Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical puncture, in particular to a child body position fixing structure and a puncture bed. BACKGROUND

[0002] Puncture is a common clinical diagnosis and treatment technology, mainly including lumbar puncture, bone marrow puncture, abdominal puncture and intravenous puncture. The following will be described in combination with the clinical operation points: 1. Lumbar puncture is to obtain cerebrospinal fluid specimen through L3-L4 or L4-L5 intervertebral space puncture, which is an important operation for cerebrospinal fluid routine, biochemical, pathogenic detection and intracranial pressure determination. This technology is mainly applied to the diagnosis and treatment of central nervous system infection, cerebrovascular disease, demyelination disease, etc., and can also be used for intrathecal administration and anesthesia. When operating, the patient takes left lateral position, the back is perpendicular to the bed surface, the head is bent forward, the knees are bent and close to the chest and abdomen, so that the spine is fully flexed to enlarge the intervertebral space. After successful puncture, connect the pressure measuring tube to measure the initial pressure, take cerebrospinal fluid for detection or intrathecal injection treatment. 2. Bone marrow puncture is a routine method for obtaining bone marrow fluid for diagnosis of blood system diseases, infectious diseases and genetic examination. The puncture fluid can be used for cell morphology, cytogenetics, molecular biology and pathogenic microorganism detection. The posterior superior iliac spine is the preferred puncture site for adults and children, followed by the anterior superior iliac spine and the sternum, and children can also choose the sternum puncture and tibial puncture. When puncturing, the anterior superior iliac spine and the sternum puncture take supine position, the posterior superior iliac spine puncture takes prone position or lateral position, the sternum puncture needs supine position, and the tibial puncture takes supine position. The operation needs to be carried out under strict sterile conditions, using local infiltration anesthesia, and obtaining appropriate amount of bone marrow fluid by negative pressure suction. 3. Abdominal puncture is a common technique for diagnosing ascitic fluid analysis or therapeutic abdominal decompression by puncturing the abdominal wall into the peritoneal cavity. The diagnostic puncture usually selects the left lower abdomen at 1 / 3 of the line connecting the navel and the anterior superior iliac spine; the therapeutic puncture can select the intersection of the navel horizontal line and the anterior axillary line when supine. The bladder needs to be emptied before operation, and strict aseptic operation is required. After local anesthesia, the needle is slowly inserted in Z-shaped path to avoid ascitic fluid leakage, and vital signs are closely monitored after operation. 4. Intravenous puncture is the most commonly used treatment and blood sampling method in clinic. Pediatric intravenous puncture needs to reasonably select the puncture site according to age: children under 2 years old usually choose scalp vein, children over 2 years old can choose dorsal vein, dorsal vein or great saphenous vein. When operating, the patient usually takes supine position, and the puncture site and the child's limbs are properly fixed. Choose the appropriate size of the puncture needle, and properly fix it after successful puncture to prevent it from falling out.

[0003] In clinical puncture operation, the correct acquisition and maintenance of body position is the key link to ensure the smooth implementation of the operation. However, children, especially infants, are difficult to actively cooperate and maintain a specific body position for a long time, and often need the assistance of multiple medical staff or parents to brake, which not only increases the difficulty of the operation, but also affects the success rate and safety of puncture. At present, the body position management of some puncture operations is relatively simple, such as abdominal puncture and bone marrow puncture, which usually adopt supine position or prone position, and the fixation is relatively easy. However, lumbar puncture requires the child to lie on the operating table with the back perpendicular to the table surface, the head bent close to the chest, and the hands holding the knees to make the body flexed into a "C" shape to fully expose the intervertebral space. If the child is restless and resistant during the puncture process, it will not only increase the difficulty of maintaining the body position, leading to puncture failure or repeated puncture, but also increase the child's pain, increase the risk of complications such as infection and tissue damage, and further affect the clinical diagnosis and treatment process and medical safety.

