Description

Knee joint extension and flexion training device

technical field

The utility model relates to the technical field of rehabilitation equipment, in particular to a knee joint extension and flexion training device.

Background technique

Patients with proximal knee fractures or knee ligament injuries need to be immobilized with instruments after conservative treatment or surgery to limit joint activity so that bones or soft tissues can recover normally. After the bone or soft tissue is restored, the immobilization device will be removed, and the patient will have different degrees of knee joint dysfunction, which will affect the patient's walking and knee bending and squatting functions. At present, the treatment methods for this kind of symptoms mostly use release surgery, manual rehabilitation and so on. However, release surgery is a secondary operation, which will cause greater pain to the patient; manual therapy is performed by the therapist, and the duration is short and the treatment cost is high.

Detailed ways

The specific embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can more clearly understand how to practice the utility model. Although the invention has been described in conjunction with preferred specific embodiments thereof, these embodiments are illustrative only and do not limit the scope of the invention.

Referring to FIG. 1 , a knee joint extension and flexion training device includes a base 1 , a support member 2 disposed on the base 1 , a sliding seat assembly, a pulling rope assembly and a control switch.

The support 2 is a board, the support 2 is inclined and fixed to the base 1, the support 2 is used to provide support for the user's feet, and the support 2 is provided near the lower end for fixing the user. First strap on the foot3.

The slide assembly is located on one side of the support 2, the slide assembly includes a slide rail 4, a slide 5, a pulley 6 and a first motor 11, the slide rail 4 is installed on the base 1, and the slide 5 passes through the pulley 6 and the first motor 11. Slide rail 4 cooperates and is installed on slide rail 4, slide seat 5 can slide on slide rail 4 and approach or stay away from support member 2, first motor 11 is installed on slide seat 5 and drives slide seat 5 on slide rail 4 slide.

The pulling rope assembly is located on the other side of the support 2, and the pulling rope assembly includes a second motor 7, a pulling rope 8, a guide wheel 9 and a handle 10, and the second motor 7 and the guide wheel 9 are installed on the base 1, one end of the pull rope 8 is connected to the output shaft of the second motor 7, and the other end of the pull rope 8 is connected to the handle 10 after going around the guide wheel 9.
