The invention discloses an operation bed with multiple shapes and belongs to the technical field of medical device application. A bed plate is divided into an upper bed plate, a left bed plate and a right bed plate. When the left bed plate and the right bed plate are closed, the left bed plate and the right bed plate are mutually spliced to form a plane. When the upper bed plate is in the horizontal position, a patient is capable of lying on the operation bed to undergo an operation. When the upper bed plate is in the oblique position, the patient is capable of sitting on the operation bed toreceive treatment and examinations on upper limbs or the head, so the operation bed is capable of being suitable for all kinds of comfort poses of the patient. When the upper bed plate is in the oblique position, the left bed plate and the right bed plate are opened, and lower limb supports are rotated to be perpendicular to the bed body, so legs of the patient can be fixed on the lower limb supports, and it is quite convenient to carry out foot operations or gynecological operations on the patient. According to the invention, the operation bed is simple in structure and low in manufacturing cost; and meanwhile, different operations can be achieved in different departments by changing shapes; and it is convenient to use the operation bed.