[0004] Therefore, if a puncture assisting device suitable for various puncture scenes (such as lumbar puncture, abdominal puncture, bone puncture, and intravenous puncture) can be designed, especially for the lumbar puncture scene, it can effectively assist the child to obtain and maintain the correct body position, which will significantly improve the success rate and safety of pediatric puncture operation, and has important practical significance and application value for pediatric clinical practice. SUMMARY

[0005] The present application aims to provide a child body position fixing structure and a puncture bed, which can be used for body position fixation when a child performs lumbar puncture, bone puncture, abdominal puncture, intravenous puncture and other operations, and is multi-purpose for a bed, with high clinical practicability.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a child body position fixing structure, comprising a plate frame, a waist plate, a thigh plate, a calf plate and a head plate, the head plate is rotatably arranged at one end of the waist plate, the thigh plate is rotatably arranged at the other end of the waist plate, and the end of the calf plate is rotatably connected with the end of the thigh plate away from the waist plate; a leg restraint belt is arranged on the thigh plate or the calf plate, a shoulder restraint belt is arranged on the head plate, and a puncture hole and a waist restraint belt are arranged on the waist plate; the waist plate, the thigh plate, the calf plate and the head plate are all installed in the plate frame; the waist plate is fixedly connected with the plate frame, and the end of the plate frame is provided with a rotating shaft; It further comprises a support part for supporting the thigh plate or the calf plate and the head plate in a flat state, and the support part is fixedly arranged on the plate frame; It further comprises a first positioning mechanism for positioning the head plate in a lumbar puncture state, and a second positioning mechanism for positioning the thigh plate and the calf plate in a lumbar puncture state.

[0007] The principle and advantages of the scheme are: when puncturing, the child lies on the child position fixing structure, the head and neck are on the head plate, the waist is on the waist plate, the thigh is on the thigh plate, the lower leg is on the lower leg plate, the leg binding belt is used to bind and fix the child's legs, the waist binding belt is used to bind and fix the waist, and the shoulder binding belt is used to bind the shoulder, so as to avoid the child moving around on the fixing structure. Thus, the child does not need to be manually pressed down during puncturing, and it is suitable for puncturing children.

[0008] The child position fixing structure in the scheme has two states: flat state and lumbar puncture state. In the flat state, the thigh plate, the lower leg plate and the head plate are all flat, the support part supports the thigh plate or the lower leg plate and the head plate, and under the support of the support part, the thigh plate, the lower leg plate and the head plate are in a stable flat state. At this time, the child can be in a supine or prone position on the position fixing structure, so that the child can be punctured, such as abdominal puncture and bone puncture. In the lumbar puncture state, the plate frame can be rotated because the plate frame is provided with a rotating shaft. At this time, the child position fixing structure is rotated from the horizontal state to the vertical state, so that the child becomes a lateral position. Then the head plate, the thigh plate and the lower leg plate are rotated, so that the thigh plate, the waist plate and the head plate form a C shape. In this way, the child's thighs, waist and head and chest on the fixing structure also form a C shape. At this time, the child's waist is punctured through the puncture hole. Therefore, through the scheme, the fixing structure has two states: flat state and lumbar puncture state. The flat state is suitable for puncturing the child in a supine or prone position. The lumbar puncture state is suitable for puncturing the child in a lateral position. At the same time, by making the thigh plate, the waist plate and the head plate form a C shape, the child's posture forms a C shape, which can improve the effect of lumbar puncture.

[0009] No matter whether the child is in a lateral, prone or supine position, the corresponding binding belt binds the part of the child, so that the child does not need to be manually bound, which is simple to operate and does not take much time and effort.

[0010] When in the lumbar puncture state, the head plate and the waist plate have a certain bending angle, the thigh plate and the waist plate have a certain bending angle, and the lower leg plate and the thigh plate have a certain bending angle. The first positioning mechanism can position and fix the head plate, and the second positioning mechanism can position and fix the thigh plate and the lower leg plate. In this way, the head plate and the thigh plate do not rotate freely, so that the head plate, the thigh plate and the waist plate can stably form a C shape, and the child's posture can remain in a C shape.

