[0002] Distal radius fracture refers to a fracture within 3 cm of the distal articular surface of the radius. It is one of the most common fractures in clinical practice and is more common in middle-aged and elderly patients with osteoporosis. Common distal radius fractures are generally divided into: extension fractures, flexion fractures, Barton fractures, etc. Traditional Chinese medicine splints are a traditional fracture treatment method. They use splints made of materials such as wood chips or cardboard to fix the injured limb to prevent the displacement of the fracture site and promote fracture healing.

[0003] However, the above-mentioned method of using a small Chinese medicine splint to treat fractures also has some difficult problems to solve, such as early external fixation after fracture reduction, the wrist joint of the affected limb needs to maintain a specific position, and the wrist joint is placed in a flexed or extended position for external fixation to prevent the fracture from displacing again. If a splint is used for external fixation, a specific model must be selected first, or it must be specially made to force the affected limb to be placed in the required position. In the middle and late stages, it is necessary to release the forced position of the affected limb, restore the wrist joint to a neutral position or a functional position for external fixation, and perform functional exercises to prevent joint stiffness, especially to prevent joint stiffness in a special position. Otherwise, serious sequelae will occur. This means that the external fixation device needs to be replaced or remade, which is cumbersome and complicated.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The present invention and its embodiments are described below. This description is not restrictive and the actual embodiments are not limited to the following. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.

[0021] The inventor has found that the current Chinese medicine splint method for treating fractures also has some difficult-to-solve problems, such as early external fixation after fracture reduction, the wrist joint of the affected limb needs to maintain a specific position, and the wrist joint is placed in a flexed or extended position for external fixation to prevent the fracture from shifting again. If a splint is used for external fixation, a specific model must be selected first, or it must be specially made to force the affected limb to be placed in the required position. In the middle and late stages, the forced position of the affected limb must be released, the wrist joint must be restored to a neutral or functional position for external fixation, and functional exercises must be performed to prevent joint stiffness, especially to prevent joint stiffness in a special position. Otherwise, serious sequelae will occur. This means that the external fixation device needs to be replaced or remade, which is cumbersome and complicated. More importantly, the remake is difficult to match with the front fixation splint.

[0022] Based on the above findings, the present application proposes a traditional Chinese medicine small splint wrist-metacarpal joint external fixation device, which includes an upper fixing plate, a lower fixing plate, an upper clamping airbag, a lower clamping airbag and a side splint for fixing the joint of a patient with a distal radius fracture. The upper fixing plate and the lower fixing plate are arranged opposite to each other, the upper clamping airbag is arranged on the inner side of the upper fixing plate, the lower clamping airbag is arranged on the inner side of the lower fixing plate, and inflatable airbags are arranged at both ends of the upper clamping airbag. The upper and lower clamping airbags are connected by a connecting tube. By placing the affected limb of the fracture patient between the upper and lower fixing plates, the inflatable airbags are squeezed and inflated. The air bag inflates the upper and lower clamping air bags to achieve inflation and expansion of the fixing air bags, thereby fixing the affected limbs of the fractured patients to achieve a double fixation effect on the affected limb joints of the patients with distal radius fractures through the upper and lower fixing plates and the upper and lower clamping air bags, thereby ensuring the safe fixation and comfort of the patients' joints; the side splints are arranged on the inner sides of the upper clamping air bags and the lower clamping air bags through a rotating mechanism, so that the upper and lower clamping air bags squeeze the rotating mechanism while inflating to push the side splints to move to the side close to the joints, thereby avoiding the need to adjust the position of the splints individually and ensuring the safe fixation and comfort of the patients' joints.

