Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically to an oral caries detection device applicable to MR equipment. Background Technology

[0002] Dental caries, commonly known as cavities or tooth decay, is a bacterial disease that can lead to pulpitis and periapical periodontitis, and even inflammation of the alveolar bone and jawbone. It is a progressive lesion of the hard tissues of the teeth caused by the combined effects of multiple factors in the oral cavity, manifested as demineralization of inorganic matter and decomposition of organic matter, evolving from color changes to the formation of substantial lesions as the disease progresses. To treat dental caries, people often go to dental hospitals for examination and treatment. During treatment, doctors will use an intraoral endoscope to examine the patient's teeth.

[0003] Current oral endoscopes typically cannot assist patients in opening their mouths, leading to discomfort due to prolonged mouth opening during examinations and damage to the endoscope lens from sudden mouth closure. Furthermore, traditional oral endoscopes mostly have fixed lenses, making it difficult to change the lens direction when examining teeth in different directions (left, right, top, bottom), increasing the risk of the endoscope touching the patient's mouth. Additionally, currently, dental interns primarily acquire and enrich their medical skills through observing treatment processes in clinical settings, assisting attending physicians, and limited practical opportunities. During observation, interns lack firsthand experience of the treatment process, diminishing their learning experience.

[0004] Therefore, how to provide an oral caries detection device that can assist patients in opening their mouths, relieve mouth fatigue, reduce discomfort, and allow for convenient viewing of teeth from different directions, thereby improving the learning experience of interns and facilitating their rapid mastery of medical skills, and which can be applied to MR equipment, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides an oral caries detection device applicable to MR equipment that can assist patients in opening their mouths, relieve mouth fatigue, reduce discomfort, and allow for convenient viewing of teeth from different directions, thereby improving the learning experience of interns and facilitating their rapid mastery of medical skills.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oral caries detection device applicable to MR equipment, comprising:

[0008] A medical bed, wherein a control display is installed on the medical bed;

[0009] A support frame, the bottom end of which is fixedly connected to one side of the top of the medical bed;

[0010] A lifting auxiliary mouth opening mechanism is installed on the support frame and used to assist in opening the mouth of the patient, and the lifting auxiliary mouth opening mechanism is electrically connected with the control display;

[0011] A rotating TOF camera mechanism is installed on the lifting auxiliary mouth opening mechanism, the rotating TOF camera mechanism is electrically connected with the control display, and the rotating TOF camera mechanism is used to take pictures of the teeth at different positions in the oral cavity of the patient and upload the pictures to the control display for display.

[0012] An MR device is electrically connected with the control display.

[0013] According to the technical scheme, compared with the prior art, the application discloses a dental caries detection device applicable to an MR device. When in use, the patient lies on a medical bed, and then the lifting auxiliary mouth opening mechanism is lowered and opens the oral cavity of the patient. At this time, the rotating TOF camera mechanism is driven by the lifting auxiliary mouth opening mechanism to enter the oral cavity of the patient and take pictures of the teeth from different directions. At the same time, the images taken are displayed in real time on the control display for the doctor to observe and understand the dental disease. Therefore, the device uses the lifting auxiliary mouth opening mechanism to assist the patient in opening the mouth, and the patient does not need to forcibly open the mouth by himself. This can reduce the discomfort of the patient's mouth caused by forcibly opening the mouth for a long time. In addition, the control display sends the high-resolution video images of the teeth and the doctor's hand movements collected by the TOF camera to the MR device. The MR device establishes a 3D model of the teeth and the doctor's hand through image processing to generate a virtual reality environment and complete rendering. The dental disease state and the doctor's treatment process are recorded and saved in the MR device. The intern doctor can use the MR device to experience the treatment process in person, improve the learning experience of the intern doctor, and quickly master the medical skills.

[0014] Further, the lifting auxiliary mouth opening mechanism comprises:

[0015] A lifting motor is fixed at the top end of the support frame.

[0018] The beneficial effects produced by the above technical scheme are that the lifting motor drives the lifting screw rod to rotate, the sleeve is lifted along the length direction of the lifting screw rod, and finally the auxiliary mouth opening supporting assembly is lifted.

[0019] Further, the auxiliary mouth opening supporting assembly comprises:

[0020] A lifting frame is slidably connected to one side of the support frame, a top end plate of the lifting frame is fixedly connected to the bottom end of the sleeve, a through hole is formed in a bottom end plate of the lifting frame, a pin shaft is fixed to the hole wall of the through hole, and the rotary TOF camera mechanism is installed on the bottom end plate;

[0021] A mounting plate is installed on the bottom end face of the top end plate, and a mouth opening supporting motor is fixed to one side of the mounting plate;

[0022] A forward and reverse screw rod is rotatably connected to both ends of the mounting plate, and one end of the forward and reverse screw rod is fixedly connected to the driving end of the mouth opening supporting motor;

[0023] Two sliding block nuts are respectively screwed on the forward and reverse screws of the forward and reverse screw rod, and the upper ends of the two sliding block nuts are slidably connected to the mounting plate;

[0024] Two support rods are hingedly connected to the lower ends of the two sliding block nuts, respectively, the two support rods are cross arranged through the pin shaft and pass through the through hole, and two oral cavity supporting blocks are fixedly connected to the other ends of the two support rods.

[0025] The beneficial effects produced by the above technical scheme are that after the auxiliary mouth opening supporting assembly is lowered into position, the mouth opening supporting motor drives the forward and reverse screw rod to rotate, thereby realizing the movement of the two sliding block nuts on the forward and reverse screw rod in opposite directions, and finally driving the oral cavity supporting blocks at the lower ends of the two support rods to open the patient's mouth. The mechanism is simple in structure and can realize the auxiliary mouth opening operation of the patient.

[0029] A rotary motor is fixed to the bottom end plate, and a driving gear is fixed to the driving end of the rotary motor;

[0030] The beneficial effects produced by the above technical scheme are that the rotary motor drives the driven gear to rotate through the driving gear, and then the rotary rod rotates, so that the illuminating lamp and the TOF camera on the rotary rod rotate, and finally the TOF camera can shoot the teeth in different positions under the auxiliary illumination of the illuminating lamp.

[0031] Further, the mounting plate is mounted on the bottom end face of the top end plate through the shock absorber.
