Preferably, as shown in fig. 1 or 9, the rack is disposed on a side of the fixed plate or the movable plate facing away from the human body, the cover plate 700 is disposed on a side of the rack facing away from the human body, and the operation portion 830 is disposed on a side of the cover plate 700 facing away from the human body. That is, the first rack 810 is disposed on the front side of the thoracoabdominal fixation base plate 110 away from the human body, and the second rack is disposed on the rear side of the back fixation base plate 220 away from the human body.

The operation portion 830 is provided with a first limiting portion, the cover plate 700 is provided with a second limiting portion, and the operation portion 830 can move along the axial direction of the gear relative to the cover plate 700, so that the first limiting portion 831 and the second limiting portion 721 are combined to limit the rotation of the operation portion 830 and the gear, or the first limiting portion 831 and the second limiting portion 721 are separated.

It can be understood that, as shown in fig. 5, the first limiting portion is a snap projection; as shown in fig. 4, the second limiting portion 721 is a slot. When the operating portion 830 drives the gear to move toward the fixing plate along the axial direction of the gear shaft 821, the first limiting portion 831 can be clamped in the second limiting portion 721, at this time, under the action of the first limiting portion 831 and the second limiting portion 721, the operating portion 830 cannot rotate, the corresponding gear does not rotate any more, and the movable plate is fixed relative to the fixing plate; when the operation portion 830 drives the gear to move away from the fixing plate along the axial direction of the gear shaft 821, the first limiting portion 831 can be disengaged from the second limiting portion 721, the limiting effect of the first limiting portion 831 and the second limiting portion 721 is released, the operation portion 830 can drive the gear to rotate, and the movable plate and the fixing plate can move relatively.

In this embodiment, the operation portion 830 may be a knob.

Further, the abdomen-chest plate 120 and the back-back plate 210 are respectively provided with a sponge inner pad at a side close to the human body.

It can be understood that the inner sponge pad can reduce the pressing degree of the thoracolumbar vertebra fixator to the trunk, so that the thoracolumbar vertebra fixator of the embodiment is more comfortable to wear.

In summary, in the thoracolumbar fixator of the present embodiment, when in use, the shoulder straps are preferably used to connect the front upper chest fixing plate 500 and the back upper back fixing plate 400 with the retaining ring 300, so that the thoracolumbar fixator starts to be fixed by the force on the shoulders; then, the thoracolumbar fixator of the present embodiment can be fixed to the front and back of the body by connecting the buckle 300 between the thoracoabdominal movement plate 120 and the back movement plate 210 by a strap.

In the prior art, when a patient with thoracolumbar disease uses a common thoracolumbar fixator, the height and the width of the front adjusting fixing plate and the rear adjusting fixing plate are controlled by disassembling screws to find a range suitable for the body. However, the thoracolumbar vertebra fixator of the present embodiment can adjust the widths of the thoracoabdominal movable plate 120 and the dorsal movable plate 210 by the cooperation of the gear and the rack through the operation of the knob, and the thoracoabdominal fixed base plate 110 and the upper thoracic fixed plate 500 can be moved up and down by lowering the adjustment button to find the distance between the thoracic web 100 and the body which is most comfortable to fit, so that the difficulty of selecting the product size of the patient is avoided, the wearing times are reduced, and the body can be effectively relieved when the pain recurs.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
