Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] See also Figure 1-6 As shown, an orthotic device for treating a distal radioulnar joint comprises an upper splint 1, a rib 2, a lower splint 5 and a hand splint 7. The upper splint 1, the lower splint 5 and the hand splint 7 are movably connected via the rib 2. The rib 2 on the surface of the upper splint 1 is rotatably connected to the rib 2 on the surface of the lower splint 5.

[0032] It also includes a slide rail 8, which is installed on the surface of the lower clamping plate 5. The surface of the slide rail 8 is provided with a slide groove 11, and the rib 2 is slidably connected in the slide groove 11;

[0033] The surface of the rib 2 is provided with a connecting plate 14, the surface of the connecting plate 14 is rotatably connected to a pull tab 6, and the surface of the pull tab 6 is fixedly connected to an adjustment strap 4;

[0034] A limit block 13 is provided on the surface of the rib 2 to prevent the rib 2 from falling out of the chute 11. A clamping block 15 is slidably connected to the surface of the limit block 13 via a spring, and a fixing mechanism is provided on the surface of the clamping block 15.

[0035] The surface of the slide 11 is provided with a fixing groove 9, and the fixing groove 9 is provided with a plurality of fixing grooves;

[0037] When working, first splice the two ribs 2, and then insert one end of the rib 2 into the slide groove 11, so that the rib 2 can slide back and forth in the slide groove 11, and then install the upper splint 1, the lower splint 5 and the hand splint 7 on the patient's arm. At this time, by sliding the rib 2 back and forth, the length between the upper splint 1 and the lower splint 5 can be adjusted to a length that matches the patient's arm, and then fixed by the fixing mechanism. Quick adjustment can be achieved by sliding the rib 2, and then the card block 15 is driven by the spring to be stuck in the fixing groove 9, avoiding the use of screws to fix the two splints, solving the problem of screws being stripped and twisted after a long time of use, which is inconvenient in the later stage. When the clamp 15 is in use, it is inconvenient to disassemble and assemble by means of screw positioning, which is time-consuming and labor-intensive. When disassembly is required, the clamp 15 is pulled up, which will drive the support rod 20 to move. When the clamp 15 moves to the limit position, the spring drives the support rod 20 to pop out, so that the support rod 20 fits on the surface of the slide rail 8, limiting the clamp 15. At this time, it is convenient for medical staff to slide the rib 2. After the rib 2 is adjusted to the appropriate position, the clamp 15 is pressed downward, so that the support rod 20 retracts into the through groove 23 and tends to extend outward, fitting on the inner wall of the empty groove 18, thereby further fixing the clamp 15. Finally, the angle between the upper splint 1 and the lower splint 5 is fixed by installing the adjustment strap 4 on the surface of the pull tab 6.

[0038] The surface of the rib 2 is fixedly connected to a limit block 13, and the surface of the slide 11 is provided with a mounting groove 16.

The surface of the limit block 13 is slidably connected to a clamping bead 12 via a spring, and a clamping groove is provided in the slide 11 at a position relative to the clamping bead 12;

[0039] During operation, the rib piece 2 can be disassembled through the installation groove 16 opened on the surface of the slide groove 11. The installation groove 16 opened on the side can prevent the rib piece 2 from separating from the slide rail 8 during adjustment. At the same time, the card bead 12 cooperates with the spring to bounce in the card groove, which can achieve a damping effect, improve the adjustment feel of medical staff, and provide feedback to facilitate adjustment by medical staff.

[0040] A positioning groove 21 is provided on the surface of the support rod 20, and the positioning groove 21 is in contact with the side wall of the empty groove 18. An arc corner is provided on the surface of the limit block 13. Anti-slip pads are fixedly connected to both sides of the block 15 and the empty groove 18, and the anti-slip pads are made of rubber. During operation, the support rod 20 can be limited by the "V"-shaped positioning groove 21, and the support rod 20 can be positioned to make the sliding more stable. At the same time, the friction force can be increased by the anti-slip pad, which further improves the fixing effect between the support rod 20 and the empty groove 18, and avoids slipping when medical staff pull the block 15.
