Description
Technical Field
The present disclosure relates to medical devices, and more particularly to an obturator.
Background
When the tooth is infected by the pulp and the cell is destroyed due to trauma, decayed tooth or abnormal central point, etc. during the development process of the tooth, the root of the tooth can stop developing. The root apex induction forming operation used in clinic at present uses medicines or operation methods to preserve and induce residual dental pulp at the root apex and soft tissues around the root apex, and promotes the root to continue to develop or forms a calcification barrier to close the root apex. However, the curative effect of the root tip induced plastic surgery depends on the number of living cells remained in the necrotic young permanent teeth, if the periapical inflammation seriously causes the necrosis of a large number of the cells, the periapical tissue can not be reconstructed, and further the development length of the root is insufficient, the wall of the root canal is thin, the shape of the root tip is abnormal, so the clinical curative effect is poor.
Therefore, the development of medical science at present focuses more on the regeneration endodontics, that is, the regeneration of dentin pulp is realized by culturing some dental pulp stem cells in vitro to obtain the formed dental pulp cell aggregates, transplanting the aggregates into the root canal, inducing the stem cells by various growth factors, differentiating into dentin cells and forming the new dental pulp containing the vascular nerve distribution.
For example, CN106890363A discloses a method for preparing engineered dental pulp, in which dental pulp cells from deciduous teeth or constant pressure dental pulp tissue are cultured in vitro to form a membranous dental pulp cell aggregate, whose structure and composition are similar to those of natural dental pulp tissue.
SUMMERY OF THE UTILITY MODEL
In order to further deliver the dental pulp cell aggregates to the deep root canal after the dental pulp cell aggregates are transplanted into the root canal, the present disclosure provides an obturator for the dental pulp cell aggregates.
The disclosed filling device for the dental pulp cell aggregate comprises a handle, a connector and a filling head, wherein a first end of the filling head is connected with the connector, a second end of the filling head is provided with a flat surface, and the filling head is gradually enlarged from the first end of the filling head to the second end of the filling head.
In some embodiments according to the present disclosure, the sides of the filling head are flat surfaces.
In some embodiments according to the present disclosure, the filling head is of a hemispherical structure.
In some embodiments according to the present disclosure, the diameter of the hemisphere of the filling head is in the range of 2mm to 3 mm.
In some embodiments according to the present disclosure, the length of the connector is in the range of 10mm to 20 mm.
In some embodiments according to the present disclosure, the connector is removably secured to the handle.
In some embodiments according to the present disclosure, the connector is in a bent shape.
Drawings
Fig. 1 schematically illustrates a front view of an obturator for endodontic cell aggregates according to the present disclosure;
figure 2 shows in detail the filling head of the filler according to the present disclosure;
figure 3 illustrates in detail another embodiment of the filling head of the obturator according to the present disclosure.
Detailed Description
The filling instrument for endodontic cell aggregates according to the present disclosure will be described in detail with reference to the accompanying drawings and embodiments. Advantages and features of the present invention will become apparent from the following detailed description and claims. It is noted that the drawings are in greatly simplified form and that non-precision ratios are used for convenience and clarity only to aid in the description of the embodiments of the utility model.
An obturator 100 for endodontic cell aggregates according to the present disclosure is described with reference to fig. 1 and 2. The obturator 100 includes a handle 110, a connector 120, and an obturator head 130.
The handle 110 is easy for the user to hold.
The connector 120 has one end fixedly connected to the handle 110 and the other end fixedly connected to the filling head 130. The connector 120 has a length in the range of 10mm to 20mm and a diameter in the range of 1mm to 2 mm. The connecting element 120 has in particular a bent shape, for example the connecting element 120 may comprise two straight sections at an angle to each other, the angle being dimensioned as desired. The connector 120 is removably secured to the handle 110, for example, using connection methods known in the art. So that the connector 120 and the filling head 130 can be replaced as needed, and the connector 120 and the filling head 130 can be separately sterilized.
The filling head 130 is hemispherical and has a flat surface 131. The diameter of the hemisphere of the filling head is in the range of 2mm to 3 mm. The filling head 130 is used to directly contact the dental pulp cell aggregates in the root canal and further deliver the dental pulp cell aggregates deep in the root canal. Of course, the filling head 130 may have a tapered structure, or other structures, as long as the filling head 130 has a shape gradually increasing from the first end of the filling head 130 to the second end of the filling head 130.
In using the filling head 130 of the present disclosure, the user only needs to hold the handle 110 to push the filling head 130 to move, and then push the polymer of dental pulp cells covered on the filling head 130 to move. However, since the dental pulp cell aggregates are sometimes larger in area than the filling head 130, the edge portion of the dental pulp cell aggregates is not pressed by the filling head 130 during the pushing process, so the edge portion of the dental pulp cell aggregates is located at the rear side of the second end of the filling head 130. If the filling head 130 is not gradually enlarged from the first end of the filling head 130 to the second end of the filling head 130, but has another structure, as shown in fig. 3, the polymer of endodontic cells may be adhered to the lateral surface of the filling head and is more difficult to be separated from the filling head 130 due to the restriction of the tip at the middle of the lateral surface of the filling head 130. So that when the user withdraws the filling tip 130 from the pulp chamber, it is highly likely that the cell aggregate will be withdrawn altogether. Like a hemisphere, there is no platform left to prevent the cell aggregate from detaching from the filling head 130, making it more difficult for the cell aggregate to adhere to the back surface.
It should be understood that in the present disclosure, the flat surface of the filling head 130 belongs to the front end of the filling head 130, and the end of the obturator 100 connected to the handle is the rear end.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As used in this disclosure and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
The terms "plurality" and "a plurality" in the present disclosure and appended claims refer to two or more than two unless otherwise specified.
It will be apparent to those skilled in the art that various modifications and variations can be made in the disclosed obturator for endodontic cell aggregates without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
