Description

Technical Field

[0001] The present invention relates to the technical field of neonatal surgery, and particularly relates to an upper limb fixing frame for neonatal surgery. Background Art

[0002] Newborns have relatively soft bones and may experience fractures at birth. Clavicle fractures are the most common type. In addition to clavicle fractures, there may also be fractures in the upper arm, mainly humeral fractures, including humeral shaft fractures, proximal humeral epiphyseal separations, and distal humeral epiphyseal separations, etc., which are mainly manifested as local swelling and limited movement of the limb.

[0003] Medical staff will first use auxiliary examinations such as X-ray films, B-ultrasound, and MRI for diagnosis, and then use conventional external fixation methods, such as plaster fixation or splint fixation. In a small number of cases, traction fixation is used for newborns. When using splint fixation, appropriate pads need to be placed between the splint and the humeral fracture site to protect the delicate skin of the newborn and prevent pressure sores. Finally, the splint is fixed to the upper limb using a bandage or an elastic rope.

[0004] However, for newly born newborns, on the one hand, newborns are relatively active and have poor limb coordination, and will swing around randomly. During the process of fixing the splint, it is necessary to continuously soothe the state of the newborn, which is time-consuming and laborious. Secondly, when the splint device is fixed, the process is relatively cumbersome, and there are many components to be fixed. Moreover, due to the different upper limb sizes of different newborns, the fitting effect between the splint and the upper limb is not good, so that the splint may not be firmly clamped and may deviate from its original position during use, which will have a certain impact on the recovery of the fracture site of the newborn.

[0005] Therefore, the present application provides an upper limb fixing frame for neonatal surgery to meet the needs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an upper limb fixing frame for neonatal surgery to solve the problems that, on the one hand, newborns are relatively active and have poor limb coordination, and will swing around randomly. During the process of fixing the splint, it is necessary to continuously soothe the state of the newborn, which is time-consuming and laborious. Secondly, when the splint device is fixed, the process is relatively cumbersome, and there are many components to be fixed. Moreover, due to the different upper limb sizes of different newborns, the fitting effect between the splint and the upper limb is not good, so that the splint may not be firmly clamped and may deviate from its original position during use, which will have a certain impact on the recovery of the fracture site of the newborn.

[0010] Optionally, a fixing column is fixedly connected to the front of the sliding plate, a connecting column is fixedly connected to the middle of the fixing column, a sliding plate is fixedly connected to the back of the sliding plate, and a weakening part is provided on the surface of the fixing column close to the front of the sliding plate.

[0011] Optionally, a first clamping groove is provided on the side of the main circular bracket, a second clamping groove is provided on the side of the main circular bracket near the lower end of the first clamping groove, a first ventilation groove is provided on the side of the main circular bracket, and a connecting plate is fixedly connected to the front of the main circular 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 first placement groove is provided at the bottom end of the connecting plate, and a third clamping groove is provided inside the first ventilation groove.

[0013] Optionally, a protruding plate is fixedly connected to the side of the secondary circular bracket, an elastic plate is fixedly connected to the top of the protruding plate, a second placement groove is provided on the front of the protruding plate, a first flexible plate is fixedly connected to the inner wall of the second placement groove, and a clamping groove hole is provided on the front of the protruding plate.

[0014] Optionally, a second flexible plate is fixedly connected to the inner wall of the clamping groove hole, a reinforcing plate is clamped to the side at the bottom end of the secondary circular bracket, a guiding column is installed in the middle of the secondary circular bracket, and a telescopic plate is installed in the middle of the secondary circular bracket near the lower end of the guiding column.

[0015] Optionally, the slot is fixed in the opening groove at the top of the sliding plate, the cross extension frame is an existing structure, and the bottom end of the cross extension frame is slidably connected in the groove at the top of the sliding plate, the top of the cross extension frame is slidably connected to the bottom of the balance plate, and both sides of the U-shaped plate are fixedly connected to the middle of the cross extension frame.

