[0002] An artificial bone stent is a medical device used for fracture treatment and bone injury repair.

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] A positioning device for processing an artificial bone scaffold comprises a base 1, on which a power assembly for driving a device to perform clamping movement is arranged;

[0030] It also includes two clamping plates 5 symmetrically distributed inside the base 1, the insides of the two clamping plates 5 are connected to the rotating shaft 6 through the bearing, the opposite ends of the two rotating shafts 6 are fixedly connected to the mounting plate 8, and the side wall of the mounting plate 8 is provided with a clamping component 9 for clamping artificial bone brackets of different shapes;

The second moving frame 94 is slidably connected inside the three-way groove 92 and on both sides of the first moving frame 93. The second moving frame 94 is rotatably connected with a clamping half ring 95 inside. One end of the mounting block 91 away from the mounting plate 8 is fixedly connected to a limiting frame 96, and the limiting frame 96 is slidably connected to the first moving frame 93 and the second moving frame 94 respectively;

[0032] A limiting component 7 for fixing the rotating shaft 6 is provided at one end of the rotating shaft 6;

[0033] A supporting component for supporting the artificial bone support is arranged on the mounting plate 8 .

[0034] In addition, the first movable frame 93 and the second movable frame 94 have sealing properties in the interior of the three-way groove 92 and function as pistons.

[0035] The power assembly includes a slide groove 2. Two symmetrically distributed slide grooves 2 are opened at the upper end of the base 1. The insides of the two slide grooves 2 are rotatably connected with a bidirectional screw rod 3. One end of the bidirectional screw rod 3 passes through the base 1 and is fixedly connected to a driving motor 4.

[0036] For example, the driving motor 4 drives the bidirectional screw rod 3 to rotate inside the slide slot 2.

[0037] The interior of the slide groove 2 is slidably connected to the clamping plate 5 , and the outer wall of the bidirectional screw rod 3 is threadedly connected to the clamping plate 5 .

[0038] Furthermore, threaded movement occurs between the bidirectional screw rod 3 and the clamping plate 5 to control the position of the clamping plate 5 , and the slide groove 2 plays a role of limiting the position during the movement of the clamping plate 5 .

[0039] The limiting assembly 7 includes a rotating disk 71, one end of the rotating shaft 6 is fixedly mounted with the rotating disk 71, the interior of the rotating disk 71 is slidably connected to a limiting rod 72, the interior of the rotating disk 71 is fixedly connected to a return spring 73, one end of the return spring 73 is fixedly connected to a movable disk 74, and the interior of the clamping plate 5 is provided with a plurality of limiting holes 75 distributed in an annular manner.

[0040] Preferably, the clamping plate 5 is provided with a plurality of limiting holes 75 distributed in an annular shape, so that the limiting rod 72 in the rotating disk 71 can limit the rotating disk 71 at a plurality of positions.

[0041] The return spring 73 is arranged outside the limiting rod 72 , the limiting rod 72 is fixedly connected to the inside of the moving plate 74 , and the inner wall of the limiting hole 75 is slidably connected to the limiting rod 72 .

[0042] Specifically, the return spring 73 utilizes elasticity to control the movable disk 74 to move toward the position of the limiting hole 75 , the movable disk 74 drives the limiting rod 72 to move, and the limiting rod 72 is inserted into the limiting hole 75 to limit the rotating disk 71 .

[0043] The support assembly includes a through hole 10 . The mounting plate 8 is provided with a plurality of through holes 10 distributed in an array. An insertion rod 11 is slidably connected inside the through hole 10 , and one end of the insertion rod 11 is fixedly connected to a support plate 12 .

[0044] In this embodiment, the plurality of through holes 10 can be used to install the insertion rods 11 at different heights, thereby supporting brackets at different heights.

[0045] The outer surface of the insertion rod 11 is made of damping material, and a rubber plate is provided at the upper end of the support plate 12 to support the artificial bone support.

[0046] On the other hand, the outer surface of the insertion rod 11 is made of damping material, which can prevent the insertion rod 11 from easily falling off from the inside of the through hole 10, and the rubber plate plays a role in protecting the bracket.

[0047] Working principle: When the utility model is used, the driving motor 4 drives the bidirectional screw rod 3 to rotate inside the slide groove 2, and a threaded movement occurs between the bidirectional screw rod 3 and the clamping plate 5 to control the position of the clamping plate 5. According to the shape of the bracket, the distance between the clamping plates 5 is adjusted so that there is a certain gap between the bracket and the two first movable frames 93, and according to the shape of the bracket, the insertion rod 11 is inserted into the appropriate through hole 10, and the bracket is placed on the rubber plate of the support plate 12. When the driving motor 4 is turned on, the first movable frame 93 is slowly contacted with the bracket. When the surface of the bracket contacts the first movable frame 93, the first movable frame 93 squeezes the gas inside the three-way groove 92, and the second movable frame 94 moves toward the bracket. The clamping semi-ring 95 rotates to clamp the surface of the bracket. When the bracket contacts the second movable frame 94 first, the clamping process is far away from the above process;

[0048] The limiting rod 72 is pulled out from the limiting hole 75, and the rotating disk 71 is rotated to control the angle of the rotating shaft 6, and finally the processing angle of the bracket is controlled. When it is adjusted to a suitable angle, the limiting rod 72 is released, and the reset spring 73 uses its elasticity to control the movable disk 74 to move toward the position of the limiting hole 75. The movable disk 74 drives the limiting rod 72 to move, and the limiting rod 72 is inserted into the limiting hole 75 to limit the rotating disk 71.

[0049] 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.
