Description

Technical Field

[0001] This utility model relates to the field of tooth preservation technology, and in particular to a tooth cleaning device and a tooth preservation device that can be used for tooth cell extraction. Background Technology

[0002] Mesenchymal stem cells derived from dental pulp tissue can be isolated from both permanent and deciduous dental pulp. Various cell types can also be extracted from external teeth, serving as a source of cells for scientific research. Because there are virtually no ethical controversies, tooth acquisition is relatively convenient. However, the cleaning and preservation of teeth after extraction or loss are crucial steps for successful tooth cell extraction.

[0003] In the current process of tooth cleaning and preservation, teeth are easily exposed to the external environment and are susceptible to microbial contamination, which can lead to decreased cell activity or even inactivation. Furthermore, due to the lack of fixation, the shaking during transportation may cause the teeth to collide with the container walls, resulting in secondary damage to the dental pulp and potentially leading to failure of tooth cell extraction and culture. Utility Model Content

[0004] To address the technical problems in existing technologies where teeth are easily exposed to the external environment during the transfer process of tooth cleaning and preservation, leading to microbial contamination, decreased cell activity, or even inactivation, and where the lack of fixation during transport can cause collisions between the teeth and the container walls, this invention provides a tooth cleaning device and preservation device for tooth cell extraction.

[0005] The technical solution adopted in this utility model is:

[0006] The first aspect of this application provides a tooth cleaning device for tooth cell extraction, the tooth cleaning device including an external spiral tube and a waste liquid collection tube, the external spiral tube and the waste liquid collection tube being detachably connected, and a tooth placement component being provided inside the external spiral tube;

[0007] The bottom of the outer spiral tube is connected to the waste liquid collection tube. The tooth placement assembly includes a fixing frame and a tooth carrier. The fixing frame is connected to the inner wall of the outer spiral tube, and the tooth carrier is connected to the fixing frame. The tooth carrier has a tooth placement cavity with an open top. The tooth placement cavity has a filter hole with a diameter smaller than the size of the tooth to be treated. The tooth placement cavity is connected to the waste liquid collection tube through the filter hole.

[0008] Preferably, the tooth cleaning assembly further includes a first external spiral tube cap, which is detachably connected to the end of the external spiral tube away from the waste liquid collection tube.

[0009] Preferably, the first external spiral cap is detachably connected to the open end of the waste liquid collection pipe, and the first external spiral cap is used to close the open end of the waste liquid collection pipe.

[0010] Preferably, the external spiral tube, the waste liquid collection tube, and the tooth carrier are all made of transparent material.

[0011] The second aspect of this application provides a tooth preservation device for tooth cell extraction, used in conjunction with the aforementioned tooth cleaning device for tooth cell extraction. The tooth preservation assembly includes a second externally rotating cap and a preservation tube. A tooth limiting member is provided on the second externally rotating cap. The preservation tube is detachably connected to the second externally rotating cap. The second externally rotating cap is also detachably connected to the externally rotating cap after tooth cleaning. The tooth limiting member cooperates with the tooth placement cavity and is used to fix the tooth inside the tooth placement cavity.

[0012] Preferably, the tooth limiting member is in clearance fit with the tooth placement cavity, and the tooth limiting member is used to insert into the tooth placement cavity and abut against the tooth to fix the tooth inside the tooth placement cavity.

[0013] Preferably, the fixing frame is threadedly connected to the external spiral tube, the tooth limiting member is threadedly connected to the tooth placement cavity, the length of the tooth limiting member is greater than the depth of the tooth placement cavity, and the tooth limiting member is used to drive the fixing frame and the tooth placement cavity to move towards the bottom of the storage tube.

[0014] Preferably, the storage tube is made of a transparent material.

[0015] The beneficial effects of this utility model are:

[0016] By detachably connecting the external spiral tube to the waste liquid collection tube, and combining the filter hole design of the tooth placement component, the waste liquid generated during cleaning can flow into the waste liquid collection tube through the filter hole, thereby separating the teeth from the waste liquid, reducing the risk of leakage during the waste liquid treatment process, and reducing the possibility of environmental pollution. At the same time, the teeth remain in the tooth placement cavity during the cleaning process, reducing direct contact with the external environment and helping to reduce the risk of microbial contamination.

