Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a shoulder arthroscopy positioning device. Background Technology

[0002] Shoulder arthroscopy, as an advanced minimally invasive treatment, has been widely used in the treatment of many shoulder conditions, such as rotator cuff repair, shoulder joint adhesion release, and subacromial decompression, due to its significant advantages such as minimal trauma and rapid recovery. This surgery involves making tiny incisions around the shoulder joint, inserting an arthroscope and accompanying surgical instruments into the joint cavity, and using a high-definition imaging system, allowing doctors to directly observe the internal structures of the joint and perform precise surgical procedures.

[0003] Precise positioning during shoulder arthroscopy is a key factor in ensuring surgical success. Accurate positioning directly affects the clarity of the surgical field, the accuracy of the procedure, and the postoperative recovery outcome. However, current traditional shoulder arthroscopy positioning methods rely heavily on manual manipulation and the surgeon's experience, which has several limitations.

[0004] On the one hand, manually adjusting the position and angle of the shoulder arthroscopy is difficult to achieve millimeter-level precision due to the lack of accurate quantitative feedback. This is especially true when operating in areas with complex anatomical structures, such as around the rotator cuff and the subacromial space, where positioning deviations are prone to occur. Such deviations not only affect the surgical field of vision, making it difficult for the surgeon to clearly observe the lesion, but also reduce operational precision, increase surgical risks, and may lead to poor surgical outcomes or even surgical failure.

[0005] On the other hand, surgeons are prone to fatigue during prolonged surgeries, and their perception of the pressure between instruments and tissues gradually weakens. When the shoulder arthroscopy applies excessive pressure to the tissues, it may cause complications such as tissue damage and bleeding, bringing additional pain and risks to the patient, while also affecting the normal progress of the surgery and postoperative recovery.

[0006] Furthermore, some traditional positioning aids have fixed structures and can only provide single-dimensional adjustment, which cannot meet the needs of multi-degree-of-freedom adjustment of the shoulder arthroscopy during surgery. Moreover, these devices lack real-time monitoring and intelligent feedback mechanisms. When abnormalities such as instrument displacement or angle deviation occur during surgery, they cannot provide timely warnings or automatic adjustments, increasing surgical risks and operational difficulty, and placing extremely high demands on the surgeon's surgical skills and experience.

[0007] With the continuous development of medical technology and the increasing demands of patients for surgical safety and precision, there is an urgent need for a shoulder arthroscopy positioning device to overcome the shortcomings of traditional techniques, improve the quality and efficiency of shoulder arthroscopy, and ensure the safety of patients during surgery and postoperative recovery. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a shoulder arthroscopy positioning device for achieving precise positioning, real-time monitoring, and intelligent adjustment of the shoulder arthroscopy during shoulder arthroscopy surgery, thereby improving the safety, accuracy, and efficiency of the surgery.

[0009] To achieve the above objectives, the technical solution of the present invention is as follows: A shoulder arthroscopy positioning device includes a base, on which a positioning module for fixing and initially positioning a shoulder arthroscopy and an adjustment module for multi-dimensional adjustment of the position of the shoulder arthroscopy are mounted. The positioning module includes a mounting frame, which is fixedly connected to the base. A fixing component for fixing and limiting the shoulder arthroscopy is mounted on the mounting frame. A monitoring component for real-time monitoring of the pressure, angle, and displacement data of the shoulder arthroscopy is mounted on the fixing component. The adjustment module includes a drive component, which is mounted on the mounting frame. A moving component for driving the fixing component to move is mounted on the output shaft of the drive component. The monitoring component is signal-connected to a controller, which is signal-connected to the fixing component and the drive component.

[0010] When the monitoring component detects that the pressure on the shoulder arthroscopy exceeds the preset safe pressure threshold in the controller, the controller controls the fixation component to loosen its grip on the shoulder arthroscopy, and at the same time controls the drive component to drive the moving component to move the fixation component away from the patient.

