Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to pediatric surgical restraints in dentistry. Background Technology

[0002] In the field of oral medicine, treating pediatric patients has always presented numerous challenges. Children are in a stage of growth and development and often lack sufficient understanding of oral treatment. When faced with surgical instruments and an unfamiliar environment, they are prone to strong fear and resistance. This makes it extremely difficult for them to remain calm and cooperative during surgery, often resulting in large-scale limb movements and head shaking.

[0003] Traditional restraint methods are often quite simple and crude, such as relying solely on manual restraint by medical staff or parents. This not only consumes a lot of manpower but also results in inconsistent restraint effectiveness. In practice, medical staff use flexible restraint straps to bind the child's head, hands, and feet to the operating table. This method is rather rough, making the child more likely to resist. At the same time, children's necks usually move quite a bit, making it difficult for traditional restraint straps to effectively restrain their necks. Using flexible restraint straps on children can easily lead to the risk of suffocation.

[0004] In summary, how to address the issue of significant neck movement in pediatric dental surgeries when medical staff use flexible restraints to bind the child's head, hands, and feet to the operating table, making it difficult for traditional restraints to effectively control the neck, and the risk of suffocation when using flexible restraints, has become a pressing problem in this field. Therefore, it is necessary to propose a restraint method for pediatric dental surgeries. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a pediatric surgical restraint belt for dental procedures, which effectively secures the child's head and neck, reducing head movement during surgery and allowing for fine-tuning of the child's head orientation, thus providing medical staff with a more precise field of vision and operating conditions.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a pediatric surgical restraint belt for dentistry, comprising a controller and head restraint belts symmetrically and fixedly connected to both sides of the headrest of the dental treatment table; adjacent head restraint belts are detachably connected by Velcro; the dental treatment table is provided with a neck fixation component to prevent the child's head from swaying 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. The upper neck fixation ring, located near the front of the child's jaw, has a shape where its width decreases from 3 cm to 1 cm within a 5 cm radius from the point where it fits against the neck. The top of the shoulder support and the bottom of the lower neck fixation ring are fixedly connected. Several first U-shaped blocks are fixedly connected to the top of the lower neck fixation ring along its circumference. Each first U-shaped block has a first frame hinged to its inner sidewall, and each first frame has an electric push rod hinged to it.

[0008] Several 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 sidewalls of the second U-shaped blocks are all hinged with second frames. The output shaft of the electric push rod is hinged to the inner side of the adjacent second frame. The controller is used to control the extension and retraction of the output shaft of the electric push rod, thereby adjusting the distance between the upper neck fixing ring and the lower neck fixing ring.

[0009] Both ends of the upper and lower neck fixing rings are hinged with locking rods, and each locking rod is fixedly connected with a quick-release buckle. Adjacent locking rods are detachably connected through quick-release buckles.

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

[0011] The head restraint straps are detachably attached to both sides of the headrest of the dental treatment table via Velcro, providing initial fixation of the child's head from both sides and limiting large-scale rotation. Subsequently, the cervical fixation component is worn around the child's neck. The shoulder supports of the cervical fixation component support the child's shoulders. When the controller controls the extension and retraction of the electric actuator output shaft, the staggered arrangement of the second U-shaped block and the first U-shaped block drives the movement of the second frame, thereby changing the distance between the upper and lower cervical fixation rings. This provides support between the child's jaw and shoulders and allows for precise adjustment based on the child's neck thickness, ensuring a close fit and preventing the child's head from swaying from side to side during surgery. When fine-tuning of the child's head orientation is required, the controller precisely controls the extension and retraction of the electric actuator output shaft, causing a change in the relative position between the upper and lower cervical fixation rings, thus achieving a subtle adjustment of the child's head angle.

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

[0013] 1. This invention effectively fixes the child's head and neck through the synergistic effect of the head restraint strap and the neck fixation component; the head restraint strap restricts the child's head from turning too much, and the neck fixation component further prevents the head from swaying from side to side, reducing the amplitude of head movement during surgery and improving the stability of the surgical procedure.

[0014] 2. The neck fixation component of the present invention can be precisely adjusted according to the thickness of the child's neck, closely fits the neck, enhances the fixation effect, improves the child's comfort during the operation, reduces the additional pain caused by improper restraint, helps alleviate the child's fear, and makes it easier for the child to cooperate with the operation.

