Description

Technical Field

[0001] This utility model relates to the field of oral medical device technology, and in particular to a device for dispensing oral medical devices. Background Technology

[0002] Dentists use dental instruments when performing oral treatments on patients. These instruments mainly include irrigators, anesthetic injectors (such as acetaminophen injectors), scalers, forceps, periodontal probes, regular probes, mouth mirrors, and ultrasonic scalers. Therefore, dentists can utilize a variety of dental instruments to provide periodontal treatments tailored to different patient needs.

[0003] Currently, firstly, dentists typically place various dental instruments in a treatment tray during periodontal treatment and retrieve them as needed. However, this method has several drawbacks in practice, such as:

[0004] 1. Traditional treatment trays cannot efficiently and systematically categorize various dental instruments. In other words, the various dental instruments are placed haphazardly in the treatment tray. When dentists need to retrieve the required dental instruments, they have to search through the chaotic array of instruments, which greatly reduces work efficiency and increases labor costs.

[0005] 2. Because some dental instruments have sharp blades or needles, such as the working blade of a scaling instrument or the tip of a periodontal probe, healthcare workers are very likely to be pricked by these instruments when searching for and retrieving the necessary instruments from the various instruments scattered around the treatment tray. This increases the risk of infection for healthcare workers.

[0006] 3. When medical staff search through the various dental instruments scattered in the treatment tray to find and retrieve the necessary dental instruments, the various dental instruments will inevitably collide with each other, which increases the possibility of damage to the dental instruments.

[0007] Secondly, when medical staff (such as dentists and nurses) cooperate to carry out oral and periodontal treatment, they are prone to confusion due to the various oral medical instruments that are arranged in a disorderly manner in the treatment tray. That is, nurses may easily pass the wrong oral medical instruments to dentists, which will affect the smooth progress of the oral and periodontal treatment process, reduce work efficiency, and may even delay the best treatment time due to the wrong or untimely transfer of oral medical instruments, thereby causing harm to patients.

[0008] Therefore, how to efficiently and systematically classify various dental medical devices, reduce the possibility of medical staff being injured by sharp objects and damage to dental medical devices, avoid confusion among various dental medical devices, improve the efficiency of oral and periodontal treatment, and save labor costs has become an urgent problem to be solved.

[0068] In this embodiment, there may be descriptions such as "this device". Those skilled in the art should understand that "this device" refers to a device for configuring oral medical devices provided by this utility model.

[0069] Example 1

[0070] Please refer to Figure 1 This utility model provides a device for configuring dental medical devices, which includes at least a treatment tray body 1, a placement mechanism, a clamping mechanism, and a first locking mechanism, wherein:

[0071] The placement mechanism is installed inside the treatment tray body 1, and the placement mechanism has several dental instrument placement slots 6. Each of the several dental instrument placement slots 6 can be used to place different dental instruments.

[0072] In this embodiment, the cross-section of the treatment disc body 1 can be a cuboid structure, with a length of 25cm, a width of 17cm, and a wall thickness of 1cm.

[0073] In this embodiment, the oral medical devices include, but are not limited to, those known in the art such as irrigators, anesthetic injectors (e.g., methylphenidate injectors), curettes, forceps, periodontal probes, ordinary probes, mouth mirrors, and ultrasonic scalers, which will not be described in detail here.

[0074] Specifically, the placement mechanism includes a placement rod 2 installed on the inner wall of the bottom end of the treatment tray body 1, and several dental medical device placement slots 6 are sequentially opened at the top of the placement rod 2 along the length direction of the placement rod 2. The clamping mechanism is correspondingly set with the placement rod 2.

[0075] In this embodiment, as Figure 1As shown, there can be three rods 2, arranged in parallel and equidistant positions on the inner wall of the bottom end of the treatment disc body 1. For ease of description, [the following text is missing]. Figure 1 The three placement rods 2, from the upper left to the lower right, are named the first placement rod, the second placement rod, and the third placement rod, respectively.

[0076] In this invention, the type of dental medical device placed in the plurality of dental medical device placement slots 6 is not particularly limited. For example, in this embodiment, the specific arrangement of the dental medical device placement slots 6 is as follows:

[0077] 1. Reference Figure 1 The first placement rod has nine dental instrument placement slots 6 from left to right. The first two dental instrument placement slots 6 from left to right are used to place the two arms of the forceps, and the remaining seven dental instrument placement slots 6 are used to place the mouth mirror, periodontal probe, ordinary probe, 5 / 6 type curette, 7 / 8 type curette, 11 / 12 type curette, 13 / 14 type curette and irrigator, respectively.