[0017] After cleaning, the connection between the outer spiral tube and the waste liquid collection tube can be removed, the storage tube can be connected to the outer spiral tube, and then the second outer spiral tube cap can be connected to the outer spiral tube. This allows the tooth to be directly switched from the cleaning state to the storage state without having to remove the tooth from the tooth placement cavity of the outer spiral tube. This reduces the number of times the tooth is exposed to the external environment and helps to reduce the risk of contamination during the transfer process.

[0018] The tooth limiting device on the second external spiral tube cap works in conjunction with the tooth placement cavity to fix the tooth inside the cavity, reducing the probability of the tooth colliding with the container wall due to shaking during transportation, lowering the risk of secondary damage to the dental pulp tissue, and helping to maintain the activity of tooth cells.

Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0031] Example 1 provides a tooth cleaning device that can be used for tooth cell extraction, such as... Figure 1 and Figure 6 As shown, the tooth cleaning device includes an external spiral tube 1 and a waste liquid collection tube 2. The external spiral tube 1 and the waste liquid collection tube 2 are detachably connected. A tooth placement assembly 3 is provided inside the external spiral tube 1. The bottom of the external spiral tube 1 is connected to the waste liquid collection tube 2. The tooth placement assembly 3 includes a fixing frame 31 and a tooth support 32. The fixing frame 31 is connected to the inner wall of the external spiral tube 1. The tooth support 32 is connected to the fixing frame 31. The tooth support 32 has a tooth placement cavity 321. The top of the tooth placement cavity 321 is open. A filter hole 322 is provided inside the tooth placement cavity 321. The diameter of the filter hole 322 is smaller than the size of the tooth to be treated. The tooth placement cavity 321 is connected to the waste liquid collection tube 2 through the filter hole 322.

[0032] For example, in one possible implementation, the outer spiral tube 1 is made of transparent medical-grade polypropylene and has a hollow tubular structure, such as... Figure 1 As shown, the outer wall of the external spiral tube 1 is machined with a first external thread 11 for connection with the waste liquid collection tube 2; the inner wall of the external spiral tube 1 may be provided with an annular boss (not shown) for supporting the tooth placement assembly 3. The bottom of the external spiral tube 1 is open.

[0033] For example, the waste liquid collection tube 2 can also be made of transparent medical-grade polypropylene, and is a hollow tube with an open top. The inner diameter of the waste liquid collection tube 2 is adapted to the outer diameter of the outer spiral tube 1. The inner wall of the waste liquid collection tube 2 is machined with a first internal thread (not shown in the figure) that matches the external thread of the outer wall of the outer spiral tube 1. The waste liquid collection tube 2 is detachably connected to the outer spiral tube 1 by screwing. The bottom of the waste liquid collection tube 2 is a closed structure for collecting cleaning waste liquid.

[0034] like Figure 1 As shown, the tooth placement assembly 3 includes a fixation frame 31 and a tooth carrier 32. Exemplarily, the fixation frame 31 and the tooth carrier 32 can be manufactured using a one-piece injection molding process (material: transparent medical polyethylene). The fixation frame 31 has an annular structure, and its outer diameter is adapted to the inner wall of the external spiral tube 1. In one embodiment, the fixation frame 31 can be fixedly connected to the annular protrusion of the external spiral tube 1 by an interference fit.

[0035] For example, such as Figure 1 As shown, a tooth placement cavity 321 is formed inside the tooth carrier 32. The top of the tooth placement cavity 321 is open, and filter holes 322 (the diameter of the holes is smaller than the minimum size of the tooth to be treated) are provided on the side walls and bottom of the tooth placement cavity 321, so that the tooth placement cavity 321 is connected to the bottom of the outer spiral tube 1 and the waste liquid collection tube 2 through the filter holes 322.