[0015] 3. This invention precisely controls the extension and retraction of the electric push rod output shaft through a controller, enabling fine adjustments to the angle of the child's head. This provides medical staff with a more precise operating field of vision and conditions, allowing them to observe the surgical site more clearly and operate surgical instruments more accurately, thereby improving the accuracy and success rate of the surgery. It can also shorten the operation time and reduce the child's pain and fear.

[0016] Furthermore, the inner walls of both the upper and lower neck fixation rings are arc-shaped.

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

[0018] Furthermore, airbags are fixedly connected to the inner walls of both the upper and lower neck fixation rings. The lower neck fixation ring is equipped with an inflation component for inflating the airbags and a suction component for attracting the child's attention during the surgery.

[0019] Beneficial effects: After inflation, the airbag adapts to the actual shape of the child's neck, further optimizing the fit and providing a more even pressure distribution, effectively reducing local pressure. Simultaneously, the inflated airbag fits tightly against the child's neck, increasing neck fixation. The suction component can distract the child during surgery, reducing their fear of the surgical environment and resistance to the procedure, making the surgery smoother.

[0020] Furthermore, the attraction components include an L-shaped support rod and a kicking doll, with the kicking doll's right lower leg and right thigh hinged together.

[0021] One end of the L-shaped support rod is rotatably connected to the top of the lower neck fixing ring, and the other end of the L-shaped support rod is fixedly connected to the base plate. The top of the base plate is fixedly connected to the drive unit and the power box. The left lower leg of the kicking doll is fixedly connected to the top of the power box.

[0022] The top of the power box has a sliding groove. The output shaft of the drive component extends through the side wall of the power box into the power box and is coaxially fixedly connected to the first turntable. The first turntable is eccentrically fixedly connected to the first connecting rod. The first connecting rod is rotatably engaged with the first pull rod. The first pull rod passes through the sliding groove and slides with the sliding groove. The end of the first pull rod away from the first connecting rod is hinged to the bottom of the right lower leg of the kicking doll.

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

[0024] The second connecting rod is eccentrically fixed to the end away from the second turntable, and the third turntable is coaxially fixed to the side away from the second connecting rod with a rotating shaft.

[0025] Beneficial effects: When the drive unit is activated, 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 makes a circular motion, which in turn drives the right lower leg of the kicking doll to swing back and forth around the hinge point between its left and right lower legs via 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 within the rectangular ring via the second connecting rod. The movement of the slider, in turn, drives the toy soccer ball to move up and down via the second pull rod, making the toy soccer ball present a dynamic effect of moving up and down above the right lower leg of the kicking doll. This dynamic kicking scene can attract the child's attention, allowing the child's eyes to focus on the kicking doll and the toy soccer ball, thereby effectively distracting the child's attention during the surgical process, reducing their fear of the surgical environment and resistance to the treatment procedure, and making the surgical process smoother.

[0026] Furthermore, the inflation assembly includes a piston cylinder fixedly connected to one side wall of the power box, a piston slidingly fitted on the inner side wall of the piston cylinder, and a piston rod 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, a crank is eccentrically hinged on the wheel, and the end of the crank away from the wheel is hinged to the piston rod; an air inlet pipe and an air outlet pipe are connected to the piston cylinder, and a one-way valve is connected to both the air inlet pipe and the air outlet pipe, and the air outlet pipe is connected to the airbag.

[0027] Beneficial effects: The third turntable drives the shaft to rotate, which in turn drives the wheel to rotate. Since the crank is hinged to the wheel, the rotation of the wheel causes the crank to move in a circular motion, which in turn drives the piston to move in a reciprocating linear motion within the piston cylinder via the piston rod. When the piston moves downward, the one-way valve in the intake pipe opens, allowing outside air to enter the piston cylinder; when the piston moves upward, the one-way valve in the exhaust pipe opens, forcing the air in the piston cylinder into the air bladder, thus inflating the air bladder. This design, which uses the power generated by the drive components within the power box to drive the inflation assembly, eliminates the need for additional inflation equipment, simplifying the overall structure.

[0028] Furthermore, pressure sensors are fixedly connected to the side walls of the airbag, and the controller is used to receive the pressure signals from the pressure sensors and control the drive components to stop operating based on the pressure signals.

[0029] Beneficial effects: The controller receives pressure signals from the pressure sensor and controls the drive to stop operating based on the pressure signals. When the pressure reaches the preset value, the inflation component stops working, preventing the airbag from excessively compressing the child's neck.

