Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a restraint belt for children's stomatological surgery. Background Art

[0002] In the field of stomatology, there have always been many challenges in treating pediatric patients. Children are in the growth and development stage and often lack sufficient knowledge of oral treatment. When faced with surgical instruments and unfamiliar environments, they are prone to strong fear and resistance. This makes it extremely difficult for them to remain quiet and cooperate during the operation, and they often make large body movements and shake their heads.

[0003] Traditional restraint methods are mostly simple and crude, such as relying solely on manual fixation by medical staff or parents, which not only consumes a lot of manpower, but also has unstable fixation effects. In actual operation, medical staff use flexible restraint belts to tie the child's head, hands and feet to the operating table. This operation is relatively rough, making the child more likely to resist. At the same time, the child's neck usually shakes a lot, and traditional restraint belts are difficult to restrain the child's neck. If the child is restrained with a flexible restraint belt, it is easy to cause the child to suffocate.

[0004] In summary, how to solve the problem that during pediatric dental surgery, when medical staff use flexible restraint belts to tie the child's head, hands and feet to the operating table, the child's neck usually shakes greatly, and traditional restraint belts are difficult to restrain the child's neck. If the flexible restraint belt is used, the child may easily cause the risk of suffocation. This has become a difficult problem that needs to be urgently solved in this field. Therefore, it is necessary to propose a pediatric dental surgery restraint belt. Summary of the invention

[0005] To solve the above problems, the present invention provides a pediatric oral surgery restraint belt, which is used to effectively fix the head and neck of the child, can reduce the shaking of the child's head during surgery, and can also fine-tune the direction of the child's head, thereby providing medical staff with a more precise operating field of view and conditions.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a pediatric oral surgery restraint belt comprises a controller and head restraint belts symmetrically and fixedly connected to both sides of a headrest of a dental comprehensive treatment table; adjacent head restraint belts are detachably connected by Velcro; and a neck fixing component is provided on the dental comprehensive treatment table to prevent the child's head from shaking left and right during surgery.

[0007] The neck fixation assembly includes a shoulder support, a "C"-shaped upper neck fixation ring and a lower neck fixation ring, wherein the shape of the upper neck fixation ring close to the front of the child's lower jaw is as follows: starting from the position where it fits with the neck, within a range of 5 cm in front of the lower jaw, the width decreases from 3 cm to 1 cm; the top of the shoulder support and the bottom of the lower neck fixation ring are fixedly connected, and the top of the lower neck fixation ring is fixedly connected with a plurality of first U-shaped blocks along its circumference, the inner side walls of the first U-shaped blocks are hinged with a first frame, and an electric push rod is hinged inside the first frame.

[0008] A plurality of second U-shaped blocks are fixedly connected to the bottom of the upper neck fixing ring along its circumference. The second U-shaped blocks and the first U-shaped blocks are arranged alternately. The inner walls of the second U-shaped blocks are hinged with second frames. The output shafts of the electric push rods are hinged to the inner sides of the second frames adjacent to them. The controller is used to control the extension and retraction of the output shafts of the electric push rods, thereby adjusting the distance between the upper neck fixing ring and the lower neck fixing ring.

[0009] Lock rods are hinged at both ends of the upper neck fixing ring and the lower neck fixing ring, and quick-release lock buckles are fixedly connected to the lock rods. Adjacent lock rods are detachably connected via the quick-release lock buckles.

[0010] The technical principles of the above scheme are as follows:

[0011] The head restraint is detachably connected to both sides of the headrest of the dental comprehensive treatment table through Velcro, which can initially fix the child's head from both sides to limit its large-scale rotation. Then the neck fixation component is worn on the child's neck. The shoulder support of the neck fixation component is used to support the child's shoulder. When the controller controls the electric push rod output shaft to extend and retract, the second U-shaped block and the first U-shaped block are staggered, which will drive the second frame to move, thereby realizing the change of the distance between the upper neck fixing ring and the lower neck fixing ring, which can provide support between the child's lower jaw and shoulders. At the same time, it can be accurately adjusted according to the thickness of the child's neck, tightly fit the neck, and prevent the child's head from shaking left and right during the operation. When it is necessary to fine-tune the direction of the child's head, the controller accurately controls the extension and retraction of the electric push rod output shaft, driving the relative position change between the upper neck fixing ring and the lower neck fixing ring, thereby realizing a subtle adjustment of the child's head angle.