[0011] Preferably, as an improvement, the first positioning mechanism comprises a first positioning rod and a first plug, one end of the first positioning rod is rotatably connected to the plate frame, the other end of the first positioning rod is provided with a first insertion hole, and the head plate is provided with a second insertion hole; when the head plate is in the lumbar puncture state, the first plug is inserted into the first insertion hole and the second insertion hole. Thus, when the lumbar puncture is performed, the head plate is rotated, then the first plug is inserted into the first insertion hole and the second insertion hole, and the first positioning rod connects the head plate and the plate frame together, so that the head plate cannot be rotated and is locked and positioned.

[0012] Preferably, as an improvement, the inner wall of the plate frame is provided with a sliding groove in the length direction of the plate frame, and a sliding shaft is fixedly arranged on the calf plate and slidably arranged in the sliding groove. Thus, when the thigh plate is bent, the calf plate is bent along with the thigh plate, and the sliding shaft on the calf plate slides in the sliding groove, so that the calf plate does not completely separate from the plate frame during the bending process. At the same time, when the calf plate and the thigh plate are in the flat state, the sliding shaft abuts against the inner wall of the sliding groove, and the calf plate can be supported and can be in a stable horizontal state and will not be rotated downward to the lower side of the plate frame.

[0013] Preferably, as an improvement, the second positioning mechanism comprises a second positioning rod and second plugs fixedly connected to both ends of the second positioning rod, the thigh plate is provided with a third insertion hole, and the calf plate is provided with a fourth insertion hole; when the thigh plate and the calf plate are in the puncture state, the second plugs at both ends of the second positioning rod are respectively inserted into the third insertion hole and the fourth insertion hole. Thus, when the lumbar puncture is performed, the thigh plate and the calf plate are rotated, then the second plugs at both ends of the second positioning rod are respectively inserted into the third insertion hole and the fourth insertion hole, and the second positioning rod connects the thigh plate and the calf plate together, and since the sliding shaft is located in the sliding groove and abuts against the inner wall of the sliding groove, the calf plate and the thigh plate are limited to each other and cannot be freely moved. After the calf plate and the thigh plate are bent, the legs of the child can be in a bent posture, which is beneficial to the child to make a C-shaped posture.

[0014] Preferably, as an improvement, gaps are provided at the connection between the head plate and the waist plate, the connection between the waist plate and the thigh plate, and the connection between the thigh plate and the calf plate; and gap blocking pads are arranged at the gaps. The gap blocking pads are used to cover the gaps at the connection between the head plate and the waist plate, the connection between the waist plate and the thigh plate, and the connection between the thigh plate and the calf plate, so as to avoid the gaps at the connection between the head plate and the waist plate, the connection between the waist plate and the thigh plate, and the connection between the thigh plate and the calf plate from clamping the skin of the child, and improve the safety in use. Or, the upper side of the head plate, the waist plate, the thigh plate and the calf plate are all paved with flexible pads, so that the flexible pads are relatively soft, the children lying on the children body position fixing structure are more comfortable, and the flexible pads can also cover the gaps between the head plate and the waist plate, the gaps between the waist plate and the thigh plate, and the gaps between the thigh plate and the calf plate, so as to avoid the gaps between the head plate and the waist plate, the gaps between the waist plate and the thigh plate, and the gaps between the thigh plate and the calf plate from clamping the skin of the children, and improve the safety in use.

[0015] A children puncture bed comprises the children body position fixing structure, a bed leg, a bed end plate and a lateral lying support plate, the bed end plate is fixed at the end of the lateral lying support plate, and a plate frame is rotationally connected to the bed end plate through a rotating shaft. The plate frame is rotationally connected to the bed end plate through a rotating shaft, and the children body position fixing structure can be turned on the puncture bed. When the children body position fixing structure is in a horizontal state, the children can be in a supine state and a prone state on the children body position fixing structure, and the children are punctured. When the children body position fixing structure is in a vertical state, the children on the children body position fixing structure are in a lateral lying state, and the lateral lying support plate supports the children, so that the children can be punctured in the lumbar vertebra.

