Description

Technical Field

[0001] The invention relates to the technical field of neonatal surgery, in particular to an upper limb fixation frame for neonatal surgery. Background Art

[0002] Newborns may suffer fractures at birth due to their relatively soft bones, with clavicle fracture being the most common type. In addition to clavicle fractures, there may also be fractures in the upper limbs, mainly humeral fractures, including humeral shaft fractures, proximal humeral epiphysis separation and distal humeral epiphysis separation, which are mainly manifested in local swelling and limited movement of the limbs.

[0003] Medical staff will first use X-rays, B-ultrasound, MRI and other auxiliary examinations to confirm the diagnosis, and then use conventional external fixation methods, such as plaster fixation or splint fixation. A small number of newborns will use traction fixation. When using splint fixation, appropriate padding needs to be placed between the splint and the humeral fracture to protect the newborn's delicate skin and prevent pressure sores. Finally, use a bandage or elastic rope to fix the splint to the upper limb.

[0004] However, this method is not suitable for newborns. Firstly, newborns are more active and have poor coordination of limbs, which may cause them to swing randomly. During the process of fixing the splint, it is necessary to constantly comfort the newborn, which is time-consuming and laborious. Secondly, the process of fixing the splint device is more complicated and there are more components to be fixed. In addition, due to the different sizes of upper limbs of different newborns, the adaptation effect between the splint and the upper limb is not good, so that the splint may not be clamped firmly during use and may be out of its original position, which will have a certain impact on the recovery of the fracture position of the newborn.

[0005] Therefore, the present application provides a neonatal surgical upper limb fixation frame to meet the needs. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a neonatal surgical upper limb fixation frame to solve the existing problems that newborns are relatively active, their limbs are poorly coordinated, and they may swing randomly. During the process of fixing the splint, it is necessary to constantly comfort the newborn, which is time-consuming and laborious. Secondly, when fixing the splint device, the process is relatively cumbersome, and many components need to be fixed. In addition, due to the different sizes of upper limbs of different newborns, the adaptation effect between the splint and the upper limb is not good, so that when in use, the splint may not be clamped firmly and may be out of its original position, thereby causing a certain impact on the recovery of the position of the fracture in the newborn.

[0011] Optionally, a first snap-in groove is provided on the side of the main annular bracket, a second snap-in groove is provided on the side of the main annular bracket near a lower end of the snap-in groove, a first air-permeable groove is provided on the side of the main annular bracket, and a connecting plate is fixedly connected to the front of the main annular bracket.

[0012] Optionally, a U-shaped groove is provided on the top of the connecting plate, an arc-shaped sliding groove is provided on the front of the connecting plate, a placement groove 1 is provided at the bottom end of the connecting plate, and a clamping groove 3 is provided on the inner side of the ventilation groove 1.

[0013] Optionally, a protruding plate is fixedly connected to the side of the secondary annular bracket, an elastic plate is fixedly connected to the top of the protruding plate, a placement groove 2 is opened on the front of the protruding plate, a flexible plate 1 is fixedly connected to the inner wall of the placement groove 2, and a snap-in slot hole is opened on the front of the protruding plate.

[0014] Optionally, a flexible plate 2 is fixedly connected to the inner wall of the snap-in slot, a reinforcing plate is snap-on to the side of the bottom end of the secondary annular bracket, a guide column is installed in the middle of the secondary annular bracket, and a telescopic plate is installed in the middle of the secondary annular bracket near the lower end of the guide column.

[0015] Optionally, the slot hole is fixed in the slot opened at the top of the slide board, the cross extension frame is an existing structure, and the bottom end of the cross extension frame is slidably connected in the slot at the top of the slide board, the top of the cross extension frame is slidably connected to the bottom of the balance board, and the two sides of the U-shaped plate are fixedly connected to the middle of the cross extension frame.

[0016] Optionally, the first clamping groove and the second clamping groove both pass through the middle of the main annular bracket, the first air-permeable groove array is distributed on the outside of the main annular bracket, and the connecting plate is fixedly connected to the front side of the main annular bracket and the arc size is consistent with the arc size of the main annular bracket.