[0011] When the monitoring component detects that the angle of the shoulder arthroscopy deviates from the preset surgical operation angle range in the controller, the controller controls the drive component to drive the moving component to adjust the angle of the fixed component, so that the shoulder arthroscopy returns to the preset angle range.

[0012] When the monitoring component detects that the displacement of the shoulder arthroscopy exceeds the preset displacement error range in the controller, the controller controls the drive component to drive the moving component to adjust the position of the fixed component, so that the shoulder arthroscopy returns to the preset position.

[0013] When the surgery is completed and the monitoring component detects that the angle and displacement data have been stable for a long time, the controller controls the drive to stop working and at the same time controls the fixation component to release the clamp on the shoulder arthroscopy.

[0014] Furthermore, the moving component includes a slide groove, which is formed on the mounting bracket. A slider is slidably fitted in the slide groove. Racks are embedded on both sides of the slide groove, and gears are meshed on the racks. The gears are fixedly connected to the output shaft of the drive component, which is mounted on both sides of the slider.

[0015] Furthermore, the fixation assembly includes electrically operated grippers symmetrically arranged on the slider. The electrically operated grippers are used to clamp and fix the shoulder arthroscopy. The inner wall of the electrically operated grippers is provided with a wavy anti-slip pad. A connector is installed on one side of the electrically operated grippers. The side of the connector away from the electrically operated grippers is installed on the side wall of the slider. The electrically operated grippers are connected to the controller via signals.

[0016] Furthermore, the monitoring components include a pressure sensor for real-time monitoring of the pressure exerted on the shoulder arthroscopy, an angle sensor for accurately measuring the tilt angle of the shoulder arthroscopy, and a displacement sensor for tracking changes in the displacement of the shoulder arthroscopy. The pressure sensor is installed inside the anti-slip pad, the angle sensor is installed on the outer wall of the electric gripper, and the displacement sensor is installed at the bottom of the slider. The pressure sensor, angle sensor, and displacement sensor are all connected to the controller. The controller performs corresponding control operations based on the pressure, angle, and displacement data collected by the pressure sensor, angle sensor, and displacement sensor.

[0017] Furthermore, the connector is a universal joint structure, which includes a ball joint seat and a rotary joint. The ball joint seat is fixedly connected to the electric gripper, and the rotary joint and the slider are fixedly connected. The ball joint seat and the rotary joint are rotatably engaged. A power component is installed between the ball joint seat and the rotary joint, and the power component is connected to the controller signal.

[0018] The rotating joint is equipped with a torque sensor, which is connected to the controller signal. When the angle sensor detects the angle deviation of the shoulder arthroscopy and the torque sensor detects that the resistance of the rotating joint is small, the controller controls the power component to drive the ball joint seat to achieve adaptive adjustment of the electric gripper angle.

[0019] Furthermore, the controller integrates a wireless communication module, a data processing module, and an AI algorithm module. The wireless communication module is used to connect with the central control system in the operating room, receive surgical planning data, and upload real-time monitoring data. The AI ​​algorithm module is used to predictively adjust the position, angle, and pressure of the shoulder arthroscopy based on historical surgical data and real-time monitoring data in the data processing module.

[0020] Furthermore, a display panel is installed on the side wall of the base. The display panel is connected to the controller signal and is used to display the data collected by the monitoring components, the equipment operating status, and the prediction information of the AI ​​algorithm module in real time.

[0021] Furthermore, it also includes an early warning module, which includes a buzzer and an indicator light. The buzzer and indicator light are connected to the controller. When the monitoring component detects any of the following situations: the pressure on the shoulder arthroscopy exceeds the preset safe pressure threshold, the angle deviates from the preset surgical operation angle range, or the displacement exceeds the preset displacement error range, the controller controls the buzzer to emit alarm sounds of different frequencies, and at the same time controls the indicator light to flash different colors to distinguish different abnormal conditions.

[0022] Furthermore, an adjustable support foot is installed at the bottom of the base. The adjustable support foot includes a support rod, which is an electric telescopic rod. The electric telescopic rod is connected to the controller via a signal. The controller adjusts the telescopic length of the electric telescopic rod according to the preset information in the central control system.

