Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to an oral bur box. Background Technology
[0002] Dental burs are commonly used consumables by dentists. They are very thin steel needles consisting of a needle tip and a shank. A set of multiple types of burs is typically stored in a bur case for use, cleaning, and sterilization. Because burs are used inside the patient's mouth, the requirements for cleaning, sterilization, and storage are very strict. Currently, most traditional bur cases do not have a fixed structure inside; they only use a frame with insertion holes to hold the burs in place. However, during cleaning, sterilization, and transport, the burs are easily dislodged from the insertion holes due to shaking or tipping of the bur case. This leads to the burs easily tipping over and scattering during cleaning, sterilization, and transport, often requiring re-sorting and repositioning, which is time-consuming, laborious, and affects the subsequent normal use of the burs. In addition, the shank lengths of sewing needles vary. For example, the standard shank shank length is generally around 13mm, the short shank shank length is around 10.5mm, and the shank lengths of some extended and extra-long shanks are around 19mm-24mm. However, the thickness of the frame inside the existing sewing needle box is fixed, which cannot meet the requirements for stable fixation of sewing needles with different shank lengths. For example, the end of the shank of a sewing needle with a longer shank is far from the fixed position of the frame insertion hole, making it more prone to tipping over in external shaking environments.
[0003] Therefore, it is necessary to design an oral bur box that can at least solve some of the above problems and defects. Utility Model Content
[0004] To solve the above technical problems, this utility model proposes an oral bur box, which has a simple structure and is easy to use. It can hold burs of different specifications and models, and the burs are fixed and placed stably and reliably, effectively avoiding the phenomenon of tipping and scattering during cleaning, disinfection and transportation.
[0005] The technical solution of this utility model is:
[0006] This utility model proposes an oral bur box, including an outer box body with a cavity and a support body disposed in the cavity. The support body includes a top frame and a bottom frame that are movably connected. The top frame is provided with a plurality of first insertion holes arranged at intervals, and the bottom frame is provided with a plurality of second insertion holes arranged at intervals. The second insertion holes are arranged in a one-to-one correspondence with the first insertion holes.
[0007] The bottom of the top layer frame is provided with four vertically fixed columns, which vertically and movably pass through the bottom layer frame. A clamping cylinder is provided in the second insertion hole, and a number of elastic plates evenly spaced along the circumferential direction are provided inside the clamping cylinder.
[0008] Preferably, the top of the elastic sheet is fixedly connected to the inner wall of the clamp cylinder, and its bottom extends toward the central axis of the clamp cylinder;
[0009] The inner wall of the clamp cylinder is provided with a receiving groove that is adapted to the elastic sheet.
[0010] Preferably, the top end of the clamp cylinder is provided with an inverted frustum-shaped circumferential groove, the diameter of the top ring of the circumferential groove is smaller than the outer diameter of the clamp cylinder, and the diameter of the bottom ring of the circumferential groove is equal to the inner diameter of the clamp cylinder.
[0011] Preferably, the clamp cylinder is detachably embedded in the second insertion hole.
[0012] Preferably, the top shelf is provided with a rotating shaft that is vertically and movably connected thereto, and the rotating shaft is rotatably located at the center of the top shelf;
[0013] The rotating shaft extends downward through the top layer frame and passes through the bottom layer frame, and is threadedly connected to the bottom layer frame.
[0014] Preferably, the outer box body includes a box body and a box lid that are movably connected. The side walls of the box body on opposite sides are respectively provided with staggered first through holes, and the side walls of the box lid on opposite sides are respectively provided with staggered second through holes.
[0015] The first through hole on one side wall of the box body coincides with the second through hole on one side wall of the box lid, and the first through hole on the other side wall of the box body coincides with the second through hole on the other side wall of the box lid.
[0016] This utility model has the following advantages and effects compared with the prior art:
[0017] (1) The top and bottom frames are connected by a movable connection, and the distance between the top and bottom frames can be adjusted as needed to accommodate needle shanks of different lengths, ensuring that the needle shanks are fixed stably and reliably, and improving the stability of needle insertion.
[0018] (2) A clamping tube is used in the second insertion hole, and the clamping tube is provided with several elastic plates to press and press against the inserted needle shank, thereby playing the role of clamping and improving the stability of the needle fixation, and avoiding the phenomenon of the needle tilting and scattering or even falling out of the insertion hole due to shaking or vibration during cleaning, disinfection and transportation.
