我们设计和使用的双管镰刀形前房注吸针的资料发表以来,有不少同道希望我们给予制作,并提出改进意见。为使这种器械更加完善和提高其实用价值,我们又进行了一些探索,取得了较满意的效果。现将有关改进措施报道如下。 Since the publication of the double-sided sickle-shaped hypodermic needle designed and used by us, quite a few of our colleagues hope that we will give them a make-up and propose improvements. In order to make this equipment more perfect and enhance its practical value, we conducted some exploration and achieved more satisfactory results. The relevant improvement measures are reported below.
