[0036] Please refer to the attached Figure 1-9 , the purpose of this embodiment is to provide a disposable visual dental handpiece, including: a head component 1 and a handle component 2. The head component 1 is connected to the handle component 2, and a visualization component 3 is provided on the head component 1. Among them, a first installation cavity 11 is formed in the head body 15 of the head component 1, and an endoscope body 31 of the visualization component 3 is arranged in the first installation cavity 11. A disassembly slot 23 is provided on one side of the handle body 22 of the handle component 2 away from the output end 14 of the head component 1. The disassembly slot 23 is arranged at one end of the handle body 22 close to the head body 15, and the disassembly slot 23 extends to the connection transition between the handle body 22 and the head body 15. The first installation cavity 11 is communicated with the disassembly slot 23.

[0037] In this embodiment, the endoscope body 31 is connected to the sub-seat 51 of the connector 5 through a front-end flexible cable 37, and the mother-seat 52 of the connector 5 is connected to a rear-end flexible cable 36. The connection end 38 of the front-end flexible cable 37 is welded to the top of the sub-seat 51, and the sub-seat 51 is detachably connected to the mother-seat 52. There are various detachable connection methods between the sub-seat 51 and the mother-seat 52, as long as they can be detachably connected to each other and conduct electricity. Those skilled in the art can choose according to the actual situation.

[0038] After the mobile phone is used up, disconnect the sub-base 51 from the mother base 52, take out the endoscope body 31 from the first installation cavity 11, and then take out the integrated endoscope body 31, the front end flexible cable 37, and the sub-base 51 through the disassembly slot 23; then install the endoscope body 31, the front end flexible cable 37, and the sub-base 51 into a new disposable visual dental handpiece without the endoscope body 31. The endoscope body 31 is inserted into the first installation cavity of the new disposable handpiece, and the sub-base 51 is plugged into the mother base of the new disposable handpiece. The endoscope body can be reused, saving the use cost.

[0039] It should be noted that the handpiece assembly 1 is also provided with a nozzle assembly 4. The axis of the nozzle assembly 4 is parallel to that of the visualization assembly 3; the endoscope body 31 of the visualization assembly 3 is arranged towards the output end 14 of the handpiece assembly 1; the nozzle assembly 4 changes the direction and shape of the medium and transfers the medium to the front of the endoscope body 31.

A guiding cap 42 is arranged above the connecting column 41, and the diameter of the guiding cap 42 is larger than that of the connecting column 41. A slot is opened on the guiding cap 42, and an arc surface 44 is formed inside the guiding cap 42 through the slot. The opening direction of the slot is arranged towards the endoscope body 31; the medium channel 43 inside the connecting column 41 extends to the slot. In this embodiment, the medium passing through the nozzle assembly 4 is gas or liquid. Through the above structure, the medium changes the flow direction and shape under the action of the arc surface 44 to form an air curtain or a water curtain with a certain thickness. The air curtain or the water curtain covers the entire sapphire lens, and the air curtain or the water curtain fits the surface of the sapphire lens, ensuring that other impurities do not enter the lens area and ensuring a clear field of view. The connecting column 41 of the nozzle assembly 4 is fixedly installed in the second installation cavity 13 of the handpiece assembly 1.

[0041] Specifically, the front end of the endoscope body 31 can be inserted into the cover body 33. The end of the cover body 33 is a lens 32. The cover body 33 and the lens 32 are integrally formed. A plurality of LED lights 35 are evenly arranged on the outer peripheral side of the cover body 33. The cover body 33 is fixedly connected with the support ring 34 in a limited way. The support ring 34 is fixedly installed in the top groove 12 of the first installation cavity 11. A plurality of LED lights 35 are fixedly installed on the support ring 34, and the whole is located in the top groove 12 after the installation of the plurality of LED lights 35. And the cover body 33 is light-tight, so that the light source generated by the LED lights no longer passes through the sapphire lens, avoiding the generation of glare and improving the clarity of the endoscope imaging.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
