Problems solved by technology

[0004] The Chinese patent application whose publication number is CN103735389B discloses a coordination training rehabilitation device between fingers. It has played a certain role, but there are still some problems: (1) the above two devices are driven by motors, and the stability and safety are poor. Once a fault occurs, it is easy to cause secondary damage to the fingers; (2) the above two devices This kind of device does not carry out rehabilitation training to all fingers of people, but only carries out rehabilitation training to one or three fingers, and the training effect is not sufficient

Embodiment Construction

[0046] Embodiments of the invention include:

[0047] Such as figure 1 As shown, a shape memory alloy-driven rope traction finger rehabilitation training device includes a vertically arranged frame 1, a fixed platform 15 for supporting the palm, a finger driving mechanism, a finger rehabilitation training mechanism, and a sensing and control system. Wherein: the frame 1 is fixed on the worktable, the fixed platform 15 is used to support the palm, and the place where the fixed platform 15 places the thumb has a hollowed out rectangular groove to prevent from hindering the thumb rehabilitation training.

[0048] Such as figure 1 and as figure 2 As shown, the finger driving mechanism includes a pulley 13, a steel wire rope 5, a shape memory alloy wire 11, and a shape memory alloy spring 12. The pulley 13 is installed on the rotating shaft 14, the steel wire rope 5 goes around the groove of the pulley 13, one end of the shape memory alloy wire 11 is connected to the steel wire...

Abstract

The invention discloses a shape memory alloy driven rope pulling type finger rehabilitation training device and method. The device comprises a vertically-arranged frame, a fixing platform is arranged in the frame, a first pulley, a third pulley and a guiding ring are arranged on the top inside the frame, five second pulleys are arranged at the bottom inside the frame, and a rotating shaft is rotationally installed inside the frame; the device further comprises fingerstalls arranged on the five fingers of the palm in a sleeving mode, an upper steel wire rope connected with the fingerstalls is wound around the first pulley and the third pulley and then penetrates through the guiding ring to be fixed to the rotating shaft, and a lower steel wire rope connected with the fingerstalls is wound around the second pulleys and then is fixed to the middle of the rotating shaft; a magneto-rheological damper and a belt pulley are arranged on one side of the frame, the magneto-rheological damper is connected with the rotating shaft through an internal rotor, the rotating shaft is connected with the belt pulley through a key, a steel wire rope is wound around the belt pulley, and the two ends of the steel wire rope are connected with the bottom of the frame through shape memory alloy wires and springs. The method is applicable to five-finger active / passive coordinated rehabilitation training of a finger hemiplegic patient or a finger injured patient.

Description

technical field [0001] The invention relates to the field of finger rehabilitation training devices, in particular to a shape memory alloy driven rope traction finger rehabilitation training device and method. Background technique [0002] With the aging of the population in our country, the number of patients with diseases such as stroke and hemiplegia is gradually increasing. Such diseases can lead to hand muscle atrophy. If not treated in time, it will affect the use of finger functions. When workers are engaged in various operations, they need their fingers to grab things frequently. If something unexpected happens, it will cause damage to their fingers. Fingers are an important part of the human body. Once damaged, it will have a great impact on life and work, thus bringing a burden to the family and society. [0003] In the traditional finger rehabilitation training, most of the doctors are one-on-one counseling patients for rehabilitation training. This kind of rehab...
