    Abstract: An access system comprises a radially expandable sleeve, a pneumoperitoneum needle, a cannula assembly, and an obturator. Methods for reconstructing and reusing the access system comprise replacing the radially expandable sleeve and cannula valve cap components of the system, both of which are disposable. All remaining system components may be sterilized and reused one or more times. The pneumoperitoneum needle can be separated into tubular needle body and needle stylet components, which may be separately replaced or sterilized and reused. Similarly the cannula comprises both a cannula hub and a cannula tube, where the hub and tube may be separately replaced or sterilized.

    Abstract translation: 进入系统包括径向可膨胀的套筒,气腹针,插管组件和闭孔器。 用于重建和重复使用进入系统的方法包括更换系统的径向可膨胀套筒和插管阀盖部件,这两者都是一次性的。 所有剩余的系统组件可以被灭菌并重新使用一次或多次。 气腹针可以分为管状针体和针刺针组件,可以单独更换或消毒并重新使用。 类似地,套管包括套管套管和套管管,其中轮毂和管可以单独更换或消毒。
