It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, as well as the use of drugs, surgery and physical methods to maintain and develop the normal form and function of this system, and treat injuries and diseases of this system. Patients with severe trauma due to trauma or accidents usually have injuries to the bones in their arms or legs and need orthopedic treatment. In the recovery stage after treatment, patients need to rest in bed.

At this time, the two limiting plates on the bottom wall of the fixing plate are just aligned with the mounting holes and enter the limiting ring grooves through the mounting holes. When the rotating part is started to drive the two arc plates closer to each other, the fixing plate rotates synchronously with the output shaft of the rotating part, and the limiting plates and the mounting holes are misaligned, thereby fixing the fixing seat and the placing plate. When the patient needs to move his arm or leg away from the fixing seat, the rotating part continues to rotate, and the two arc plates move away from each other. At this time, the fixing plate continues to rotate with the output shaft of the rotating part, and the limiting plates come to the position aligned with the mounting holes again, so that the fixing seat can be removed from the placing plate. The present application can simultaneously realize the movement of the arc plate and the locking of the fixing seat through the rotating part, without the need for a separate driving structure, and has high practicality and economic benefits.

Two limiting rods 73 are both arranged in the installation cavity 17, and the two limiting rods 73 are both arranged parallel to the serial screw rod 71, and the two limiting rods 73 pass through the pushing plate 72.

[0050] Reference Figure 2 , Fig. 9 and Fig.10 The locking nut 76 is used to lock the locking nut 78 and the locking nut 77 is used to lock the locking nut 78. When the locking nut 76 is in the unlocking state, the locking nut 77 is used to lock the locking nut 78. When the locking nut 76 is in the unlocking state, the locking nut 77 is used to lock the locking nut 78.

[0051] The implementation principle of the anti-collision correction device for critically ill patients in the embodiment of the present application is as follows: when in use, the mounting plate 5 is fixed to the bed, the positioning column 15 of the fixing seat 1 is placed on the placement plate 51 corresponding to the positioning hole 5124, the patient places the arm or leg to be fixed and corrected into the first placement groove 11, the rotating member 44 is started, and the output shaft of the rotating member 44 drives the rotating arm 45 to rotate. Since the driving shaft 451 is against the inner wall of the track frame 46, the track frame 46 can be pushed to move, and then the rotation of the output shaft of the rotating member 44 is converted into the sliding of the track frame 46. At this time, the track frame 46 can drive the driving rack 41 connected thereto to move, and the driving gear The transmission of 43 makes the driving rack 41 on the other side move in the opposite direction at the same time. Driven by the two driving racks 41, the two arc-shaped plates 2 above the fixed seat 1 can approach or move away from each other. When the two arc-shaped plates 2 are close to each other, they can form a closed area with the first placement groove 11. The airbag 3 is inflated by the inflatable member 31, so that the airbag 3 can expand and contact the patient's arm or leg, thereby improving the patient's unconscious movements, and at the same time preventing accidental collisions, ensuring that the renewal can be restored stably; at the same time, the output shaft of the rotating member 44 drives the fixed plate 14 to rotate, so as to fix the fixed seat 1 and the mounting plate 5, thereby providing the overall stability of the device of the present application.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
