[0003] In the existing ones, the nurse holds the blowing bag next to the surgeon. When the nurse sees water mist or the doctor signals, the nurse picks up the air bag and blows up the surface of the objective lens to remove the mist so that the doctor can continue the operation. This method usually does not clean up, leaving fog on the surface of the objective lens, resulting in blurred and blurred conditions when observing with a microscope, and the existing demister is not enough due to its cumbersome structure and is not convenient enough, and the intelligent mechanized demister is easy Damage to the objective lens, resulting in damage to the entire microscope instrument

The invention relates to the technical field of medical equipment cleaning. The invention especially relates to a surface demister for an optical lens of an oral dental operation microscope. The demister comprises a lens barrel and a clamping frame, an objective lens is arranged at a lower end of the lens barrel, one end of the clamping frame is fixed on the lens barrel through an orifice and a screw, another end of the clamping frame is fixedly connected with a connecting rod, a first bearing is arranged in the connecting rod, and an upper end of the connecting rod is fixedly connected to a telescopic rod. A rotating rod is arranged in the telescopic rod, a top end of the rotating rod is movably connected with the inside of the first bearing. The invention provides the surface demister for the optical lens of the oral dental operation microscope. The demister has the advantages that mist generated during an operation can be wiped off in time to keep the objective lens clear through aset cleaning mechanism, a set drying mechanism can quickly evaporate residual cleaning liquid of the wiped objective lens so that the objective lens can be kept clean and tidy, the arranged telescopicrod and clamping frame can be adjusted and detached, so that the operation hindering and visual field shielding are prevented.
Description
technical field [0001] The invention relates to the technical field of medical equipment cleaning, in particular to a demister for the surface of an optical lens of an oral dental operating microscope. Background technique [0002] Optical microscopes are often used in dental operations in hospital stomatology departments. Optical microscopes are optical instruments that use optical principles to magnify and image tiny objects that cannot be distinguished by the human eye, so that people can extract microstructure information. [0003] In the existing ones, the nurse holds the blowing bag next to the surgeon. When the nurse sees water mist or the doctor signals, the nurse picks up the air bag and blows up the surface of the objective lens to remove the mist so that the doctor can continue the operation. This method usually does not clean up, leaving fog on the surface of the objective lens, resulting in blurred and blurred conditions when observing with a microscope, and the...
