Detailed ways

The recovery device after knee replacement surgery of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the recovery device after knee arthroplasty of the present utility model has a structure consisting of a base 1 and a movable plate 2, one end of the movable plate 2 and one end of the base 1 Hinged by the first rotating shaft 5, the base 1 is provided with a groove 11, the telescopic support rod 8 is movably connected in the groove 11, and the bottom of the free end of the movable plate 2 is provided with a fixed plate 22 with a slot , the top of the telescopic support rod 8 is movably inserted into the groove on the fixed plate 22; the top surface of the movable plate 2 is provided with a thigh placing plate 3 and a calf placing plate 4, and one end of the thigh placing plate It is hinged with the movable plate 2 through the second rotating shaft 7, and the other end of the thigh placing plate 3 is hinged with one end of the calf placing plate 4. The bottom of the other end of the calf placing plate 4 is provided with a pulley 41, and the pulley 41 is connected with the movable plate. The chute 21 on the plate 2 is slidingly connected, and one side of the movable plate is provided with a plurality of threaded holes 13, and the free end of the fastening bolt 9 passes through the threaded holes 13 and leans against the side wall of the pulley; One end of the board 4 is provided with a pedal board 10 .

The telescopic support rod 8 is composed of a cavity plate and an adjustment plate 84, the adjustment plate 84 is nested with the cavity plate 81, and the bottom of the cavity plate 81 is hinged with one end of the groove on the base through the rotating shaft 83, and the An adjustment bolt 82 is provided on one side of the cavity plate, and the adjustment bolt passes through the cavity plate 81 and abuts against the side wall of the adjustment plate 84 .

A spring 6 is arranged between the bottoms of the thigh placement board 3 and the calf placement board 4. After the patient places the affected leg on the thigh placement board and the calf placement board, the pedal board can slide back and forth, and the stretching force of the spring urges the patient's leg , to achieve the purpose of exercise.