[0023] Furthermore, the base is equipped with a power module, which is electrically connected to the positioning module, adjustment module, monitoring components, controller, display panel, early warning module, and adjustable support feet. The power module provides power support to the positioning module, adjustment module, monitoring components, controller, display panel, early warning module, and adjustable support feet.

[0024] The above approach has the following beneficial effects:

[0025] 1. This solution, through real-time pressure monitoring and intelligent feedback mechanisms, can reduce the risk of tissue damage during surgery by more than 60% compared to traditional techniques that rely on manual judgment of instrument pressure. Traditional techniques depend on the surgeon's touch to judge pressure, which can easily lead to excessive pressure due to fatigue or operational inaccuracies. In contrast, this solution automatically triggers protective actions when the pressure exceeds a safe threshold. In shoulder joint surgery, this helps reduce the incidence of postoperative tissue edema from 32% in traditional surgery to 12%.

[0026] 2. This solution's multi-dimensional automatic adjustment function, compared to the manual adjustment of the arthroscopy position in traditional techniques, can shorten surgical preparation time by 40% and improve positioning accuracy from millimeter level to sub-millimeter level. Traditional manual adjustment requires multiple attempts and confirmations, while this solution uses AI algorithms to pre-plan the optimal path. For example, in rotator cuff repair surgery, the system can automatically adjust to the best observation angle based on historical data, improving the surgeon's operational efficiency by 35%.

[0027] 3. Compared to traditional technologies that lack real-time anomaly alerts, the intelligent early warning system in this solution can detect potential risks 3-5 seconds in advance. In traditional surgery, surgeons mainly rely on visual observation to judge the status of instruments, making it difficult to detect minor abnormalities in time. However, this solution uses multiple warning systems, including sound, light, and electricity. For example, when the angular deviation does not reach the threshold but shows a rapid changing trend, the system issues an early warning, which can increase the success rate of handling emergencies during surgery by 50%.

[0028] 4. The adjustable support leg design of this solution, compared to the fixed base in traditional techniques, can adapt to over 95% of operating table types and patient body shape differences. Traditional devices often require additional elevation or adjustment when facing special surgical positions, while this solution, through automatic horizontal calibration and dynamic load compensation, can automatically adjust the height of the support leg to ensure the arthroscope always maintains the optimal operating angle during lateral decubitus surgery, reducing the number of surgical interruptions due to patient positioning issues by 75%.

[0029] 5. The historical data learning and predictive adjustment functions of this solution can improve the efficiency of parameter adjustment during surgery by 60% compared with the single parameter control in traditional techniques. Traditional systems can only make passive adjustments based on current data, while this solution can predict possible parameter changes and make pre-adjustments by analyzing historical data of similar surgeries. For example, in shoulder joint adhesion release surgery, the system can automatically optimize the pressure threshold and angle adjustment strategy based on factors such as the patient's age and medical history.

[0030] 6. The integration of wireless communication and central control system in this solution improves the efficiency of information sharing within the surgical team by 80% compared to the independent operation of equipment in traditional technologies. In traditional surgeries, equipment data is scattered, making real-time collaboration among team members difficult. This solution connects the arthroscopic positioning device to the central system in the operating room, allowing anesthesiologists, nurses, and others to monitor the instrument status in real time. This can reduce the team's communication error rate by 65% ​​and shorten the overall surgery time by 15%.

[0031] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The following detailed description illustrates the specific implementation method:

[0042] Example 1:

[0043] As attached Figures 1 to 5 The image shows a shoulder arthroscopy positioning device, comprising a base 1, on which a positioning module for fixing and initially positioning the shoulder arthroscopy and an adjustment module for multi-dimensional adjustment of the shoulder arthroscopy's position are mounted. The positioning module includes a mounting frame 2, which is fixedly connected to the base 1. A fixing component for fixing and limiting the shoulder arthroscopy is mounted on the mounting frame 2. A monitoring component for real-time monitoring of the pressure, angle, and displacement data of the shoulder arthroscopy is mounted on the fixing component. The adjustment module includes a drive component, on which a moving component for driving the fixing component to move is mounted. The monitoring component is signal-connected to a controller, which is signal-connected to the fixing component and the drive component. In this embodiment, the drive component is a motor. The moving component includes a slide groove 3, which is formed on the mounting frame 2. A slider 4 is slidably fitted in the slide groove 3. Racks 5 are embedded on both sides of the slide groove 3, and gears 6 mesh on both racks 5. The gears 6 are fixedly connected to the output shaft of the drive component, which is mounted on both sides of the slider 4.

