Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a reduction and fixation orthopedic device for orthopedics. Background Art
[0002] For fracture orthopedic surgery, it is usually through surgical methods after fracture, using steel plates, screws, etc. for internal fixation, so that the fracture ends are restored to the normal anatomical structure, and then using plaster or splints for external fixation to prevent displacement and promote fracture healing. In the prior art, the patent document with the publication number CN113797025B discloses a medical auxiliary device for orthopedic fracture plaster treatment, which includes a protection mechanism, a cutting mechanism, a bending part shearing mechanism A, and a bending part shearing mechanism B. Among them, the cutting mechanism cooperating with the protection mechanism effectively cuts the straight part of the plaster cylinder protecting the limb fracture and the corresponding inner lining gauze, and the protection mechanism protects the body surface from being cut by the cutting mechanism that overcuts the plaster; this invention cuts and disassembles the plaster at the fracture of the patient through the cooperation of the protection structure and the cutting mechanism, effectively protecting the patient's body surface from being cut by the cutting mechanism due to the personal factors of the operator of the cutting mechanism, with high safety, and at the same time having low requirements for the cutting and disassembly experience of the operator for plaster removal, being suitable for different operators to use.
[0003] Using plaster orthosis can match well with the shape of the limb. When the fracture heals or at regular intervals, the plaster can be disassembled. During the use process, limb swelling often occurs at the part where the plaster is applied, and the plaster cannot be adjusted with the swelling of the limb, resulting in great pain for the patient. In severe cases, it is necessary to remake the plaster mold, increasing the frequency of plaster replacement. Based on this, the existing method of using a plaster mold for orthopedic orthosis has the problem of inconvenient adjustment of the gap with the limb surface. During the patient's recovery period, when symptoms such as swelling, itching, stuffiness, and pressure sore pain occur, the orthopedic device cannot be finely adjusted to relieve the pain, and it is very inconvenient to use. Summary of the Invention
[0004] The purpose of the present invention is to solve the problem in the prior art that the method of using a plaster mold for orthopedic orthosis has the problem of inconvenient adjustment of the gap with the limb surface, and to propose a reduction and fixation orthopedic device for orthopedics.
[0005] To achieve the above object, the present invention adopts the following technical solutions: An orthopedic reduction and fixation orthopedic device for orthopedics, comprising an outer shell and a shaping sheet. The outer shell is of a two-piece structure, including upper and lower half shells. The upper and lower half shells are buckled together by a buckle to form a cylindrical structure with both ends open. A first arc plate and a second arc plate are respectively rotatably installed in the half shells. A pressing plate is arranged on the side surface of the half shell. One side of the shaping sheet is fixedly connected to the first arc plate, and the other side of the shaping sheet is clamped and fixed by the pressing plate. The shaping sheet is made of multiple layers of gauze stacked together. By pulling the side of the shaping sheet away from the first arc plate, the shaping sheet can be wrapped around the surface of the limb. Gypsum slurry is injected into the shaping sheet. When the water in the gypsum slurry volatilizes and hardens, the shaping sheet containing the gypsum slurry forms a non-flexible shaping shell, and the limb is fixed and orthopedically corrected through the shaping shell.
[0006] Preferably, pressing strips are rotatably installed on the inner sides of the first arc plate and the second arc plate. Arc-shaped waist grooves are opened at both ends of the half shell. The two ends of the second arc plate extend into the arc-shaped waist grooves. A binding strap is fixedly installed on the outer surface of the second arc plate. A fixing ring is fixedly installed on the surface of the half shell. After the binding strap passes through the fixing ring, it is fixedly adhered through the magic tape on the surface of the binding strap to tighten the binding strap, prompting the second arc plate to slide along the arc-shaped waist groove, so that the pressing strip abuts against the shaping sheet, so that the shaping sheet can better fit the surface of the limb.
[0007] Preferably, an adjusting bolt is threadedly installed on the surface of the half shell. The second arc plate slides along the arc-shaped waist groove, and the outer surface of the second arc plate is in sliding contact with the end of the adjusting bolt. Under the blocking action of the adjusting bolt, the second arc plate is pushed to flip and rotate towards the first arc plate side. The pressing strip on the second arc plate presses on the surface of the shaping sheet, and the shaping sheet is tensioned by the acting force of the pressing strip on the second arc plate, so that the pressing strip on the first arc plate also presses on the surface of the shaping sheet. By screwing in or out the adjusting bolt, the flipping angle of the second arc plate can be adjusted.
