Description

Endoscope

Technical Field

The present utility model relates to an endoscope.

Background

Endoscopic minimally invasive surgery has become a type of surgery commonly employed throughout the world. However, in the use process, especially when the operation is started, the temperature of the endoscope is lower than the environment temperature in the human body, water vapor liquefies on the surface of the endoscope to form water mist, and a doctor has to wait or pause the operation until the image is clear, which causes great waste of operation time and inconvenience in operation.

In the prior art, although a researcher sets a heater at the lens end of an endoscope, the lens is heated by the heater, and the temperature of the lens is monitored by a temperature sensor, so that the lens is maintained in a target temperature range, and the purpose of defogging the lens is achieved. However, due to patient variability, such as a patient with thermal radiation, the internal temperature is generally higher than the normal temperature of the human body, and even if the lens reaches the target temperature, the lens may also be fogged. For the patients with hypothermia, the internal temperature is generally lower than the normal temperature of the human body, and when the lens reaches the target temperature, the lens is higher than the internal temperature, so that the hidden danger that the lens is contacted with human tissues to scald the patients can exist. Therefore, such endoscopes are poorly applicable.
