Description

A lighting structure for children's oral cavity observation and detection based on double alveolar support

Technical Field

The invention relates to the technical field of medical devices, and in particular to a lighting structure for observing and detecting children's oral cavity based on double alveolar support.

Background technique

Childhood is a critical period for physical growth and development. Oral health is closely related to overall health. Oral diseases not only cause pain and discomfort to children, but may also cause systemic diseases. Oral diseases can affect children's diet and sleep, which in turn affects their physical growth and development.

When conducting relevant examinations on children's oral cavity, medical staff usually need to use appropriate instruments to support the child's mouth so that the child can keep his mouth open during the examination, making it easier for medical staff to use a searchlight to observe, analyze and treat the internal condition of the child's mouth.

However, nowadays, when supporting children's mouths, support forceps are generally used. This method can easily cause children to have strong resistance. In this regard, some instruments use biting to achieve support, but in order to ensure the support effect, these instruments usually have strong support rigidity. Therefore, after the examination, due to the fragile oral structure of children, it is inevitable that children will feel uncomfortable. During the examination, if the instruments are removed to relieve the children, it will increase the burden on medical staff.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

Referring to FIGS. 1 to 8 , in an embodiment of the present invention, a double alveolar support-based child oral cavity observation and detection lighting structure includes a support base 1 and a vertical plate 2 and a vertical plate 22 fixedly mounted on the support base 1, and further includes:

Two connecting plates 3 are slidably provided on the vertical plate 2, and the two connecting plates 3 are respectively connected to two arc-shaped members 10 located on one side of the vertical plate 2 through a set of expansion control mechanisms. A gap is reserved between the two arc-shaped members 10, and a fill light 33 is movably provided in the gap;

A threaded drive mechanism is mounted on the support seat 1 and cooperates with a power supply mechanism provided on the vertical plate 22. The threaded drive mechanism is also connected to an intermittent trigger mechanism installed on the support seat 1. The intermittent trigger mechanism is intermittently triggered during the movement of the threaded drive mechanism.

Whenever the intermittent trigger mechanism moves, it can drive the two connecting plates 3 to slide back and forth on the vertical plate 2, so that the two arc-shaped members 10 perform an opening and closing action. At the same time, the power supply mechanism is triggered to disconnect the power-on state of the fill light 33.

It should be noted that, in actual work, the upper lip and upper teeth of the child are placed on one of the arc-shaped members 10 (the upper arc-shaped member 10), and the lower lip and lower teeth are placed on the other arc-shaped member 10 (the lower arc-shaped member 10). In order to prevent the child's teeth from being accidentally damaged during the inspection, a groove 1001 (i.e., the part where the teeth are placed) is provided on the arc-shaped member 10, and a sponge pad 11 is provided in the groove 1001 to provide protection for the child's teeth.

Secondly, a cross arm 34 is fixedly installed on the vertical plate 2, and a positioning tube 35 is provided at one end of the cross arm 34 away from the vertical plate 2. The positioning tube 35 is ball-jointed with the cross arm 34, and an insertion rod 36 is slidably provided in the positioning tube 35. One end of the insertion rod 36 is electrically connected to the fill light 33, and the other end is connected to the power supply mechanism. During actual operation, medical staff can hold the insertion rod 36 to achieve position control of the fill light 33 within a certain range. Preferably, a camera can be arranged at one end of the insertion rod 36 close to the fill light 33 to record the situation in the child's mouth.

During the specific operation, the medical staff drives the two arc-shaped members 10 to move away from each other through the two groups of the expansion control mechanisms until the child's mouth is stretched to an angle suitable for the inspection work, and then starts the threaded drive mechanism. The threaded drive mechanism will intermittently drive the intermittent trigger mechanism to move during the movement. Whenever the intermittent trigger mechanism moves, it will drive the two connecting plates 3 to slide closer to or away from each other. Correspondingly, the two arc-shaped members 10 will perform reciprocating opening and closing actions, which has a relaxing effect on the child's oral muscles, avoiding subsequent discomfort caused by the child's oral muscles being stretched too long during the inspection process, and can also relieve the child's tension to a certain extent. While the two arc-shaped members 10 are performing the reciprocating opening and closing actions, the power supply mechanism cooperates with the threaded drive mechanism, and the power supply mechanism disconnects the passband state of the fill light 33. On the one hand, it can prompt the medical staff to terminate the observation operation, and on the other hand, it provides relief time for the eyes of the medical staff to avoid strong light causing fatigue to the medical staff's vision, which is conducive to the subsequent observation operation.

