Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an ankle traction device and system with adjustable function. Background Technology

[0002] In the field of medical rehabilitation, the treatment and rehabilitation of ankle injuries or diseases typically require immobilization, support, and traction of the ankle joint to promote recovery and alleviate pain. Traditional ankle joint treatment methods often employ relatively simple immobilization devices. While these devices can meet the immobilization needs to some extent, they have significant shortcomings in terms of adjustability, comfort, and precision.

[0003] Specifically, the fixation devices used during and after surgery often lack flexible adjustment capabilities, making it impossible to fine-tune them according to individual patient differences and recovery progress. This not only affects treatment outcomes but may also cause secondary injuries to patients due to inappropriate fixation methods. Furthermore, these fixation devices typically cannot accurately record and adjust traction distances, making it difficult for doctors and patients to quantitatively assess rehabilitation effects, thus hindering the development and adjustment of subsequent treatment plans. Utility Model Content

[0007] Furthermore, the first adjustment mechanism also includes an adjustment scale; the adjustment scale is arranged on the side wall of the adjustment slide along the axial direction of the adjustment slide.

At this time, the inner cylinder can move along the axial direction of the outer cylinder, and the arc-shaped support plate can move along the length direction of the bed under the drive of the inner cylinder, so as to adjust the distance between the arc-shaped support plate and the support frame of the bed. When the inner cylinder moves to the designated position, the second limiting bolt is threaded into the second limiting screw hole and the corresponding third limiting screw hole, and the distance between the arc-shaped support plate and the support frame of the bed is fixed. At this time, the arc-shaped support plate can support the patient's ankle joint.

[0018] 6.