[0016] Optionally, both the first clamping groove and the second clamping groove penetrate through the middle of the main annular bracket. The first ventilation groove array is distributed on the outer side of the main annular bracket. The connecting plate is fixedly connected to the front of the main annular bracket and has an arc size consistent with that of the main annular bracket.

[0017] Optionally, the protruding plate is installed on the outer side of the auxiliary annular bracket. The elastic plates are fixed to the upper and lower ends of the protruding plate. The second placement groove is formed on the front and back sides of the protruding plate. The first flexible plate is fixedly connected to both sides of the inner wall of the second placement groove.

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

[0019] In the above solution, after the neonatal upper limb is fixed to a certain extent by the above auxiliary clamping assembly, the sliding plate is slid to a position where it can be clamped to the auxiliary annular bracket, so as to fix the position of the auxiliary annular bracket in the inner cavity of the main annular bracket. Finally, by stretching the sizes of the main annular bracket and the auxiliary annular bracket, it is ensured that the main annular bracket and the auxiliary annular bracket can completely cover the position of the neonatal upper limb humeral fracture. On the one hand, the installation efficiency is improved, saving time and effort. On the other hand, the adaptability effect can be improved by continuously changing the position, reflecting the adaptability of the device, so as to ensure the recovery of the neonatal fracture position.

[0020] By providing the first placement groove, the first placement groove can be used in cooperation with the main annular bracket. After the main annular bracket is attached to the neonatal upper limb, it may be not firm enough due to the material of the main annular bracket. At this time, the hard plate is inserted into the first placement groove, and rubber pads are provided on the inner walls of the first placement groove. In this state, if the hard plate is inserted, the hard plate can be better fixed in the first placement groove by relying on the rubber pads on both sides, thereby achieving a fixing effect on the entire main annular bracket, and further achieving a good fixing and limiting effect on the neonatal upper limb.

[0021] By setting slots, cross extension frames, balance plates and U-shaped plates, sliding the sliding plate causes the back sliding plate of the sliding plate to make a reciprocating sliding motion between the arc-shaped sliding grooves, so that the main annular bracket and the auxiliary annular bracket are in a relatively fixed state, which can play a good fixing role in the position of the humerus of the neonatal upper limb fracture. When not fixed, manually lift the balance plate. At this time, the cross extension frame will be stretched under the upward lifting force, and the slots fixed at the upper and lower ends of the cross extension frame will be tensioned until the bottom end of the U-shaped plate is lifted to the outer edge of the top end of the connecting plate. Thus, the balance plate and the U-shaped plate will drop to a position close to the top of the sliding plate in the restored state of the cross extension frame, that is, the movement track of the U-shaped plate is clamped in the U-shaped groove. This is the initial state of the slots driving the cross extension frame, the balance plate and the U-shaped plate. Finally, through the combined action of the fixing column and the U-shaped plate, the auxiliary annular bracket is clamped inside the main annular bracket, so as to effectively match the overall state of the main annular bracket and the auxiliary annular bracket with the neonatal upper limb, play a good clamping effect, improve the overall adaptability of the device, and reduce the excessive compression and discomfort of the device on the neonate.

[0022] By setting the protruding plate, elastic plate, placing groove two, clamping slot holes and flexible plate two, and determining the corresponding clamping slot three, the overall fixing effect of the auxiliary annular bracket can be enhanced. This is the third-layer fixing effect. And through the fixing effects of the first layer and the second layer, combined with the current third-layer fixing effect, the auxiliary annular bracket can be better fixed firmly inside the main annular bracket to form a stable clamping state. Finally, when it is completely fixed, make a vertical movement to change the length of the auxiliary annular bracket to adapt to the length of the neonatal upper limb, thus reflecting the flexibility of the device, and also making it time-saving and labor-saving during the adaptation process, and improving the comfort of the neonate.

