Laparoscope lens anti-fogging device

Abstract

The invention discloses a laparoscope lens anti-fogging device, which comprises a sheathing canal, deflection plates are arranged on the two sides of the bottom end of the sheathing canal, wiping mechanisms capable of smearing iodophor on a laparoscope lens when the laparoscope lens penetrates through the deflection plates are arranged on the deflection plates, and the sheathing canal is arranged at an opening of the abdomen of a patient. The surface of the laparoscope lens is smeared with iodophor when the laparoscope lens penetrates through the end of the sheathing canal, according to the laparoscope lens anti-fogging device, different from the prior art, based on an iodophor anti-fogging mode, the laparoscope lens does not need to be frequently pulled out to be smeared with iodophor in the laparoscope operation process, instead, when the lens fogs, the Trocar sheathing canal can be withdrawn into the laparoscope lens directly, and then is pushed out to enter the enterocoelia again, thus finishing iodophor coating on the surface of the laparoscope lens, and the laparoscope lens can be conveniently, effectively and quickly subjected to anti-fog treatment, so that the laparoscope lens treatment time is effectively shortened, and the laparoscope lens is effectively and conveniently used in clinical operations.

Description

Technical field [0001] The present invention relates to the field of laparoscopic techniques, in particular to a lens laparoscope fogging prevention means. Background technique [0002] Laparoscopy is a combination of mechanical, electrical, optical technology in one of the advanced medical equipment, surgery must have pneumoperitoneum conditions, a light guide apparatus and the like, are widely used in gynecology, various minimally invasive surgery in general surgery, urology, hepatobiliary surgery Operation. Laparoscopic surgery using cold light source to provide illumination, the general medical (CO) CO 2 Establishing pneumoperitoneum gas, the use of CO 2 As a result pneumoperitoneum gas space observation and operation, establishing the abdominal cavity and the outside passage holes through several ~ 1.0cm 0.5cm on the abdominal wall with a Trocar, with the imaging lens system and the light source Laparoscopic (about 5 to 10mm) by Trocar into the abdominal cavity, the use of e...

Problems solved by technology

[0003] However, during laparoscopic surgery, the laparoscopic lens often affects imaging due to fogging, and the reason for laparoscopic lens fogging is due to the temperature difference between the inside and outside of the abdominal cavity. If the temperature of the laparoscopic lens is lower than the temperature in the abdominal cavity, the After the lens enters the abdominal cavity, the hot air in the abdominal cavity encounters the cold lens, and part of the water vapor is very easy to condense, thus forming a layer of fog, which affects the clarity of the field of view on the monitor. A clear surgical field of view is the key to the safety of laparoscopic surgery. Therefore, the anti-fog treatment of laparoscopic lens is intuitive and important, therefore, the anti-fog treatment of laparoscopic lens is a problem that must be solved in practical operation

[0004] In the prior art, there are three common solutions to lens fogging: first, the instrument nurse puts the laparoscopic lens into sterile saline at a temperature of 60±10°C to preheat for about 1 minute before the operation begins , and then quickly put the lens into the abdominal cavity. When the temperature of the lens is higher than the temperature of the abdominal cavity, the water vapor will not liquefy on the surface of the lens and form fog to affect the sight. Replacement, like this, is not only time-consuming and laborious, but also very inconvenient to use; second, the iodophor wipe anti-fog method, that is, before the lens is placed in the abdominal cavity, wipe the front end of the lens with iodophor cotton balls, and then use cotton balls to wipe off the excess. Iodophor, because iodophor is an iodine-containing amorphous compound with smooth properties, it can form a protective film on the surface of the lens to isolate the heat in the abdominal cavity from adhering to the lens and play an anti-fog effect, but this method has the following disadvantages : The anti-fog effect is better within 30 minutes, but the effect is not good after 30 minutes. When the operation time is longer, it is still necessary to take anti-fog measures again or several times; third, anti-fog oil anti-fog method, in the laparoscopic lens Before entering the abdominal cavity, use a sterilized syringe to draw out a little anti-fog oil, then drop it directly on the top of the lens or drop it on a cotton ball, and then evenly spread it on the top of the laparoscopic lens to prevent foggy vision. The anti-fog oil can form on the surface of the lens A layer of monomolecular transparent film, which can prevent water vapor from condensing into water droplets, but most of the anti-fog oils for endoscopes on the market are imported from abroad, which are expensive and increase the burden on patients