[0023] As attached Figure 1-17As shown, a Chinese medicine small splint wrist-metacarpal joint external fixation device in an embodiment of the present invention comprises an upper fixing plate 1, a lower fixing plate 2, an upper clamping airbag 3, a lower clamping airbag 4 and a side splint 7 for fixing the joint of patients with distal radius fracture. The upper fixing plate 1 is arranged opposite to the lower fixing plate 2, the upper clamping airbag 3 is arranged on the inner side of the upper fixing plate 1, and the lower clamping airbag 4 is arranged on the inner side of the lower fixing plate 2. Inflatable airbags 5 are arranged at both ends of the upper clamping airbag 3 through a connecting pipe, and the two ends of the upper clamping airbag 3 and the lower clamping airbag 4 are connected through a connecting pipe 11. The side splint 7 is arranged on the inner side of the upper clamping airbag 3 and the lower clamping airbag 4 through a rotating mechanism 8. The side splint 7 is used for fixing the wrist-metacarpal joint of patients with distal radius fracture according to the inflation of the upper clamping airbag 3 and the lower clamping airbag 4.

[0024] In the embodiment of the present invention, a traditional Chinese medicine small splint wrist metacarpal joint external fixation device is designed, which includes an upper fixing plate, a lower fixing plate, an upper clamping airbag, a lower clamping airbag and a side splint for fixing the joint of a patient with a distal radius fracture. The upper fixing plate and the lower fixing plate are arranged opposite to each other, the upper clamping airbag is arranged on the inner side of the upper fixing plate, the lower clamping airbag is arranged on the inner side of the lower fixing plate, and inflatable airbags are arranged at both ends of the upper clamping airbag. The upper and lower clamping airbags are connected by a connecting pipe. When in use, the affected limb of the fracture patient is placed between the upper and lower fixing plates, and the fixing airbag is fixed by squeezing the airbag. Inflation realizes the inflation of the fixation airbag to fix the affected limb of the fracture patient, thereby achieving a double fixation effect on the joint of the distal radius fracture patient through the upper and lower fixation plates and the upper and lower clamping airbags, ensuring the safe fixation and comfort of the patient's joint; the side splint is arranged on the inner side of the upper clamping airbag and the lower clamping airbag through a rotating mechanism, so that when the upper and lower clamping airbags are inflated, the rotating mechanism is squeezed to push the side splint to move to the side close to the joint, avoiding the need to adjust the position of the splint alone while ensuring the safe fixation and comfort of the patient's joint.

[0025] It should be noted that the shape of the upper and lower fixing plates in the embodiment of the present application is an inward arc, and the upper and lower fixing plates are arranged relative to each other to achieve the wrapping and fixing of the fracture site of the patient with distal radius fracture. The side splint 7 is designed to be arc-shaped to fit the shape of the wrist and palm of the patient with distal radius fracture to avoid the splint piercing the patient's wrist joint. The material of the upper and lower fixing plates and the side splint can be a polymer splint, which is mainly composed of glass fiber or polyester fiber substrate, polyurethane glue and non-woven fabric. This splint has good mechanical properties and adaptability, and can meet different clinical needs. In the present application, the upper and lower fixing plates and the side splint can also use other materials that can meet the needs of fixing the fracture site of the patient with distal radius fracture, as long as the needs of fixing the fracture site of the patient with distal radius fracture can be met.

[0026] In some embodiments, as shown in the attached Figure 4-5 As shown, attached Figure 4This is a schematic diagram of the connection structure of a Chinese medicine small splint wrist-metacarpal joint external fixation device in the embodiment of the present application, without the upper fixing plate and the upper clamping airbag. Figure 5 The schematic diagram of the connection structure of a Chinese medicine small splint wrist-metacarpal joint external fixation device in the embodiment of the present application is shown in FIG. The inner sides of the upper clamping airbag 3 and the lower clamping airbag 4 are provided with elastic bands 10 , and the splint 9 is provided inside the elastic bands 10 .

