Description

Technical Field

[0001] This application relates to the field of dental medical devices, and more particularly to a tongue depressor for dental care in medical dentistry. Background Technology

[0002] The Department of Stomatology is a medical specialty that focuses on oral health and disease treatment. Among the treatments, tooth grinding and cutting is one of the most common methods. By using a high-speed turbine handpiece and selecting appropriate and sharp grinding and cutting burs, various cutting and adjustment operations are performed on the patient's teeth to achieve satisfactory treatment results and maintain oral health.

[0003] The relevant technology mainly uses a tongue depressor to assist in treatment. It includes a mouth opener set on the left and right sides and a tongue depressor between the mouth openers. This helps the patient open their mouth while the tongue does not touch the tooth grinding and cutting bur, thus avoiding damage to the tongue or floor of mouth mucosa.

[0004] However, in the existing technology, the position and extension distance of the tongue depressor of the open tongue depressor are fixed, and the position of the tongue depressor cannot be adjusted so that the tongue depressor presses accurately on the tongue. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a tongue depressor for dental care in the field of dentistry, and to provide a clinical tongue depressor for dentistry that can overcome or at least partially solve the above problems.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: A tongue depressor for dental care in medical dentistry includes a mouth opener body. The mouth opener body includes a fixed base and at least two biting forceps. The fixed base includes a first through hole, and several fixing grooves are formed on the inner wall of the first through hole. The two biting forceps are disposed opposite to each other on the upper and lower sides of the fixed base, and both are rotatably connected to the outer wall of the fixed base so that the two biting forceps move closer or further away from each other. The movable pressure rod includes a tongue depressor part and a fixed rod. The outer surface of the fixed rod away from the tongue depressor part is provided with a fastening part that matches the fixing groove. The tongue depressor part is connected to the fixed rod. The fixed rod is slidably disposed in the first through hole, and the fastening part extends into the fixing groove.

[0007] Optionally, it also includes a limiting structure located within the first through hole, the limiting structure being disposed between the movable pressure rod and the inner wall of the first through hole;

[0008] The limiting structure includes a guide post, an elastic element, a pressure plate, and a guide cylinder; the guide post is disposed on the opposite side of the fixed groove, the guide cylinder is disposed on the pressure plate, the guide cylinder is sleeved on the guide post, and the elastic element is sleeved on the guide cylinder and is in a compressed state so that the pressure plate contacts the movable pressure rod.

[0009] Optionally, the pressure plate is provided with a guide groove, the groove direction of which is parallel to the opening direction of the first through hole.

[0010] Optionally, the fixing rod includes a mounting sleeve and a mounting rod, the mounting sleeve includes a hollow mounting channel, the pressure tongue is connected to the mounting rod, and the mounting rod is detachably fixed in the mounting channel.

[0011] Optionally, the bite forceps includes a bite portion and a handle connected together, the bite portion including a bite groove that conforms to the contour of the teeth.

[0012] Optionally, the biting part is provided with a second through hole for the saliva tube to pass through, and the inner wall of the second through hole is covered with an anti-slip layer.

[0013] Optionally, an anti-slip sleeve may also be included, which covers the outer surface of the tongue depressor.

[0014] Optionally, the tongue depressor is flat and horizontally positioned.

[0015] Optionally, the handle includes a first segment and a second segment connected to each other, the first segment being connected to the biting part, and the two first segments being arranged in parallel.

[0016] Optionally, a second elastic element in a compressed state is provided between the two handles.

[0017] Compared with the prior art, the embodiments of this application use rotatable biting forceps arranged opposite each other, with the biting parts respectively fitting against the upper and lower teeth to open the patient's mouth and achieve the function of opening the mouth. At the same time, by setting several fixing slots in the fixing base, the movable depressor is fixed in different fixing slots through the buckling part set on the fixing rod, thereby changing the length of the movable depressor outside the fixing slot, thereby changing the position of the tongue depressor in the oral cavity. This allows the tongue depressor to match the actual oral structure of different people and improves the stability of the tongue depressor. Attached Figure Description

