经腹腔小切口输卵管结扎术,是当前绝育手术的主要方法之一,但由于切口小,往往需要器械取管或器械辅助取管,给手术者带来一定的困难,也给受术者增加痛苦。我们设计了一种导光拉钩,对解决这个问题有所帮助。 Transabdominal small incision tubal ligation, is currently one of the main methods of sterilization, but because of small incision, often need to take equipment or equipment to take care of the tube, to the operator to bring some difficulties, but also to the subject to increase pain . We designed a light guide hook, to solve this problem.
