The transition arc surface 219 cooperates with a downwardly disposed corner of the triangular clamping block 27 .

[0038] A flat groove 216 intersecting with and communicating with the groove 214 is provided between the left and right outer walls below the first connecting block 21. A detachable anti-rotation plate 28 is inserted into the flat groove 216. A flange 281 is formed downwardly on the left or right edge of the anti-rotation plate 28.

[0039] A first countersunk hole 231 is provided at the front end of the positioning block 23, and correspondingly, a second countersunk hole 218 cooperating with the first countersunk hole 231 is provided on the front inner wall of the groove 214. A second spring 29 is also provided inside the groove 214 and is located in front of the positioning block 23 and is always in a compressed state.

[0040] A limiting curved surface 224 is formed between the lower edge of the opening of the positioning notch 223 and the lower edge of the root of the arc-shaped protrusion 222 . The limiting curved surface 224 cooperates with the lower portion of the bottom surface of the opening groove 212 .

[0041] A first connecting groove 2110 is provided at the front end of the first connecting block 21, and a second connecting groove 225 is provided at the rear end of the second connecting block 22. The rear ends of the two orthopedic rods 11 in the front fixing frame 1 are respectively inserted into the first connecting grooves 2110 fixed on the first connecting block 21 in the two positioning hinges 2, and the front ends of the two orthopedic rods 11 in the rear fixing frame 1 are respectively inserted into the second connecting grooves 225 fixed on the second connecting block 22 in the two positioning hinges 2.

[0042] The strap combination in the front fixing frame 1 is arranged in a centrally symmetrical manner with the strap combination in the rear fixing frame 1; an arcuate strip 3 is also fixed to the lower or upper side of the front end of the two orthopedic rods 11 in the front fixing frame 1 and the upper or lower side of the rear end of the two orthopedic rods 11 in the rear fixing frame 1, and the two arcuate strips 3 are arranged in a centrally symmetrical manner.

[0043] The front ends of the two orthopedic rods 11 in the front fixing frame 1 and the rear ends of the two orthopedic rods 11 in the rear fixing frame 1 are formed with a symmetrically arranged bending section 111 in the direction of an arc-shaped strip 3 on the same side, and the two ends of each arc-shaped strip 3 are respectively fixed to the ends of the two bending sections 111 on the same side.

[0044] One end of each binding strap 12 is fixed to one of the orthopedic rods 11 in the fixing frame 1 where it is located, and the other end of each binding strap 12 is detachably fixed to another orthopedic rod 11 in the fixing frame 1 where it is located.

[0045] Directions:

[0046] First, remove the detachable end of each strap 12 from the corresponding orthotic rod 11, then extend the patient's arm to be rehabilitated laterally backward between the two orthotic rods 11 in each fixing frame 1 with the wrist facing upward, so that the arm elbow joint is disposed between the two positioning hinges 2, and then fix the detachable end of each strap 12 on the corresponding orthotic rod 11 again and tighten it in turn, so that the wearing of the positioning brace is completed, and a front arc-shaped strip 3 is buckled on the lower surface of the upper arm, and a rear arc-shaped strip 3 is buckled on the upper surface of the lower arm.

[0047] Afterwards, the lower arm can be swung upward and back and forth for rehabilitation training with the assistance of medical staff. The two fixing frames 1 can effectively prevent the elbow joint between the upper arm and the lower arm from shifting and can also effectively prevent the upper arm and the lower arm from deforming during swinging.

[0048] When the upper and lower arms need to be kept straight for positioning, the patient straightens the arm first. During this process, the second connecting block 22 swings with the orthopedic rod 11 relative to the first connecting block 21 until the limiting curved surface 224 abuts against the bottom surface of the opening groove 212. After that, the second connecting block 22 cannot continue to rotate, and the arm reaches the straight state. At this time, the positioning notch 223 rotates to the rear of the positioning block 23. Subsequently, the upper end of the traction block 24 is pushed backward by hand to make the rotating arc surface 243 and the guide arc surface 215 collide. The second spring 29 is provided with a spring 29 which is adapted to move the second connecting block 22 relative to the first connecting block 21. The spring 29 is provided with a spring 29 which is adapted to move the second connecting block 22 relative to the first connecting block 21. The spring 29 is provided with a spring 29 which is adapted to move the second connecting block 22 relative to the first connecting block 21. The spring 29 is provided with a spring 29 which is adapted to move the second connecting block 22 relative to the first connecting block 21.

