Device for rehabilitating functions of elbow joint of upper limb after operation

Abstract

The invention discloses a device for rehabilitating functions of an elbow joint of an upper limb after an operation. The device is characterized by comprising an elbow joint bushing, upper arm bone positioning plates, front arm bone positioning plates, a hinge shaft, a function rehabilitator, a longitudinal connecting fabric strap, a transverse connecting fabric strap, positioning airbags, air tubes and an air valve, wherein at least four upper arm bone positioning plates are fixedly arranged on the outer periphery of the upper half part of the elbow joint bushing; at least four front arm bone positioning plates are fixedly arranged on the outer periphery of the lower half part of the elbow joint bushing; the function rehabilitator is arranged on the lateral surface of the elbow joint bushing; and the positioning airbags are arranged between the upper arm bone positioning plates and the elbow joint bushing as well as between the front arm bone positioning plates and the elbow joint bushing respectively, and are communicated with the air valve through the air tubes. Due to the adoption of the structure, the device has the advantages of novel structure, simplicity in use, convenience for operation, high function rehabilitation speed, active exercises, combination of fixation and rehabilitation, and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an elbow joint function recovery device after upper limb surgery. Background technique [0002] Elbow stiffness and limited range of motion are common complications following elbow trauma or surgery. Soft tissue is the main cause of elbow stiffness. Orthoses use the principle of creep or stress relaxation to increase the passive range of motion (ROM) of the joint, and play an important role in the rehabilitation of post-traumatic elbow dysfunction. Orthotics should follow basic design and application principles. Clinical experience and research have shown that through reasonable design and application, orthoses can effectively improve the ROM of post-traumatic elbow stiffness.

[0003] Disadvantages of traditional rehabilitation equipment: 1 Traditional rehabilitation machines are designed to prevent elbow joint adhesions by passively moving the elbow joint

However, in the early stage (within one week) after complicated elbow joint surgery, too much activity can easily cause hemorrhage in the elbow joint to not be well absorbed, and the incision cannot heal on schedule, which increases the stress at the fracture site and affects the early formation of original callus; In clinical practice, it is found that the final extension of the elbow joint is difficult to correct, and rehabilitation machines are required to provide overcorrection training for the elbow joint. The range of motion that traditional rehabilitation equipment can provide is 0-140, which is within the normal range of motion of the elbow joint and cannot effectively offset the anterior elbow joint. Resisting force due to lateral soft tissue contracture, leaving a loss of elbow range of motion
