Embodiment Construction

[0020] As mentioned in the background technology, the hot salt water bath anti-fog method needs to replace the hot salt water, the operation process is complicated, and the hot salt water immersion is also easy to damage the lens; the anti-fog oil used in the anti-fog method is expensive. Use a syringe to extract about 0.2mL of anti-fog oil for surgical operations. Repeated extractions will make the anti-fog oil susceptible to contamination. The iodophor wiping method has a good anti-fog effect and is safe and convenient to use. However, iodophor is a colored liquid, and the white balance of the laparoscope needs to be adjusted before wiping the lens, so as not to affect the surgeon's judgment on the color of the abdominal viscera. When the operation time is long and the anti-fog is wiped many times during the operation, the nurse needs to wipe the fogged lens with iodophor gauze, and then wipe the lens with a dry cotton ball to avoid excess iodophor covering the lens, so that ...

Abstract

The invention discloses a demister for a lens of a laparoscope. The demister comprises a housing, a heat pipe, a heating unit, isolating plugs, a cleaning barrel, hairbrushes, a cover plate, a porousmedium and cotton gauze; the housing includes a laparoscope hole; the porous medium is arranged at the bottom part of the laparoscope hole; the cotton gauze is arranged on the porous medium; the cleaning barrel is detachably arranged at one end, away from the porous medium, inside the laparoscope hole; the hairbrushes are arranged in the cleaning barrel; the two isolating plugs are arranged between the cleaning barrel and the porous medium in a spaced manner; the heat pipe is arranged between the two isolating plugs in the laparoscope hole; the heating unit is arranged on the outer wall of theheat pipe; and the cover plate is arranged on the housing. According to the demister for the lens of the laparoscope, mist prevention is automatically completed by wiping the lens with iodophor and iodophor protective films of multiple times of mist prevention measure are uniform in thickness, the operation is simple and convenient, and the surgery time is shortened.

Description

technical field [0001] The invention relates to the field of laparoscope technology, in particular to a laparoscope lens defogging device. Background technique [0002] In laparoscopic surgery, a laparoscopic lens is inserted through a puncture hole into the abdominal cavity to observe the abdominal viscera. Because the temperature of the laparoscopic lens is lower than that in the abdominal cavity, after the lens enters the abdominal cavity, the heat in the abdominal cavity will quickly form fog on the surface of the lens to blur the lens. In order to prevent the laparoscopic lens from fogging, there are three common solutions: first, the equipment nurse puts the laparoscopic lens in sterile saline at a temperature of 70±10°C to preheat for about 5 minutes before the operation, and then quickly puts the laparoscopic lens into The lens is placed in the abdominal cavity. When the temperature of the lens is higher than that of the abdominal cavity, the water vapor will not li...
