Description
A wood structure that can improve the fixation effect of distal radius fractures The present invention relates to a wood support structure that can improve the fixation effect of distal radius fractures, and in particular to a wood support structure that can effectively improve the fixation effect of distal radius fractures, has a modular comb component that is environmentally friendly and multifunctional, and can be replaced by either hand for convenient use. Among orthopedic patients, many patients' hands (including the palm, wrist, and the area below the wrist) need to be fixed for a period of time using traditional wrist splints while waiting for recovery. Referring to Figures 6A, 6B, 7A, 7B, and 8, a conventional wrist splint system includes: A pair of wooden frame elements 81, which are long, rigid structures that are not easily deformed. The covering portion 82 is a sheet-like member having an upper edge 821, a lower edge 822, two side edges 823, a receiving space 824, two thumb openings 825, and at least one fixing portion 826. The receiving space 824 is used to accommodate the secondary wooden frame member 81 and a user's hand 91; the two thumb openings 825 are used to allow a thumb 911 of the hand 91 to pass through; and the at least one fixing portion 826 allows the covering portion 82 to enclose and secure the hand 91. When wearing the device, the thumb 911 of the hand 91 first passes through one of the two thumb openings 825 of the covering portion 82, and then the covering portion 82 covers the hand 91 (at least covering the palm, wrist, and the area below the wrist) and the secondary wooden frame element 81. Furthermore, the secondary wooden frame element 81 is not easily deformed, thereby effectively securing the hand 91. However, referring to FIG. 7B , when facing a fracture 931 of the distal radius 93 (wrist deformed due to a fall), the secondary wooden frame element 81 is located in the center position and just presses on the surgical wound. In addition, it fails to limit the rotation of the fixed wrist, resulting in a poor fixation effect on the distal radius fracture. In addition, when the hand is restored and no longer needs to be fixed, the wrist wooden fixation device can only be discarded and has no other use, which is very wasteful. In view of this, it is necessary to develop a technology that can solve the above-mentioned conventional shortcomings. The present invention aims to provide a wood support structure that can improve the fixation effect of distal radius fractures. The structure has the advantages of effectively improving the fixation effect of distal radius fractures, being environmentally friendly and multifunctional, and being interchangeable for left and right hand use. Specifically, the present invention aims to solve the following problems: when the distal radius fracture is located, the wood support frame element, not only presses against the surgical wound due to its central position, but also fails to restrict wrist rotation, resulting in poor fixation of the distal radius fracture. Furthermore, when the hand is healed and no longer needs to be fixed, the wood support fixation device for the wrist must be discarded, becoming useless and wasteful. The technical means to solve the above problem is to provide a wood structure that can improve the fixation effect of distal radius fractures, which includes: A first comb structure comprises a first upper surface, a first lower surface, a first comb portion, and two engaging recesses; the first comb portion is located between the first upper surface and the first lower surface; the two engaging recesses are symmetrical, and each of the two engaging recesses comprises two upper sliding grooves and a lower sliding groove; the two upper sliding grooves are recessed in the first upper surface; the lower sliding groove is recessed in the first lower surface and adjacent to the two upper sliding grooves; A second comb structure having a second upper surface, a second lower surface, a second comb portion, and an engaging pawl portion; the second comb portion is located between the second upper surface and the second lower surface, and the engaging pawl portion has two upper sliding pawls and a lower sliding pawl; the two upper sliding pawls extend from the second upper surface respectively; the lower sliding pawl extends from the second lower surface and is adjacent to the two upper sliding pawls; the engaging pawl portion can slide into one of the two engaging recesses, and slide and fix in the corresponding two upper sliding grooves and the lower sliding groove, thereby forming a modular comb assembly; and A covering portion is a sheet-like structure having an upper edge, a lower edge, two side edges, a receiving space, two thumb openings and at least one fixing portion; the receiving space is used to accommodate the combined comb assembly and a hand of a user; the two thumb openings are used to allow one thumb of the hand to pass through; and the at least one fixing portion is used for the covering portion to wrap around and fix the hand. The above-mentioned objects and advantages of the present invention can be more clearly understood from the following detailed description of the selected embodiments and the accompanying drawings. The present invention is described in detail with reference to the following embodiments and accompanying drawings: Referring to Figures 1A, 1B, 1C, 1D, 2, and 3, the present invention is a splint structure capable of improving the fixation effect of distal radius fractures, comprising: A first comb structure 10 comprises a first upper surface 11, a first lower surface 12, a first comb portion 13, and two engaging recesses 14. The first comb portion 13 is located between the first upper surface 11 and the first lower surface 12. The two engaging recesses 14 are symmetrical, and each of the two engaging recesses 14 has two upper sliding grooves 141 and a lower sliding groove 142. The two upper sliding grooves 141 are recessed in the first upper surface 11; the lower sliding groove 142 is recessed in the first lower surface 12, adjacent to the two upper sliding grooves 141. A second comb structure 20 comprises a second upper surface 21, a second lower surface 22, a second comb portion 23, and an engaging claw portion 24. The second comb portion 23 is located between the second upper surface 21 and the second lower