[0008] Preferably, a guiding groove is opened on the side of the half shell away from the first arc plate. The end of the pressing plate can be slidably placed in the guiding groove. An installation groove is opened on the side of the half shell away from the second arc plate. An abutting bolt is threadedly installed on the surface of the half shell, and the end of the abutting bolt extends into the installation groove. When the upper and lower half shells are buckled together, the installation groove on the lower half shell is aligned with the guiding groove on the upper half shell, and the pressing plate can be slidably installed from the installation groove into the guiding groove, and the pressing plate is abutted by tightening the abutting bolt.
[0009] The inner side of the pressing plate is fixedly installed with serrated protrusions. One side of the shaping piece away from the first arc-shaped plate extends into the guiding groove. When the pressing plate slides in the guiding groove, the serrated protrusions can penetrate into the shaping piece, and the shaping piece is tensioned by the traction of the serrated protrusions. Unscrewing the fastening bolt can separate the upper and lower shaping shells from each other.
[0010] Preferably, the shaping piece includes an inner layer, an interlayer, and an outer layer. The inner layer, the interlayer, and the outer layer are all multi-layer gauze structures. The interlayer is fixed between the inner layer and the outer layer in a corrugated shape. Grouting channels are formed between the interlayer and the inner layer and between the interlayer and the outer layer. A plurality of grouting pipes are fixedly installed on the surface of the outer layer, and the grouting pipes are communicated with the grouting channels. Gypsum slurry can be input into the grouting channels through the grouting pipes.
[0011] Preferably, after the binding straps are loosened, the pressing force of the pressing strips on the first arc-shaped plate and the second arc-shaped plate on the shaping piece is released at the same time.
[0012] After the fastening bolt is unscrewed, the two shaping shells located in the first arc-shaped plate and the second arc-shaped plate can move away from each other, increasing the gap between the shaping shell and the limb. After the fastening bolt is screwed in, a traction force is applied to one side of the shaping piece away from the first arc-shaped plate, increasing the inner cavity radian of the shaping shell. By screwing in or unscrewing the fastening bolt, the orthopedic orthosis can adjust the size of the gap between the shaping shell and the limb surface, relieve the pain caused by limb swelling, and ensure that the orthopedic orthosis adheres to the limb so as to continue orthopedic protection after the swelling disappears.
[0013] The present invention has the following beneficial effects:
[0014] 1. For the orthopedic orthosis proposed by the present invention, by providing a housing composed of two half-shells buckled together and installing two shaping pieces in the housing, after injecting gypsum slurry into the two shaping pieces respectively, a rigid shaping housing is made. The limb is fixed and orthopedically corrected through the shaping housing, which can well fit the surface of the limb. The upper and lower shaping housings can be separated, providing conditions for adjusting the gap between the shaping housing and the limb surface, and meeting the use requirement of relieving pain by adjusting the gap.
[0015] 2. For the orthopedic orthosis proposed by the present invention, by arranging the first arc-shaped plate and the second arc-shaped plate in the half-shell, after the shaping piece is pulled, the pressing strip is pressed against the surface of the shaping piece by the rotation of the first arc-shaped plate and the second arc-shaped plate, so that the shaping piece can well wrap the surface of the limb. Here, it refers to the upper and lower shaping pieces, which respectively wrap the upper half area and the lower half area of the limb surface. Since the second arc-shaped plate can slide along the arc-shaped waist groove, the pressing strip on the second arc-shaped plate can be adjusted in the up and down direction, so that the area of the shaping piece wrapping the upper half area or the lower half area of the limb surface is increased as much as possible, achieving a better shaping and orthopedic effect.
[0016] 3. The orthopedic orthosis device proposed by the present invention, by providing a shaping sheet, before injecting the gypsum slurry, the shaping sheet is relatively soft and is convenient to be laid on the surface of the limb. During the process of pressing one side of the shaping sheet by the pressing plate, the shaping sheet is tractioned with different forces on the side away from the first arc plate, so as to prompt the shaping sheet to deform according to the shape of the limb, ensure that the manufactured shaping shell better fits the surface of the limb, make the orthopedic operation more convenient, and thus achieve the effect of convenient installation.