[0012] The above scheme has the following beneficial effects:

[0013] 1. The present invention can effectively fix the head and neck of the child through the synergistic effect of the head restraint and the neck fixing component; the head restraint limits the child's head from rotating significantly, and the neck fixing component further prevents the head from shaking left and right, thereby reducing the shaking amplitude of the child's head during surgery and improving the stability of the surgical operation.

[0014] 2. The neck fixation component of the present invention can be precisely adjusted according to the thickness of the child's neck, closely fitting the neck, thereby enhancing the fixation effect, improving the comfort of the child during the operation, reducing the additional pain caused to the child by improper restraint, and helping to alleviate the child's fear, making it easier for the child to cooperate with the operation.

[0015] 3. The present invention uses a controller to accurately control the extension and retraction amount of the electric push rod output shaft, thereby achieving subtle adjustment of the angle of the child's head, providing medical staff with a more accurate operating field and conditions. Medical staff can observe the surgical site more clearly and accurately operate surgical instruments, thereby improving the accuracy and success rate of the operation. At the same time, it can also shorten the operation time and reduce the pain and fear of the child.

[0016] Furthermore, the inner side walls of the upper neck fixing ring and the lower neck fixing ring are both arc-shaped.

[0017] Beneficial effect: The curved inner wall design can better fit the physiological curve of the child's neck and improve the comfort of the child when wearing it.

[0018] Furthermore, airbags are fixedly connected to the inner walls of the upper neck fixing ring and the lower neck fixing ring, and the lower neck fixing ring is provided with an inflation component for inflating the airbag and an attraction component for attracting the child's attention during the operation.

[0019] Beneficial effects: After the airbag is inflated, it can be adaptively adjusted according to the actual shape of the child's neck, further optimizing the fit, providing a more uniform pressure distribution, and effectively reducing the local pressure. At the same time, after the airbag is inflated, it can fit closely to the child's neck, increasing the effect of fixing the child's neck. The attraction component can distract the child's attention during the operation, reduce his fear of the surgical environment and resistance to the treatment operation, and make the operation smoother.

[0020] Furthermore, the attraction component includes an L-shaped support rod and a ball-kicking doll, and the right calf and right thigh of the ball-kicking doll are hinged.

[0021] One end of the L-shaped support rod is rotatably matched with the top of the lower neck fixing ring, the other end of the L-shaped support rod is fixedly connected with a base plate, the top of the base plate is fixedly connected with a driving member and a power box, and the left calf of the kicking doll is fixedly connected with the top of the power box.

[0022] A slide groove is opened on the top of the power box, and the output shaft of the driving member passes through the side wall of the power box and extends into the power box and is coaxially fixedly connected with the first turntable. A first connecting rod is eccentrically fixedly connected to the first turntable, and a first pull rod is rotatably engaged with the first connecting rod. The first pull rod passes through the slide groove and slides with the slide groove. One end of the first pull rod is away from the first connecting rod and is hinged to the bottom of the right calf of the kicking ball doll.

[0023] The first connecting rod is eccentrically fixedly connected to the second turntable at one end away from the first turntable, and the second connecting rod is eccentrically fixedly connected to the side wall of the second turntable away from the first connecting rod. A sliding block is rotatably engaged on the second connecting rod, and a rectangular ring is slidably engaged on the sliding block. A second pull rod is fixedly connected to the top of the rectangular ring, and the second pull rod passes through the top wall of the power box and vertically slides with the top wall of the power box. A toy football is fixedly connected to the end of the second pull rod away from the rectangular ring, and the toy football is located above the right calf of the kicking doll.

[0024] The end of the second connecting rod away from the second rotating disk is eccentrically fixedly connected to the third rotating disk, and the side of the third rotating disk away from the second connecting rod is coaxially fixedly connected to the rotating shaft.

