Description

technical field [0001] The invention relates to the field of medical auxiliary devices, in particular to an adjustable protective cover for a laparoscopic lens. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method, and it is an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasingly skilled operation of doctors, many open operations in the past have now been replaced by endovascular surgery. Greatly increased surgical options. The traditional method of retroperitoneal laparoscopic surgery is to make three small incisions of 1 cm on the patient's waist, each inserting a tube-shaped working channel called "trocar", and all subsequent operations are performed through these three channels; and then special length...

Problems solved by technology

[0004] Although using this kind of mirror protective cover can keep the mirror surface dry and the temperature constant, but during use, bloody aerosol or oily aerosol will pass through the gap between the flushing air hole and the isolation air hole, which will cause the mirror surface to be polluted, resulting in loss of vision. Fuzzy, some oil mist or blood clots block the pores, and at the same time, the surface of the mirror body is stained with blood clots and fat after use, which needs to be cleaned by medical staff, which is inconvenient to use
