In the description of the present invention, unless otherwise specified and limited, it is to be noted that the terms "mounted," "connected," and "connected" are to be interpreted broadly, and may be, for example, a mechanical connection or an electrical connection, a communication between two elements, a direct connection, or an indirect connection via an intermediate medium, and specific meanings of the terms may be understood by those skilled in the art according to specific situations.
As shown in fig. 1 to 3, the present application provides a humeral shaft fracture fixation device, which includes an upper arm fixation mechanism 1 and an anti-rotation splint 2, wherein the upper arm fixation mechanism 1 is used for fixing an upper arm, the anti-rotation splint 2 is mounted on the upper arm and the forearm, and the anti-rotation splint 2 is provided with an anti-rotation column 21; the anti-rotation splint 2 is positioned on the outer side of the upper arm and the inner side of the forearm.
The rotation-proof column 21 can prevent the arm from rotating, so the rotation-proof splint 2 can be a straight plate to fix the forearm; however, for better fixation of the upper arm and the forearm, it is preferable to design the anti-rotation splint 2 in an L-shape to fix the whole arm, so as to further prevent the elbow joint and the wrist joint from rotating, which is more effective. In order to meet the requirements of more patients, the threaded hole is designed at the bottom of the anti-rotation column 21, the anti-rotation column 21 is installed on the anti-rotation clamping plate 2 through a bolt, so that the anti-rotation columns 21 with different sizes can be replaced according to different patients, and the shape and the material of the anti-rotation column 21 can be customized. The anti-rotation column 21 is arranged on the anti-rotation splint 2, so that the anti-rotation splint plays a role in preventing the rotation and the displacement of the spiral fracture of the humeral shaft and is beneficial to the recovery of the fracture.
As shown in fig. 1, the upper arm fixing mechanism 1 includes a first clamp plate 11, a second clamp plate 12, a third clamp plate 13, and a fourth clamp plate 14. The first splint 11 is located on the inner side of the upper arm, the second splint 12 is located on the front side of the upper arm in the clockwise direction, the third splint 13 is located on the outer side of the upper arm, and the fourth splint 14 is located on the rear side of the upper arm, because the first splint 11 is the side of the arm close to the chest of the body after the arm is bent, the length is shortest, and the lengths of the second splint 12, the third splint 13 and the fourth splint 14 are sequentially lengthened.
In order to adapt to fracture with fracture lines close to shoulder joints, a rope ring 15 is arranged on the top of the second clamping plate 12, the third clamping plate 13 and the fourth clamping plate 14, and the second clamping plate 12, the third clamping plate 13 and the fourth clamping plate 14 are fixed on the shoulder parts by ropes passing through the rope ring 15. Since the first splint 11 is installed on the inner side of the upper arm with the top near the armpit, the loop 15 may not be provided on the top of the first splint 11. Owing to set up the becket 15, the rope passes second splint 12, it is possible to gather together the top of third splint 13 and fourth splint 14 with second splint 12 after third splint 13 and fourth splint 14 when tightening the rope, can reduce the fixed effect of exceeding the shoulder to the upper arm like this, consequently at second splint 12, the top of third splint 13 and fourth splint 14 all sets up two becket 15, the one end of rope passes second splint 12 in proper order like this, a becket 15 of third splint 13 and fourth splint 14, the other end of rope passes fourth splint 14 in proper order, another becket 15 on third splint 13 and the second splint 12, then fix the rope again, can reduce second splint 12, the concentration degree at third splint 13 and fourth splint 14 top. The upper arm fixing mechanism 1 is fixed by the rope loop 15, so that the problem of clamp plate gathering is prevented.
In order to make the recovery of the fractured humeral shaft faster, the upper arm fixing mechanism 1 and the anti-rotation splint 2 are mounted on the arm through belts and/or bandages and then the arm is hung on the neck through the hanging belt 3 by overcoming the gravity, so that the stress on the arm can be reduced, and the recovery is facilitated. In order to facilitate the patient to adjust the length of the sling 3 by himself, an adjusting buckle 31 can be arranged on the sling 3, so that the patient can adjust the sling 3 by himself with the other hand. The contact part of the hanging strip 3 and the anti-rotation splint 2 can be designed to be wider, and the stress is dispersed. The two ends of the hanging strip 3 can be directly connected with the two sides of the anti-rotation splint 2, and the anti-rotation splint can penetrate through the hanging strip 3, such as a triangle towel. The strap 3 may be separate from the anti-rotation splint 2 or the strap 3 may be fixedly attached to the anti-rotation splint 2.
The working process is as follows: the first splint 11, the second splint 12, the third splint 13 and the fourth splint 14 are mounted on the upper arm, the four splints are wound and fixed by a bandage, if the fracture line is close to the shoulder joint, a rope is wound around the armpit at the other side, and in order to prevent the armpit from being tightened, a cotton pad with a thick point can be padded at the armpit. The both ends of rope are knotted at the shoulder of fracture one side, then the one end of rope passes second splint 12 in proper order, a becket 15 on third splint 13 and the fourth splint 14, and another becket 15 on fourth splint 14, third splint 13 and the second splint 12 is passed in proper order to the other end of rope, then knot the rope and fix can. The first splint 11, the second splint 12, the third splint 13 and the fourth splint 14 are fixed by a band, then the rotation-preventing splint 2 is installed on the outer side of the upper arm and the inner side of the forearm, the rotation-preventing splint 2 is fixed by a band or a band, finally the sling 3 passes through the arm, the arm is hung on the neck, and the length of the sling 3 is adjusted by the adjusting buckle 31.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
