Description

Technical Field

[0001] This utility model belongs to the field of auxiliary medical device technology, and in particular relates to an auxiliary fixation device for treating bone and joint trauma. Background Technology

[0002] After trauma, bones and joints need to be immobilized to restrict movement of the injured area, reduce stimulation of the injured area during movement, relieve pain and avoid secondary injury, such as fractures of the arm and leg, and provide a stable environment for the healing of the injured area. Immobilization can also reduce further bleeding caused by movement and prevent malunion.

[0003] Current fixation methods include splinting. When using splints, they are placed against the injured area and then wrapped with gauze. However, the tightness of the splint can affect the recovery of the injured area. If the fixation is too loose, the fixation effect will be poor, causing the fracture to shift again. If the fixation is too tight, it may cause compression, ischemia, skin ulceration, and other problems.

[0004] Since the tightness of the splint is achieved by wrapping it with gauze, the gauze is wrapped around the splint one circle at a time. If the wrapping force is too strong or too weak, it will affect the final tightness of the splint. If the tightness is not right after wrapping, the gauze needs to be loosened and wrapped again, which makes the adjustment of tightness quite troublesome. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary fixation device for treating bone and joint trauma, which facilitates the adjustment of the tightness of the fixation.

[0006] The aforementioned auxiliary fixation device for treating bone and joint trauma includes several splints. Each splint is provided with a connecting mechanism that allows them to be connected sequentially. The connecting mechanism includes several pull ropes. The splints are evenly provided with through holes along their length for the pull ropes to pass through. Several limiting blocks are fitted on the pull ropes between adjacent splints.

[0007] Furthermore, the mating surface of the clamp is provided with a protective layer.

[0008] Furthermore, the clamping plate is provided with four pieces.

[0009] Furthermore, the pull rope is provided with 3 ropes.

[0010] Furthermore, the limiting block has a spherical structure, and the diameter of the limiting block is smaller than the thickness of the clamping plate.

[0011] Furthermore, the limiting block has a ring structure, and the outer diameter of the limiting block is smaller than the thickness of the clamping plate.

[0012] Furthermore, a fixing block is fixed to the side of the clamp away from the contact surface, and a through hole for the pull rope to pass through is opened on the fixing block.

[0013] Furthermore, each clamp plate has two fixing blocks corresponding to each pull rope passing through.

[0014] Furthermore, the clamping plate is made of metal.

[0015] Furthermore, the pull rope is an ultra-high molecular weight polyethylene fiber rope.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a pull rope to fix the patient in place with a splint. Tightening the pull rope allows for easy adjustment of the splint's tightness, making operation convenient. The limiting block prevents changes in the spacing between adjacent splints during fixation, thereby reducing overall splint displacement and ensuring the splint's effective fixation of the patient.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0019] This embodiment describes an auxiliary fixation device for treating bone and joint trauma, such as... Figure 1 As shown, it includes several clamping plates 1, and the clamping plates 1 are provided with a connecting mechanism for sequential connection. The connecting mechanism includes several pull ropes 2. The clamping plates 1 are evenly provided with through holes for the pull ropes 2 to pass through along their length direction. Several limiting blocks 3 are fitted on the pull ropes 2 between adjacent clamping plates 1.

[0020] The splint 1 has a protective layer on its contact surface. The contact surface of the splint 1 is the side that comes into contact with the patient. The protective layer is made of rubber or sponge. The protective layer can prevent the splint 1 from coming into direct contact with the affected area, thereby reducing discomfort.

[0021] The clamping plate 1 is provided with 4 pieces, which can provide better clamping for the hands or legs and facilitates the installation in the correct position; of course, in some embodiments, the clamping plate 1 can also be two or three pieces.

[0022] The pull rope 2 is provided with 3 ropes, located at both ends and the middle of the splint 1 along its length, which can ensure the degree of fixation of the splint 1 by the pull rope 2. Of course, if the patient's affected area is relatively small and the required length of the splint 1 is relatively short, the pull rope 2 can also be provided with 2 ropes.

[0023] The limiting block 3 has a spherical structure and a hole for the pull rope 2 to pass through. The diameter of the limiting block 3 is smaller than the thickness of the splint 1. When the splint 1 is in contact with the patient, the limiting block 3 can be reduced from protruding too much and coming into contact with the patient. This ensures that the splint 1 is in close contact with the patient, thereby reducing the discomfort caused to the patient.

[0024] The limiting block 3 is a ring structure, and the outer diameter of the limiting block 3 is smaller than the thickness of the clamping plate 1. The ring structure of the limiting block 3 can also block the movement of two adjacent clamping plates 1.

[0025] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing block 4 is fixed on the side of the splint 1 away from the contact surface. The through hole through which the pull rope 2 passes is opened on the fixing block 4. The pull rope 2 is connected to the splint 1 through the fixing block 4, so there is no need to open a through hole on the splint 1. This can reduce the thickness of the splint 1, thereby reducing the overall weight, and also reduce the contact between the limiting block 3 and the patient.

[0026] Each clamp plate 1 has two fixing blocks 4 corresponding to each pull rope 2 passing through. Each clamp plate 1 has six fixing blocks 4, arranged in pairs for three different pull ropes 2 to pass through. This also reduces the overall volume of the fixing blocks 4, thereby reducing the weight of the fixing blocks 4.

[0027] The clamping plate 1 is made of metal. The thickness of the clamping plate 1 can be reduced by the fixing block 4, thereby ensuring its strength by using metal.

[0028] The pull rope 2 is made of ultra-high molecular weight polyethylene fiber rope, which has good strength, is not easily worn, and has a long service life; of course, in some embodiments, the pull rope 2 can also be nylon rope and / or aramid rope. The working principle and technical effects of this embodiment: When using this method to immobilize a patient's injured area, the splint 1 is placed against the patient, and then the two ends of the pull rope 2 are tied together. This tightens the pull rope 2, securing the splint 1 to the patient. The limiting block 3 prevents large changes in the gap between adjacent splints 1, reducing displacement of individual splints 1 and connecting all splints 1 into a single unit. This increases the difficulty of overall displacement of the splints 1, thus enhancing their immobilization effect on the patient. Using the pull rope 2 to immobilize the patient is simple to operate, and the tightness of the binding is easily adjustable. Of course, this method also has advantages in terms of application. When binding the hand or leg, the number of limiting blocks 3 between adjacent splints 1 can be increased or decreased, thereby adjusting the spacing between adjacent splints 1 so that the splints 1 fit more evenly on the patient's hand or leg. The gap between two adjacent splints 1 can ensure ventilation of the affected area, reducing some skin dampness and itching. In some embodiments, before fixing with splints 1, the affected area can be wrapped with gauze first, and then fixed with splints 1. This can prevent some impurities from contacting the affected area through the gap between splints 1, and can also prevent splints 1 and limiting blocks 3 from directly contacting the affected area.
