RADIALLY EXPANDABLE ACCESS SYSTEM HAVING DISPOSABLE AND REUSABLE COMPONENTS

摘要

An access system comprises a radially expandable sleeve (10), a pneumoperitoneum needle (20), a cannula assembly (40), and an obturator (60). Methods for reconstructing and reusing the access system comprises replacing the radially expandable sleeve (10), and cannula valve cap (46) 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.
