Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of an orthopedic arm fixation bracket, including a fixation base 1. A movable ring 2 is hinged to the top of the fixation base 1. The movable ring 2 and the fixation base 1 work together to position the patient's arm. A movable block 7 is fixedly connected to the outer wall of the movable ring 2. A long rod 8 is slidably connected through the inner wall of the movable block 7. The middle part of the long rod 8 is cylindrical, and a protrusion is provided at its right end. A groove corresponding to the protrusion is formed on the inner wall of the movable block 7, allowing the long rod 8 to move left and right. A fixation block 6 is fixedly connected to the outer wall of the fixation base 1. A limit mechanism is provided on the inner wall of the fixation block 6. The bottom end of the fixation base 1 is fixedly connected to... There is a movable column 9, and a support column 10 is slidably connected to the outer wall of the movable column 9. The inner wall of the support column 10 has a slot corresponding to the movable column 9, allowing the movable column 9 to move vertically. The bottom end of the support column 10 is fixedly connected to a base 12, which supports the entire device. The inner wall of the movable column 9 is provided with an adjustment component. The limiting mechanism includes a round rod 3. The inner side wall of the round rod 3 is elastically connected to a fixed block 6 through a movable spring 4. The right end of the round rod 3 is fixedly connected to a locking block 5. The round rod 3 passes through and is slidably connected to the inner wall of the fixed block 6. The fixed block 6 has a slot corresponding to the round rod 3, allowing the round rod 3 to move left and right.

[0033] Reference Figure 1 and Figure 4 The adjustment assembly includes a pull rod 11, on which a guide rod is provided to guide the pull rod 11. The inner side wall of the pull rod 11 is elastically connected to a movable column 9 via a movable spring 13. The pull rod 11 passes through and is slidably connected to the inner wall of the movable column 9. The upper end of the pull rod 11 is U-shaped, and the lower end is L-shaped. The movable column 9 has a slot corresponding to the pull rod 11, allowing the pull rod 11 to move back and forth. The pull rod 11 passes through and is inserted into the inner wall of a support column 10. The support column 10 has a slot corresponding to the pull rod 11. In the initial state, the pull rod 11 is inserted into the slot. The inner side wall of the pull rod 11 is fixedly connected to one end of the movable spring 13, and the other end of the movable spring 13 is fixedly connected to the outer wall of the movable column 9. When the pull rod 11 moves forward, the movable spring 13 is compressed. When resetting, the elastic force of the movable spring 13 carries the pull rod 11 back to its original position.

[0034] Reference Figures 1-3The inner sidewall of the round rod 3 is fixedly connected to one end of the movable spring 4, and the other end of the movable spring 4 is fixedly connected to the left sidewall of the fixed block 6. When the round rod 3 moves to the right, the movable spring 4 is compressed. When resetting, the elastic force of the movable spring 4 is used to reset the round rod 3. The locking block 5 is inserted into the right sidewall of the fixed block 6. The fixed block 6 has a slot, which is slightly larger than the locking block 5, so that the moving block 7 is not blocked by the locking block 5 when it rotates with the moving ring 2. The locking block 5 is inserted into the right sidewall of the moving block 7. The moving block 7 has a slot corresponding to the locking block 5. In its initial state, the locking block 5 is inserted into the slot, the bottom end of the moving block 7 is in contact with the top end of the fixed block 6, the long rod 8 is locked onto the outer wall of the round rod 3, the long rod 8 is provided with a rectangular strip, and the round rod 3 is provided with a slot slightly larger than the rectangular strip, so that the long rod 8 is not obstructed when it rotates with the moving ring 2. There are multiple sets of long rods 8, and the multiple sets of long rods 8 are interlocked with each other. The long rod 8 is provided with a slot corresponding to its own protrusion. When the protrusion is inserted into the slot, it will make the two adjacent sets of long rods 8 maintain the same moving trajectory. The right side wall of the locking block 5 is in contact with the left side wall of the round rod 3.

[0035] Working principle: When it is necessary to release the local positioning of the patient's arm, the hand moves the long rod 8 to the right. The long rod 8 will move the round rod 3 and the locking block 5 to the right. The round rod 3 will squeeze the movable spring 4. When the locking block 5 separates from the groove on the moving block 7, the hand rotates the long rod 8 counterclockwise. The long rod 8 will rotate the moving ring 2 around the hinge point of the moving ring 2. When the long rod 8 and the round rod 3 are no longer in contact, under the elastic force of the movable spring 4, the round rod 3 and the locking block 5 will move to the initial position. When it is necessary to close the moving ring 2, the hand moves the round rod 3 to the right. When the round rod 3 and the locking block 5 no longer block the groove of the moving block 7, the hand rotates the long rod 8 clockwise. The long rod 8 will rotate the moving ring 2. When the long rod 8 is engaged in the groove of the round rod 3, the hand releases the round rod 3. The elastic force of the movable spring 4 will move the round rod 3 to the initial position, completing the limitation of the moving ring 2. At this time, the moving ring 2 and the fixed seat 1 are closed.

[0036] When it is necessary to release the patient's arm from its position, the hand moves the long rod 8 to the right. When the long rod 8, along with the round rod 3 and the locking block 5, disengages from the slot of the moving block 7, the long rod 8 continues to move to the right. When the first set of long rods 8 inserts into the slot of the second set of long rods 8, as the first set of long rods 8 continues to move, the remaining sets of long rods 8 will interlock with each other and maintain the same movement trajectory as the first set of long rods 8. The remaining sets of round rods 3 separate from the slots on the moving block 7 as the long rods 8 move. Then, the hand flips the first set of long rods 8, which will cause multiple sets of long rods 8 to flip around the hinge point. When all the round rods 3 are no longer in contact with the long rods 8, all the round rods 3 return to their initial state under the elastic force of the movable spring 4. When overall closure is required... The hand moves the first set of round rods 3 to the right, causing the first set of locking blocks 5 to move to the right. When the first set of locking blocks 5 contacts and presses the second set of round rods 3, the second set of round rods 3, along with the second set of locking blocks 5, maintains the same movement trajectory as the first set of round rods 3. The remaining sets of locking blocks 5 also move along the same trajectory as the second set of locking blocks 5. When all locking blocks 5 no longer obstruct the slots of the moving block 7, the hand flips the first set of long rods 8, causing the remaining sets of long rods 8 to flip as well. When the long rods 8 engage with the slots of the round rods 3, the hand releases the round rods 3, and the spring force of the movable spring 4 moves the round rods 3 back to their initial position. All locking blocks 5 engage with the slots of the moving block 7, completing the limiting of the moving ring 2. At this point, the device returns to its original state. Figure 1 As shown, if you need to release the patient's arm from the positioning again, simply repeat the above steps.

[0037] When the device height needs to be adjusted, move the lever 11 forward. The lever 11 will compress the moving spring 13. When the lever 11 separates from the slot of the support column 10, move the lever 11 upward. The lever 11 will move the fixed seat 1 and the moving ring 2 upward. When the device is adjusted to the required height, release the lever 11. The elastic force of the moving spring 13 will allow the lever 11 to be inserted into the slot of the movable column 9, thus limiting the height of the movable column 9. When the device height needs to be lowered, move the lever 11 downward. The lever 11 will move the fixed seat 1 and the moving ring 2 downward. When the device is adjusted to the required height, release the lever 11, allowing the lever 11 to be inserted into the slot of the support column 10, thus limiting the height of the movable column 9. If the device height needs to be adjusted again, simply repeat the above steps.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
