Description

A kind of rehabilitation training device after knee surgery

Technical field

The utility model relates to the technical field of training devices, and in particular to a rehabilitation training device after knee surgery.

Background technique

There are many kinds of rehabilitation training equipment after knee surgery, but most of them perform corresponding knee bending exercises and knee joint straightening exercises for the knee joint and related muscle groups. Among them, knee bending exercises rely on imported or domestic passive rehabilitation training equipment. Knee joint rehabilitation training equipment is currently a special equipment for knee joint rehabilitation training in hospitals and is also an important means of postoperative rehabilitation. This passive rehabilitation training device is driven by a motor, and its two moving arms carry the patient's thigh and calf respectively. When in use, the patient places his legs completely on the rehabilitation training device. The motor drives the power arms to move, and the movement trajectory simulates the human body. Leg bending action. However, this type of equipment is expensive, has only one function, is bulky, and is very heavy. Patients usually rent it for use in hospitals. Most patients have no intention or ability to purchase it personally. However, after the patient is discharged from the hospital, rehabilitation training of the knee joint is still required. Continuing, it is very troublesome to rely solely on the patient's family members for help in training, and the family members' care is not standardized, which cannot achieve a good training effect. It may prevent the patient from fully recovering and leave sequelae.

In the patent with publication number CN211705216U, a knee joint rehabilitation device is proposed, which includes a base plate, a seat is fixedly connected to the left side of the top of the base plate, and a driving frame is fixedly connected to the right side of the top of the base plate. A speed regulating motor is fixedly connected to the inner cavity of the frame, a rotating rod is fixedly connected to the output end of the speed regulating motor, and a first bearing is movably connected to the side of the rotating rod away from the speed regulating motor. The utility model can make the device through a base plate, a seat, a driving frame, a disc, a rotating rod, a speed regulating motor, a movable sleeve, a fixed rod, an output rod, a transmission chain, a driving gear, a driven gear, a pedal and a movable rod. Achieving the function of good use effect solves the problem that the existing knee joint rehabilitation devices on the market do not have the function of good use effect. The elderly cannot control the training rhythm by themselves during the training process. At the same time, the knee joint is also stressed during the training process and cannot be operated properly. It is easy to be counterproductive and not conducive to the rapid recovery of the elderly.

In the above-mentioned patents, patients can perform knee joint rehabilitation training through seats and pedals. Since different patients have different damaged surfaces of knee joints, the bending angle of the knee joints needs to be adjusted during rehabilitation training. The above patents cannot adjust the knee joints. The bending angle affects the patient's rehabilitation training effect.
