Description

Traction equipment for orthopedic treatment and rehabilitation and method thereof

Technical Field

The invention belongs to the technical field of orthopedic rehabilitation medical equipment, and particularly relates to traction equipment for orthopedic treatment and rehabilitation and a method thereof.

Background

The fracture treatment has three major processes: reset, fixation and functional exercise. The most important of which is functional exercise. Many people who have been exposed to orthopedic treatment know that 'three-minute treatment and seven-minute exercise' how important functional exercise is for orthopedic patients.

The ultimate goal of fracture treatment is to restore normal function to the injured site as soon as possible. For the final purpose of restoring function, both the reduction fixation and the surgical treatment are completed only by primary treatment. In order to restore the patient to normal as quickly as possible, various forms of functional exercises must be performed under the guidance of medical personnel, but no other way around.

The functional exercise has the advantages of promoting detumescence and preventing joint adhesion and stiffness. After fracture, soft tissues at the fracture part generally have bleeding and edema with different degrees, and the injured limb has lumps. If the lump is not removed in time, it may cause the corresponding soft tissue to adhere and even become hard. This adhesion can also occur from muscle to tendon, tendon to synovial membrane and within the joints, thereby affecting the function of muscle contraction. Many people after a fracture feel that the joints around the fracture do not move as well as before, and some people even swell and have deformities. This can be avoided by functional exercise.

Secondly, promoting fracture healing. Through functional exercise, injured limb muscle is subjected to repeated relaxing and contracting activities, so that the longitudinal extrusion force of fracture can be strengthened, the fracture gap is reduced, the fracture part is more stable, the nutrition of the fracture part can be improved, and the healing of the fracture is promoted. The function exercise can also correct tiny fracture dislocation and is also beneficial to the healing of the fracture.

Thirdly, the thrombosis can be prevented. For a fracture patient lying in bed for a long time, because muscles do not move in a relaxing way, the blood circulation can be slowed down, and thrombus is easily formed when blood slowly flows in damaged blood vessels. Small thrombi can dissolve by themselves, and if the thrombi are large, they fall off from the vascular wall and enter the systemic circulation along with the blood, which can cause the infarction of important organs such as heart, brain, lung, etc., even cause sudden death. And through functional exercise, the elasticity of the vessel wall around the injury can be enhanced, the blood circulation is smooth, and the thrombosis is prevented.

The existing traction equipment can not provide support for patient rehabilitation training, and economic cost is increased by singly carrying out rehabilitation training, so that some patients can carry out walking training by assisting nursing personnel, but the nursing personnel carelessly carry out walking training, so that wound recurrence of the patients can be caused, and serious consequences are caused; moreover, the existing rehabilitation training device has a single function, cannot provide assistance support for the rehabilitation training device, cannot exert force on the patient in early rehabilitation training, and is not beneficial to rehabilitation training of the patient.
