DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 4 As shown, a hand and foot deformity correction device according to an embodiment of the present invention comprises a pair of positioning rings 1, the inner wall of the positioning ring 1 is provided with an annular airbag 11, and the surface of the annular airbag 11 is connected to an air inlet head 12; a plurality of ejector rods 13 are provided in an annular shape on the inner wall of the annular airbag 11, and a fixing plate 14 is provided at one end of the ejector rod 13 close to the center of the positioning ring 1;

[0039] A pair of exhaust pipes 15 are connected to both sides of the annular airbag 11, and a blocking block 16 is inserted into the air outlet of the exhaust pipe 15. A fixing frame 17 is arranged inside the exhaust pipe 15, and a limiting column 18 is arranged on the side of the fixing frame 17. The end of the limiting column 18 close to the blocking block 16 is fixedly connected to the blocking block 16; a tension spring 19 is arranged between the blocking block 16 and the fixing frame 17;

[0040] The current device for fixing fingers after correction specifically provides a splint on the finger, fixes the bandaged finger through the splint, and wraps a cloth strip on the splint; however, in actual use, when the splint is bound and fixed by the cloth strip, it is difficult to accurately control the clamping force of the splint on the finger, which can easily lead to insufficient clamping force, poor clamping stability and excessive clamping force causing secondary damage to the finger; to solve the above problems, the embodiment of the present invention provides multiple structures such as an annular airbag 11 and an exhaust pipe 15; the specific use process is as follows; when in use, the medical staff first bandages the corrected finger, and then passes the finger to be corrected through the positioning ring 1. The present invention is suitable for the correction of deformities other than the root of the finger. After the finger passes through the positioning ring 1, the number of positioning rings 1 is adjusted according to the number of knuckles to be corrected; for example, for the correction of a finger with only one deformity, only a pair of positioning rings 1 is required, specifically one positioning ring 1 is sleeved on the normal finger knuckle, and the other positioning ring 1 is sleeved on the corrected knuckle, and then the air inlet head 12 is inflated by an external air pump, and the annular After the airbag 11 is inflated, it expands and drives the fixing plate 14 to press against the corrected knuckle through the push rod 13 to fix the corrected knuckle. At the same time, the internal air pressure of the annular airbag 11 increases synchronously when it is inflated. Under the action of the air pressure, the internal air pressure of the exhaust pipe 15 connected to the annular airbag 11 increases synchronously. When it increases to a certain level, the blocking block 16 is pushed, causing the exhaust pipe 15 to leak, thereby preventing the air pressure in the exhaust pipe 15 from further increasing. At this time, the medical staff stops inflating the annular airbag 11. The block block 16 is reset under the elastic force of the tension spring 19 to re-block the exhaust pipe 15; the exhaust pipe 15 is connected to the annular airbag 11; therefore, the restriction of the air pressure in the exhaust pipe 15 can simultaneously limit the air pressure in the annular airbag 11, so that the expansion degree of the annular airbag 11 is controlled, and then the squeezing force of the fixing plate 14 on the knuckles is controlled through the push rod 13; avoid excessive squeezing force of the fixing plate 14 on the knuckles to cause secondary injuries, and prevent the fixing plate 14 from squeezing too little on the knuckles to cause insufficient clamping stability;

[0041] It should be pointed out that the embodiment of the present invention is also applicable to fixation of toes after correction, and it is only necessary to adjust the number of positioning rings 1 during use.

[0042] like Figure 5 As shown, an arc-shaped splint 141 is provided on one side of the fixing plate 14 facing the center of the positioning ring 1; when the fixing plate 14 fixes the knuckle, the arc-shaped splint 141 is driven to press against the knuckle, and the arc-shaped surface of the arc-shaped splint 141 fully covers the knuckle, so that the knuckle is evenly stressed, which is beneficial to the protection of the knuckle.

