Description
Technical Field
The invention belongs to the field of medical supplies, and relates to a fracture fixing device, in particular to a lower limb fracture fixing traction device.
Background
When the lower limb is fractured or dislocated, the phenomena of angle formation, shrinkage displacement, instability after dislocation and reduction and the like often occur under the action of the natural contraction force of the muscles of the lower limb, and in order to resist the contraction of the muscles, traction treatment is often adopted clinically, and the lower limb is required to be always kept in a certain position during traction. The original Thomas and Brownian frames are characterized in that a bandage is wound on a metal frame, the lower leg of a patient is placed on the bandage, a traction pulley is designed at the tail end of the metal frame, and a traction weight is connected with the far end of a fracture through a traction rope and the traction pulley, so that the purposes of resisting muscle strength, achieving the treatment of fracture or joint reduction are achieved, a good treatment effect is achieved, and the traditional Chinese medicine composition is widely used in clinic to date. With the continuous development of medical technology, because original Thomas and Brown's frames are welded and formed by iron materials, corrosion resistance is poor, rust is easy, storage and preservation are inconvenient, stainless steel materials are changed to be processed, the problems of rust and corrosion resistance are well solved, traction frames are improved, a plurality of novel lower limb traction frames are produced, a plurality of defects are overcome, and the following defects still exist through long-time clinical observation: (A) The height of the traction frame is fixed, so that the traction frame is suitable for patients with medium stature, and when the patients with overhigh stature or children use the traction frame, the posture is obviously uncomfortable, and the traction and treatment effects are affected. (B) The traction pulley is fixed in position, the traction angle is restricted to be constant, and the traction treatment requirements of different fracture patients cannot be met. (C) The affected limb is placed on the cloth support wound by the bandage, the thigh depends on the surrounding bandage to resist traction resistance, the surrounding bandage is shifted and deformed after long-time traction, local soft tissues are pressed, the traction frame is directly clamped and pressed on the popliteal fossa and the perineum, local discomfort is caused, and the patient often adjusts the whole position by himself, so that traction and treatment effects are affected.
The prior art also discloses a lower limb traction frame which consists of a main frame, a lifting frame and a folding frame. The lifting frame is sleeved and connected with the lifting frame, can be stretched up and down, is fixed through a lifting lock, and can adjust the height of the lifting frame according to the needs of patients with different heights in all age groups; the main frame is provided with a transverse arc-shaped concave supporting plate which is bent inwards longitudinally, so that the device is suitable for comfortable placement of traction limbs and convenient for cleaning and disinfection; the folding frame is connected with the main frame through a steering gear shaft on the folding frame, can move up and down in a sliding groove of the main frame when in a vertical position with the main frame, can change a traction angle and reduce the gravity center, can turn 90 degrees towards the direction of the main frame through the steering gear when in a vertical position with the main frame and is in a highest position, is stacked in parallel with the main frame, has small occupied space and is convenient to care and store; the design of a plurality of traction pulleys with bearings and a support frame can realize multi-angle and compound traction, reduce traction loss and keep the traction balanced. Although the tractor is optimized and reformed in the prior art, the tractor in the prior art is still not portable enough, is not convenient to use, and is not suitable for emergency situations.
With the development of industries such as traffic and construction in China and the like and the aging of population, patients suffering from traffic injuries, building fall injuries and senile osteoporosis fracture are increased year by year. Meanwhile, modern war is accompanied by development and use of high-energy weapons, so that war wounded persons often have fractures under various wounded factors. In trauma emergency treatment, temporary fixation of fractures and handling of wounded persons are one of the most important and critical technologies, and the TCCC committee in the united states has also recognized splint fixation and related technology as an important technological means suitable for battle and non-battle emergency personnel. How to fix the fracture quickly and effectively, and plays a role in rapidly transferring and curing the wounded. The conventional fracture emergency fixing device is used for fixing the splint, has the advantages of convenient operation, wide application range and the like, particularly has a good fixing effect on temporary fixing of limb fracture, relieves pain, stops bleeding and reduces the incidence rate of fat embolism syndrome in the process of delivering the injured person, thereby avoiding secondary injury.
However, the fracture fixation device used for emergency treatment in China is still in a backward state worldwide. Most of the traditional wood splints for first-aid fracture fixation are inconvenient to carry, have poor fixation effect, are used together with bandages and triangular towels, are time-consuming and labor-consuming in the whole process, cannot achieve good fixation effect, and cannot be used for fixation of open type crushed fracture combined with soft tissue injury; while the coiled splint has plasticity, the fixing strength is greatly reduced, once the used triangular towel and the bandage are not firmly fixed, secondary damage is easily caused in the carrying process, and the injury is aggravated; most importantly, the device does not have the function of traction along the fracture part, and can not relieve local pain of wounded, such as long transportation time of the traumatized or crushed fracture wounded, fracture deformity healing or secondary displacement, so that the chance of surgical treatment can be lost, and lifelong disability and regretta are left for patients and wounded.