[0030] Furthermore, massage balls are rotatably fitted 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, further relieving the child's tension.

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

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

[0034] Furthermore, both the upper and lower neck retaining rings are made of aluminum alloy.

[0035] Beneficial effects: Aluminum alloy is lightweight and high-strength, ensuring stability while reducing overall weight and minimizing extra strain on the child's neck, thus improving comfort. Furthermore, aluminum alloy has excellent corrosion resistance, ensuring that the upper and lower neck support rings are not easily damaged during long-term use, extending their lifespan.

[0036] Furthermore, the inside of the head restraints is 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 a gentle fragrance. It can regulate the child's emotions through the olfactory nerve and help them stay relaxed during the operation to a certain extent.

[0046] The following section provides a more detailed explanation of the specific implementation method:

[0047] Example 1:

[0048] As attached Figure 1 , Figure 3 and Figure 6 As shown: pediatric surgical restraints for dentistry include head restraints symmetrically and fixedly connected to both sides of the headrest of the dental treatment table, and also include a controller; each head restraint is sewn with Velcro, and adjacent head restraints are detachably connected by Velcro; the dental treatment table is equipped with a neck fixation component to prevent the child's head from swaying from side to side during surgery.

[0049] The neck fixation assembly includes a shoulder support 1, a C-shaped upper neck fixation ring 2, and a lower neck fixation ring 3. The upper neck fixation ring 2, located near the front of the child's jaw, has a shape where its width decreases from 3 cm to 1 cm within a 5 cm radius from the point where it fits against the neck. The inner walls of both the upper neck fixation ring 2 and the lower neck fixation ring 3 are arc-shaped. The top of the shoulder support 1 and the bottom of the lower neck fixation ring 3 are fixedly connected by screws. Several first U-shaped blocks 4 are integrally formed along the circumference of the top of the lower neck fixation ring 3. The inner walls of the first U-shaped blocks 4 are all hinged to first frames 5, and each first frame 5 is hinged to an electric push rod 6.

[0050] The bottom of the upper neck fixing ring 2 is integrally formed with several second U-shaped blocks 7 along its circumference. The second U-shaped blocks 7 and the first U-shaped blocks 4 are arranged alternately. The inner sidewalls of the second U-shaped blocks 7 are all hinged with second frames 8. The output shaft of the electric push rod 6 is hinged to the inner side of the adjacent second frame 8. The controller is used to control the extension and retraction of the output shaft of the electric push rod 6, thereby adjusting the distance between the upper neck fixing ring 2 and the lower neck fixing ring 3.

[0051] Both ends of the upper neck fixing ring 2 and the lower neck fixing ring 3 are hinged with locking rods 9. Each locking rod 9 is fixedly connected with a quick-release buckle 10 by screws. Adjacent locking rods 9 are detachably connected by quick-release buckles 10.

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

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

[0054] Pressure sensors are fixedly bonded to the side walls of the airbag. The controller receives the pressure signals from the pressure sensors and controls the DC geared 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 treatment table, lets the child lie flat on the table, and adjusts the lying position appropriately. They then pick up the upper cervical fixation ring 2 and the lower cervical fixation ring 3, open the quick-release buckle 10, and unfold all the locking rods 9. Next, they place the lower cervical fixation ring 3 under the child's neck, and then place the upper cervical fixation ring 2 above the child's neck, ensuring that the shoulder support 1 is placed on the child's shoulder.

[0057] During oral surgery, doctors need to perform comprehensive manipulations of the child's mouth. The upper cervical fixation ring 2 and lower cervical fixation ring 3 should avoid obstructing the surrounding oral cavity. Therefore, this invention optimizes the shape of the upper cervical fixation ring 2 and lower cervical fixation ring 3, allowing sufficient space for oral manipulation while securing the neck. This invention also designs the front ends of the upper and lower cervical fixation rings to be narrower, reducing coverage on the front of the child's lower jaw.

[0058] After adjusting the position, the medical staff connected the adjacent locking rods 9 with the quick-release buckle 10, so that the upper neck fixation ring 2 and the lower neck fixation ring 3 were fixed to the child's neck.

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

[0060] by Figure 4 For example, medical staff use a controller to control the output shaft of a DC geared motor to rotate, which in turn drives the wheel 28 to rotate. Since the crank 29 is eccentrically hinged to the wheel 28, the rotation of the wheel 28 causes the crank 29 to perform crank motion. Because the crank 29 and the piston rod 27 are hinged, the crank motion of the crank 29 drives the piston rod 27, which in turn drives the piston to perform up-and-down reciprocating motion within the piston cylinder 26.

