Problems solved by technology

[0003] The existing technology uses a dedicated person (nurse or doctor) with high labor costs, low efficiency of multiple air blowing and demisting, increasing oral humidity, demisting effect is getting worse, air bag blowing airflow is in the form of points or jets. Poor airflow stability, thus increasing the difficulty of surgery-patient pain-medical costs and affecting the effect of oral and dental microsurgery

Embodiment Construction

[0013] The following are suitable embodiments of the present invention, and the practical use of the present invention is not limited to the suitable embodiments.

[0014] Suitable embodiment 1 The demister on the surface of the optical lens of the operating microscope

[0015] The demister on the surface of the optical lens of the operating microscope with the structure of the present invention is composed of the large objective lens frame (1), the sealing ring (3), the sealing ring (2) and the optical lens under the sealing ring (2). Lens (5), in which the large objective lens frame (1) and sealing pressure ring (3) are made of cast aluminum alloy, and matched with food-grade rubber sealing ring (2), the demister on the surface of the assembled microscope optical lens meets the Process technical requirements.

Abstract

The invention provides a surface demister of an optical lens of an oral dental surgical microscope. According to the surface demister, an electromagnetic valve is arranged on an optical lens large objective lens frame (1) to control compressed air to pass through an air inlet pipe hole (7), a compressed air flow supplying delayed-conveying air inlet groove (4) and a connecting air passage of the groove and air blowing holes (6) and then enter the air blowing holes (6) distributed in an inner ring of the optical lens large objective lens frame (1) at equal intervals. The air blowing holes spray orderly controlled high-pressure air flow to the optical lens (5) under a sealing pressing ring (3) and a sealing ring (2). Thus, stains on the surface of the lens (5) are blown away by the sprayed air flow.

Description

technical field [0001] The present invention relates to a device demister for lens surface fog on the optical microscope lens of oral cavity and dental microsurgery, in particular to a demister that can automatically clear the space between the oral cavity and the microscope lens in time, and the adhered fog on the glass surface of the surgical optical microscope frame. Fog device - In-mirror defogger for optical microscopes. 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. [0003] The existing technology uses a dedicated person (nurse or doctor) with high labor costs, low efficiency of multiple air blowing and demisting, increasing oral humidity, demisting effect is ...