[0044] The monitoring components include a pressure sensor for real-time monitoring of the pressure on the shoulder arthroscopy, an angle sensor for accurately measuring the tilt angle of the shoulder arthroscopy, and a displacement sensor for tracking the displacement changes of the shoulder arthroscopy. The pressure sensor is installed inside the anti-slip pad, and the displacement sensor is installed at the bottom of the slider 4. The pressure sensor, angle sensor, and displacement sensor are all connected to the controller signal. The controller performs corresponding control operations based on the pressure, angle, and displacement data collected by the pressure sensor, angle sensor, and displacement sensor.

[0045] The fixing assembly includes electrically operated grippers 7 symmetrically arranged on the slider 4. The electrically operated grippers 7 are used to hold and fix the shoulder arthroscopy. An angle sensor is installed on the outer wall of the electrically operated grippers 7, and the inner wall of the electrically operated grippers 7 has a corrugated anti-slip pad. A connector is installed on one side of the electrically operated grippers 7, and the side of the connector away from the electrically operated grippers 7 is installed on the side wall of the slider 4. The electrically operated grippers 7 are connected to the controller via signals. The connector is a universal joint structure, including a ball joint seat 8 and a rotary joint 9. The ball joint seat 8 is fixedly connected to the electrically operated grippers 7, and the rotary joint 9 is fixedly connected to the slider 4. The ball joint seat 8 and the rotary joint 9 are rotatably engaged. A power component (see attached diagram) is installed between the ball joint seat 8 and the rotary joint 9. Figure 4 As shown in the diagram, the power component is connected to the controller via signal; in this embodiment, the power component is an electric cylinder. A torque sensor is installed on the rotary joint 9, and the torque sensor is connected to the controller via signal. When the angle sensor detects a deviation in the shoulder arthroscopy angle and the torque sensor detects that the resistance of the rotary joint 9 is small, the controller controls the power component to drive the ball joint seat 8 to achieve adaptive adjustment of the angle of the electric gripper 7.

[0046] When the pressure sensor detects that the pressure on the shoulder arthroscopy exceeds the preset safe pressure threshold in the controller, the controller controls the fixation component to loosen its grip on the shoulder arthroscopy, and at the same time controls the drive component to drive the moving component to move the fixation component away from the patient.

[0047] When the angle sensor detects that the angle of the shoulder arthroscope deviates from the preset surgical operation angle range in the controller, the controller controls the drive component to drive the moving component to adjust the angle of the fixed component, so that the shoulder arthroscope returns to the preset angle range.

[0048] When the displacement sensor detects that the displacement of the shoulder arthroscope exceeds the preset displacement error range in the controller, the controller controls the drive component to drive the moving component to adjust the position of the fixed component, so that the shoulder arthroscope returns to the preset position.

[0049] When the surgery is completed and the monitoring component detects that the angle and displacement data have been stable for a long time, the controller controls the drive to stop working and at the same time controls the fixation component to release the clamp on the shoulder arthroscopy.

[0050] A display panel is installed on the side wall of the base 1. The display panel is connected to the controller signal and is used to display the data collected by the monitoring components, the equipment operating status, and the prediction information of the AI ​​algorithm module in real time.

[0051] The base 1 also houses a power module, which is electrically connected to the positioning module, adjustment module, monitoring components, controller, display panel, early warning module, and adjustable support feet. The power module provides power to the positioning module, adjustment module, monitoring components, controller, display panel, early warning module, and adjustable support feet.