It should be pointed out that in actual use, in order to prevent the child's mouth from being separated from the arc-shaped parts 10 during the reciprocating opening and closing of the two arc-shaped parts 10, this structure can be used in conjunction with a special examination seat, that is, the seat is used to limit the child's head.

Please refer to Figures 6 and 7 again. The expansion control mechanism includes a first screw rod 13 rotatably mounted on the connecting plate 3 and an assembly plate 4 slidably arranged on the vertical plate 2. The assembly plate 4 is fixedly connected to the arc plate 5. The arc member 10 is connected to the arc plate 5 through two groups of elastic components. A protruding block 12 is also fixed to the side of the assembly plate 4. The first screw rod 13 penetrates the protruding block 12 and is threadedly connected to the protruding block 12.

When in use, after the child's upper lip, upper teeth and lower lip, lower teeth correspond to the two arc-shaped parts 10 respectively, the medical staff can rotate the first screw rod 13, so that the first screw rod 13 will be threadedly engaged with the protruding block 12, and then the two assembly plates 4 will move away from each other, prompting the two arc-shaped parts 10 to open the child's mouth.

The elastic component includes a guide cylinder 6 fixedly mounted on the arc plate 5, a telescopic rod 7 slidably fitted with the guide cylinder 6, and a first cylindrical spring 9 arranged inside the guide cylinder 6, one end of the telescopic rod 7 is fixed to the arc member 10, and the other end is fixed to a boss 8 slidably arranged in the guide cylinder 6, the first cylindrical spring 9 is sleeved on the outer periphery of the telescopic rod 7, and the two ends are respectively connected to the boss 8 and the inner wall of the guide cylinder 6.

During the operation, the setting of the elastic component can make the arc-shaped member 10 and the arc-shaped plate 5 not rigidly connected. Therefore, when the child bites the two arc-shaped members 10 with force, the telescopic rod 7 can slide a short distance to the outside of the guide cylinder 6, and the first cylindrical spring 9 is compressed. Therefore, during the inspection process, a certain amount of activity space is provided for the child's oral cavity, thereby further providing protection for the child's oral cavity.

Please refer to Figures 3 and 5 again. The threaded drive mechanism includes a second screw rod 24 rotatably mounted on the support base 1, a threaded sleeve 25 sleeved on the second screw rod 24 and threadedly connected to the second screw rod 24, and a drive motor 23 mounted on the vertical plate 22. One end of the second screw rod 24 away from the support base 1 is connected to the output end of the drive motor 23, and the threaded sleeve 25 is connected to the intermittent trigger mechanism.

It should be emphasized that the driving motor 23 should use a servo motor with a bidirectional drive at the output end, so that when it drives the second screw rod 24 to rotate, the threaded sleeve 25 will be threadedly matched with the second screw rod 24, so that the threaded sleeve 25 will move along the second screw rod 24, thereby causing the intermittent trigger mechanism to move intermittently, causing the two arc-shaped members 10 to perform reciprocating opening and closing actions, ensuring that the entire examination process is divided into multiple stages to relieve the emotions of children and the fatigue of medical staff.

Please refer to Figures 7 and 8 again, the intermittent trigger mechanism includes a rolling fit assembly mounted on the support seat 1 and a reciprocating push-pull assembly connected to the rolling fit assembly, the rolling fit assembly includes a vertical shaft 21 rotatably mounted on the support seat 1 and a sleeve 26 slidably sleeved on the vertical shaft 21 and fixed to the threaded sleeve 25;

Among them, one end of the vertical shaft 21 away from the support seat 1 is connected to the reciprocating push-pull assembly, and a plurality of connected slide grooves are provided on the vertical shaft 21. A ball (not shown in the figure) that rolls and engages with the slide groove is provided on the inner wall of the sleeve 26, and the slide groove includes a connected vertical section 2101 and a spiral section 2102.