[0044] Such as Figure 1 and Figure 12As shown in the figure, an upper limb fixing bracket for neonatal surgery provided by an embodiment of the present invention includes a main annular bracket 1. A secondary annular bracket 2 is installed on the side of the main annular bracket 1. A sliding plate 3 is installed on the front of the main annular bracket 1. A telescopic column 4 is installed in the middle of the main annular bracket 1; an auxiliary clamping assembly is used to enhance the fixation at the humeral fracture of the upper limb of a neonate. The auxiliary clamping assembly is connected to the main annular bracket 1 and the secondary annular bracket 2. The main annular bracket 1 and the secondary annular bracket 2 are mainly made of flexible materials and have the same proportional size. The middle parts of 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 near the front of the main annular bracket 1 is made of plastic. The sliding plate 3 is slidably connected to the front of the main annular bracket 1, and its movement trajectory is synchronized with the shape of the front of the main annular bracket 1. The number of sliding plates 3 is two, and they are slidably connected to the front of the main annular bracket 1. The back of the main annular bracket 1 is in a smooth state. The telescopic column 4 is an existing structure and is fixedly installed through the middle of the main annular bracket 1, so that the divided main annular bracket 1 can be connected together.

[0045] Through the above-mentioned auxiliary clamping assembly, when fixing it at the position of the humeral fracture of the upper limb of a neonate, first determine the position of the main annular bracket 1, and then directly snap the secondary annular bracket 2 onto the main annular bracket 1 from the lower end, and then snap it onto the main annular bracket 1 again from the upper end. At this time, the secondary 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 secondary annular bracket 2 are determined and there is a certain fixing effect on the upper limb of the neonate, slide the sliding plate 3 to a position where it can snap the secondary annular bracket 2, so as to fix the position of the secondary annular bracket 2 in the inner cavity of the main annular bracket 1. Finally, by stretching the sizes of the main annular bracket 1 and the secondary annular bracket 2, ensure that the main annular bracket 1 and the secondary annular bracket 2 can completely cover the position of the humeral fracture of the upper limb of the neonate. On the one hand, the installation efficiency is improved, saving time and effort. On the other hand, the adaptability effect can be improved by continuously changing the position, reflecting the adaptability of the device, so as to ensure the recovery of the fracture position of the neonate.

[0046] Such as Figures 2 to 5As shown in the figure, a first clamping groove 101 is formed on the side surface of the main annular bracket 1, a second clamping groove 102 is formed on the side surface of the main annular bracket 1 near the lower end of the first clamping groove 101, a first ventilation groove 103 is formed on the side surface of the main annular bracket 1, a connecting plate 104 is fixedly connected to the front surface of the main annular bracket 1, a U-shaped groove 105 is formed at the top of the connecting plate 104, an arc-shaped sliding groove 106 is formed on the front surface of the connecting plate 104, a first placing groove 107 is formed at the bottom end of the connecting plate 104, a third clamping groove 108 is formed inside the first ventilation groove 103, the first clamping groove 101 is formed on the side surface at the top of the main annular bracket 1, the second clamping groove 102 is formed on the side surface at the top of the main annular bracket 1, and the position of the second clamping groove 102 is at the lower end of the first clamping groove 101. The opening size of the first clamping groove 101 is smaller than that of the second clamping groove 102. The first ventilation groove 103 is formed on the outer side of the main annular bracket 1, and the array number is three. The third clamping groove 108 is formed at the inner position of the main annular bracket 1 and coincides with the inner side of the first ventilation groove 103, that is, the third clamping groove 108 is formed inside the first ventilation groove 103. The third clamping groove 108 is distributed in a curve array on the track where the first ventilation groove 103 is formed. The connecting plate 104 is fixed to the front surface of the main annular bracket 1, and its shape is the same as that of the main annular bracket 1. The connecting plate 104 is made of plastic. A groove is formed at the front position near the inner circle of the connecting plate 104, passing through the connecting plate 104, and its shape is adapted to the shape left by the movement track of the auxiliary annular bracket 2. The U-shaped groove 105 is formed at the outer edge of the connecting plate 104, and the curve array distribution number is three. The arc-shaped sliding groove 106 is formed on the front surface of the connecting plate 104, and its opening size is the same as that of the connecting plate 104. The first placing groove 107 is formed at the front position at the bottom end of the connecting plate 104 and passes through the connecting plate 104.