[0036] In this embodiment, the tooth is placed in the tooth placement cavity 321 of the tooth carrier 32. The cleaning fluid is injected from the top of the outer spiral tube 1 and flows over the tooth surface. The resulting waste fluid seeps through the filter hole 322 into the communication area between the bottom of the outer spiral tube 1 and the waste fluid collection tube 2, and finally collects in the waste fluid collection tube 2. The pore size design of the filter hole 322 prevents the tooth from falling into the waste fluid collection tube 2, achieving separation of the tooth and waste fluid.

[0037] In one possible implementation, such as Figure 3 As shown, the tooth cleaning assembly also includes a first external spiral tube cap 4, which is detachably connected to the end of the external spiral tube 1 away from the waste liquid collection tube 2.

[0038] In one possible implementation, such as Figure 2As shown, the first external spiral cap 4 is detachably connected to the open end of the waste liquid collection pipe 2, and the first external spiral cap 4 is used to seal the open end of the waste liquid collection pipe 2.

[0039] In the specific implementation process, such as Figure 4 As shown, the first external spiral tube cap 4 includes a first connecting part 41 and a second connecting part 42. The second connecting part 42 is located in the middle of the first connecting part 41 and has a protruding structure. A first receiving groove 43 is provided between the first connecting part 41 and the second connecting part 42. The width of the first receiving groove 43 is equal to the sum of the wall width of the waste liquid collection tube 2 and the wall width of the external spiral tube 1.

[0040] For example, such as Figure 4 As shown, the second connecting part 42 is a cylinder, and its outer diameter is adapted to the inner diameter of the outer spiral tube 1. A second external thread 421 is provided on the outer wall of the second connecting part 42, and a second internal thread 12 is provided on the inner wall of the outer spiral tube 1. The second external thread 421 and the second internal thread 12 are adapted to each other.

[0041] like Figure 4 As shown, a third internal thread 411 is provided on the inner side wall of the first connecting part 41, and a third external thread (not shown) is provided on the top outer wall of the waste liquid collection pipe 2. The third internal thread 411 and the third external thread (not shown) are adapted to each other.

[0042] In the specific implementation process, before the tooth cleaning device is used, the first external spiral tube cap 4 is connected to the external spiral tube 1 and the waste liquid collection tube 2 respectively. The external spiral tube 1 is located inside the waste liquid collection tube 2. Specifically, the second external thread 421 of the second connecting part 42 is screwed into the second internal thread 12 on the upper inner wall of the external spiral tube 1. The second connecting part 42 extends into the external spiral tube 1. The first external thread 11 on the outer wall of the external spiral tube 1 is fully screwed into the first internal thread (not shown) on the inner wall of the waste liquid collection tube 2. The external spiral tube 1 extends into the waste liquid collection tube 2, and the two form a connected cavity. The third internal thread 411 of the first connecting part 41 is screwed into the third external thread (not shown) on the upper outer wall of the waste liquid collection tube 2. The first connecting part 41 wraps around the top of the waste liquid collection tube 2. At this time, the first receiving groove 43 just simultaneously accommodates the top wall of the external spiral tube 1 and the top wall of the waste liquid collection tube 2 (because the width of the first receiving groove 43 is equal to the sum of the widths of the two walls). The three form a nested sealing structure.

[0043] When preparing to use the dental cleaning device, hold the first connecting part 41 and rotate it counterclockwise to simultaneously loosen the two sets of threads: the third internal thread 411 of the first connecting part 41 is loosened from the third external thread (not shown) of the waste liquid collection tube 2; the second external thread 421 of the second connecting part 42 is loosened from the second internal thread 12 of the outer rotating tube 1; until the first outer rotating tube cap 4 is completely removed, at which point the top opening of the outer rotating tube 1 and the top opening of the waste liquid collection tube 2 are both exposed (but the outer rotating tube 1 and the waste liquid collection tube 2 are still connected through the first external thread 11 and the first internal thread (not shown)). Hold the tooth with sterile forceps and insert it into the tooth placement cavity 321 of the tooth carrier 32 from the top opening of the outer rotating tube 1, ensuring that the bottom of the tooth fits against the bottom of the cavity and does not block the filter hole 322. The cleaning solution is injected from the top of the outer rotating tube 1 and flows over the tooth surface. The generated waste liquid seeps into the communication area between the bottom of the outer rotating tube 1 and the waste liquid collection tube 2 through the filter hole 322 and finally collects in the waste liquid collection tube 2. After cleaning, hold the upper part of the outer spiral tube 1 (the part exposed to the waste liquid collection tube 2) and keep it fixed. Rotate the waste liquid collection tube 2 counterclockwise to loosen and disengage the first external thread 11 of the outer spiral tube 1 from the first internal thread (not shown) of the waste liquid collection tube 2. Remove the waste liquid collection tube 2 and remove the removed first outer spiral tube cap 4. Screw the third internal thread 411 of the first connecting part 41 clockwise with the third external thread (not shown) of the waste liquid collection tube 2. Tighten the threads to achieve a seal and prevent waste liquid from spilling.

