Description

Sports Medicine Joint Postoperative Rehabilitation Training Device

technical field

The utility model belongs to the field of medical equipment, in particular to a rehabilitation training device for sports medicine joint surgery.

Background technique

The knee joint is composed of the medial and lateral condyles of the femur, the medial and lateral condyles of the tibia, and the patella. It is the largest joint in the human body with the most complex structure and more opportunities for injury. It belongs to the pulley joint.

The knee joint is a relatively vulnerable part of the human body. Complications often occur after femoral shaft fractures and knee joint surgery, such as quadriceps muscle adhesion, knee joint stiffness, and difficulty in knee flexion. Severe cases often require secondary surgery Perform quadriceps muscle shaping and knee joint release. The best way to prevent it is to perform knee joint function rehabilitation exercises to promote blood circulation in the knee joint. At present, medical staff generally help patients to move the knee joint manually. Medical staff need to drag the patient's calf for a long time, which will cause fatigue of medical staff and increase the work intensity of medical staff. However, the existing knee joint rehabilitation training device has a complex structure. Expensive, so a knee joint rehabilitation training device is needed to solve the above problems.

Detailed ways

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

Embodiment one

As shown in Figures 1 to 8, a rehabilitation training device after joint surgery in sports medicine includes a first connecting rod 1, a second connecting rod 2, a third connecting rod 3 for placing the calf, and a fourth connecting rod for placing the thigh. The connecting rod 4 and the support plate 5 in a stepped structure, the bottom of the support plate 5 is welded with a leg 6, the left end of the support plate 5 is low and the right end is high,

The left side upper surface of support plate 5 is fixedly installed with motor 7, and the bottom of motor 7 is equipped with damping pad, in the working process of motor 7, plays shock absorption effect, and the control switch of described motor 7 is installed on the support plate. The right end is convenient for the patient to manipulate, and the right side of the motor 7 is fixed with

"T"-shaped column 8, the upper end of the "T"-shaped column 8 is slidingly connected with a moving block 9, the output end of the motor 7 is fixedly connected with the first connecting rod 1, and the output shaft of the specific motor 7 is processed with a keyway, The end of the first connecting rod 1 connected to the motor is processed with a shaft hole, and a keyway is processed in the shaft hole. The first connecting rod 1 is fixedly installed on the output shaft of the lower level 7 through the cooperation of the key and the keyway. Rotate together, one end of the first connecting rod 8 away from the motor 7 is hinged to the second connecting rod 2, and the end of the second connecting rod 2 away from the first connecting rod 1 is rotating and hinged to the moving block 9, the moving The top of the block 9 is welded with a first hinged seat 10, and a rotating shaft is installed on the first hinged seat 10. The third connecting rod 3 is rotatably sleeved on the rotating shaft and is hinged with the moving block 9. The third connecting rod 3 One end away from the moving block 9 is rotatably hinged with a fourth connecting rod 4 , and the end of the fourth connecting rod 4 away from the third connecting rod 3 is rotatably hinged on the second hinge seat 11 welded on the upper surface of the support plate 4 , The third connecting rod 3 and the fourth connecting rod 4 are long plate structures, which are convenient for the placement of the thigh and the calf, while the third connecting rod 3 and the fourth connecting rod 4 are arranged on the central axis of the support plate 5, so that the patient When the left leg needs to be trained, the human body should lie on the side of the right leg.