[0047] With the above structure, when the secondary annular bracket 2 enters the interior of the primary annular bracket 1, it will first pass through the second clamping groove 102. After passing through the second clamping groove 102, it will continue to move forward in the direction of the groove opened by the second clamping groove 102. Then, during the process of the secondary annular bracket 2 moving into the interior of the primary annular bracket 1, the front and back surfaces of the secondary annular bracket 2 will appear on the grooves opened on the connecting plate 104, mainly the grooves on the connecting plate 104 close to the inner circle. During the continuous mutual clamping process of the primary annular bracket 1 and the secondary annular bracket 2, the inner sides of the primary annular bracket 1 and the secondary annular bracket 2 will continuously fit on the humerus of the neonatal upper limb fracture. Moreover, since the primary annular bracket 1 and the secondary annular bracket 2 are made of flexible materials, the effect of fitting on the skin of the neonate is better and the adaptability is stronger. The first placement groove 107 can be used in cooperation with the primary annular bracket 1. After the primary annular bracket 1 fits with the upper limb of the neonate, it may be not firm enough due to the material problem of the primary annular bracket 1. At this time, the hard board is inserted into the interior of the first placement groove 107, and rubber pads are arranged on the inner walls of the first placement groove 107. In this state, if the hard board is inserted, the hard board can be better fixed in the first placement groove 107 by relying on the rubber pads on both sides, thereby achieving the fixing effect on the entire primary annular bracket 1, and further achieving a good fixing and limiting effect on the upper limb of the neonate.

[0048] As Figures 6 to 8 shown, the auxiliary clamping assembly includes a slot hole 301 fixedly connected to the top of the sliding plate 3. A cross-shaped extension frame 302 is fixedly connected to the end of the slot hole 301. A balance plate 303 is fixedly connected to the top of the cross-shaped extension frame 302. A U-shaped plate 304 is installed in the middle of the balance plate 303. A fixed column 305 is fixedly connected to the front surface of the sliding plate 3. A connecting column 306 is fixedly connected to the middle of the fixed column 305. A sliding plate 307 is fixedly connected to the back surface of the sliding plate 3. A weakening part 308 is formed on the surface of the fixed column 305 close to the front surface of the sliding plate 3. The slot hole 301 is fixed in the slot on the top of the sliding plate 3, and the cross-shaped extension frame 302 is an existing structure, with its bottom side fixedly hung at the end of the slot hole 301 and its bottom slidingly connected in the slot on the top of the sliding plate 3. A slot is also opened in the bottom of the balance plate 303, which is the same as the slot on the top of the sliding plate 3 and is used for slidingly connecting the cross-shaped extension frame 302. Moreover, the bottom of the balance plate 303 is slidingly connected to the top of the cross-shaped extension frame 302. The two sides of the U-shaped plate 304 are fixedly connected to the middle of the balance plate 303, and the U-shaped plate 304 is "U"-shaped, and its size is the same as that of the U-shaped groove 105. The fixed column 305 is made of plastic material, distributed in a curved array on the front surface of the sliding plate 3, in an I-shaped shape, with one end fixed to the front surface of the sliding plate 3 and the other end being open. The connecting column 306 is made of plastic material and passes through the fixed columns 305 distributed in a curved array. The sliding plate 307 is made of plastic material, with one side fixed to the back surface of the sliding plate 3 and the other side slidingly connected to the inner wall of the arc-shaped sliding groove 106. The weakening part 308 is formed at the position of the end of the fixed column 305 close to the sliding plate 3.

