[0033] Based on this, in order to improve the technical problems in the related art that the splint is large in volume, affecting the wearing comfort of patients, and when fixing, more steps need to be completed, making it inconvenient to adjust after the patient's arm swells, the embodiment of the present application provides the following solutions.

[0034] Please refer to Figures 1 to 3, an embodiment of the present application provides an orthopedic splint installation and fastening device. The orthopedic splint 1 installation and fastening device includes: a splint 1 for fixing the arm; an elastic strap 11 provided on the splint 1 for connecting adjacent splints 1; two-end fasteners 2 provided on the splint 1 for fixing the position of the splint 1; a middle fastener 31 is also provided on the splint 1. The middle fastener 31 has the same structure as the two-end fasteners 2. A chute 3 is provided on the splint 1, and the middle fastener 31 is slidably arranged on the splint 1 through the chute 3.

[0035] With such a setting, during the process of a medical staff fixing the hand of a fracture patient, the splint 1 is fixed on the arm through the elastic strap 11. The two-end fasteners 2 respectively fix the elbow joint and the wrist joint of the forearm. At the same time, the middle fastener 31 is moved on the splint 1 through the chute 3 so that the middle fastener 31 is fixed at the fracture site. When fixing, the tightness of the fixing point should be appropriate, neither too tight to cause blood circulation disorders nor too loose to cause fixation failure. Usually, it is appropriate to be able to insert one or two fingers. In this way, by adjusting the fasteners, the tightness of the fixing point is ensured to be appropriate, avoiding blood circulation disorders caused by being too tight and fixation failure caused by being too loose. This design can reduce the discomfort of the patient and improve the wearing comfort. By adjusting the position of the middle fastener 31 through the chute 3, it can be ensured that the splint 1 directly acts on the fracture site, providing a more accurate fixing effect. This design can effectively prevent the displacement of the fracture end and promote the healing of the fracture.

[0036] In some embodiments, please refer to Figures 1 to 3 , the two-end fasteners 2 include a connection box 21 provided on the splint 1; a winding roller 22 rotatably arranged in the connection box 21; a fastening strap 23, one end of which is provided on the connection box 21, and the other end passes through the connection box 21 and is rotatably arranged on the winding roller 22; a rotating member 24 provided on the winding roller 22 for driving the winding roller 22 to rotate and tighten the fastening strap 23, thereby fixing the splint 1. The rotating member 24 includes: a rotating ring 245 provided on the winding roller 22, and a transmission groove 249 is annularly arranged on the rotating ring 245; abutting blocks 246 are annularly arranged on the rotating ring 245; a pressing block 247 is movably arranged in the rotating ring 245; transmission blocks 248 are annularly arranged on the pressing block 247, corresponding to the positions of the transmission grooves 249; a return spring 240, one end of which abuts against the rotating ring 245, and the other end abuts against the pressing block, for assisting the pressing block to rebound. A transmission plate 241 is also provided on the connection box 21. Connection grooves 243 are annularly arranged on the transmission plate 241, and a pressing spring 244 is arranged in the connection grooves 243. A wedge-shaped block 242 is arranged at the end of the pressing spring 244 away from the transmission plate 241.