[0043] A pair of connecting members 142 is provided on one side of the arc-shaped clamping plate 141 facing the fixed plate 14, and a fastening bolt 143 is rotatably connected to the side of the connecting member 142;

[0044] A pair of threaded holes are provided on the side of the fixing plate 14; the fastening bolts 143 engage and pass through the threaded holes; for finger joints of different sizes, medical staff can rotate the fastening bolts 143, and the fastening bolts 143 engage and connect with the threaded holes. When the fastening bolts 143 rotate, the arc splint 141 connected to the connecting piece 142 is driven to move synchronously, thereby controlling the curvature of the arc splint 141, so that the arc splint 141 is suitable for fixing finger joints of different sizes.

[0045] like Figures 2 to 6 As shown, a pair of annular nozzles 2 are symmetrically arranged on both sides of the positioning ring 1, and the air inlet of the annular nozzle 2 is aligned with the air outlet of the exhaust tube 15; there are multiple air outlets of the annular nozzle 2 and they are inclined to point to the center line of the positioning ring 1; after a period of use, the bandaged knuckles may have difficulty in heat dissipation; therefore, an annular nozzle 2 is arranged, and medical staff continuously inflate the annular airbag 11 through the air inlet head 12, so that the annular airbag 11 is continuously exhausted through the exhaust tube 15, and the gas discharged from the exhaust tube 15 is received through the air inlet of the annular nozzle 2, and then sprayed toward the knuckles, and the airflow acts on the gauze used for bandaging the knuckles. Part of the airflow will penetrate the gauze, take away the heat generated at the knuckles, and then dissipate the heat for the knuckles, which is beneficial to the recovery of the knuckles after correction; and there is no need to repeatedly disassemble and wrap the gauze to dissipate heat, thereby reducing damage to the knuckles.

[0046] like Figures 2 to 7 As shown, a plurality of arc-shaped baffles 3 are arranged on the side of the annular nozzle 2, and the arc-shaped baffles 3 are used to prevent the annular airbag 11 on both sides of the push rod 13 from expanding toward the center of the positioning ring 1; when the annular airbag 11 is inflated, the annular airbag 11 expands toward the knuckle, and drives the push rod 13 to move when expanding. In this process, the annular airbag 11 on both sides of the push rod 13 is partially restricted by the arc-shaped baffles 3, and the arc-shaped baffles 3 prevent the annular airbag 11 from expanding, thereby preventing the annular airbag 11 from being completely pressed against the corrected knuckle, affecting the normal fixation of the knuckle.

[0047] The surface of the arc-shaped baffle plate 3 is provided with an antistatic coating to prevent the annular airbag 11 from generating static electricity when it moves relative to the arc-shaped baffle plate 3, thereby preventing the user from feeling stinging when in contact with the static electricity.

[0048] A plurality of rotating rollers 31 are rotatably arranged at both ends of the arc-shaped baffle plate 3; when the annular airbag 11 moves relative to the arc-shaped baffle plate 3 and passes through the end of the arc-shaped baffle plate 3, the rotating rollers 31 will receive the moving annular airbag 11, thereby preventing the end of the arc-shaped baffle plate 3 from exerting excessive local squeezing force on the annular airbag 11, thereby causing damage to the annular airbag 11.

[0049] like Figures 8 to 11 As shown, a positioning plate 4 is provided on one side opposite to the positioning rings 1, and a connecting belt 41 is provided on one side of the positioning plate 4 away from the positioning rings 1;

[0050] A winding wheel 42 is provided at one end of the connecting belt 41 away from the positioning plate 4, and the end of the connecting belt 41 is fixedly connected to the wheel surface of the winding wheel 42; a handle is provided at the end of the winding wheel 42; when in use, the medical staff can twist the winding wheel 42 through the handle, and the winding wheel 42 will intermittently wind up the connecting belt 41, and the connecting belt 41 pulls the positioning ring 1 through the positioning plate 4, so that a pair of positioning rings 1 intermittently approach each other, thereby causing bending between different knuckles, assisting the user in exercising.

[0051] A pair of arc grooves 43 are formed at the end of the winding wheel 42. A plug-in board 44 is plugged into the arc groove 43. A connecting frame 441 is provided at one end of the plug-in board 44 outside the arc groove 43. An extrusion block 45 is provided at one end of the connecting frame 441 away from the plug-in board 44.

