Thoracoscope lens device with flushing function

Abstract

The invention discloses a thoracoscope lens device with a flushing function. The thoracoscope lens device comprises a thoracoscope and a fixing sleeve; a through hole allowing the thoracoscope to penetrate through is formed in the middle of the fixing sleeve; the thoracoscope comprises a connecting rod, a lens and a handle; a groove is formed in the front end of the connecting rod, and the handle is arranged at the rear end of the connecting rod; a transparent plate and the lens are sequentially arranged in the groove from outside to inside; a closed liquid storage cavity is formed between the lens and the transparent plate; transparent conductive liquid is contained in the liquid storage cavity; electrodes are arranged on the two sides of the liquid storage cavity; the electrodes are electrically connected with a power source; and external light is collected by the lens after penetrating through the transparent plate and the liquid storage cavity. The transparent conductive liquid in the liquid storage cavity is electrified through the electrode to increase the temperature, the conductive liquid is directly contacted with the transparent plate, so that the whole transparent plate is heated, the specific heat capacity of the conductive liquid is high, the temperature is not easy to reduce after heat loss, and the lens is effectively prevented from being atomized.

Description

technical field [0001] The invention relates to the technical field of thoracoscope lenses, in particular to a thoracoscope lens device with a flushing function. Background technique [0002] Thoracoscopic surgery is a representative operation of minimally invasive thoracic surgery. The operation uses modern TV camera technology and high-tech surgical equipment to complete minimally invasive intrathoracic complex surgery under the chest wall sleeve or small incision. However, during the operation, the lens of the thoracoscope is easily fogged, and the fog adheres to the lens of the thoracoscope, causing the sight to be obstructed. The lens cleaning and defogging device uses heating around the lens of the thoracoscope. The heat gradually increases the temperature of the lens on the surface of the lens through heat transfer to avoid fogging of the lens. However, due to the thermal resistance of the lens on the surface of the lens, the heat does not It is easy to transfer to t...

AI Technical Summary

Problems solved by technology

However, in the process of performing the operation, the lens of the thoracoscope is prone to fogging, and the fog adheres to the lens of the thoracoscope and causes the line of sight to be obstructed. The lens cleaning and defogging device uses heat around the lens of the thoracoscope. The heat gradually increases the temperature of the lens surface lens through heat transfer to avoid lens fogging. However, due to the thermal resistance of the lens surface lens, the heat does not It is easy to transfer to the middle of the lens surface, and the specific heat capacity of the lens is small. When the heat of the lens is lost, the temperature of the lens will drop rapidly, so that the middle of the lens is not easy to heat, resulting in a high temperature that needs to be heated around the lens.
