Description
Technical field
This utility model relates to a kind of gas-filtering device, particularly a kind of operation smoke filter.
Background technology
In recent years, laparoscopic surgery is more and more general in medicinal application.In laparoscopic surgery, when utilizing the equipment such as ultrasound knife, electric knife and laser to cut tissue, be and utilize heat to cause carbonized to volatilize, can operation smoke be formed.Patient, for ensureing that surgical field of view is clear, needs repeatedly or opens puncture casing air bleeding valve all the time, discharging a large amount of operation smoke.Confirm after deliberation, operation smoke is primarily of water vapour and cell debris granule composition, and granule is generally by chemical substance, blood and fragment of tissue, live virus, competent cell with can form by the material composition such as induced mutation.Wherein, the chemical composition merited attention comprises polycyclic aromatic hydrocarbon, acrylonitrile and Blausure (German) etc., is colourless toxic chemicals, and long-term absorption has cytotoxicity, genotoxicity to human body, cause the probability of chromosome breakage and Mutation induction.The pathogen such as human papillomavirus, hepatitis B virus or the Epstein-Barr virus that contain in operation smoke can infect corresponding disease simultaneously.Confirm at present, operation smoke is taken in the body of medical worker in operating room by skin, lung, mucosa and eyes, long-term chronic is taken in can cause mucocutaneous, upper respiratory tract irritation, simultaneously with carcinogenic, teratogenesis, and the serious consequence such as antibacterial, viral infection.
In addition, need lasting injecting carbon dioxide gas to maintain pneumoperitoneum in laparoscopic surgery, during open air valve, great amount of carbon dioxide is discharged with operation smoke.In operating room enclosed environment, the carbon dioxide pollution of air middle and high concentration can cause operating room technician to occur the symptoms such as headache, tinnitus, blood pressure increase, rapid breathing, absent minded, limbs fatigue.
The operation smoke that laparoscopic surgery is discharged and carbon dioxide are mainly collected at above operating-table, are very easily taken in by the medical personnel performed the operation.At present, the clean by laminar flow of clinical configuration, smog attract and the measure such as monolayer mask can not protect medical personnel to avoid the harm of operation smoke and carbon dioxide.Meanwhile, the surgical environments of operation smoke pollution also can cause harmful effect to patient health.Because the operation smoke that discharges in laparoscopic surgery and carbon dioxide easily cause employment injuries; long-term absorption can cause serious threat to operating room medical personnel; therefore effective equipment is badly in need of to reduce and eliminates the discharge of operation smoke and carbon dioxide; non smoke contaminated operation environment is built, the physical and mental health of protection medical personnel and patient in operating room.