[0025] Beneficial effect: when the driving member is started, its output shaft drives the first turntable to rotate. Since the first connecting rod is eccentrically fixed on the first turntable, as the first turntable rotates, the first connecting rod performs a circular motion, and then drives the right calf of the kicking doll to swing back and forth around the hinge point between the first connecting rod and the left calf through the first pull rod, simulating the kicking action. At the same time, the first connecting rod drives the second turntable to rotate, and the second turntable drives the slider to slide in the rectangular ring through the second connecting rod. The movement of the slider drives the toy football to move up and down through the second pull rod, so that the toy football presents a dynamic effect of ups and downs above the right calf of the kicking doll. This dynamic kicking scene can attract the attention of the child and make the child focus on the kicking doll and the toy football, thereby effectively distracting the child's attention during the operation, reducing his fear of the operating environment and resistance to treatment operations, making the operation smoother.

[0026] Furthermore, the inflation assembly includes a piston cylinder fixedly connected to a side wall of the power box, a piston is slidably fitted on the inner wall of the piston cylinder, and a piston rod is fixedly connected to the bottom of the piston; a rotating shaft passes through the side wall of the power box and is coaxially fixedly connected to a wheel disk, a crank is eccentrically hinged on the wheel disk, and the crank is hinged to the piston rod at one end away from the wheel disk; an air inlet pipe and an air outlet pipe are connected to the piston cylinder, and both the air inlet pipe and the air outlet pipe are connected to a one-way valve, and the air outlet pipe and the air bag are connected.

[0027] Beneficial effect: The third turntable drives the rotating shaft to rotate, and then drives the wheel to rotate. Since the crank is hinged on the wheel, the rotation of the wheel causes the crank to move in a circle, and then drives the piston to move back and forth in the piston cylinder through the piston rod. When the piston moves downward, the one-way valve in the air inlet pipe opens, and the outside air enters the piston cylinder; when the piston moves upward, the one-way valve in the air outlet pipe opens, and the air in the piston cylinder is pressed into the airbag to inflate the airbag. This design uses the power generated by the operation of the driving parts in the power box to drive the inflation component, without the need for additional inflation equipment, and simplifies the overall structure.

[0028] Furthermore, pressure sensors are fixedly connected to the side walls of the airbags, and the controller is used to receive pressure signals from the pressure sensors and control the driving component to stop running based on the pressure signals.

[0029] Beneficial effect: The controller is used to receive the pressure signal of the pressure sensor, and control the driving component to stop running based on the pressure signal. When the pressure reaches the preset value, the inflation component stops working to prevent the airbag from excessively squeezing the child's neck.

[0030] Furthermore, massage balls are rotatably mounted on the side walls of the electric push rod.

[0031] Beneficial effects: During the operation of the electric push rod, the massage ball can gently massage both sides of the child's neck to further relieve the child's tension.

[0032] Furthermore, a sponge layer is fixedly connected to the bottom of the shoulder support.

[0033] Beneficial effect: The sponge layer makes the shoulder support softer and more comfortable when supporting the child's shoulders, reducing the discomfort caused by lying down for a long time.

[0034] Furthermore, the upper neck fixing ring and the lower neck fixing ring are both made of aluminum alloy material.

[0035] Beneficial effects: Aluminum alloy material is light and strong, which reduces the overall weight while ensuring stability, reduces the extra burden on the child's neck, and improves the comfort of the child when wearing it. In addition, aluminum alloy also has good corrosion resistance, which can ensure that the upper and lower neck fixing rings are not easily damaged during long-term use, thus extending their service life.

[0036] Furthermore, the inside of the head restraints are coated with an aromatherapy coating.

[0037] Beneficial effects: The aromatherapy coating contains a variety of natural plant aromas, such as lavender and chamomile, which can continuously release mild fragrance, regulate the emotions of children through the olfactory nerves, and to a certain extent help them stay relaxed during the operation.

DETAILED DESCRIPTION

[0046] The following is a detailed description of the specific implementation method:

[0047] Embodiment 1:

[0048] As attached Figure 1 , Figure 3 and Figure 6 As shown: a pediatric surgical restraint belt in the dental department, including head restraint belts symmetrically and fixedly connected to both sides of the headrest of the dental comprehensive treatment table, and also including a controller; Velcro is sewn on the head restraint belts, and adjacent head restraint belts are detachably connected by Velcro; the dental comprehensive treatment table is provided with a neck fixing component for preventing the child's head from shaking left and right during surgery.

