Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a fast combined splint fixing device for bone trauma. Background Art

[0002] Bone trauma mainly refers to the damage to bones, bone joints and soft tissues around joints caused by external forces. Fracture is a type of bone trauma. When the force on the bones exceeds the maximum strength they can withstand, it may cause the continuity of the bones to be interrupted or partially broken. Patients often experience symptoms such as pain, limited movement, and swelling. After the human body's bones suffer a large impact, bone cracks or even fractures may occur.

[0003] After a fracture, it is often necessary to quickly fix the injured bone. Fixation can effectively prevent the fracture site from displacement, maintain the stability of the fracture end, avoid secondary injury to the fracture site, and prevent the fracture end from displacement again, thereby promoting the healing of the fracture. At the same time, fixation can reduce the pain at the fracture site and help the patient recover as soon as possible. However, during fixation, a corresponding fixing device is required. Currently, fixation is performed by combining a splint and a bandage. During fixation, the splint needs to be clamped and fixed piece by piece, and the assistance of another person is required; there are also methods that are connected into pieces and fixed with Velcro, but this type of fixation is not stable. At the same time, since the patient's limbs are not of equal diameter, they will not fit well on the patient's limbs, and the fixation is slow, and rapid fixation cannot be achieved.

[0004] Therefore, a new rapid combination splint fixation device for bone trauma is needed to solve these problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model discloses a fast combined splint fixation device for bone trauma, comprising: a plurality of outer splints 1, a connecting belt 2, and a contraction component 3; the outer splints 1 are connected to each other into a closed loop through the connecting belt 2, and the sides of the outer splints 1 on both sides are provided with a slide groove 13, and the connecting belt 2 passes through the slide groove 13 and connects to the outer splint 1 at the upper end; the upper end linear array of the upper outer splint 1 has a plurality of contraction components 3, and at the same time, the side of the outer splint 1 at the upper end is provided with a limiting groove 14, the limiting groove 14 extends to the uppermost end and is a through groove, and the connecting belt 2 is connected to the contraction component 3 through the limiting groove 14; the contraction and release of the connecting belt 2 are controlled by the contraction component 3 to control the mutual approach and distance between the outer splints 1 to achieve fixation and relaxation of the fracture;

[0022] Example 1

[0023] In this embodiment, the contraction component 3 includes: an outer shell 31, a bevel gear 32, a support block 36, and a two-way ratchet 38; the support block 36 is fixedly mounted on the upper end of the outer splint 1, and a rotating shaft 37 is rotatably connected between the support blocks 36; the support block 36 at one end is a hollow structure, and the two-way ratchet 38 is movably mounted inside, and the outer side of the two-way ratchet 38 is connected to a pair of mutually meshing bevel gears 32, one bevel gear 32 is fixedly connected to the outer side of the ratchet, and the other bevel gear 32 is rotatably connected to the upper end of the outer splint 1; a rotating rod 33 is installed in the middle of the bevel gear 32 on the outer splint 1; the connecting belt 2 is connected to the rotating shaft 37, and the outer shell 31 is covered by the outside of the bevel gear 32, the support block 36, and the two-way ratchet 38; the contraction component 3 can make the connecting belt 2 contract and drive the outer splint 1 gradually close to the injured person's affected limb. When in use, when clockwise The needle rotates the rotating rod 33, and the bevel gear 32 on the rotating rod 33 rotates accordingly, causing the other bevel gear 32 to rotate, thereby driving the rotating shaft 37 to rotate, causing the connecting belt 2 to shrink, and further driving the outer splint 1 to be tightened; when rotating in the opposite direction, the above process is reversed, and no further explanation is given here; at the same time, in this embodiment, considering that the rotating shaft 37 needs to be locked after rotation to prevent the connecting belt 2 from loosening and failing to fix the fracture, a two-way ratchet 38 is installed on the support block 36, and the clamping is achieved by the unidirectional action of the ratchet. However, since the entire device needs to be dismantled, the two-way ratchet 38 is used for fixing; since the reversing rod 34 of the two-way ratchet 38 is generally on the end face, and the bevel gear 32 is connected to the outside, the two sides of the reversing rod 34 are extended, and the extension rod 35 is extended, so that the steering can be smoothly performed during operation.

[0024] Example 2

[0025] In this embodiment, a reversing rod 34 is provided on the outer side of the bidirectional ratchet 38, and extension rods 35 are symmetrically provided on both sides of the reversing rod 34 and the extension rods 35 are arranged outside the outer shell 31; the reversing rod 34 can smoothly perform reversal, so that the connecting belt 2 can be tightened and released. At the same time, as described in Example 1, each part is exposed to the outside, which has certain safety hazards, so the outer shell 31 is used to cover the parts to ensure safety; however, in order to ensure reversal, the body shaping garment extends the reversing rod 34 outside the outer shell 31. When reversal is required, the extension rod 35 can be directly pressed. When tightening is required, the extension rod 35 on one side is pressed, and the extension rod 35 on the other side is extended; this method is easy to operate, simple in structure, and can quickly achieve fixation and relaxation;

[0026] At the same time, in this embodiment, based on the rotating rod 33 in Example 1, in order to facilitate the operation of the rotating rod 33, the rotating rod 33 is set to a T-shaped structure, the lower end is rotatably connected to the outer clamping plate 1, and the upper end extends out of the outer shell 31 and extends to both sides. It can be directly rotated when used. At the same time, in order to increase friction, anti-slip grooves can be added to the rotating rod 33 to increase friction.

[0027] Example 3

[0028] In this embodiment, the inner side of the outer splint 1 is filled with a plurality of springs 12 in an array, and the ends of the springs 12 are fixedly connected with the inner splint 11. The outer splint 1 is made of a hard material, such as a lightweight wooden board or a hard alloy material. These lightweight materials can reduce the burden on the affected part while fixing it, and reduce the patient's pain. The inner splint 11 is made of a soft material with a certain elasticity, such as a rubber material with a certain air permeability, such as natural rubber, styrene-butadiene rubber (SBR), etc. These rubber materials have good elasticity and wear resistance, and can allow gas to pass through the micropores in its structure, thereby achieving air permeability, and ensuring that the fixed part is air permeable; due to the elastic force of the spring 12, the inner splint 11 can be attached to the patient's affected part when there are gaps in the fixation, so that a good fit can be formed after fixation.

[0029] At the same time, in the present embodiment, a limiting clamp 21 is provided on the connecting belt 2 connecting the splints, and the limiting clamp 21 is located on the connecting belt 2 on the lower side of the movable outer splint 1, and limiting it here can well overcome the effect of gravity; the position of the splints on both sides can be adjusted and limited by the limiting clamp 21, so that when clamping, the limbs of patients in different situations can be adaptively adjusted, so that the outer splint 1 can be in a suitable position; the limiting clamp 21 is a clip in the prior art, such as the limiting buckle in the backpack strap; it belongs to the prior art and will not be explained in detail here.

[0030] The use principle of the utility model is: when in use, first rotate the rotating rod 33 to loosen the connecting belt 2, then put it on the patient's affected limb, and then adjust the position of the limiting clip 21 as needed to adapt to the thickness of the patient's limb, and then rotate the rotating rod 33 to shrink the connecting belt 2 so that the outer splint 1 is tightened. At this time, the inner splint 11 gradually approaches the injured person's affected limb and forms a fixation; after use, rotate the rotating rod 33 in the opposite direction to loosen the outer splint 1, and then it can be removed.

[0031] The preferred embodiments of the present invention disclosed above are only used to help explain the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to the specific implementation methods described.