[0027] Mouth openers are primarily used when a patient's oral cavity is unable to open itself due to illness, injury, or impaired consciousness. Their unique shape and function allow for direct intervention, ensuring the smooth progress of treatment procedures. Mouth openers can be divided into two types: top-and-bottom opening and left-and-right opening. The appropriate type should be selected based on the needs. Generally, mouth openers need to be used in conjunction with a tongue depressor to prevent the patient's tongue from flipping up and coming into contact with sharp oral medical instruments. For left-and-right mouth openers, when the mouth is opened, the tongue depressor in the middle can press the tongue down to the bottom of the mouth. However, for top-and-bottom mouth openers, because the tongue depressor is still some distance from the bottom of the mouth, the angle of the mouth opener needs to be adjusted so that it enters the patient's mouth at an angle from above, allowing the tilted tongue depressor to contact the tongue. However, due to the tilted setting, there is still some distance between the tongue depressor and the tongue, making it impossible to accurately press the tongue down.

[0028] Example 1

[0029] Based on this, see Figure 1 , Figure 1 A tongue depressor for dental care in a medical dentistry is proposed, comprising a mouth opener body and biting forceps 10. The mouth opener body includes a pair of biting forceps 10 and a fixing base 11. The fixing base 11 includes a first through hole 111, and several fixing grooves 112 are formed on the inner wall of the first through hole 111. The two biting forceps 10 are arranged vertically opposite each other and are rotatably fixed to the outer wall of the fixing base 11, so that the two biting forceps 10 can move closer or further apart. The movable pressure rod includes a tongue depressor part 20 and a fixing rod 21. The outer surface of the fixing rod 21 away from the tongue depressor part 20 is provided with a fastening part 22 that matches the fixing groove 112. The tongue depressor part 20 is connected to the fixing rod 21. The fixing rod 21 is slidably disposed in the first through hole 111, and the fastening part 22 extends into the fixing groove 112. Figure 2 As shown, during use, the patient is positioned on the side away from the fixation seat 11, the bite forceps 10 is brought close to the patient and inserted into the patient's mouth, the bite forceps 10 is opened so that the bite forceps 10 opens from the upper and lower openings, the fixing slots 112 are arranged linearly, and the fastening part 22 of the fixing rod 21 is inserted into different fixing slots 112 through interference fit, so as to adjust the extension distance of the movable pressure rod.

[0030] In this embodiment, the fixing base 11 is cylindrical, and the inner wall of the first through hole 111 in the middle includes an upper surface and a lower surface that are parallel to each other. The fixing groove 112 is disposed on the upper surface or the lower surface so that the fastening part 22 can be aligned with the fixing groove 112. The cross-sectional profile of the first through hole 111 can be rectangular or trapezoidal. The end of the fixing rod 21 can be received in the first through hole 111 or can pass through the first through hole 111 so that the user can more conveniently adjust the extension distance of the movable pressure rod. This application does not limit this.

[0031] In one embodiment, a limiting structure 30 is further included within the first through hole 111. The limiting structure 30 is disposed between the movable pressure rod and the inner wall of the first through hole 111. Specifically, the limiting structure 30 includes a guide post 31, a first elastic element 32, a pressure plate 33, and a guide cylinder 34. The guide post 31 is disposed on the opposite side of the fixing groove 112, and the guide cylinder 34 is disposed on the pressure plate 33. The guide cylinder 34 is sleeved on the guide post 31, and the first elastic element 32 is sleeved on the guide cylinder 34 and is in a compressed state, so that the pressure plate 33 contacts the movable pressure rod. Under the action of the first elastic element 32, the limiting structure 30 presses the pressure plate 33 towards the side closer to the fixing groove 112. A certain elasticity allows the movable pressure rod to be inserted between the limiting structure 30 and the fixing groove 112, so that the pressure plate 33 presses down on the movable pressure rod, thereby making the fastening part 22 more stably connected to the fixing groove 112 and increasing the stability of the movable pressure rod.

[0032] In this embodiment, the first elastic element 32 is configured as a spring, which is sleeved on the outside of the guide cylinder 34 and the guide post 31 and is in a compressed state to lift the pressure plate 33. The sum of the lengths of the guide post 31 and the guide cylinder 34 is greater than or equal to the distance between the two opposite inner walls of the first through hole 111, so that when the movable pressure rod is pulled out, the pressure plate 33 will not fall out of the first through hole 111.