[0049] With the above structure, when the auxiliary annular bracket 2 is snapped into the inner cavity of the main annular bracket 1, the back sliding plate 307 of the sliding plate 3 can slide reciprocally with the arc-shaped sliding groove 106 by sliding the sliding plate 3. At this time, the auxiliary annular bracket 2 is snapped into 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 snapped into the corresponding position of the auxiliary annular bracket 2. At this time, the auxiliary annular bracket 2 is fixed in position by the first layer. Then, when the U-shaped plate 304 is snapped into the U-shaped groove 105, it plays a second fixing effect. Thus, under the fixation of these two, the position of the auxiliary annular bracket 2 can be determined and fixed, and then the main annular bracket 1 and the auxiliary annular bracket 2 are in a relatively fixed state, which can play a good fixing role for the position of the neonatal upper limb fracture of the humerus. When not fixed, manually lift the balance plate 303. At this time, the cross extension frame 302 will be stretched under the upward lifting force. At this time, the slot holes 301 fixed at the upper and lower ends of the cross extension frame 302 will be tensioned until the bottom end of the U-shaped plate 304 rises to the outer edge of the top end of the connecting plate 104. At this time, since the bottom of the U-shaped plate 304 abuts against the outer edge of the connecting plate 104 that is not close to the U-shaped groove 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 will make the slot holes 301 in the state of the largest opening degree. In the initial state, the cross extension frame 302 is at the lowest position, and the slot holes 301 are in a relaxed state. At this time, the slot holes 301 will be straightened, and the cross extension frame 302 is at the highest position. Without the bottom of the U-shaped plate 304 abutting against the outer edge of the connecting plate 104, the cross extension frame 302 will return to its original state under the elastic return of the slot holes 301. Thus, the balance plate 303 and the U-shaped plate 304 will drop to a position close to the top of the sliding plate 3 under the restoration state of the cross extension frame 302, that is, the movement track of the U-shaped plate 304 is snapped into the U-shaped groove 105. This is the initial state of the slot holes 301 driving the cross extension frame 302, the balance plate 303 and the U-shaped plate 304. Finally, under the combined action of the fixing column 305 and the U-shaped plate 304, the auxiliary annular bracket 2 is snapped inside the main annular bracket 1, effectively matching the overall state of the main annular bracket 1 and the auxiliary annular bracket 2 with the neonatal upper limb, playing a good clamping effect, improving the overall adaptability of the device, and reducing the excessive compression and discomfort of the device on the neonate.

[0050] Such as 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 Figure 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] With the above structure, first determine the position of the main annular bracket 1 on the humerus of the neonatal upper limb fracture. Then, press both the upper and lower ends of the auxiliary annular bracket 2 against the position of the second clamping groove 102. Next, horizontally move the auxiliary annular bracket 2 and move it closer to the position of the main annular bracket 1. At this time, the upper and lower ends of the auxiliary annular bracket 2 will enter the inner cavity of the main annular bracket 1, i.e., the second clamping groove 102. During the continuous penetration of the auxiliary annular bracket 2, the front surface of the auxiliary annular bracket 2 will appear on the arc-shaped sliding groove 106 and be clamped in the flexible plate II 206 and the clamping groove hole 205 through the fixing column 305 on the sliding plate 3. The weakening part 308 on the fixing column 305 can easily change the state of the fixing column 305, whether it is clamped or not. At the same time, after the auxiliary annular bracket 2 enters the inner cavity of the main annular bracket 1, the elastic plate 202 will also enter the first clamping groove 101. As the auxiliary annular bracket 2 penetrates deeper, the elastic plate 202 will abut against the third clamping groove 108 opened on the first ventilation groove 103, and the bent end of the elastic plate 202 can be slightly offset. Before determining the final position, it will continuously pass through several third clamping grooves 108 until a suitable position is found and the corresponding third clamping groove 108 is determined, which can enhance the overall fixing effect of the auxiliary annular bracket 2. This is the third layer of fixing effect. And through the fixing effects of the first layer and the second layer, combined with the current third layer of fixing effect, the auxiliary 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, mainly the open end of the fixing column 305 is clamped on the clamping groove hole 205 and the flexible plate II 206, and the open end of the fixing column 305 will mutually extrude with the flexible plate II 206 to form a force, improving the clamping effect. Finally, when it is completely fixed, move vertically to change the length of the auxiliary annular bracket 2 to adapt to the length of the neonatal upper limb, thus reflecting the flexibility of the device, saving time and effort during the adaptation process, and improving the comfort of the neonate.

