Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to an oral opening device for children that can be sterilized at high temperature. Background Art

[0002] Healthy teeth play a vital role in children's chewing, pronunciation, facial development, and mental health, but children, especially young children, often cannot cooperate with oral treatment. For children who cannot cooperate or are very afraid, it is very important to use an open mouth to help open the mouth so that they can complete oral treatment comfortably and painlessly. An open mouth, also known as a mouth opener, is an instrument used to open the mouth when breathing is difficult or unconsciousness requires gastric lavage. In medicine, based on its ability to keep the mouth open, an open mouth can also be used on uncooperative individuals, such as young babies or animals, so that drugs can be delivered to them through the esophagus or oral treatment operations can be performed. At present, the open mouth commonly used in the field of pediatric oral medicine in my country is mostly fixed outside the mouth by doctors. The open mouth is placed on the posterior molars on one side of the child to open the mouth, and then the other side of the child's mouth can be treated.

[0003] After searching, a Chinese patent with the announcement number CN 209884099 U proposes a special mouth opener for children in the dental department, including a first driving rod, a connecting mechanism, a second driving rod, a first connecting rod, a limiting mechanism, an adjusting mechanism and an opening mechanism, wherein the second driving rod is fixedly connected to the connecting mechanism; the first connecting rod is fixedly connected to the connecting mechanism; the limiting mechanism is arranged between the first driving rod and the second driving rod; the adjusting mechanism is fixedly connected to the connecting mechanism, and the adjusting mechanism includes a slide bar, a limiting tooth, a slide plate, a fixing tooth, a handle, a second connecting rod and a second spring; the opening mechanism is fixedly connected to the first connecting rod and the second connecting rod. The special mouth opener for children in the dental department provided by the utility model has a wide range of applications, can quickly adjust the vertical distance between the two clamping plates, has high comfort and is conducive to treatment.

[0004] Existing mouth openers are usually made of metal, which is relatively hard and can easily damage the face of a child.

In addition, due to the presence of saliva in the child's mouth, the mouth opener is likely to slip off, causing damage to the child's mouth when the mouth opener slips off, and there is even a risk of accidental swallowing. Since the child cannot operate the mouth opener by himself, a nurse is required to assist in holding the mouth opener. In the prior art, the operating end of the mouth opener is usually set directly in front of the child. The nurse will block the doctor when operating, and the operating table becomes crowded, which is not conducive to the operation. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0029] The inventors have found that existing mouth openers are usually made of metal, which is relatively hard and can easily damage the face of a child. The area bitten by the child is also likely to damage the adjacent oral mucosal soft tissue and teeth. In addition, due to the presence of saliva in the child's mouth, the mouth opener is likely to slip off, causing damage to the child's mouth when it slips, and there is even a risk of accidental swallowing. Since the child cannot operate the mouth opener by themselves, a nurse is required to assist in holding the mouth opener. In the prior art, the operating end of the mouth opener is usually set directly in front of the child. The nurse will block the doctor when operating, and the operating table will become crowded, which is not conducive to the operation.

[0030] Based on the above findings, the present application proposes an opener for children's oral cavity that can be sterilized at high temperature. A protective cover made of soft material is designed on the outside of the opening mechanism to prevent the teeth of young children from being damaged. An arc-shaped limit plate is provided on the inner side of the tooth receiving groove to prevent the opener from slipping. The arc-shaped limit plate is made of rubber material, and a sponge sheet is also provided on the surface in contact with the gums of the young child. The wet sponge sheet is in contact with the oral wall to avoid damage to the soft tissue of the oral mucosa. The operating end of the opener is provided on the side to prevent the medical staff operating the opener from blocking the doctor's line of sight and affecting the surgical operation. Embodiment 1

[0031] See also Figure 1-Figure 5 The present application discloses an opener for children's oral cavity that can be sterilized at high temperature, including an opening mechanism 1. The opening mechanism 1 is symmetrically arranged in two groups. The opening mechanism 1 is used to cover the upper and lower unilateral teeth of the child and the gums near the teeth, so that the stability of the opener is improved and it is prevented from slipping. The opening mechanism 1 includes a retainer body 101. The retainer body 101 is a fan-shaped structure, and the curvature of the retainer body 101 is consistent with the curvature of the unilateral gums of the child. The retainer body 101 is made of stainless steel, which is easy to clean and disinfect. A longitudinal tooth accommodating groove 102 is opened on the inner side of the retainer body 101, and the curvature of the tooth accommodating groove 102 is consistent with the curvature of the unilateral gums of the child.

[0032] The opening mechanism 1 is also provided with an arc-shaped limiting groove 103 on the inner side, and interconnected longitudinal grooves are provided on both sides of the arc-shaped limiting groove 103. An arc-shaped limiting piece 104 is provided in the arc-shaped limiting groove 103, and connecting pieces 105 are fixedly connected on both sides of the arc-shaped limiting piece 104. The shape and size of the connecting piece 105 are adapted to the longitudinal groove. By providing the longitudinal groove and the connecting piece 105, the arc-shaped limiting piece 104 can be prevented from slipping during use. The arc-shaped limiting piece 104 is made of a material that can be deformed and can maintain a basic shape, such as a rubber material, so that it can be squeezed and dislocated with each other when placed, and the connecting pieces 105 on both sides are placed in the longitudinal groove.

