Laparoscope antifogging device of thoracic surgery operating instrument

Abstract

The invention discloses a laparoscope antifogging device of a thoracic surgery operating instrument. The device comprises a laparoscope body and a displayer, one side of the laparoscope body is electrically connected with the displayer through a wire, the displayer is composed of a display screen and a signal converter, the laparoscope body comprises a handle, a connecting shaft, a rotating disc and a laparoscope tube, the connecting shaft is arranged at the upper end of one side of the handle, the upper end of the connecting shaft is movably connected with a rotating disc in a nested mode through a bearing, and the laparoscope tube is arranged at the upper end of the rotating disc. According to the laparoscope antifogging device of the thoracic surgery operating instrument, an observation lens is heated through a heating net, the temperature of the observation lens is increased at a constant speed, it is guaranteed that the temperature of the observation lens is consistent with the temperature of the interior of an outer tube, the upper surface of a laparoscope lens is sequentially brushed through rotation of the outer tube and stretching of an electric air cylinder, and the antifogging device is comprehensive, free of dead corners and good in antifogging effect; and the electric air cylinder is connected with a remote controller through signal transmission, accurate remote control can be achieved, operation is easy, operation efficiency is improved, surgical risks are greatly reduced, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a laparoscopic anti-fog device for thoracic surgery instruments. Background technique [0002] Laparoscopic surgery is an important part of minimally invasive surgery. During laparoscopic surgery, maintaining a clear intraoperative field of view is the prerequisite for successful surgery, and it is also the key to reducing intraoperative damage and shortening the operation time. However, due to the There is a large difference between the temperature of the body cavity and the outside temperature, and the lens is prone to water mist and contamination of the lens by blood and body fluids, which will affect the surgical operation. Therefore, anti-fog treatment of the lens during the operation is essential. However, the traditional anti-fog method still has the following problems: [0003] 1. The traditional anti-fog treatment of laparoscopic lenses usually uses high-tem...

Problems solved by technology

[0003] 1. The traditional anti-fog treatment of laparoscopic lenses usually uses high-temperature sterilized water for injection to preheat the lens. However, the duration is short. For long-term operations, frequent replacement of hot water is required, which greatly affects the progress of the operation and causes inconvenience to the operation. ;

[0004] 2. Use iodophor cotton ball to wipe the lens, and then wipe it with clean gauze to leave a film formed by iodine solution on the lens. However, the iodine solution is brown, causing the lens to be unclear, which improves the operation and observation of medical staff. Increased the difficulty and affected the progress of the operation
