Description
Technical field
The utility model relates to a kind of two-layered, formed clamp devices, belong to the field of medical instrument technology.
Background technique
Generallyd use when oral medicine repair teeth at present tooth matrix band for be used as artificial vacation wall, be filled material
Pressurization, prevent on the nigh tooth of packing material adhesion.Tweezers are generallyd use when in use by the molding on matrix holder
Piece is placed on tooth to be filled, matrix band it is convex one towards gum side, and edge should be in the root side of hole gum wall.It is using
When, it usually needs matrix band is put well with hand-held tweezers, when patient is that child or mouth cannot open very big patient
Say, matrix band is suitably positioned it is extremely difficult, and the matrix band of tooth side monolithic filler material pressurize when can be to another
The tooth of one end causes certain adhesion, influences the aesthetics of tooth.
Summary of the invention
Purpose of the utility model is to solve the above problem, provide that a kind of structure is simple, bilayer compact to design
Matrix holder device.
The utility model adopts the following technical solution: a kind of two-layered, formed clamp device, including telescopic rod, adjusting rod and point
Dental assembly, described that dental assembly is divided to include front opening and symmetrically arranged two linking arms, the centre of the linking arm is provided with
Linkage section, is provided with slide bar on the linkage section, and the upper end of the slide bar is provided with briquetting after linkage section, on the briquetting
It is connected with adjusting rod, the bottom of described two linking arms is hinged with a point tooth piece, and the bottom symmetrical for being divided to tooth piece is provided with two groups
Inserted sheet, it is described that tooth on piece is divided to be provided with telescopic rod.
Further, the telescopic rod includes the first round bar and the second round bar, and second round bar is cavity structure, described
First round bar is socketed on the second round bar, and first round bar can be moved along the cavity of the second round bar.
Further, the inserted sheet is inclined at a point tooth on piece, and the front position of the inserted sheet is higher than inserted sheet rear end position
It sets.
Further, described that tooth on piece is divided to be provided with tension spring.
The utility model structure is simple, compact to design, easy to use, can be realized by adjusting rod and slide bar to dividing tooth piece
Clamping, can the gap of tooth rear and front end be separated for respectively in tooth rear and front end while place matrix band, subtracted
Operating procedure is lacked.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference: telescopic rod 1, adjusting rod 2 divide dental assembly 3, linking arm 3-1, linkage section 3-2, slide bar 3-3, briquetting 3-
4, divide tooth piece 3-5, inserted sheet 4, tension spring 5.
Specific embodiment
Below in conjunction with attached drawing, the utility model will be further described.
As shown in Figure 1, a kind of two-layered, formed clamp device, including telescopic rod 1, adjusting rod 2 and divide dental assembly 3, divides tooth group
Part 3 includes front opening and symmetrically arranged two linking arm 3-1, the centre of linking arm 3-1 are provided with linkage section 3-2, is connected
Slide bar 3-3 is provided on section 3-2, the upper end of slide bar 3-3 is provided with briquetting 3-4 after linkage section 3-2, connects on briquetting 3-4
There is adjusting rod 2, the bottom of two linking arm 3-1 is hinged with a point tooth piece 3-5, is divided to the bottom symmetrical of tooth piece 3-5 to be provided with two groups and inserts
Piece 4, telescopic rod 1 include the first round bar and the second round bar, and the second round bar is cavity structure, and the first round bar is socketed in the second round bar
On, the first round bar can be moved along the cavity of the second round bar, and inserted sheet 4 is inclined on point tooth piece 3-5, the front end position of inserted sheet 4
It sets and is higher than 4 back-end location of inserted sheet, divide on tooth piece 3-5 and be provided with telescopic rod 1, divide on tooth piece 3-5 and be provided with tension spring 5.
Application method: the length of telescopic rod 1 is adjusted, dental assembly 3 will be divided to protrude into oral cavity and be placed on tooth to be repaired
Side, adjusting rod push, adjusting rod 2 drive briquetting will divide under the drive of linking arm 3-1 downwards along slide bar 3-3 tooth piece 3-5 to
It is clamped on tooth to be repaired, the inserted sheet of the bottom tooth piece 3-5 is divided to be inserted between tooth and front and back tooth respectively, and distinguish inserted sheet 4
Contacted with the relative inner of tooth, make the gap enlargement between tooth to be repaired and front and back tooth, be matrix band placement process more
It is unobstructed, and can be realized while quickly placing front and back matrix band, guarantee not interfering with other teeth when repair teeth, uses knot
Adjusting rod is lifted up after beam, briquetting 3-4, which unclamps to drive, divides tooth piece 3-5 and tooth to separate, and tooth piece 3- is divided under the drive of tension spring 5
5 be in closure trend, divides dental assembly 3 by the taking-up of telescopic rod 1.
