Optical lens surface demister for dental operation microscope

Abstract

The invention relates to the technical field of medical equipment, in particular to an optical lens surface demister for a dental operation microscope. The optical lens surface demister for the dentaloperation microscope comprises a microscope shell and a casing, wherein a lens is installed on one side inside the microscope shell, and the casing sleeves the outer side of the microscope shell. A gas cavity is formed between a limiting baffle, a gland plate and the casing, an air pipe communicating with the gas cavity is connected to the middle part of the outer side of the casing, and a heating device is connected to one end of the air pipe. A first gear is installed at the lower ends of sliding blocks, and the output end of a motor penetrates through the casing and is connected with a second gear meshing with the first gear. An inserting rod penetrates through one side of the first gear, and a sponge brush abutting against the lens is installed on one side of a second rotating rod. The optical lens surface demister for the dental operation microscope is simple in structure, convenient to use, good in use effect, high in practicability, time-saving and labor-saving, is capable of stably demisting the lens, and is worth of being popularized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a demister for the surface of an optical lens of an oral dental operating microscope. Background technique [0002] At present, during oral and dental microsurgery, the nurse holds the blowing bag next to the surgeon. When the nurse sees the mist or the doctor gives a signal, the nurse quickly picks up the blowing bag and blows on the surface of the lens for a few times, trying to dispel the mist. Remove and strive to continue the operation. During oral and dental microsurgery, since the microscope lens is about 200mm away from the patient's mouth, it is easy for the patient to spit out moisture mist to contaminate the optical microscope lens, and the aerosol formed on the surface of the lens will cause the microscope observation image to be blurred and aerosol It even interferes with oral cavity and dental microsurgery and is difficult to continue normally. In view o...
