A mirror anti-fog device for laparoscopic surgery

Abstract

The invention discloses a special endoscope surface demister for endoscopic surgery. The special endoscope surface demister comprises a cup body, a cup cover and an endoscope insert hole, wherein the cup body is matched with the cup cover; the endoscope insert hole is formed in the center of the cup cover; the endoscope insert hole is in a vertical circular tube shape and can be matched with an endoscope; an insert hole upper cover is arranged below the upper opening of the endoscope insert hole; an insert hole lower cover is arranged below the lower opening of the endoscope insert hole; torsional springs used for closing are arranged on rotating shafts of the insert hole upper cover and the insert hole lower cover; a water-absorbing sponge is arranged on each of the upper surfaces of the insert hole upper cover and the insert hole lower cover; a sponge layer covers the inner wall of the endoscope insert hole; the cup body is respectively provided with a waver volume display window and a temperature display meter. The special endoscope surface demister has the benefits that the whole demister is sealed, the effects of thermal insulation and preventing water leakage when a thermal insulation device is inclined are achieved, the insert hole upper cover and the insert hole lower cover can reset when the endoscope is taken out and the endoscope surface is wiped up at the same time, the sponge layer is adhered to the inner layer of the endoscope insert hole, so as to wipe an endoscope body, and the antifogging effect of the endoscope surface is guaranteed.

Description

technical field [0001] The invention relates to a mirror anti-fog device, more specifically, to a mirror anti-fog device for endoscopic surgery. Background technique [0002] At present, when laparoscopic surgery is performed, due to the temperature difference between the operating room and the body cavity of the human body, when the laparoscope enters the body cavity, the fogging of the mirror surface leads to blurring of the surgical field. In order to prevent blurring of the surgical field, some use hot water to prevent fogging, that is, Put sterile saline solution heated to 80°C into a round bowl to soak the mirror surface for 30s-1min, then dry it with gauze and put it into the body cavity; Wipe the mirror surface with a cotton ball, and use the film formed by iodophor on the mirror surface to play an anti-fog effect. Due to the temperature difference, the clarity of the mirror surface treated by this method is not as good as that of the hot water treatment method when ...

[0002] At present, when laparoscopic surgery is performed, due to the temperature difference between the operating room and the body cavity of the human body, when the laparoscope enters the body cavity, the fogging of the mirror surface leads to blurring of the surgical field. In order to prevent blurring of the surgical field, some use hot water to prevent fogging, that is, Put sterile saline solution heated to 80°C into a round bowl to soak the mirror surface for 30s-1min, then dry it with gauze and put it into the body cavity; Wipe the mirror surface with a cotton ball, and use the film formed by iodophor on the mirror surface to play an anti-fog effect. Due to the temperature difference, the clarity of the mirror surface treated by this method is not as good as that of the hot water treatment method when it first enters the body cavity. Continuation, when the temperature of the mirror surface is close to the temperature of the body cavity, its clarity is similar to that of hot water treatment; when the mirror surface touches human tissue during surgery, the clarity of the surgical field decreases due to blood and body fluids remaining on the mirror surface, and the above actions and processes often need to be repeated When treating the mirror surface with iodine, the clarity of the operative field has a certain time, which not only affects the operation process, but also affects the safety of the operation; hot water treatment of the mirror surface requires frequent replacement of hot water, which not only affects the operation process, but also increases the workload of nurses
