Abstract
The present disclosure describes dental forceps for transferring dental pulp cell aggregates, comprising two arms, each arm comprising a grip portion, a gripping portion and a tail portion, each gripping portion being provided with a gripping head having a flat surface in any one of the following shapes: circular, oval, quadrilateral, polygonal.
Description
Technical Field
The present disclosure relates to medical devices, and more particularly to dental forceps.
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.
The clamping part of the existing dental forceps which is directly contacted with an object to be clamped is sharp in shape, so that the dental pulp cell aggregate is easy to fall off and damage in the process of transplanting the dental pulp cell aggregate into a root canal after being moved out of a culture dish so as to influence the regeneration effect after the transplantation.

Detailed Description
The dental forceps for transferring dental pulp cell aggregates disclosed in the present invention will be described in further detail with reference to the accompanying drawings and specific examples. 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.
In order to facilitate the clamping and transfer of the membrane-like or sheet-like dental pulp cell aggregates, the clamping portions 110 of the two clamping arms are respectively provided with clamping heads 140 arranged opposite to each other. The gripping head 140 and the arms define an angle therebetween, such as an angle between the shank of the gripping head 140 connected to the arms and the arms in the plane shown in fig. 2 of between 90 degrees and 180 degrees, 100 degrees and 170 degrees, 110 degrees and 160 degrees, 120 degrees and 150 degrees, or 130 degrees and 140 degrees, such that the gripping head 140 extends outwardly, or beyond the length of the arms, to facilitate the gripping of aggregates of endodontic cells. In order to increase the contact area with the dental pulp cell aggregates, the gripping head 140 has a flat surface 141 in any one of the following shapes: circular, elliptical, quadrilateral, polygonal, or any other regular or irregular shape. Preferably, the flat surface 141 is circular in shape. It should be understood that the shapes of the flat surfaces 141 of the gripping heads 140 of the two gripper arms may be identical to or different from each other.
For ease of handling and to substantially conform the shape and size of the planar surface 141 to the shape and size of the dental pulp cell polymer to be clamped, the diameter of the planar surface 141 may be in the range of 2mm to 4mm, preferably 3 mm. It should be understood that the expression "diameter" herein refers to the diameter of the smallest inscribed circle of the profile of the flat surface 141.
In order to allow the forces exerted by the flat surface 141 on the endodontic cell aggregates during the clamping and transfer process to be substantially evenly distributed over the endodontic cell aggregates and to accommodate endodontic cell aggregates of different thicknesses, the gripping head 140 is preferably configured to be rotatable, in particular within certain limits, relative to the gripping portion 110 of the gripping arms. To this end, the gripping head 140 may be hingedly connected to the gripping portion 110. For example, the gripping head 140 may be pivotally connected to, and now rotatable with respect to, a handle portion (as shown in FIG. 2) extending from the gripping portion 110. In one embodiment, the shank portion extends into a cavity formed in the gripping head 140 and is rotatable within the cavity in a form-fit, force-fit, hinged connection, or the like. The rotatability of the gripping head 140, and thus the flat surface 141, with respect to the gripping part 110, is such that when gripping the endodontic cell aggregates, the orientation of the flat surface 141 can be automatically adjusted according to the shape thickness of the gripped endodontic cell aggregates, etc., so that the flat surface 141 is in substantially uniform and complete direct contact with the outer surface of the endodontic cell aggregates, reducing the risk of slipping, injury, etc.
Furthermore, in some embodiments according to the present disclosure, the gripping head 140, and in particular the flat surface 141, may be made of a suitable elastic material to further increase the conformability of the flat surface 141 to the outer surface of the endodontic cell aggregate while further reducing the risk of damaging the endodontic cell aggregate.
Further, in order to further prevent the dental pulp cell aggregates from slipping off the dental forceps 100, an anti-slip structure may be provided in the flat surface 141 of the gripping head 140. The non-slip structure may be embodied as any suitable non-slip structure known in the art, such as an array of raised dots, non-slip channels, a non-slip grid, or the like.
The disclosed dental forceps for transferring a dental pulp cell aggregate reduces the risk of puncturing or damaging the dental pulp cell aggregate when transferring the dental pulp cell aggregate from, for example, a petri dish, by providing a gripping head having a flat surface.
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 forceps for transferring aggregates of dental pulp cells 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.
