[0003] In the prior art including the above-mentioned patents, when a patient is lying on an operating table under general anesthesia and undergoing surgery, if the patient's head needs to be turned, auxiliary equipment or manual control is required. Manual control cannot maintain the position for a long time because after the hand is released, the patient's head will return to its original position or deviate slightly, affecting the doctor's operation. When the angle of the patient's head is changed with the help of auxiliary equipment or cushions, the head position cannot be adjusted according to the patient's neck position. In other words, it cannot effectively simulate real head rotation. Long-term incorrect twisting of posture will cause physical discomfort to the patient. Summary of the invention

[0004] The problem to be solved by the present invention is that after a patient under general anesthesia lies flat on an ophthalmic operating table, he or she cannot turn his or her head autonomously during the operation and needs medical staff to assist in the turning or external equipment, which causes inconvenience to the user.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a head fixing bracket for ophthalmic medical surgery, comprising an operating table, a lifting platform is provided at the bottom of the operating table, the lifting platform can control the operating table to move up and down, and a control structure is provided on one side of the top of the operating table; The control structure comprises a base, which is in an arc shape, a slide groove is provided on the top of the base, a roller is provided at the bottom of the inner wall of the slide groove, a movable seat is slidably provided in the slide groove, and an arc plate is provided on the top of the movable seat.

[0006] Preferably, several movable pads are provided on both sides of the top of the arc-shaped plate, a fixed pad is provided on the top of the arc-shaped plate, a rotating plate is rotatably connected between the fixed pad and the movable pad, and when the fixed pad is stressed downward, it will control the movable pads to gather towards the middle through the rotating plate.

[0007] Preferably, springs are fixedly provided at the bottoms of both the movable pad and the fixed pad, the bottoms of the springs are fixedly connected to the top of the arc-shaped plate, and control frames are fixedly provided on both sides of the rear side of the top of the arc-shaped plate.

[0008] Preferably, two symmetrical threaded grooves are formed on the back surface of the fixed pad, an adjusting screw is slidably provided in the control frame, and the adjusting screw is adapted to the threaded groove.

[0009] Preferably, adjusting rods are rotatably provided on both sides of the inner wall of the base, the adjusting rods are movably connected to the back surface of the movable pad, limit blocks are slidably provided on both sides of the base, a limit screw penetrates through one side of the limit block, a handle is provided on one side of the limit block, and one side of the handle is fixedly connected to one side of the movable seat.

[0010] Preferably, a bracket is fixedly provided on the back surface of the base, connecting frames are fixedly provided on both sides of the bracket, the bottoms of the connecting frames are fixedly connected to the back surface of the base, and a knob is threadedly penetrated through one side of the top of the bracket.

[0011] Preferably, a positioning disk is movably provided on the knob, the positioning disk is circular, a groove is formed on one side of the positioning disk, a soft pad is provided in the groove, the positioning disk can be controlled to move back and forth through the knob, and the positioning disk is located at the center of the arc of the base.

[0012] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) A control structure is provided on the operating bed. The control structure can support the top position of the patient through the fixed pad and locate the center position of the patient's head through the positioning disk. When medical staff need to rotate the head of a general anesthesia patient lying on the operating table during an eye medical operation, there is no need to additionally add medical staff to continuously control the deviation position of the patient's head. Only by controlling the movement of the movable seat in the base can the angle of the head of the general anesthesia patient be rotated, making it more convenient and faster for medical staff to change the direction of the patient's head. The positioning disk determines the center position of the base. When the patient's head is resting on the fixed pad, the position of the human cervical vertebra and head can be determined, and the head rotates around the cervical vertebra as the center, so that the real human head-turning environment can be simulated, and no discomfort will be caused to the patient during long-term turning. While protecting the patient and making it more comfortable, it is also more convenient for medical staff to perform surgical treatment on general anesthesia patients, greatly increasing the practicability of a single flat operating bed; (2)On both sides of the fixed pad, movable pads are also provided. The movable pads can be used in conjunction with the fixed pad. When the patient's head is placed on the fixed pad, due to the pressure of gravity, the movable pads will gather towards the center and form a clamping protection for the patient's head. The fixed pad and the movable pads are in soft contact with the patient's skin, so they will not cause any discomfort to the patient. The clamping fixed pad and movable pads can also be more firm and stable when the patient's head is turned during general anesthesia surgery, and will not slide due to the small friction between the hair and the soft pad, affecting the operation of medical staff during the surgery. The moving method of the movable seat is also simple and fast. Just loosen the fixing screw and hold the handle to slowly adjust the turning of the patient's head. Brief Description of the Drawings

[0024] The working principle and usage process of the present invention: When the patient lies on the operating table 1, the patient's head should be directly above the fixed pad 405. After the patient's head is rested on the fixed pad 405, the fixed pad 405 will move downward under the action of gravity and squeeze the spring 406 at the central part. After the fixed pad 405 moves downward, it will drive the movable pads 402 on both sides to stretch the springs 406 at both sides and move closer to the middle to stably semi-wrap the patient's head on the fixed pad 405. After the patient's head is placed properly, it is necessary to check whether the center of the head is at the same height as the positioning disk 3. If not, the height of the patient's head needs to be controlled by the adjusting screw 414 and the control frame 409 to make the center of the head at the same height as the positioning disk 3. Since the positioning disk 3 can rotate, it will not affect the subsequent rotation of the user's head. If there is a certain distance between the patient's head and the positioning disk 3, the position of the positioning disk 3 can also be adjusted by rotating the knob 6 to make it stick to the center of the patient's head. After adjustment, general anesthesia can be administered to the patient and subsequent operations can be carried out. During the operation, when it is necessary to rotate and adjust the user's head, the medical staff only need to hold the handle 403 with their hand and lift it upward to one side. The handle 403 will drive the movable seat 411 to move upward along the sliding groove 413. The movable seat 411 drives the patient's head to rotate around the cervical vertebra as the center of the circle. After rotating to the appropriate position, the adjusting screw 414 can be rotated and tightened. After adjustment, the patient's head can be fixed to rotate it to a position suitable for the operation.