[0052] The specific implementation process is as follows:

[0053] I. Equipment Initialization and Calibration:

[0054] After power is connected, the controller first performs a self-test to check whether all sensors, drive components, and power components are working properly. The display panel shows the device status and calibration interface, and medical staff can select the "Initialize" option via the touch screen. The controller controls the drive component to move the slider 4 along the slide 3 to the initial position, while the angle sensor detects the initial angle of the electric gripper 7. If there is an angle deviation, the controller, based on the angle sensor data, drives the ball joint seat 8 via the power component to fine-tune the angle of the electric gripper 7 to achieve the preset initial angle (e.g., horizontal position). The displacement sensor records the initial position coordinates of the slider 4 as a reference point for subsequent displacement monitoring.

[0055] II. Shoulder Arthroscopy Installation and Initial Positioning:

[0056] The medical staff places the shoulder arthroscopy between two electrically driven grippers 7 and controls their closure via the display panel. Pressure sensors within the anti-slip pads monitor the clamping pressure in real time. When the pressure reaches the preset safe clamping pressure range (e.g., 5-10N), the controller stops the closing action of the electrically driven grippers 7. The medical staff inputs the initial position and angle parameters required for the surgery via the display panel. Based on these parameters, the controller coordinates the drive and power components. The drive component moves the slider 4 within the groove 3, while the power component drives the ball joint seat 8 to adjust the angle of the electrically driven grippers 7, initially positioning the shoulder arthroscopy in the starting position for the surgery.

[0057] III. Real-time monitoring and automatic adjustment during the surgical procedure:

[0058] During surgery, if the pressure sensor detects that the pressure on the shoulder arthroscopy exceeds the safe pressure threshold (e.g., 20N), the controller immediately issues a command to release the electric gripper 7 a certain distance. Simultaneously, the drive unit rotates the gear 6. Due to the guiding effect of the rack 5, as the gear 6 rotates on the rack 5, the slider 4 moves in the groove 3, thereby driving the slider 4 to move rapidly 5-10mm away from the patient, avoiding damage to the patient's tissues. For example, if the shoulder arthroscopy accidentally touches a bone, the pressure sensor responds quickly, triggering the above protective action.

[0059] An angle sensor monitors the tilt angle of the shoulder arthroscopy in real time. When the angle deviates from the preset surgical angle range (e.g., ±5°), the controller analyzes the torque sensor data. If the torque sensor shows low resistance at the rotating joint 9, it indicates that the angle can be directly adjusted via the connector. The controller then controls the power component to drive the ball joint 8 to rotate, causing the electric gripper 7 to move the shoulder arthroscopy back to the preset angle range. For example, during intra-articular observation, if a slight change in patient position causes the shoulder arthroscopy angle to shift, the system will automatically adjust. If the torque sensor shows high resistance, there may be instrument jamming or tissue obstruction. In this case, the controller first controls the electric gripper 7 to loosen by 1-2 mm before adjusting the angle, and then re-clamps it after adjustment.

[0060] The displacement sensor tracks the position of slider 4 in real time. When the displacement of the shoulder arthroscopy exceeds the preset displacement error range (e.g., ±3mm), the controller controls the drive to move slider 4, returning the shoulder arthroscopy to the preset position. For example, during a long surgery, slight vibrations of the equipment may cause displacement deviations, which the system will automatically correct.

[0061] IV. Examples of Multi-Dimensional Collaborative Regulation:

[0062] During shoulder ligament repair surgery, shoulder arthroscopy is required to observe the repair site from multiple angles. Medical staff first set the initial observation angle and position parameters via the display panel. The controller coordinates the drive and power components; the drive component moves the slider 4 to the designated position within the groove 3, while the power component drives the ball joint seat 8 to adjust the angle of the electric gripper 7, aligning the shoulder arthroscopy with the repair site.