[0049] The neck fixation assembly includes a shoulder support 1, an upper neck fixation ring 2 and a lower neck fixation ring 3 in a "C" shape, wherein the shape of the upper neck fixation ring 2 close to the front of the child's lower jaw is as follows: starting from the position where it fits with the neck, within a range of 5 cm from the front of the lower jaw, the width decreases from 3 cm to 1 cm; the inner side walls of the upper neck fixation ring 2 and the lower neck fixation ring 3 are both arc-shaped, the top of the shoulder support 1 and the bottom of the lower neck fixation ring 3 are fixedly connected by screws, and a plurality of first U-shaped blocks 4 are integrally formed along the circumference of the top of the lower neck fixation ring 3, the inner side walls of the first U-shaped blocks 4 are hinged with first frames 5, and electric push rods 6 are hinged inside the first frames 5.

[0050] A plurality of second U-shaped blocks 7 are integrally formed along the circumference of the bottom of the upper neck fixing ring 2. The second U-shaped blocks 7 and the first U-shaped blocks 4 are arranged alternately. The inner walls of the second U-shaped blocks 7 are hinged with second frames 8. The output shafts of the electric push rods 6 are hinged to the inner sides of the second frames 8 adjacent thereto. The controller is used to control the extension and retraction of the output shafts of the electric push rods 6, thereby adjusting the distance between the upper neck fixing ring 2 and the lower neck fixing ring 3.

[0051] Lock rods 9 are hinged at both ends of the upper neck fixing ring 2 and the lower neck fixing ring 3 , and quick-release lock buckles 10 are fixedly connected to the lock rods 9 by screws. Adjacent lock rods 9 are detachably connected by the quick-release lock buckles 10 .

[0052] Airbags are fixedly bonded to the inner walls of the upper neck fixing ring 2 and the lower neck fixing ring 3. An L-shaped support rod 11 is provided on the top of the lower neck fixing ring 3. One end of the L-shaped support rod 11 is rotatably matched with the top of the lower neck fixing ring 3. The other end of the L-shaped support rod 11 is fixedly connected to a base plate 13 by screws. The top of the base plate 13 is fixedly connected to a power box 15 by screws. The base plate 13 is provided with an inflation component for inflating the airbag and an attraction component for attracting the patient's attention during the operation.

[0053] The inflation assembly includes a piston cylinder 26 fixedly connected to a side wall of the power box 15 by screws, and a first drive member 30 fixedly connected to the base plate 13 by screws, and the controller is used to control the rotation of the output shaft of the first drive member 30; in this embodiment, the first drive member 30 is a DC reduction motor; the inner wall of the piston cylinder 26 is slidably fitted with a piston, and a piston rod 27 is integrally formed at the bottom of the piston; the output shaft of the DC reduction motor is coaxially fixedly connected to a wheel disc 28 by screws, and a crank 29 is eccentrically hinged on the wheel disc 28, and the crank 29 is hinged to the piston rod 27 at one end away from the wheel disc 28; the piston cylinder 26 is connected to an air inlet pipe and an air outlet pipe, and both the air inlet pipe and the air outlet pipe are connected to a one-way valve, and the air outlet pipe and the air bag are connected.

[0054] Pressure sensors are fixedly bonded to the side walls of the airbags. The controller is used to receive pressure signals from the pressure sensors and control the DC reduction motor to stop running based on the pressure signals.

[0055] The specific implementation process is as follows:

[0056] by Figure 1 For example, the medical staff first guides the child to the dental comprehensive treatment table, lets the child lie flat on the treatment table, and adjusts the appropriate lying posture. Pick up the upper neck fixing ring 2 and the lower neck fixing ring 3, open the quick release lock buckle 10, and unfold all the locking rods 9, then place the lower neck fixing ring 3 under the child's neck, and then place the upper neck fixing ring 2 above the child's neck, ensuring that the shoulder support 1 is placed on the child's shoulder.

[0057] During oral surgery, the doctor needs to perform all-round operations on the child's oral cavity, and the upper neck fixing ring 2 and the lower neck fixing ring 3 should avoid blocking the area around the oral cavity. Therefore, the present invention optimizes the shape of the upper neck fixing ring 2 and the lower neck fixing ring 3 so that they can fix the neck while leaving enough space for oral operations. The present invention designs the front ends of the upper neck fixing ring and the lower neck fixing ring to be narrower in shape to reduce the coverage of the front of the child's lower jaw.

