Description

Fixing frame for oral cavity X-ray photography imaging

Technical Field

The utility model relates to the field of medical instruments, in particular to a fixing frame for oral cavity X-ray photography imaging.

Background

With the development of modern medical procedures, oral radiography is an indispensable part of dental disease diagnosis, and thus an oral radiologist or technician is charged with a large number of oral apex film shots every day.

Because the individual tooth specificity of the patient is different, and the tolerance of the patient to the image plate is not high, the pharyngeal reflex is easy to appear during shooting, so that the image plate deviates from the tooth position of the patient, the error rate of shooting is increased, the image quality of the dental film is reduced, and the finger of the patient presses the image plate in the traditional shooting mode, so that the sanitation potential safety hazard is increased.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide the fixing frame for the X-ray photography imaging of the oral cavity, which increases the success rate of shooting and the image quality, improves the comfort level of examination of a patient, improves the working efficiency of a doctor and reduces the waiting time of the patient for examination.

The purpose of the utility model can be realized by the following technical scheme:

a fixture for oral radiography imaging, the fixture comprising:

the image plate clamping plate is used for clamping an image plate for X-ray photography imaging;

the back splint is used for matching with the image plate splint to clamp teeth;

the connecting plate is used for elastically connecting the image plate clamping plate with the back clamping plate;

the space between the image plate clamping plate and the back clamping plate is matched with the thickness of the teeth, and the image plate clamping plate is positioned on one side close to X-ray shooting.

The connecting plate, the left image plate clamping plate, the right image plate clamping plate and the back clamping plate form movable U-shaped clamps, the image IP plate is placed in the image plate clamping plates and clamped at the positions of the teeth of patients, and the U-shaped clamps are tightly attached to the gums of the patients to wrap the teeth of the patients to be fixed for projection shooting.

Further, the fixing frame also comprises a handle which is convenient to hold, and the handle is detachably connected with the connecting plate.

Furthermore, the handle is provided with a small switch for controlling the distance between the image plate clamping plate and the back clamping plate.

It is not difficult to imagine that, because the image plate clamping plate and the back clamping plate have the clamping function of bending inwards, the small switch has the function of slightly pulling the distance between the image plate clamping plate and the back clamping plate between the clamping teeth, so that the clamping is convenient, and the mechanism is the prior art and can be seen everywhere in the market.

Furthermore, one side of the handle, which is far away from the connecting plate, is provided with a tongue depressor structure. The tongue depressor structure can check the specific condition of teeth in the oral cavity before shooting, fully utilizes the space of the fixing frame and realizes function integration.

Further, the edges of the image plate clamping plate and/or the back clamping plate are subjected to rounding processing. Avoiding the damage of the edge of the fixing frame to the gum.

Furthermore, the fixing frame is made of high-temperature-resistant plastic. Is convenient for high-temperature disinfection after use.

Furthermore, the image plate clamping plate is provided with a semicircular groove which is convenient for the image plate to be inserted or taken out.

Furthermore, the distance between the image plate clamping plate and the back clamping plate is matched with the thickness of the large teeth, and the handle is connected with the side of the connecting plate.

Furthermore, a plurality of anti-skid grains are carved on the connecting plate.

When big teeth are shot, an operator can adjust the handle to enable the U-shaped clamp to be tightly attached to the gum of a patient to wrap the affected teeth for fixing, so that the big teeth of the patient can bite the connecting plate with the anti-slip grains above or below for secondary fixing, and then shooting is conducted.

Furthermore, the distance between the image plate clamping plate and the back clamping plate is matched with the thickness of the incisors, and the handle is connected with the back of the connecting plate.

Because the incisors do not have occlusal surfaces, the projection shooting can be carried out without secondary fixation, and sometimes, even the handle can be omitted.

Compared with the prior art, the utility model has the following advantages:

(1) according to the utility model, the connecting plate and the left and right clamping plates form the movable U-shaped clamp, the movable U-shaped clamp is clamped at the teeth of a patient, the U-shaped clamp is tightly attached to the gum of the patient to wrap the teeth of the patient for fixing, projection shooting is carried out, the shooting success rate and the image quality are increased, the examination comfort of the patient is improved, the working efficiency of a doctor is improved, and the waiting time of the patient for examination is shortened;

(2) in the utility model, the mounting position of the handle and the size structure of the connecting plate are flexibly adjusted for the teeth with the large teeth and the incisors and different sizes, so that the fixing frame has stronger applicability and flexibility;

(3) in the utility model, small structures such as a small switch, a tongue depressor, a fillet, a semicircular groove and the like are also creatively arranged, so that the function of the fixing frame is further enhanced, the damage to human tissues is reduced, and the use is more convenient.
