Before the scheme is used, the front sole fixing plate 42 is parallel to the front arm fixing plate 22, and the rotating locking structure 33 and the sliding locking structure are in a locking state. If the fixing device is used without traction, but only needs to be reset and fixed by a rotating and turning top method, the arm of a patient is firstly placed on the fixing device, the elbow is positioned at the position of the elbow rotating shaft 73, and the upper arm is fixed on the upper arm fixing part 13 through the upper arm strap 11. The forearm is lowered forward and secured to the forearm attachment plate 22 by means of a forearm strap 23, with the support part 24 of the forearm support arrangement 2 resting on the forearm support 12.

Then the sliding lock structure is released to adjust the position of the sliding frame 32 until the front sole fixing plate 42 reaches the front sole position of the hand of the patient, the front sole of the patient is placed on the front sole fixing plate 42 and is connected with the fingers of at least two patients through the finger sleeves 43, the wrist rotating shaft 35 is located at the wrist position of the patient, and then the lock nut 34 is rotated to clamp the sliding rail to realize the locking of the sliding lock structure. Since the length difference range of the palms between people is smaller than that of the forearms, the distance between the wrist rotating shaft 35 and the palm fixing plate is relatively fixed and is relatively close to the wrist position of the patient, and the defect that the rotating track of the rotating wrist and the forepaw fixing plate 42 is greatly staggered due to the fact that the distance between the rotating shaft and the wrist is larger during rotation is avoided. In the case of the folding top reset after the traction reset, the wrist rotation shaft 35 needs to be determined according to the position after the traction, and therefore should slide relative to the guide rail 21 before the determination of the position, and be locked and positioned at the hand position after the traction.

The rotating locking structure 33 is loosened, the rotating frame 31 can rotate around the wrist rotating shaft 35, then a doctor rotates the wrist of the patient by a professional method, the top folding method resetting process is completed, the wrist is temporarily fixed at the top folding rear position by one hand, meanwhile, the locking screws of the rotating locking structures 33 at the left side and the right side are successively screwed by the other hand, the locking screws drive the locking bearing bushes 335 to press the fixed bearing bushes 334, the locking bearing bushes 335 and the fixed bearing bushes 334 clamp the wrist rotating shaft 35 relatively, the locking of the rotating locking structure 33 is realized, and the wrist of the patient can be kept at the top folding reset position. Then, the wrist and the surrounding portion in this state are plastered, and the fixed posture is maintained until the plaster is set.

Obviously, the above process enables a doctor to keep the wrist in the folded posture by one hand and conveniently realize the relative fixation of the rotating frame 31 and the sliding frame 32 after rotation by the other hand, so that at least one doctor does not need to maintain the folded posture of the wrist of a patient during subsequent plaster application, the posture of the wrist part of the doctor in the folded posture is conveniently maintained, and the problem that the wrist moves in the plaster application and plaster curing process to cause the displacement of the bone or ligament at the fracture part is avoided.

If the fixing device needs to stretch and draw the fracture part of the wrist before use, the folding top fixing structure is firstly rotated to enable the guide rail 21 to be upright, the connecting screw rod 54 of the detachable connecting component 5 is inserted into the connecting groove, and then the T-shaped connecting rod 52 is screwed down to enable the sliding end part 64 to be fixedly connected with the hand fixing component 4. The patient's upper arm and forearm is then secured to the upper arm securing portion 13 and forearm fixing plate 22, respectively, as previously described, the slider locking arrangement is released and the slider end member 64 is then adjusted until the patient's forefoot can be fixedly attached to the forefoot fixing plate 42. After the parts of the arm are fixed, the upper end of the threaded connecting rod 63 with the threads extends out of the top of the upper support 61, the lower end of the T-shaped handle 62 is connected with the upper end of the threaded connecting rod 63, the lower end of the T-shaped handle 62 abuts against the top of the upper support 61 and then the T-shaped handle 62 continues to rotate, the hands of a patient can be further pulled upwards through the threaded connecting rod 63 to be stretched, and the pulling and resetting effects of the wrist parts are achieved. And after traction reduction is finished, the sliding locking structure is locked in a traction state, so that the traction state of the hand fixing component 4 on the fracture part of the wrist can be kept, and displacement is avoided. Then the T-shaped connecting rod 52 is rotated to lead the clamping piece 53 to be relatively far away from the loose sliding end part 64, when the distance between the clamping pieces 53 reaches a certain distance, the whole folding top fixing structure can be rotated to lead the connecting screw rod 54 to be separated from the opening of the connecting groove, and then the connecting screw rod is converted into a state that the forearm is supported by the forearm supporting structure 2 after being put down, and then the folding top fixing structure is operated according to the method to realize the folding top and the folding top gesture maintenance of the wrist part, and finally the process of plaster fixation is finished.

In the method, the stretching traction is reset, the forearm is pulled under an upright posture, and the purpose is to ensure that the direction of the forearm under the action of gravity is parallel to the direction of the traction action, so that the influence of the action force of other directions on the arm on the traction effect during traction is reduced. And roll over the wrist and roll over when pushing up owing to roll over the top and be rotary motion, needn't consider the influence of gravity, roll over the back in addition and will make things convenient for the operation to rotate locking structure 33 and reserve sufficient space for the process of later playing the gypsum to it prevents the swing to make things convenient for the bearing forearm, so this scheme lets roll over a fixed knot and construct and can rotate the slope or the gesture of keeping flat, lets anterior bearing structure support the forearm, keeps forearm position stability, also makes things convenient for follow-up to reset and play the gypsum.