[0016] Preferably, as an improvement, a third positioning mechanism is further included, the third positioning mechanism comprises a third positioning rod and a third plug, one end of the third positioning rod is rotationally connected to the bed end plate, the other end of the third positioning rod is provided with a fifth insertion hole, and the end of the plate frame is provided with a sixth insertion hole; and the third plug is inserted into the fifth insertion hole and the sixth insertion hole during the lumbar puncture.

[0017] Therefore, during the lumbar puncture, the children body position fixing structure is in a vertical state, the third plug is inserted into the fifth insertion hole and the sixth insertion hole, the third positioning rod positions the plate frame, so that the children body position fixing structure is in a stable vertical state and cannot be turned back to the original position.

[0018] Preferably, as an improvement, the waist plate comprises a waist fixing plate and a waist sliding plate, the waist fixing plate is fixedly connected to the plate frame, the waist sliding plate is slidingly connected to the waist fixing plate, and the head plate is rotationally connected to the waist sliding plate. Therefore, the length of the waist plate is adjusted by sliding the waist sliding plate on the waist fixing plate.

[0019] Preferably, as an improvement, the thigh plate comprises a thigh fixing plate and a thigh sliding plate, the thigh sliding plate is slidingly connected to the thigh fixing plate, and the calf plate is rotationally connected to the thigh sliding plate. Therefore, the length of the thigh fixing plate is adjusted by sliding the thigh sliding plate on the thigh fixing plate.

[0020] By adjusting the length of the thigh fixing plate and the length of the waist plate, the child body position fixing structure can be adapted to children of different heights, and the child body position fixing structure can be adapted to a wider range of children, reducing the height limit of children.

[0021] Preferably, as an improvement, a gap shielding pad is also arranged at the connection between the plate frame and the lateral lying support plate. Thus, the gap shielding pad can shield the gap at the connection between the plate frame and the lateral lying support plate, avoiding the gap from pinching the skin of the child, and improving the safety of use.

[0022] Preferably, as an improvement, a flexible belt hole is arranged on the waist fixing plate, a flexible belt is fixedly connected in the flexible belt hole, and the puncture hole is located on the flexible belt hole. The flexible belt has a certain flexibility. When the lumbar puncture is performed, the body position of the child is bent into a C shape, the back of the waist is arched, and the flexible belt can be appropriately deformed, so that the back of the waist can be bent and arched.

The first layer is provided with a long strip of small and soft fibers on the surface, and the second layer is provided with a long strip of relatively hard and hooked bristles on the surface. The surface of the first layer provided with small and soft fibers and the surface of the second layer provided with bristles are bonded. By changing the bonding position of the first layer and the second layer, the degree of overlap of the first layer and the second layer is changed, thereby adjusting the length of the binding belt. In this embodiment, the waist binding belt 25, the chest binding belt 26, the thigh binding belt 11, the calf binding belt 12 and the shoulder binding belt 10 are fixed to the corresponding plates by bonding or pegging. Of course, when pegging, a belt slot is provided on the corresponding plate for the binding belt to pass through. In other embodiments, the waist binding belt 25, the chest binding belt 26, the thigh binding belt 11, the calf binding belt 12 and the shoulder binding belt 10 can be provided in multiple to fix different parts of the human body or to adapt to children of different heights. In addition, the headrest 9 is bonded or fixed to the head part 1 by screws. The head part 1 is bonded with a soft pad to increase the softness of the head part 1.

[0032] Both ends of the plate frame 8 are fixedly provided with rotating shafts, which are welded. The rotating shafts are located at the two ends of the side of the plate frame 8 close to the side-lying support plate 5, and are rotatably connected to the bed end plate 6 by bearings. As shown in Figure 4 As shown in

[0033] The child body position fixing structure further comprises a support part for supporting the thigh part plate 3 or the calf part plate 4 and the head part plate 1 in a flat state, and the support part is connected with Figure 2 As shown in the figure, the support part is a plurality of support rods 21, which are fixed on the plate frame 8 by welding. In this embodiment, the number of the support rods 21 is two, which are respectively fixed on the side of the plate frame 8 away from the head part plate 1 and the side of the plate frame 8 away from the thigh part plate 3.

