Description
Technical field
The utility model is related to a kind of department of stomatology apparatus, more particularly to a kind of gutta-percha point measurement cut-out chi.
Background technology
In root canal, according to the length of patient's root pipe, the gutta-percha point of corresponding size is taken, unwanted part is blocked,
Then root canal deviation is carried out.The charge less of root pipe or it is super fill, can all influence root canal.During charge less, periapical tissue's liquid, diffusate
Can bleed back to unfilled pipe, decomposition, the breeding of exudate cause to infect again and root canal failure.It is super when filling, can will be carefully
The infectious agents such as bacterium promote apical foramen of tooth, cause periapex inflammation, in addition, root canal filling material can also cause foreign body reaction in periapical tissue
Or produce toxicity stimulation.Thereby it is ensured that the length and taper of gutta-percha point are extremely important.The standard just filled is the main point of gutta-percha point
End is away from physiological apical foramen error ± 0.5mm.
Method for cutting common at present is scissors excision and blade excision.Need two nurse's quotas complete when scissors is cut off
Into a nurse takes two tweezers to clamp the two ends of gutta-percha point, is directed at hindsight, and another nurse cuts off excess portion by scissors
Point.Different from length in terms of different orientation when being compared due to gutta-percha point from ruler, out of plumb observation easily causes error, this
Outside, the easy hand shaking of nurse, also easily further produces error.Blade excision is similar to scissors excision, simply changes scissors into knife
Piece, it is also desirable to which two people complete, and error is larger.
This two methods also have a defect to be, easily press from both sides flat by gutta-percha point during cut-out gutta-percha point or flatten so that gutta-percha
Sharp taper deformation, it is impossible to coincide with Configuration, further cause filling problem.
Utility model content
In view of the above problems, the utility model is directed to a kind of to collect measurement and be exclusively used in integral with cutting function
The instrument of gutta-percha point so that one can just complete to block work.Farthest ensure to cut in addition, the utility model is also aimed to
The gutta-percha point measurement cut-out chi that gutta-percha tip is deformed during disconnected.
Gutta-percha point measurement cut-out chi of the present utility model, it includes：Base, vernier device；

Between bar, the second guiding bar, and it is parallel with the described first guiding bar, the second guiding bar；Side stage formation is on the right side of base, on side stage
Depressed part is formed with, the left end of depressed part is connected with the right-hand member of U-type groove；
Base leading flank top is provided with graduation mark；
Vernier device includes sliding block, cutting knife component；
Cutting knife component is included by presenting a theatrical performance as the last item on a programme, knife bar, cutter head；Be formed as flat by presenting a theatrical performance as the last item on a programme；Knife bar is formed as cylindricality, its upper end
Fixed to by the downside presented a theatrical performance as the last item on a programme, its lower end is fixed to the upper end of cutter head；Cutter head is formed as flake, itself and U-type groove, the first guiding
Bar, the second guiding bar are vertical, and cutter head lower end is formed as arc shaped, and the camber line with U-type groove is corresponding；
Sliding block is formed as transparent mesa-shaped, and it includes the first bullport, the second bullport, knife bar bullport, cutter head holding tank；
First bullport, the second bullport are respectively formed at the front and rear of sliding block, the first bullport, the second guiding in parallel with each other
Sliding block is run through in hole in the lateral direction, and the first bullport is slideably enclosed on the first guiding bar, and the second bullport is slideably
It is enclosed on the second guiding bar；Knife bar bullport is located in the middle part of sliding block, is formed from top to bottom, and draws positioned at the first bullport, second
Between guide hole；Knife bar bullport is used to accommodate knife bar, and its shape of cross section is corresponding with the shape of cross section of knife bar, and knife bar is by under
Can slide downward in knife bar receiving hole during pressure；Cutter head holding tank is located at below knife bar bullport and connected with knife bar bullport
It is logical, for accommodating cutter head；
Spring is supported by sliding block upper surface and by between lower surface of presenting a theatrical performance as the last item on a programme, is resetted for cutting knife component；
The front side of sliding block includes reclinate pointer, points to the graduation mark on base leading flank top.
Preferably, the cross section of the knife bar is rectangle.
Preferably, the cross section of the knife bar is ellipse.
Preferably, the bottom surface of the depressed part is less than the bottom surface of the U-type groove.
Due to gutta-percha point of the present utility model measurement cut-out chi, by the way that by cutting knife design, on vernier, collection is measured and cut-out
In one, determined first by vernier and scale behind the part to be blocked, pressing cutting knife component completes to block.Further, since this
The U-type groove of the gutta-percha point measurement cut-out chi of utility model has lower arcuate surface, and the contact area with gutta-percha point is larger, effectively prevents
Gutta-percha point taper deformation in truncated process.