[0061] When the piston moves downward, the one-way valve in the intake pipe opens, allowing outside air to enter the piston cylinder 26; when the piston moves upward, the one-way valve in the exhaust pipe opens, forcing the air in the piston cylinder 26 into the airbag. After inflation, the airbag adaptively adjusts to the actual shape of the child's neck, further optimizing the fit between the airbag and the child's neck, providing a more even pressure distribution, effectively reducing localized pressure on the child's neck. Simultaneously, the inflated airbag fits tightly against the child's neck, enhancing the fixation effect.

[0062] Medical staff pre-set a pressure preset value for the controller. Pressure sensors on the side wall of the airbag monitor the pressure of the airbag on the child's neck in real time and transmit the pressure signal to the controller. When the pressure reaches the preset value, the controller stops the DC motor to prevent the airbag from excessively compressing the child's neck.

[0063] by Figure 1 , Figure 3 and Figure 6For example, subsequently, based on the different lengths of the children's necks, medical staff activate the electric push rod 6 via the controller. The output shaft of the electric push rod 6 begins to extend and retract. Simultaneously, since the electric push rod 6 is hinged to the inner side of the first frame 5, which is hinged to the first U-shaped block 4, and the output shaft of the electric push rod 6 is hinged to the inner side of the second frame 8, which is hinged to 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 fixation ring 2 to move stably up and down. The distance between the upper neck fixation ring 2 and the lower neck fixation ring 3 changes accordingly. When the child's neck is long, by controlling all the output shafts of the electric push rod 6 to extend until the upper neck fixation ring 2 fits tightly against the child's lower jaw.

[0064] Meanwhile, since the curve of the line connecting the jaw and the back of the neck is different for each child, medical staff can operate the controller to control the extension and retraction distance of the output shaft of the electric push rod 6 at different positions to adapt to the curve of the line connecting the jaw and the back of the neck of different children. For example, when a child's jaw is low and the back of the neck is high, medical staff can use the controller to adjust the extension of the output shaft of the electric push rod 6 below the back of the neck and the retraction of the output shaft of the electric push rod 6 below the jaw, so that the upper neck fixation ring 3 tilts forward towards the child to further fit the jaw curve of different children. This realizes the function of providing personalized adjustment and fixation according to different children, and also improves the comfort of the child, providing stable support between the child's jaw and shoulder. When the upper neck fixation ring 2 is tightly fitted to the child's jaw, medical staff use the controller to stop the operation of all electric push rods 6. At this time, the upper neck fixation ring 2 can limit the child's neck and effectively prevent the child's head from swaying from side to side during the operation.

[0065] Throughout the surgery, medical staff can control the extension and retraction of the electric push rod 6 output shaft at different positions via the controller, according to the needs of the surgery, to make fine adjustments to the angle of the child's head, providing medical staff with a more precise operating field of vision and conditions, so that medical staff can observe the surgical site more clearly and operate surgical instruments accurately.

[0066] For example, when it is necessary to slightly tilt the child's head 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 retract slightly. At this time, the upper neck fixing ring 2 can tilt to the right, thereby causing the child's head to tilt slightly to the right. This 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 surgery, the medical staff opened the quick-release buckles 10 on the locking rods 9 of the upper cervical fixation ring 2 and the lower cervical fixation ring 3, and removed the cervical fixation components from the child's neck. They then unfastened the Velcro on the head restraints and removed them from both sides of the child's head.

[0068] Example 2:

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

[0070] The top of the base plate 13 is also fixedly connected to the second drive component 14 by screws, and the controller is used to control the rotation of the output shaft of the second drive component 14.

[0071] The top of the power box 15 has a sliding groove; the output shaft of the second drive component 14 extends through the side wall of the power box 15 into the power box 15 and is coaxially fixed to the first turntable 16 by screws. The first turntable 16 has an eccentrically integrally formed first connecting rod 17 on the side wall away from the second drive component 14. The first connecting rod 17 is rotatably engaged with the first pull rod 18. The first pull rod 18 passes through the sliding groove and slides with the sliding groove. The end of the first pull rod 18 away from the first connecting rod 17 is hinged to the bottom of the right lower leg of the kicking doll 12.

