Description

Rehabilitation training device for upper limb fracture

Technical Field

The invention particularly relates to a rehabilitation training device for upper limb fracture.

Background

Fracture refers to the complete destruction or continuous interruption of bones, and when the strength borne by the bones exceeds the maximum strength which can be borne by the bones, the fractures occur, and most patients can recover the original functions after timely and proper treatment. The treatment of fracture includes three stages of reduction, fixation and rehabilitation.

Rehabilitation therapy is an important part in fracture treatment, and reasonable functional exercise is actively and actively carried out, so that not only can complications be prevented, but also the functions of affected limbs can be recovered as early as possible. The rehabilitation form of the upper limb in the middle and later stages of fracture should gradually move the upper and lower joints of the fracture with the help of medical care personnel, and gradually increase the number, amplitude and strength of the movement. In the prior art, the patient can hardly move the affected limb with the other hand, so that the joint movement can be only assisted by medical staff.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the rehabilitation training device for the fracture of the upper limb, which can help the patient to move the joint of the affected limb and improve the convenience.

In order to achieve the purpose, the invention is realized by the following technical scheme: a rehabilitation training device for upper limb fracture comprises a fixed frame;

the two driving parts are symmetrically arranged on the fixed frame and comprise screw rods and sliding seats, one ends of the screw rods are rotatably connected with the fixed frame, the two screw rods are parallel and arranged towards the same direction, and the sliding seats are in threaded connection with the screw rods;

the clamping part is arranged between the two driving parts and comprises a clamping sleeve, a universal ball and a telescopic rod, the telescopic rods are arranged at two ends of the clamping sleeve, and one end of each telescopic rod, which is far away from the clamping sleeve, is connected with the sliding seat through the universal ball; and

and the rotating shaft can be detachably connected with the other end of the screw rod.

Move the mount to patient's body, put into the cover that presss from both sides with the upper limbs that need rehabilitation training to be connected the rotation axis with one of them lead screw, the patient rotates the rotation axis through another hand, drives the lead screw and rotates, thereby makes the sliding seat remove, and the sliding seat passes through the telescopic link and drives the cover that presss from both sides and remove and rotate, thereby lets the upper limbs accomplish the joint activity of bent elbow.

The rehabilitation training device for the fracture of the upper limb has the beneficial effects that: under the condition that does not have medical personnel, can let the patient move about by oneself and suffer from the joint of limb, promoted the convenience to can guarantee security and travelling comfort better through oneself control.