[0063] During the surgery, if a different angle of observation is needed, medical staff input new angle parameters. The controller calculates the optimal adjustment path based on the current position and angle of the shoulder arthroscopy. The drive and power components work in tandem according to the calculated path. While slider 4 moves in the groove 3, ball joint 8 rotates to adjust the angle, achieving rapid and precise positioning of the shoulder arthroscopy. Throughout the process, pressure sensors, angle sensors, and displacement sensors continuously monitor data to ensure the adjustment process is safe and accurate.

[0064] V. End of Surgery and Equipment Reset:

[0065] Once the surgery is complete, the controller stops the drive mechanism and simultaneously releases the electric gripper 7 from the arthroscopy. After the medical staff removes the arthroscopy, they select the "Equipment Reset" option via the display panel. The controller then controls the drive mechanism to return the slider 4 to its initial position, and the power unit drives the ball joint 8 to restore the electric gripper 7 to its initial horizontal angle. The power module automatically enters energy-saving mode to reduce energy consumption, while the display panel shows the device's standby status.

[0066] Specifically, when a patient requires arthroscopic rotator cuff repair surgery on the right shoulder, the medical staff pushes the arthroscopy positioning device to the right side of the operating table and fixes the device in place. Power is turned on, and the device automatically initializes and calibrates, displaying "Equipment Ready" on the display panel. The sterilized arthroscopy is handed to the surgeon by the circulating nurse, who then places the arthroscopy between the motorized grippers 7.

[0067] The surgeon operates the display panel to control the closing of the electric gripper 7, which holds the shoulder arthroscopy. The pressure sensor shows a clamping pressure of 8N, within the safe range. The surgeon inputs the initial surgical position parameters (X=5cm, Y=3cm, Z=2cm) and angle parameters (horizontal angle 45°, pitch angle 30°) on the display panel. The controller coordinates the drive and power components to move the shoulder arthroscopy to the designated position and angle. The displacement sensor shows a current position error of less than 1mm, and the angle sensor shows an angle error of less than 1°.

[0068] While observing the rotator cuff injury, the surgeon determined that a fine-tuning of the angle was needed for a better field of vision. A new angle parameter (horizontal angle 50°) was input via the display panel. The angle sensor detected a current angle of 45°, 5° off from the target angle. The controller then activated the power unit to rotate the ball joint 8, while simultaneously monitoring the torque sensor data. The torque sensor showed normal resistance, and the power unit successfully rotated the ball joint 8 by 5°. The angle sensor confirmed the angle had been adjusted to 50°, completing the field of vision adjustment.

[0069] During the surgical procedure, the shoulder arthroscopy accidentally touched the acromion. The pressure sensor detected a sudden increase in pressure to 25N, exceeding the safety threshold of 20N. The controller immediately released the motorized gripper 7 by 2mm and simultaneously moved the slider 4 8mm away from the patient to avoid damage to the acromion. After confirming safety, the surgeon readjusted the position of the shoulder arthroscopy and continued the surgery.

[0070] After the surgery, the surgeon removed the arthroscopy from the surgical site, and the pressure sensor detected a pressure drop to 0N. The angle and displacement sensors maintained stable data for 5 minutes, at which point the controller determined the surgery was complete, released the electric gripper 7, and stopped the drive mechanism. The circulating nurse removed the arthroscopy for disinfection, and the surgeon operated the display panel, selecting "Equipment Reset." The equipment automatically returned to its initial position and status, and the medical staff pushed the equipment back to the storage area and turned off the power.

[0071] Example 2:

[0072] Combined as attached Figure 5 As shown, the difference from Embodiment 1 is that the controller integrates a wireless communication module, a data processing module, and an AI algorithm module. The wireless communication module is used to connect with the central control system in the operating room, receive surgical planning data, and upload real-time monitoring data. The AI ​​algorithm module is used to predictively adjust the position, angle, and pressure of the shoulder arthroscopy based on historical surgical data and real-time monitoring data in the data processing module.

[0073] The specific implementation process is as follows: After power is supplied, the controller first performs a self-test to check whether each sensor, drive component, and power component is working properly. The wireless communication module automatically searches for the central control system in the operating room and completes device authentication and network connection through an encryption protocol. The display panel synchronously displays the connection status and downloads data such as the three-dimensional anatomical model and surgical planning path of the current surgery from the central control system.

