在小切口经腹结扎输卵管所暴露的腹腔术野是有限的,黑洞洞的。怎样才能变盲视手术为直视手术呢?关键问题是照明。倘若把腹腔外照明改为腹腔内照明,矛盾就迎刃而解。我们反复研究和实践由灯和镊子结合形成光镊。并把用这种光镊探寻输卵管的方法,初步称为光镊寻法。光镊既有腹腔“探照灯”的作用,又有镊子夹取输卵管、推送肠管及大网膜等功能,因而光镊具备结构简单、使用方便、效果确实的优点。通过实验证明, In a small incision lumbar tubal exposed abdominal surgery field is limited, black hole. How to turn blind surgery as direct vision surgery? The key issue is lighting. If the extraperitoneal lighting into intraperitoneal lighting, the conflict will be solved. We repeatedly study and practice the combination of light and tweezers to form optical tweezers. And use this method of optical tweezers to explore the fallopian tubes, initially called optical tweezers look-up method. Optical tweezers not only have the function of abdominal “searchlight”, but also tweezers grip the fallopian tubes, pushing bowel and omentum and other functions, so optical tweezers with simple structure, easy to use, the effect is indeed the advantage. Through experiments,