[0033] In order to prevent children's teeth from being damaged, a protective cover 106 is provided on the opening mechanism 1. The protective cover 106 is made of silicone material. The outer surface of the protective cover 106 is designed in an arc shape to prevent the edges and corners from causing discomfort to children. The opening 1 of the protective cover 106 is provided on the outer side of the opening mechanism 1. When the protective cover 106 is installed, the opening mechanism 1 is inserted from the opening 1. The protective cover 106 is provided with an opening 2 of the same shape and size as the arc-shaped limiting groove 103, which is convenient for inserting the arc-shaped limiting piece 104. The protective cover 106 is designed as an open structure, which is convenient for disassembly, cleaning and disinfection.

[0034] When in use, the child's teeth and part of the gums are placed in the tooth receiving groove 102. Since a protective cover 106 is provided, the child only contacts the soft protective cover 106 but not the internal retainer body 101, thereby preventing the hard metal material from damaging the child's teeth and gums. The arc-shaped limiting piece 104 contacts the inner gums and can play a certain limiting role to prevent the opening mechanism 1 from slipping. Embodiment 2

[0035] See also Figure 1 and Figure 6 , an actuator 2 is arranged outside the opening mechanism 1, and the actuator 2 has two groups, which are respectively connected to the two retainer bodies 101. The actuator 2 includes cross-arranged adjustment rods 201, and the two adjustment rods 201 are connected by a connecting shaft. The adjustment rod 201 includes an integrally formed connection end 202 and an operating end 203, the other side of the connection end 202 is fixedly connected to the retainer body 101, and the operating end 203 is fixedly connected with a handle 205 for medical staff to grasp, and the connection end 202 and the operating end 203 are in an "L" shape, and the two groups of operating ends 203 are bent to the same side, and a spring 204 is fixedly connected between the two groups of operating ends 203.

[0036] A spring 204 is fixedly connected between the two operating ends 203, so that the two operating ends 203 are naturally opened due to the tension of the spring 204. Since the operating end 203 and the connecting end 202 are integrally formed and cross-connected by the connecting axis, when the operating end 203 is opened, the two retainer bodies 101 are naturally opened. In the initial state, there is a certain height difference between the two. When a larger angle is needed to be opened, the medical staff operates the two handles 205 to further increase the distance between them, thereby increasing the distance between the two retainer bodies 101. In addition, since the operating end 203 is located on the side, on the same side as the tooth side that is opened, it can avoid the medical staff operating the mouth opener blocking the doctor's line of sight and affecting the surgical operation.

[0037] For ease of operation, "L" and "R" marks are respectively provided on the two handles 205. When the handle 205 marked with "L" is located at the top, it corresponds to the medical staff placing the mouth opener on the left teeth of the child, and the doctor performs an examination or surgical operation on the right side of the child's mouth; when the handle 205 marked with "R" is located at the top, it corresponds to the medical staff placing the mouth opener on the right teeth of the child, and the doctor performs an examination or surgical operation on the left side of the child's mouth. Embodiment 3

[0038] In addition, in order to avoid damaging the oral mucosal soft tissue of children, a sponge sheet can be provided on the arc-shaped limiting sheet 104, and a plurality of arc-shaped protrusions can be provided on the arc-shaped limiting sheet 104. The sponge sheet is embedded on the outer surface of the arc-shaped limiting sheet 104, and the arc-shaped protrusions press the sponge sheet against the inner surface of the arc-shaped limiting groove 103. When in use, the sponge sheet can be soaked to make it fit more closely with the arc-shaped limiting sheet 104 and not easy to fall off. At the same time, the sponge sheet is also made softer, so that the gums and surrounding soft tissues of children in contact with it have a good touch, avoiding discomfort and damage.

[0039] The use process of this utility model is:

[0040] 1. First, determine the use position of the mouth opener according to the doctor's operating position, and adjust the use direction of the mouth opener. When the handle 205 marked with "L" is located at the top, it corresponds to the medical staff placing the mouth opener on the left teeth of the child, and the doctor performs an examination or surgical operation on the right side of the child's mouth; when the handle 205 marked with "R" is located at the top, it corresponds to the medical staff placing the mouth opener on the right teeth of the child, and the doctor performs an examination or surgical operation on the left side of the child's mouth.

[0041] 2. Put the mouth opener into the corresponding position of the child's mouth, and place the child's teeth and part of the gums in the tooth receiving groove 102. Since the sleeve is provided with a protective sleeve 106, it only contacts the soft protective sleeve 106 but not the internal retainer body 101, thereby preventing the hard metal material from damaging the child's teeth and gums; the arc-shaped limiting piece 104 contacts the inner gums and can play a certain limiting role to prevent the opening mechanism 1 from slipping; the sponge sheet is arranged on the outer surface of the arc-shaped limiting piece 104, so that the gums and surrounding soft tissues of the child in contact with it have a good touch, avoiding discomfort and damage.

[0042] 3. In the initial state, the two retainer bodies 101 are naturally opened. When a larger opening angle is required, the medical staff operates the two handles 205 to further increase the distance between them, thereby increasing the distance between the two retainer bodies 101.

[0043] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
