For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] As Figures 1-5As shown, the present application provides a technical scheme: a finger nerve injury rehabilitation auxiliary equipment with safety protection function, including finger rehabilitation mechanism 1 and controller 2, finger rehabilitation mechanism 1 includes finger bending / straightening device 11, the number of finger bending / straightening device 11 is three groups, finger bending / straightening device 11 includes DC motor 101, drive gear 102, fixed spring 106;The bottom of DC motor 101 is detachably connected with base 3, the bottom of base 3 is detachably connected with first bandage 4, drive gear 102 is fixedly sleeved on the output end of DC motor 101, the base 3 is provided with a movable slot, the movable slot is movably connected with transmission rack 103, the right end of transmission rack 103 is fixedly connected with driving sliding spring 104;The end of driving sliding spring 104 away from transmission rack 103 is detachably connected with fixed block 105, one end of fixed spring 106 is fixedly connected with the right side of base 3, the other end of fixed spring 106 is detachably connected with the left side of fixed block 105, and is located below driving sliding spring 104;The bottom of fixed block 105 is fixedly connected with finger sleeve ring 107, and force sensor 6 is arranged on finger sleeve ring 107;The number of force sensor 6 is several;Three groups of finger bending / straightening device 11 are detachably connected on base 3 through the right end of driving sliding spring 104 and fixed spring 106 in turn;The both ends of controller 2 are fixedly connected with second bandage 5 respectively, the front of controller 2 is provided with display screen 7 and function key 8, and the top of controller 2 is provided with control interface 9;The inside of controller 2 is provided with rechargeable battery, and controller 2 is electrically connected with DC motor 101 through control interface 9;The second bandage 5 is provided with magic tape.

[0027] The finger nerve injury rehabilitation auxiliary equipment with safety protection function, when the patient wears the rehabilitation equipment, tries to bend the required recovery finger, the monitoring value of the force sensor 6 attached to each finger sleeve ring 107 changes, the controller 2 drives the finger joints to bend through accurate analysis; when the patient tries to stop bending, the change of the monitoring value of the sensor 6 on each finger sleeve ring 107 makes the controller 2 judge the intention of the patient, so as to stop the bending action; when the patient tries to straighten the finger, the change of the monitoring value of the sensor 6 on each finger sleeve ring makes the controller 2 drive the finger joints to straighten through accurate analysis; when the patient tries to stop straightening, the change of the monitoring value of the sensor 6 on each finger sleeve ring makes the controller 2 judge the intention of the patient, so as to stop the straightening action; in the process of bending or straightening the patient's finger, the controller 2 continuously collects and processes the changing signals to determine the recovery status of the finger joints, so as to adjust the angle and speed of bending and straightening of the joint in time. The bending action of the finger joint is that the DC motor 101 drives the drive gear 102 to make the main sliding spring 104 fixed on the transmission rack 103 displace, so that the relative length of the main sliding spring 104 and the fixed spring 106 changes, the main sliding spring 10 is longer, the fixed spring 106 is unchanged, which causes the bending of the whole structure to drive the finger joint; the straightening action of the finger joint is that the reverse opening DC motor 101 is opened, the main sliding spring 104 fixed on the transmission rack 103 is displaced, so that the length of the main sliding spring 104 and the fixed spring 106 is equal, which causes the straightening of the whole structure to drive the finger joint; the finger sleeve ring 107 is monitored by a plurality of force sensors 6, which respectively monitor the stress of each part of the finger, and the signals are transmitted to the controller 2, and the running state of the DC motor 101 is controlled by the controller 2; after the power is turned on, the controller 2 monitors the stress of each part of each finger, analyzes the intention of the patient to bend or straighten the finger joint through algorithm, and then controls the motor to straighten or bend the joint. The stress of the finger is continuously monitored during the operation, the stiffness of the finger is judged through algorithm, so as to adjust the bending and straightening range of the finger; the data of the force sensor 6 is received and analyzed, the bending movement speed, amplitude, time length and other parameters adopted in this treatment are output, and the rehabilitation movement is completed.
