Abstract
Description
Technical Field
[0001] This utility model relates to the field of fracture reduction technology, specifically, it is a reduction and fixation device for transverse fractures of slender long bones. Background Technology
[0002] Long bone fractures are the most common type of fracture. Due to muscle traction and limb movement after a fracture, shortening deformity and rotational deformity are easily produced. Shortening deformity means that the bone length is shortened, and rotational deformity means that the broken bone is deviated. In this case, the broken bone must be reduced and the deformity corrected so that the alignment and force line are good after healing and does not affect the patient's quality of life. Otherwise, complications such as poor force line and malunion may lead to traumatic arthritis or osteoarthritis, which seriously affect the patient's limb function and quality of life.
[0003] Currently, when performing reduction of long bone fractures, the strong muscle forces make traction reduction difficult, often requiring the assistance of 3-4 traction medical personnel. The positioning of these 3-4 traction medical personnel surrounds the patient's long bone, leaving very little operating space for the surgeon. In this extremely limited operating space, the surgeon needs to accurately and quickly adjust the fracture alignment, further increasing the difficulty of traction reduction. At the same time, the reduction tools currently used in surgery are difficult to thread after reduction, which greatly affects the surgical operation during fracture reduction.
[0004] Therefore, in summary, there is an urgent need for a reduction and fixation device for transverse fractures of slender long bones that is simple in structure, easy to operate, can be maintained with one hand, saves manpower, effort and space, and can also traction and successfully reduce transverse fractures of long bones without affecting placement and fixation. Utility Model Content

[0023] Please see Figure 1-4 As shown, this device primarily addresses the problems encountered in existing methods for reducing long bone fractures, such as the difficulty in traction reduction due to strong muscle forces; the need for multiple surgeons during reduction, which consumes significant manpower and space; and the difficulty in inserting pins after reduction, affecting surgical procedures. To address these issues, a reduction and fixation device for transverse fractures of slender long bones is proposed. This device allows operators to perform reduction independently, saving manpower and reducing the workload of medical staff. It also facilitates pinning and fixation, and the pins can be easily removed without affecting plate fixation.
[0024] Based on this, the device includes a reduction slide rod 1 and a reduction traction device 2 that can slide on the reduction slide rod 1; and the reduction slide rod 1 has a cylindrical structure. When fixed, the doctor can flexibly adjust the reduction traction device 2 on the reduction slide rod 1 according to the specific situation, so as to achieve a better reduction effect on the fractured long shaft bone.
[0025] In this example, two repositioning traction devices 2 are provided and respectively installed on the repositioning slide rod 1. The two repositioning traction devices 2 on the repositioning slide rod 1 are arranged in a symmetrical structure. When in use, this arrangement enables the repositioning traction devices 2 on the repositioning slide rod 1 to fix the two ends of the long shaft bone after fracture, thereby realizing the traction repositioning of the long shaft bone.
[0026] The reset traction device 2 includes an integrally formed sliding ring 21, an operating traction rod 22, and a traction fixing plate 23.
[0027] Correspondingly, the sliding ring 21 is slidably mounted on the reset slide rod 1; and the diameter of the reset slide rod 1 is slightly smaller than the inner ring diameter of the sliding ring 21, so that the sliding ring 21 can slide and rotate in different directions (front and back, left and right) on the reset slide rod 1 (it can rotate 360° around the reset slide rod).
[0028] In addition, one end of the operating traction rod 22 is fixedly connected to the sliding ring 21, and the other end is fixedly connected to the traction fixing plate 23.
[0029] In this embodiment, the operating traction rod 22 is arranged in a Z shape, and the length of the end close to the reset slide rod 1 is greater than the length of the end close to the traction fixing plate; this setting facilitates the operator's grasping; correspondingly, the cross bar on the operating traction rod 22 also needs to ensure a certain length, so as to enable the traction rods at symmetric positions to cross, thus facilitating traction reduction and clamping fixation.
[0030] In this embodiment, the traction fixing plate 23 has a cuboid structure, and two identical hollow needle-passing guiding grooves 231 are provided on the traction fixing plate 23. Among them, the overall shape of the traction fixing plate looks like a structure in the shape of the Chinese character 'Ri'; correspondingly, the setting of the hollow needle-passing guiding grooves 231 on the traction fixing plate enables the bone needles to be fixed at both ends of the long bone fracture through the hollow needle-passing guiding grooves, so as to realize the traction of the fractured long bone; in addition, the long bone can also be subjected to semi-threaded screw compression through the hollow needle-passing guiding grooves, and after needle passing and compression, the traction fixing plate can be easily removed without affecting the fixation of the steel plate.
[0031] The usage method of the present utility model: During use, the surgeon himself can adjust the position of the traction fixing plate on the reduction traction device according to the specific conditions of the patient's long bone fracture (such as moving forward and backward on the reset slide rod, or rotating a corresponding angle on the reset slide rod), so as to achieve a better reduction effect; when the position of the traction fixing plate is determined, the bone needles are passed through the hollow needle-passing guiding grooves into both ends of the fracture, and compression is carried out through semi-threaded screws, so as to quickly perform transverse reduction on the fracture site; and after the needle passing and fixation, the traction fixing plate can be removed.
[0032] It should be noted that: The structure of the present utility model is simple and easy to use, convenient to carry and flexibly adjustable in multiple angles for reduction; in addition, the whole process can be independently completed by one person, which reduces the doctor's work burden, saves manpower and improves efficiency; at the same time, the setting of the hollow needle-passing guiding grooves on the fixing plate enables the needle passing and fixation to become easier and more accurate, and after needle passing, it can be easily removed without affecting the fixation of the steel plate.
[0033] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and supplements can still be made, and these improvements and supplements should also be regarded as the protection scope of the present utility model.