[0049] During the swinging process of the traction block 24, the anti-loosening component will swing in the same direction as the traction block 24. Before the second connecting block 22 swings, the end of a downwardly set corner of the triangular block 27 in the anti-loosening component is pressed against the transition arc surface 219 with the help of the first spring 26. When the anti-loosening component swings along with the second connecting block 22, the end of a downwardly set corner of the triangular block 27 will slide along the transition arc surface 219 and force it to slowly rise and gradually compress the first spring 26. When the end of a downwardly set corner of the triangular block 27 reaches the locking notch 217, the triangular block 27 will be inserted downward into the locking notch 217 under the action of the rebound force of the first spring 26. In this way, even if the upper end of the traction block 24 is accidentally hit, the traction block 24 will not shift, because the triangular block 27 is inserted into the locking notch 217, and the position of the traction block 24 is limited by the pull rod 25.

[0050] When the rotation function of the second connecting block 22 needs to be restored again, the pull buckle 251 is first pinched by hand and pulled upward to drive the triangular block 27 to move upward with the help of the pull rod 25 until a corner set downward on the triangular block 27 completely leaves the blocking notch 217. During this process, the first spring 26 is compressed; then the upper end of the traction block 24 is swung forward to drive the triangular block 27 to swing forward to above the transition arc surface 219, and then the pull buckle 251 can be released to allow the triangular block 27 to move downward with the help of the rebound force of the first spring 26 until it is The end portion at a corner set downward on the triangular clamping block 27 is pressed against the transition arc surface 219 by means of the first spring 26; in the above process, the second spring 29 is compressed, but according to the lever principle, the central axis of the rotating arc surface 243 and the guide arc surface 215 is a rotating fulcrum. Since the second spring 29 is at a short distance from the above rotating fulcrum, the thrust torque generated by the rebound force of the second spring 29 on the positioning block 23 is small, and the positioning block 23 cannot be spontaneously pushed to move backward, so the traction block 24 will not automatically swing backward after swinging forward.

[0051] When the anti-loosening assembly is working normally, the anti-rotation plate 28 can be not used and can be removed. However, when the anti-loosening assembly fails and the triangular clamping block 27 cannot be moved up and down, the second connecting block 22 cannot be locked. At this time, the side of the anti-rotation plate 28 without the flange 281 can be inserted horizontally to the left or right into the flat cut groove 216 until the flange 281 fits against the corresponding side outer wall of the first connecting block 21; when the anti-rotation plate 28 is inserted, the outer wall of the side of the baffle 242 away from the inside of the slot 241 is parallel to the upper or lower inner wall of the flat cut groove 216, so that the anti-rotation plate 28 can be inserted smoothly. After the anti-rotation plate 28 is inserted, the inner wall of the anti-rotation plate 28 fits against the outer wall of the side of the baffle 242 away from the inside of the slot 241. In this way, the traction block 24 cannot rotate because the anti-rotation plate 28 limits the rotation of the baffle 242 on the traction block 24, thereby also playing a locking role.

[0052] The present invention can lock the first connecting block 21 and the second connecting block 22 with each other by means of the positioning hinge 2 to prevent relative rotation between the two fixators 1, thereby preventing the patient from rotating the joints of the upper limbs or lower limbs due to unconsciousness or instinctive reaction, thereby playing a role in resetting and fixing the bones; and the positioning hinge 2 adopts the method of inserting or leaving the positioning notch 223 by the rear end of the positioning block 23 to limit and restore the rotation of the arc-shaped protrusion 222, thereby replacing the method of locking and unlocking by using a knob screw in the prior art; at the same time, the movement of the positioning block 23 can be achieved only by pushing and pulling the traction block 24, thereby greatly simplifying the locking and unlocking operation steps, thereby achieving the effect of saving time and effort for easy use; in addition, the present invention also effectively increases the locking strength by means of the mutual cooperation between the triangular clamping block 27 and the clamping notch 217 in the anti-loosening component, and once locked, it will not loosen; it is worth mentioning that the present invention can also lock the first connecting block 21 and the second connecting block 22 by means of the anti-rotation plate 28 when the anti-loosening component fails in case of emergency, thereby significantly improving the reliability of use.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