[0019] (3) A bottom frame with a clamping cylinder is used and the bottom frame is movably connected to the top frame to meet different usage scenarios and usage needs. For example, when in normal use, the bottom frame can be adjusted downward to increase the distance between the top frame and the bottom frame. At this time, the needle can be inserted downward through the first insertion hole without inserting the clamping cylinder, which makes it easier to take it out and use later. When cleaning and disinfection are required, the bottom frame can be adjusted upward, and after inserting it through the first insertion hole, a certain external force is applied to insert the needle shank end downward into the clamping cylinder to achieve clamping and fastening. At this time, the needle will not shake or tip over during cleaning, disinfection and transportation. Attached Figure Description

[0027] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.
[0028] Example:
[0029] like Figures 1-6As shown, this utility model provides an oral bur box, which specifically includes an outer box body 1 with a cavity and a support body 2 disposed in the cavity of the outer box body 1. The support body 2 is movably placed in the cavity of the outer box body 1 so that the support body 2 can be taken out of the cavity for separate use or for separate cleaning and disinfection.
[0030] The outer box 1 includes a box body 11 and a box lid 12 that are movably connected. The box body 11 has first through holes 111 that are staggered on opposite side walls. The box lid 12 has second through holes 121 that are staggered on opposite side walls. The first through hole 111 on one side wall of the box body 11 coincides with the second through hole 121 on one side wall of the box lid 12. The first through hole 111 on the other side wall of the box body 11 coincides with the second through hole 121 on the other side wall of the box lid 12. By changing the connection direction between the box lid 12 and the box body 11, the first through hole 111 and the second through hole 121 can be connected or blocked. This allows disinfectant liquid or high-temperature steam to enter the cavity through the through holes to clean or disinfect the interior of the box body 11 and the box lid 12 when the box body 11 and the box lid 12 are closed.
[0031] For details, please refer to Figure 1 As shown, in this embodiment, the lid 12 snaps shut onto the top opening of the box body 11. The left side wall of the box body 11 has two first through holes 111, and the right side wall has three first through holes 111. The two first through holes 111 on the left side and the three first through holes 111 on the right side do not overlap. Similarly, the left side wall of the lid 12 has two second through holes 121, and the right side wall has three second through holes 121. The two second through holes 121 on the left side completely overlap with the two first through holes 111, and the three second through holes 121 on the right side completely overlap with the three first through holes 111. When the lid 12 is closed with its left side wall overlapping the left side wall of the box body 11, the first through holes 111 and the second through holes 121 are completely connected, and the cavity of the outer box body 1 is connected to the external environment. When the lid 12 is closed with its right side wall overlapping the left side wall of the box body 11 (see reference...), Figure 1 (State), the first through hole 111 and the second through hole 121 are not connected, and the cavity of the outer box 1 is in a closed and isolated state.
[0032] Combination Figure 2 and Figure 3As shown, the support body 2 includes a top frame 21 and a bottom frame 22 that are movably connected. The top frame 21 is provided with a number of spaced first insertion holes 211, and the bottom frame 22 is provided with a number of spaced second insertion holes 221. The second insertion holes 221 correspond one-to-one with the first insertion holes 211. A clamping sleeve 4 is embedded inside the second insertion hole 221 so that the needle shank can be fixed by the cooperation between the clamping sleeve 4 inside the second insertion hole 221 and the first insertion hole 211. The bottom of the top shelf 21 is provided with four vertically fixed columns 3, which vertically move through the bottom shelf 22, allowing the bottom shelf 22 to move up and down along the axial direction of the columns 3. This changes the distance between the bottom shelf 22 and the top shelf 21 to adapt to different usage scenarios and needs. For example, during normal use, when the needle needs to be repeatedly picked up and placed, the bottom shelf 22 can be adjusted downwards to increase the distance between the top shelf 21 and the bottom shelf 22. The needle handle only needs to be fixed through the first insertion hole 211 of the top shelf 21, without needing to be inserted into the second insertion hole 221 of the bottom shelf 22, thus facilitating the picking up and placing of the needle. When cleaning and disinfection are required, shaking or flipping is inevitable during cleaning, disinfection, and transportation. In this case, the bottom shelf 22 can be adjusted upwards to reduce the distance between the top shelf 21 and the bottom shelf 22, while ensuring that the end of the needle handle is inserted downwards into the clamping cylinder 4 for clamping and fixing. This improves the stability and reliability of the needle fixing and prevents tipping, scattering, or even detachment during cleaning, disinfection, and transportation.