[0017] Optionally, the protruding plate is installed on the outside of the secondary annular bracket, the elastic plate is fixed to the upper and lower ends of the protruding plate, the placement groove 2 is opened on the front and back sides of the protruding plate, and the flexible plate 1 is fixedly connected to both sides of the inner wall of the placement groove 2.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] In the above scheme, after the auxiliary clamping assembly has a certain fixing effect on the upper limbs of the newborn, the sliding plate is slid to a position where the secondary annular bracket can be clamped, thereby fixing the position of the secondary annular bracket in the inner cavity of the main annular bracket. Finally, by stretching the size of the main annular bracket and the secondary annular bracket, it is ensured that the main annular bracket and the secondary annular bracket can completely cover the position of the humeral fracture of the newborn's upper limb. On the one hand, this improves the efficiency of installation and saves time and effort. On the other hand, it can improve the adaptation effect by constantly changing the position, reflecting the adaptability of the device, thereby ensuring the recovery of the fracture position of the newborn.

[0020] By setting up the placement groove one, the placement groove one can be used in conjunction with the main ring bracket. After the main ring bracket is fitted with the upper limbs of the newborn, it will not be firm enough due to the material problem of the main ring bracket. At this time, the hard board is inserted into the placement groove one, and rubber pads are provided on the inner wall of the placement groove one. In this state, if the hard board is inserted, the rubber pads on both sides can better fix the hard board in the placement groove one, thereby playing a fixing effect on the entire main ring bracket, and then having a good fixing and limiting effect on the upper limbs of the newborn.

[0021] By arranging the slots, the cross extension frame, the balance board and the U-shaped board, the sliding board makes the back sliding board and the arc-shaped slide groove slide back and forth, so that the main ring bracket and the auxiliary ring bracket are in a relatively fixed state, which can play a good role in fixing the position of the humerus of the upper limb fracture of the newborn. When it is not fixed, the balance board is manually lifted. At this time, the cross extension frame will be stretched under the action of the upward lifting force, and the slots fixed at the upper and lower ends of the cross extension frame will be tensioned at this time until the bottom end of the U-shaped board is lifted to the outer edge of the top end of the connecting plate, from The balancing board and the U-shaped board will be lowered to a position close to the top of the sliding board when the cross extension frame is in the restored state, that is, the movement trajectory of the U-shaped board is clamped in the U-shaped groove, which is the initial state of the cross extension frame, the balancing board and the U-shaped board driven by the slot hole. Finally, the auxiliary annular bracket is clamped on the inner side of the main annular bracket under the joint action of the fixed column and the U-shaped board, thereby effectively coordinating the overall state of the main annular bracket and the auxiliary annular bracket with the upper limbs of the newborn, achieving a good clamping effect, improving the overall adaptability of the device, and reducing the excessive pressure and discomfort of the device to the newborn.

[0022] By setting the protruding plate, the elastic plate, the placement groove 2, the clamping slot hole and the flexible plate 2, and determining the corresponding clamping slot 3, the fixing effect of the overall secondary ring bracket can be enhanced. This is the third-layer fixing effect, and through the fixing effects of the first and second layers, combined with the third-layer fixing effect at this time, the secondary ring bracket can be better fixed firmly inside the main ring bracket to form a stable clamping state. Finally, when everything is completely fixed, vertical movement is performed to change the length of the secondary ring bracket to adapt to the length of the upper limbs of the newborn, thereby reflecting the flexibility of the device, saving time and effort in the adaptation process, and improving the comfort of the newborn.

[0044] like Figure 1 and Fig.12As shown, an embodiment of the present invention provides a neonatal surgical upper limb fixation frame, comprising a main annular support 1, a secondary annular support 2 is installed on the side of the main annular support 1, a sliding plate 3 is installed on the front of the main annular support 1, and a telescopic column 4 is installed in the middle of the main annular support 1; an auxiliary clamping component, the auxiliary clamping component is used to strengthen the fixation on the upper limb humerus fracture of the neonate, the auxiliary clamping component is interconnected with the main annular support 1 and the secondary annular support 2, the main annular support 1 and the secondary annular support 2 are mainly made of flexible materials and have equal proportional sizes, and the middle of the main annular support 1 and the secondary annular support 2 are The main annular bracket 1 and the secondary annular bracket 2 are cut so that the main annular bracket 1 and the secondary annular bracket 2 are divided into two. The size of the main annular bracket 1 is larger than that of the secondary annular bracket 2. The position close to the front of the main annular bracket 1 is made of plastic. The sliding board 3 is slidably connected to the front of the main annular bracket 1, and the movement trajectory is synchronized with the shape of the front of the main annular bracket 1. There are two sliding boards 3, which are slidably connected to the front of the main annular bracket 1. The back of the main annular bracket 1 is smooth. The telescopic column 4 is an existing structure and is fixed through the middle of the main annular bracket 1, so that the main annular bracket 1 divided into two can be connected together.