When the threaded sleeve 25 is threadedly engaged with the second screw rod 24 and moves on the second screw rod 24, the threaded sleeve 25 drives the sleeve 26 to move together on the vertical shaft 21. When the ball on the inner wall of the vertical shaft 21 passes through the vertical section 2101 (parallel to the central axis of the vertical shaft 21), the vertical shaft 21 does not rotate, and the two arc-shaped members 10 keep the child's cavity in an open state. When the ball passes through the spiral section 2102, it will roll with the vertical shaft 21, thereby causing the vertical shaft 21 to rotate. The end of the vertical shaft 21 away from the support seat 1 drives the reciprocating push-pull assembly, and the reciprocating push-pull assembly drives the two connecting plates 3 to slide back and forth on the vertical plate 2, and the two arc-shaped members 10 perform a reciprocating opening and closing action to relax the child's oral muscles.

The reciprocating push-pull assembly includes a disk 18 rotatably mounted on the side of the vertical plate 2 and a driving plate 16 connected to the disk 18 via a push-pull rod 19, one end of the push-pull rod 19 is rotatably connected to the driving plate 16, and the other end is rotatably connected to the eccentric part of the disk 18, and the rotating shaft of the disk 18 is connected to the vertical shaft 21 via a bevel gear set 20. A column 17 is fixed to each end of the driving plate 16, and a transmission plate 14 is fixed to the side of the link plate 3 facing the driving plate 16, and an inclined groove 15 is provided on the transmission plate 14, and the column 17 passes through the inclined groove 15 and is slidably connected to the transmission plate 14.

In detail, the bevel gear set 20 includes a first bevel gear fixedly mounted on the end of the vertical shaft 21 away from the support seat 1 and a second bevel gear fixedly mounted coaxially with the disc 18, and the second bevel gear meshes with the first bevel gear.

Whenever the threaded sleeve 25 drives the sleeve 26 to move, so that the ball on the inner wall of the sleeve 26 passes through the spiral segment 2102, the vertical shaft 21 will rotate an integer multiple of circles (the number of thread circles of the spiral segment 2102 is an integer, and the multiple vertical segments 2101 on the vertical shaft 21 are collinear). When the vertical shaft 21 rotates, the bevel gear set 20 will drive the disc 18 to rotate an integer multiple of circles. Correspondingly, the disc 18 drives the drive plate 16 to reciprocate through the push-pull rod 19, and the column 17 slides with the transmission plate 14 through the inclined groove 15, so that the connecting plate 3 slides back and forth on the vertical plate 2, and the two arc-shaped members 10 perform reciprocating opening and closing actions.

Please refer to Figures 5 and 8 again. The power supply mechanism includes a static contact 32 fixedly mounted on the vertical plate 22 and electrically connected to the fill light 33, and a moving contact 31 movably mounted on the vertical plate 22 and adapted to the static contact 32. The moving contact 31 is connected to a driven component mounted on the vertical plate 22. When the moving contact 31 is connected to the static contact 32, the fill light 33 is in a powered state. The driven component includes two cross bars 28 slidably mounted on the vertical plate 22, a driven plate 30 fixedly connected to the two cross bars 28, and a second cylindrical spring 29 respectively sleeved on the outer circumference of the two cross bars 28. The two ends of the second cylindrical spring 29 are respectively connected to the vertical plate 22 and the driven plate 30. The driven plate 30 abuts against a pulley 27 mounted on the threaded sleeve 25.

The moving contact 31 is fixed to the driven plate 30 , and a plurality of recessed portions 3001 are provided on the driven plate 30 . The number of the recessed portions 3001 is equal to the number of the spiral segments 2102 , and inclined surfaces are formed on both sides of the recessed portions 3001 .

When the threaded sleeve 25 drives the pulley 27 to roll along the non-recessed part on the driven plate 30, the second cylindrical spring 29 is in a compressed state, an electrical connection is established between the moving contact 31 and the static contact 32, the fill light 33 is in a powered-on state, and when the ball on the inner wall of the vertical shaft 21 passes through the spiral section 2102, the pulley 27 just passes through the inclined surface and rolls into the recessed portion 3001, so that the second cylindrical spring 29 rebounds, causing the driven plate 30 to move away from the vertical plate 22, and the driven plate 30 drives the moving contact 31 to separate from the static contact 32, so that the powered-on state of the fill light 33 is terminated, prompting medical staff to suspend inspection work and relieve their visual fatigue.

It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