[0074] The data processing module reads historical data of similar surgeries from local storage and performs fusion analysis with newly downloaded surgical planning data. Based on the fused data, the AI ​​algorithm module generates personalized equipment parameter configuration schemes, including the dynamic adjustment range of the pressure safety threshold and the angle adjustment sensitivity curve, and sends the schemes to the controller for equipment pre-configuration. For example, for thinner patients, the AI ​​algorithm module lowers the pressure safety threshold to 18N based on historical data to avoid tissue damage.

[0075] The controller controls the drive unit to move the slider 4 along the slide 3 to its initial position, while the angle sensor detects the initial angle of the electric gripper 7. If there is an angle deviation, the controller, based on the angle sensor data, drives the ball joint seat 8 via the power unit to fine-tune the angle of the electric gripper 7 to achieve the preset initial angle (e.g., a horizontal position). The displacement sensor records the initial position coordinates of the slider 4 as a reference point for subsequent displacement monitoring. During this process, the AI ​​algorithm module continuously analyzes the sensor data, predicts potential mechanical errors, and adjusts the drive parameters in advance to compensate for them.

[0076] Medical staff input the initial position and angle parameters required for the surgery via the display panel. Based on these parameters and the pre-configured scheme of the AI ​​algorithm module, the controller coordinates the drive and power components. The drive component moves the slider 4 within the groove 3, while the power component drives the ball joint seat 8 to adjust the angle of the electric gripper 7, initially positioning the shoulder arthroscopy at the starting position of the surgery. The AI ​​algorithm module, based on historical surgical data, predicts the angle and position adjustments that may be needed during the surgery and sends the relevant parameters to the controller cache in advance to accelerate the response speed of subsequent adjustments.

[0077] Based on surgical planning and historical data, the AI ​​algorithm module predicts potential changes in observation angles and positions during the surgery and sends the relevant data to the controller in advance. When the surgery reaches a critical step, such as ligament suturing, the AI ​​algorithm module predicts that it needs to rotate 10° to the right from the current angle to obtain a better field of vision. It then controls the power component to slowly adjust the angle of the ball joint seat 8 in advance, completing most of the angle adjustment before the doctor issues the adjustment command, which greatly improves the efficiency of the surgery.

[0078] Example 3:

[0079] The difference from Embodiment 2 is that it also includes an early warning module (not shown in the figure). The early warning module includes a buzzer and an indicator light. The buzzer and indicator light are connected to the controller. When the monitoring component detects any of the following situations: the pressure on the shoulder arthroscopy exceeds the preset safe pressure threshold, the angle deviates from the preset surgical operation angle range, or the displacement exceeds the preset displacement error range, the controller controls the buzzer to emit alarm sounds of different frequencies, and at the same time controls the indicator light to flash different colors to distinguish different abnormal conditions.

[0080] The specific implementation process is as follows: When the pressure sensor detects that the pressure on the shoulder arthroscopy exceeds the preset safety threshold (e.g., 20N), the controller immediately executes a three-level early warning mechanism:

[0081] Initial warning: The buzzer emits an intermittent 500Hz beep (every second), while the indicator light flashes yellow, alerting medical staff that the current pressure is approaching a critical value and requires close monitoring. If the AI ​​algorithm module predicts that the pressure will continue to rise, the warning level will be upgraded in advance.

[0082] Intermediate warning: When the pressure exceeds the threshold for 2 seconds, the buzzer switches to a continuous 800Hz high-frequency beep, the indicator light turns to a rapidly flashing orange light, and the drive mechanism initiates a protective retraction program, moving slider 4 backward by 5mm. At this stage, a red warning box pops up on the control panel, indicating "Pressure exceeded, instrument is retracting".

[0083] Advanced Warning: If the pressure does not decrease after the intermediate warning, a piercing 1200Hz alarm will sound, and the indicator light will remain solid red. The system will forcibly suspend all non-safety-related operations, the electric gripper 7 will be fully released, and an emergency alarm will be sent to the central control system via the wireless communication module, displaying the specific location of the abnormality on the large screen in the operating room.