[0052] The extrusion block 45 is made of rubber, and an arc-shaped protrusion is provided on the side of the extrusion block 45 facing the winding wheel 42; when the user needs to continuously bend between the knuckles, after the bending angle is controlled by the winding wheel 42 to meet the requirements, the plug-in plate 44 is further inserted into the arc-shaped groove 43. In this process, the plug-in plate 44 drives the extrusion block 45 to move toward the wheel surface of the winding wheel 42 through the connecting frame 441. When contacting the wheel surface of the winding wheel 42, the arc-shaped protrusion of the extrusion block 45 is squeezed onto the wheel surface of the winding wheel 42, so that the connecting belt 41 wound onto the wheel surface of the winding wheel 42 is squeezed and fixed to the wheel surface of the winding wheel 42, thereby fixing the distance between the pair of positioning rings 1, and then fixing the angle between the knuckles fixed by the pair of positioning rings 1, which can be beneficial to further recovery of the corrected knuckles.

[0053] A binding spring 5 is arranged between a pair of positioning rings 1, and fixing pins 51 are inserted through both ends of the binding spring 5, and a round frame 52 is arranged at the bottom end of the fixing pin 51;

[0054] A plurality of intercepting posts are arranged on the surface of the circular frame 52; a fixing belt 53 is arranged between a pair of circular frames 52; when bending the knuckles for exercise, the binding spring 5 arranged between a pair of positioning rings 1 can increase the resistance for bending, thereby improving the exercise effect; and the distance between the pair of circular frames 52 can be controlled by cooperating with the circular frame 52 with the fixing belt 53. When making specific adjustments, the fixing belt 53 can be wound around the intercepting posts. The fixing belt 53 controls the distance between a pair of fixing pins 51 through the circular frame 52, and then controls the length of the initial binding spring 5 through the fixing pin 51, so that the initial length of the binding spring 5 is adapted to fingers of different sizes and lengths, thereby increasing the scope of use.

[0055] During operation, when in use, the medical staff first bandages the corrected finger, and then passes the finger to be corrected through the positioning ring 1. The present invention is suitable for correction of deformities other than the root of the finger. After the finger passes through the positioning ring 1, the number of positioning rings 1 is adjusted according to the number of knuckles to be corrected; for example, for correction of a finger with only one deformed knuckle, only a pair of positioning rings 1 is required, specifically one positioning ring 1 is sleeved on the knuckle of the normal finger, and the other positioning ring 1 is sleeved on the knuckle of the corrected finger, and then the air inlet head 12 is inflated by an external air pump, and the annular airbag After being inflated, 11 expands, and the fixing plate 14 is driven by the push rod 13 to press against the corrected knuckle to fix the corrected knuckle; at the same time, the internal air pressure of the annular airbag 11 increases synchronously when it is inflated. Under the action of the air pressure, the internal air pressure of the exhaust pipe 15 connected to the annular airbag 11 increases synchronously. When it increases to a certain level, the blocking block 16 is pushed, causing the exhaust pipe 15 to leak, thereby preventing the air pressure in the exhaust pipe 15 from further increasing; at this time, the medical staff stops inflating the annular airbag 11; the blocking block 16 is The exhaust pipe 15 is re-blocked by the elastic force of the tension spring 19; the exhaust pipe 15 is connected to the annular airbag 11; therefore, the restriction of the air pressure in the exhaust pipe 15 can simultaneously limit the air pressure in the annular airbag 11, so that the expansion degree of the annular airbag 11 is controlled, and then the squeezing force of the fixing plate 14 on the knuckles is controlled by the push rod 13; to avoid excessive squeezing force of the fixing plate 14 on the knuckles to cause secondary injury, and to prevent insufficient clamping stability due to excessive squeezing force of the fixing plate 14 on the knuckles; when the fixing plate 14 fixes the knuckles, The arc splint 141 is driven to press against the knuckles, and the arc surface of the arc splint 141 fully covers the knuckles, so that the knuckles are evenly stressed, which is beneficial to the protection of the knuckles; for knuckles of different sizes, medical staff can rotate the fastening bolts 143, and the fastening bolts 143 are engaged with the threaded holes. When the fastening bolts 143 rotate, the arc splint 141 connected to the connecting piece 142 is driven to move synchronously, thereby controlling the curvature of the arc splint 141, so that the arc splint 141 is suitable for fixing knuckles of different sizes.

