光纤内窥镜液氮冷冻诊治仪随着低温外科学的发展,冷冻疗法已在皮肤科、妇科、眼科、耳鼻喉科、肿瘤科、泌尿科和肛肠科等医学领域成为有效的治疗手段,具有手术简单、迅速安全、无需麻醉,不流血、不感染、疤痕小、手术费用低等优点。但目前国内外其它液氮冷冻治疗仪由于没有解决液氮传输技术,均只能用于治疗浅表病灶,对内腔病灶无能为力,这在很大程度上限制了冷冻疗法的应用范围。光纤内窥镜液氮冷冻诊治仪采用负压液氮双相传输技术与光纤内窥镜相耦合,是一种既可检查又能冷
With the development of cryogenic surgery, cryotherapy has become an effective treatment in medical fields such as dermatology, gynecology, ophthalmology, otolaryngology, oncology, urology and anorectal surgery, and has the advantages of Surgery is simple, fast and safe, without anesthesia, no bleeding, no infection, small scars, low cost of surgery. However, at present, the other liquid nitrogen cryotherapy devices at home and abroad have not been able to solve the problem of liquid nitrogen transmission technology and can only be used for the treatment of superficial lesions and for the lesions of the internal cavity, which greatly limits the application range of cryotherapy. Fiber optic endoscope cryogenic liquid nitrogen diagnosis and treatment instrument using negative pressure liquid nitrogen biphasic transmission technology coupled with the optical endoscope, is a can check both cold
