Detailed Description
As shown in fig. 1 to 5, a vertebra bone-knitting device comprises a first mounting plate 1, a second mounting plate 7, a fracture part fixing claw 4 and a fixing plate device 13, wherein the second mounting plate 7 is arranged below the first mounting plate 1, screw holes 11 are respectively arranged in the middle parts of the first mounting plate 1 and the second mounting plate 7, a first screw 10 is inserted into the screw hole 11 on the first mounting plate 1, a second screw 8 is inserted into the screw hole 11 on the second mounting plate 7, the fixing plate device 13 is arranged between the first mounting plate 1 and the second mounting plate 7, the fixing plate device 13 comprises a first fixing plate 2, a second fixing plate 3, a third fixing plate 5 and a fourth fixing plate 6, the first fixing plate 2 is arranged below the first mounting plate 1, the second fixing plate 3 is arranged below the first fixing plate 2, the fourth fixing plate 6 is arranged above the second mounting plate 7, a third fixing plate 5 is installed above the fourth fixing plate 6, a fracture part fixing claw 4 is installed between the second fixing plate 3 and the third fixing plate 5, a plurality of air holes 9 are formed in the circumference of the fracture part fixing claw 4, the fixing plate device 13 comprises two surfaces, a movable surface 15 is arranged on one surface, close to the vertebra, of the fixing plate device 13, a fixing surface 14 is arranged on one surface, far away from the vertebra, of the fixing plate device 13, a hinge 12 is installed between the first fixing plate 2 and the movable surface 15 of the second fixing plate 3, and a hinge 12 is installed between the third fixing plate 5 and the movable surface 15 of the fourth fixing plate 6.
The first fixing plate 2 and the second fixing plate 3 can rotate relatively to each other through the rotational connection between the first fixing plate 2 and the second fixing plate 3 through the hinge 12, so as to provide a bending space for the bending of the spine.
The third fixing plate 5 and the fourth fixing plate 6 are rotatably connected through the hinge 12, so that the third fixing plate 5 and the fourth fixing plate 6 can rotate relatively to provide a bending space for the bending of the spine.
Since both sides of the fracture fixation claw 4 are in the shape of a curved claw, the fracture fixation claw 4 can tightly grasp the fracture of the spine.
Because first fixed plate 2 and the first mounting panel 1 formula structure as an organic whole first fixed plate 2 and first mounting panel 1 are more firm.
Through fourth fixed plate 6 and second mounting panel 7 formula structure as an organic whole, fourth fixed plate 6 is more firm with second mounting panel 7.
The working principle of the invention is as follows: the fracture part fixing claws 4 of the invention are used for grasping the bone-knitting position of the vertebra, the first screws 10 and the second screws 8 are driven into the vertebra, after the bone-knitting is completed, a doctor can release the medicine from the air holes 9, after the bone-knitting is successful, when a patient needs to bend and relax the vertebra, only the vertebra is slightly bent, the bending angle is generated between the first fixing plate 2 and the second fixing plate 3, and the bending angle is generated between the third fixing plate 5 and the fourth fixing plate 6, and the two bending angles can be used for bending the vertebra.
