[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 An orthopedic bone correction and reduction tool includes a support component 1 for lifting the height to be flush with the limb, a positioning component 2 for limiting the sliding direction arranged on the top of the support component 1, a correction component 3 for applying pressure to the bone and correcting it and adjusting it according to the ups and downs of each section of the limb arranged on the top of the positioning component 2, and a locking component 4 for plugging and unplugging the connection to maintain pressure and prevent loosening arranged on the top of the correction component 3.

[0024] In this embodiment: the support assembly 1 includes a pneumatic telescopic column 101, a pedal 102 is installed at the bottom of the pneumatic telescopic column 101, a mounting frame 103 is arranged at the output end of the pneumatic telescopic column 101, a bidirectional threaded rod 104 is rotatably arranged at the top of the mounting frame 103, sliding rods 105 are arranged on both sides of the bidirectional threaded rod 104, the bidirectional threaded rod 104 is connected to the output end of the hand crank 106, and a hand crank 106 for driving the bidirectional threaded rod 104 to rotate is arranged at one end. The pneumatic telescopic column 101 is stepped on the pedal 102 to lift the top mounting frame 103, and the position is matched with the body height. The patient's limb is placed between the two groups of clamping plates 301, and the patient's part to be fixed is placed between the two groups of clamping plates 301. The hand crank 106 is shaken to rotate the bidirectional threaded rod 104, driving the two limit frames 201 to close along the sliding rod 105. During the closing process of the limit frames 201, the clamping plates 301 are driven to fit the limbs.

[0025] In this embodiment: the positioning component 2 includes two symmetrically arranged limit frames 201, a number of dividing columns 202 are evenly fixedly arranged on the inner side of the limit frame 201, a number of through holes 203 are equidistantly opened on the top surface of the limit frame 201, and the pins 402 are inserted to connect the through holes 203 and the slots 302 at the bottom thereof, so as to fix all the clamping plates 301 on the limit frame 201 and continuously apply pressure to correct the bones.

[0026] In this embodiment: the correction component 3 includes a number of uniformly arranged compression plates 301, a number of slots 302 are equidistantly provided on the top of the compression plate 301, and a clamping block 303 is fixedly provided on the outside of the compression plate 301. After the compression plate 301 touches the limb, it moves outward along the limit frame 201. The thickness of each part of the patient is different, so the outward movement distance of each compression plate 301 is also different. The compression plates 301 with different moving distances fit closely to the diseased part.

[0027] In this embodiment: the locking assembly 4 includes two symmetrically arranged plug plates 401, a number of latches 402 are evenly fixedly arranged on the bottom of the plug plates 401, a handle 403 is fixedly installed on the top surface of the plug plates 401, the latches 402 are plugged and unplugged with the limit frame 201 and the clamping plate 301 respectively, and a handle 403 is welded on the top of the plug plates 401 to reduce the difficulty of pulling out the plug plates 401. The handle 403 is pulled before use, and the latch 402 is driven to move out of the slot 302 and the through hole 203 through the plug plates 401. At this time, the clamping plate 301 loses connection with the limit frame 201, and the clamping plate 301 can slide left and right. After the treatment is completed, the latch 402 is pulled out again, and all the card blocks 303 are pushed until they are close to the limit frame 201, thereby completing the resetting of the clamping plate 301.

[0028] Working principle: When in use, pull the handle 403, and drive the latch 402 to move out of the slot 302 and the through hole 203 through the plug plate 401. At this time, the connection between the clamping plate 301 and the limit frame 201 is lost, and the clamping plate 301 can slide left and right. Step on the pedal 102 to make the pneumatic telescopic column 101 lift the top mounting frame 103. After the position matches the body height, put the patient's limb between the two sets of clamping plates 301, put the patient's part to be fixed between the two sets of clamping plates 301, shake the hand crank 106 to rotate the bidirectional threaded rod 104, drive the two limit frames 201 to close along the slide rod 105, and drive the clamping plate 301 to fit the limb during the closing process of the limit frame 201 After the compression plate 301 touches the limb, it moves outward along the limit frame 201. The thickness of each part of the patient is different, so the outward movement distance of each compression plate 301 is also different. The compression plates 301 with different movement distances are closely fitted to the diseased part, and the pin 402 is reinserted to connect the through hole 203 with the slot 302 at its bottom, so as to fix all the compression plates 301 on the limit frame 201, and continuously apply pressure to correct the bones. When the patient feels uncomfortable and needs fine-tuning, there is no need for medical staff to do it personally, which saves manpower costs. After the treatment is completed, the pin 402 is pulled out again, and all the card blocks 303 are pushed until they are close to the limit frame 201, and the resetting of the compression plates 301 is completed.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
