Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a fixing brace used for thoracic and lumbar vertebrae injuries and after operations. Background Art

[0002] If there are injuries in the chest and lumbar spine, surgery is required for correction and treatment. The joints after surgery are relatively fragile, and the patient cannot lie in bed for a long time. He should walk regularly and perform rehabilitation exercises accompanied by a caregiver. The standing limbs lack reinforcement, so a fixed brace is needed to assist from the front and back.

[0003] Most common braces are made of integrally injected plastic and are bound and connected by woven belts to provide support and reinforcement. Although the inner wall of the brace is smooth enough, it lacks an adjustment structure and is difficult to match for people with different waist shapes. It is quite inconvenient to walk in and uncomfortable to wear.

[0004] Now, a new type of fixation brace for thoracolumbar spine injury and post-surgery is proposed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a fixation brace for thoracic and lumbar spine injuries and post-surgery, so as to solve the problem that the curvature of the inner wall cannot be adjusted in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixation brace for thoracolumbar spine injury and postoperative treatment, comprising a left brace and a right brace, a right brace is arranged on the right side of the left brace, a card slot is arranged on the upper and lower parts of one side inside the left brace and the right brace, and an air bag is fixedly connected in the card slot, an inflation chamber is arranged in the air bag, a three-way pipe is fixed at the center of the inside of the left brace and the right brace, and connecting pipes are fixed at the top and bottom of the three-way pipe through the card slot respectively, a valve core is fixed at the center of the outside of the left brace and the right brace, a rubber plug is fixed on the upper part of the center of the outside of the left brace and the right brace, and air holes are arranged at the front and rear ends of the left brace and the right brace.

[0007] Preferably, the connecting pipe is connected to the airbag, and the side surface of the three-way pipe is fixedly connected to the valve core.

[0008] Preferably, three sets of transverse frames are welded to the side surfaces of the front and rear ends of the left and right braces, and a through slot is provided on one side of the upper part of the transverse frame, a gear is movably connected between the front and rear parts of the through slot, a connecting piece is movably inserted between one side of the transverse frame, and tooth grooves are provided on both sides of the top of the connecting piece, a screw hole is provided below one side of the transverse frame, and a bolt is meshed and connected in the screw hole, and threaded grooves are transversely provided on both sides of the bottom of the connecting piece

[0009] Preferably, one side of the bolt is embedded in the thread groove, and the bolt, thread groove and screw hole are arranged in concentric circles.

[0010] Preferably, the gear can rotate in situ in the through slot, and the bottom of the gear is engaged in the tooth slot.

[0011] Preferably, elastic bands are fixed to the front and rear ends of the tops of the left and right braces, and a step block is fixed above the elastic band, a short tube is fixed at the center of the side of the step block, and a second arc-shaped sleeve is fixed to the side of the short tube, a first arc-shaped sleeve is arranged in front and rear between the second arc-shaped sleeves, and holes are arranged on both sides of the inside of the first and second arc-shaped sleeves, and inserts are movably inserted between the holes.

[0012] Preferably, both sides of the plug are embedded in the socket, and the plug and the socket have the same curvature.

[0013] Preferably, the first arc-shaped sleeve, the second arc-shaped sleeve and the insert form a circular ring, and the elastic band is symmetrically fixed at two ends of the bottom of the building block.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the fixation brace for thoracolumbar vertebrae injury and post-surgery not only realizes the change of the curvature of the inner wall of the brace, realizes the reinforcement of the brace on both sides, but also realizes the prevention of the pad belt from collapsing;

[0015] (1) By fixing an air bag in the slot, the left brace and the right brace are respectively fixed on the two sides of the human body from both sides, and the rubber plug on the valve core is pulled out to connect the external air pump for inflation. The air is injected into the upper and lower air bags through the three-way pipe and the connecting pipe, so that the air bags expand in the slot, so that the inflated chamber of the air bags fits the surface of the human body, which can prevent the fixed brace from collapsing and increase comfort.

[0016] (2) By welding three sets of horizontal frames on the sides of the front and rear ends of the left brace and the right brace, after the left brace and the right brace are spliced, the bolts in the screw holes on the side of the horizontal frame are screwed so that the bolts push or pull the connecting pieces along the thread grooves. The connecting pieces inserted in the horizontal frame at the front and rear positions will mesh with the gears in the through grooves through the tooth grooves above, thereby adding some friction resistance to the connecting pieces and the horizontal frame, thereby preventing the left brace from being separated from the right brace. In addition, the spacing between the braces on both sides can be adjusted, thereby improving the wearing adaptability.

[0017] (3) The first arc sleeve is arranged in front and in the back between the second arc sleeves. The first arc sleeve and the second arc sleeve on both sides are pulled according to the circumference of the head. The distance between the first arc sleeve and the second arc sleeve is adjusted by the insert in the insert hole. Then, the structure is sleeved on the neck. The two sides are connected with elastic bands to adjust the positions of the blocks, so as to prevent the sling structure from loosening and prevent the brace from collapsing.