[0056] After being used for a period of time, the bandaged knuckles may have difficulty in dissipating heat; therefore, an annular nozzle head 2 is provided, and medical staff continuously inflate the annular airbag 11 through the air inlet head 12, so that the annular airbag 11 is continuously exhausted through the exhaust pipe 15, and the gas exhausted by the exhaust pipe 15 is received by the air inlet port of the annular nozzle head 2, and then sprayed toward the knuckles, and the airflow acts on the gauze used for bandaging the knuckles. Part of the airflow will penetrate the gauze, take away the heat generated at the knuckles, and then dissipate the heat for the knuckles, which is beneficial to the recovery of the knuckles after correction; and there is no need to repeatedly disassemble and wrap the gauze to dissipate heat, thereby reducing damage to the knuckles; when the annular airbag 11 is inflated, the annular airbag 11 expands toward the knuckles, and when it expands, it drives the push rod 13 to move During the movement, the annular airbags 11 on both sides of the push rod 13 are partially restricted by the arc-shaped baffle plate 3, and the arc-shaped baffle plate 3 blocks the expansion of the annular airbag 11, preventing the annular airbag 11 from being completely pressed against the corrected knuckles, affecting the normal fixation of the knuckles; wherein the surface of the arc-shaped baffle plate 3 is provided with an anti-static coating; to prevent the annular airbag 11 from generating static electricity when it moves relative to the arc-shaped baffle plate 3, causing the user to feel stinging when contacting with static electricity; wherein when the annular airbag 11 moves relative to the arc-shaped baffle plate 3 and passes the end of the arc-shaped baffle plate 3, the rotating roller 31 will receive the moving annular airbag 11, to prevent the end of the arc-shaped baffle plate 3 from exerting too much local squeezing force on the annular airbag 11, causing damage to the annular airbag 11; wherein during use, medical staff can By twisting the reel 42, the reel 42 will intermittently reel up the connecting belt 41, and the connecting belt 41 pulls the positioning ring 1 through the positioning plate 4, so that the pair of positioning rings 1 intermittently approach each other, thereby causing bending between different finger joints, thereby assisting the user in exercising; when the user's finger joints need to be bent continuously, after the bending angle is controlled by the reel 42 to meet the requirements, the plug-in plate 44 is further inserted into the arc groove 43. In this process, the plug-in plate 44 drives the extrusion block 45 to move toward the wheel surface of the reel 42 through the connecting frame 441. When contacting the wheel surface of the reel 42, the arc-shaped protrusion of the extrusion block 45 is pressed against the wheel surface of the reel 42, so that the connecting belt 41 wound up to the wheel surface of the reel 42 It is squeezed and fixed to the wheel surface of the winding wheel 42, thereby fixing the distance between a pair of positioning rings 1, and then fixing the angle between the knuckles fixed by the pair of positioning rings 1, which can be beneficial to further recovery of the corrected knuckles; when bending the knuckles for exercise, the binding spring 5 arranged between the pair of positioning rings 1 can increase the resistance to bending, thereby improving the exercise effect; and the distance between the pair of circular frames 52 can be controlled by the fixing belt 53 in cooperation with the circular frame 52. When making specific adjustments, the fixing belt 53 can be wrapped around the intercepting column, and the fixing belt 53 controls the distance between a pair of fixing pins 51 through the circular frame 52, and then controls the length of the initial binding spring 5 through the fixing pin 51, so that the initial length of the binding spring 5 is adapted to fingers of different sizes and lengths, thereby improving the scope of use.