[0045] By means of the auxiliary clamping assembly, when fixing it at the position of the humerus fracture of the upper limb of the newborn, the position of the main annular bracket 1 is first determined, and then the auxiliary annular bracket 2 is directly clamped to the position of the main annular bracket 1 from the lower end, and then clamped to the position of the main annular bracket 1 from the upper end again. At this time, the auxiliary annular bracket 2 is already in the inner cavity of the main annular bracket 1. After the positions of the main annular bracket 1 and the auxiliary annular bracket 2 are determined, so that there is a certain fixing effect on the upper limb of the newborn, the sliding plate 3 is slid to the position where the auxiliary annular bracket 2 can be clamped, thereby fixing the position of the auxiliary annular bracket 2 in the inner cavity of the main annular bracket 1. Finally, by stretching the size of the main annular bracket 1 and the auxiliary annular bracket 2, it is ensured that the main annular bracket 1 and the auxiliary annular bracket 2 can completely cover the position of the humerus fracture of the upper limb of the newborn, thereby improving the efficiency of installation and saving time and effort on the one hand, and improving the adaptation effect by constantly changing the position on the other hand, reflecting the adaptability of the device, thereby ensuring the recovery of the fracture position of the newborn.

[0046] like Figures 2 to 5As shown, the side of the main annular bracket 1 is provided with a snap-in groove 101, the side of the main annular bracket 1 near the lower end of the snap-in groove 101 is provided with a snap-in groove 102, the side of the main annular bracket 1 is provided with a venting groove 103, the front of the main annular bracket 1 is fixedly connected with a connecting plate 104, the top of the connecting plate 104 is provided with a U-shaped groove 105, the front of the connecting plate 104 is provided with an arc-shaped sliding groove 106, and the bottom of the connecting plate 104 is provided with The first slot 107 is placed, and the inner side of the ventilation slot 103 is provided with a clamping slot 3 108, the first clamping slot 101 is opened on the side of the top of the main annular bracket 1, the second clamping slot 102 is opened on the side of the top of the main annular bracket 1, and the position of the second clamping slot 102 is at the lower end of the first clamping slot 101, the slot size of the first clamping slot 101 is smaller than the slot size of the second clamping slot 102, the ventilation slot 103 is opened on the outer side of the main annular bracket 1, and the number of arrays is There are three of them, and the snap-in groove three 108 is opened on the inner side of the main annular bracket 1 and coincides with the inner side of the vent groove one 103, that is, the snap-in groove three 108 is opened on the inner side of the vent groove one 103, and the snap-in groove three 108 is distributed in a curve array on the track opened by the vent groove one 103. The connecting plate 104 is fixed on the front side of the main annular bracket 1, and its shape is consistent with the shape of the main annular bracket 1, and the connecting plate 104 is made of plastic. A groove is opened at the front position of the connecting plate 104 near its inner circle, which penetrates the connecting plate 104, and its shape is adapted to the shape left by the movement track of the secondary annular bracket 2. The U-shaped groove 105 is opened on the outer edge of the connecting plate 104, and the number of the curved array distribution is three. The arc-shaped sliding groove 106 is opened on the front side of the connecting plate 104, and its opening size is consistent with the size of the connecting plate 104. The placement groove one 107 is opened at the front position of the bottom end of the connecting plate 104 and penetrates the connecting plate 104.

