plug to move together. In the process of the bellows 38 folding and deforming, the space inside it will be gradually compressed, and under the sealing action of the plug and the rubber ring 40, the bellows 38 pushes the air inside it while being squeezed, folded and deformed, so that the air pushes the ink stored in the bellows 38, and the ink pushes the V-shaped sealing strip 39 to deform under the action of pressure, thereby opening the cross-mouth 36, so that the ink in the bellows 38 can pass through the cross-mouth 36 under the action of gravity and be filled onto the fiber pen tip 37, so that the fiber pen tip 37 can obtain the ink for marking, which is convenient for adding ink after the ink in the fiber pen tip 37 is used up, providing convenience for marking;

[0152] When the rotary sleeve 49 is pushed to rotate counterclockwise, the rotary sleeve 49 will use the friction force with the rubber ring 51 to drive the ring plate 50 to rotate together, so that the ring plate 50 drives the frame rod 52 to rotate together by external force, and at the same time, the frame rod 52 drives the plate 53 to rotate counterclockwise under the action of external force, so that the plate 53 moves and sleeves on the outside of the pressing handle 32 to prevent the pressing handle 32 from moving downward, and then the rotary sleeve 49 continues to be pushed to rotate, and uses the rotational power to overcome the friction with the rubber ring 51, so that the rotary sleeve 49 The rubber ring 51 rotates on the inner side, and the ring plate 50 and the rubber ring 51 do not rotate with the rotating sleeve 49 under the resistance of the n plate 53, the pressure handle 32 and the frame rod 52. When the rotating sleeve 49 rotates, the end of the spring 30 away from the top plate 31 will be pulled through the bottom ring 29 to rotate together on the inner side of the handle 26. At the same time, the pressure handle 32 and the handle 26 will provide resistance for the top plate 31 to prevent the end of the spring 30 away from the bottom ring 29 from rotating, so that the spring 30 is pulled by the rotational force to deform and store energy.

[0153] After adding ink to the fiber pen tip 37, the staff can loosen the rotary sleeve 49 to release the external force applied to the spring 30 by the rotary sleeve 49. At this time, the spring 30 will rebound with the rebound force under the support of the top plate 31, and push the bottom ring 29 to rotate clockwise. At the same time, the bottom ring 29 will drive the T-ring 48 and the rotary sleeve 49 to rotate together, and then release the wound pull rope 45, so that the corrugated tube 38 will rebound upward along the push rod 34 by its own elastic force, and pull the pull rope 45 to reset. At the same time, the rotary sleeve 49 will rotate clockwise and use the friction force with the rubber ring 51 to drive the frame rod 52 and the n plate 53 to rotate together, so that the n plate 53 is moved away from the outside of the pressing handle 32, thereby releasing the resistance limit on the pressing handle 32.

[0154] Another preferred embodiment of the present invention provides a color ultrasound image recognition training device, comprising:

[0155] The image recognition camera 13 is installed at an appropriate position to ensure that the chest color ultrasound image can be clearly captured; when the chest color ultrasound examination is performed, the camera 13 will capture the output image of the color ultrasound device in real time; the captured image and the marks in the image (such as the position of key structures such as blood vessels and nerves) are transmitted to the host 6 in real time for subsequent processing;

[0156] After receiving the image data from the camera 13, the host 6 first performs standardization processing; the standardization processing includes adjusting the image size to meet the requirements of subsequent processing; performing color correction to eliminate the influence of factors such as lighting and contrast on image quality; next, the host 6 will perform data enhancement operations on the image, including rotation, cropping, scaling and other means to expand the data set and improve the generalization ability of the model. The processed image data set is stored in the host 6.

[0157] Import the SIFT algorithm library and create a SIFT object for subsequent feature point detection. Load the chest color ultrasound image and grayscale the image, because SIFT usually operates on grayscale images. Perform denoising on the image to reduce the impact of noise on feature point detection. Use the SIFT object to detect feature points on the preprocessed image. The SIFT algorithm will search the image at different scales to find scale- and rotation-invariant feature points. From the detected feature points, select the feature points corresponding to the bifurcation of blood vessels, the obvious bends or intersections of nerve fibers. This can be achieved by analyzing the local image features around the feature points (such as gradient direction, intensity change, etc.). Record the position, scale, direction and other information of the selected feature points for subsequent use.

