The camera 40 is used to capture the movement of the target hand, wherein the target hand is a healthy side hand, for example, if the left hand has dyskinesia (i.e. the left hand is an affected side hand), the right hand is a healthy side hand and is used as the target hand. The display 50 may be positioned above or on top of the housing 10, specifically, the patient sees an image of the healthy hand and a mirror image thereof from the display 50. The specific mirror image implementation manner may be to embed a mirror image module in the display 50, so as to perform mirror image processing on the moving image of the healthy hand collected by the camera 40 by using the mirror image module and display the moving image on the display 50 together, or to implement a mirror image function on the image by using the display 50 with the mirror image function.

By mirroring the motion image of the healthy side hand, the patient is enabled to observe not only the motion of the healthy side hand from the display 50, but also the mirror-simulated motion of the affected side hand from the image displayed on the display 50. Thus, for a patient with motor dysfunction in the left hand, the mirror-image movement of the hands is observed from the display 50, thereby giving the patient the illusion that the left hand can move, and subjectively driving the patient's brain to participate in left-hand rehabilitation.

In the process, the vibration stimulation module, the electrical stimulation module, the temperature stimulation module, the acousto-optic stimulation module and other structures can be matched to perform multi-mode senses such as vibration sense, electric shock, temperature sense, vision and auditory sense, so that active participation of the brain in rehabilitation training can be adjusted through body sense signals, and therefore the rehabilitation effect of the finger movement function after cerebral apoplexy or damage of a single hand is effectively improved, and the effect of rehabilitation treatment on a patient is improved. It should be noted that the arrangement positions of the structures such as the vibration stimulation module, the electrical stimulation module, the temperature stimulation module, the acousto-optic stimulation module and the like have various possibilities, and the following description will be made at suitable positions, which are not described herein again.

In some embodiments, as shown in fig. 1 and 2, the hand function mirror image treatment apparatus 100 further includes a first bracket 101 and a second bracket 102 connected to the housing 10, wherein the first bracket 101 and the second bracket 102 are respectively disposed corresponding to the first opening 12a and the second opening 12b to support the left arm and the right arm, respectively, so as to improve the comfort during rehabilitation training.

Further, the first bracket 101 and/or the second bracket 102 are provided with at least one of a vibration stimulation module, an electrical stimulation module, a temperature stimulation module and an acousto-optic stimulation module, so that the active participation of the brain in rehabilitation training is mobilized when mirror image treatment is performed, and the rehabilitation training effect is improved. For example, as shown in fig. 4, taking temperature stimulation as an example, the first bracket 101 and the second bracket 102 are provided with the temperature module 60 and the heat conducting member 60a, and the heat conducting member 60a is used for conducting heat generated by the temperature module 60 to corresponding bearing surfaces of the first bracket 101 and the second bracket 102, so as to perform temperature stimulation on wrists placed on the first bracket 101 and the second bracket 102, thereby implementing temperature sensing training.

In some embodiments, the adjustment mechanism 30 may be adjusted either electrically or manually, or a combination of the two.

Thus, the lead screw 32 can be rotated by rotating the hand wheel 33, so that the lead screw 32 drives the training mechanism 20 to slide relative to the base plate 10 a. Specifically, in this embodiment, when the hand wheel 33 rotates the screw rod 32, the screw rod 32 drives the training mechanism 20 to move close to or away from the side of the shielding member 12 where the first opening 12a and the second opening 12b are provided. It will be appreciated that when the adjustment mechanism 30 is of the electrically-actuated adjustment type, the hand wheel 33 may be replaced by a motor or the like.

Both ends of the screw rod 32 are connected to the base plate 10a through a support base, respectively. Specifically, the base plate 10a is connected with a first supporting seat 32a and a second supporting seat 32b, the first supporting seat 32a and the second supporting seat 32b are arranged at intervals along the screw rod 32, one end of the screw rod 32 is rotatably connected with the first supporting seat 32a, and the other end of the screw rod 32 is rotatably connected with the second supporting seat 32 b. Further, the first supporting seat 32a and the second supporting seat 32b are provided with bearings, and the screw rod 32 is rotatably connected with the first supporting seat 32a and the second supporting seat 32b through the corresponding bearings, so as to improve the smoothness of rotation of the screw rod 32 by using the bearings. The first supporting seat 32a and the second supporting seat 32b may be connected to the bottom plate 10a by welding or snap-fit connection, or may be connected to the bottom plate 10a by a connecting member such as a screw or a bolt.

In some embodiments, the adjustment mechanism 30 includes a connecting base 34, as shown in fig. 5, the connecting base 34 has a first connecting portion 34a, a second connecting portion 34b and a threaded connecting portion 34c connected, the first connecting portion 34a is connected with the first sliding member 31, the second connecting portion 34b is connected with the training mechanism 20, and the threaded connecting portion 34c is threaded with the screw 32. When the position of the training mechanism 20 in the box 10 needs to be adjusted, the hand wheel 33 is only required to be operated to drive the screw rod 32 to rotate, the screw rod 32 drives the threaded connection portion 34c to move, so that the connection seat 34 slides relative to the bottom plate 10a, and then the training mechanism 20 is driven by the connection seat 34 to move relative to the bottom plate 10 a.