[0034] The support part is connected with Figure 2 As shown in the figure, the child body position fixing structure further comprises a first positioning mechanism for positioning the head part plate 1 in a lumbar puncture state, and a second positioning mechanism for positioning the thigh part plate 3 and the calf part plate 4 in a lumbar puncture state. The first positioning mechanism comprises a first positioning rod 17 and a first positioning rod 17 first pin, and the second positioning mechanism comprises a second positioning rod 15 and a second positioning rod 15 second pin. Figure 1 As shown in the figure, the plate frame 8 is provided with a first rod groove for placing the first positioning rod 17, and the first rod groove is located on the left side of the head part plate 1. One end of the first positioning rod 17 is rotatably connected in the first rod groove, and the other end of the first positioning rod 17 is provided with a first insertion hole. The first positioning rod 17 is connected with Figure 2 As shown in the figure, the side of the head part plate 1 facing the plate frame 8 is provided with a second insertion hole 18. When the head part plate 1 is in a lumbar puncture state, the head part plate 1 is rotated to the position as Figure 2 As shown in the figure, the first positioning rod 17 is pulled out of the first rod groove, and the first insertion hole at the end of the first positioning rod 17 and the second insertion hole 18 on the side of the head part plate 1 are fixed by the first pin (the first pin is inserted in the first insertion hole and the second insertion hole 18 at the same time), so as to realize the locking of the head part plate 1 and the plate frame 8, and the head part plate 1 cannot be rotated. The number of the second insertion holes 18 on the head part plate 1 is multiple, and the first pin is inserted in different second insertion holes 18, so as to realize the locking of the head part plate 1 at different angles.

[0035] The second positioning mechanism comprises a second positioning rod 15 and a second pin welded on both ends of the second positioning rod 15. The side of the thigh part plate 3 facing the plate frame 8 is provided with a third insertion hole, and the side of the calf part plate 4 facing the plate frame 8 is provided with a fourth insertion hole 16. When the thigh part plate 3 and the calf part plate 4 are in a puncture state, the thigh part plate 3 and the calf part plate 4 are rotated to the position as Figure 2In the shown state, the second positioning rod 15 is taken and the second insertion pin at both ends of the second positioning rod 15 is respectively inserted into the third insertion hole and the fourth insertion hole 16, so that the restraint of both the thigh plate 3 and the calf plate 4 is realized, and the thigh plate 3 and the calf plate 4 cannot automatically move when the sliding shaft 20 abuts against the inner wall of the sliding groove 19. In the embodiment, the number of the fourth insertion hole 16 is multiple, and by inserting the second insertion pin into different fourth insertion holes 16, the locking of different bending angles of the thigh plate 3 and the calf plate 4 can be realized. It is worth noting that the setting of the sliding groove 19 and the sliding shaft 20 plays a certain role in the locking of the thigh plate 3 and the calf plate 4. If there is no cooperation between the sliding shaft 20 and the sliding groove 19, even if the thigh plate 3 and the calf plate 4 are connected together through the second positioning rod 15, the relative rotation between the thigh plate 3 and the calf plate 4 will not occur, but the thigh plate 3 will rotate on the waist plate 2.

[0036] In the embodiment, the connection between the head plate 1 and the waist plate 2, the connection between the waist plate 2 and the thigh plate 3, and the connection between the thigh plate 3 and the calf plate 4 are all provided with (the setting mode can be bonding or fixed by screws) gap blocking pads (not shown in the figure), which are flexible pads, such as rubber foam, TPE foam, PVC foam, EVA, latex pad, NBR pad, etc. The gap blocking pads can block the gaps between the head plate 1 and the waist plate 2, the gaps between the waist plate 2 and the thigh plate 3, and the gaps between the thigh plate 3 and the calf plate 4, to avoid pinching the child's body skin. Of course, the gap blocking pads can not be provided, and flexible pads such as rubber foam, TPE foam, PVC foam, EVA, latex pad, NBR pad, etc. can be directly laid on the upper side surfaces of the head plate 1, the waist plate 2, the thigh plate 3 and the calf plate 4. In this way, the child lies on the flexible pad which is soft and comfortable, and the flexible pad can also block the gaps between the head plate 1 and the waist plate 2, the gaps between the waist plate 2 and the thigh plate 3, and the gaps between the thigh plate 3 and the calf plate 4, to avoid pinching the child's body skin.

