[0002] Clinical orthopedics refers to clinical medicine that diagnoses and treats diseases such as human skeletal dislocation, fractures, and bone trauma. When performing surgical treatment on patients with spinal trauma, clinical orthopedics usually uses surgical fixation devices to assist. Fractures and dislocations caused by degeneration, tumors, and physical trauma may cause various injuries to the human spine. Spinal fractures are very common, accounting for about 5%-6% of all fractures in the body. Spinal fractures may be combined with spinal cord or cauda equina injuries, especially cervical fractures. Dislocations combined with spinal cord injuries can reportedly reach up to 70%, which can cause severe disability or even loss of life. Therefore, effective treatment of spinal fractures is of great significance.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can effectively restrain and fix the patient's shoulders and hips through the arrangement of the support platform, elastic straps, insertion holes, Velcro, drive motor, adjustment screw, first synchronous wheel and mobile frame, so as to prevent the patient's shoulders and hips from shaking during the surgical treatment. In addition, under the cooperation of the first synchronous wheel, synchronous belt, second synchronous wheel, third synchronous wheel, rotating shaft, bevel gear, gear ring, turntable, guide seat, rotating shaft, rotating wheel, U-shaped frame, support cylinder, limiting pressure plate, first spring and leg bracket, the patient's legs can be effectively limited to prevent the patient from kicking during the surgical treatment. At the same time, the third synchronous wheel can be used to adjust the position of the patient's legs. The step wheel, rotating rod, L-shaped rotating rod, connecting plate, L-shaped fixing rod, first piston, pressure cylinder, first non-return valve, second non-return valve, airway tube, air cylinder, second piston, L-shaped push rod, side splint and movable splint cooperate to effectively restrain and fix both sides of the patient's waist to avoid twisting of the patient's waist during surgical treatment, thereby achieving the effect of multi-point synchronous fixation of the patient's shoulders, hips, waist and legs during spinal trauma surgery, which greatly avoids the patient's movements during the surgical treatment and ensures that the medical staff's surgical operations can be carried out normally.

[0017] 2. The present invention can drive the toothed plate to move when the U-shaped frame moves downward by arranging the transverse axis, circular gear, toothed plate, fixed transverse plate and placement table. The movement of the toothed plate can drive the circular gear and the transverse axis to rotate along the bearing on the support table. The rotation of the transverse axis can drive the fixed transverse plate and the placement table to rotate, so that the placement table can rotate ninety degrees and be located directly above the limiting pressure plate, thereby facilitating the medical staff to support and place instruments or surgical instruments during surgery. By arranging the pin groove, the second cavity, the pin column and the third spring, the movable splint and the side splint can be effectively locked and limited to prevent the movable splint from being drawn out of the inner cavity of the side splint. At the same time, when the personnel press the pin column to move, the third spring can be locked. The spring is compressed until the pin can be disengaged from the surface of the pin groove, thereby releasing the limit between the movable splint and the side splint. Then the personnel can pull the movable splint to move and adjust along the inner cavity of the side splint, which is convenient for the personnel to adjust the working height between the movable splint and the side splint according to the height of both sides of the patient's waist. Through the setting of the limit clamp hole, the first cavity, the limit clamp rod and the second spring, a certain sense of resistance can be formed in the process of the personnel pushing the limit pressure plate and the support cylinder to rotate along the bearing on the U-shaped frame, thereby preventing the limit pressure plate and the support cylinder from rotating during non-personnel operation, and enabling the personnel to detach the limit pressure plate from above the patient's legs after the patient's operation is completed, so that the patient can lift his legs.

[0018] 3. The present invention achieves the purpose of stably supporting the rotating shaft and the rotating shaft by setting the support frame, and avoids the rotating shaft and the rotating shaft from tilting due to force during the rotation process. The purpose of stably supporting the rotating rod by setting the supporting cross plate is achieved, and avoids the rotating rod from tilting due to force during the rotation process. The first sealing ring and the second sealing ring are provided to improve the sealing between the first piston and the pressure cylinder, and the second piston and the air guide cylinder respectively. The fourth spring can be compressed during the movement of the second piston, so that the fourth spring can exert pressure on the second piston. Tension is generated, and in the subsequent exhaust process, the fourth spring can push the second piston to move and reset. Through the setting of the pressure relief valve, the pressure can be relieved when the air pressure inside the airway tube and the air cylinder is too high, which effectively avoids the side splints and the movable splints causing damage to both sides of the patient's waist due to excessive pressure. Through the setting of the control valve, it is convenient for medical staff to discharge the air inside the airway after the operation is completed. Through the setting of the guide vertical rod, the purpose of guiding the mobile frame is achieved, and the mobile frame is prevented from tilting during the movement. Through the setting of the sterile pad and the neck pillow, it is convenient to support the patient. BRIEF DESCRIPTION OF THE DRAWINGS

The rotation of the second synchronous wheel 41 can drive the rotating shaft 27 and the bevel gear 26 to rotate. The rotation of the bevel gear 26 can drive the gear ring 38, the turntable 22, the guide seat 35 and the rotating shaft 23 to rotate. Under the action of the rotation of the guide seat 35, it can contact the surface of the rotating wheel 24 and push the rotating wheel 24 downward through the inclined surface. The movement of the rotating wheel 24 can drive the U-shaped frame 17, the support cylinder 16 and the limiting pressure plate 7 to move. , and can compress the first spring 25. Under the action of the continuous rotation of the guide seat 35, the rotating wheel 24 can contact the bottom plane of the guide seat 35, and the limiting pressure plate 7 can contact the top of the leg bracket 6. Under the action of the cooperation between the limiting pressure plate 7 and the leg bracket 6, the patient's legs can be effectively limited to prevent the patient from kicking during the surgical treatment. At the same time, during the rotation of the third synchronous wheel 34, the rotating rod 30 and the L-shaped rotating rod 53 can be driven to rotate. When the L-shaped rotating rod 53 rotates, it can drive the L-shaped fixing rod 55 and the first piston 56 to reciprocate along the inner cavity of the pressurizing cylinder 10 through the connecting plate 54, and the first piston 56 moves back and forth. During the reciprocating movement, the outside air can be drawn into the pressurizing cylinder 10 through the first one-way valve 32, and the air can be sent into the air cylinder 12 through the second one-way valve 33 and the air duct 13. While the air is continuously transported to the air cylinder 12, the air pressure inside the air cylinder 12 increases, and the increased air pressure can push the second piston 36, the L-shaped push rod 46, the side splint 11 and the movable splint 14 to move, so that the side splint 11 and the movable splint 14 can be tightly attached to the two sides of the patient's waist under the action of movement, so that the two sides of the patient's waist can be effectively restrained and fixed, preventing the patient's waist from twisting during surgical treatment.