[0078] 2. Reference Figure 1 The second placement rod has eight dental instrument placement slots 6 from left to right. The eight dental instrument placement slots 6 from left to right are respectively used to place the handle of the ultrasonic scaler, the mouth mirror, the periodontal probe, the ordinary probe, the 5 / 6 type curette, the 7 / 8 type curette, the 11 / 12 type curette, the 13 / 14 type curette and the Bilan anesthetic syringe.

[0079] 3. Reference Figure 1 The third placement rod has eight dental instrument placement slots 6 from left to right. The eight dental instrument placement slots 6 from left to right are used to place the handle of the ultrasonic scaler, mouth mirror, periodontal probe, ordinary probe, 5 / 6 type curette, 7 / 8 type curette, 11 / 12 type curette, 13 / 14 type curette and Bilan anesthetic syringe.

[0080] In this embodiment, the shape of the dental medical device placement slot 6 is not particularly limited. That is, as long as the multiple dental medical device placement slots 6 can be adapted to the shape of the dental medical device placed inside them to ensure the stability of the dental medical device during placement.

[0081] Furthermore, the oral medical device placement slot 6 is provided with an anti-slip layer (not shown in the figure) that conforms to its shape. Preferably, this anti-slip layer can be made of high-temperature resistant silicone rubber or other materials known in the art, and is not particularly limited here.

[0082] In this embodiment, the placement mechanism is provided with a labeling area (not shown in the figure), which can be used to classify different dental medical devices. Preferably, the labeling area can be located on the placement rod 2.

[0083] In this invention, the specific structure of the marking area is not particularly limited, as long as it can classify different dental medical devices. For example, in this embodiment, the marking area can be different colors set on the placement rod 2 or in the dental medical device placement slot 6 to classify different dental medical devices.

[0084] More specifically, for example, different high-temperature resistant pigments can be coated into the dental instrument placement slots 6 for placing the scrapers to distinguish different models of scrapers. The scrapers can be those disclosed in Chinese Utility Model Patent Publication No. CN222917624U, the contents of which are incorporated herein by reference in their entirety. Since the different models of scrapers in the aforementioned patent have different colors, the four dental instrument placement slots 6 in this device can be coated with the same color as the different models of scrapers in the aforementioned patent, thereby achieving the classification of different models of scrapers. This allows for rapid differentiation of different models of scrapers and improves work efficiency.

[0085] Furthermore, those skilled in the art should understand that the marking area can also be in a more intuitive form, such as text or patterns. For example, text information corresponding to each dental instrument placement slot 6 can be engraved on the placement rod 2, such as engraving corresponding text descriptions on both sides of the dental instrument placement slots 6 for 5 / 6 and 7 / 8 scalers, thereby distinguishing different dental instruments. As another example, the pattern of the dental instrument corresponding to each dental instrument placement slot 6 can be drawn on the inner wall of the bottom of the treatment tray body 1 using high-temperature resistant pigment, thereby distinguishing different dental instruments.

[0086] According to one embodiment of the present invention, both the clamping mechanism and the first locking mechanism are mounted on the treatment tray body 1, with the clamping mechanism corresponding to the placement mechanism. The first locking mechanism is used to lock the clamping mechanism to the treatment tray body 1, thereby clamping and fixing the oral medical device placed in the oral medical device placement slot 6.

[0087] Specifically, refer to Figure 1 and Figure 6 The clamping mechanism includes a clamping plate 7 hinged to the treatment tray body 1 (e.g., hinged together using a hinge known in the art), the clamping plate 7 being disposed correspondingly to the placement rod 2, and a buffer layer 8 being installed at the bottom end of the clamping plate 7.

[0088] In this embodiment, since there are three placement rods 2, there are also three clamping plates 7, which are sequentially arranged corresponding to the three placement rods 2. Both the clamping plates 7 and the placement rods 2 can be cuboid or similar structures, and their widths can be the same. The buffer layer 8 can also be a cuboid structure, and its width can be the same as the width of the clamping plates 7.