[0033] Furthermore, such as Figure 2 and Figure 3As shown, the top shelf 21 is equipped with a rotating shaft 5 that is vertically and movably connected to it. The rotating shaft 5 is rotatably positioned at the center of the top shelf 21. The rotating shaft 5 extends downward through the top shelf 21 and passes through the bottom shelf 22, where it is threadedly connected. By rotating the rotating shaft 5, the bottom shelf 22 is driven to reciprocate and move up and down, thereby changing the distance between the top shelf 21 and the bottom shelf 22. This allows for the adaptation of needles with different shank lengths. For example, in actual use, the length of the needle shank generally includes short shank, standard shank, extended shank, and extra-long shank. Different medical staff have different usage habits, and the specific type of needle used needs to be adjusted according to the actual situation for different patients. The length of the shank is important. Existing needles with short shanks are about 10.5mm long, standard shanks are about 13mm long, extended shanks are about 19mm long, and extra-long shanks are about 24mm long. When a set of needles has needles with different shank lengths, it is difficult to fix the needle shanks of different lengths using a single-layer frame of fixed thickness. For example, when the shank length is long, the end of the shank is far away from the fixing hole of the frame, and there may be shaking or tipping. However, in this embodiment, by setting a bottom frame 22 that is movably connected to the top frame 21, the part of the shank near the end is clamped and limited, effectively avoiding shaking or tipping.
[0034] Combination Figure 3 and Figure 4 As shown, a clamping sleeve 4 is embedded inside the second insertion hole 221. Specifically, the clamping sleeve 4 is detachably embedded in the second insertion hole 221 so that the clamping sleeve 4 can be replaced separately without replacing the bottom frame 22 or the entire support body 2, thereby improving the service life of the entire needle box and reducing the cost of use. It should be noted that there is a certain frictional damping between the outer wall of the clamping sleeve 4 and the inner wall of the second insertion hole 221 to ensure that the clamping sleeve 4 will not be moved during the insertion and removal of the needle. At the same time, when the clamping sleeve 4 needs to be replaced, only sufficient external force needs to be applied to make it disengage from the second insertion hole 221.
[0035] Optionally, in some embodiments, the clamp cylinder 4 and the bottom frame 22 are connected in an integral structure.
[0036] refer to Figure 4 , Figure 5 and Figure 6 As shown, the clamp cylinder 4 has several elastic plates 41 evenly spaced along the circumference inside. The top of the elastic plate 41 is fixedly connected to the inner wall of the clamp cylinder 4, and the bottom extends towards the central axis of the clamp cylinder 4 to ensure that the elastic plate 41 is at least partially in contact with the outer wall of the needle shank, thereby playing the role of clamping. Specifically, in this embodiment, the outer diameter of the clamp cylinder 4 is adapted to the second insertion hole 221, the inner diameter of the clamp cylinder 4 is adapted to the first insertion hole 211, and the minimum inner diameter of the elastic plate 41 (the inner diameter of the bottom area) is smaller than the diameter of the needle shank.
[0037] Furthermore, the inner wall of the clamp cylinder 4 is provided with a receiving groove 42 that is compatible with the elastic piece 41, and the elastic piece 41 can be completely embedded in the receiving groove 42 when it is compressed. When the elastic piece 41 loses the pressure force from the needle handle, the elastic piece 41 automatically returns to the outward extension state.
[0038] like Figure 5 and Figure 6 As shown, the top of the clamp cylinder 4 is provided with an inverted frustum-shaped annular groove 43. The diameter of the top ring of the annular groove 43 is smaller than the outer diameter of the clamp cylinder 4, and the diameter of the bottom ring of the annular groove 43 is equal to the inner diameter of the clamp cylinder 4. This serves as a guide when the needle shank is inserted downward into the clamp cylinder 4, thus avoiding the phenomenon that the needle shank is difficult to insert due to tilting.
[0039] In summary, the dental bur box provided by this utility model has a simple structure and is easy to use. It can hold burs of different specifications and models, and the burs are fixed in a stable and reliable manner, effectively avoiding the phenomenon of tipping and scattering during cleaning, disinfection and transportation.
[0040] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