[0047] Through the above structure, when the secondary annular bracket 2 enters the interior of the main annular bracket 1, it will first pass through the second clamping groove 102, and after passing through the second clamping groove 102, it will continue to move in the direction of the groove opened by the second clamping groove 102, and then in the process of the secondary annular bracket 2 moving into the interior of the main annular bracket 1, the front and back sides of the secondary annular bracket 2 will appear on the groove opened by the connecting plate 104, mainly the groove close to the inner circle of the connecting plate 104. In the process of the main annular bracket 1 and the secondary annular bracket 2 being continuously clamped to each other, the inner sides of the main annular bracket 1 and the secondary annular bracket 2 will continuously fit the humerus of the upper limb fracture of the newborn, and because the main annular bracket 1 and the secondary annular bracket 2 are The frame 2 is made of flexible material, so that it can better fit the skin of the newborn and has stronger adaptability. The placement groove 107 can be used in conjunction with the main annular bracket 1. After the main annular bracket 1 is fitted with the upper limbs of the newborn, it will not be firm enough due to the material problem of the main annular bracket 1. At this time, a hard board is inserted into the placement groove 107, and rubber pads are provided on the inner walls of the placement groove 107. In this state, if the hard board is inserted, the rubber pads on both sides can better fix the hard board in the placement groove 107, thereby playing a fixing effect on the entire main annular bracket 1, and then having a good fixing and limiting effect on the upper limbs of the newborn.

[0048] like Figures 6 to 8 As shown, the auxiliary clamping assembly includes a slot hole 301 fixedly connected to the top of the slide board 3, a cross extension frame 302 is fixedly connected to the end of the slot hole 301, a balance board 303 is fixedly connected to the top of the cross extension frame 302, a U-shaped plate 304 is installed in the middle of the balance board 303, a fixing column 305 is fixedly connected to the front of the slide board 3, a connecting column 306 is fixedly connected to the middle of the fixing column 305, a sliding plate 307 is fixedly connected to the back of the slide board 3, a weakened portion 308 is provided on the surface of the fixing column 305 close to the front of the slide board 3, the slot hole 301 is fixed in the slot at the top of the slide board 3, and the cross extension frame 302 is an existing structure, the bottom side is fixedly hung on the end of the slot hole 301, and the bottom is slidably connected to the slot at the top of the slide board 3, and the bottom of the balance board 303 is also provided with a There is a groove, which is consistent with the groove on the top of the sliding board 3, both of which are used for sliding connection to the cross extension frame 302, and the bottom of the balance board 303 is slidably connected to the top of the cross extension frame 302, the two sides of the U-shaped plate 304 are fixedly connected to the middle of the balance board 303, and the U-shaped plate 304 is "U"-shaped, and its size is consistent with the size of the U-shaped groove 105, the fixed column 305 is made of plastic material, and the curve array is distributed on the front of the sliding board 3, in an I-shape, one end is fixed to the front of the sliding board 3, and the other end is open, the connecting column 306 is made of plastic material, and runs through the fixed column 305 distributed in the curve array, the sliding plate 307 is made of plastic material, one side is fixed to the back of the sliding board 3, and the other side is slidably connected to the inner wall of the arc-shaped sliding groove 106, and the weakened portion 308 is opened at the end position of the fixed column 305 close to the sliding board 3.

[0049] Through the above structure, when the secondary annular bracket 2 is clamped into the inner cavity of the main annular bracket 1, the sliding plate 3 can be slid to make a reciprocating sliding motion between the back sliding plate 307 of the sliding plate 3 and the arc-shaped sliding groove 106, and the secondary annular bracket 2 is clamped in the inner cavity of the main annular bracket 1. After the position is fixed, the open end of the fixing column 305 can be fixedly clamped in the corresponding position of the secondary annular bracket 2. At this time, the secondary annular bracket 2 is fixed in position by the first layer, and at this time, the U-shaped plate 304 is clamped into the position of the U-shaped groove 105 to play a second layer of fixing effect, so that the two are fixed. The position of the secondary annular bracket 2 can be determined and fixed, so that the main annular bracket 1 and the secondary annular bracket 2 are in a relatively fixed state, which can play a good role in fixing the position of the humerus of the upper limb fracture of the newborn. When it is not fixed, the balance board 303 is manually lifted. At this time, the cross extension frame 302 will be stretched under the action of the upward lifting force, and the slots 301 fixed at the upper and lower ends of the cross extension frame 302 will be stretched at this time until the bottom end of the U-shaped plate 304 is lifted to the outer edge of the top of the connecting plate 104. At this time, because the bottom of the U-shaped plate 304 is against the connecting plate 104 not close to the U-shaped slot 105, the entire cross extension frame 302 is in the maximum stretched state. At this time, the cross extension frame 302 in the stretched state makes the slot 301 in the most open state. In the initial state, the cross extension frame 302 is at the lowest, and the slot 301 is in a relaxed state. At this time, the slot 301 is straightened and the cross extension frame 302 is at the highest. If there is no conflict between the bottom of the U-shaped plate 304 and the outer edge of the connecting plate 104, the cross extension frame 302 will return to its original state under the rebound effect of the slot 301, so that the balance plate 303 and the U-shaped plate 304 will be at the cross extension frame 302. In the recovery state, it is lowered to a position close to the top of the sliding board 3, that is, the movement trajectory of the U-shaped plate 304 is clamped in the U-shaped groove 105. This is the initial state of the slot hole 301 driving the cross extension frame 302, the balance board 303 and the U-shaped plate 304. Finally, through the joint action of the fixed column 305 and the U-shaped plate 304, the secondary annular bracket 2 is clamped on the inner side of the main annular bracket 1, thereby effectively coordinating the overall state of the main annular bracket 1 and the secondary annular bracket 2 with the upper limbs of the newborn, achieving a good clamping effect, improving the overall adaptability of the device, and reducing the excessive pressure and discomfort of the device on the newborn.