[0089] In this embodiment, the clamping plate 7 can clamp and fix the dental medical devices in the dental medical device placement slot 6, thereby preventing the dental medical devices from falling out of the slot 6. For example, when the dental medical devices in this device are transported, the unavoidable bumps during transportation can easily cause the dental medical devices to fall out of the placement slot 6. This can not only cause the dental medical devices to collide with each other on the treatment tray body 1, increasing the possibility of damage to the dental medical devices, but also cause confusion between different medical devices. However, by setting up the clamping plate 7, the dental medical devices can be firmly clamped and fixed in the placement slot 6 during transportation, thereby avoiding the above-mentioned situation.

[0090] Preferably, the buffer layer 8 can also be made of high-temperature resistant silicone rubber or other materials known in the art, and is not particularly limited herein. By providing the buffer layer 8, direct contact between the clamping plate 7 and the dental medical device is avoided when the clamping plate 7 clamps and fixes the device, thus preventing damage to the device due to compression and extending its service life. The high-temperature resistant silicone rubber material is non-toxic and odorless, and will not have any adverse effects on the oral environment or human health. It also possesses high-temperature resistance and corrosion resistance, maintaining stable performance during routine sterilization processes, and therefore will not affect the normal use of the device.

[0091] In this embodiment, as Figure 6 As shown, a first torsion spring 10 is installed at the hinge joint between the pressure plate 7 and the treatment plate body 1 (i.e., the hinge between the pressure plate 7 and the treatment plate body 1), and the two ends of the first torsion spring 10 are respectively connected to the pressure plate 7 and the treatment plate body 1.

[0092] Specifically, the first torsion spring 10 can be integrally sleeved on the hinge between the pressure plate 7 and the treatment disc body 1, and its two ends can be connected to the pressure plate 7 and the treatment disc body 1 by any means known in the art (e.g., bolt connection). When the pressure plate 7 is pressed downwards (i.e., when the pressure plate 7 is pressed downwards...), Figure 6When the clamping plate 7 rotates counterclockwise, the first torsion spring 10 stores elastic potential energy, thereby enabling the clamping plate 7 to automatically spring up, facilitating its use by medical staff. Simultaneously, when the first locking mechanism does not lock the clamping plate 7, it remains open under the action of the first torsion spring 10, ensuring that medical staff can retrieve dental instruments from the dental instrument placement slot 6 without hindering their work and guaranteeing the normal operation of dental procedures.

[0093] Furthermore, such as Figure 6 As shown, the treatment tray body 1 has an expansion groove 9, which is adapted to the clamping plate 7 (i.e., the width of the expansion groove 9 is the same as the width of the clamping plate 7) and is correspondingly set with the clamping plate 7. The expansion groove 9 is configured to allow the opening angle between the clamping plate 7 and the bottom end of the treatment tray body 1 to be greater than 90°.

[0094] In this embodiment, since there are three clamping plates 7, there are also three expansion slots 9, which are arranged one-to-one with the three clamping plates 7. The specific structure of the expansion slots 9 can be found in [reference needed]. Figure 6 It can be a cuboid structure.

[0095] In this embodiment, as Figure 6 As shown, the clamping plate 7 can be hinged to the top of the inner wall of the treatment tray body 1, and the expansion groove 9 can be connected to the interior of the treatment tray body 1. This allows the clamping plate 7 to enter the expansion groove 9, achieving an opening angle greater than 90° between the clamping plate 7 and the bottom of the treatment tray body 1. Through this arrangement, the opening angle between the clamping plate 7 and the bottom of the treatment tray body 1 can reach 130°-160°, thus preventing the clamping plate 7 from obstructing medical personnel from placing dental instruments in the dental instrument placement slot 6.

[0096] According to one embodiment of the present invention, the first locking mechanism can be used to lock the pressure plate 7 to the treatment tray body 1, so as to press and fix the oral medical device placed in the oral medical device placement slot 6.

[0097] Specifically, such as Figure 4 As shown, the first locking mechanism includes a second locking rod 13, which can extend entirely through the side wall of the treatment disc body 1 and slide slidably connect with the side wall of the treatment disc body 1. Figure 9 As shown, the second locking rod 13 is located at one end inside the treatment disc body 1 (i.e., Figure 9 The left end of the second locking lever 13, that is Figure 4 The right end of the second locking rod 13 has a U-shaped groove 16 in the horizontal direction. The end of the second locking rod 13 located outside the treatment disc body 1 (i.e. Figure 4 The left end of the second locking lever 13, that is Figure 9The first button 15 is installed on the right end of the second locking rod 13.