[0027] By designing elastic bands on the inner sides of the upper clamping airbag and the lower clamping airbag, and placing a splint 9 of a suitable size on the inner sides of the elastic bands, when in use, the upper and lower clamping airbags are inflated so that the splints arranged on the inner sides of the upper and lower clamping airbags are close to the joints of patients with distal radius fractures at the same time, thereby fixing the upper and lower sides of the fracture site of the fracture patient, preventing the fracture site from shifting and twisting during treatment, reducing pain stimulation, improving the patient's comfort, and helping the patient to better cooperate with treatment, thereby shortening the recovery time of the fracture.

[0028] It should be noted that the size of the splint in the embodiment of the present application can be determined according to the shape of the affected limb of the patient with distal radius fracture and the actual fixation requirements to ensure the fixation effect and the patient's comfort. Specifically, the length of the fixed splint should exceed the upper and lower joints of the fracture end to ensure that the fracture site is fully fixed and prevent displacement during treatment; the width needs to adapt to the shape of the limb to ensure the fixation effect and the patient's comfort, to prevent a splint that is too narrow from not being able to provide sufficient fixation and a splint that is too wide from causing discomfort to the patient; the thickness needs to ensure sufficient hardness and strength to avoid a splint that is too thin from not being able to provide sufficient fixation and a splint that is too thick from causing discomfort to the patient. The specific size of the splint is not explained in detail here, as long as the size of the selected splint can ensure the fixation effect of the joints of patients with distal radius fractures and the patient's comfort.

[0029] In some embodiments, a plurality of limit blocks 101 are provided on the side of the upper fixing plate 1 , a plurality of limit grooves 201 are provided on the inner side of the lower fixing plate 2 , and the upper fixing plate 1 and the lower fixing plate 2 are connected by the limit blocks 101 being clamped in different limit grooves 201 .

[0030] In the embodiment of the present application, by setting limit blocks on both sides of the upper fixing plate, a plurality of groups of limit grooves 201 are provided on the inner side of the lower fixing plate, and the upper and lower fixing plates are connected by the limit blocks set on both sides of the upper fixing plate being clamped in different limit grooves set on both sides of the lower plate. On the one hand, the distance between the upper and lower fixing plates can be adjusted separately according to the different swelling conditions on both sides of the affected limb of the patient with distal radius fracture. On the other hand, the distance between the upper and lower plates is adjusted separately, so that when the squeezing airbag is used to inflate the fixing airbag to fix the patient's affected limb, different clamping degrees can be achieved when the swelling degrees on both sides of the patient's arm are different.

[0031] As attached Figure 6-7 As shown, attached Figure 6 FIG. 1 is a schematic diagram of the connection structure of an upper fixing plate, an upper clamping airbag and an elastic band of a traditional Chinese medicine small splint wrist-metacarpal joint external fixation device according to an embodiment of the present invention, and FIG. Figure 7 The present invention is a schematic diagram of the connection structure of the lower fixing plate, the lower clamping airbag and the elastic band of a Chinese medicine small splint wrist-metacarpal joint external fixation device in an embodiment of the present invention. Two limit blocks 101 are respectively arranged on both sides of the upper fixing plate 1, and the limit blocks 101 are double-ear structures. The lower fixing plate 2 is provided with limit grooves 201 corresponding to the positions of the limit blocks 101 of the upper fixing plate on both sides. Each limit block 101 is provided with a plurality of limit grooves 201 corresponding to each limit block 101. The limit grooves 201 corresponding to each limit block 101 are arranged in the vertical direction, and the slots of each limit groove 201 correspond to the shape of the double-ear structure of the limit block 101.

[0032] The upper fixing plate and the lower fixing plate are connected by clamping the limiting blocks of the upper fixing plate in different limiting grooves of the lower fixing plate. On the one hand, the distance between the upper and lower fixing plates can be adjusted separately according to the different swelling conditions on both sides of the affected limb of the patient with distal radius fracture. On the other hand, the distance between the upper and lower plates is adjusted separately, so that when the squeezing airbag is used to inflate the fixing airbag to fix the patient's affected limb, different clamping degrees can be achieved when the swelling degrees on both sides of the patient's arm are different.

