Description

A kind of corona set clamper

Technical field

The utility model relates to oral cavity medical apparatus technical field, in particular to a kind of corona covers clamper.

Background technique

Root canal treatment is the most commonly used effective treatment method in the world of dental pulp disease and periapical disease.The tooth of root canal treatment It without dental pulp also just without the ability of absorption nutrient, is easily broken off so tooth is more fragile, therefore usually requires to do tooth Hat is repaired to avoid tooth fracture.

After root canal treatment, since the manufacture of long-term corona set needs a time course, in long-term corona Before set completes, it will usually be protected using temporary dental crown set to tooth.

It is also to be bonded on tooth using adhesive since temporary dental crown covers, needs to make when removing temporary dental crown set Corona is covered with clamping device and is removed.

Existing clamping device is usually to use common Medical forceps, since common Medical forceps are flat construction, Doctor is very inconvenient when clamping temporary dental crown set, and since corona is usually that wall is thin, if clamping is improper, it is easy to cause Injury of teeth.Chinese patent CN205083671U provides a kind of corona gripper clamp, but it still uses flat construction, therefore same Sample there is a problem of inconvenient.

Utility model content

The technical problem to be solved by the present invention is to provide a kind of coronas to cover clamper, is mentioned so that front is reduced or avoided To the problem of.

In order to solve the above technical problems, the utility model proposes a kind of coronas to cover clamper comprising handle, and it is described The first locating rod that handle is fixedly connected, the first positioning boom end are provided with the first clamping tooth, and the handle slidably connects It is connected to cylinder first motion bar parallel with first locating rod, the described first movable boom end is provided with the second clamping Tooth, first motion bar are fixedly connected with the handle parallel with the handle by nut, and second clamping tooth is socket In the rectangular rubber pad of the described first movable boom end.

Preferably, first locating rod is provided with the leading truck of one with the first motion bar slidable connection.

Preferably, it may be provided with compressed spring between the handle and the handle.

Preferably, the section of first clamping tooth is trapezoidal, and the length on the bottom edge of first clamping tooth is 3-6mm, Height is 6-10mm.

A kind of corona provided by the utility model covers clamper, and structure is simple, easy to operate, and clamping is stablized, and mentions significantly High doctor removes the working efficiency of temporary dental crown.

Detailed description of the invention

Following drawings are only intended to schematically illustrate and explain the present invention, does not limit the model of the utility model It encloses.Wherein,

Fig. 1 is that the structural principle for covering clamper according to a kind of corona of a specific embodiment of the utility model is illustrated Figure；

Fig. 2 is that the corona of Fig. 1 covers the schematic perspective view of clamper；

Fig. 3 is the A of the first clamping tooth in Fig. 1 to structural schematic diagram.

Specific embodiment

For a clearer understanding of the technical features, objectives and effects of the utility model, now compareing Detailed description of the invention Specific embodiment of the present utility model.Wherein, identical component uses identical label.

Fig. 1 is that the structural principle for covering clamper according to a kind of corona of a specific embodiment of the utility model is illustrated Figure；Fig. 2 is that the corona of Fig. 1 covers the schematic perspective view of clamper.Referring to shown in Fig. 1-2, the utility model provides one kind Corona covers clamper comprising handle 1, the first locating rod 2 being fixedly connected with the handle 1,2 end of the first locating rod It is provided with the first clamping tooth 21,1 slidable connection of handle has cylinder first activity parallel with first locating rod 2 Bar 3,3 end of the first motion bar are provided with the second clamping tooth 31, and first motion bar 3 is fixedly connected with by nut 33 The handle 32 parallel with the handle 1, second clamping tooth 31 are to be socketed in the rectangular rubber of 3 end of the first motion bar Pad.

When doctor needs to remove the temporary dental crown set of patient, first locating rod 2 first can be protruded into patient oral cavity, made The interior side contacts of first clamping tooth 21 and temporary dental crown set, can press the handle 32, to push away by palm later Moving first motion bar 3 makes the outer side contacts of second clamping tooth 31 with temporary dental crown set.It can thus clamp interim Corona set, can easily temporary dental crown set be removed by then shaking corona set clamper.

First motion bar 3 is fixedly connected with the handle 32 by nut 33, and second clamping tooth 31 is to be socketed in The rectangular rubber pad of first motion bar, 3 end, in this way can be in order in process of production to first motion bar 3 and institute It states handle 1 to be assembled, and can be by replacing different rectangular rubber pads (i.e. described second clamping tooth 31) come easily to not The corresponding corona set of same tooth carries out dismantling operation.

First locating rod 2 is also provided with the leading truck 22 of one with 3 slidable connection of the first motion bar, this Sample can more accurately be oriented to first motion bar 3.

It may be provided with compressed spring 4 between the handle 32 and the handle 1, first motion bar 3 can be convenient in this way It resets.

Fig. 3 is the A of the first clamping tooth in Fig. 1 to structural schematic diagram.Dotted portion indicates first locating rod 2 in Fig. 3 Position, shown in Figure 3, the section of first clamping tooth 21 may be configured as trapezoidal, the bottom edge of first clamping tooth 21 Length L may be configured as 3-6mm, height H may be configured as 6-10mm, can avoid causing tooth ontology in this way in clamping process Damage, and can ensure structural strength.

It will be appreciated by those skilled in the art that although the utility model is described in the way of multiple embodiments , but not each embodiment only contains an independent technical solution.So narration is in specification just for the sake of clear For the sake of, the skilled in the art should refer to the specification as a whole is understood, and by skill involved in each embodiment Art scheme, which is regarded as, can be combined with each other into the modes of different embodiments to understand the protection scope of the utility model.