[0058] After adjusting the position, the medical staff connects the adjacent locking rods 9 through the quick-release lock buckle 10 to fix the upper neck fixing ring 2 and the lower neck fixing ring 3 on the neck of the child.

[0059] Next, pull up the head restraints from both sides of the headrest of the dental treatment table and use Velcro to initially fix the child's head. The head restraints can limit the child's head from turning too far.

[0060] by Figure 4 For example, the medical staff uses the controller to control the output shaft of the DC reduction motor to rotate, thereby driving the wheel 28 to rotate. Since the crank 29 is eccentrically hinged on the wheel 28, the rotation of the wheel 28 causes the crank 29 to perform a crank motion. Since the crank 29 and the piston rod 27 are hinged, the crank 29 performs a crank motion, which drives the piston rod 27 and then drives the piston to perform an up and down reciprocating motion in the piston cylinder 26.

[0061] When the piston moves downward, the one-way valve in the air inlet pipe opens, and the outside air enters the piston cylinder 26; when the piston moves upward, the one-way valve in the air outlet pipe opens, and the air in the piston cylinder 26 is pressed into the airbag. After the airbag is inflated, it can be adaptively adjusted according to the actual shape of the child's neck, further optimizing the fit between the airbag and the child's neck, providing a more uniform pressure distribution, effectively reducing the local pressure on the child's neck, and at the same time, the airbag can fit closely to the child's neck after being inflated, increasing the effect of fixing the child's neck.

[0062] Medical staff pre-set a pressure preset value for the controller. The pressure sensor on the side wall of the airbag monitors the pressure of the airbag on the child's neck in real time and transmits the pressure signal to the controller. When the pressure reaches the preset value, the controller controls the DC motor to stop running to prevent the airbag from over-pressing the child's neck.

[0063] by Figure 1 , Figure 3 and Figure 6For example, then, according to the different lengths of the necks of different children, the medical staff starts the electric push rod 6 through the controller. The output shaft of the electric push rod 6 begins to extend and retract. At the same time, because the electric push rod 6 is hinged to the inside of the first frame 5 hinged in the first U-shaped block 4, the output shaft of the electric push rod 6 is hinged to the inside of the second frame 8 hinged in the second U-shaped block 7. The extension and retraction of the output shaft of the electric push rod 6 can drive the upper neck fixing ring 2 to move up and down stably, and the distance between the upper neck fixing ring 2 and the lower neck fixing ring 3 changes accordingly. When the neck of the child is long, all the output shafts of the electric push rods 6 are controlled to extend until the upper neck fixing ring 2 fits tightly against the lower jaw of the child.

[0064] At the same time, since the curve of the line connecting the lower jaw and the back of the neck of each child is different, the medical staff can operate the controller to control the output shaft of the electric push rod 6 in different positions to extend and retract at different distances to adapt to the curve of the lower jaw and the back of the neck of different children. For example, when a child has a lower jaw and a higher back of the neck, the medical staff can use the controller to adjust the output shaft of the electric push rod 6 below the back of the neck to extend and the output shaft of the electric push rod 6 below the lower jaw to retract, so that the upper neck fixing ring 3 is tilted toward the front of the child to further fit the lower jaw curve of different children, thereby providing personalized adjustment and fixation functions according to different children, while also improving the comfort of the children and providing stable support between the lower jaw and shoulders of the children. When the upper neck fixing ring 2 is tightly fitted to the lower jaw of the child, the medical staff uses the controller to stop the operation of all electric push rods 6. At this time, the upper neck fixing ring 2 can limit the child's neck, effectively preventing the child's head from shaking left and right during the operation.

[0065] During the entire operation, medical staff can control the extension and retraction of the output shaft of the electric push rod 6 at different positions through the controller according to the needs of the operation, so as to achieve subtle adjustments to the angle of the child's head, providing medical staff with a more precise operating field of view and conditions, so that medical staff can observe the surgical site more clearly and operate surgical instruments accurately.

