Description

Special dental forceps for intention replantation

Technical Field

The utility model relates to a medical appliance, in particular to a special dental forceps for intention replantation.

Background

The intention dental replantation is a technique of completely extracting the difficult and difficult affected teeth which are difficult to cure by the conventional method, then implanting the difficult and difficult affected teeth into the original dental socket after a series of diagnosis, examination and treatment in vitro to retain the natural teeth. In the process of the intention replanting operation, the affected tooth needs to be completely pulled out and then the in vitro affected tooth is subjected to inverted preparation and inverted filling, the in vitro time of the affected tooth in the in vitro operation process is shortened as much as possible, and the direct touch on the surface of the tooth root is avoided.

At present, the method for fixing the teeth only comprises the steps of pinching by hands or clamping by using a pair of tooth forceps, the dental crowns are not easy to pinch stably when the dental crowns are held by hands for operation, and the hands have certain danger when a high-speed mobile phone is used for cutting roots; when the tooth extracting forceps are used for corresponding operation, most of the affected teeth needing to be implanted intentionally are fragile in the dental crown part of the affected teeth after root canal treatment, the tooth extracting forceps can clamp the dental crown of the affected teeth to be broken when large force is used, and the tooth extracting forceps can not well fix the in-vitro affected teeth when small force is used, so that the affected teeth can move and even fall off to cause pollution in the in-vitro operation process, the clinical operation time is finally delayed, and the intended implantation failure is even caused.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems, the special dental forceps for the intention replantation, which has a simple structure and is convenient to use, is provided.

The specific technical scheme is as follows:

the special dental forceps for the purpose of replantation comprise a first forceps body and a second forceps body, wherein a first finger sleeve part is arranged on the first forceps body, a second finger sleeve part is arranged on the second forceps body, the middle part of the first forceps body is pivoted with the second forceps body through a pin shaft, the special dental forceps are characterized by further comprising a first forceps head and a second forceps head, the bottoms of the first forceps head and the second forceps head are respectively connected to the first forceps body and the second forceps body in a one-to-one correspondence mode, and the longitudinal sections of the first forceps head and the second forceps head are arc-shaped.

The special dental forceps for the intended replantation is further characterized in that a plurality of first anti-slip lines are arranged on the side wall, facing the second forceps head, of the first forceps head at intervals, the first anti-slip lines extend along the height direction of the first forceps head, a plurality of second anti-slip lines are arranged on the side wall, facing the first forceps head, of the second forceps head at intervals, and the second anti-slip lines extend along the height direction of the second forceps head.

The special dental forceps for the intended replantation is further characterized by further comprising a first forceps head sleeve and a second forceps head sleeve, wherein the first forceps head sleeve and the second forceps head sleeve are respectively sleeved on the first forceps head and the second forceps head in a one-to-one correspondence mode, and the first forceps head sleeve and the second forceps head sleeve are made of soft materials.

The special dental forceps for the intended replantation is further characterized in that the side wall of one end, relatively close to the first finger sleeve part, of the first forceps body is provided with the locking part, and the side wall of one end, relatively close to the second finger sleeve part, of the second forceps body is provided with the locking tooth part which is matched with the locking part and used for locking the forceps bodies.

The dental forceps for intentional replantation further has the characteristic that the first forceps head sleeve and the second forceps head sleeve are made of sponge rubber.

The beneficial effect of above-mentioned scheme is:

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be further described with reference to the following specific examples, which should not be construed as limiting the invention.

Fig. 1 is a schematic structural view of a special dental forceps provided in an embodiment of the present invention. As shown in fig. 1, the special dental forceps provided in the embodiment of the present invention includes: first pincers body 1, the second pincers body 2, first binding clip 6 and second binding clip 7, the utility model discloses in be equipped with first finger cover portion 3 on the first pincers body 1, and be equipped with second finger cover portion 4 on the second pincers body 2, the middle part of the first pincers body 1 is through round pin axle 5 and the 2 pin joints of the second pincers body, the utility model discloses in the longitudinal section of first pincers head 6 and second binding clip 7 all be the arc threadiness, and the bottom of first pincers head 6 and second binding clip 7 is connected on first pincers body 1 and second pincers body 2 one-to-one respectively.

Oral anatomy shows that there is an outline high point on the facial-lingual side of a general molar crown, that is, there is a spherical protrusion on each facial-lingual side of the crown (such spherical protrusion is generally 1/3 or at the neck 1/3 in a clinical crown), and in view of this, the present application sets an arc-shaped forceps head to make the forceps head perfectly fit on the outline high point on the facial-lingual side of the crown by utilizing the concave and convex matching of the forceps head and the crown, so as to achieve the effect of effectively clamping and fixing teeth.
