Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laparoscopes, in particular to a laparoscope smoke removal structure. Background Art
[0002] With the development of medical technology, with the help of various sophisticated electrosurgical instruments, many operations can be completed under laparoscopy, reducing the trauma of patients and shortening the recovery time. However, during laparoscopic surgery, some harmful surgical smoke will be generated. These surgical smoke include gaseous substances or aerosols, burning smoke, and thermal plumes generated during the operation. It is mainly composed of 95% water or steam and 5% cell fragments in the form of particles; the pneumoperitoneum machine is a medical device that is widely used in laparoscopic surgery in surgical operations. It can provide a clear field of vision and working space by injecting carbon dioxide gas into the abdominal cavity.
[0003] However, most traditional methods of smoke removal during laparoscope use an insufflator to treat the generated smoke. However, since the insufflator is located inside the operating room, the odor cannot be completely treated after ventilation, and a smell similar to burnt meat will still remain in the operating room, resulting in odor during actual use.