[0158] Initialize the Canny edge detector, including:

[0159] Import the Canny edge detection algorithm library (such as the Canny() function in OpenCV); set two thresholds (low threshold and high threshold) for Canny edge detection for hysteresis threshold processing of edges; if grayscale processing has not been performed before, convert the image to grayscale now and perform Gaussian filtering on the image to reduce the impact of noise on edge detection; use the Canny edge detector to detect edges on the preprocessed image. The Canny algorithm will find strong and weak edges in the image and connect the edges according to the set threshold; extract linear structures from the detected edges, which can be achieved through the Hough Transform algorithm; linear structures usually correspond to blood vessels in ultrasound images, so you can focus on long and continuous line segments; record the position, length, direction and other information of the extracted linear structures, which can be used for subsequent blood vessel positioning and labeling.

[0160] Based on the extracted line features and combined with the characteristics of color Doppler ultrasound (such as information on blood flow direction and speed), the position of blood vessels can be accurately located; for example, red or yellow color spectrum usually indicates blood flow toward the probe, and blue or blue-green color spectrum indicates blood flow away from the probe. This information helps to confirm the position and direction of blood vessels; nerves usually appear as cord-like or circular structures in ultrasound images; by identifying these specific shaped structures and combining them with prior knowledge of anatomy, the position of nerves can be located; once the blood vessels and nerves are accurately located, annotation tools (such as rectangular boxes, polygonal boxes, etc.) can be used to annotate them on the image; these annotations can clearly indicate the exact location of blood vessels and nerves, facilitating doctors to conduct further analysis and diagnosis.

[0161] The vascular and nerve positioning auxiliary system is seamlessly integrated with the color Doppler ultrasound device. When performing a chest color Doppler ultrasound examination, the doctor can view the annotated information of the blood vessels and nerve positions in real time through the display screen of the color Doppler ultrasound device. At the same time, an intuitive and easy-to-use user interface facilitates the doctor's interactive operations and data viewing.

[0162] Working principle: the support frame 1 can provide a stable support for all the facilities fixed on its inner and outer sides, and provide a rotation support for the roller rod 2. The staff can control the motor 4 to start under the support of the support frame 1 according to the actual situation, so that the motor 4 drives the transmission 5 to rotate, changes the rotation speed and drives the roller rod 2 to rotate. The roller rod 2 uses the rotational power and friction force under the support of the support frame 1 to push the conveyor belt 3 to rotate clockwise, thereby transmitting the color ultrasound image placed above it from left to right. During the transmission process, the staff can control the extension and retraction of the electric rod 11 under the support of the guide frame 10 to push the support plate 12, so that the image recognition camera 13 moves to a suitable height to shoot the transmission. The conveyor belt 3 transmits the color ultrasound image, identifies the mark on the image, and transmits the image and the mark to the host 6; after the host 6 calculates, it uses the image and the mark to train the AI ​​machine, and transmits the picture to the display screen 8 for the staff to refer to, so that the AI ​​machine can be applied to actual surgery after training and learning a large number of color ultrasound images. During the operation, the blood vessels and nerves in the color ultrasound image are identified and located in real time according to the mark content of the training for the doctor's reference, which is convenient for the doctor to find the best puncture site and avoid damaging the blood vessels and intercostal nerves. When the doctor needs to perform marking training on the color ultrasound image, he can hold the handle 26 with his hand and judge whether the conveyor belt 3 drives the conveyor belt 3 according to the picture on the screen 17. The position of the color ultrasound image is moved. When it moves to the appropriate position, the doctor presses the switch 27 on the handle 26 to control the motor 4 to stop, so that the color ultrasound image stays at the appropriate position. Then, the doctor pushes the bending rod 25 through the handle 26, uses external force to push the telescopic rod 24 to extend or contract, and pushes the three-convex frame 22 at the same time, so that it drives the roller 21 to move forward and backward along the guide groove 20. In this way, the support of the bending rod 25 and the handle 26 allows the steel wire 33, the push rod 34 and the fiber pen head 37 to move to the corresponding position on the color ultrasound image. The doctor then presses the pressing handle 32 with his thumb, and the pressing handle 32 moves downward along the through hole 28 under the action of external force to push the top plate 31. Then, the top plate 31 squeezes the spring 30 to contract, pushing the steel wire rope 33 downward, causing the push rod 34 to drive the support 35 and the fiber pen tip 37 to move downward. At this time, the fiber pen tip 37 leaves ink at the contact position with the color ultrasound image to mark the corresponding position on the color ultrasound image. When the doctor removes his hand from the pressure handle 32, the spring 30 uses its own rebound force to push the top plate 31 upward, causing the top plate 31 to drive the steel wire rope 33, the push rod 34 and the fiber pen tip 37 to reset for use next time marking. The staff can also inject ink into the ink storage part as needed, so that the bellows 38 can store ink, and mark the color ultrasound image through the above marking process when needed.

[0163] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
