A new surgical microscope device

Abstract

The utility model provides a novel surgical microscope device, including microscope body and smoke isolation adsorption device, smoke isolation adsorption device includes annular main part, annular main part is installed in the lens end of microscope body, is provided with annular air cavity and smoke collection cavity respectively in annular main part, gas transmission subassembly injects high pressure gas into annular air cavity, forms "air barrier" through the air jet mouth in front of the lens, like "intangible shield", will smoke isolate in the operation area, reduce smoke to the lens direction movement, simultaneously, the air inlet hole of smoke collection cavity inboard utilizes negative pressure and forms "local suction field", even if has a little smoke to break through gas curtain, also can be inhaled into collection cavity quickly, avoids the pollution lens or influence field of vision, and the application is through the design of cooperation inside and outside, and the device can efficiently realize "the double target of blocking smoke diffusion and purifying residual smoke", promotes the imaging definition of surgical microscope under the smoke environment.
