The rear ends of the five groups of first fixing members 501 are fixedly connected to a first connecting pipe 6, and the rear end of the first connecting pipe 6 is fixedly connected to a second connecting pipe 7. As Figure 4 shown, this structure is used to connect with the device through the second connecting pipe 7, control the pressure of the inflatable silica gel tube 503, drive the bionic tendon, and make the finger sleeves 4 assist in flexion and extension according to a preset trajectory, support independent training of five fingers, be compatible with VR gamified rehabilitation scenarios, and connect with a VR glasses via Bluetooth of the device, enabling the patient to enter a VR virtual scenario such as screwing the cap of a bottle or typing, enhancing the immersion feeling with the VR glasses, adding fun to the exercise, and avoiding mental fatigue of the patient caused by too long exercise time.

[0023] Further, a protective layer 9 is fixedly connected to the inner wall of the finger sleeve 4, and a micro piezoelectric film 10 is installed at the movable joint position of the finger sleeve 4. As Figure 5 shown, this structure is used to capture the pressure distribution through the micro piezoelectric film 10 inside the finger sleeve 4 when the patient exercises the fingers, automatically generate a dynamic matching resistance curve on the display screen at the control system, and make adjustments according to the generated structure to strengthen specific muscle groups. It can also avoid secondary trauma during the exercise according to the joint range of motion heat map, grip strength symmetry analysis, and fatigue index warning.

[0024] Further, protrusions 804 are provided on the inner walls of the arm fixing ring 1 and the exercise glove 3. The protrusions 804 are installed on the path of the airbag 802, and the protrusions 804 are semi-circular. As Figure 3 shown, this structure is used to drive the protrusions 804 when the airbag 802 expands through the setting of the protrusions 804, press the acupoints on the hand, so as to stimulate the corresponding meridian acupoints and indirectly regulate the visceral functions of the lungs and large intestine.

Furthermore, corresponding movable holes 11 are provided at the bottom of the finger sleeve 4 corresponding to the joint positions. The movable holes 11 are oval-shaped, and a heating component is also installed inside the finger sleeve 4, which can heat the finger part to improve the comfort of the patient. As Figure 4 shown, this structure is used to facilitate the entry of weak fingers into the corresponding finger sleeves through the movable holes 11. When the finger joints bend, the fingers can move freely, avoiding restraint on the fingers and improving the comfort of the device.

[0027] Working principle: When in use, as Figure 1 shown, pass the patient's hand through the arm fixing ring 1, the wrist outer ring 2 and the exercise glove 3, then put the patient's fingers into the corresponding finger sleeves 4, and then connect the third connecting pipe 803 and the second connecting pipe 7 to the device. When exercise is needed, first perform preheating, start the heating sheet 12 to apply hot compress to the hand, so that the internal temperature reaches 40 - 45 °C and wraps the finger joints for 5 minutes to promote blood circulation, and then perform the massage step, as Figure 3 shown, inflate and deflate the inside of the airbag 802, so that the arm fixing ring 1 and the exercise glove 3 expand and release. When the airbag 802 expands, drive the protrusion 804 to knead from the fingertip to the palm direction for 2 minutes to promote tissue blood flow, and at the same time press the acupoints on the hand, causing stimulation to the corresponding meridian acupoints, and indirectly regulating the functions of internal organs such as the lungs, large intestine, and pericardium; then start the air pump, as Figure 4 and Figure 5 shown, control the pressure of the inflatable silica gel tube 503 through the second connecting pipe 7 and the first connecting pipe 6, drive the bionic tendon, and make the finger sleeve 4 assist in flexion and extension according to a preset trajectory. Inflate the inflatable silica gel tube 503 to pressurize, and cooperate with the first linkage 502 and the second linkage 505 to achieve 0 - 90° flexion angle control. Combine the micro piezoelectric film 10 to monitor the grip force in real time and automatically adjust the resistance, so that the fingers complete in sequence (palmar flexion: the air pressure pushes the fingers to bend towards the palm to the maximum angle (maintain for 10 seconds); dorsal extension: the reverse air pressure stretches the fingers to the dorsal limit (maintain for 10 seconds); number of cycles: 10 times per group, 2 - 3 groups per day). Then perform active assisted training, opposition exercise: the thumb alternately touches the other four fingers, 15 times per group; joint extrusion: use a massager to slide the interphalangeal joints laterally to enhance stability. Final relaxation, cold and heat alternation: apply ice compress to the joints for 5 minutes after training (prevent inflammation), and then apply hot compress for 5 minutes (relieve stiffness); finger extension: open the five fingers to the maximum extent and maintain for 10 seconds, repeat 5 times. The above is the entire working principle of the present invention.
