Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and mainly to an oral photography device and a control method thereof. Background Art

[0002] According to the basic requirements of oral diagnosis for X-ray examination, dental diseases should be treated with intraoral films, orthodontics should be treated with panoramic films and cephalographic films, and implants should be treated with CT. The oral and maxillofacial cone beam CT (CBCT for short) currently available on the market can integrate three functions: CT, panoramic films, and cephalography. However, a separate intraoral radiograph is required to complete the intraoral filming work. Oral filming equipment is subject to the provisions of GBZ130: X-ray product equipment must have a separate shielded room. Therefore, users who have both CBCT and intraoral radiographs usually need to establish at least two shielded rooms to meet national standards, which increases the user's infrastructure, procurement, and equipment use costs. In order to reduce the equipment use costs of clinics that have both CBCT and intraoral radiographs, there is a need in this field for an oral filming device that combines CT, panoramic films, cephalography, and intraoral filming functions.

[0034] The interlocking mechanism comprises:

[0035] An electrical switch, comprising a moving contact, a first contact and a second contact; the first contact is connected to the oral camera, and the second contact is connected to the intraoral radiograph; the moving contact is respectively connected to one of the first contact and the second contact, so as to disable one of the oral camera and the intraoral radiograph.

[0042] The technical solution of the present invention has the following advantages:

[0043] 1. The oral photography equipment provided by the present invention comprises: an oral camera for completing CT scanning and / or panoramic film and / or cranial photography; an intraoral radiograph for completing intraoral film photography; an interlocking mechanism comprising: a first controller for controlling the activation or disabling of an action mechanism of the oral camera; a second controller for controlling the activation or disabling of an action mechanism of the intraoral radiograph; a sensor, which is communicatively connected to the first controller and the second controller respectively, and when the radiation generating mechanism and / or action mechanism of one of the oral camera and the intraoral radiograph is in operation, the sensor sends a control signal to the other of the oral camera and the intraoral radiograph, and the action mechanism of the oral camera or the intraoral radiograph that receives the control signal is controlled by the first controller or the second controller to be unable to be activated.

[0044] According to national regulations, oral cameras and intraoral radiographs cannot work at the same time to meet the corresponding safety protection standards. When the intraoral radiograph is using its intraoral film scanning function, the scanning function of the oral camera cannot be started; similarly, when the oral camera is working on CT scanning, panoramic film and cranial photography, the intraoral film scanning function of the intraoral radiograph is not allowed to start working. When the intraoral radiograph and the oral camera work at the same time, it will cause the problem of excessive radiation values, causing radiation safety accidents. In the prior art, the oral camera and the intraoral radiograph are installed in two independent shielded rooms respectively to prevent the problem of excessive radiation values. However, the prior art requires two shielded rooms and separate oral cameras and intraoral radiographs to meet national requirements, which increases the user's costs in infrastructure, procurement, and equipment use. The present invention sets an interlocking mechanism that is respectively connected to the oral camera and the intraoral radiograph. The interlocking mechanism can detect the operating status of the radiation generating mechanism and / or the action mechanism of the oral camera and the intraoral radiograph through a sensor. If the sensor detects that one of the oral camera and the intraoral radiograph is in an operating state, a signal will be sent to the first controller or the second controller. The first controller or the second controller controls the oral camera or the intraoral radiograph to be unable to start. The first controller is used to control the start or disable of the action mechanism of the oral camera; the second controller is used to control the start or disable of the action mechanism of the intraoral radiograph. The interlocking mechanism with the sensor, the first controller and the second controller can control the oral camera and the intraoral radiograph to not work at the same time, and only one of them can be in the working state, so that the oral photography equipment of the present invention can simultaneously integrate at least one of CT, panoramic film, and cranial photography and the function of taking intraoral films. Thereby meeting the national regulations, while solving the problem that the existing oral camera and intraoral radiograph cannot be set together, and solving the problem that the existing oral photography equipment has high construction and use costs.