[0050] like Figures 9 to 12As shown, a protruding plate 201 is fixedly connected to the side of the secondary annular bracket 2, an elastic plate 202 is fixedly connected to the top of the protruding plate 201, a placement groove 203 is provided on the front of the protruding plate 201, a flexible plate 204 is fixedly connected to the inner wall of the placement groove 203, a clamping slot 205 is provided on the front of the protruding plate 201, a flexible plate 206 is fixedly connected to the inner wall of the clamping slot 205, a reinforcing plate 207 is clamped on the side of the bottom end of the secondary annular bracket 2, a guide column 208 is installed in the middle of the secondary annular bracket 2, and a telescopic plate 209 is installed in the middle of the secondary annular bracket 2 near the lower end of the guide column 208, the protruding plate 201 is fixedly connected to the middle of the outer side of the outer edge of the secondary annular bracket 2, the middle is cut into two, and the elastic plate 202 is Elastic material, and the bottom end is fixed to the upper and lower ends of the protruding plate 201, there are four of them, and the end away from the protruding plate 201 is curved, and the size of the curve is consistent with the size of the clamping slot three 108. The placement slot two 203 is opened on the front and back sides of the protruding plate 201. The flexible plate one 204 is fixed on both sides of the inner wall of the placement slot two 203. It is made of rubber material and contacts with the hard plate. The clamping slot hole 205 is opened on the front side of the secondary annular bracket 2 and is clamped with the open end of the fixing column 305. The flexible plate two 206 is fixed in the inner cavity of the clamping slot hole 205 and conflicts with the fixing column 305 to form an extrusion effect. The reinforcing plate 207 is a hard plate that can be easily disassembled and can be clamped on the inner side of the secondary annular bracket 2. The size of the clamping slot is consistent with that of the reinforcing plate 207 (such as Fig.11 ) The reinforcing plate 207 has been clamped in the clamping groove, the guide column 208 and the telescopic plate 209 are present, and both ends are fixed in the inner cavity of the secondary annular bracket 2. The secondary annular bracket 2 divided into two is driven as a whole through the telescopic structure of the guide column 208 and the telescopic plate 209.