[0033] As attached Figure 8-9 As shown, in some embodiments, the limit block 101 is composed of a cylindrical block and two clamping blocks symmetrically arranged on the outer circumference of the cylindrical block. The two clamping blocks on the outer circumference of the cylindrical block are columnar structures. The shape of the limit groove 201 is consistent with the shape of the clamping blocks arranged on the outer circumference of the limit block 101. By clamping the clamping blocks of the limit block in different limit grooves 201, the connection between the upper and lower fixed plates and the adjustment of different distances between the upper and lower fixed plates are achieved.

[0034] In some embodiments, as shown in the attached Figure 10-11 As shown, attached Fig.10 For attachment Figure 1 A cross-sectional view of a small splint wrist-metacarpal joint external fixation device of traditional Chinese medicine, with Fig.11 for Fig.10 Enlarged structural diagram of area A in the middle. A spring is arranged between the two clamping blocks arranged on the outer circumference of the cylindrical block on each side of the upper fixed plate 1. When in use, the limit block of the upper fixed plate is clamped in the limit groove of the lower fixed plate, and the upper fixed plate is pressed downward so that the two clamping blocks arranged on the outer circumference of the cylindrical block of the limit block of the upper fixed plate squeeze the spring arranged therebetween, so that the cylindrical block moves downward smoothly, limiting the distance between the upper and lower fixed plates, realizing the connection between the upper and lower fixed plates and the adjustment of different distances between the upper and lower fixed plates.

[0035] It should be noted that in the embodiment of the present application, the shape of the limit block and the shape and material design of the limit groove corresponding to the position of the limit block can be selected according to actual needs. As long as the connection between the upper and lower fixed plates and the adjustment of different distances between the upper and lower fixed plates can be achieved, they will not be elaborated here.

[0036] In some embodiments, a Chinese medicine small splint wrist-metacarpal joint external fixation device in the embodiment of the present application also includes a pressing mechanism 6, which is composed of a cross bar 601 and a pressing plate 602 arranged perpendicular to the cross bar, the pressing plate 602 is arranged at the upper end of the inflatable airbag 5, the pressing plate 602 is used to press the inflatable airbag 5 to inflate the upper and lower clamping airbags, so that the upper and lower clamping airbags are inflated and expanded to fix the affected limb of the fracture patient, and the end of the cross bar 601 is arranged above the limit block 101, which is used to move the upper fixing plate downward according to the pressing of the pressing plate, so as to adjust the distance between the upper and lower fixing plates. In the present application, when the inflatable airbag is squeezed by the pressing plate 602, the upper and lower clamping airbags can be inflated, and the displacement of the upper fixing plate can be moved to adjust the distance between the upper and lower fixing plates, realize the connection between the upper and lower fixing plates, adjust the different distances between the upper and lower fixing plates, and realize the technical effects of different clamping degrees when the swelling degrees on both sides of the patient's arm are different.

[0037] In the embodiment of the present application, a traditional Chinese medicine small splint wrist-metacarpal joint external fixation device is designed by the present invention, and also includes a pressing mechanism. When in use, the inflatable airbag is inflated by pressing the pressing plate downward. At the same time, due to the downward pressure on the pressing plate, the pressing plate moves downward, driving the cylindrical block to move downward in the limiting groove, so that the clamping blocks on both sides of the cylindrical block squeeze the spring to make the cylindrical block move downward smoothly. When the airbag is restored, the spring is reset, and the clamping block pops out of the limit again. On the one hand, it can limit the distance between the upper and lower fixing plates, realize the connection between the upper and lower fixing plates and the adjustment of different distances between the upper and lower fixing plates. On the other hand, by pressing the pressing plate downward, the distance between the upper and lower fixing plates is adjusted, so that when the airbags on both sides of the affected limb of the fracture patient are inflated, different clamping degrees are achieved when the swelling degrees on both sides of the patient's affected limb are different, thereby ensuring the fixation effect of the joints of patients with distal radius fractures and the comfort of the patients, and having good effects of different fixations for different situations.

