Anti-fogging device for laparoscopic lens

Abstract

The invention discloses an anti-fogging device for a laparoscope lens, and relates to the technical field of laparoscopes. The anti-fogging device comprises a laparoscope shell, and a laparoscope jacket is arranged on an outer wall of the laparoscope shell; a laparoscope grip fixedly mounted at a front end of the laparoscope shell, and the laparoscope shell is matched with the laparoscope grip; a mounting shell fixedly arranged above a endoscope mounting block, and a mounting cavity is formed in the mounting shell; and a fixing block fixedly installed on an inner wall of the laparoscope shell, and one side of the fixing block is connected with a guide rod. The anti-fogging device is provided with a temperature warning device which can receive a temperature detected by an infrared temperature sensor, and when the temperature is too high, an arranged loudspeaker gives out a warning sound to remind a doctor, so that operation of the doctor is facilitated, and the temperature of a front end of the laparoscope is prevented from being too high.

Description

technical field [0001] The invention relates to the technical field of laparoscopy, in particular to an anti-fogging device for a laparoscope lens. Background technique [0002] Laparoscope is an advanced medical equipment that integrates mechanical, electrical and optical technologies. The operation must have the conditions of pneumoperitoneum and light guide equipment. It is widely used in various minimally invasive surgeries in gynecology, general surgery, urology and hepatobiliary surgery. Operation. Laparoscopic surgery uses a cold light source to provide illumination. Medical (carbon dioxide) CO2 gas is generally used to establish the pneumoperitoneum, and CO2 gas is used to create an artificial pneumoperitoneum as a space for observation and operation. A small hole in the abdominal cavity is used to establish a channel between the abdominal cavity and the outside world. A laparoscopic lens (about 5-10 mm) with a camera system and light source is inserted into the abd...

Problems solved by technology

Iodophor is a kind of surfactant, which weakens the adhesion of fog to the lens and makes the image clear. However, the anti-fog effect of this method is better within 30 minutes, but the effect is not good after 30 minutes. When the operation time is long , most of the anti-fog measures need to be repeated again or several times. There is a disadvantage of repeatedly entering and exiting the abdominal cavity for anti-fog treatment during the operation, and wipe the surface of the lens with wet gauze before wiping the iodophor cotton ball. If dry gauze is used It may cause damage to the lens, and iodophor is a colored liquid. It is best to wipe the anti-fog of the lens before adjusting the white balance of the laparoscope, and after wiping the iodophor, it needs to be wiped with a dry cotton ball. If there is excess iodophor to cover the lens , it may affect the judgment of the surgeon on the color of the abdominal organs, and the disadvantages of allergic reactions may occur in patients allergic to iodine