Further, in some embodiments, the first sliding assembly 31 includes a first sliding rail 311 and a first sliding block 312, as shown in fig. 5, the first sliding rail 311 is fixed to the bottom plate 10a, the first sliding block 312 is slidably connected to the first sliding rail 311, and the connecting seat 34 is fixed to the first sliding block 312, so that the connecting seat 34 is slidably connected to the bottom plate 10a, so that when the screw rod 32 rotates, the screw rod 32 drives the connecting seat 34 to slide along the first sliding rail 311, so that the training mechanism 20 connected to the connecting seat 34 moves relative to the bottom plate 10a, and then the training mechanism 20 is driven by the connecting seat 34 to move to or away from the gripping training position.

The concrete implementer may also set the connection relationship between the components according to the installation requirement, for example, the first slide rail 311 and the bottom plate 10a may be connected by bolts. The connecting seat 34 and the first sliding block 312 may be connected by a bolt, or may be fixed relatively by welding.

It should be noted that the number of the first sliding assemblies 31 may be 1 group, or 2 groups or more than 2 groups, and when the training mechanism 20 is slidably connected to the bottom plate 10a through 2 groups or more than 2 groups of the first sliding assemblies 31, the stability of the sliding connection between the training mechanism 20 and the bottom plate 10a is improved, so as to improve the smoothness of the position adjustment of the training mechanism 20. In this embodiment, the screw rod 32 only needs to be connected to the connecting seat 34 corresponding to one set of the first sliding assemblies 31, and can drive the training mechanism 20 to slide relative to the bottom plate 10 a. Preferably, as shown in fig. 6, the screw rod 32 is disposed corresponding to the first sliding component 31 located in the middle of the first sliding components 31, so that when the screw rod 32 drives the training mechanism 20 to move relative to the bottom plate 10a, the training mechanism 20 can smoothly slide relative to the bottom plate 10a, and the phenomenon of clamping caused by the deviation of the stress to one side does not occur.

As shown in fig. 7, the training mechanism 20 includes a support rod 21, a grip rod 22 and an elastic member 23, the support rod 21 is disposed parallel to the grip rod 22, the grip rod 22 is used for being gripped by fingers and moving towards the support rod 21 under the grip force of the fingers, the elastic member 23 is connected to the grip rod 22, and the elastic member 23 is configured to make the grip rod 22 have a tendency to move away from the support rod 21. Like this, the patient only needs the finger to grip on bracing piece 21 and grab bar 22 when the gripping training, and the finger is buckled and is made grab bar 22 move repeatedly can relative bracing piece 21. Understandably, in the process, when the healthy hand drives the grasping rod 22 to approach the supporting rod 21, the affected hand grasping the grasping rod 22 will move along with the healthy hand. The grasping rod 22 is loosened by the side-caring hand, the grasping rod 22 is far away from the support rod 21 under the action of the elastic force of the elastic piece 23, so that the fingers of the hand at the affected side are driven to be passively opened, the patient obtains the feeling that the hand at the affected side can grasp, and the grasping function of the hand at the affected side is gradually recovered.

Further, at least one of a vibration stimulation module, an electrical stimulation module, a temperature stimulation module and an acousto-optic stimulation module is arranged in the grabbing rod 22, so that the active participation degree of the brain in rehabilitation training is mobilized when mirror image treatment is carried out, and the rehabilitation training effect is improved.

With reference to fig. 7 and 8, the training mechanism 20 includes a displacement detecting assembly 24, and the displacement detecting assembly 24 is used to detect the relative displacement between the grasping rod 22 and the supporting rod 21, so that the finger flexion displacement of the healthy lateral hand and the finger flexion displacement of the affected lateral hand can be conveniently known, so as to provide a reference for the rehabilitation condition of the affected lateral hand. Specifically, the user grasps the healthy lateral hand alone, and obtains the finger flexion displacement of the healthy lateral hand by using the displacement detection assembly 24; accordingly, the patient's hand is grasped solely, and the finger flexion displacement with the patient's hand is obtained using the displacement sensing assembly 24. The difference of the gripping functions of the two hands can be known through the buckling displacement of the fingers of the two hands, and reference is provided for the rehabilitation training effect. Understandably, the closer the finger flexion displacement of the affected hand is to that of the healthy hand, the closer the grasping function of the affected hand is to the function during rehabilitation.

In some embodiments, the display 50 is used to display a guiding gesture and/or a virtual scene, for example, the display 50 first displays an image of a gesture to be made next by the guiding patient, and then captures or displays a moving image and a mirror image of the side-healthy hand; alternatively, the display 50 collects or displays the moving image and the mirror image of the side-care hand, and simultaneously displays the gesture image to be made next by the patient; or, in order to increase the interest of the training process, the corresponding virtual scenes can be displayed in a matching manner while the gripping training or other training is carried out, so that the patient is stimulated to continuously input the rehabilitation training and the participation degree of the brain of the patient on the motion of the affected hand is improved, for example, the display can display the virtual scenes such as playing piano, fist making match, tug-of-war match, painting and the like, the patient is guided to play games, the rehabilitation training is interesting, and the hand function is helped to be recovered.

In some embodiments, the displacement detection assembly 24 may be configured to perform displacement detection by way of photodetection.