[0038] In some embodiments, an opening is provided on the splint 9, and a pressure pad 15 with the same shape as the opening position is provided at the opening. The pressure pad 15 is provided on the inner sides of the upper and lower fixed plates. A push rod 14 is provided on the pressure pad 15. The end of the push rod 14 passes through the upper and lower fixed plates. The knob 13, the sleeve 16 and the spring 17 are sequentially sleeved on the end of the push rod 14. The pressure pad 15 is used to reposition the fracture site of the fracture patient according to the pushing action of the knob 13, the sleeve 16 and the spring 17 on the push rod 14.

[0039] It should be noted that the shape of the splint can be designed to be arc-shaped to fit the shape of the wrist of patients with distal radius fractures to avoid the splint piercing the patient's wrist joint. The material of the splint can be a polymer splint, which is mainly composed of glass fiber or polyester fiber substrate, polyurethane glue and non-woven fabric. This splint has good mechanical properties and adaptive adjustment capabilities, and can meet different clinical needs. The material and shape of the splint can also use other materials and shapes that can meet the needs of fixing the fracture site of patients with distal radius fractures, as long as it can meet the needs of fixing the fracture site of patients with distal radius fractures.

[0040] The material of the pressure pad can be a wooden pressure pad or a polymer pressure pad. The wooden pressure pad has toughness and elasticity, which is conducive to muscle contraction and fracture fixation; the polymer pressure pad has good mechanical properties and adaptive adjustment ability, which can meet different clinical needs. The material of the pressure pad can also use other materials that can meet the needs of fixing the fracture site of patients with distal radius fractures, as long as it can meet the needs of fixing the fracture site of patients with distal radius fractures.

[0041] Distal radius fractures are divided into two types: palmar and dorsal. By setting pressure pads on the palmar and dorsal sides, a better reduction treatment effect can be achieved. In the embodiment of the present application, an opening is designed on the splint, and a pressure pad with the same shape as the opening position is set at the opening. A push rod is set on the pressure pad, and the end of the push rod passes through the upper and lower fixed plates. The knob, sleeve and spring are sequentially sleeved on the end of the push rod. When in use, according to the needs of the palmar or dorsal side, the push rod is pushed by the knob, sleeve and spring sleeved on the end of the push rod to push the push rod, and the pressure pad built into the splint is pushed out to achieve the reduction of the fracture for the fracture patient. In the present application, by setting a knob 13, a push rod 14, a pressure pad 15, a sleeve 16 and a spring 17, the pressure pad 15 is built into the splint 9, and the pressure pad can be used as a part of the splint when not in use. When in use, the corresponding pressure pad can be controlled by the knob to pop out according to the needs of the palmar or dorsal side to reduce the fracture, achieving a better reduction treatment effect, simple operation, and significant effect.

[0042] Specifically, a spiral track is provided on the outer circumference of the sleeve 16, and the knob 13 is provided with a raised strip matching the spiral track of the sleeve 16. When in use, the knob 13 is turned, and the raised strip on the knob 13 moves on the spiral track provided on the outer circumference of the sleeve 16, so that the sleeve 16 squeezes the spring 17, thereby pushing out the push rod, so that the pressure pad connected to the bottom of the push rod pops out, and the pressure pad connected to the bottom of the push rod is retracted when it is rotated in the opposite direction. By providing a spiral track on the outer circumference of the sleeve and the knob being provided with a raised strip matching the spiral track of the sleeve, the pressure pad can be used as a part of the splint when not in use. When in use, the corresponding pressure pad can be popped out by controlling the knob according to the needs of the palm side or the dorsal side to reposition the fracture and achieve a better repositioning treatment effect.

