Description

Disposable biting wing device for shooting biting wing pieces by parallel projection technology

Technical Field

The utility model belongs to the field of medical equipment, especially, relate to a once only sting wing device of wing piece is stung in shooting.

Background

The biting wing is an image technology commonly used in oral diagnosis, and can simultaneously display the pathological changes of the crown part of the partial upper and lower jaw dentition and the crest condition of the alveolar ridge. The biting fins have important value for diagnosing the conditions of adjacent caries, caries depth, pulp cavity shape and alveolar ridge crest absorption, and have the advantages of better shooting comfort, more tooth positions and smaller radiation dose. According to the 'whole population and whole-period oral health management optimization action' proposed by the national Weijian Commission, the biting wings are very suitable for regular monitoring of oral health, and are especially suitable for the population with higher caries risk, stronger radiation sensitivity and lower degree of matching, such as children, teenagers and the like.

The current commonly used shooting method is a simple fin method or a fin-biting and frame-holding method. The simple wing method uses a paper tape to surround the dental film, two ends of the paper tape are pasted into wings on the photosensitive surface of the dental film, and the adjusting wings are vertical to the photosensitive surface and are on the central axis of the dental film; or a rubber ring is sleeved on the central axis of the dental film, a hard paper sheet is taken to be hooked around the rubber ring to be folded into a wing, and the adjusting wing is vertical to the photosensitive surface. The checking mode has low cost and can ensure that the biting wings and the tooth film are vertical theoretically. However, in actual operation, saliva exists in the oral cavity, the paper material is easy to deform and damage, meanwhile, due to the existence of the hard palate and the tongue body, the dental film can incline when being placed in the oral cavity, the angle between the biting wing and the dental film is easy to change, when a patient bites the upper and lower teeth, the technical difficulty of confirming the position and the projection angle of the dental film is high, and distortion and deformation are easy to occur. The other method for holding the tooth sheet by the biting wing sheet uses the rigid holding frame to hold the tooth sheet, and the biting wing which is perpendicular to the tooth sheet and is fixedly connected is arranged on the holding frame, so that the angle deformation can be reduced, the use comfort is poor, and the material consumption and the disinfection cost can be increased to a greater degree.

In the projection mode of shooting biting fins, the angle of the bulb tube needs to be properly adjusted according to the arrangement position, and meanwhile, the teeth can be inclined due to the movement of the tongue body, and the factors can increase the shooting technical difficulty. Part of the film holding frame increases a ball tube ring structure based on the parallel projection principle to reduce the difficulty of the shooting technology, but the manufacturing cost is increased. In addition, most of the bulb tubes of the parallel projection support are contacted with the bulb tubes but are not fixed, so that the bulb tubes are easy to move when being placed, and the imaging quality is influenced. The expanded application of the bite wing is poor due to the lack of the method.