[0037] The puncture bed further comprises a third positioning mechanism, which comprises a third positioning rod 24 and a third plug. The bed end plate 6 is provided with a second rod groove, one end of the third positioning rod 24 is rotationally connected in the second rod groove, the other end of the third positioning rod 24 is provided with a fifth plug hole, and the end of the plate frame 8 is provided with a sixth plug hole. When performing lumbar puncture, the plate frame 8 is in a vertical state, the third positioning rod 24 is taken out of the second rod groove, and the third plug is inserted into the fifth plug hole and the sixth plug hole, so that the third positioning rod 24 and the plate frame 8 are locked. In this way, the third positioning rod 24 supports the plate frame 8, the plate frame 8 cannot be reset by reverse rotation, and the stability of the plate frame 8 in the vertical state is improved. The connection between the plate frame 8 and the lateral lying support plate 5 is also provided with a gap shielding pad. The gap shielding pad can shield the gap between the plate frame 8 and the lateral lying support plate 5, so that the child's body is not clamped between the side edge of the plate frame 8 and the side edge of the lateral lying support plate 5.

[0038] The specific implementation process is as follows: the puncture bed in this embodiment has two states: flat lying and lumbar puncture. In the flat lying state, as shown in Figure 1 , the child body position fixing structure is in a flat lying state, as shown in Figure 5 , the bed end plate 6 is welded or integrally fixed with a support bar 22, and the plate frame 8 is supported on the support bar 22, so that the child body position fixing structure can stably be in a flat lying state. When puncturing, the child lies on the child body position fixing structure, the head is on the head plate 1 and lies on the headrest 9, the waist is on the waist plate 2, the thigh is on the thigh plate 3, the lower leg is on the lower leg plate 4, the thigh restraint belt 11 and the lower leg restraint belt 12 respectively restrain and fix the thigh and the lower leg, the waist restraint belt 25 restrains and fixes the waist, and the shoulder restraint belt 10 restrains the shoulder, so that the child can be restrained on the child body position fixing structure, so that the child does not need to be manually pressed when puncturing. At this time, the child on the fixing structure can be in a supine or prone position, so that the child can be punctured in the chest and the bone.

[0039] If it is necessary to perform lumbar puncture on the child, it is necessary to change the flat lying state of Figure 1 to the lumbar puncture state of Figure 2 . At this time, the plate frame 8 is manually pushed upward, the plate frame 8 drives the entire child puncture fixing structure to rotate from a horizontal state to a vertical state, so that the child becomes a lateral lying state, and the side of the child is on the lateral lying support plate 5. Then the third positioning rod 24 is locked and fixed to the plate frame 8, and the entire child puncture plate is in a stable vertical state.

[0040] Then the head plate 1, the thigh plate 3 and the lower leg plate 4 are manually rotated, the head plate 1 is rotated to Figure 2After the posture, the head plate 1 and the plate frame 8 are fixed together by using the first positioning rod 17, so that the head and chest of the child is in a state of bending towards the waist direction. The thigh plate 3 and the calf plate 4 are rotated to Figure 2 After the posture, the thigh plate 3 and the calf plate 4 are fixed together by using the second positioning rod 15, so that the thigh is in a state of bending towards the waist direction, and the calf and the thigh are also in a state of bending.