[0098] In this embodiment, the second locking rod 13 is preferably a square rod structure, and the opening direction of the U-shaped slot 16 faces the first button 15.

[0099] like Figure 4 As shown, a first spring 14 is sleeved on the second locking rod 13, and the two ends of the first spring 14 are fixedly connected to the outer wall of the treatment disc body 1 and the first button 15, respectively.

[0100] In this embodiment, the fixed connection method between the first spring 14 and the outer wall of the treatment disc body 1, and between the first spring 14 and the first button 15, is not particularly limited, and they can all be connected by bolts.

[0101] Reference Figure 5 A first locking rod 11 is installed on the pressure plate 7. A first locking groove 12 is formed on the bottom side wall of the first locking rod 11. The first locking groove 12 is correspondingly provided with a U-shaped slot 16 and is adapted to fit the U-shaped slot 16. The first locking groove 12 is configured to engage with the U-shaped slot 16 to lock the pressure plate 7 and the treatment tray body 1.

[0102] In this embodiment, as Figure 5 As shown, the first locking rod 11 can be a square rod structure and is arranged perpendicular to the pressure plate 7. The first locking rod 11 can be located at the end of the pressure plate 7 away from the first torsion spring 10. The opening direction of the first locking groove 12 is oriented towards the first torsion spring 10, and the first locking groove 12 can be a square groove structure.

[0103] Furthermore, such as Figure 9 As shown, the top of the U-shaped slot 16 can be an inclined structure, and the inclined surface of this inclined structure faces the outside of the treatment disc body 1.

[0104] Reference Figure 1 When it is necessary to clamp and fix the oral medical device placed in the oral medical device placement slot 6, the medical staff can press down the clamping plate 7 and make the clamping plate 7 rotate counterclockwise around the first torsion spring 10. Figure 1The first locking rod 11 is rotated counterclockwise until it contacts the inclined structure at the top of the U-shaped groove 16. Since the inclined structure at the top of the U-shaped groove 16 faces the outside of the treatment tray body 1, the second locking rod 13 will automatically move towards the inside of the treatment tray body 1 under the pressure of the first locking rod 11, without the need for medical staff to manually press the second locking rod 13. At the same time, the first spring 14 will be compressed until the U-shaped groove 16 and the first locking groove 12 are engaged with each other. Then, the second locking rod 13 will automatically return to its initial position under the elastic potential energy of the first spring 14. This achieves the locking of the pressure plate 7 and the treatment tray body 1, thereby achieving the pressing and fixing of the oral medical device in the oral medical device placement slot 6. Conversely, when it is necessary to open the clamping plate 7, i.e., to retrieve an oral medical instrument from the dental instrument placement slot 6, simply press the first button 15 towards the inside of the treatment tray body 1. At this time, the U-shaped slot 16 will disengage from the first locking groove 12, and the clamping plate 7 will automatically return to its initial position under the elastic potential energy stored in the first torsion spring 10, without requiring medical personnel to manually lift the clamping plate 7. Therefore, the inclined structure at the top of the U-shaped slot 16 and the setting of the first torsion spring 10 can greatly improve convenience and work efficiency.

[0105] In this embodiment, as Figure 1 As shown, two cotton ball placement slots 5 are also provided inside the treatment tray body 1. Preferably, with Figure 1 Taking the top view of the treatment tray body 1 from the lower left to the upper right corner as an example, the two cotton ball placement slots 5 can be set on the left and right sides inside the treatment tray body 1, respectively.

[0106] Specifically, the cotton ball placement slot 5 can be a cuboid structure. The cotton ball placement slot 5 on the left side inside the treatment tray body 1 can be used to place clean, sterilized cotton balls required during the dental procedure, while the cotton ball placement slot 5 on the right side inside the treatment tray body 1 can be used to place contaminated sterilized cotton balls used during the dental procedure.

[0107] In this embodiment, as Figure 1 As shown, an irrigation fluid storage tank 3 and a needle cap placement tank 4 are also provided inside the treatment tray body 1. Preferably, with Figure 1 Taking the top view of the treatment tray body 1 from the lower left to the upper right corner as an example, the rinsing fluid storage tank 3 and the needle cap placement tank 4 can be set in the upper left and upper right corners of the treatment tray body 1, respectively.

