[0062] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0063] One of the optimization directions of the present invention is to further reduce the dependence on assistants by enhancing automated operations, thereby freeing up the surgeon's "vision hand". Specifically, the system introduces an intelligent instrument tracking algorithm in the surgical instrument recognition module, and uses a deep learning model to identify and track the dynamic position of the instrument in real time. Combined with the automatic viewing angle adjustment module, the system can quickly adjust the pitch and rotation angles of the endoscope to ensure that the field of view is always focused on the surgical instrument. In addition, the predictive adjustment system analyzes the movement trajectory and speed of the instrument, adjusts the viewing angle in advance, reduces the system response delay, and achieves real-time tracking of the viewing angle, greatly reducing the frequency of manual adjustment.

[0064] To ensure that the surgical images are clear, the autofocus module has been optimized for accuracy and speed. With the introduction of multi-zone focusing technology, the system can intelligently identify the focus area and adjust the lens focal length in real time according to the position of the surgical instrument in the field of view. At the same time, by optimizing the servo motor control algorithm and combining the AI ​​prediction mechanism, faster focus adjustment can be achieved to avoid focus loss due to the movement of surgical instruments. In addition, the system has continuous focusing capabilities during dynamic surgery, ensuring that doctors can always obtain high-resolution, blur-free surgical images, further improving the smoothness of operation.

[0065] In order to reduce the doctor's cumbersome operation of the system during the operation, the interactive module of the present invention has achieved intelligent upgrades. The system has added a voice command control function, and the doctor can adjust the system through simple voice commands (such as "move left" and "focus") without relying on assistant operations. At the same time, the gesture recognition module is integrated to recognize the doctor's gestures (such as swiping and pointing) through AI algorithms to achieve rapid adjustment of viewing angles, focal lengths and system parameters. The application of the intelligent interactive system further reduces the dependence on assistants during surgery, allowing doctors to focus on surgical operations.

[0066] In order to ensure the real-time and stability of the system, the image acquisition and processing modules have been technically optimized. The system uses parallel processing technology to simultaneously perform image acquisition, AI recognition and feedback tasks through multi-threading, greatly improving the processing speed. In addition, combined with the characteristics of high-resolution CMOS sensors, the system optimizes the frame rate and clarity, so that the picture remains smooth and free of jams even during fast operations. At the same time, the system's efficient feedback mechanism can transmit processed data and images in real time, ensuring efficiency and accuracy during surgery, and further improving the practicality and reliability of the system.

[0112] 7. User Interface

[0113] A touch screen or tablet device is used by the operator to set the initial viewing angle, adjust system parameters, and view system feedback in real time.

[0114] Endoscope body

[0115] The main body of the endoscope consists of a wide-angle lens and an adjustable robotic arm. The wide-angle lens obtains a complete panoramic image of the surgical scene through its wide field of view and transmits the image information to the image acquisition and processing module. The robotic arm is connected to the three-axis electric rotation platform and adjusts the viewing angle of the endoscope in real time according to the instructions of the central control system, so that the lens is always focused on the key area where the surgical instruments are located. The structural design of the robotic arm enables it to move flexibly and achieve three degrees of freedom adjustment: pitch, horizontal and rotation, ensuring that the surgical instruments are always within the optimal observation range of the endoscope.

[0116] Image acquisition and processing module

[0117] The image acquisition and processing module uses a high-resolution CMoS sensor to collect image data of the surgical scene in real time, and uses a built-in AI image processing unit (such as an embedded neural network chip) to process and analyze the image. The acquired images are first preprocessed (such as noise reduction and color enhancement), and then input into the deep learning model for detection and identification of surgical instruments.

The viewing angle adjustment process combines the connection relationship of the instrument (such as the motion trajectory of the operating parts) and functional requirements (such as the operating details of key parts) to achieve dynamic viewing angle tracking and provide the operator with a stable and efficient field of view.

[0124] Central control system and user interface

[0125] The central control system is the core of the entire device, integrating processors, algorithm modules and data interfaces, and is responsible for coordinating the work between various modules. The processor receives data from the image acquisition and processing module, runs the control algorithm, calculates the ideal focal length and viewing angle parameters, and sends instructions to the autofocus module and the viewing angle adjustment module. At the same time, the user interface provides interactive functions through a touch screen or tablet device. The operator can set the initial viewing angle, adjust system parameters, and view system feedback (such as the current viewing angle and focal length status) in real time through the interface. In addition, the user interface also supports manual intervention operations, providing flexible adjustment options for special situations, further improving the adaptability and ease of operation of the system.

[0126] Method steps

[0127] 1. Initialization of surgical scene

[0128] After the system is started, the initial surgical scene is captured through a wide-angle lens, and the central control system pre-processes the captured images to construct an initial three-dimensional space model.

[0129] The user sets the initial observation area and focal length through the interface, or selects automatic recognition mode.

[0130] 2. Real-time Image Acquisition and Analysis

[0131] The image acquisition module acquires real-time surgical scene images at a frequency of 30 frames per second and transmits them to the image processing module.

[0132] The image processing module uses deep learning algorithms to detect and classify surgical instruments and identify their three-dimensional positions in the surgical scene.

[0133] 3. Autofocus

[0134] Based on the position and distance information of the surgical instrument, the central control system calculates the ideal focal length and controls the servo motor to adjust the lens focal length.

[0135] The focus module evaluates image clarity in real time and uses closed-loop control to ensure optimal focus is always maintained.

[0136] 4. Automatic adjustment of viewing angle

[0137] Based on the three-dimensional trajectory of the surgical instrument, the central control system calculates the ideal viewing angle and direction of the endoscope.

[0138] Control the three-axis rotating platform to adjust the pitch angle, horizontal angle and rotation angle of the endoscope to ensure that the surgical instrument is always in the center of the field of view.

[0139] 5. Dynamic adjustment and feedback

[0140] The system continuously acquires images and updates the surgical scene model in real time. When a change in the position of the surgical instrument is detected or the user inputs an adjustment instruction, the viewing angle and focal length are immediately readjusted.

[0141] The user interface displays the current viewing angle and focus status of the endoscope in real time and allows the operator to manually adjust or pause the automatic mode.

[0142] 6. Postoperative Data Storage

[0143] The surgical images and endoscope adjustment trajectory data are stored in the system storage unit for postoperative playback and analysis.
