Abstract

The utility model provides a dental X-ray film fixing grip, consisting of a negative grip block and a handle. The dental X-ray film fixing grip is characterized in that the grip block whose area sizes scope is 0.20-0.40 of the grip negative area sizes consists of a front and a back plate, and a clamping seam is positioned between the front plate and the back plate. Compared with the current techniques, the utility model has the advantages and the active effects that the area of the grip block improved to be in a grip shape and in a triangle is only 0.20-0.40 of the negative area, therefore, largely reducing the area of the grip block. Thus, the fixing grip can be adjusted flexibly into the mouth of the patient, and the patient does not need to open the mouth over size, relieving the malaise of the patient.

Description

The oral photographing dental film fixation clamp

Technical field

This utility model relates to a kind of for the oral cavity patient carries out the tooth sheet fixation clamp that the tooth sheet is photographed, and is the improvement to existing tooth sheet fixed folder structure.

Background technology

According to domestic and foreign literature retrieval as can be known, Buccodental is taken the photograph sheet and is all adopted the doctor to place the tooth sheet merely at present, indicate then patient with finger fixedly tooth sheet method finish the tooth sheet and photograph.There is following drawback through this method of practice test: one, be difficult to guarantee oral hygiene, cause cross infection easily, position, oral cavity saliva is the source of infection of multiple infectious disease often, as hepatitis B virus, the TB bacillus, influenza virus, ADIS virus etc., and a photography doctor often just is not an oral cavity patient service, but to face the multidigit patient, 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 the antibacterial in external environment or certain the patient oral cavity, virus is brought in another one patient's the oral cavity, thereby makes it suffer the infection of virus spread.Two, go into to indicate fixedly tooth sheet in the disease population with finger, patient's foreign body sensation is strong, brings miseries such as vomiting reaction to patient, and patient is difficult to accept, and might cause the photography failure.Its three, camera angle is only estimated with operation doctor's experience and patient's dental growth situation, causes camera angle to be difficult to guarantee accurately cause tooth sheet image distortion easily, measures to odontopathy diagnosis, tooth pulp canal, the dental pulp perfusion therapy brings very big difficulty.In order to overcome above-mentioned defective as early as possible, the inventor has developed a kind of tooth sheet fixed mount, the patent No.: 01262113.7, utility model title " oral photographing dental film measurement analog bracket ".The technical scheme of this utility model is: it comprises a vertical plate shaped tooth tablet tray, these tooth tablet tray both sides be provided with clamping tooth sheet to in-flanges, at the tooth tablet tray back side handle is housed.In tooth tablet tray lower end one plate shaped angle mouth guard is installed, this angle mouth guard and tooth tablet tray are installed together versatilely by axle and axle sleeve.This technical scheme makes the patient can hand the tram that handle is put into the oral cavity, and need not the doctor and indicate with the hands inlet, a people one pair, clean hygiene, thus avoided cross infection, prevented the propagation of infectious disease.But this technical scheme is found still to exist not attain to improve part through practice test, have the following disadvantages: 1, the tooth tablet tray is made the square plate shape suitable with egative film, the pallet both sides be clamping tooth sheet to in-flanges, whole pallet volume is bigger, in shooting process, the patient need firmly magnify mouth, effort, do not feel well, some patient has vomiting reaction.2, the flange of clamping tooth sheet is positioned at the both sides of pallet, and crack is onesize from top to bottom, and clamping is not tight, and some positions of egative film are in loosening state, and sometimes, egative film can change by occurrence positions, need readjust, and also can influence shooting effect.

Summary of the invention

This utility model provides a kind of novel oral photographing dental film fixation clamp, and it can solve the bigger problem of bringing of pallet that prior art exists.

Solve the in-problem purpose of prior art in order to reach, the technical solution of the utility model is, a kind of oral photographing dental film fixation clamp, it comprises egative film grip block and handle, it is characterized in that: described grip block comprises forward and backward clamping plate, be the crack of clamping egative film between the forward and backward clamping plate, the area magnitude range of grip block is 0.20～0.40 of a clamping egative film area size.

In this utility model, also have following technical characterictic: described grip block is a triangle, or is subtriangular, or dual-side is dihedral, and the base is a circular arc.

In this utility model, also have following technical characterictic: the crack slit of described grip block is narrowed down by wide to preceding from the back.

In this utility model, also have following technical characterictic: described handle and grip block junction be shaped as C shape.

This utility model compared with prior art has the following advantages and good effect: 1, grip block is improved to the clip shape, and it is triangular in shape, its area only is 0.20～0.40 of an egative film area, thereby reduced the grip block area greatly, in disease population, can place adjustment flexibly, patient need not to open one's mouth excessive, alleviates patient's sense of discomfort.2, grip block is triangular in shape, and crack narrows down by wide to preceding from the back, and it is stable both to be beneficial to clamping, is beneficial to installation again.3, the design of C clamp formula is adopted in the handle junction, and is easy for installation, rotates flexibly.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, grip block 2 comprises forward and backward clamping plate 2-1,2-2, between forward and backward clamping plate 2-1, the 2-2 crack 2-3 of clamping egative film 3, the crack slit of grip block is extremely preceding from the back to be wide narrowing down, forward and backward clamping plate have certain closed and locked effect, help plug-in mounting like this and clamp egative film 3.

In the present embodiment, the area magnitude range of grip block 2 is 0.28 of clamping egative film 3 area sizes.Grip block 2 pictures one triangle, clamping is stable like this.

Described handle and grip block junction be shaped as C shape, easy for installation like this, rotate flexibly.

During use, egative film 3 is inserted from crack 2-3 rear portion, change over to then to whole crack 2-3, hand holding handle bar 1-2 puts into the oral cavity, just can take.

Certainly, this utility model is not limited to above-mentioned giving an example, and in essence intention scope of the present utility model, this utility model also has many variations, remodeling or replacement, all should belong to protection domain of the present utility model.