[0044] Example 2 provides a tooth preservation device for tooth cell extraction, which is used in conjunction with the tooth cleaning device for tooth cell extraction in Example 1, such as... Figure 4 and Figure 7 As shown, the tooth preservation assembly includes a second externally rotating tube cap 5 and a preservation tube 6. The second externally rotating tube cap 5 is provided with a tooth limiting member 54. The preservation tube 6 is detachably connected to the second externally rotating tube 1. The second externally rotating tube cap 5 is also used to detachably connect to the externally rotating tube 1 after tooth cleaning. The tooth limiting member 54 cooperates with the tooth placement cavity 321 and is used to fix the tooth inside the tooth placement cavity 321.

[0045] For example, the preservation tube 6 can be made of transparent medical-grade polycarbonate and has a hollow tubular structure. The inner diameter of the preservation tube 6 is adapted to the outer diameter of the outer spiral tube 1. The inner wall of the preservation tube 6 is machined with a fourth internal thread (not shown in the figure) (the pitch is the same as the first external thread 11 of the outer spiral tube 1), which can be screwed into the first external thread 11 of the outer spiral tube 1. The bottom of the preservation tube 6 is a closed structure, and the inside of the preservation tube 6 is pre-filled with cell preservation solution.

[0046] The second external spiral cap 5 is made of transparent medical-grade polypropylene and has an overall cap-like structure. The second external spiral cap 5 includes a third connecting part 51 (outer annular structure), a fourth connecting part 52, and a second receiving groove 53 between the two.

[0047] The fourth connecting part 52 is located at the center of the second outer spiral tube cap 5. It is a cylindrical protrusion. The outer wall of the fourth connecting part 52 is machined with a fifth external thread 521 (the pitch is adapted to the second internal thread 12 on the upper part of the outer spiral tube 1), which can be screwed into the inner wall of the end of the outer spiral tube 1 away from the waste liquid collection tube 2. The tooth limiting member 54 is vertically connected at the center of its bottom end. The axis of the limiting member coincides with the axis of the fourth connecting part 52.

[0048] The third connecting part 51 surrounds the outside of the fourth connecting part 52, and the inner wall is machined with a fifth internal thread 511 (the pitch of which is adapted to the external thread on the upper part of the storage tube 6), which can be screwed into the outer wall of the top of the storage tube 6.

[0049] The second receiving groove 53 is opened between the third connecting part 51 and the fourth connecting part 52. Its width is equal to the sum of the wall width of the outer spiral tube 1 and the wall width of the storage tube 6. It is used to simultaneously accommodate the top tube walls of both, forming a nested seal.

[0050] When the cell preservation fluid level in the preservation tube 6 is high, the tooth placement cavity 321 can be directly immersed in the cell preservation fluid. In one possible implementation, the tooth limiting member 54 is in clearance fit with the tooth placement cavity 321. The tooth limiting member 54 is used to insert into the tooth placement cavity 321 and abut against the tooth to fix the tooth inside the tooth placement cavity 321.