[0045] 2. The oral photography equipment provided by the present invention, the sensor includes: a first position sensor arranged on the rotating arm of the intraoral radiograph, and a second position sensor arranged on the skull arm and / or skull plate and / or scanner and / or jaw support arm and / or lifting column of the oral camera.

[0046] The above position sensor can effectively sense the operating status of the action mechanisms of the oral camera and the intraoral radiograph, so that the oral photographing device can control the oral camera and the intraoral radiograph according to their working status information so that they cannot work at the same time.

[0047] 3. The oral imaging equipment provided by the present invention, the sensor includes: a radiation-sensing sensor arranged on the radiation-generating mechanism of the intraoral radiograph; and / or a radiation-sensing sensor arranged on the radiation-generating mechanism of the oral camera.

[0048] The above-mentioned two radiation sensing sensors can respectively detect the operating status of the radiation generating mechanisms of the intraoral radiograph and the oral camera, thereby sending the working status of the radiation generating mechanisms to the first controller or the second controller. The first controller and the second controller prevent the oral camera and the intraoral radiograph from working at the same time, thereby ensuring that the radiation value of the oral shooting equipment will not exceed the standard.

[0049] 4. The oral photography device provided by the present invention, the second controller comprises: a control unit, and a blocking member driven by the control unit to move toward the rotating arm to limit the rotating arm from the folded state to the unfolded state. The blocking member is a baffle driven to move parallel to the rotating arm in the folded state; and / or, the rotating arm comprises at least two rotating rods connected in hinged connection, and the blocking member is a telescopic rod provided at the hinged position of adjacent rotating rods, and the telescopic rod is driven to connect the adjacent rotating rods to limit the relative rotation of the two.

[0050] The control unit controls the baffle and / or the telescopic rod to prevent the rotating arm from switching to the unfolded state, and the implementation method is simple and reliable. Moreover, the telescopic rod has the advantages of small size and small space occupation.

[0051] 5. In the oral photography equipment provided by the present invention, the first controller is communicatively connected with the camera power supply component of the oral camera to control the start and stop of the camera power supply component; and / or the second controller is communicatively connected with the radiograph power supply component of the intraoral radiograph to control the start and stop of the radiograph power supply component.

[0052] The first controller and the second controller can also directly cut off the power supply to the oral camera or the intraoral radiograph so that the oral camera and the intraoral radiograph cannot work at the same time. The above method can effectively ensure that the radiation value of the oral photography equipment will not exceed the standard.

[0053] 6. The oral photography equipment provided by the present invention, wherein the intraoral radiograph is installed on the inner wall side wall of the shielding room or on the oral camera or on a mounting frame.

[0054] The intraoral radiograph can be installed in various ways to adapt to different environments, thereby increasing the convenience of use for users. When the intraoral radiograph is installed on an oral camera, there is no need to set up a mounting frame or install a bracket on the wall, which can effectively reduce the complexity of installing the oral camera equipment, thereby increasing the convenience of installing the oral camera equipment.

[0055] 7. The oral photography device provided by the present invention and its control method,

[0056] The method comprises the following steps: S1, starting one of the oral camera and the intraoral radiograph; S2, the sensor detects that the action mechanism and / or the radiation generating mechanism of one of the oral camera and the intraoral radiograph is started, and the first controller or the second controller receives the signal sent by the sensor to control the action mechanism and / or the radiation generating mechanism of the other of the oral camera and the intraoral radiograph to be disabled. The above-mentioned interlocking mechanism can prevent the oral camera and the intraoral radiograph from working at the same time, thereby ensuring that the radiation value of the oral photographing device will not exceed the standard. It is possible to complete the four functions of CT, panoramic film, cranial photography and intraoral film by one oral photographing device, avoiding the need for two shielded rooms and separate oral cameras and intraoral radiographs for existing oral photographing devices, thereby reducing the construction and use costs of the oral photographing equipment.
