[0004] The inventor discovered the following defects during the operation of the specific embodiment: In the actual process of head and face surgery, different angles are required to be used to operate on the patient's face, but the existing equipment can only adjust the angle of the head alone, which may easily cause the fixed head to become loose and affect the subsequent surgical accuracy. In addition, the existing equipment is fixed on the bottom plate of the back of the head by covering the face with a net. After a long operation, it is easy to cause long-term compression of the back of the patient's head and cause discomfort. Summary of the invention

[0005] 1. Technical problems to be solved by the invention: The present invention provides a head positioning device for cosmetic surgery, which is used to solve the technical problems existing in the above-mentioned background technology.

[0006] 2. Technical solution: To achieve the above-mentioned purpose, the technical solution provided by the present invention is: a head positioning device for cosmetic surgery, comprising a bed frame, a universal wheel is movably connected to the lower surface of the bed frame, equipment mounting frames are arranged on both side surfaces of the bed frame, a lifting mechanism is arranged on the upper surface of the bed frame, a plurality of supporting legs are fixedly connected to the upper surface of the bed frame, a fixed bed board is arranged above the supporting legs, a movable bed board is movably connected to one side of the fixed bed board, and a head fixing mechanism is arranged on the upper surface of the movable bed board.

[0007] Furthermore, the movable bed board and the fixed bed board only have connecting parts, and the movable bed board forms a swing structure above the bed body support through the lifting mechanism below it. The upper surfaces of the movable bed board and the fixed bed board are provided with ventilation holes, and the head fixing mechanism follows the movement of the movable bed board.

[0008] Furthermore, the lifting mechanism includes a rotating shaft base, one side of the rotating shaft base is movably connected to a rotating shaft, the surface of the rotating shaft is fixedly connected to a pulling handle, the surface of the pulling handle is sleeved with a rotating rod, the top of the rotating rod is fixedly connected to a limiting plate, and the other end surface of the rotating shaft is fixedly connected to a rotating bracket.

[0009] Furthermore, the rotating pull rod is threadedly connected to the surface of the bed body bracket, and a rotating handle is provided at the other end of the rotating pull rod. The pulling handle drives the rotating shaft and the rotating bracket to rotate on the surface of the rotating shaft base through the rotation of the rotating pull rod, and the rotating bracket drives the movable bed board to swing on the side of the fixed bed board.

[0010] Furthermore, the head fixing mechanism includes an I-shaped bracket, the inner surface of the bracket is fixedly connected with a sliding positioning rod, two sliding positioning rods are arranged on one side of the sliding positioning rod, and a net pulling clamp is slidably connected to the surface of the sliding positioning rod, a rotating top shaft is arranged on the upper end surface of the net pulling clamp, a fastening screw is arranged on the surface of the net pulling clamp, two I-shaped brackets are arranged, and a connecting curved plate is fixedly connected to each other, a sliding hole is arranged on the surface of the connecting curved plate, a telescopic shaft is slidably connected to the surface of the movable hole, a pushing plate is arranged on one side of the telescopic shaft, and an auxiliary supporting curved plate is arranged on one side of the pushing plate.

[0011] Furthermore, two mesh-pulling clamps are arranged on the surface of the sliding positioning rod, and rotating top shafts are arranged on the upper and lower end surfaces of the mesh-pulling clamps. The two mesh-pulling clamps form a vertical sliding structure on the surface of the sliding positioning rod through the rotating top shafts at both ends.

[0012] Furthermore, the mesh-pulling splint is composed of two supporting plates, which are fixedly connected by fastening screws, and a fixed net that fits the surface is arranged between the mesh-pulling splints, and a fixed net that fits the back of the head is installed on the surface of the lower end of the mesh-pulling splint.

[0013] Furthermore, the push plate and the auxiliary support curved plate form a sliding structure on the surface of the sliding hole through a telescopic shaft.

[0014] 3. Beneficial effects: The present invention has a reasonable design. When performing facial plastic surgery, the facial fixing mesh and the mesh at the back of the head are installed on the patient's face and back of the head by tightening screws on the surfaces of the two mesh clamps in the head fixing mechanism. The two rotating top shafts are rotated to drive the facial fixing mesh and the mesh at the back of the head to be fixed on the patient's head for preliminary fixation. The two mesh clamps can be driven to a comfortable position for the patient by adjusting the rotating top shaft. At the same time, the push plate is moved along the sliding hole to move the auxiliary support curved plate on one side of the push plate to the bottom of the patient's head to provide auxiliary support for the patient's head and prevent the patient's head from falling under gravity. In this way, the patient's head is evenly fixed by the two meshes, rather than having a single mesh fixed in a single direction, to prevent the patient's head from being pressed for a long time and causing discomfort. When the angle of the patient's head needs to be adjusted during the operation, the rotating pull rod is adjusted so that the limit plate at one end of the rotating pull rod drives the pulling handle to move, thereby driving the rotating shaft and the rotating bracket on its surface to rotate, so that the rotating bracket drives the overall angle of the head fixing mechanism to rotate, thereby adjusting the angle of the patient's face during the operation. Since the patient's upper body is moved as a whole during the rotation process, loosening of the head fixation caused by a single movement is avoided. BRIEF DESCRIPTION OF THE DRAWINGS