[0043] In some embodiments, as shown in the attached Fig.17 As shown, attached Fig.17 The present invention is a schematic diagram of the structure of a rotating mechanism of a small Chinese medicine splint wrist-metacarpal joint external fixation device. The rotating mechanism 8 is a "V"-shaped structure, and the side splint 7 is arranged at the bottom of the "V"-shaped structure.

[0044] Specifically, the rotating mechanism 8 is composed of two rotating rods, the ends of the two rotating rods are connected in a "V" shape, and the ends of the two rotating rods are connected to the side splints 7, so that by adjusting the positions of the two rotating rods and the angle between the two rotating rods, the angle between the two rotating rods becomes smaller, and the position of the side splint 7 is adjusted to push the side splint close to the side of the joint to fix the affected limb of the fracture patient, avoid adjusting the position of the splint alone, and cause damage to the patient's affected limb, thereby ensuring the fixation effect of the Chinese medicine small splint wrist-metacarpal joint external fixation device of the present application.

[0045] As attached Figure 18-19 As shown, attached Fig.18 FIG. 1 is a front view of a Chinese medicine small splint wrist-metacarpal joint external fixation device used to fix the affected limb of a fracture patient in an embodiment of the present application, and FIG. Fig.19 A top view of a Chinese medicine small splint wrist-metacarpal joint external fixation device used in an embodiment of the present application to fix the affected limb of a fracture patient. A Chinese medicine small splint wrist-metacarpal joint external fixation device used in an embodiment of the present application is used to fix the affected limb of a patient with a distal radius fracture. The specific method of use is as follows: First, the affected limb 18 of the patient with distal radius fracture is placed between the upper and lower fixation plates; Next, the distance between the upper and lower fixing plates is adjusted by pressing the pressing mechanism, and the upper and lower clamping airbags are inflated by the inflatable airbags to expand the upper and lower clamping airbags. The expansion of the upper and lower clamping airbags squeezes the rotating mechanism 8, causing the side splint 7 to move toward the side close to the joint, thereby fixing the wrist metacarpal joint of patients with distal radius fractures.

[0046] Distal radius fractures are divided into two types: palmar and dorsal. In some embodiments, according to the needs of the palmar or dorsal side, the corresponding knob 13 can be adjusted to make the adjustment knob 13 move on the spiral track set on the outer periphery of the sleeve 16, so that the sleeve 16 squeezes the spring 17 downward, pushes out the push rod 14, and makes the pressure pad 15 connected to the bottom of the push rod 14 pop out, thereby achieving a better reduction treatment effect on the affected limb of the fracture patient, and the pressure pad 15 is built into the upper and lower splints, and can be used normally as a part of a traditional Chinese medicine small splint wrist metacarpal joint external fixation device in this application.

[0047] In the embodiment of the present invention, an upper fixing plate, a lower fixing plate, an upper clamping airbag, a lower clamping airbag and a side splint are provided for fixing the joint of a patient with a distal radius fracture, the upper fixing plate and the lower fixing plate are arranged opposite to each other, the upper clamping airbag is arranged on the inner side of the upper fixing plate, and the lower clamping airbag is arranged on the inner side of the lower fixing plate, and an inflatable airbag is arranged at both ends of the upper clamping airbag, and the upper and lower clamping airbags are connected by a connecting pipe. When in use, the affected limb of the fracture patient is placed between the upper and lower fixing plates, and the fixed airbag is inflated by squeezing the airbag to achieve inflation and expansion of the fixed airbag, so as to fix the affected limb of the fracture patient, thereby achieving a dual fixation effect on the joint of the patient with a distal radius fracture by the fixing plate and the airbag, and ensuring the safe fixation and comfort of the patient's joint; the side splint is arranged on the inner side of the upper clamping airbag and the lower clamping airbag through a rotating mechanism, so that when the fixed airbag is inflated and expanded, the rotating mechanism is squeezed to push the side splint to move to the side close to the joint, thereby avoiding the need to adjust the position of the splint alone and ensuring the safe fixation and comfort of the patient's joint.