[0066] For example, when the child's head needs to be slightly tilted to the right, the controller controls the output shaft of the left half of the electric push rod 6 to extend slightly and the output shaft of the right half of the electric push rod 6 to contract slightly. At this time, the upper neck fixing ring 2 can tilt to the right, thereby driving the child's head to tilt slightly to the right, which can solve the problem that traditional head fixing devices for children are difficult to adjust the angle of the child's head.

[0067] After the operation is completed, the medical staff opens the quick release buckle 10 on the locking rod 9 of the upper neck fixing ring 2 and the lower neck fixing ring 3, and removes the neck fixing assembly from the child's neck. Unfasten the Velcro on the head restraint belt and remove the head restraint belt from both sides of the child's head.

[0068] Embodiment 2:

[0069] As attached Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the difference from Example 1 is that the attraction component includes a ball-kicking doll 12, the right calf and right thigh of the ball-kicking doll 12 are hinged, the right thigh and the bottom of the ball-kicking doll 12 are hinged, and the left calf of the ball-kicking doll 12 and the top of the power box 15 are fixedly connected by screws.

[0070] The top of the bottom plate 13 is also fixedly connected with a second driving member 14 by screws, and the controller is used to control the rotation of the output shaft of the second driving member 14 .

[0071] A slide groove is provided on the top of the power box 15; the output shaft of the second driving member 14 passes through the side wall of the power box 15 and extends into the power box 15 and is coaxially fixedly connected to the first turntable 16 by screws. A first connecting rod 17 is eccentrically integrally formed on the side wall of the first turntable 16 away from the second driving member 14. A first pull rod 18 is rotatably engaged with the first connecting rod 17. The first pull rod 18 passes through the slide groove and slides with the slide groove. One end of the first pull rod 18 away from the first connecting rod 17 is hinged to the bottom of the right calf of the kicking ball doll 12.

[0072] A second turntable 19 is eccentrically integrally formed at one end of the first connecting rod 17 away from the first turntable 16, and a second connecting rod 20 is eccentrically integrally formed on a side wall of the second turntable 19 away from the first connecting rod 17. A slider 21 is rotatably engaged on the second connecting rod 20, and a rectangular ring 22 is slidably engaged on the slider 21. A second pull rod 23 is integrally formed on the top of the rectangular ring 22. The second pull rod 23 penetrates the top wall of the power box 15 and vertically slides with the top wall of the power box 15. The second pull rod 23 is fixedly connected to a toy football 24 at one end away from the rectangular ring 22 by screws. The toy football 24 is located above the right calf of the kicking doll 12.

[0073] A third rotating disk 25 is eccentrically formed in one piece at one end of the second connecting rod 20 away from the second rotating disk 19 . The third rotating disk 25 is rotatably matched with the inner wall of the power box 15 .

[0074] A microphone is fixedly connected to the side wall of the bottom plate 13 by screws. The controller is used to receive the sound signal sent by the microphone and emitted by the dental instrument, and control the operation of the second driving member 14 based on the sound signal.

[0075] The specific implementation process is as follows:

[0076] by Figure 2 , Figure 4 and Figure 5For example, during the operation, when the dental instrument makes a sound, when the controller receives the sound of the surgical instrument sent by the microphone for more than 3S, the controller sends a control signal to control the start of the second drive member 14. In this embodiment, the second drive member 14 is a DC motor; the output shaft of the DC motor drives the first turntable 16 to rotate. Since the first connecting rod 17 is eccentrically fixed on the first turntable 16, as the first turntable 16 rotates, the first connecting rod 17 performs a circular motion. Since the first pull rod 18 and the first connecting rod 17 rotate in coordination, the first pull rod 18 can perform a crank motion, thereby driving the right calf of the kicking doll 12 to swing back and forth up and down around the hinge point between it and the right thigh, simulating the action of bouncing the ball; at the same time, the first connecting rod 17 drives the second turntable 19 to rotate. Since the second connecting rod 20 also rotates with the second turntable 19 is eccentrically fixed, so the rotation of the second turntable 19 can drive the second connecting rod 20, and then drive the rectangular ring 22 to slide left and right and move up and down in the slider 21. Since the second pull rod 23 and the rectangular ring 22 are integrally formed, under the limiting effect of the top wall of the power box 15 on the second pull rod 23 that can only slide vertically, the second pull rod 23 can drive the toy football 24 to move up and down above the right calf of the kicking doll 12. With the cooperation of the toy football 24 and the right calf of the kicking doll 12 swinging back and forth, the kicking doll 12 can simulate the juggling scene, thereby attracting the attention of the child, allowing the child to focus on the kicking doll 12 and the toy football 24, thereby effectively distracting the child's attention during the operation, reducing his fear of the operating environment and resistance to treatment operations, and making the operation smoother.

