Thoracoscope lens cleaning and demisting device

Abstract

The invention provides a thoracoscope lens cleaning and demisting device. The thoracoscope lens cleaning and demisting device comprises a body, a liquid supply pipe, a liquid return hose, a negative pressure hose, a switch assembly, an overflow valve and a nozzle. Through the cooperation of the switch assembly, the liquid return hose, the negative pressure hose and the overflow valve, when a button is not pressed, heating physiological liquid provided by the liquid supply pipe heats a lens through a solution cavity set so that the temperature of the lens can be kept the same as the temperaturein the human body; after the button is pressed down, the liquid return hose is blocked, the negative pressure hose is unblocked, physiological liquid discharged by the overflow valve is sprayed out by the nozzle to wash the lens, and the physiological liquid sprayed out by the nozzle and other substances such as fog and bloodstain on the lens are sucked away by an arc-shaped suction port. The functions of heating and cleaning the lens are achieved, the functions of directly washing and directly heating a mirror surface are achieved, and re-fogging can be effectively prevented; and the double-delay function that spraying is delayed to be started when suction is started and suction is delayed to be stopped when spraying is stopped is achieved. And the function of cleaning mirror surface pollutants in a suction-only manner is realized.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for surgical instruments, in particular to a device for cleaning and defogging a thoracoscopic lens. Background technique [0002] Thoracoscopic surgery is the abbreviation of Video-Assisted Thoracic Surgery (VATS). Its essence is to use "laparoscopy" to perform surgery (or called laparoscopic surgery). [0003] In the actual operation of thoracoscopic surgery, although the support of the bony thorax can provide a certain space for endoscopic operation, in the limited space, when using high-energy instruments such as electric knife, ultrasonic knife, and energy platform to separate the wound surface and In the process of cutting tissues and blood vessels, oil droplets, blood droplets, water mist, etc. will inevitably contaminate the lens of the endoscope. Coupled with the blood stains flowing from the incision of the endoscopic sleeve (Trocar) along the endoscopic body, the endoscopic le...

Problems solved by technology

After putting the cleaned lens back into the chest cavity, due to the difference between the operating room room temperature (20-24°C) and the chest cavity temperature (37°C), the lens will often fog up and need to be re-wiped or soaked in hot water for a long time It takes a long time to put it into the chest again after warming

Repeated contamination will greatly prolong the operation time, increase the dosage of anesthetics, increase the energy and physical effort of the operator, and there will be repeated pulling of organs and repeated operations due to rearrangement of the field of view, which may lead to severe surgical complications. Complications such as bleeding and injury