[0108] Specifically, the rinsing solution storage tank 3 can be used to store rinsing solutions such as hydrogen peroxide or chlorhexidine required during oral medical procedures. It can be square in shape and can be configured to hold approximately 5 ml of rinsing solution. With the rinsing solution storage tank 3, medical staff can easily draw rinsing solution from the tank using an rinsing device, improving work efficiency.

[0109] The needle cap placement slot 4 can be used to place the oral disposable injection needle cap used with the Bilan anesthetic syringe. For example, after medical staff administer anesthetic to a patient using the oral disposable injection needle on the Bilan anesthetic syringe, they need to recap the oral disposable injection needle. With the needle cap placement slot 4, medical staff only need to press the oral disposable injection needle cap in the needle cap placement slot 4 to complete the cap recapping, which improves work efficiency and avoids the risk of being pricked by the oral disposable injection needle, thus ensuring the personal safety of medical staff.

[0110] In addition, when no disposable oral injection needle cap is placed in the needle cap placement slot 4, medical staff can place the handle plate of the Bilan anesthetic syringe (i.e., the protruding ear-shaped structure on the Bilan anesthetic syringe) in the needle cap placement slot 4, and at the same time place the end of the Bilan anesthetic syringe in the oral medical device placement slot 6 on the second placement rod. At this time, the Bilan anesthetic syringe will be in an inclined state, which can improve the convenience of picking up the Bilan anesthetic syringe during oral medical work, thereby improving work efficiency.

[0111] In this embodiment, as Figure 1 As shown, two tweezers placement grooves 31 are provided on the side wall of the treatment tray body 1, and the tweezers placement grooves 31 are correspondingly arranged with the oral medical instrument placement slots 6 for placing tweezers. Since tweezers need to be frequently picked up during oral medical work, the tweezers placement grooves 31 allow the tweezers to be placed in the grooves during oral medical work. At this time, the tweezers will be in an inclined position, thereby improving the convenience of picking up the tweezers and thus improving work efficiency.

[0112] In this embodiment, as Figure 1As shown, a tail wire placement groove 32 is also provided on the side wall of the treatment tray body 1. The tail wire placement groove 32 can be used to place the power supply wire of the ultrasonic scaler, and the tail wire placement groove 32 is correspondingly set with the dental instrument placement slot 6 for placing the handle of the ultrasonic scaler. Since the ultrasonic scaler needs to be connected to the power supply wire for power supply during use, when the ultrasonic scaler is placed in the dental instrument placement slot 6, its connected power supply wire will interfere with the side wall of the treatment tray body 1. Therefore, the tail wire placement groove 32 can avoid the interference between the power supply wire and the side wall of the treatment tray body 1, ensuring the normal operation of dental medical work.

[0113] In this embodiment, the device is for single use. Specifically, except for the first spring 14 and the first torsion spring 10, all components of the device can be made of materials known in the art, such as high-strength and puncture-resistant polypropylene (PP) and polyethylene (PE), to form a multi-layer composite structure. They can also be made of materials known in the art, such as biodegradable plastics (e.g., PLA) or starch-based materials, to achieve better environmental protection. The first spring 14 and the first torsion spring 10 can be made of medical-grade stainless steel such as 304 stainless steel, and the inner wall of the treatment tray body 1 can be made of materials known in the art, such as food-grade polyethylene terephthalate (PET), without special limitations. When manufactured, the device can be packaged using aseptic packaging known in the art, and can be used directly after unpacking when needed. After use, it can be disposed of as medical waste, thereby effectively avoiding the risk of cross-infection.

[0114] Alternatively, an antibacterial coating known in the art can be applied to the surface of this disposable device to achieve a better antibacterial effect, which will not be elaborated here.

[0115] Furthermore, in this embodiment, the device can also be reused. Specifically, the device can be made entirely of medical-grade stainless steel such as 304 stainless steel. After use, the dental medical instruments to be sterilized can be placed in the dental medical instrument placement slot 6, and then the clamping plate 7 can be used to press and fix the dental medical instruments. Finally, the used dental medical instruments and the device can be thoroughly cleaned to remove surface dust and impurities. Then, the device can be sterilized by high-temperature and high-pressure steam according to the standard operating procedures of the hospital's sterilization supply center. After sterilization, it can be stored in a sterile storage cabinet and is ready for the next use.