surface 22. The engaging claw portion 24 comprises two upper sliding claws 241 and a lower sliding claw 242. The two upper sliding claws 241 extend from the second upper surface 21, respectively. The lower sliding claw 242 extends from the second lower surface 22 and is located adjacent to the two upper sliding claws 241. The engaging claw portion 24 can slide into one of the two engaging recesses 14 and be fixed in the corresponding upper sliding grooves 141 (see Figures 4A, 4B, and 4C) and the lower sliding groove 142 (see Figures 5A and 5B), thereby forming a modular comb assembly. The covering portion 30 is a sheet-like structure having an upper edge 31, a lower edge 32, two side edges 33, a receiving space 34, two thumb openings 35, and at least one fixing portion 36. The receiving space 34 is used to accommodate the combined comb assembly and a user's hand 91; the two thumb openings 35 are used to allow a thumb 911 of the hand 91 to pass through; and the at least one fixing portion 36 allows the covering portion 30 to enclose and secure the hand 91. In practice, the first comb structure 10 can be a shell-shaped structure. The engaging protruding claw portion 24 slides into one of the two engaging recesses 14 (refer to FIG. 1B ), so that the combined comb assembly can be used by the user's left hand. The engaging protruding claw portion 24 slides into the other of the two engaging recesses 14, so that the combined comb assembly can be used by the right hand of the user. The at least one fixing portion 36 can be a Velcro structure. To wear the comb, the thumb 911 of the hand 91 is first passed through one of the two thumb openings 35 of the covering portion 30. The covering portion 30 then covers the hand 91 (at least the palm, wrist, and the area below the wrist) and the combined comb assembly. The combined comb assembly's resistance to deformation allows for a good fixation of the hand 91. Of course, the combined comb assembly can also be sewn onto the covering portion 30 . The key point is that, referring to Figure 2, when facing a fracture 931 of the distal radius 93 (wrist deformity caused by a fall), the second comb structure 20 can be tilted to one side (as shown in Figures 1B and 1C, both of which are diagrams of different angles of tilt to the left) to avoid the fracture 931 (surgical wound) due to its ability to accommodate left or right hand gripping. Furthermore, the first comb structure 10 can increase the palmar coverage area, thereby limiting wrist rotation and effectively improving the fixation effect of the distal radius fracture. Furthermore, when not in use, the cover 30 can be detached from the combined comb assembly. The combined comb assembly can then be held with the second comb structure 20, effectively transitioning from a hand-holding function to a hair-combing function. This eliminates the need to discard the comb and ensures it remains idle, providing a multi-functional solution. Furthermore, the second comb structure 20 can also be used independently, with the second comb section 23 performing the hair-combing function. Referring to FIG. 5C , the lower sliding latch pawl 242 can be forcibly pulled out of the lower sliding latch groove 142 (for example, withdrawn from the right side of the two engaging recesses 14), or an arbitrary object 92 (such as a thin rod) is inserted into the lower sliding latch groove 142 to press down on the lower sliding latch pawl 242 so that the lower sliding latch pawl 242 can be withdrawn and then slid into the left side of the two engaging recesses 14, thereby achieving a change from right-hand operation to left-hand operation. The advantages and effects of this case can be summarized as follows: [1] Effectively improve the fixation effect of distal radius fractures. When facing the fracture of the distal radius, the second comb structure can be tilted to one side to avoid the fracture because it can be held by the left or right hand. And because the first comb structure can increase the palmar coverage area, it can limit the rotation of the fixed wrist, thereby having a better fixation effect on the distal radius fracture. Therefore, it effectively improves the fixation effect of the distal radius fracture. [2] The modular comb assembly is environmentally friendly and multifunctional. When the modular comb assembly of the present invention is combined with the covering portion to cover the hand, the modular comb assembly can utilize the characteristic of not easily deforming to produce a good fixing effect on the hand. When the hand does not need to be fixed, the covering portion can be separated from the modular comb assembly, and then the modular comb assembly can be held with the second comb structure. The modular comb assembly then changes from the fixing function of "fixing the hand" to the combing function of "combing the hair". Therefore, the modular comb assembly is environmentally friendly and multifunctional. [3] The combined comb assembly can be switched between right and left hands, making it very convenient. When the engaging protruding claw portion slides into the right side of the two engaging recesses, the combined comb assembly can be used by the user's right hand. When the engaging protruding claw portion slides into the left side of the two engaging recesses, the combined comb assembly can be used by the user's left hand. Therefore, the combined comb assembly can be switched between right and left hands, making it very convenient. The above is merely a detailed description of the present invention through preferred embodiments. Any simple modifications and changes made to the embodiments do not depart from the spirit and scope of the present invention. 10: First comb structure 11: First upper surface 12: First lower surface 13: First comb portion 14: Engaging recess 141: Upper sliding groove 142: Lower sliding groove 20: Second comb structure 21: Second upper surface 22: Second lower surface 23: Second comb portion 24: Engaging claw portion 241: Upper sliding claw 242: Lower sliding claw 30, 82: Covering portion 31, 821: Upper edge 32, 822: Lower edge 33, 823: Side edge 34, 824: Accommodating space 35, 825: Thumb opening 36, 826: Fixing portion 81: Secondary wooden frame element 91: Hand 911: Thumb 92: Any object 93: Distal radius 931: Fracture FIG. 1A is a schematic diagram of an exploded view of the modular comb assembly of the present invention.
