Knee joint adhesion lysis device

The invention relates to the technical field of medical instruments, in particular to a knee joint adhesion lysis device. The knee joint adhesion lysis device comprises a seat, shank supporting structures, first driving apparatuses and a second driving apparatus, wherein the seat comprises a supporting frame and a cushion pivoted to the supporting frame; each shank supporting structure is locatedin front of the supporting frame; the driving end of each first driving apparatus is connected with the corresponding shank supporting structure so as to drive the corresponding shank supporting structure to move front and back; the driving end of the second driving apparatus is connected with the cushion so as to drive the cushion to rotate; the front-back movement of the shank supporting structures can act on the shanks of the patient to enable the knee joints to slide front and back; and the cushion rotates to act on the thighs of the patient to realize long-axis stretching of the knee joints, so that the basic nor
