Problems solved by technology

[0002] Medical endoscopes have been widely used in minimally invasive surgery. One of the operating defects of the current minimally invasive surgery using the endoscope system is: when the endoscope enters the human body for operation, due to the temperature difference between the inside and outside of the human body, part of the water vapor encounters When the temperature of the endoscope is low, it is easy to form condensation fog on the optical window in front of the endoscope, which will affect the imaging clarity of the surgical field, blur the image of the surgical field displayed on the monitor, and affect the doctor's observation and operation
In order to overcome the fogging of the endoscope, doctors mainly use physiological saline to preheat the endoscope, apply anti-fog oil, etc., which can alleviate the problem of endoscope fogging to a certain extent, but the disadvantage is that it complicates the surgical preparation process, There are hidden dangers of incomplete disinfection and increased surgical preparation time, so providing anti-fog or demist solutions directly from the endoscope system is the best way

Embodiment 1

[0015] The white light illumination source 11 is a white light LED with a total power of 80W. The near-infrared anti-fog illumination source 12 is a semiconductor laser with a radiation wavelength of 808nm and a full power output of 5W. The pass rate is 90%. When the near-infrared anti-fog lighting source 12 is turned on at full power for 1 minute, the temperature of the front optical window 32 rises from about 25°C at room temperature to about 37°C, the power drops to 30% of the full power, and the temperature remains at about 37°C.

[0016] The working principle is: 2~3 minutes before the operation, turn on the 808nm semiconductor laser, output 5W 808nm laser, the 808nm laser passes through the color combination filter 13 and then reflects into the coupling optical lens 14, and the coupling optical lens 14 converts the 808nm near The infrared light is focused and coupled into the transmission fiber bundle 2, and emerges from the exit surface of the transmission fiber bundle ...

Embodiment 2

[0018] The white light source 11 is a red, green and blue primary color mixed white LED with a total power of 170W. The near-infrared anti-fog light source 12 is a semiconductor laser with a radiation wavelength of 940nm and a full power output of 10W. The front optical window 32 has an absorption rate of 90 at 940nm. %, the average transmittance of visible light is 85%. The near-infrared anti-fog lighting source 12 is turned on at full power for 30 seconds, the temperature of the front optical window 32 rises from about 25°C at room temperature to about 37°C, the power drops to 10% of the full power, and the temperature remains at about 37°C.

Embodiment 3

[0020] The white light illumination source 11 is a xenon lamp with a total power of 350W. The near-infrared anti-fog illumination source 12 is a Nd:YAG laser with a radiation wavelength of 1064nm and a full power output of 7W. The pass rate is 80%. The near-infrared anti-fog lighting source 12 is turned on at full power for 45 seconds, the temperature of the front optical window 32 rises from about 25°C at room temperature to about 37°C, the power drops to 20% of the full power, and the temperature remains at about 37°C.

[0021] The working principles of Embodiment 2 and Embodiment 3 are similar to those of Embodiment 1, and will not be repeated here.

[0022] The device and method of the anti-fog endoscope system of the present invention are suitable for use in various endoscopic operations, especially in endoscopic operations in which the endoscope needs to be inserted and pulled out of the human body repeatedly, so as to play an anti-fog function.

Abstract

The invention relates to an anti-fog endoscope system device and method, and belongs to the technical field of minimally invasive medical treatment. On the basis of a traditional endoscope system, a near-infrared anti-fog lighting light source is additionally provided and enters a lighting transmission channel in a mixed color coupling mode, material characteristics of a front optical diaphragm are changed so that visible light can penetrate through the front optical diaphragm, white-light illumination of a surgery field is guaranteed, meanwhile, near-infrared light energy is absorbed and the temperature of the front optical diaphragm rises, the temperature difference of the front optical diaphragm of an endoscope and the human body is reduced, and therefore the anti-fog aim is achieved. Compared with the anti-fog methods of preheating normal saline and coating anti-fog oil, the method has the advantages that a doctor can carry out an operation more conveniently and easily, the hidden risks that normal saline, anti-fog oil and the like are not sufficiently disinfected are avoided, and the method is suitable for being used in various endoscope operations and is especially suitable for being used in the endoscope operations where an endoscope is repeatedly inserted into and pulled out of the human body so as to achieve the anti-fog function.