[0116] Additionally, nanotechnology (known in the art) can be used to treat the surface of the stainless steel device, thereby further reducing the risk of bacterial growth and device contamination, and also extending the service life of the device.

[0117] Example 2

[0118] In this embodiment, the device is reusable, meaning it can be entirely made of medical-grade stainless steel such as 304 stainless steel. Compared to Embodiment 1, this embodiment also adds the following:

[0119] Reference Figure 2 The bottom of the treatment disc body 1 has a hollow structure.

[0120] In this embodiment, the specific shape of the hollow structure on the treatment disc body 1 is not particularly limited, as long as it can achieve the hollow effect of the treatment disc body 1. For example, the hollow structure on the treatment disc body 1 can be a number of oval elongated through holes opened at the bottom end of the treatment disc body 1.

[0121] In this embodiment, as Figure 2 , Figure 7 and Figure 10 As shown, this device also includes a tray 17 (see details). Figure 15 A second locking mechanism is installed on the tray 17 to lock the tray 17 to the bottom outer wall of the treatment tray body 1, so as to catch the liquid dripping from the hollow structure of the treatment tray body 1 during the use of the treatment tray body 1 (i.e. during the oral medical work), thereby preventing the liquid dripping from the hollow structure of the treatment tray body 1 from polluting the external environment.

[0122] Specifically, such as Figure 3 As shown, the second locking mechanism includes a locking plate 18 installed (which may be bolted) on the outer side wall of the tray 17, and the top of the locking plate 18 is higher than the top of the tray 17. A second locking groove 19 is provided on the top of the locking plate 18.

[0123] In this embodiment, as Figure 3 As shown, the locking plate 18 can be a flat cuboid structure or a generally flat cuboid structure. For example... Figure 15 As shown, there can be two locking plates 18, which are installed symmetrically on the two opposite outer walls of the tray 17.

[0124] In this embodiment, as Figure 3 As shown, the second locking groove 19 can be a through groove structure, and the bottom of the second locking groove 19 is a circular structure, while its top is a rectangular structure connected to the outside of the locking plate 18. For ease of description, the circular part of the second locking groove 19 is named the circular second locking groove, and the rectangular part of the second locking groove 19 is named the rectangular second locking groove. The rectangular second locking groove is connected to the circular second locking groove.

[0125] The upper limit of the side wall of the treatment disc body 1 is connected to a locking block 21 ( Figure 3 Not shown in the image, please refer to the image below. Figure 14 The locking block 21 is configured to enter the second locking groove 19 and be able to lock itself to the second locking groove 19 by rotation, so as to lock the tray 17 to the bottom outer wall of the treatment tray body 1.

[0126] In this embodiment, the limiting rotational connection between the locking block 21 and the side wall of the treatment disc body 1 is a friction drive connection (also known as a damped rotational connection) known in the art, for example, as... Figure 14 As shown, a locking block rotating shaft is coaxially mounted on the locking block 21 (i.e., at the center of the locking block 21). A locking block rotating hole (not shown in the figure) adapted to the locking block rotating shaft is provided on the side wall of the treatment disc body 1. The locking block rotating shaft and the locking block rotating hole are interference-fitted to each other, thereby realizing the friction transmission connection between the two.

[0127] Specifically, refer to Figure 14 The locking block 21 can be a cuboid structure, and both wide sides of the locking block 21 are arc-shaped structures with their centers at the center of the locking block 21. Preferably, the width of the locking block 21 is the same as the width of the rectangular second locking groove, and the radius of the arc-shaped structure of the locking block 21 is the same as the radius of the circular second locking groove.

[0128] Preferably, the thickness of the locking block 21 is the same as the groove thickness of the second locking groove 19.

