This application relates to the field of medical devices and discloses a multifunctional orthopedic surgical saw, including a swing saw body. A saw blade is mounted on the left side of the swing saw body. A fixing ring is disposed on the outer surface of the swing saw body, and two sets of mounting half rings are mounted on the outer surface of the fixing ring. A support block is fixedly mounted on the left side of the mounting half rings. A connecting column is elastically mounted inside the support block. This device uses the pressure generated by the spring on the connecting column, the support frame, and the sealing block to make the sealing block abut against the patient's limb to form a seal. Then, the reciprocating motion generated by the back-and-forth swing of the saw blade drives the synchronous frame and the sliding column to move. The sliding column penetrates into the fitting groove, thereby converting the swing motion of the saw blade into the reciprocating linear motion of the air plate along the inner wall of the sliding groove. This creates a vertical airflow from the air plate towards the exhaust groove in the inner cavity of the placement cavity. Under the guidance of the guide plate, a negative pressure is formed inside the suction port, which finally improves the stability of the swing saw body.
