Description
Technical Field
The utility model relates to a finger rehabilitation device which can adjust the relative angle between a palm correction tool body and a forearm correction tool body in a matching way according to the bending degree of wrist joints of different users.
Background
At present, when the fingers or the wrist of a patient suffering from hand dysfunction due to stroke or head injury cannot exert force autonomously and are bent and difficult to stretch, the patient usually needs to be helped to perform rehabilitation and recover normal functions by a hand trainer.
Therefore, there is an invention of "hand rehabilitation training device" patent No. I541011 issued by taiwan in china at 11/7/2016, which discloses: the hand rehabilitation training device comprises a palm-shaped plate body and a forearm fixing plate which are fixed into a whole to form an included angle, five rods are fixedly arranged on the top surface and the side edge of the palm-shaped plate body, five finger sleeves are respectively sleeved on fingers, each finger sleeve is fixedly provided with one end of a pull rope, each pull rope penetrates through a corresponding rod guide groove structure, all the pull ropes penetrate through a guide sleeve ring, the other ends of all the pull ropes are fixedly arranged on a concentrated sleeve ring, one end of a connecting rope is fixedly arranged on the concentrated sleeve ring, an upper arm fixing plate is provided with a pull rope tightness adjusting assembly, the other end of the connecting rope is fixedly arranged on the pull rope tightness adjusting assembly, an upper arm fixing plate is fixedly arranged on an upper arm, the forearm fixing plate is fixedly arranged on the forearm, the upper arm moves or moves the connecting rope by another hand to.
Since the forearm fixing plate and the palm plate body are fixed into a whole and an included angle smaller than one hundred eighty degrees is formed between the forearm fixing plate and the palm plate body, the included angle is a fixed angle and cannot be adjusted according to the bending angles of wrist joints of different users. In addition, the patent of the former proposal utilizes the pulling handle fixed at the other end of the connecting rope to pull all the pull ropes to be tensed or relaxed, thereby enabling five fingers to generate the action change of stretching, straightening or bending hand rehabilitation training. Because all the pull ropes are pulled at one time to adjust five fingers for rehabilitation, different elastic forces cannot be independently adjusted for different fingers according to the bending degrees of the different fingers, and the use is not ideal.
In addition, there is a new model of "hand dynamic corrector" patent No. M516411 issued by taiwan in china at 1/2/2016, which discloses: the device comprises a corrector plate, wherein finger traction elastic groups are respectively arranged on the corrector plate corresponding to each finger part of a human body, each finger traction elastic group comprises an elastic line, one end of each elastic line is provided with an elastic positioning end for being positioned on the surface of the corrector plate, the other end of each elastic line extends by a set length, and a finger bandage is arranged at the end part of each elastic line; after the correcting tool plate is worn on the hand of a patient, when the fingers sleeved at one end of the finger traction elastic group bend and extend, the elastic positioning end at the other end of the finger traction elastic group is pulled in an elastic state, and corresponding elastic traction is formed by bending and extending of the proximal end joint and the distal end joint of the finger of the patient so as to dynamically rehabilitate the hand.
In the prior art, the orthotic plate comprises a palm area and a wrist area which are integrally extended, wherein the palm area and the wrist area are fixedly integrated and can not be adjusted according to the bending angles of wrist joints of different users. After the patient wears the correcting tool plate, when the finger tied at one end of the elastic line of the finger traction elastic group is bent and stretched, the elastic traction action formed by the elastic coil part at the other end of the finger traction elastic group can be used for rehabilitation, so that the elastic coil part can be installed according to different diseased conditions of the proximal joint and the distal joint of the finger part of the patient, and meanwhile, the elastic coil part (spring) can be used for relatively elastically adjusting better rehabilitation elastic force when the patient carries out various different conditions in the process of hand function treatment training. The spring has relatively large elasticity, so that the spring is not suitable for fine adjustment of a patient who cannot be controlled by fingers, and the fingers of the patient cannot move due to the excessive force of the spring, so that the training and rehabilitation efficacy is difficult to achieve. Moreover, the adjustment of the spring force of the spring is limited, and if the adjustment of a small spring force is required, the spring with a small number of turns and a small wire diameter must be replaced by another spring, so that the disassembly and the replacement are troublesome and time-consuming.