[0037] With such a setting, during the process of rotating the rotating member 24 to rotate the winding roller 22 to tighten the fastening strap 23, by rotating the rotating ring 245, the rotating ring 245 drives the abutting block 246 to rotate. During the rotation of the abutting block 246, it presses against the wedge-shaped block 242 in the connecting groove 243. The wedge-shaped block 242 squeezes the compression spring 244 inward. When the rotation angle is greater than the length of the wedge-shaped block 242, the wedge-shaped block 242 rebounds under the action of the compression spring, and the rotation of the abutting block 246 is restricted by the wedge-shaped block 242, thereby achieving the tightening of the fastening bandage. During the process of loosening the tightening of the fastening bandage, by pressing the pressing block 247, the pressing block 247 drives the transmission block 248 to slide in the transmission groove 249, and the transmission block 248 compresses the wedge-shaped block 242 completely into the connecting groove 243, canceling the restriction of the wedge-shaped block 242 on the abutting block 246, facilitating the overall rotation of the rotating ring 245. In this way, by rotating the rotating ring 245, the tightening of the bandage can be achieved. The operation process is simple, and medical staff can complete the operation with one hand, and the other hand can be used to stabilize the patient's limb or other operations, improving the flexibility and efficiency of the operation. By pressing the pressing block 247, the transmission block 248 compresses the wedge-shaped block 242 completely into the connecting groove 243, canceling the restriction on the abutting block 246, and the rotating ring 245 can rotate back easily, realizing the rapid relaxation of the bandage. This design makes the relaxation operation simple and fast, avoiding the problem that it is difficult to untie due to the too tight winding of the strap in the traditional fixing method. By the rotation angle of the rotating ring 245, the tightness of the bandage can be precisely controlled to ensure that the tightness at the fixing point is appropriate. This design can avoid blood circulation disorders caused by over-tightening or fixing failure caused by over-loosening, improving the stability of the fixation, and can flexibly adjust the tightness of the bandage according to the limb shape, size and swelling degree of different patients to ensure that each patient can obtain the best fixation effect.

[0038] In some embodiments, please also refer to Figures 2 to 3 , a guiding block 26 is arranged on the pressing block 247, a guiding groove 261 is opened at a position corresponding to the guiding block 26 on the rotating ring 245, and a rotating handle 25 is arranged on the abutting block 246.

[0039] With such a setting, the guiding block 26 slides within the guiding groove 261, which can precisely control the movement trajectory of the pressing block 247, ensuring the stability and consistency of the pressing operation. This design avoids the possible deviation or shaking of the pressing block 247 during the operation, improving the accuracy of the operation. The guiding block 26 slides within the guiding groove 261, which can precisely control the movement trajectory of the pressing block 247, ensuring the stability and consistency of the pressing operation. This design avoids the possible deviation or shaking of the pressing block 247 during the operation, improving the accuracy of the operation. The guiding block 26 slides within the guiding groove 261, which can precisely control the movement trajectory of the pressing block 247, ensuring the stability and consistency of the pressing operation. This design avoids the possible deviation or shaking of the pressing block 247 during the operation, improving the accuracy of the operation.

[0040] The implementation principle of the splint installation and fastening device for orthopedics in the embodiment of the present application is as follows: During the process of a medical staff fixing a fracture patient's hand, the splint 1 is fixed on the arm through the elastic band 11, and the two end fasteners 2 respectively fix the elbow joint and the wrist joint of the forearm. At the same time, the middle fastener 31 is moved on the splint 1 through the sliding groove 3 so that the middle fastener 31 is fixed at the fracture site. When fixing, the tightness of the fixing point should be appropriate, neither too tight to cause blood circulation disorders nor too loose to cause fixing failure. Usually, it is appropriate to be able to insert one or two fingers. During the process of rotating the rotating part 24 to rotate the winding roller 22 to tighten the fastening band 23, by rotating the rotating ring 245, the rotating ring 245 drives the abutting block 246 to rotate. During the rotation of the abutting block 246, it presses the wedge-shaped block 242 within the connecting groove 243. The wedge-shaped block 242 squeezes the abutting spring 244 inward. When the rotation angle is greater than the length of the wedge-shaped block 242, the wedge-shaped block 242 rebounds under the action of the compression spring, and the abutting block 246 is restricted from rotating back by the wedge-shaped block 242, thus realizing the tightening of the fastening bandage. During the process of loosening the tightening of the fastening bandage, by pressing the pressing block 247, the pressing block 247 drives the transmission block 248 to slide within the transmission groove 249. The transmission block 248 compresses the wedge-shaped block 242 completely into the connecting groove 243, canceling the restriction of the wedge-shaped block 242 on the abutting block 246, facilitating the overall rotation of the rotating ring 245.

[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
