Abstract
The present invention discloses a fixed measuring clamp for an oral photographing dental film, which comprises a head part and a handle connected with the head part, wherein the head part is composed of a clamping part of a dental film and a biting positioning part. The present invention is characterized in that the clamping part of a dental film is a bending board approximating to a rectangle, both ends of the clamping part have downward flanging edges for clamping the dental film, the biting positioning part at the back side of the clamping part is provided with a lug boss connected with the clamping part, and round metal ball for measurement is arranged in the lug boss. The present invention has the advantages of simple structure, convenient use, accuracy for fixing and positioning, and high measuring precision.
Description
Technical field
The present invention relates to a kind of tooth sheet fixation measuring clamp that carries out the photography of tooth sheet for the oral cavity patient.
Background technology
According to domestic and foreign literature is retrieved, present Buccodental is taken the photograph sheet and is all adopted the doctor to place the tooth sheet merely, indicates patient with pointing fixedly tooth sheet method then, finishes the photography of tooth sheet.There is following drawback in this method: the one, be difficult to guarantee oral hygiene, cause cross infection easily, because of a photography doctor often will be multidigit oral cavity patient service, even the operation doctor notes the hand disinfection cleaning again, but the work characteristics that is limited to the oral photographing technology, in practical operation, also be difficult to guarantee not antibacterial, virus in external environment or certain the patient oral cavity are brought in another one patient's the oral cavity, thereby make it suffer the infection of virus spread.It two is to go in the disease population fixedly tooth sheet of indication with finger, and patient's foreign body sensation is strong, brings miseries such as vomiting reaction to patient, and patient is difficult to accept, and might cause photography to fail.Its three be camera angle only with the operation doctor experience and patient's dental growth situation estimate, the tooth sheet easily is shifted in the oral cavity, causes camera angle to be difficult to guarantee accurately, causes tooth sheet image distortion easily, measure to odontopathy diagnosis, tooth pulp canal, bring very big difficulty.How overcoming above-mentioned defective, then is urgent problem.
Summary of the invention
It is painful big to the objective of the invention is the tooth sheet photographic process patient that exists at prior art, and cross infection easily takes place, and photography easily causes the problem of image distortion, provides a kind of oral photographing dental film of locating tooth sheet and energy measurement tooth sono-explorer to measure folder.
The present invention realizes with following technical scheme: a kind of fixation measuring clamp for oral photographing dental film, it comprise by dental film holder hold portion and tooth sting the head formed the location division and and the handle of head disjunctor, it is characterized in that the dental film holder portion of holding one is similar to rectangular twisted plate, downward flanging clamping tooth sheet is arranged at its two ends, the tooth at the back side of clamping part sting the location division be one with the boss of clamping part disjunctor; In boss, be equipped with to measure and use the metal ball.
X-ray tooth sheet is inserted in the flanging of clamping part during use, Yi Bian expose slightly or concordant with clamping part, another side exposes; According to quilt photography tooth, gripping handle to be the center by clapping tooth, is put into patient's mouth, and allowing the patient bite positioning boss can make film.Make dip stick can convert easily tooth pulp canal size and tooth size with Metal Ball.
Good effect of the present invention is: simple in structure, easy to use, the hand-held handle of patient can be put into the tram in oral cavity, need not the doctor with the indication of hands inlet, if make disposable product, and clean hygiene, location survey is accurate.
Description of drawings
Describe the present invention below in conjunction with drawings and Examples.
Fig. 1 is an axonometric chart of the present invention;
Fig. 2 is a front view of the present invention;
Fig. 3 is a vertical view of the present invention.
Among the figure: 1, dental film holder is held portion, and 2, handle, 3, a tooth boss of insisting, 4, flanging, 5, the metal ball.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, dental film holder is held portion 1 and one is similar to rectangular twisted plate, and its crooked radian is close with the human teeth position, and there is downward flanging 4 at its two ends, the gap l of flanging 4
2Being slightly larger than tooth sheet thickness does not come off inserting the tooth sheet easily and is advisable.Spacing l between the flanging of two ends
1Be slightly larger than the tooth leaf length.L in the present embodiment
1Be 41.99mm, l
2Be 1.3mm.If being used for the child can be with l
1Length is dwindled.The back side that dental film holder is held portion 1 has one to supply tooth to sting localized boss 3.An insist boss 3 of tooth is combined as a whole with handle 2.The similar serpentine of the shape of handle 2 is beneficial to the patient like this and grips, and in the oral cavity fixing-stable.One metal ball is housed in boss 3, is beneficial to converse tooth pulp canal size and tooth size.Why selecting ball to make surveyors' staff, is because spherical shape can not influence because of taking the photograph the variation of sheet orientation, is shown as circle on film all the time.The diameter of metal ball is a fixed dimension, so just can be on film be object of reference with the diameter of a circle, the size of converting out root canal length and tooth in proportion.
This tooth sheet fixation measuring clamp can adopt injection moulding process, uses the non-toxic plastic injection mo(u)lding.
Claims (4)
1. fixation measuring clamp for oral photographing dental film, it comprise by dental film holder hold portion and tooth sting the head formed the location division and and the handle of head disjunctor, the dental film holder portion of holding one is similar to rectangular twisted plate, at its two ends downward flanging clamping tooth sheet is arranged, it is characterized in that the tooth at the back side of clamping part sting the location division be one with the boss of clamping part disjunctor; In boss, be equipped with to measure and use the metal ball.
2. a kind of fixation measuring clamp for oral photographing dental film according to claim 1 is characterized in that the length l 1 of flat cuboid clamping part is slightly larger than X-ray tooth leaf length, and its crooked radian and human body dental bed flexibility are approximate.
