Description

Technical Field

[0001] The present invention relates to the technical field of oral medical equipment, and specifically to a display device for real-time positioning of an oral turbine handpiece. Background Art

[0002] An oral turbine handpiece is a high-speed rotating instrument widely used in dental surgeries. It is also called a dental high-speed handpiece or a high-speed pneumatic turbine handpiece. It is a commonly used medical device in dental treatments. Driven by the air pressure of a dental chair, it rotates at an extremely high speed and is very suitable for cutting, shaping, and removing hard dental tissues such as enamel or restorative materials. In daily dental clinical applications, a dental high-speed turbine handpiece is one of the very important treatment tools, which can greatly improve the efficiency and effect of oral clinical treatments, and at the same time greatly reduce the pain of patients during the treatment process.

[0003] Currently, there are some technical drawbacks in the use of precision oral high-speed and slow-speed handpieces in hospitals and clinics: First, it is difficult to accurately locate the depth of the pulp cavity, and there is a large error in the tactile judgment according to different doctors; Second, the dental anatomical structure is complex and difficult to distinguish, and at the same time, the internal oral cavity vision is limited, interfering with the judgment; Third, there is a lack of real-time warning. Summary of the Invention

[0004] In view of the deficiencies of the existing problems, the present invention provides a display device for real-time positioning of an oral turbine handpiece to solve the existing problems mentioned in the above background art.

[0005] To solve the above problems, the present invention is achieved through the following technical solutions: A display device for real-time positioning of an oral turbine handpiece includes an oral turbine handpiece and a terminal host. The oral turbine handpiece includes a handle and a head. The outer surface of the head is provided with a ranging hole, an LED lamp, and a water spray hole. The inside of the head is provided with a core and a sensing module. The sensing module includes a protective housing. Inside the protective housing, there are a micro laser rangefinder, a three-axis MEMS accelerometer, a piezoelectric ceramic vibration sensor, and a wireless transmission module. The terminal host includes a terminal display module, a central processing module, and a support frame. The terminal display module includes a terminal display body, an electronic liquid crystal touch screen, and a safety alarm module. The central processing module includes a metal housing, an FPGA signal processor, and a deep learning coprocessor.

[0006] Preferably, the bottom of the head is fixedly connected to the top of the handle, and the ranging hole is disposed opposite to the micro laser rangefinder.

[0007] Preferably, the central processing module is disposed on the outer surface of the terminal display module, and the support frame is fixedly connected to the bottom of the terminal display module.

[0008] Preferably, the bottom of the terminal display body is fixedly connected to the support frame, the electronic liquid crystal touch screen is arranged on the outer surface of the terminal display body, and the safety alarm module is arranged inside the terminal display body.

[0009] Preferably, the outer surface of the metal shell is fixedly connected to the outer surface of the terminal display body, and the FPGA signal processor and the deep learning coprocessor are arranged inside the metal shell.

[0010] Preferably, a USB interface is arranged on the outer surface of the metal shell, and the central processing module is electrically connected to the terminal display module.

[0011] The present invention provides a display device for real-time positioning of an oral turbine handpiece, which has the following beneficial effects:

[0012] First, in the display device for real-time positioning of an oral turbine handpiece, through the cooperation among the sensing module, the central processing module and the terminal display module, during use, relying on the principle of echo conduction, the position of the drill bit in the tooth is transmitted to the electronic liquid crystal touch screen in real time, reducing the losses caused by the feel errors of different doctors. This device can not only improve the operation accuracy, but also take into account the personal preferences and operations of different doctors, realizing easy application.

[0013] Second, in the display device for real-time positioning of an oral turbine handpiece, through the sensing module, the central processing module and the terminal display module: First, the accuracy of treatment is improved. During root canal treatment, the high-speed handpiece displays the real-time position. During the pulp opening stage, it can help the doctor clarify the distance between the drill bit and the pulp cavity, preventing excessive or insufficient drilling and grinding, and improving the accuracy of pulp opening. Second, the treatment risk is reduced. During root canal treatment, the high-speed handpiece displays the real-time position, enabling the doctor to master the operation in real time, avoiding the instrument from penetrating too deep into the apical foramen, reducing the damage to the dental pulp and periapical tissues, reducing postoperative complications, promoting the recovery of the patient. During the treatment of multi-root teeth, it can help the doctor adjust the operation in time, avoid side perforation and floor perforation, protect the integrity of the tooth, and improve the preservation rate of the affected tooth. And, the treatment efficiency is improved. The high-speed handpiece provides real-time position information, which helps the doctor quickly and accurately complete each step of root canal treatment, reducing the time-consuming of repeated exploration and adjustment, shortening the treatment time and improving the efficiency, saving time and energy for the patient. At the same time, it can reduce the dependence on X-ray films to a certain extent and reduce the number of X-ray irradiations of the patient, protecting the health of the patient. Finally, it is convenient for teaching and training. For dental students and beginners, the real-time position information displayed by the high-speed handpiece can visually present the relationship between the operation process of root canal treatment and the position of the instrument, helping them master the treatment technology and improving the teaching effect. At the same time, this information provides a standard operation reference for teaching, facilitating the teacher to guide and correct the operation of the students, helping them develop good habits and standardize the process, and improving their clinical skills.
