Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a visual high-speed turbine dental handpiece. Background Art

[0002] Endoscopes also have numerous limitations in clinical practice. First, the endoscope lens is susceptible to air and water mist. When the handpiece begins to rotate to separate the teeth, the mouth is filled with water mist and fluid, which can easily blur the lens surface, making it difficult for the surgeon to observe the surgical area in real time. Second, the light source of existing endoscopes generates glare when passing through the sapphire lens, affecting the real-time imaging effect of the endoscope.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a visual high-speed turbine dental handpiece to solve the technical problems existing in the prior art.

[0006] In an optional embodiment, the nozzle assembly includes a connecting column, and a guide cap is provided above the connecting column, and the diameter of the guide cap is larger than the diameter of the connecting column.

[0007] In an optional embodiment, a groove is provided on the guide cap, and an arc surface is formed on the inner side of the guide cap through the groove, and the opening direction of the groove is set toward the endoscope body; the medium channel inside the connecting column extends to the groove.

[0008] In an optional embodiment, the medium passing through the nozzle assembly is liquid or gas.

[0009] In an optional embodiment, the connecting column of the nozzle assembly is fixedly installed in the second installation cavity of the head assembly.

[0010] In an optional embodiment, the endoscope body is inserted into a cover and fixed, the end of the cover is a lens, the cover and the lens are integrally formed, and the cover is opaque.

[0011] In an optional embodiment, a plurality of LED lights are evenly arranged on the outer periphery of the cover.

[0012] In an optional embodiment, the cover body is fixedly connected to the support ring, the support ring is fixedly installed in the top groove of the first installation cavity, and multiple LED lamps are fixedly installed on the support ring. After the multiple LED lamps are installed, they are located as a whole in the top groove.

[0013] In an optional embodiment, the medium passing through the nozzle assembly forms an air curtain or a water curtain with a certain thickness, and the air curtain or the water curtain covers the entire lens.

[0014] In an optional embodiment, the lens is a sapphire lens.

[0015] The beneficial effects of the present invention are:

[0016] (1) A nozzle assembly is provided on one side of the visualization component of the dental handpiece. The nozzle assembly changes the direction and shape of the medium to form an air curtain that covers the entire sapphire lens. During operation, the endoscope lens can be kept clear and not contaminated, so that the endoscope image is always clear.

[0017] (2) The endoscope body of the visualization component of the dental handpiece is not equipped with a light source. By arranging multiple LED lights on the outside of the cover body that is integrally formed with the sapphire lens, the light source generated by the LED lights no longer passes through the sapphire lens, thereby avoiding the generation of glare and improving the clarity of the endoscopic imaging.