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

[0053] When fixing it at the position of the neonatal upper limb humeral fracture, first determine the position of the main circular bracket 1, and then directly snap the auxiliary circular bracket 2 onto the main circular bracket 1 from the lower end first, and then snap it onto the main circular bracket 1 from the upper end again. At this time, the auxiliary circular bracket 2 is already inside the inner cavity of the main circular bracket 1. After the positions of the main circular bracket 1 and the auxiliary circular bracket 2 are determined and have a certain fixing effect on the neonatal upper limb, slide the sliding plate 3 to a position where it can snap onto the auxiliary circular bracket 2, thereby fixing the position of the auxiliary circular bracket 2 inside the inner cavity of the main circular bracket 1. Finally, by stretching the sizes of the main circular bracket 1 and the auxiliary circular bracket 2, ensure that the main circular bracket 1 and the auxiliary circular bracket 2 can completely cover the position of the neonatal upper limb humeral fracture. On the one hand, this improves the installation efficiency, saving time and effort. On the other hand, the adaptability can be improved by continuously changing the position, reflecting the adaptability of the device, and thus ensuring the recovery of the neonatal fracture position.

[0054] When the auxiliary circular bracket 2 enters the inside of the main circular bracket 1, it will first pass through the second clamping groove 102. After passing through the second clamping groove 102, it will continue to move forward in the direction of the groove opened by the second clamping groove 102. Then, during the movement of the auxiliary circular bracket 2 into the main circular bracket 1, the front and back surfaces of the auxiliary circular bracket 2 will appear on the grooves opened on the connecting plate 104, mainly the grooves on the connecting plate 104 close to the inner circle. During the continuous mutual clamping of the main circular bracket 1 and the auxiliary circular bracket 2, the inner sides of the main circular bracket 1 and the auxiliary circular bracket 2 will continuously fit onto the humerus of the neonatal upper limb fracture. And because the main circular bracket 1 and the auxiliary circular bracket 2 are made of flexible materials, the effect of fitting onto the neonatal skin is better and the adaptability is stronger. The first placement groove 107 can be used in conjunction with the main circular bracket 1. After the main circular bracket 1 fits onto the neonatal upper limb, due to the material problem of the main circular bracket 1, it may not be firm enough. At this time, insert the hard board into the inside of the first placement groove 107, and rubber pads are provided on the inner walls of the first placement groove 107. In this state, if the hard board is inserted, relying on the rubber pads on both sides, the hard board can be better fixed in the first placement groove 107, thereby achieving a fixing effect on the entire main circular bracket 1, and further achieving a good fixing and limiting effect on the neonatal upper limb.

