Description

Technical Field

[0001] This utility model relates to the field of orthopedic splint technology, specifically to an orthopedic splint installation and fastening device. Background Technology

[0002] With the progress and development of the times and the continuous innovation of medical methods, when patients receive treatment for bone trauma, it is necessary to install splints to fix the position of the bones in the injured area. The splints fix the position of the bone injury to prevent bone displacement and avoid secondary injury.

[0003] When patients are injured and their bones are broken, the chances of leg bone injury are often high, requiring the use of splints. However, the installation and fixation of splints are very inconvenient, and existing splints have limited functions and simple structures, which cannot properly fix and adjust the injured person's leg. Some of the structures are redundant, which seriously affects the patient's wearing experience. Therefore, we have proposed an orthopedic splint installation and fastening device.

[0025] Furthermore, the fastening adjustment structure consists of an interlocking ring of arc-shaped fixing part 3 and arc-shaped fixing part 4, with the ends of arc-shaped fixing part 3 and arc-shaped fixing part 4 corresponding to the bidirectional threaded rod 2. The fastening adjustment structure ensures that the clamping force can be adjusted by the injured person at the bone injury site, facilitating rapid recovery of the bone injury site.

[0026] Furthermore, the main body of the arc-shaped fixing component 3 is an arc-shaped plate 9. The two ends of the arc-shaped plate 9 are provided with connecting blocks 11 distributed symmetrically on both sides, and the sidewalls of the connecting blocks 11 are provided with mating holes 12. The inner side of the arc of the arc-shaped plate 9 is provided with a rubber pad 10, and the outer side of the arc of the arc-shaped plate 9 is welded with three equally spaced sliding rods 13. The sliding rods 13 are welded with a limiting arc plate 14 away from the axial end of the arc-shaped plate 9. The arc-shaped plate 9 is more likely to fit the outer contour of the limb, while the rubber pad 10 can improve the wearing experience, prevent abrasion to the injured person's skin, and improve the wearing stability.

[0027] Furthermore, the main body of the arc-shaped fastener 24 is an arc-shaped plate 25, and the two ends of the arc-shaped plate 25 are provided with connecting blocks 27 distributed symmetrically. The connecting blocks 27 are provided with two mating grooves 23 distributed symmetrically at the two arc-shaped shaft ends of the arc-shaped plate 25. The mating grooves 23 are provided with the arc-shaped plate 19 and the connecting block 11 for sliding. The side wall of the connecting block 27 is provided with mating holes 28. The inner side of the arc-shaped plate 25 is provided with rubber pads 26, and the outer side of the arc-shaped plate 25 is welded with three sliding rods 29 distributed symmetrically. The shaft ends of the sliding rods 219 away from the arc-shaped plate 215 are welded with limiting arc plates 20. The sliding rods 219 and the sliding rods 13 are distributed symmetrically. The mating grooves 23 facilitate the tightening of the annular staggered structure of the arc-shaped fastener 3 and the arc-shaped fastener 24, thus realizing the adjustable wearing size.

[0028] Furthermore, the bidirectional threaded rod 2 has an axisymmetric structure, and the middle structure of the bidirectional threaded rod 2 is a hexagonal block 21. The hexagonal block 21 has threads 22 at both ends, and the threads 22 at both ends rotate in opposite directions. The threads 22 at both ends are respectively connected to mating hole 12 and mating hole 18. The threads 22 at both ends of the bidirectional threaded rod 2, which rotate in opposite directions, can simultaneously drive the arc-shaped fixing part 3 and the arc-shaped fixing part 4 to move relative to or in opposite directions, so as to realize the adjustable wearing size.

[0030] Working Principle: Install the orthopedic splint installation and fastening device correctly according to the diagram. When using this device to immobilize an injured person's leg, first determine the actual size of the injured person's leg and the location of the injury. The connecting cylinder 1, a key connecting component, is a hollow cylinder. The radially penetrating fitting port 7 on the side wall of the cylinder accommodates the fastening adjustment structure. Three equidistant sliding holes 8 perpendicular to it provide sliding tracks for slide rod 13 and slide rod 19, ensuring structural stability. The connecting cylinder 1 can effectively adjust... The overall length of the device is designed to fit different parts of the injured person's leg, avoiding inconvenience caused by excessive length and greatly improving the wearing experience. The fastening and adjustment structure is the core of achieving precise fixation. It consists of two interlocking arc-shaped fixing parts, 3 and 4. The inner side of the arc plate 9 of the arc-shaped fixing part 3 fits against the injured person's leg, and the rubber pad 10 can both cushion pressure and prevent abrasion to the injured person's skin, and increase friction to improve wearing stability. The three sliding rods 13 on the outside pass through the sliding holes 8 of the connecting cylinder 1, and the limiting arc plate 14 prevents slippage. Rod 13 disengages. The arc plate 25 of arc-shaped fastener 24 is similar in structure to arc plate 9. Its inner rubber pad 26 also provides protection and stability. The groove 23 is cleverly designed to facilitate relative sliding between arc-shaped fastener 3 and the groove. The two work together to closely conform to the contour of the injured person's leg and adapt to changes in thickness. The bidirectional threaded rod 2 plays a key adjustment role. The hexagonal block 21 in the middle facilitates operation with tools. The threads 22 at both ends, with opposite directions of rotation, respectively engage with the mating hole 12 of arc-shaped fastener 3 and the mating hole 218 of arc-shaped fastener 24. Next, when it is necessary to tighten the splint, by rotating the hexagonal block 21, the bidirectional threaded rod 2 uses the thread transmission principle to make the arc-shaped fixing part 1 3 and the arc-shaped fixing part 2 4 move relative to each other. The annular interlocking structure gradually tightens, precisely applying clamping force to the injured person's bone injury. The force can be adjusted according to the actual situation of the injured person. Conversely, rotating in the opposite direction can loosen the splint. This flexible adjustment mechanism can not only ensure effective fixation of the bone injury and promote rapid recovery, but also avoid the problems of being too tight or too loose. It greatly improves the wearing experience of the injured person and provides an efficient and comfortable fixation solution for orthopedic treatment.