[0129] During dental procedures, dental instruments may become contaminated with various liquids (such as rinsing solutions, patient saliva, or blood). If these liquid-laden instruments are placed inside the treatment tray body 1, the liquid will drip from the perforated structure of the treatment tray body 1 onto the outside, potentially contaminating the external environment. Therefore, a tray 17 needs to be pre-installed on the bottom outer wall of the treatment tray body 1 to catch any dripping liquid, effectively preventing environmental contamination. When connecting the tray 17 to the bottom outer wall of the treatment tray body 1, the two straight edges of the locking block 21 can be twisted vertically, allowing the locking block 21 to extend into the circular second locking groove through the rectangular second locking groove. Then, rotating the locking block 21 90° clockwise or counterclockwise causes its curved edge to abut against the inner wall of the circular second locking groove, thus locking the tray 17 to the treatment tray body 1 and connecting them. When it is necessary to remove it, repeat the above operation in reverse to separate the tray 17 from the treatment tray body 1.

[0130] Furthermore, referring to Figure 3 and Figure 14A knob 20 is coaxially connected to one end of the locking block 21 away from the treatment disc body 1. The shape of the knob 20 is preferably the same as that of the locking block 21, and the volume of the knob 20 is larger than that of the locking block 21. Several anti-slip grooves are provided on the outer wall of the knob 20 along its circumference.

[0131] In this embodiment, since the volume of the knob 20 is larger than that of the locking block 21, it facilitates the rotation of the locking block 21 and also saves effort. However, because the knob 20 obstructs the locking block 21, medical staff cannot easily determine its status. By matching the shape of the knob 20 to that of the locking block 21, medical staff can determine the status of the locking block 21 in real time based on the state of the knob 20, thus improving work efficiency.

[0132] In this embodiment, the anti-slip groove can increase the friction between the medical staff's hands and the knob 20, thereby making it easier for the medical staff to turn the locking block 21.

[0133] According to one embodiment of the present invention, referring to... Figure 2 , Figure 7 and Figure 10 A top cover 22 is hinged to the treatment tray body 1 (e.g., using a hinge known in the art). The top cover 22 is configured to completely cover the top of the treatment tray body 1, and preferably, the cross-sectional area and shape of the top cover 22 are the same as those of the treatment tray body 1. For example, Figure 2 As shown, the top cover 22 also has a hollow structure.

[0134] In this embodiment, the hollow structure on the top cover 22 can be multiple oval elongated through holes, which are not particularly limited here.

[0135] In this embodiment, the top cover 22 provides protection for the dental instruments placed on the treatment tray body 1, preventing damage from external impacts. Specifically, when performing high-temperature sterilization on the device and its internal dental instruments, the dental instruments are first placed in the dental instrument placement slot 6, and the clamping plate 7 is used to press and fix the instruments. Then, the top cover 22 is placed on top of the treatment tray body 1, thus providing protection for the dental instruments. Since both the top cover 22 and the treatment tray body 1 are perforated, high-temperature steam can enter the interior of the treatment tray body 1 through these perforations, thereby sterilizing the interior of the treatment tray body 1 and the dental instruments inside.

[0136] Furthermore, such as Figure 7 and Figure 8As shown, a second torsion spring 30 is installed at the hinge between the treatment tray body 1 and the top cover 22, and the two ends of the second torsion spring 30 are connected to the top cover 22 and the treatment tray body 1, respectively.

[0137] In this embodiment, as Figure 8 As shown, the second torsion spring 30 can be integrally sleeved on the hinge between the treatment disc body 1 and the top cover 22, and the two ends of the second torsion spring 30 can be connected to the top cover 22 and the treatment disc body 1 respectively by bolt connection, without special limitation.

[0138] According to one embodiment of the present invention, a third locking mechanism is installed on the treatment tray body 1. The third locking mechanism is configured to lock the top cover 22 to the treatment tray body 1, thereby protecting the oral medical device placed in the oral medical device placement slot 6.

[0139] Specifically, such as Figure 2 , Figures 11-13 As shown, the third locking mechanism includes at least a locking housing 24 mounted on the treatment tray body 1, with the top of the locking housing 24 aligned with the opening and closing direction of the top cover 22 (i.e., Figure 12 A third locking groove 25 is provided in the vertical direction of the middle. Figure 2 , Figure 7 and Figure 10 As shown, a third locking rod 23 is installed on the top cover 22. The third locking rod 23 is adapted to the third locking groove 25 (that is, the width of the third locking groove 25 and the third locking rod 23 are the same) and are set accordingly.

[0140] In this embodiment, the locking box 24 can be a square structure, and it can be installed on the outer wall of the treatment tray body 1 by means of bolt connection.