[0055] When the auxiliary annular bracket 2 is snapped into the inner cavity of the main annular bracket 1, the back sliding plate 307 of the sliding plate 3 can be slid to make a reciprocating sliding motion between the arc-shaped chute 106. At this time, the auxiliary annular bracket 2 is snapped into 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 snapped into the corresponding position of the auxiliary annular bracket 2. At this time, the auxiliary annular bracket 2 is fixed in position by the first layer. Then, when the U-shaped plate 304 is snapped into the U-shaped groove 105, it plays a second-layer fixing effect. Thus, under the fixing of these two, the position of the auxiliary annular bracket 2 can be 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 fixing role for the position of the neonatal upper limb fracture of the humerus. When not fixed, the balance plate 303 is manually lifted. At this time, the cross extension frame 302 will be stretched under the upward lifting force. The slot holes 301 fixed at the upper and lower ends of the cross extension frame 302 will be tensioned 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, since the bottom of the U-shaped plate 304 abuts against the outer edge of the connecting plate 104 that is not close to the U-shaped groove 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 will make the slot holes 301 in the state of the largest opening degree. In the initial state, the cross extension frame 302 is at the lowest, the slot holes 301 are in a relaxed state, and at this time, the slot holes 301 will be straightened, and the cross extension frame 302 is at the highest. Without the bottom of the U-shaped plate 304 abutting against the outer edge of the connecting plate 104, the cross extension frame 302 will return to its original state under the elastic return of the slot holes 301. Thus, the balance plate 303 and the U-shaped plate 304 will be lowered to a position close to the top of the sliding plate 3 in the restored state of the cross extension frame 302, that is, the movement track of the U-shaped plate 304 is snapped into the U-shaped groove 105. This is the initial state of the slot holes 301 driving the cross extension frame 302, the balance plate 303 and the U-shaped plate 304. Finally, under the combined action of the fixing column 305 and the U-shaped plate 304, the auxiliary annular bracket 2 is snapped inside the main annular bracket 1, so as to effectively cooperate the overall state of the main annular bracket 1 and the auxiliary annular bracket 2 with the neonatal upper limb, play a good clamping effect, improve the overall adaptability of the device, and reduce the excessive pressing feeling and discomfort of the device on the neonate.

[0056] Finally, first determine the position of the main annular bracket 1 on the humerus of the neonatal upper limb fracture. Then, place both the upper and lower ends of the auxiliary annular bracket 2 against the position of the second clamping groove 102. Next, horizontally move the auxiliary annular bracket 2 closer to the position of the main annular bracket 1. At this time, the upper and lower ends of the auxiliary annular bracket 2 will enter the inner cavity of the main annular bracket 1, i.e., the second clamping groove 102. During the continuous insertion of the auxiliary annular bracket 2, the front of the auxiliary annular bracket 2 will appear on the arc-shaped sliding groove 106 and be clamped in the flexible plate II 206 and the clamping groove hole 205 through the fixing column 305 on the sliding plate 3. The weakening part 308 on the fixing column 305 can conveniently change the state of the fixing column 305, whether it is clamped or not. At the same time, after the auxiliary annular bracket 2 enters the inner cavity of the main annular bracket 1, the elastic plate 202 will also enter the first clamping groove 101. As the auxiliary annular bracket 2 is inserted deeper, the elastic plate 202 will abut against the third clamping groove 108 opened on the first ventilation groove 103, and the bent end of the elastic plate 202 can be slightly offset. Before the final position is determined, it will continuously pass through several third clamping grooves 108 until the appropriate position is found and the corresponding third clamping groove 108 is determined, which can enhance the overall fixing effect of the auxiliary annular bracket 2. This is the third layer of the fixing effect. And through the fixing effects of the first layer and the second layer, combined with the current third layer of the fixing effect, the auxiliary 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 the fixing effect, mainly the open end of the fixing column 305 is clamped on the clamping groove hole 205 and the flexible plate II 206, and the open end of the fixing column 305 will mutually squeeze with the flexible plate II 206 to form a force, improving the clamping effect. Finally, when it is completely fixed, make a vertical movement to change the length of the auxiliary annular bracket 2 to adapt to the length of the neonatal upper limb, thereby reflecting the flexibility of the device, saving time and effort during the adaptation process, and improving the comfort of the neonate.