[0051] For example, in this embodiment, the tooth limiting member 54 is a conical silicone protrusion made of medical-grade silicone with a smooth surface. The outer diameter of the tooth limiting member 54 is slightly smaller than the inner diameter of the tooth placement cavity 321. The tooth limiting member 54 forms a clearance fit with the tooth placement cavity 321, and the tooth limiting member 54 can be inserted into the tooth placement cavity 321 and flexibly abut against the tooth surface.

[0052] When the second external spiral tube cap 5 is connected to the external spiral tube 1 and the storage tube 6, the fifth external thread 521 of the fourth connecting part 52 is screwed into the second internal thread 12 of the external spiral tube 1, and the fifth internal thread 511 of the third connecting part 51 is screwed into the external thread of the storage tube 6. The second receiving groove 53 simultaneously locks the top tube wall of the external spiral tube 1 and the storage tube 6. At this time, the tooth limiting member 54 naturally extends into the tooth placement cavity 321 and flexibly abuts against the tooth surface. It is fixed by the elastic deformation of silicone without damaging the tooth tissue.

[0053] When the cell preservation solution level in the preservation tube 6 is low, the tooth placement cavity 321 cannot be directly immersed in the cell preservation solution. In another possible embodiment, the fixing frame 31 is threadedly connected to the external spiral tube 1, and the tooth limiting member 54 is threadedly connected to the tooth placement cavity 321. The length of the tooth limiting member 54 is greater than the depth of the tooth placement cavity 321. The tooth limiting member 54 is used to drive the fixing frame 31 and the tooth placement cavity 321 to move towards the bottom of the preservation tube 6.

[0054] For example, the tooth limiting member 54 is a cylindrical rigid protrusion (made of medical-grade polyethylene), and the tooth limiting member 54 is integrally connected to the bottom end of the fourth connecting part 52; the outer wall of the tooth limiting member 54 is machined with a sixth external thread 541, corresponding to the sixth internal thread 323 on the upper part of the inner wall of the tooth placement cavity 321 (the pitches of the two are matched). The sixth internal thread 323 is only distributed in the upper 1 / 3 area of ​​the inner wall of the tooth placement cavity 321, and its lower end is provided with an annular baffle (not shown) for mechanical limiting; the filter hole 322 is only distributed in the lower 2 / 3 area and bottom of the inner wall of the placement cavity, completely separated from the thread area, ensuring that the flow of cleaning waste liquid is not affected. A medical silicone pad 542 is provided at the front end of the tooth limiting member 54 to buffer the screwing pressure.

[0055] The outer wall of the fixing bracket 31 is machined with a seventh external thread (not shown in the figure), and the inner wall of the external spiral tube 1 is machined with a seventh internal thread 13 at the corresponding position (the pitches of the two are matched), which is used to drive the tooth placement cavity 321 to move down as a whole. In the initial state, the limiting member and the thread of the placement cavity are not in contact; when screwed on, the sixth external thread 541 is pushed along the sixth internal thread 323 until it abuts against the annular stop (not shown in the figure). At this time, the silicone pad just touches the tooth surface lightly (axial pressure 5-10N) to avoid strong compression; continue to rotate the second external spiral tube cover 5, the seventh external thread (not shown in the figure) and the seventh internal thread 13 are engaged, driving the fixing bracket 31 and the placement cavity to move down until they are completely immersed in the preservation fluid.

[0056] In summary, after the teeth are cleaned, when the cell preservation solution level in the preservation tube 6 is high (the liquid level can directly submerge the tooth placement cavity 321), fixation is achieved through the gap fit between the tooth limiting member 54 and the tooth placement cavity 321. The specific transfer steps are as follows:

[0057] After cleaning, hold the upper part of the outer spiral tube 1 (the part exposed outside the waste liquid collection tube 2) and rotate it counterclockwise to remove the waste liquid collection tube 2; align the first external thread 11 of the lower part of the outer spiral tube 1 with the fourth internal thread (not shown) of the upper part of the storage tube 6, and screw it clockwise to secure the connection. At this time, when viewed through the transparent tube wall, the bottom of the tooth placement cavity 321 is close to the surface of the storage liquid. Hold the second outer spiral tube cap 5 and align the fourth connecting part 52 (the central protrusion) with the top opening of the outer spiral tube 1, and the third connecting part 51 (the outer ring structure) with the top opening of the storage tube 6, ensuring that the fifth external thread 521 of the fourth connecting part 52 is aligned with the second internal thread 12 of the outer spiral tube 1, and the fifth internal thread 511 of the third connecting part 51 is aligned with the external thread of the storage tube 6. Rotate the second outer spiral tube cap 5 clockwise, simultaneously engaging the two sets of threads. The fourth connecting part 52 gradually screws into the inner wall of the outer spiral tube 1, and the third connecting part 51 gradually wraps around the outer wall of the top of the storage tube 6 until the second receiving groove 53 completely locks the top walls of the outer spiral tube 1 and the storage tube 6 (due to the groove width matching the sum of the widths of the two tube walls, a tight nesting is formed). Continue screwing, at which point the conical silicone limiting piece at the bottom of the fourth connecting part 52 naturally extends into the tooth placement cavity 321 (due to the outer diameter of the limiting piece being slightly smaller than the inner diameter of the cavity, a clearance fit is formed). The silicone protrusion makes flexible contact with the tooth surface and deforms slightly, fixing the tooth in the cavity through elastic force (without hard compression). When the second outer spiral tube cap 5 can no longer be rotated, the third connecting part 51 and the fourth connecting part 52 form a double seal through the second receiving groove 53, and the tooth placement cavity 321 is completely immersed in the storage solution, and can be placed in a transport box for transport at the required temperature.

[0058] When the cell preservation solution level in the preservation tube 6 is low (the liquid level is lower than the initial position of the tooth placement cavity 321), the tooth placement cavity 321 is moved downwards through the threaded connection. The specific transfer steps are as follows:

[0059] As in Embodiment 1, after removing the waste liquid collection tube 2, screw the first external thread 11 at the lower part of the external spiral tube 1 with the fourth internal thread (not shown) at the upper part of the storage tube 6 for 3-4 turns. At this time, the tooth placement cavity 321 is located above the surface of the storage liquid. Hold the second external spiral tube cap 5 and align the fifth external thread 521 of the fourth connecting part 52 with the second internal thread 12 of the external spiral tube 1, align the fifth internal thread 511 of the third connecting part 51 with the external thread of the storage tube 6, and align the second receiving groove 53 with the top wall of both tubes. Rotate the second external spiral tube cap 5 clockwise, simultaneously engaging the two sets of threads: the fourth connecting part 52 screws into the inner wall of the external spiral tube 1, and the third connecting part 51 wraps around the outer wall of the storage tube 6, until the second receiving groove 53 initially locks the walls of both tubes (not fully tightened). At this time, the lower end of the tooth limiting member 54 (cylindrical hard protrusion) enters the tooth placement cavity 321, and its sixth external thread 541 begins to engage with the sixth internal thread 323 at the upper part of the placement cavity. Continue rotating the second external spiral tube cap 5. The sixth external thread 541 is advanced along the sixth internal thread 323 until the silicone pad at the front end of the limiting member touches the tooth surface, and the thread is screwed to the annular stop (not shown) on the inner wall of the placement cavity. At this time, the axial pressure between the silicone pad and the tooth surface is 5-10N, which just fixes the tooth without causing damage. Keeping the direction of rotation unchanged, continue screwing the second external spiral tube cap 5: because the annular stop (not shown) restricts the limiting member from extending further, the seventh external thread (not shown) on the outside of the fixing bracket 31 and the seventh internal thread 13 on the inner wall of the external spiral tube 1 begin to drive, causing the fixing bracket 31 and the tooth placement cavity 321 to move downward as a whole. Observe through the transparent tube wall until the tooth placement cavity 321 is completely immersed in the preservation fluid, and the bottom of the cavity maintains a distance from the bottom of the preservation tube 6 (to avoid collision). When the second outer spiral tube cap 5 is fully tightened (the third connecting part 51 and the fourth connecting part 52 are sealed by the second receiving groove 53), the teeth are fixed in the immersion placement cavity, forming a closed environment, which can be placed in the transport box for transport at the required temperature.

[0060] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