[0141] like Figure 12 As shown, a fourth locking rod 26 is slidably installed inside the locking housing 24, with the end of the fourth locking rod 26 near the third locking groove 25 (i.e., Figure 12 The left end of the fourth locking rod 26 is located in the third locking groove 25. The third locking rod 23 is configured to abut against the bottom end of the fourth locking rod 26 to lock the top cover 22 to the treatment plate body 1. That is, there is a certain distance between the bottom end of the fourth locking rod 26 and the bottom end of the third locking groove 25, and this distance is greater than or equal to the width of the third locking rod 23, preferably equal to the width of the third locking rod 23.

[0142] In this embodiment, the fourth locking rod 26 can be a cylindrical structure. It can be positioned along the locking housing 24. Figure 12 A fourth locking rod sliding hole, adapted to the fourth locking rod 26, is opened in the horizontal direction, and the fourth locking rod sliding hole is connected to the third locking groove 25. When Figure 12 When the left end of the fourth locking rod 26 contacts the left inner wall of the third locking groove 25, the distance between the right end of the fourth locking rod 26 and the right end of the fourth locking rod sliding hole is greater than or equal to the groove width of the third locking groove 25. This allows the fourth locking rod 26 to slide completely away from the interior of the third locking groove 25, preventing the top end of the fourth locking rod 26 from blocking the third locking rod 23, thereby enabling the top cover 22 to lock properly with the treatment disc body 1.

[0143] Furthermore, such as Figure 12 As shown, the third locking mechanism also includes a pressing rod 27 that is slidably installed in the locking housing 24.

[0144] In this embodiment, the pressing lever 27 can be located directly below the fourth locking lever 26. Specifically, it can be positioned along the locking housing 24. Figure 12 A sliding hole for the pressing rod 27 is opened in the horizontal direction, and the sliding hole for the pressing rod is connected to the outside of the locking box 24. When the pressing rod 27 is fully located in the sliding hole for the pressing rod, the distance between the left side of the pressing rod 27 and the left side of the sliding hole for the pressing rod is greater than or equal to the groove width of the third locking groove 25.

[0145] like Figure 13 As shown, a first rack 34 is mounted on the fourth locking rod 26, and a second rack 35 is mounted on the pressing rod 27. A gear 33 is rotatably mounted inside the locking housing 24, with the first rack 34 and the second rack 35 meshing at the two ends of the gear 33, respectively. The end of the pressing rod 27 furthest from the locking housing 24 is located outside the locking housing 24 and has a second button 29 mounted on it. A second spring 28 is sleeved on the pressing rod 27, with both ends of the second spring 28 fixedly connected to the outer wall of the locking housing 24 and the second button 29, respectively.

[0146] When it is necessary to lock the top cover 22 to the treatment tray body 1, it can be done by... Figure 12 Press the second button 29 on the left side. The gear 33 will rotate clockwise, allowing the third locking rod 23 to be positioned between the fourth locking rod 26 and the bottom of the third locking groove 25. Then release the second button 29. The fourth locking rod 26 will return to its initial position under the force of the second spring 28, thus locking the top cover 22 to the treatment tray body 1. To unlock the top cover 22 from the treatment tray body 1, press the second button 29 on the left side. Figure 12 Press the second button 29 on the left side, and the top cover 22 will automatically open under the elastic potential energy stored in the second torsion spring 30, thus making it easy to unlock the top cover 22 from the treatment tray body 1.

[0147] Furthermore, such as Figure 11 and Figure 12As shown, the end of the fourth locking rod 26 located within the third locking groove 25 (i.e., the left end of the fourth locking rod 26) is an inclined structure, and the inclined surface of this inclined structure faces... Figure 12 The top left corner. Through this tilted structure, when it is necessary to lock the top cover 22 to the treatment tray body 1, pressing down on the top cover 22 will automatically cause the fourth locking lever 26 to move towards the upper left corner. Figure 12 The rightward movement (i.e., the third locking lever 23 will contact and press this tilting structure) eliminates the need for manual pressing of the second button 29, bringing convenience and improving work efficiency.

[0148] In the above embodiments, the edges of the treatment tray body 1 and the top cover 22 are rounded to prevent sharp edges from causing accidental injury to patients or medical staff, and also to prevent sharp edges from hitting and damaging the dental medical instruments.

[0149] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0150] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