[0051] Through the above structure, the main annular support 1 is first positioned on the humerus of the upper limb fracture of the newborn, and then the upper and lower ends of the secondary annular support 2 are both against the position of the second clamping groove 102, and then the secondary annular support 2 is horizontally moved and moved closer to the position of the main annular support 1. At this time, the upper and lower ends of the secondary annular support 2 will enter the inner cavity clamping groove 102 of the main annular support 1. As the secondary annular support 2 continues to go deeper, the front side of the secondary annular support 2 will appear on the arc-shaped slide groove 106 and slide. The fixing column 305 on the plate 3 is clamped in the flexible plate 206 and the clamping slot 205, and the weakened portion 308 on the fixing column 305 can easily change the state of the fixing column 305 to be clamped or not clamped. At the same time, after the secondary annular bracket 2 enters the inner cavity of the main annular bracket 1, the elastic plate 202 will also enter the clamping slot 1 101, and as the secondary annular bracket 2 goes deeper, the elastic plate 202 will be against the clamping slot 3 108 opened on the venting slot 1 103, and the elastic plate 2 02 The bent end can be slightly offset. When the final position is not determined, it will continuously pass through several clamping grooves 3 108 until a suitable position is found and the corresponding clamping groove 3 108 is determined, which can enhance the overall fixing effect of the secondary annular bracket 2. This is the third layer of fixing effect, and through the fixing effects of the first and second layers, combined with the third layer of fixing effect at this time, the secondary annular bracket 2 can be better fixed firmly inside the main annular bracket 1 to form a stable clamping state. In the first layer of fixing effect, the open end of the fixing column 305 is mainly clamped on the clamping slot 205 and the flexible plate 206, and the open end of the fixing column 305 will squeeze the flexible plate 206 to form a force to improve the clamping effect. Finally, when everything is completely fixed, vertical movement is performed to change the length of the secondary annular bracket 2 to adapt to the length of the upper limbs of the newborn, thereby reflecting the flexibility of the device, saving time and effort during the adaptation process, and improving the comfort of the newborn.

[0052] The workflow of the technical solution provided by the present invention is as follows:

[0053] When fixing it at the position of the humerus fracture of the upper limb of the newborn, first determine the position of the main annular bracket 1, then directly clamp the auxiliary annular bracket 2 from the lower end to the position of the main annular bracket 1, and then clamp it again from the upper end to the position of the main annular bracket 1. At this time, the auxiliary annular bracket 2 is already in the inner cavity of the main annular bracket 1. After the positions of the main annular bracket 1 and the auxiliary annular bracket 2 are determined, so that there is a certain fixing effect on the upper limb of the newborn, slide the sliding plate 3 to the position where the auxiliary annular bracket 2 can be clamped, thereby fixing the position of the auxiliary annular bracket 2 in the inner cavity of the main annular bracket 1. Finally, by stretching the size of the main annular bracket 1 and the auxiliary annular bracket 2, ensure that the main annular bracket 1 and the auxiliary annular bracket 2 can completely cover the position of the humerus fracture of the upper limb of the newborn, thereby improving the efficiency of installation and saving time and effort on the one hand, and improving the adaptation effect by constantly changing the position on the other hand, reflecting the adaptability of the device, thereby ensuring the recovery of the fracture position of the newborn.

[0054] When the secondary annular bracket 2 enters the main annular bracket 1, it will first pass through the second clamping groove 102, and after passing through the second clamping groove 102, it will continue to move in the direction of the groove opened by the second clamping groove 102, and then in the process of the secondary annular bracket 2 moving into the main annular bracket 1, the front and back sides of the secondary annular bracket 2 will appear on the groove opened by the connecting plate 104, mainly the groove close to the inner circle of the connecting plate 104. In the process of the main annular bracket 1 and the secondary annular bracket 2 constantly clamping each other, the inner sides of the main annular bracket 1 and the secondary annular bracket 2 will constantly fit the humerus of the newborn's upper limb fracture, and because the main annular bracket 1 and the secondary annular bracket 2 are flexible, the secondary annular bracket 2 will not only be loose, but also can be used for the newborn. The flexible material makes it better fit the skin of the newborn and has stronger adaptability, and the placement groove 107 can be used in conjunction with the main annular bracket 1. After the main annular bracket 1 is fitted with the upper limbs of the newborn, it will not be firm enough due to the material problem of the main annular bracket 1. At this time, the hard board is inserted into the placement groove 107, and rubber pads are provided on the inner walls of the placement groove 107. In this state, if the hard board is inserted, the rubber pads on both sides can better fix the hard board in the placement groove 107, thereby playing a fixing effect on the entire main annular bracket 1, and then having a good fixing and limiting effect on the upper limbs of the newborn.