[0017] 4. The orthopedic orthosis device proposed by the present invention, by providing serrated protrusions on the inner side of the pressing plate and pressing the pressing plate by the tightening bolt, the movement of the pressing plate can provide a traction force for the shaping sheet. It should be emphasized that the upper and lower shaping shells are held tightly on the surface of the limb, which is achieved under the combined action of the first arc plate, the second arc plate and the above-mentioned traction force. When the strap is untied and the pressing effect of the pressing strip on the shaping shell is eliminated, after the tightening bolt is screwed out, the two shaping shells located in the first arc plate and the second arc plate can move away from each other. Or, after the tightening bolt is screwed in, a traction force is applied to the side of the shaping sheet away from the first arc plate, so as to increase the inner cavity radian of the shaping shell and increase the gap between the shaping shell and the limb. By screwing the tightening bolt in or out, the orthopedic orthosis device can adjust the size of the gap between the shaping shell and the surface of the limb, relieve the pain caused by limb swelling, and ensure that the orthopedic orthosis device adheres to the limb for continuous orthopedic protection after the swelling disappears.

Detailed implementation mode
[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0030] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0031] Refer to Figures 1 - 10 , an orthopedic reduction and fixation orthopedic device for orthopedics, including an outer shell and a shaping piece 1. The outer shell is a two-piece structure, and the outer shell includes two upper and lower half shells 2. The two upper and lower half shells 2 are fastened together by a buckle to form a cylindrical structure with open ends at both ends. A first arc plate 3 and a second arc plate 4 are respectively rotatably installed inside the half shells 2. A pressing plate 5 is arranged on the side of the half shell 2. One side of the shaping piece 1 is fixedly connected to the first arc plate 3, and the other side of the shaping piece 1 is clamped and fixed by the pressing plate 5.
[0032] Among them, the shaping piece 1 is made of multiple layers of gauze stacked together. For details, refer to Figure 9 , the shaping piece 1 includes an inner layer 15, an interlayer 16 and an outer layer 17. The inner layer 15, the interlayer 16 and the outer layer 17 are all multi-layer gauze structures. The interlayer 16 is fixed in a corrugated shape between the inner layer 15 and the outer layer 17. Grouting channels 18 are formed between the interlayer 16 and the inner layer 15, and between the interlayer 16 and the outer layer 17. Refer to Figure 3, a plurality of grouting pipes 19 are fixedly installed on the surface of the outer layer 17. The grouting pipes 19 are communicated with the grouting channel 18, and gypsum slurry can be input into the grouting channel 18 through the grouting pipes 19.
[0033] Specifically, as Figure 4 shown, pressing strips 6 are rotatably installed on the inner sides of the first arc plate 3 and the second arc plate 4. The shape of the pressing strips 6 can be customized according to the shape of the limb 20.
[0034] Arc-shaped waist slots 7 are opened at both ends of the half shell 2. The two ends of the second arc plate 4 axially extend into the arc-shaped waist slots 7. A binding strap 8 is fixedly installed on the outer surface of the second arc plate 4. A fixing ring 9 is fixedly installed on the surface of the half shell 2. After the binding strap 8 passes through the fixing ring 9, it is adhesively fixed through the magic tape on the surface of the binding strap 8 to tighten the binding strap 8, prompting the second arc plate 4 to slide along the arc-shaped waist slot 7. Refer to Figure 8 , tighten the binding strap 8, the second arc plate 4 flips downward, and at the same time slides along the arc-shaped waist slot 7, so that the lower side of the second arc plate 4 extends downward.
[0035] Among them, as Figure 6 shown, an adjusting bolt 10 is threadedly installed on the surface of the half shell 2. The second arc plate 4 slides along the arc-shaped waist slot 7, and the outer surface of the second arc plate 4 is in sliding contact with the end of the adjusting bolt 10. Under the blocking action of the adjusting bolt 10, the second arc plate 4 is pushed to flip and rotate toward the first arc plate 3 side. The pressing strip 6 on the second arc plate 4 presses on the surface of the shaping piece 1, and the shaping piece 1 is tensioned by the acting force of the pressing strip 6 on the second arc plate 4, so that the pressing strip 6 on the first arc plate 3 also presses on the surface of the shaping piece 1.
