Description

Technical Field

[0001] The invention relates to an auxiliary medical device for orthopedics, in particular to a carbon fiber combined external fixator for auxiliary treatment of fractures. Background Art

[0002] During normal physical exercise, outdoor activities, walking, or cycling, people often damage or even break their leg bones due to carelessness. For patients with fractures, if the fracture ends are obviously displaced or misaligned, orthopedic surgery is required. If there is no obvious displacement of the fracture ends or the fracture is slightly displaced, it is necessary to reduce the fracture manually and then use external fixation with a fixation plate or splint. In either case, bone reduction is required, but the bones after reduction are not stable, so fixation is required. Fixation includes external fixation and open reduction fixation.

[0003] Manual reduction or external fixation usually uses splints, fixators or plaster braces for external fixation. There are various types of fixators, some for multiple parts of the body, but the height and weight of patients vary greatly, especially the thickness of arms or legs. Some of the existing fixators for arms or legs cannot be adjusted in size, which will cause certain pain to patients when fixing fractures of arms or legs of different thicknesses; some can be adjusted, but they are all adjusted by some elastic bands. For some patients with thicker arms or legs, the elastic bands will strangle the patient's injured part, causing slight blood circulation problems, which is not conducive to the patient's fracture recovery. In view of the above situation, in order to achieve fixation as soon as possible and relieve the patient's pain in time, we propose a carbon fiber combined external fixator for auxiliary treatment of fractures. Summary of the invention

[0004] The present invention provides a carbon fiber combined external fixator for auxiliary treatment of fractures, which solves the problems mentioned in the background art in the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: it includes a fixing component and a plurality of adjustment components, the fixing component surrounds the periphery of the patient's fractured arm or leg and is used to fix the fractured arm or leg bones, the plurality of adjustment components are detachably arranged on the outside of the fixing component and are used to adjust the diameter of the fixing component, the fixing component includes two splints one and six splints two, the splints one and the splints two are both arc-shaped plate-like structures, the two splints one and the six splints two are distributed in a circle, the two splints one are symmetrically arranged on the front side of the circle, and the two can be opened and closed and connected, the six splints two, three, and three are symmetrically arranged in groups on the middle and rear side of the circle, the splint one and the splint two are connected by a bendable connecting piece one, and the splint two and the splint two are connected to each other by a bendable connecting piece two, the adjustment component includes an adjustment block one and an adjustment block two, the adjustment block one and the adjustment block two are overlapped, and the overlapping position is adjustable, and the overlapping part of the adjustment block one and the adjustment block two is fastened by the cooperation of studs and flange nuts.

[0006] In order to facilitate the coordination of multiple adjustment components to achieve size adjustment of the fixed component, a fixed shaft is integrated at one end of splint one, and a protruding connecting shaft is integrated at the outer side of the middle part. The other end of splint one is connected to splint two through connecting piece one, a protruding connecting shaft is integrated at the outer side of one end of splint two, and the other end of splint two is connected to one end of the adjacent splint two through connecting piece two. Both connecting piece one and connecting piece two are made of soft and inelastic fabric.

[0007] In order to simply and quickly realize the size adjustment of the fixed component, the adjustment block one and the adjustment block two are both step-shaped structures. The non-overlapping end of the adjustment block one is a thick plate-shaped structure, and an arc-shaped concave ring buckle is arranged on the inner side. The radius of the ring buckle corresponds to the radius of the connecting shaft.

The other end of the second splint 8 is connected to one end of the adjacent second splint 8 through a connecting piece 2 11. Both the connecting piece 1 6 and the connecting piece 2 11 are made of soft and inelastic fabrics.

[0025] In order to simply and quickly realize the size adjustment of the fixed component, the adjustment block 14 and the adjustment block 27 are both step-shaped structures. The non-overlapping end of the adjustment block 14 is a thick plate-shaped structure, and an arc-shaped concave ring buckle 10 is processed on the inner side. The radius of the ring buckle 10 corresponds to the radius of the connecting shaft 3. A screw hole perpendicular to its axis is processed tangentially at the ring buckle 10, and a fastening screw 9 is screwed into the screw hole. The overlapping end of the adjustment block 14 is a long thin plate-shaped structure, and an upwardly protruding stud 12 is integrally provided. The non-overlapping end of the adjustment block 27 is a thick plate-shaped structure, and an arc-shaped concave ring buckle 10 is processed on the inner side.

[0026] In order to facilitate opening of the fixing assembly so that the patient can easily put it on, multiple connecting blocks 1 are rotatably installed on the fixing axis 2 of any splint 5, and the multiple connecting blocks 1 can be opened and closed on the fixing axis 2 of another splint 5, and a block-shaped lever 14 is integrally provided on the outer side of the connecting block 1.

[0027] Working principle:

[0028] Preparation: Step 1: First install multiple adjustment components on the outside of the fixed component: the buckles 10 of multiple adjustment blocks 1 4 are clamped on the connecting shaft 3 of the clamp plate 1 5 or the clamp plate 2 8 from top to bottom, and then the fastening screws 9 are respectively screwed downward to make the side walls of the fastening screws 9 close to the connecting shaft 3, and the connecting shaft 3 is pressed against the side of the buckle 10 to complete the fastening connection of the adjustment block 1 4, and the buckles 10 of multiple adjustment blocks 2 7 are clamped on the connecting shaft 3 of the clamp plate 2 8 or the clamp plate 1 5 from top to bottom, and then the fastening screws 9 are respectively screwed downward to make the side walls of the fastening screws 9 close to the connecting shaft 3, and the connecting shaft 3 is pressed against the side of the buckle 10 to complete the fastening connection of the adjustment block 2 7;

[0029] Step 2: overlap the adjustment block 1 4 and the adjustment block 2 7 in a state of one up and one down, first ensure a loose state when overlapping, and then tighten them with the stud 12 and the flange nut 13;

[0030] Usage process: Step 1: first open the connection block 1 by breaking the hand 14, so that the two splints 1 5 are opened, and the splint 1 5 and the splint 2 8, and the two splints 2 8 are connected by the connection piece 1 6 and the connection piece 2 11 made of soft inelastic cloth, so that the whole fixing assembly can be opened, and then the unfolded fixing assembly is wrapped around the patient's fractured arm or leg, and then the connection is completed by clamping multiple connection blocks 1 on the fixing shaft 2;

[0031] Step 2: Loosen the flange nut 13, and adjust the overlapping position of the adjustment block 1 4 and the adjustment block 2 7 through the relative position of the long hole 15 and the stud 12 according to the thickness of the patient's arm or leg. At this time, the connecting piece 1 6 and the connecting piece 2 11 are bent or folded, which reduces the diameter of the fixing component, so that the diameter of the fixing component is adjusted to fit the patient's arm or leg, ensuring that the splint 1 5 and the splint 2 8 can play the role of clamping and fixing the fractured bones of the patient's arm or leg;

[0032] In the actual adjustment process, not all overlapping positions of the adjustment block 1 4 and the adjustment block 2 7 need to be adjusted. The adjustment block 1 4 and the adjustment block 2 7 that need to be adjusted can be selected according to the wounds on the patient's arms and legs. The adjustment block 1 4 and the adjustment block 2 7 near the wound do not need to be adjusted to avoid the bent or folded connecting piece 1 6 or the connecting piece 2 11 from colliding with the wound and causing secondary damage to the patient's wound.