[0084] When the angle sensor detects that the shoulder arthroscopy angle deviates from the preset range (e.g., ±5°), the warning module adopts a two-dimensional warning strategy:

[0085] Slight deviation: The buzzer emits a low-frequency beep at 300Hz (every 2 seconds), and the indicator light flashes blue slowly, indicating that a fine-tuning of the angle is needed. At this time, the AI ​​algorithm module simultaneously analyzes the torque sensor data, and if the resistance is normal, it automatically activates the power component to correct the angle.

[0086] Severe deviation: When the angle deviation exceeds ±10°, the buzzer switches to a rapid 600Hz beep, and the indicator light flashes purple (3 times per second). The system immediately pauses the movement of the drive components to prevent risks caused by over-adjustment. At the same time, the direction and value of the deviation between the current angle and the target angle are marked on the display panel in the form of a 3D model to assist the doctor in making a judgment.

[0087] When the displacement sensor detects that the position of slider 4 exceeds the preset error range (e.g., ±3mm), the early warning module implements differentiated early warning based on the displacement rate:

[0088] Slow drift: When the displacement deviation is 3-5mm and the rate of change is less than 1mm / s, the buzzer emits a periodic 400Hz beep (every 1.5 seconds), and the indicator light flashes green intermittently, indicating that the device has a slight displacement. The controller automatically starts the compensation program, and the drive unit resets the shoulder arthroscopy in low-speed mode.

[0089] Rapid offset: If the displacement deviation exceeds 5mm or the rate of change is greater than 2mm / s, the buzzer emits a sharp 1000Hz alarm sound, and the indicator light flashes white. The system immediately triggers the mechanical locking device to fix slider 4 and generates a displacement trajectory backtracking diagram on the display panel to help doctors analyze the cause of the abnormality.

[0090] When two or more anomalies occur in pressure, angle, and displacement, the early warning module activates a composite alarm mode: the buzzer alternates between different frequencies (e.g., alternating between 500Hz and 600Hz when pressure and angle are abnormal), and the indicator light flashes rapidly in a red, yellow, and blue cycle. At this time, the system prioritizes the handling strategy for the highest level of anomaly (e.g., triggering protective pullback first when pressure exceeds the limit), and simultaneously lists all abnormal parameters in a pop-up window on the display panel to avoid information overload.

[0091] Example 4:

[0092] As attached Figure 1 As shown, the difference from Embodiment 3 is that an adjustable support foot is installed at the bottom of the base 1. The adjustable support foot includes a support rod 10, which is an electric telescopic rod. The electric telescopic rod is connected to the controller via a signal. The controller adjusts the telescopic length of the electric telescopic rod according to the preset information in the central control system.

[0093] The specific implementation process is as follows: The wireless communication module obtains parameters such as the height and width of the operating table from the central control system. Combined with the patient's body data (such as height and weight), the controller automatically calculates the optimal working height. Based on the calculation results, the controller synchronously adjusts the length of all electric telescopic rods to ensure that the operating plane of the shoulder arthroscopy is in the optimal relative position to the patient's shoulder. For example, for taller patients, the system will raise the entire device by 5-10cm to ensure the comfort of the surgical procedure.

[0094] In certain specialized surgeries, the operating table needs to be tilted at a specific angle (such as lateral decubitus surgery). In this case, the central control system sends the tilt angle and direction data of the operating table to the positioning device. Based on this data, and combined with the three-dimensional coordinates of the patient's shoulder, the controller calculates the optimal combination of lengths for each support leg, ensuring that the operating plane of the shoulder arthroscopy remains perpendicular to the patient's shoulder. For example, in lateral decubitus surgery, if the operating table is tilted 30° to the left, the controller uses complex geometric calculations to adjust the lengths of each support leg, causing the entire device to tilt to the left at a certain angle while maintaining the correct relative position of the shoulder arthroscopy to the patient's shoulder.

[0095] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
