Description
Technical field
It is the utility model relates to oral cavity medical apparatus technical field, in particular to a kind of for clamping the device of corona set.
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 for clamping the device of corona set, to be reduced or avoided
The problem of being formerly mentioned.
In order to solve the above technical problems, the utility model proposes a kind of for clamping the device of corona set comprising hold
The first locating rod being fixedly connected with the handle, the first positioning boom end is provided with the first clamping tooth, the handle
Slidable connection has first motion bar parallel with first locating rod, first motion bar and the first clamping tooth phase
Pair one end be provided with the second clamping tooth, the other end of first motion bar is provided with the cylindrical end for pressing, institute
State the first clamping tooth section be it is trapezoidal, the length on the bottom edge of first clamping tooth is set as 2-6mm, is highly set as 6-
8mm。
Preferably, first locating rod is provided with the leading truck of one with the first motion bar slidable connection.
Preferably, the cylindrical end is connected through a screw thread with first motion bar.
A kind of device covered for clamping corona provided by the utility model, structure is simple, and easy to operate, clamping is steady
It is fixed, substantially increase the working efficiency that doctor removes 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 former according to a kind of structure for clamping the device of corona set of a specific embodiment of the utility model
Manage schematic diagram；
The schematic perspective view for the device for clamping corona set that Fig. 2 is Fig. 1；
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 former according to a kind of structure for clamping the device of corona set of a specific embodiment of the utility model
Manage schematic diagram；The schematic perspective view for the device for clamping corona set that Fig. 2 is Fig. 1.Referring to shown in Fig. 1-2, this is practical
It is novel to provide a kind of device covered for clamping corona comprising handle 1, the first positioning being fixedly connected with the handle 1
Bar 2,2 end of the first locating rod are provided with the first clamping tooth 21, and 1 slidable connection of handle has and first positioning
The first parallel motion bar 3 of bar 2, first motion bar 3 one end opposite with first clamping tooth 21 is provided with the second folder
Tooth 31 is held, the other end of first motion bar 3 is provided with the cylindrical end 32 for pressing.
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, later can by cylinder end 32 described in thumb press,
To push first motion bar 3 to make the outer side contacts of second clamping tooth 31 with temporary dental crown set.It can thus press from both sides
Tight temporary dental crown set, can easily temporary dental crown set be removed by then shaking the device for clamping corona set.
The cylinder end 32 can be to be connected through a screw thread with first motion bar 3, is convenient for producing in this way
The assembly of first motion bar 3 and the handle 1 described in journey.Certainly, the cylindrical end 32 is also possible to and described first
3 grafting of motion bar (for example, the cylinder end 32 is provided with jack, first motion bar 3 is provided with corresponding plug).
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.
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 2-6mm, height H may be configured as 6-8mm, can avoid causing tooth ontology in this way in clamping process
Damage, and can ensure structural strength.
A kind of device covered for clamping corona provided by the utility model, structure is simple, and easy to operate, clamping is steady
It is fixed, substantially increase the working efficiency that doctor removes temporary dental crown.
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
