Description

Plug-in type carrying body

Technical Field

The utility model belongs to the technical field of dental implant, in particular to a plug-in carrying body.

Background

The implant carrier is an auxiliary tool for implanting and packaging dental implants, and the following two types of current technical background exist:

(1) the implant carrier and the dental implant are in embedded anti-rotation internal connection, and the carrier and the dental implant are tightly connected together through a carrier screw. The implant carrier with the design has two functions, wherein the first function is to ensure that the dental implant is not contacted with any packaging material when the dental implant is packaged; the second function is to act as a wrench tool during the clinical surgical implantation of the implant.

(2) The implant carrier does not exist, the dental implant is directly placed into the titanium cylinder during packaging, and the dental implant is directly inserted into the titanium cylinder in an interference fit manner by adopting a nail holder tool in the surgical tool box during implantation to perform clinical surgery.

The current technical disadvantages are the following two:

(1) the implant carrier and the dental implant are in embedded anti-rotation internal connection, and the carrier and the dental implant are tightly connected together through a carrier screw. There are three disadvantages to this design: the first is that the packing efficiency is low during production, and a special torque wrench needs to be used for screwing at a fixed value; the second is that the operation is troublesome in clinical operation, after the implantation operation is finished, two wrenches are needed to assist in loosening screws of the carrying body, and then the carrying body is taken out, so that the oral cavity operation space is limited, and the operation in the posterior dental area is more inconvenient; thirdly, if the experience of the clinician is insufficient, the operation force is possibly too large in the clinical operation, which may cause the twist-off phenomenon of the implant carrier; if the implant carrier is twisted off, the product is very small, and certain difficulty exists in clinical taking out.

(2) The implant carrier does not exist, the dental implant is directly placed into the titanium cylinder during packaging, and the dental implant is directly inserted into the titanium cylinder in an interference fit manner by adopting a nail holder tool in the surgical tool box during implantation to perform clinical surgery. There are two disadvantages to this design: the first is that the implant contacts with a packaging material during production and packaging, and certain friction and collision exist in the transportation of a packaging box, so that slight damage is generated on the surface of the implant. The second is to use the interference fit of the nail holder tool in the surgical tool box to insert the dental implant for clinical operation, although the twisting-off phenomenon of the tool can not be generated when implanting the dental implant, if the experience of the clinician is insufficient, the force is too large when implanting, the micro-deformation damage can be caused to the internal structure of the dental implant, the repair of the upper structure can not be carried out in the later stage due to the product with serious deformation, and the dental implant needs to be taken out and a new implant is implanted again.

Disclosure of Invention

In view of this, the present invention provides a plug-in carrying body, which can solve the above problems.

In order to achieve the above purpose, the technical scheme of the utility model is realized like this:

a plug-in type carrying body comprises a body, wherein the body is connected in a dental implant in a plug-in mode, the body sequentially comprises a rotating cap, a clamping groove, a self-breaking groove, a rotating sleeve and an elastic plug from top to bottom, an elastic clamping ring is sleeved at the clamping groove, and the elastic plug is fixedly clamped with a slot of the dental implant.

Furthermore, the elastic plug comprises two elastic shifting pieces which are symmetrically arranged, an elastic groove is formed between the two elastic shifting pieces, and the width of the lower end of each elastic shifting piece is larger than that of the upper end of each elastic shifting piece.

Furthermore, the screw cap and the screw sleeve are all in an octagonal structure.

Further, the torque limit of the self-breaking groove is 70 Ncm.

Compared with the prior art, the plug-in carrying body have following advantage: the retaining screw in the original implant carrier is removed, the elastic interference fit plug-in carrier is changed, and the torque force self-breaking groove is added on the structure of the plug-in carrier. The product structural design solves the defects of low production and packaging efficiency, deformation of the internal structure of the dental implant caused by overlarge torsion, or the unscrewing of the connecting part of the carrying body and inconvenient clinical operation.

The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-8, a plug-in type carrying body comprises a body which is of a solid structure integrally and is connected in a plug-in manner in a dental implant 7, the body comprises a screw cap 1, a clamping groove 2, a self-breaking groove 3, a screw sleeve 4 and an elastic plug 5 from top to bottom in sequence, an elastic clamping ring 6 is sleeved at the clamping groove 2, and the elastic plug 5 is clamped and fixed with a slot of the dental implant 7.

The elastic plug 5 comprises two elastic shifting pieces 51 which are symmetrically arranged, an elastic groove 52 is formed between the two elastic shifting pieces 51, and the width of the lower end of each elastic shifting piece 51 is larger than that of the upper end of each elastic shifting piece.

The screw cap 1 and the screw sleeve 4 are all in an octagonal structure. The design is to directly transfer the eight-direction structure of the screw head of the previous carrier to the head of the plug-in carrier, and the implant wrench used in clinic is matched with the implant screwed into the eight directions of the part for implantation.

Designing a self-breaking groove: according to the torque test of the dental implant (square interface), when the torque reaches 75-80Ncm, the square interface in the dental implant starts to deform slightly, and the critical value of the torque of the dental implant is combined to design that the square interface can be automatically twisted off at the position of the self-breaking groove 3 when the torque reaches 70 Ncm. This design has both protected the internal connection structure of dental implant 7, has also solved the difficulty that current implant moment of torsion is too big twist-off to be difficult to take out.

Design of the elastic plug: this design replaces the carrier screw fixation but relies on the elastic force of the elastic socket 52 to be interference fit to the dental implant 7; since the screw-retaining connection is eliminated, the entire body of the pluggable carrier is of solid design, and twisting can only occur in the region of the self-breaking groove 3, which is also the original design.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