[0055] When the secondary annular bracket 2 is clamped into the inner cavity of the main annular bracket 1, the sliding plate 3 can be slid to make a reciprocating sliding motion between the back sliding plate 307 of the sliding plate 3 and the arc-shaped sliding groove 106, and the secondary annular bracket 2 is clamped in the inner cavity of the main annular bracket 1. After the position is fixed, the open end of the fixing column 305 can be fixedly clamped in the corresponding position of the secondary annular bracket 2. At this time, the secondary annular bracket 2 is fixed in position by the first layer, and the U-shaped plate 304 is clamped into the position of the U-shaped groove 105 to play a second layer of fixing effect, so that the secondary annular bracket 2 can be fixed under these two fixations. The position of the annular bracket 2 is determined and fixed, so that the main annular bracket 1 and the auxiliary annular bracket 2 are in a relatively fixed state, which can play a good role in fixing the position of the humerus of the upper limb fracture of the newborn. When it is not fixed, the balance board 303 is manually lifted, and the cross extension frame 302 will be stretched under the force of lifting upward, and the slots 301 fixed at the upper and lower ends of the cross extension frame 302 will be stretched at this time, until the bottom end of the U-shaped plate 304 is lifted to the outer edge of the top end of the connecting plate 104. At this time, because the bottom of the U-shaped plate 304 is against the connecting plate 104 not close to the U-shaped groove 105 The outer edge of the U-shaped plate 304 is in the maximum stretched state. At this time, the cross extension frame 302 in the stretched state makes the slot 301 in the most open state. In the initial state, the cross extension frame 302 is at the lowest, and the slot 301 is in a relaxed state. At this time, the slot 301 is straightened and the cross extension frame 302 is at the highest. If there is no conflict between the bottom of the U-shaped plate 304 and the outer edge of the connecting plate 104, the cross extension frame 302 will return to its original state under the rebound effect of the slot 301, so that the balance plate 303 and the U-shaped plate 304 will return to their original state under the recovery of the cross extension frame 302. In the restored state, it is lowered to a position close to the top of the slide board 3, that is, the movement trajectory of the U-shaped plate 304 is clamped in the U-shaped groove 105. This is the initial state of the slot hole 301 driving the cross extension frame 302, the balance board 303 and the U-shaped plate 304. Finally, through the joint action of the fixing column 305 and the U-shaped plate 304, the auxiliary annular bracket 2 is clamped on the inner side of the main annular bracket 1, thereby effectively coordinating the overall state of the main annular bracket 1 and the auxiliary annular bracket 2 with the upper limbs of the newborn, achieving a good clamping effect, improving the overall adaptability of the device, and reducing the excessive pressure and discomfort of the device on the newborn.

[0056] Finally, the main annular support 1 is first positioned on the humerus of the upper limb fracture of the newborn, and then the upper and lower ends of the secondary annular support 2 are both placed against the position of the second clamping groove 102, and then the secondary annular support 2 is horizontally moved and moved closer to the position of the main annular support 1. At this time, the upper and lower ends of the secondary annular support 2 will enter the inner cavity clamping groove 102 of the main annular support 1. As the secondary annular support 2 continues to go deeper, the front side of the secondary annular support 2 will appear on the arc-shaped slide groove 106 and pass through the slide plate 3. The fixing column 305 on the surface is clamped in the flexible plate 206 and the clamping slot 205, and the weakened portion 308 on the fixing column 305 can easily change the state of the fixing column 305 to be clamped or not clamped. At the same time, after the secondary annular bracket 2 enters the inner cavity of the main annular bracket 1, the elastic plate 202 will also enter the clamping slot 1 101. As the secondary annular bracket 2 goes deeper, the elastic plate 202 will be against the clamping slot 3 108 opened on the venting slot 1 103, and the elastic plate 202 The bent end can be slightly offset. When the final position is not determined, it will continuously pass through several clamping grooves 3 108 until a suitable position is found and the corresponding clamping groove 3 108 is determined, which can enhance the fixing effect of the overall secondary annular bracket 2. This is the third layer of fixing effect, and through the fixing effects of the first and second layers, combined with the third layer of fixing effect at this time, the secondary annular bracket 2 can be better fixed firmly inside the main annular bracket 1 to form a stable clamping state. In the first layer of fixing effect, the open end of the fixing column 305 is mainly clamped on the clamping slot 205 and the flexible plate 206, and the open end of the fixing column 305 will squeeze the flexible plate 206 to form a force to improve the clamping effect. Finally, when everything is completely fixed, vertical movement is performed to change the length of the secondary annular bracket 2 to adapt to the length of the upper limbs of the newborn, thereby reflecting the flexibility of the device, saving time and effort during the adaptation process, and improving the comfort of the newborn.
