Problems solved by technology
However, the anterior teether film fixing device and the rear teether film clamping pliers of the film holder are integrally connected. Bending caused a lot of inconvenience to the operation, and when the clamping claws of the film holder clamped the film, it often caused the film to fall off, and the clamping was not firm enough. In addition, when shooting the front teeth or the back teeth When filming, the teeth need to bite the front teeth film fixing device or the back teeth film clamping forceps, and the surface of the clamping piece of this patent is smooth, which is easy to cause the bite to fall off, which is inconvenient for taking dental films

The invention relates to an X-ray film clamping clip. The X-ray film clamping clip comprises a front-tooth film fixing device and rear-tooth film clamping pincers, wherein the front-tooth film fixingdevice comprises a clamping baffle plate, a clamping piece and a bottom plate, the rear-tooth film clamping pincers comprises a narrow pincers head, a narrow pincers arm, a wide pincers head, a wide pincers arm and a fastening ring, the bottom plate and the narrow pincers arm are connected by a screw and a rivet, the screw is connected with the rivet by a thread, the fastening degree between the bottom plate and the narrow pincers arm can be adjusted by adjusting the connection depth between the screw and the rivet, engagement teeth are arranged on surfaces of the narrow pincers head and the wide pincers head and at the bottom of the clamping baffle plate, one end of the clamping piece is fixedly connected with the bottom plate, and the other end of the clamping piece is turned up in a waydeviating from the clamping baffle plate. The X-ray film clamping clip is high in accuracy, is firm to clamp, is safe and clean, is convenient to hold by a patient and can be used for performing omnibearing radiation on teeth in oral cavity, and engagement and slip are prevented.
Description
technical field [0001] The invention relates to a dental medical appliance, in particular to an X-ray film holder. Background technique [0002] As we all know, the current X-ray dental film photography in the department of stomatology requires hands, tweezers or clumsy clippers to clamp the X-ray dental film into the oral cavity, and then the patient uses both hands to support and fix the film, which is neither convenient nor hygienic. And it is easy to infect other diseases, and it is not easy to ensure the photographic quality of the negatives. [0003] The patent "X-ray dental film holder" with the publication number CN2088707 discloses an X-ray dental film holder, which is composed of an integral connection between the anterior dental film fixing device and the posterior dental film clamping forceps. The clamping baffle, the clamping claw and the bottom plate are composed of the clamping baffle, the clamping claw and the bottom plate. The rear teeth film clamping plier...