[0077] Since dental surgery is time-consuming, it is usually performed while the child is awake. Also, since there are many dental surgical instruments, the sound and appearance of the instruments are the main source of anxiety and fear for children undergoing dental surgery. Therefore, the design of the attraction component can shift the child's attention from the dental instruments used by the doctor to the attraction component during the operation, thereby relieving the child's tension and allowing the child to receive surgical treatment in a relatively relaxed and pleasant atmosphere.

[0078] In addition, the continuous suction effect can reduce the child's body movements caused by fear, ensure the safety and accuracy of the surgical operation, avoid interference with the surgical process due to sudden movements of the child, reduce surgical risks, and increase the success rate of the operation. At the same time, it can also reduce the work pressure of medical staff to a certain extent and improve the efficiency of the entire surgical process.

[0079] The attraction component of the present invention is activated by the sound of surgical instruments during dental surgery, which reduces the main source of anxiety and fear in children undergoing dental surgery to a certain extent. Compared with the attention-attracting devices used in traditional pediatric examinations, it reduces the risk that children will lose interest for a period of time due to the single form of the attention-attracting devices, which will cause the children to shift their attention to the surgical instruments again and fall into tension and fear again, which will lead to chaos or non-cooperation during the operation, resulting in the forced interruption of the surgical operation or prolonged operation time.

[0080] Since one end of the L-shaped support rod 11 is rotatably matched with the top of the lower neck fixing ring 3, during surgery, medical staff can rotate the L-shaped support rod 11 to a position away from the child's face to avoid the suction component blocking the child's face and thus affecting the doctor's operation.

[0081] Embodiment 3:

[0082] As attached Figure 1 As shown, the difference from the second embodiment is that massage balls are rotatably fitted on the side walls of the electric push rod 6 .

[0083] The specific implementation process is as follows:

[0084] During the process of extending and contracting the output shaft of the electric push rod 6 to drive the upper neck fixing ring 2 to rise and fall, since the electric push rod 6 and the upper neck fixing ring 2 and the lower neck fixing ring 3 are all hinged, their relative positions with the upper neck fixing ring 2 will change, so that the massage balls on the side walls of the electric push rod 6 will contact the skin of the child's neck. At this time, the massage balls can gently massage both sides of the child's neck to further relieve the child's tension.

[0085] Embodiment 4:

[0086] As attached Figure 1 As shown, the difference from Example 3 is that a sponge layer is fixedly bonded to the bottom of the shoulder support 1.

[0087] The specific implementation process is as follows:

[0088] The sponge layer makes the shoulder support 1 softer and more comfortable when supporting the child's shoulders, thereby reducing the discomfort caused by lying down for a long time.

[0089] Embodiment 5:

[0090] As attached Figure 1 As shown, the difference from Example 4 is that the upper neck fixing ring 2 and the lower neck fixing ring 3 are both made of aluminum alloy material.

[0091] The specific implementation process is as follows:

[0092] Aluminum alloy material has the characteristics of light weight and high strength. While ensuring stability, it reduces the overall weight, reduces the extra burden on the neck of the child, and improves the comfort of the child when wearing it. In addition, aluminum alloy also has good corrosion resistance, which can ensure that the upper neck fixing ring 2 and the lower neck fixing ring 3 are not easily damaged during long-term use, thereby extending their service life.

[0093] Embodiment 6:

[0094] The difference from Example 5 is that the inner side of the head restraint is coated with an aromatherapy coating.

[0095] The specific implementation process is as follows:

[0096] The aromatherapy coating contains a variety of natural plant aromas, such as lavender and chamomile, which can continuously release mild fragrance, regulate the emotions of children through the olfactory nerves, and to a certain extent help them stay relaxed during the operation.

[0097] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the protection scope of the invention.
