Description

Technical Field

[0001] The utility model belongs to the technical field of orthopedic treatment, and specifically relates to a novel multifunctional auxiliary traction device. Background Art

[0002] Multifunctional assisted traction devices are widely used in rehabilitation and physical therapy, particularly for traction treatment of the spine, cervical spine, and limbs, where they are crucial tools for restoring normal patient function. Traditional traction devices are often manually adjusted, which is cumbersome and lacks precision. This can easily lead to asymmetry during traction, thus compromising treatment effectiveness. With the advancement of rehabilitation technology and increasing patient comfort requirements, the market demand for traction devices with higher precision, improved synchronization, and automated adjustment capabilities is becoming increasingly urgent.

[0003] Patent document CN214128960U discloses an "orthopedic traction device" comprising a "bed frame and vertical, horizontal, and sliding frames on a bed frame forming a rectangular frame structure. A slide bar is provided between the two slides, and a pulley is provided on the slide bar. A through-hole is provided at the bottom end of the right vertical frame. The rotating rod is connected to the through-hole bearing. The outer end of the rotating rod is provided with an integrally formed turntable. A sling is provided on the pulley. A sling is fixedly connected to the connecting ring of the sling and passes through the two pulleys and the rope hole of the rotating rod in sequence for fixed connection."

[0004] The above-mentioned device uses winches on both sides of the bedside, uses a rotating rod to adjust the length of the traction rope, and rotates the turntables on both sides to achieve limb traction. It can be operated independently, and the technical means of adjusting the traction position and angle of the sling is facilitated by the movement of the slide bar in the groove and the movement of the pulley on the slide. However, there are still some shortcomings when using the above-mentioned device. First, the adjustment of the traction device often relies on manual operation, and it is difficult to achieve synchronous adjustment of the traction devices on both sides, resulting in insufficient symmetry and balance during the traction process, affecting the treatment effect. Secondly, when adjusting the height, the existing equipment is usually unable to flexibly adjust according to the patient's body shape, which may cause the patient to feel uncomfortable during the traction process, thereby reducing the effect and comfort of the treatment. In addition, manual adjustment is prone to errors and cannot respond to the patient's discomfort in a timely manner, increasing the risk of secondary injury and reducing the safety of treatment. Therefore, there is an urgent need for a multifunctional auxiliary traction device that can automatically adjust, ensure traction symmetry and improve patient comfort to improve the treatment effect and safety.