[0033] In one embodiment, such as Figure 3 As shown, the pressure plate 33 is provided with a guide groove 331, and the groove direction of the guide groove 331 is parallel to the opening direction of the first through hole 111. Through the guide groove 331, when adjusting the position of the movable pressure rod, the movement of the movable pressure rod in a single direction can be restricted, making it convenient for the user to quickly adjust the extension distance of the movable pressure rod.

[0034] In this embodiment, the shape of the guide groove 331 matches part of the outer contour of the movable pressure rod, and the bottom surface of the guide groove 331 can be arc-shaped or geometric.

[0035] In one embodiment, the bite forceps 10 includes a bite portion 101 and a handle 102 connected together. The bite portion 101 includes a bite groove that conforms to the contour of the teeth. Specifically, the bite groove is arc-shaped so that it matches the tooth arrangement. The bite portion 101 can improve the stability when opening the mouth and prevent the teeth from slipping off the bite portion 101.

[0036] The handle 102 includes a first segment and a second segment connected to each other. The first segment is connected to the engagement part 101, and the two first segments are arranged in parallel. An angle is formed between the first segment and the second segment, and the angle is hinged to the outer wall of the fixed cylinder.

[0037] Specifically, when the handle 102 is pushed outward by the first elastic element 32, the two first sections are parallel. When the second section is pressed by lever principle, the handle 102 rotates around the hinge point, thereby moving the two first sections away from each other and opening the patient's mouth.

[0038] Furthermore, a second elastic element 104 in a compressed state is provided between the two handles 102. The second elastic element 104 is configured as a spring or an elastic sheet. The second elastic sheet is in a compressed state to apply an outward force to the handles 102 and prevent the handles 102 from rotating freely.

[0039] In one embodiment, the occlusal portion 101 is provided with a second through hole 103 for the passage of a saliva suction tube, and the inner wall of the second through hole 103 is covered with an anti-slip layer. This facilitates the insertion of the suction tube and prevents saliva from affecting the operation during patient treatment.

[0040] In one embodiment, an anti-slip sleeve is also included, which covers the outer surface of the tongue depressor 20. The anti-slip sleeve serves two purposes: firstly, it prevents slipping; secondly, it is disposable and can be replaced after each use to avoid cross-infection.

[0041] In one embodiment, the tongue depressor 20 is flat and horizontally positioned. The flat tongue depressor 20 is smaller in size, allowing for smoother entry into the patient's mouth while also providing space for the treatment instrument. In this embodiment, the edges of the flat tongue depressor 20 are all rounded to avoid scratching the patient's mouth.

[0042] Example 2

[0043] like Figure 4 As shown, Figure 4This paper presents another schematic diagram of a tongue depressor for dental care in the medical field. The difference between this embodiment and Embodiment 1 is that the fixing rod 21 is a detachable structure. Specifically, the fixing rod 21 in this embodiment includes an installation sleeve 211 and an installation rod 212. The installation sleeve 211 includes a hollow installation channel. The tongue depressor 20 is connected to the installation rod 212, and the installation rod 212 is detachably fixed in the installation channel. By providing a detachable installation rod 212, a new installation rod 212 and tongue depressor 20 can be replaced after each use, avoiding cross-infection among patients. The independently designed installation rod 212 can also be manufactured using a disposable material, reducing production costs.

[0044] In this embodiment, the outer diameter of the mounting sleeve 211 is larger than the outer diameter of the mounting rod 212, and the inner diameter of the mounting channel is the same as that of the mounting rod 212. The mounting methods include threaded mounting, interference fit, groove fit, etc., and this application does not limit them.

[0045] This embodiment of the application uses rotatable bite forceps arranged opposite each other, with the bite parts respectively engaging with the upper and lower teeth to open the patient's mouth and achieve an opening function. At the same time, by setting several fixing slots in the fixed base, the movable depressor is fixed in different fixing slots through the fastening part set on the fixed rod, thereby changing the length of the movable depressor outside the fixing slot, thus changing the position of the tongue depressor in the oral cavity. This allows the tongue depressor to match the actual oral structure of different people and improves the stability of the tongue depressor.

[0046] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
