Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to an intelligent shoulder abduction brace. Background Art

[0002] During the rehabilitation process after shoulder joint surgery, patients often need to use some auxiliary tools to protect and fix the shoulder joint to facilitate wound healing and promote recovery. Especially after shoulder surgery, the abduction movement of the shoulder joint is greatly restricted. If it is not properly fixed, it may cause secondary damage to the surgical site, thereby prolonging the recovery period and even having consequences that are not conducive to recovery. Therefore, an intelligent shoulder abduction brace is proposed, which can effectively fix the shoulder joint, especially a brace that limits its abduction degree, which is crucial to improving the success rate of surgery and accelerating postoperative recovery.

[0003] A new type of shoulder abduction brace with the announcement number CN119157680A has solved the technical disadvantage of being only able to fix and support the joints and arms and being too single. However, in actual use, similar structures still have many defects. For example, the existing brace cannot monitor the patient's shoulder joint angle and pressure in real time during the support process, making the patient's local pressure changes and angle changes difficult to predict, resulting in instability of the shoulder joint fixation angle and insufficient lifting force, and unable to ensure the correctness of the shoulder joint fixation and promote effective rehabilitation progress; and lacks real-time feedback and data sharing functions, and cannot comprehensively monitor the patient's treatment effect and status, and cannot understand their own rehabilitation progress in real time. It is also not convenient for medical staff to understand the patient's rehabilitation status based on real-time data, thereby affecting the efficiency and effectiveness of treatment.

[0004] Therefore, the above technical problems need to be solved. Summary of the Invention

The first encoder 704 is sleeved on the outside of the spline shaft 703.

[0044] The third transmission assembly 702 is capable of rotating and transmitting torque, driving the spline shaft 703 to rotate. The rotation of the spline shaft 703 drives the boom lifting assembly 801 to rotate inward through the spline groove plate 8013 connected by the bayonet pin, thereby adjusting the inward rotation angle. When the spline shaft 703 rotates, the angle of the spline shaft 703 is monitored in real time by the first encoder 704, and the adjusted angle is fed back to the control module 504 to ensure the accuracy and reliability of the operation.

[0047] The abduction angle adjustment mechanism 6 drives the arm lifting mechanism 8 to adjust the abduction angle, and the second encoder 8012 monitors the adjustment angle in real time, so as to achieve the purpose of accurately controlling the adduction and abduction angles of the shoulder joint; the internal rotation angle adjustment mechanism 7 drives the arm lifting mechanism 8 to adjust the internal and external rotation angles, and the first encoder 704 monitors the adjustment angle in real time, so as to achieve the purpose of accurately controlling the internal rotation and external rotation angles of the shoulder joint; and the pressure sensor 8052 is used to detect the pressure on the arm fixing sleeve 805 in real time; and the pressure sensor 8052, the first encoder 704, and the second encoder 8012 transmit the monitoring electrical signals to the control module 504, and the control module 504 calculates the fixation effect and rehabilitation effect of the brace according to the measured angle and pressure;

[0048] Among them, the abduction angle adjustment mechanism 6 is responsible for controlling the adjustment of the abduction and adduction angles of the arm lifting mechanism 8. By driving the abduction angle adjustment mechanism 6, the position of the arm can be adjusted so that it reaches the required angle in the abduction direction, and the second encoder 8012 monitors the angle changes during the adjustment process in real time to ensure the accuracy of the angle adjustment; on the other hand, the internal rotation angle adjustment mechanism 7 also drives the arm lifting mechanism 8 to adjust the internal rotation and external rotation angles, and the angle changes are monitored in real time by the first encoder 704 to ensure accurate control of the internal rotation and external rotation angles of the shoulder joint;

[0049] The abduction angle adjustment mechanism 6 and the internal rotation angle adjustment mechanism 7 respectively drive the arm lifting mechanism 8 to adjust the angle in the abduction, internal rotation and external rotation directions, while the second encoder 8012 and the first encoder 704 are each responsible for monitoring the angle changes in the corresponding directions, thereby achieving precise control of the shoulder joint angle adjustment;

[0050] The pressure sensor 8052 is responsible for real-time detection of the pressure on the arm fixing sleeve 805 to ensure the safety and comfort of the lifting and fixing process;

[0051] The monitoring signals of each component are collected and processed by the control module 504 to calculate the fixation effect and rehabilitation effect of the brace. These data are synchronized to the cloud database through the wireless communication module 503 for remote viewing by doctors and rehabilitation therapists, thereby realizing remote monitoring and management.

The spline groove plate 8013 is tightly combined with the spline shaft 703 through the spline structure, so that the spline shaft 703 can drive the first support plate 8011 to rotate through the spline groove plate 8013.

[0054] like Figure 12 As shown, the T-shaped shaft member is composed of a rotating shaft member and two side shaft members, the two side shaft members are fixedly mounted on both ends of the rotating shaft member, the rotating shaft member is rotatably connected to the side of the mounting shell 5, and the axis of the rotating shaft member connected to the mounting shell 5 is on the same horizontal axis as the axis of the spline groove plate 8013;

[0055] Among them, the two side shafts are rotatably connected to one end of the first support plate 8011 through a shaft, which facilitates the angle adjustment of the first support plate 8011; and are rotatably connected to the side of the mounting shell 5 through a rotating shaft, and the axis of the connection between the rotating shaft and the mounting shell 5 and the axis of the spline groove disk 8013 are on the same horizontal axis, so that the first support plate 8011 can be rotated through the spline groove disk 8013 and the spline shaft 703; so that the arm lifting mechanism 8 can be driven to adjust the angle in the abduction, internal rotation and external rotation directions through the abduction angle adjustment mechanism 6 and the internal rotation angle adjustment mechanism 7 respectively.

[0056] like Figure 10 As shown, the rotating mechanism 802 consists of a turntable cover 8021, a lifting plate 8022 and an adjusting turntable 8023.

Rotating the locking knob unlocks the adjustment dial 8023, and the pointer is driven to move on the scale dial by rotating the adjustment dial 8023. When the pointer reaches the specified position on the scale dial, the adjustment dial 8023 is locked by rotating the locking knob in the opposite direction, thereby achieving the purpose of adjusting the angle of the forearm lifting component 803 and the upper arm lifting component 801, and realizing the flexion and extension adjustment of the elbow joint.

[0058] like Figure 11 As shown, the forearm lifting assembly 803 consists of a second extension plate 8031, a second positioning sleeve 8032 and a second support plate 8033.

The position of the second extension plate 8031 ​​can be locked by rotating the locking knob in the opposite direction.

[0060] The duration monitoring module 8042 uses a combination of a flexible film pressure sensor and an ADXL345 three-axis acceleration sensor; the flexible film pressure sensor monitors the contact status to ensure that the brace is worn correctly; the ADXL345 three-axis acceleration sensor detects the static or moving state of the brace based on the principle of gravity acceleration, and combines with the built-in 9-axis posture module (such as MPU9250) of the control module 504 to calculate the joint range of motion in real time to assist in verifying the effectiveness of wearing; the flexible film pressure sensor and the ADXL345 three-axis acceleration sensor are used to comprehensively judge the wearing duration and compliance to avoid the risk of misjudgment of a single sensor.