[0041] After the lumbar puncture, the first positioning rod 17 and the second positioning rod 15 are removed, and the head plate 1, the thigh plate 3 and the calf plate 4 are no longer positioned, and the head plate 1, the thigh plate 3 and the calf plate 4 are manually rotated in the reverse direction to reset the head plate 1, the thigh plate 3 and the calf plate 4, and the third positioning rod 24 is removed from the plate frame 8, and the third positioning rod 24 no longer positions the plate frame 8, and the child body position fixing structure in Figure 2 is rotated to the flat state of Figure 1 .

[0042] Embodiment 2 This embodiment is improved on the basis of embodiment 1. The waist plate 2 of this embodiment is provided with a flexible belt hole, and a flexible belt 23 such as a latex pad or cloth is fixed in the flexible belt hole by screwing, bonding or lacing. The puncture hole 31 is located on the flexible belt 23. The reason for such arrangement is that the back of the waist of the body is in a "C" shape during the lumbar puncture, and the flexible belt 23 is not made of hard material, but can arch outward according to the bending radius of the waist, so as to have a certain bending amplitude to enable the waist to bend normally.

[0043] Embodiment 3 This embodiment is further improved on the basis of embodiment 1 or embodiment 2. The waist plate 2 and the thigh plate 3 in embodiments 1-2 cannot be adjusted in length. In this embodiment, the waist plate 2 includes a waist fixing plate 201 and a waist sliding plate 202, the waist fixing plate 201 is fixedly connected to the plate frame 8, and the waist sliding plate 202 is slidably connected to the waist fixing plate 201. The specific sliding mode is that the waist fixing plate 201 is provided with a plate cavity, one end of the waist sliding plate 202 is inserted into the plate cavity and can slide in the plate cavity, and the other end of the waist sliding plate 202 extends out of the plate cavity. At this time, the head plate 1 is rotatably connected to the waist sliding plate 202. The puncture hole 13 is located on the waist fixing plate 201. In this way, by sliding the waist sliding plate 202 on the waist fixing plate 201, the length adjustment of the waist plate 2 is realized.​

[0044] In addition, it is easy to understand that the side of the waist fixing plate 201 is provided with a plurality of positioning holes (not shown), and the side of the waist sliding plate 202 is provided with a plurality of threaded holes. After the waist sliding plate 202 slides, the threaded holes and different positioning holes are opposite, and then a bolt is screwed into the threaded hole through the positioning hole, so that the fixation of the waist sliding plate 202 and the waist fixing plate 201 after the sliding adjustment of the waist sliding plate 202 is realized. In this embodiment, the movement of the waist sliding plate 202 drives the head plate 1 to move together.

[0045] Similarly, the thigh plate 3 includes a thigh fixing plate 301 and a thigh sliding plate 302, and the thigh sliding plate 302 is slidingly connected to the thigh fixing plate 301. The sliding connection of the thigh sliding plate 302 to the thigh fixing plate 301 is as follows: the thigh fixing plate 301 is provided with a plate cavity, one end of the thigh sliding plate 302 is inserted into the plate cavity and can slide in the plate cavity, and the other end of the thigh sliding plate 302 extends out of the plate cavity. At this time, the calf plate 4 is rotationally connected to the thigh sliding plate 302. In this way, the length adjustment of the thigh plate 3 is realized by sliding the thigh sliding plate 302 on the thigh fixing plate 301. In this embodiment, the movement of the thigh sliding plate 302 drives the calf plate 4 to move together.

[0046] In addition, it is easy to understand that the side of the waist fixing plate 201 is provided with a plurality of positioning holes (not shown), and the side of the waist sliding plate 202 is provided with a plurality of threaded holes. After the waist sliding plate 202 slides, the threaded holes and different positioning holes are opposite, and then a bolt is screwed into the threaded hole through the positioning hole, so that the fixation of the waist sliding plate 202 and the waist fixing plate 201 after the sliding adjustment of the waist sliding plate 202 is realized. In this embodiment, the movement of the waist sliding plate 202 drives the head plate 1 to move together.

[0047] In this way, after the length adjustment of the thigh plate 3 and the waist plate 2, the child body position fixing structure can be used for children of different heights, and the application range is wider.
