Technical Field
The utility model relates to the technical field of medical equipment, in particular to a low-cost laparoscopic surgery exhaust valve capable of being controlled by foot.
Background
In recent years, minimally invasive surgery, typified by laparoscopic surgery, has been widely used. In the process of laparoscopic surgery, a large amount of smoke generated by cutting equipment such as an ultrasonic knife, a high-frequency electrotome and the like seriously influences the surgical field of vision, and the high-concentration smoke is extremely easy to condense on a laparoscopic lens, so that the laparoscopic video is blurred, the surgical risk is increased, and the surgical time is prolonged. In operation, an assistant often needs to open an exhaust hole of a laparoscope sleeve to exhaust smoke or suck the smoke out by using an aspirator; on the other hand, the assistant needs to take out the lens frequently and wipe it with iodophor gauze, warm saline, etc. The series of operations seriously affect the operation process and waste human resources. In addition, the smoke contains harmful substances such as PM2.5, PM10, and living viruses, and the smoke is directly discharged into an operating room to seriously pollute the air of the operating room and harm the physical health of operating room workers.
At present, the automatic smoke discharging type cavity mirror equipment on the market is not popularized due to the purchase and use cost and the like. The smoke filtering device for laparoscopic surgery disclosed in patent document CN216498123U can filter and discharge smoke, but needs to be controlled by hand, occupies the hands of the surgeon, affects the surgical procedure, and wastes human resources. Patent document CN110693581A discloses a puncture outfit sleeve capable of automatically discharging smoke. Patent document CN109620390A discloses a laparoscope smoke automatic removing system, which adopts a smoke sensing device to automatically exhaust smoke, and although the smoke can be automatically exhausted theoretically, the laparoscope smoke automatic removing system is complex in structure, high in cost and limited in clinical conversion value. Moreover, the laparoscopic surgery is not always capable of exhausting air, for example, in the cases of narrow surgical field, free large blood vessels and the like, the collapse of the air cavity caused by the sudden air discharge and smoke exhaust affects the surgical operation.
Therefore, the prior art still cannot well meet the requirements of convenient and harmless emission of smoke in laparoscopic surgery and also has the problem of medical cost. There is a need for a more convenient, safer, and less costly smoke evacuation device to assist laparoscopic surgery.
