Technical Field

The invention relates to oral cavity detection equipment, in particular to a wireless oral cavity digital X-ray detector.

Background

The digital X-ray detector in the oral cavity adopts a specific photoelectric conversion medium to convert an X-ray signal passing through a human body into a digital signal, and an imaging system generally comprises an image transmission system, a processing system and a display system. Are typically mounted on or associated with diagnostic X-ray machines for converting X-ray signals into digital signals. At present, the digital X-ray detector in the oral cavity is widely applied to discovering hidden tooth structures, malignant or benign lumps, bone loss, decayed teeth, dental pulp diseases and the like in oral cavity clinical treatment.

The common oral digital X-ray detector mainly has two modes of a wired mode and a wireless mode, the wired communication mode is limited by a transmission wire, the use is inconvenient, and the storage occupies space, so that the oral digital X-ray detector in the wireless transmission mode is more and more widely used.

In order to solve the above technical problem, the present invention provides a wireless intra-oral digital X-ray detector, which comprises a detector plate for receiving X-ray signals and a signal processing unit, and is characterized in that: the detector flat plate is electrically connected with the signal processing unit through a flexible connecting wire, the detector flat plate is arranged on the detector flat plate support, the bottom of the detector flat plate support is movably matched with one end of a connecting rod, the other end of the connecting rod is fixedly connected with the signal processing unit support, and the signal processing unit is arranged in the signal processing unit support.

Preferably, the connecting rod is a telescopic rod capable of axially stretching.

In a further preferred scheme, the center of the bottom of the flat detector support is provided with a ball head extending outwards, and the end part of the connecting rod is arranged in a spherical groove movably matched with the ball head in a tight fit manner.

Further preferably, a notch suitable for inserting the ball head into the spherical groove is formed in one side of the spherical groove at the end of the connecting rod.

Further preferably, the flexible connecting wire is a flexible connecting wire or a spring connecting wire.

Optionally, the bottom of the detector flat plate support 6 is hinged to one end of the connecting rod 7, or magnetically connected through a strong magnet.

The invention has the beneficial effects that: (1) in the detector fixing frame, the bottom of the detector flat plate bracket is movably matched with one end of the connecting rod, and the other end of the connecting rod is fixedly connected with the signal processing unit bracket, so that the multi-angle and length adjustment of the detector flat plate is realized, the image shooting of different tooth positions is facilitated, the use of medical personnel is facilitated, and the comfort level of a patient is improved. (2) The detector flat plate and the wireless signal processing unit are connected by adopting a flexible connecting wire, so that a user can conveniently place and adjust the detector flat plate. (3) When the detector works, a detector flat plate of the wireless oral digital X-ray detector is fixed on a detector fixing frame, and then the detector fixing frame is stretched into an oral designated position to wait for X-ray irradiation. As shown in fig. 3-6, the wireless intra-oral digital X-ray detector is composed of a detector plate, a wireless signal processing unit and a flexible connecting line, so that the detector plate is not limited by the wireless signal processing unit, and a user can conveniently place and adjust the detector plate; the detector mount comprises detector plate holder, wireless signal processing unit support and connecting rod, and the design has the cardan shaft between detection plate holder and the connecting rod, can realize level and vertical two kinds of states, satisfies the shooting of the image of different tooth positions.