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

[0073] The second connecting rod 20 is eccentrically formed at one end away from the second turntable 19, and a third turntable 25 is integrally formed thereon. The third turntable 25 and the inner wall of the power box 15 rotate in cooperation.

[0074] A microphone is fixedly connected to the side wall of the base plate 13 by screws. The controller is used to receive the sound signal emitted by the dental instrument sent by the microphone and control the operation of the second drive unit 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 surgery, when dental instruments emit sound, if the controller receives the sound of the surgical instruments from the microphone for more than 3 seconds, the controller sends a control signal to activate the second drive unit 14. In this embodiment, the second drive unit 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 circular motion. Due to the rotational cooperation between the first pull rod 18 and the first connecting rod 17, the first pull rod 18 can perform crank motion, thereby driving the right lower leg of the kicking doll 12 to swing up and down around the hinge point between it and the right thigh, simulating the action of juggling a 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... With the eccentric fixing of turntable 19, the rotation of the second turntable 19 can drive the second connecting rod 20, which in turn drives the rectangular ring 22 to slide left and right and move up and down within 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, which can only slide vertically, the second pull rod 23 can drive the toy soccer ball 24 to move up and down above the right lower leg of the kicking doll 12. With the cooperation of the toy soccer ball 24 and the right lower leg of the kicking doll 12 swinging up and down, the kicking doll 12 can simulate the scene of juggling a ball, thereby attracting the child's attention and focusing the child's eyes on the kicking doll 12 and the toy soccer ball 24. This effectively distracts the child's attention during the operation, reduces their fear of the surgical environment and resistance to the treatment operation, and makes the operation smoother.

[0077] Because dental surgery is time-consuming and usually performed while the child is awake, and because there are many dental instruments, the sound and appearance of these instruments are the main sources of anxiety and fear for children undergoing dental surgery. Therefore, the design of this suction component can shift the child's attention from the dental instruments used by the dentist to the suction component during the surgery, thereby alleviating the child's tension and allowing the child to undergo surgical treatment in a relatively relaxed and pleasant atmosphere.

[0078] Furthermore, the continuous suction effect can reduce the child's physical movements caused by fear, ensuring the safety and accuracy of the surgical procedure, avoiding interference with the surgical process due to the child's sudden movements, reducing surgical risks, increasing the success rate of the surgery, and also reducing the workload of medical staff to a certain extent, thus improving the efficiency of the entire surgical procedure.

[0079] The suction component of this invention, activated by the sound of surgical instruments in dental surgery, reduces the main sources of anxiety and fear in children undergoing dental surgery. Compared with traditional attention-grabbing devices in pediatric examinations, it reduces the risk of children losing interest due to overly monotonous devices, causing them to shift their attention back to the surgical instruments, thus falling back into tension and fear. This can lead to restlessness or non-cooperation during surgery, forcing the interruption of the procedure or prolonging the operation.

[0080] Because one end of the L-shaped support rod 11 and the top of the lower neck fixation ring 3 rotate together, 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 obscuring the child's face and thus affecting the doctor's operation.

[0081] Example 3:

[0082] As attached Figure 1 As shown, the difference from Embodiment 2 is that massage balls are rotatably fitted on the side wall of the electric push rod 6.

[0083] The specific implementation process is as follows:

[0084] As the output shaft of the electric push rod 6 extends and retracts, causing the upper neck fixing ring 2 to rise and fall, the relative position of the electric push rod 6, the upper neck fixing ring 2, and the lower neck fixing ring 3 are all hinged, causing the massage ball on the side wall of the electric push rod 6 to come into contact with the child's neck skin. At this time, the massage ball can gently massage both sides of the child's neck, further relieving the child's tension.

[0085] Example 4:

[0086] As attached Figure 1 As shown, the difference from Embodiment 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, reducing the discomfort caused by the child lying down for a long time.

[0089] Example 5:

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

[0091] The specific implementation process is as follows:

[0092] Aluminum alloy is lightweight and high-strength, ensuring stability while reducing overall weight and minimizing extra strain on the child's neck, thus improving comfort. Furthermore, aluminum alloy has excellent corrosion resistance, ensuring that the upper and lower neck fixation rings 2 and 3 are not easily damaged during long-term use, extending their service life.

[0093] Example 6:

[0094] The difference from Example 5 is that the inside 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 a gentle fragrance and regulate the child's emotions through the olfactory nerve, helping them to stay relaxed during the surgery to some extent.

[0097] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