[0036] In this embodiment, as Figure 1 、 Figure 2 、 Figure 3 shown, a guiding groove 11 is opened on the side of the half shell 2 away from the first arc plate 3. The end of the pressing plate 5 can be slidably placed in the guiding groove 11. An installation groove 12 is opened on the side of the half shell 2 away from the second arc plate 4. An abutting bolt 13 is threadedly installed on the surface of the half shell 2. The end of the abutting bolt 13 extends into the installation groove 12. When the upper and lower half shells 2 are buckled together, the installation groove 12 on the lower half shell 2 is aligned with the guiding groove 11 on the upper half shell 2. The pressing plate 5 can be slidably installed from the installation groove 12 into the guiding groove 11, and the pressing plate 5 is abutted by tightening the abutting bolt 13.
[0037] As Figure 7 shown, a serrated protrusion 14 is fixedly installed on the inner side of the pressing plate 5. One side of the shaping piece 1 away from the first arc plate 3 extends into the guiding groove 11. When the pressing plate 5 slides in the guiding groove 11, the serrated protrusion 14 can pierce into the shaping piece 1 and tension the shaping piece 1 through the serrated protrusion 14.
[0038] Reference Figure 8 On the side of the traction and shaping piece 1 away from the first arc-shaped plate 3, the shaping piece 1 can be wrapped around the surface of the limb 20. Gypsum slurry is injected into the interior of the shaping piece 1. When the moisture in the gypsum slurry volatilizes and hardens, the shaping piece 1 containing the gypsum slurry forms a non-flexible shaping shell.
[0039] It should be noted that, as Figure 10 shown, when the shaping piece 1 has not been injected with gypsum slurry, the shaping piece 1 is relatively soft. The shaping piece 1 adheres to the surface of the limb 20. Hold the edge of the shaping piece 1 and pull the shaping piece 1 with the acting forces of F1, F2, and F3. The shaping piece 1 can deform according to the shape of the limb 20 and wrap around the surface of the limb 20. This makes the inner cavity of the shaping shell after the injection of gypsum slurry and hardening more conform to the shape of the limb 20. Taking Figure 6 as an example, at Figure 6 points B and C in
[0040] pull the shaping piece 1. The upper and lower shaping pieces 1 are wrapped around the surface of the limb 20, and then use the pressing plate 5 to press the edge of the shaping piece 1;
[0041] During use, as Figure 6 shown, when wearing the orthopedic orthosis proposed by the present invention, tighten the upper and lower straps 8, so that the second arc-shaped plate 4 flips and slides along the arc-shaped waist groove 7. The pressing strip 6 on the second arc-shaped plate 4 presses on the surface of the shaping piece 1. At the same time, pull the shaping piece 1 at points B and C, so that the first arc-shaped plate 3 flips and the pressing strip 6 on the first arc-shaped plate 3 presses on the surface of the shaping piece 1, so that the upper and lower shaping pieces 1 wrap around the limb 20 and are located in the middle position of the outer housing. Then screw in the tightening bolt 13, and tension the shaping piece 1 through the serrated protrusion 14 on the pressing plate 5. Finally, input gypsum slurry into the grouting channel 18 through the grouting pipe 19. Wait for the gypsum slurry to dry and harden to form a shaping shell.
[0042] By providing an outer housing composed of two half shells 2 buckled together and installing two shaping pieces 1 inside the outer housing. Before injecting the gypsum slurry, the shaping piece 1 is relatively soft and is convenient to be laid on the surface of the limb 20. During the process of using the pressing plate 5 to press one side of the shaping piece 1, pull the shaping piece 1 on the side away from the first arc-shaped plate 3 with different forces, so as to promote the shaping piece 1 to deform according to the shape of the limb 20, ensuring that the produced shaping shell better fits the surface of the limb 20. After injecting gypsum slurry into the two shaping pieces 1 respectively, a hard shaping outer shell is made, and the limb 20 is fixed and orthopedically treated through the shaping outer shell, which can well fit the surface of the limb 20.
[0043] By arranging a first arc-shaped plate 3 and a second arc-shaped plate 4 inside the half shell 2, after the traction shaping piece 1 is pulled, by means of the rotation of the first arc-shaped plate 3 and the second arc-shaped plate 4, the pressing strip 6 is pressed against the surface of the shaping piece 1, so that the shaping piece 1 can be well wrapped around the surface of the limb 20. Here, it refers to the upper and lower shaping pieces 1, which respectively wrap the upper half area and the lower half area of the surface of the limb 20. Since the second arc-shaped plate 4 can slide along the arc-shaped waist groove 7, the pressing strip 6 on the second arc-shaped plate 4 can be adjusted in the up and down directions and press the shaping piece 1, so that the area of the shaping piece 1 wrapping the upper half area or the lower half area of the surface of the limb 20 is increased as much as possible. In this way, the contact surface between the manufactured shaping shell and the limb 20 is larger, and a better shaping and orthopedic effect is achieved.
[0044] During use, if symptoms such as swelling, itching, stuffiness and pressure sore pain occur in the limb 20, the binding strap 8 is loosened. Because the area of the shaping piece 1 that is not injected with gypsum slurry is relatively soft and can be bent at will, after the binding strap 8 is loosened, the first arc-shaped plate 3 and the second arc-shaped plate 4 can both be turned by a certain angle. At this time, the pressing force of the pressing strip 6 on the first arc-shaped plate 3 and the second arc-shaped plate 4 on the shaping piece 1 is released at the same time, and the upper and lower shaping shells can move away from each other, so that a gap is generated between the shaping shell and the surface of the limb 20;
[0045] If the gap between the shaping shell and the surface of the limb 20 needs to be further increased, it is adjusted by screwing out the tightening bolt 13. Specifically, after the tightening bolt 13 is screwed out, as Figure 6 shown, the pressing plate 5 on the left side moves upward, the pressing plate 5 on the right side moves downward, and the traction shaping piece 1 at B and C retracts into the outer shell body. The two shaping shells located inside the first arc-shaped plate 3 and the second arc-shaped plate 4 can move away from each other, increasing the gap between the shaping shell and the limb 20;
[0046] If you don't want the orthopedic orthosis to be too loose on the surface of the limb 20, loosen the binding strap 8 and screw the tightening bolt 13 in. As Figure 6 shown, the pressing plate 5 on the left side moves downward, the pressing plate 5 on the right side moves upward, and the traction shaping piece 1 moves at B and C, applying a traction force to the side of the shaping piece 1 away from the first arc-shaped plate 3. The upper and lower shaping shells are deformed, increasing the inner cavity radian of the shaping shell. However, in the area between L-L, the upper and lower shaping shells are still clamped on the surface of the limb 20. This design expands the gap between the shaping shell and the surface of the limb 20 by increasing the inner cavity radian of the shaping shell and always keeps the shaping shell clamping and shaping the limb 20, which is applicable to the situation where the orthopedic orthosis is installed at the joint of the patient to avoid the influence of joint movement on treatment.
[0047] The orthopedic orthosis device proposed by the present invention is provided with serrated protrusions 14 on the inner side of the pressing plate 5. By pressing the pressing plate 5 with the tightening bolt 13, the movement of the pressing plate 5 can provide a traction force for the shaping piece 1. It should be emphasized that the upper and lower shaping shells are held tightly on the surface of the limb 20, which is achieved by the combined action of the first arc-shaped plate 3, the second arc-shaped plate 4 and the above-mentioned traction force. When the strap 8 is untied to eliminate the pressing effect of the pressing strip 6 on the shaping shell, after the tightening bolt 13 is screwed out, the two shaping shells located in the first arc-shaped plate 3 and the second arc-shaped plate 4 can move away from each other. Or, after the tightening bolt 13 is screwed in, a traction force is applied to the side of the shaping piece 1 away from the first arc-shaped plate 3, so that the inner cavity curvature of the shaping shell increases, and the gap between the shaping shell and the limb 20 is increased. By screwing the tightening bolt 13 in or out, the orthopedic orthosis device can adjust the size of the gap between the shaping shell and the surface of the limb 20, relieve the pain caused by the swelling of the limb 20, and ensure that the orthopedic orthosis device is attached to the limb 20 so as to continue orthopedic protection after the swelling disappears.
[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
